Dear Fellow Shareholder:

As members of your Board of Directors, our primary focus is on creating long-term value for our shareholders. We accomplish that in a number of ways, from setting a clear strategic course for the company, to helping management develop sound operating and financial plans, to assuring that management executes those plans in a responsible manner.

Unum’s vision is to be the leading provider of employee benefits products and services that help employers manage their businesses and employees protect their livelihoods. In 2012, we continued to make steady progress toward this vision, delivering on our plan commitments and maintaining our record of consistently returning capital to our shareholders through dividend increases and share repurchases. Focus and discipline have served us well in the past, and we believe that will continue to be the case in the future.

We were generally pleased with the solid financial and operating results the company produced in 2012. We continued to perform well across most of the company and showed improvement in those areas that had been below expectations. While we still face challenges, we are confident that we are well-positioned to respond to those challenges and seize the opportunities that lie ahead. We were disappointed with the stock performance in 2012, but we are encouraged by the market’s recent recognition of the company’s steady performance and positioning for the future.

2012 Performance highlights(1)

| — |  | We reported pre-tax operating income of $1.24 billion and after-tax operating income of $887.5 million on operating revenues of $10.46 billion and operating earnings per share of $3.15, a 5.7% increase;

| — |  | We profitably grew premium (or revenue), while generating above average returns on equity in our operating businesses; and

| — |  | We continued our record of consistently returning capital to shareholders through dividend increases and repurchasing stock, which combined with our solid operating performance led to growth in earnings and book value per share.

Corporate governance

Corporate governance is very important to this Board of Directors. Transparency, accountability, integrity, and sound risk management form the foundation of our culture at Unum. We are pleased that our corporate citizenship efforts have been recognized by several independent organizations, including being named one of Forbes 100 Most Trustworthy Companies, a Corporate Leader in Political Disclosure and Accountability by the Center for Political Accountability, one of Newsweek’s Top 50 Green Companies, and one of the Best Places to Work in Insurance by Business Insurance.

Listening carefully to our shareholders is also an important part of our culture. Your continued feedback is invaluable to us as we work to fulfill our role as directors. Participation in our Annual Meeting is one of the important ways you can provide feedback to us. We also regularly solicit feedback from shareholders on key issues, and, as recent changes to our compensation program attest, strive to make changes as a result of listening to you.

A Letter from our Board of Directors

During the year, we conducted an outreach program to a number of institutional investors and proxy advisory firms to solicit input regarding our executive compensation programs and other governance matters. While shareholders generally approved of our overall executive compensation program, they suggested a number of ways to enhance our compensation elements and disclosures. Based on this feedback, we adjusted the mix and some of the goals in our long-term incentive plan, provided a more detailed explanation of the rationale behind our compensation decisions, and enhanced the disclosure of our performance metrics, all of which are more fully described in the accompanying proxy statement.

We remain pleased with our overall operating and financial performance, and we are confident that we are continuing to do all the things necessary to create value for our shareholders.

On behalf of our employees and the entire leadership team, we would like to thank you for your continued support of Unum.

This summary is intended to highlight certain key information contained in this proxy statement that, we believe, will assist you in reviewing the items of business to be voted on at the Annual Meeting. As it is only a summary, we encourage you to review the full proxy statement and our Annual Report on Form 10-K for more complete information about these topics.

Performance Highlights

Last year was another successful one for Unum as we continued to deliver solid operating results across much of the company, despite what remained a difficult economic environment. Especially challenging were persistently low interest rates which have hampered our investment returns. Highlights for 2012 include:(1)

— Pre-tax operating income of $1.24 billion and after-tax operating income of $887.5 million, based on operating revenue of $10.46 billion; — Operating earnings per share growth of 5.7% in 2012, the 7 th consecutive year of operating earnings per share growth, with a return on equity that has remained above the industry average; — Maintaining a solid investment portfolio and delivering strong investment results in spite of a low interest rate environment; — Repurchasing $500 million in stock and increasing dividends by approximately 24%; — Maintaining a strong capital position and receiving rating upgrades from two rating organizations during 2012; and — Growing our book value per share (ex-AOCI) by 12%. |  |

##### Table of Contents

Proxy Summary Information

Our total shareholder return (TSR) over the last five years outperformed our industry and Proxy Peer Group, which we believe is an indication of the strength of our business and financial plan. Our short-term return is less favorable, with a one-year TSR of 1.04%. We believe this is a result of a couple of factors. First, many of our peers experienced more significant declines during the financial crisis and may show greater year-over-year returns as they move back to pre-crisis levels. In addition, concerns regarding the low interest rate environment and business performance in a couple of areas also weighed on our share price performance. We continue to feel confident that the company’s history of solid operating results and returning value to shareholders will be recognized in the market – in fact, we are encouraged by the stock performance during the first quarter of 2013.

(1) | In analyzing performance, the company sometimes uses non-GAAP financial measures that differ from what is reported under GAAP. Refer to Appendix C for reconciliations of the non-GAAP financial measures used in this proxy summary, including operating income, operating revenue, operating earnings per share, return on equity and book value per share (excluding accumulated other comprehensive income, or AOCI), to the most directly comparable GAAP measures.

Compensation Highlights

Our compensation plans are tightly connected and leveraged to performance so even a small shortfall to plan has an impact. On an aggregate basis, the total plan payout for all employees was 6.9% below last year, resulting in compensation payments of $61.2 million versus the $66.4 million paid in 2011. The following table shows named executive officer compensation for 2012 performance and how it changed since last year. The table differs from the Summary Compensation Table on page 63, which includes pay elements that did not directly relate to 2012 performance and therefore were not taken into consideration by the Human Capital Committee as it made its 2012 compensation decisions. The table therefore:

| — |  | Excludes the actuarial increase of the present value of pension benefits; and

| — |  | Replaces the long-term incentive awards granted in 2012 (based on 2011 performance) with the awards granted in 2013 (based on 2012 performance).

2012 AND 2011 TOTAL COMPENSATION |  |  |  |  |  |  |  |
Executive |  | Performance Year |  | Salary |  | Annual Incentive |  | Long-Term Incentive |  | All Other Compensation |  | Total |  | Year Over Year Change
Mr. Watjen |  | 2012 |  | $1,100,000 |  | $1,489,125 |  | $5,462,499 |  | $89,164 |  | $8,140,788 |  |

(1) | The long-term incentive targets for Messrs. McKenney and McCarthy were increased in early 2012 based on consideration of market data from the appropriate comparator group as well as each individual’s target relative to other named executive officers, given their respective levels of responsibility. Assuming the 2011 targets had been in place in 2012, Messrs. McKenney’s and McCarthy’s year-over-year change would have been –7.6% and –6.1% respectively.

Response to 2012 Say-on-Pay Vote

Last year’s advisory vote on executive compensation (or “say-on-pay” vote) passed with 71% approval, which was lower than the previous year’s vote. Although 10 of our 11 largest shareholders supported the say-on-pay vote, the Human Capital Committee and management initiated a review of our executive compensation program. We held discussions with proxy advisory firms as well as many of our institutional investors, and considered specific suggestions for enhancing our compensation plan and related disclosures.

Based on this feedback, the Committee has taken or authorized the following principal actions to be taken in 2013 to better align the interests of shareholders and executives:

| — |  | Established new performance goals for our long-term incentive plan to reduce overlap with the performance goals for our annual incentive plan;

| — |  | Introduced performance share units (“PSUs”) based on three-year, prospective average return on equity and average earnings per share goals, with a modifier tied to relative total shareholder return;

| ¡ |  | PSU awards were made to the chief executive officer in 2013 and will be implemented for senior vice presidents and above, including our other named executive officers, beginning in 2014;

| — |  | Enhanced proxy disclosure to provide a more detailed explanation of the rationale behind compensation decisions and a more comprehensive discussion of goals, individual performance and the linkage to compensation; and

| — |  | Supplemented disclosure of our annual and long-term incentive performance metrics by including threshold, maximum and actual performance levels for each metric.

Information About the Board of Directors

Director Compensation

The Human Capital Committee reviews director compensation annually and makes recommendations to the Board as appropriate. Directors who are also employees of the company, such as Mr. Watjen, receive no additional compensation for services as directors of the company or any of its subsidiaries.

Benchmarking

With the assistance of its third-party compensation consultant, Pay Governance LLC, the Committee reviews peer group data to understand market practices for director compensation. Our non-employee director compensation is compared to that of companies in two peer groups: (1) the Proxy Peer Group described on page 39 of the Compensation Discussion and Analysis; and (2) a general industry peer group with market capitalizations ranging from $2 billion to $12 billion, which consisted of 201 companies for the review in December 2012. The Committee uses the approximate median of these peer groups as a reference point for setting director compensation. The use of two peer groups provides an indication of director pay levels both within the insurance industry as well as the broader market.

In December 2012, the Committee’s consultant provided its annual analysis of non-employee director compensation. While the analysis showed that total non-employee director compensation was approximately 5-14% below market median of the two comparator groups, the Committee decided not to make any change to non-employee director compensation.

For information about fees paid to Pay Governance LLC for director and executive officer compensation consulting services, see page 38 of the Compensation Discussion and Analysis.

Elements of Non-Employee Director Compensation

Non-employee directors receive cash retainers and equity awards as outlined in the following table:

CASH AND EQUITY COMPENSATION TO NON-EMPLOYEE DIRECTORS
All Directors: |  | Value
Annual cash retainer |  | $80,000
Annual restricted stock unit award |  | 120,000
Committee Chairs: |  |
Additional annual cash retainer - Audit Committee |  | 15,000
Additional annual cash retainer - all other Board committees |  | 10,000
Board Chairman: |  |
Additional annual cash retainer (paid quarterly) |  | 160,000

These amounts are prorated for partial-year service and may be deferred at the election of each director for payment in common stock at a future date. Directors deferring cash compensation receive a number of deferred share rights (each representing the right to one share of common stock) equal to the number of whole shares of common stock that could be purchased for the deferred amount based on the closing price of a share of common stock on the date the cash compensation is payable.

Directors’ expenses associated with attending Board and committee meetings, or other meetings relating to company business, are paid by the company. Directors are eligible to participate in our employee

Director Stock Ownership and Retention Guidelines

Each non-employee director is expected to own Unum securities with an aggregate value in excess of five times the director’s annual cash retainer (or $400,000). Prior to last year’s annual meeting of shareholders, the ownership goal was three times the director’s annual cash retainer (or $240,000). Directors who continued service on the Board following last year’s annual meeting have until May 24, 2014 to meet the increased goal (and until that time they are expected to continue to meet the prior goal), while new directors have five years from the date of their election.

Each non-employee director is also expected to retain Unum securities received as a result of director compensation for at least three years from the time the securities vest, and to retain at least the number of securities necessary to meet his or her ownership goal until retirement from the Board.

The Committee annually reviews each director’s stock ownership level. If a director does not reach his or her ownership goal in a timely manner, the Committee will determine whether action is appropriate. As of December 31, 2012, nine of our non-employee directors had met the increased ownership goal. The other two non-employee directors are expected to meet the increased ownership goal within the time period provided for reaching the goal.

Corporate Governance Guidelines

The Board of Directors has adopted corporate governance guidelines on a number of significant matters, including director selection and independence, director responsibilities, Board leadership and management succession. The corporate governance guidelines are available on our website at www.unum.com by clicking “Investors” and then “Corporate Governance.” The Governance Committee regularly reviews developments in corporate governance and recommends updates to the corporate governance guidelines and other documents as necessary or appropriate in response to regulatory requirements and evolving practices.

Board Leadership Structure

William J. Ryan, an independent director, serves as Chairman of the Board, and Thomas R. Watjen serves as Chief Executive Officer (CEO). The Board has determined that separation of the Chairman and CEO positions is appropriate at this time because it enables the CEO to devote the significant time and focus necessary to manage our business in the current environment. Our corporate governance guidelines allow the Board to combine the offices of Chairman and CEO when appropriate.

As an independent Chairman, Mr. Ryan is deemed the lead independent director. As such, he presides over executive sessions of the independent directors, facilitates information flow between directors and senior management, consults with the CEO and senior management about schedules, agendas and participants for Board meetings, and performs other duties specified in our corporate governance guidelines. If a non-independent director becomes Chairman, the Board will elect an independent director annually to serve as the lead independent director.

Our independent directors generally meet in executive session at each regularly scheduled Board meeting. Executive sessions enable the independent directors to discuss matters without management present, including management performance, succession planning and Board effectiveness. The independent directors met five times in executive session during 2012.

Director Independence

Our corporate governance guidelines provide that a substantial majority of the Board will be independent. For a director to be considered independent, the Board must determine that the director has no material relationship with our company, and the director must meet the requirements for independence under the listing standards of the New York Stock Exchange (“NYSE”). The Board has also determined that certain categories of relationships are not considered to be material relationships that would impair a director’s independence. These independence standards are listed in our corporate governance guidelines, which are available on our website at www.unum.com by clicking “Investors” and then “Corporate Governance.” In making independence determinations, the Board considers all relevant facts and circumstances.

The Governance Committee reviews information about the directors’ relationships and affiliations that might affect their independence and makes recommendations to the Board as to the independence of the directors.

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 23

##### Table of Contents

Corporate Governance

Based on a review of the findings and recommendations of the Governance Committee and applying the standards described above, the Board has determined that each of our directors is independent, with the exception of Thomas R. Watjen, our President and CEO.

Process for Nominating Directors

The Governance Committee is responsible for identifying and evaluating director candidates and recommending to the Board a slate of nominees for election at each annual meeting of shareholders. The Committee has retained a third party search firm to assist with recruitment efforts in preparation for upcoming retirements. This firm identifies candidates who meet the criteria of our search, provides requested background and other relevant information regarding candidates, and coordinates arrangements for interviews as necessary. Nominees may also be suggested by directors, management or shareholders.

Shareholders who wish to nominate director candidates must submit written notice of their nominations to the Corporate Secretary at Unum Group, 1 Fountain Square, Chattanooga, Tennessee 37402 in accordance with the process described on page 98 in the section titled “Shareholder proposals and nominations for our 2014 annual meeting.” Our policy is to consider candidates recommended by shareholders in the same manner as other candidates.

As specified in our corporate governance guidelines, the following criteria are used in evaluating the candidacy of a prospective nominee:

| — |  | Reputation for high ethical conduct, integrity, sound judgment and accountability;

| — |  | Current knowledge and experience in one or more core competencies;

| — |  | Ability to commit sufficient time to the Board and its committees;

| — |  | Collegial effectiveness; and

| — |  | Diversity, whether in viewpoints, gender, ethnic background, age, professional experience or other demographics (though no specific diversity policy is applied).

The core competencies sought in any particular candidate depend on the current and future needs of the Board based on an assessment of the composition of the Board and the mix of attributes and qualifications represented. Core competencies include knowledge and experience in finance, investments and accounting, executive management, the insurance or financial services industry, risk oversight, technology, marketing, strategic planning, regulatory compliance and public policy.

In addition to the criteria described above, the Governance Committee considers other specific qualifications that may be desired or required of nominees, including their independence and ability to satisfy Audit Committee or Human Capital Committee requirements. In determining whether to recommend a director for re-election, the Governance Committee also considers the director’s interest in continuing to serve, past attendance at meetings, contributions to the Board and committees on which the director serves, and the results of the most recent Board, committee and individual director evaluations.

The Board’s Role in Risk Oversight

The Board has an active role, as a whole and also at the committee level, in overseeing management of the company’s 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. The Board receives an enterprise risk management report at least annually, and usually more frequently. The Audit Committee is responsible for oversight of the company’s risk management process, financial risk, operational risk and any other risk not specifically assigned to another committee. A report on the company’s risk and risk management is provided to the Audit Committee at least quarterly. The Finance Committee is responsible for oversight of risks associated with investments and related financial matters, including those pertaining to our closed block segment. 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 enterprise risk management with respect to these risks. The

Corporate Governance

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.

Compensation Risk

Our enterprise risk management department, in consultation with the Human Capital Committee, has undertaken a risk assessment of our compensation programs and practices. The process included the following steps:

| — |  | Review the overall design and philosophy of the incentive compensation programs;

| — |  | Review and assess the 2012 annual incentive program and long-term incentive program performance measures for alignment between actual results and achievement payout levels;

| — |  | Identify fundamental principles to test, including the SEC’s non-exclusive list of situations where compensation programs may have the potential to raise material risks to the company; and

| — |  | Assess the incentive programs in light of the company’s primary risks (as disclosed in the company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012) and the company’s annual financial and capital plans; and

| — |  | Assess the effect of any proposed design changes to the 2013 incentive plans.

Based on this assessment, the following conclusions were reached:

| — |  | The company’s incentive program targets, thresholds, caps, weights and payout curves are effective control mechanisms.

| — |  | The incentive plans are balanced and align the long-term interests of stakeholders and management.

| — |  | The program’s goals are effectively balanced and consistent with the risk levels embedded in the company’s financial and capital plans.

| — |  | All potential awards are subject to Human Capital Committee discretion and the company has a recoupment policy in place in the event of a material earnings restatement.

Our enterprise risk management department and the Human Capital Committee do not believe the company’s compensation programs create risks that are reasonably likely to have a material adverse effect on the company.

Director Retirement Policy

Our bylaws state that no person may serve as a member of the Board beyond the date of the annual meeting of shareholders immediately following his or her 72 nd birthday.

Compensation Committee Interlocks and Insider Participation

During fiscal 2012, none of the members of the Human Capital Committee was an officer or employee of the company, and none of our executive officers served as a member of a board of directors or

compensation committee of any other entity that has one or more executive officers serving as a member of our Board or Human Capital Committee.

Related Party Transactions and Policy

The Board has adopted a written policy concerning related party transactions. This policy covers any transaction in which the company was or is to be a participant and the amount involved exceeds $120,000, and in which any related party had or will have a direct or indirect material interest. A “related party” means any of our directors, director nominees or executive officers, any of their immediate family members, any person known to us to beneficially own more than 5% of our outstanding common stock, and any entity in which any of these persons has an interest as an employee, principal or 10% or greater beneficial owner or other material financial interest.

Prior to entering into a transaction that may be viewed as a related party transaction, the related party must notify our general counsel of the facts and circumstances of the transaction. If the general counsel determines that the proposed transaction is a related party transaction, it is submitted to the disinterested members of the Audit Committee for consideration at the next Committee meeting (or to the chair of the Committee if it is not practical to wait until the next meeting and the chair is not a related party to the transaction). The Committee considers all relevant facts and circumstances, including the benefits to the company, benefits to the related party, and if the related party is an independent director or nominee, the potential effect of entering into the transaction on the director’s or nominee’s independence, any improper conflict of interest that may exist, the availability of other sources for the products and services, the terms of the transaction, and the terms available from or to unrelated third parties generally.

The transaction may be approved if it is determined in good faith not to be inconsistent with the best interests of the company and shareholders. Certain types of transactions are deemed to be pre-approved by the Audit Committee, including executive officer and director compensation arrangements approved by the Board of Directors or the Human Capital Committee and any transaction between the company and any entity in which a related party has a relationship solely as a director, less than 10% equity holder, or employee (other than executive officer), or all of these relationships.

Transactions with Related Persons

During 2012 and up to the date of this proxy statement, there have been no related party transactions, other than those described above as being deemed pre-approved.

Codes of Conduct and Ethics

The Board has adopted a code of conduct establishing certain business practices and ethics applicable to all of our directors, officers and employees. The Board has also adopted a separate code of ethics applicable to our CEO and certain of our senior financial officers. Both of these codes are available on our website at www.unum.com by clicking “Investors” and then “Corporate Conduct and Ethics.”

We will provide notice of any waivers of the code of conduct granted to executive officers or directors on our website, and will report to the SEC any waivers of the code of ethics granted to our CEO or certain of our senior financial officers. No waivers have been requested or granted to date, and no requests for waivers are anticipated.

Among other responsibilities described elsewhere in this report, the Committee reviews and discusses matters relating to the company’s financial and accounting reporting processes; reviews and discusses with management and the independent auditor the company’s annual and quarterly financial statements and related disclosures in reports filed with the SEC; pre-approves all audit services and permitted non-audit services to be performed by the company’s independent auditor; reviews and, as appropriate, discusses with management and the independent auditor the responsibilities and performance of the internal audit function, including audit findings and management responses; reviews and discusses with management the adequacy and effectiveness of the company’s risk management program; and obtains and reviews reports concerning the company’s policies and procedures for ensuring compliance with applicable laws, regulations and the company’s Code of Conduct.

Management is primarily responsible for the preparation, presentation and integrity of the company’s financial statements and for the reporting process, including the establishment and effectiveness of the company’s internal control over financial reporting. The company’s independent auditor, Ernst & Young LLP, is responsible for performing an independent audit of the financial statements and expressing an opinion on whether they conform to generally accepted accounting principles. The independent auditor also is responsible for auditing the effectiveness of the company’s internal control over financial reporting. The independent auditor reports directly to the Committee, which is responsible for the appointment, compensation, retention and oversight of the work performed by the independent auditor.

In fulfilling its oversight responsibilities, the Committee reviewed and discussed with management the company’s audited financial statements for the year ended December 31, 2012, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. The Committee reviewed with the independent auditor its judgments of the quality and acceptability of the company’s accounting principles. The Committee discussed with the independent auditor the matters required to be discussed by the Statement on Auditing Standard No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T. The Committee received the written disclosures and the letter from the independent auditor required by applicable requirements of the PCAOB regarding the auditor’s communications with the Committee concerning independence. The Committee also discussed with the independent auditor matters relating to its independence, including consideration of whether the independent auditor’s provision of non-audit services to the company is compatible with the auditor’s independence.

Report of the Audit Committee

The Committee discussed with the company’s internal auditors and independent auditor, and received regular status reports from them concerning, the overall scope and plans for their respective audits. The Committee met with the internal auditors and independent auditor, with and without management present, to discuss the results of their examinations, their evaluations of the effectiveness of the company’s internal control over financial reporting and the overall quality of the company’s financial reporting.

In evaluating the performance of the company’s independent auditor, the Committee took into consideration a number of factors, including the professional qualifications of the firm and the lead audit partner, the quality and candor of the firm’s communications with the Committee and the company, and evidence supporting the firm’s independence, objectivity, and professional skepticism. Based on this evaluation, the Committee appointed Ernst & Young LLP as the company’s independent auditor for 2013. Although the Committee has sole authority to appoint the independent auditor, the Committee recommended that the Board of Directors seek shareholder ratification of the appointment at the Annual Meeting.

Based on the reviews and discussions referred to above, the Committee recommended to the Board of Directors, and the Board approved, that the company’s audited financial statements for the year ended December 31, 2012 be included in the company’s Annual Report on Form 10-K for filing with the Securities and Exchange Commission.

Business and Performance Review

Our Business

We are a leading provider of financial protection benefits in the United States and United Kingdom. Our products, which are primarily offered through the workplace, include disability, life, accident and critical illness insurance and help protect millions of working people and their families from the financial hardships that can occur in the event of illness, injury or loss of life. In 2012, we paid more than $6 billion in benefits to hundreds of thousands of customers who faced illness, injury or loss of life.

Our business operations are divided into three divisions selling active products – Unum US, Unum UK and Colonial Life – and a closed block of business that includes products we service and support but no longer actively sell.

2012 Performance

Overall, 2012 was another successful year for Unum as we continued to deliver solid operating results for our shareholders. We faced a number of external challenges in 2012 as low interest rates continued to hamper our investment returns and the sluggish economic environment pressured our top-line growth. In spite of these and other ongoing challenges, we grew the businesses we targeted for growth, generated solid profitability in our core businesses and maintained a solid financial foundation.

Among the highlights for the year(1):

— — — — — |  | We reported pre-tax operating income of $1.24 billion and after-tax operating income of $887.5 million on operating revenues of $10.46 billion and operating earnings per share of $3.15, a 5.7% increase and the 7 th consecutive year of operating earnings per share growth. Overall, premiums, which include our Closed Block segment, grew 2.7% year-over-year. Premium in the markets we targeted for growth grew 4.7% in 2012, capping more than two years of steadily improving trends in this area. We continued to deliver strong investment results and, through our emphasis on sound risk management, our credit quality remains among the best in the insurance industry. We continued to generate a return on equity above the industry average with our active businesses delivering a return of 14.12% and total company ROE of 12.26%. Additionally, our brand strengthened, as we maintained strong customer and claimant satisfaction ratings, corporate image and reputation reached its highest level ever, and our visibility among public policy makers grew as we took a more active role in promoting the importance of financial protection benefits offered through the workplace. |  |  |  |

We maintained a strong balance sheet and capital position which closed the year near the high end of all of our capital related targets. We repurchased $500 million in stock and increased our dividend by about 24%. Since early 2008, we have repurchased approximately $2.2 billion of our shares and increased dividend paid per common share by 73%. Our consistent operating results and financial position led to ratings upgrades by both S&P and Moody’s during the year. Our book value per share (ex-AOCI) grew 12% to $29.55 at the end of 2012. |  |  |  |

Business Segment Highlights

Within the specific business areas, performance was as follows:

Our Unum US segment, representing 57.8% of our consolidated premium income in 2012, reported record operating income in 2012 with a 3.7% increase driven by growth in premium income and strong risk results and expense management. Premium income increased 3.7% in 2012, despite the challenging economy and competitive environment, and sales increased 7.5%, with growth in each of our product lines and in each of our major market segments. Unum US continued to generate above-market returns across all of its primary business segments, with a return on equity of 13.80%.

Compensation Discussion and Analysis

Unum UK, representing 9.0% of our consolidated premium income in 2012, reported a decrease in operating income of 31.1% in 2012, due primarily to adverse risk results in the group life product line. Premium income grew 2.2% while Unum UK sales decreased 6.1%, primarily driven by lower group life sales as the company took actions to address profitability concerns in this line of business. The Unum UK return on equity for 2012 was 12.22%.

Colonial Life, representing 15.4% of our consolidated premium income in 2012, reported record operating income with a 1.6% increase in 2012. Premium income grew 5.2% in 2012 while sales decreased 1.1% in the year. Consistent with past years, Colonial Life continues to generate solid margins and returns, with a return on equity of 16.75%.

Our investment results remain solid, although our net investment income declined slightly in 2012, primarily due to a decline in yield on invested assets as we continue to invest new cash flows at lower rates. Our asset quality remains strong, with a net unrealized gain on our fixed maturity securities of $7.2 billion at December 31, 2012, compared to $5.8 billion at December 31, 2011.

Total Shareholder Return

We continue to manage the business to create long-term value for our shareholders. As referenced earlier, while underlying business performance in 2012 was strong, the company’s stock performance was below that of its peers. Our total shareholder return (TSR) over the last five years outperformed our industry and Proxy Peer Group, which we believe is an indication of the strength of our business and financial plan. Our short-term return is less favorable, with a one-year TSR of 1.04%. We believe this is a result of a couple of factors. First, many companies in Unum’s peer group had more significant declines during the financial and economic crisis and may show greater year-over-year returns as they move back to pre-crisis levels. In addition, concerns regarding the low interest rate environment and business performance in a couple of areas also weighed on our share price performance. We continue to feel confident that the company’s history of solid operating results and returning value to shareholders will be recognized in the market – in fact, we are encouraged by the stock performance during the first quarter of 2013.

Compensation Discussion and Analysis

Response to 2012 Say-on-Pay Vote

At our 2012 annual meeting of shareholders, the advisory vote on executive compensation passed by a vote of 71%, which was lower than the previous year’s vote. Although 10 of our 11 largest shareholders supported the say-on-pay vote, the Committee and management initiated a review of our executive compensation program. We evaluated the reports of proxy advisory firms as well as feedback from our outreach program to institutional investors.

Based on this feedback, the Committee has taken or authorized the following principal actions to be taken in 2013 to better align the interests of shareholders and executives:

| — |  | Established new performance goals for our long-term incentive plan to reduce overlap with the performance goals for our annual incentive plan;

| — |  | Introduced performance share units (“PSUs”) based on three-year, prospective average return on equity and average earnings per share goals, with a modifier tied to relative total shareholder return (see “2012 Decisions on Compensation Design” beginning on page 49);

| ¡ |  | PSU awards were made to the CEO in 2013 and will be implemented for senior vice presidents and above, including our other NEOs, beginning in 2014;

| — |  | Enhanced proxy disclosure to provide a more detailed explanation of the rationale behind compensation decisions and a more comprehensive discussion of goals, individual performance and the linkage to compensation; and

| — |  | Supplemented disclosure of our annual and long-term incentive performance metrics by including threshold, maximum and actual performance levels for each metric (see “Performance Targets” beginning on page 44).

The Committee and the Board have carefully evaluated our executive compensation program and the feedback received from our shareholders, and believe the above actions appropriately respond to shareholders on these important issues.

Compensation Program Structure and Decisions

Our executive compensation philosophy is designed to reward performance that helps us achieve our corporate objectives and attract and retain talented individuals. We do this by:

| — |  | Offering a base salary that reflects the competitive market as well as the roles, skills, abilities, experience and performance of employees;

| — |  | Providing incentive opportunities for all employees based on the achievement of corporate and individual performance goals; and

| — |  | Aligning the long-term interests of management and shareholders by offering performance-based equity compensation opportunities and requiring senior executive officers to own shares and retain equity awards for a specified period of time after vesting. This practice also promotes a culture of ownership and accountability in the company.

Compensation Discussion and Analysis

Elements of Pay

There are five primary elements of pay in our executive compensation program, which are summarized in the table below.

Those pay elements that are “at risk,” or contingent on individual or corporate performance are noted in the table below. Our NEOs, as the most senior officers in the company, have a majority of their total compensation at risk. For 2012, 85.4% of Mr. Watjen’s compensation was at risk. For the remaining NEOs, 71.3% of their aggregate compensation was at risk.

PAY ELEMENTS |  |
Compensation Element |  | Objective/Purpose
Annual base salary |  | To provide a fixed amount of compensation which is reflective of the market for similar jobs as well as individual skills, abilities and performance. Aligns with our compensation philosophy of attracting and retaining talented individuals.
Annual incentive awards (at risk) |  | To motivate executives to achieve short-term corporate financial goals as well as individual objectives. Aligns with our compensation philosophy of rewarding performance in the achievement of short-term corporate objectives.
Long-term incentive awards (at risk) |  | To motivate long-term performance and align the interests of management and shareholders. Aligns with our compensation philosophy of rewarding long-term performance and attracting and retaining talented individuals.
Retirement and workplace benefits |  | To provide a competitive program which addresses health, welfare and retirement needs of executives and other employees. Aligns with our compensation philosophy of attracting and retaining talented individuals.
Perquisites and other personal benefits |  | Most perquisites were eliminated as of January 1, 2008. The limited perquisites we currently offer are in support of a specific business purpose or a contractual arrangement.

Roles of the Committee, CEO and Consultants

The Committee, CEO and compensation consultant each have important roles in our compensation program. The Committee, with input from the CEO and compensation consultant, exercises its own independent judgment to:

| — |  | Evaluate, design and administer a compensation program for executive officers that appropriately links pay, company and individual performance, and the creation of shareholder value;

| — |  | Review the performance of the CEO, with input from the full Board, and determine his compensation; and

| — |  | Determine compensation for each of the other NEOs.

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 37

##### Table of Contents

Compensation Discussion and Analysis

The CEO provides input to the Committee on compensation issues but does not participate in any decisions related to his own compensation. He provides to the Committee:

| — |  | A self-assessment outlining his own performance for the year;

| — |  | Performance assessments and compensation recommendations for executives who report to him, which includes all of the NEOs; and

| — |  | His perspective on the business environment and the company’s performance.

Pay Governance LLC was retained by the Committee as its compensation consultant in 2012 to provide objective, expert analyses, independent advice and information on executive and director compensation. A senior representative of the compensation consultant generally attends Committee meetings, participates in executive sessions of the Committee without management present and communicates directly with Committee members outside of meetings. Management interacts with the compensation consultant only when doing so on behalf of the Committee or as it relates to proposals the Committee will review for approval.

The Committee has adopted a policy requiring that its compensation consultant be independent. During 2012, the Committee assessed the independence of Pay Governance LLC, taking into account the following factors:

| — |  | Compliance with the Committee’s independence policy;

| — |  | Other services, if any, provided to the company by the consultant;

| — |  | The amount of fees paid by the company to the consultant as a percentage of its total revenues;

| — |  | Any business or personal relationships between the consultant (including its representatives) and the company’s directors or senior officers; and

| — |  | The policies and procedures the consultant has in place to prevent conflicts of interest, which includes a prohibition against stock ownership in the company.

Pay Governance LLC has attested to its independence and does not provide any services to the company other than those related to director and executive compensation consulting. Fees paid to Pay Governance LLC for such services provided in 2012 totaled $260,047. Based on its assessment, the Committee concluded that the compensation consultant is independent under the Committee’s policy and that the compensation consultant’s work has not raised any conflict of interest.

In addition, the company’s finance, human resources and legal staff, including the chief financial officer and the general counsel, support the Committee in its work. Employees from these departments discuss various executive compensation topics with the Committee and its compensation consultant, including how compensation plans fit in with other programs and business objectives. Although these staff members may make recommendations, the final decision on all executive compensation matters rests solely with the Committee.

Compensation Benchmarking

The Committee compares the compensation of our named executive officers to the median pay of executives in similar positions at peer companies. By targeting each element to the approximate median of the appropriate comparator group, we ensure that the balance among the elements is competitive, while at the same time allowing company and individual performance to determine a majority of the compensation received by our NEOs. Overall, these benchmarking comparisons are used as points of reference and are secondary to the primary factors considered by the Committee when making

38 | Notice of Annual Meeting of Shareholders and 2013 Proxy Statement

##### Table of Contents

Compensation Discussion and Analysis

compensation decisions: company performance; individual performance; the executive’s level of responsibility; the creation of shareholder value; our executive compensation philosophy; and the results of the most recent shareholder say-on-pay vote.

The two sources used by the Committee for benchmarking executive compensation are:

| — |  | For CEO and CFO compensation, a proxy peer group comprised of insurance and financial services companies that are either our business competitors or primary competitors for talent (“Proxy Peer Group”). This group is also a reference for compensation programs and practices. The composition of this group is reviewed annually by the Committee.

| — |  | For the compensation of our other NEOs, the Towers Watson Diversified Insurance Study of Executive Compensation (“Diversified Insurance Study”). This source is used because responsibilities of our NEOs may not be directly comparable with those of named executives at other companies in the Proxy Peer Group.

As part of its review of the Proxy Peer Group in 2012, the Committee requested detailed analysis to understand how sensitive compensation is to the size of companies within the peer group. The two largest and two smallest peers (as defined by their average ranking within the peer group on assets, market capitalization and revenues) were excluded. Regression analysis showed that (1) excluding these peers would have no impact on the compensation medians or Unum’s relative ranking within the group, (2) there was a low correlation between asset size and CEO compensation and, (3) though more closely correlated to CEO compensation, market capitalization can be a volatile measure, which could imply greater year-over-year variability in compensation than is actually occurring in the market. Based on the analysis, the Committee decided to make no changes to the Proxy Peer Group. Unum continues to approximate the median of peer assets, market capitalization and revenue.

The following table lists the companies in the Proxy Peer Group and the Diversified Insurance Study.

PROXY PEER GROUP(1)(2) |  |  |  | DIVERSIFIED INSURANCE STUDY(1)
Aetna |  | Lincoln Financial |  |  |  | Aegon USA |  | Massachusetts Mutual
Aflac |  | Marsh & McLennan |  |  |  | Aflac |  | Metlife

|  |  |  |  |  | ING |  | Thrivent Financial
|  |  |  |  |  | John Hancock |  | TIAA-CREFF
|  |  |  |  |  | Lincoln Financial |  | USAA

(1) | For compensation decisions made in early 2012, benchmarking comparisons were made to the 2011 Diversified Insurance Study of Executive Compensation and the 2011 Proxy Peer Group. Although Unum participates in the Diversified Insurance Study, we are excluded from this table. CNO Financial was a new participant in the DIS Survey for 2011, increasing the number of participants from 28 in 2010 to 29 in 2011.

(2) | The Proxy Peer Group includes both property and casualty insurers and life and health insurers, with Unum being slightly above the peer median for assets and slightly below the peer median for revenue for the year ended December 31, 2011. Unum is not part of the Proxy Peer Group.

Individual Performance Assessments

The Committee uses individual performance assessments as a factor in its determination of compensation for each NEO. Individual performance is measured against the six leadership criteria listed in the table below and can be used to adjust earned awards between 0% and 125%.

Evaluation Criteria

In evaluating how effectively each NEO met the leadership criteria, the Committee considers:

| — |  | Company performance;

| — |  | The CEO’s performance assessments of the other NEOs. For each individual, this includes a self assessment and a “360 evaluation” of performance by a combination of the CEO, peers, direct reports and other partners; and

| — |  | A Board assessment of each NEO against stated goals in the areas listed in the table below.

LEADERSHIP CRITERIA |  | BOARD ASSESSMENT GOAL AREAS
Delivers results |  | Strategic planning
Builds organizational talent |  | Demonstrated performance
Makes effective decisions |  | Building and sustaining a high-functioning organization and team
Creates business and enterprise value |  | Humility and ego maturity

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 41

##### Table of Contents

Compensation Discussion and Analysis

Individual performance highlights for each NEO, and their awarded performance percentage, are included below:

Thomas R. Watjen, President and CEO

In assessing Mr. Watjen’s performance for 2012, the Committee noted that he:

| — |  | Achieved most of the company’s business and financial objectives, the exceptions being in Unum UK and the Closed Block, which did not meet their objectives for the year.

| — |  | Maintained a strong balance sheet and capital position which has lead to rating upgrades and allowed the company to once again this year raise its dividend and repurchase a meaningful amount of stock to consistently create value for shareholders.

| — |  | Made significant progress in strengthening and deepening the leadership team throughout the company.

| — |  | Continued to develop the company culture and values at all levels, including ethics and compliance, risk management and social responsibility, while also enhancing the image and reputation of the company.

Given these accomplishments, the Committee awarded Mr. Watjen an individual performance percentage of 95% for his annual incentive award and 115% for his long-term incentive award. The Committee awarded a greater percentage in Mr. Watjen’s long-term incentive award based on the factors noted above as well as Mr. Watjen’s decision-making and strategic positioning of the company. The ratings are lower this year primarily because of the shortfall in performance in Unum UK and the Closed Block. However, the Committee noted how quickly Mr. Watjen addressed business areas that were underperforming.

Richard P. McKenney, CFO

In assessing Mr. McKenney’s performance for 2012, the Committee noted that he:

| — |  | Achieved most of the company’s financial, operational, and organizational objectives, the exceptions being in Unum UK and the Closed Block, which did not meet their objectives for the year.

| — |  | Effectively balanced operating and financial goals while maintaining a strong capital base that positions the company well for the longer term and also positions it to regularly return capital to shareholders through dividend increases and repurchasing its shares.

| — |  | Further developed talent, both within the finance organization as well as across the enterprise.

| — |  | Broadened his operational knowledge and deepened his connections within the businesses, and, as a result, he has continued to contribute at a very high level.

Given these accomplishments, the Committee awarded Mr. McKenney an individual performance percentage of 110% for his annual incentive award and 120% for his long-term incentive award. The Committee awarded a greater percentage in Mr. McKenney’s long-term incentive award based on the factors noted above as well as his disciplined assessment of corporate development opportunities, strong capital management strategy, the investment performance in a difficult environment and the overall strength of the investment portfolio. His annual incentive is slightly lower than last year because of the underperformance in Unum UK and the Closed Block.

Kevin P. McCarthy, COO and President and CEO of Unum US

In assessing Mr. McCarthy’s performance for 2012, the Committee noted that he:

| — |  | Led Unum US to another solid year with strong performance in nearly all financial and operational areas. Unum US enjoyed record before-tax operating income in 2012.

| — |  | In his role as chief operating officer and chair of the company operating committee, made significant contributions across the company.

| — |  | Continued to take an active role in developing talent throughout the company and assuring that we are better utilizing our talent at all levels around the company.

| — |  | Through the company operating committee has enhanced operating effectiveness by adopting process improvements, sharing best practices, and creating centers of excellence.

Given these accomplishments, the Committee awarded Mr. McCarthy an individual performance percentage of 120% for his annual incentive award and 125% for his long-term incentive award. The Committee awarded a greater percentage in Mr. McCarthy’s long-term incentive award based on the additional consideration of his leadership role in exporting talent across the company and the strategic guidance he provided. His annual incentive is slightly lower than last year because of underperformance in the Closed Block.

Randall C. Horn, President and CEO of Colonial Life

In assessing Mr. Horn’s performance for 2012, the Committee noted that he:

| — |  | Led Colonial Life to solid financial results, generally achieving its objectives including strong margins and returns on equity; the one exception was sales growth, which was below expectations.

| — |  | Continued to deliver exceptional service results and customer retention of business at Colonial Life, resulting in strong premium growth for the year.

| — |  | Strengthened his leadership team and made significant progress developing talent throughout the organization.

| — |  | Contributed to improvements throughout the company through his role on the company operating committee, which has led to the implementation of several centers of excellence initiatives at Colonial Life.

Given these accomplishments, the Committee awarded Mr. Horn an individual performance percentage of 90% for both his annual and long-term incentive awards. This was slightly lower than last year primarily due to the sales shortfall.

Liston Bishop III, Executive Vice President and General Counsel

In assessing Mr. Bishop’s performance for 2012, the Committee noted that he:

| — |  | Made significant progress redefining the corporate law department to better support business requirements.

| — |  | Provided important guidance and counsel to the Board, the CEO, and the executive leadership team.

| — |  | Set a strong tone at the top on important issues such as ethics, compliance, corporate governance, and customer privacy protection.

| — |  | Worked across the businesses to positively impact hiring, organizational issues, and professional development in areas critical to our legal, compliance, and audit functions.

Given these accomplishments, the Committee awarded Mr. Bishop an individual performance percentage of 100% for both his annual and long-term incentive awards. These levels are consistent with those of last year.

Performance Targets

Each year, the Committee sets targets for several performance measures that are used to calculate annual and long-term incentive awards. Performance measures and their respective targets are established for the company as a whole as well as for each of our business units, and weightings are assigned to each performance measure based on its relative importance to the company or business unit.

Incentive Funding Performance Requirement

Our annual and long-term incentive plans are not funded unless the company achieves a specified level of performance. We apply an incentive funding performance requirement because we believe employees and officers should receive incentive awards only after our shareholders and creditors are paid. Additionally, the company expects that meeting this incentive funding performance requirement will allow the company to deduct the incentive payments under Section 162(m) of the Internal Revenue Code.

For 2012, the performance requirement established by the Committee to fund the annual and long-term incentive plans was $433 million, or two times the sum of dividends to shareholders and after-tax interest expense on recourse debt. Funds used to attain the performance requirement were derived from statutory after-tax operating earnings and other sources of cash flow available from the company’s insurance and non-insurance subsidiaries. The company successfully achieved the 2012 performance requirement for funding the annual and long-term incentive plans.

Annual Incentive Targets

The Committee established performance targets as part of our annual incentive program. The following table outlines these targets for annual incentives awarded for 2012 performance and how the company performed against those targets in 2012.

(5) | Before-tax operating income is defined as net income adjusted to exclude net realized investment gains or losses, non-operating retirement-related gains or losses, and income tax.

(6) | Service is based on the average of several service metrics for policyholders, producers and claimants.

(7) | Net investment income reflects the impact of investment results on after-tax operating income. Net investment income excludes interest on policy loans, investment income on floating rate securities backing floating rate debt, investment income on index-linked securities which support claim reserves that provide for index-linked claim payments, variances to plan for asset levels and specified portions of miscellaneous net investment income, and includes investment income related to investments managed by Unum supporting reserves related to a block of individual disability business assumed through a modified coinsurance agreement.

(8) | Avoided losses is calculated by multiplying an industry standard weighted default rate by Unum’s total credit exposure and comparing to Unum’s actual investment losses.

(9) | Market composite consists of comparing the average of three targets: (1) credit spreads on purchases to a specified benchmark, (2) yields on purchases to a specified benchmark, and (3) realized investment losses to a specified peer group.

Each performance target has been selected because the Committee believes it is an appropriate driver of long-term shareholder value:

| — |  | The growth and competitiveness of the company are measured using sales, earned premium and revenue targets;

| — |  | Profitability achievement is measured using after-tax operating income for Unum Group and pre-tax operating income for Unum US, Colonial Life and Unum UK;

| — |  | Capital management effectiveness is measured using return on equity; and

| — |  | Effective and efficient customer service is measured using the service and operating expense ratio targets.

A business area performance composite measure is also included in our annual incentive targets to better align our corporate staff functions, which provide support to each of our business units, with the results generated in those units.

Depending on their role in the company, our NEOs’ annual incentive awards are tied in various ways to the performance of Unum Group and its business units. The annual incentive awards of Messrs. Watjen, McKenney and Bishop are based entirely on Unum Group performance. For Mr. McCarthy, given the change in his role in early 2012, 50% of his award is based on Unum Group performance and 50% is based on Unum US performance. For Mr. Horn, 25% of his award is based on Unum Group performance and 75% is based on Colonial Life performance.

Long-Term Incentive Targets

Consistent with the disclosure we have provided in prior years, the grant of long-term incentive is not actually made until after the performance for a particular year is evaluated. For example, the performance share units, performance-based restricted stock units and stock options for 2012 performance were granted in 2013. This means that the amounts reported in the Summary Compensation table on page 63 are for 2011 performance and the most recent Committee decisions and long-term incentive awards based on performance in 2012 will be reported in the Summary Compensation table of next year’s proxy statement. For this reason, we include the targets for both of these awards in the tables below and the award calculations for both years are outlined in the Long-Term Incentive Awards section beginning on page 53.

Compensation Discussion and Analysis

The Committee established performance targets as part of our long-term incentive program. The following table outlines these targets for long-term incentives awarded in 2013 (for 2012 performance), how each target represents a driver of shareholder value and how the company performed against those targets:

2013 LONG-TERM INCENTIVE FOR 2012 PERFORMANCE AWARD TARGETS ($s in millions)
Corporate Performance Factors |  | Driver of |  | Component |  |  |  |  |  |  |  |
Unum Group |  | Shareholder Value |  | Weighting |  | Threshold |  | Target |  | Maximum |  | Actual

As discussed above, the long-term incentive awards reported in the Summary Compensation Table on page 63 were decisions that the Committee made in February 2012, based on performance during 2011. The following table outlines the targets for 2011 and how each represents a driver of shareholder value.

2012 LONG-TERM INCENTIVE FOR 2011 PERFORMANCE AWARD TARGETS ($s in millions)
Corporate Performance Factors |  | Driver of |  | Component |  |

After-tax operating earnings(1) |  | Profitability |  | 40% |  | $897.9
Return on equity(1) |  | Capital Management Effectiveness |  | 40% |  | 10.87%
Operating Revenue |  | Long-Term Growth |  | 20% |  | $10,226.3

(1) | As reported in our 2012 proxy statement, for long-term incentives awarded in 2012 for 2011 performance, the Committee excluded the impact of the following items not included in the 2011 financial plan:

| (a) | The variance in foreign currency exchange rates from those assumed in the 2011 financial plan;

| (b) | The after-tax charge of $561.2 million as a result of the company’s completion of its strategic review of its long-term care business;

| (c) | The after-tax charge of $119.3 million to strengthen reserves in the individual disability closed block;

| (d) | An income tax benefit of $41.3 million due to a final settlement with the IRS with respect to our appeal of audit adjustments for the tax years 1996 to 2004; and

| (e) | An income tax charge of $18.6 million related to the repatriation of £150.0 million of dividends from our U.K. subsidiaries

The Committee believes these performance targets represent long-term drivers of shareholder value:

| — |  | Value creation is measured on the basis of growth, profitability and effective capital management;

| — |  | Long-term growth is measured using overall company revenue as the target; and

| — |  | Capital management effectiveness is measured using return on equity.

For our long-term incentive program, all of our NEOs’ awards are based entirely on the long-term performance targets of Unum Group.

Items Excluded from Determining Company Performance

When setting the performance measures and weightings for 2012, the Committee determined that certain items not included in the 2012 financial plan would be excluded from the calculation of the company’s performance for the purposes of both the annual and long-term incentive plans should they occur. These items were:

| — |  | Unplanned adjustments resulting from accounting policy changes, legal or regulatory rule or law changes;

| — |  | The impact of any unplanned acquisitions, divestitures, or block reinsurance transactions;

| — |  | Unplanned adjustments to the closed block of business;

| — |  | The effect of any unplanned regulatory, legal or tax settlements;

| — |  | The effect of unplanned changes to strategic asset allocation;

| — |  | Unplanned debt issuance, repurchasing or retirement; or stock repurchase or issuance;

| — |  | The effect of differences between actual currency exchange rates versus exchange rates assumed in the financial plan;

| — |  | Unplanned fees or assessments, including tax assessments, from new legislation; and

| — |  | The effect on revenue from unplanned variances from floating rate securities and index-linked securities.

The Committee adjusted targets for the impact of the following items on our 2012 financial results that were not included in the 2012 financial plan from which the targets were initially derived:

| — |  | Unplanned debt issuance;

| — |  | The effect of differences between actual foreign currency exchange rates versus exchange rates assumed in the financial plan; and

| — |  | The effect on revenue from unplanned variances from floating rate securities and index-linked securities.

In addition, 2012 targets have been adjusted to align with our reporting of after-tax operating income. In 2012, the company modified its reporting to exclude net periodic benefit costs for pensions and other postretirement benefit plans which the company considers to be non-operating. This change was made after the adoption of plan targets by the Committee and had an insignificant impact on plan achievements.

Each year, the Committee undertakes an overall assessment of the results while also maintaining the discretion to make final pool adjustments within the total dollars available. Any adjustments are based on a review of the actual achievement for each performance measure compared to the targets listed on pages 45 and 47, as well as a qualitative assessment of results. For 2012, the Committee made small adjustments to each business unit’s performance which slightly reduced the aggregate payout. These adjustments were based on several factors including: the impact of Unum UK’s before-tax operating income results on the company’s overall performance, and moving to more consistent service metrics across the company. The resulting plan achievement levels were as follows:

Compensation Decisions

2012 Decisions on Incentive Compensation Design

During 2012, in response to the say-on-pay voting results and specific feedback from our shareholders, management and the Committee conducted a review of our executive compensation program. The following key principles were part of the review:

| — |  | Changes should be adopted for executives with responsibility for setting and delivering Unum’s business strategy;

| — |  | Sustained or growing equity ownership among our executives continues to be a key objective;

| — |  | The long-term incentive plan should be keyed to long-term financial goals that drive shareholder value; and

| — |  | Total shareholder return as measured against competitors for capital should be a factor in the final long-term incentive earned.

Incentive Program Changes

As a result of this review, the Committee decided to reduce overlap among performance goal measures for our annual and long-term incentive plans. Average earnings per share and average return on equity performance measures, each weighted equally, were established for the long-term incentive plan. These goals were selected because they are considered drivers of long-term shareholder value. Although a small amount of overlap remains since the annual incentive plan includes a return on equity performance measure (weighted at 20%), the Committee believes that this overlap is appropriate.

The Committee also decided to change the mix of the long-term incentive awards for senior vice presidents and above, which includes the NEOs, transitioning to a mix of 50% performance share units (“PSUs”) and 50% performance-based restricted stock units (“PBRSUs”). The senior vice presidents currently receive 100% PBRSUs while the named executive officers and other executive vice presidents receive 75% PBRSUs and 25% stock options. The new mix of 50% PSUs and 50% PBRSUs is aligned with the practices of our Proxy Peer Group and meets the key principles defined by the Committee. The

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 49

##### Table of Contents

Compensation Discussion and Analysis

PSUs will vest based on the achievement of three-year, prospective average earnings per share and average return on equity goals, and achievement will be modified (+/- 20%) based on Unum’s total shareholder return relative to ten members of our Proxy Peer Group. These ten companies (Aflac, Assurant, Hartford Financial, Lincoln Financial, MetLife, Principal Financial, Protective Life, Prudential Financial, Stancorp and Torchmark) were selected because they are considered to be direct business competitors of Unum. The PBRSUs will vest ratably over three years.

As a result of the move to PSUs with vesting based on prospective three-year goals, beginning in 2014 we will no longer use a one-year corporate performance multiplier in calculating the amount of the long-term incentive award to be divided among PSUs and PBRSUs. However, because the long-term incentive plan must be funded before an award may be granted and funding is contingent upon achieving a performance requirement, as described on page 44, we believe all long-term incentive awards will continue to be performance-based.

For the February 2013 grant, the Committee decided to operate the long-term incentive plan as a hybrid, changing the mix of the CEO’s award to 50% PBRSUs and 50% PSUs but continuing to use the corporate performance multiplier (based on 2012 performance) to determine the grant amount. For the remaining executives, the change in mix was communicated in early 2013 with implementation to be phased in for the awards in 2014 and 2015. This will allow participants time to adjust to and plan for the change and offsets a portion of the reduction in cash flow as a result of this change (i.e., moving from annual ratable vesting to three-year cliff vesting). For all NEOs other than the CEO, the mix of their 2013 long-term incentive awards continued to be 75% PBRSUs and 25% stock options.

Performance Contingent Adjustments to CEO Incentive Targets

In February 2012, the Committee increased Mr. Watjen’s annual incentive target to 200% of salary from 150% and his long-term incentive target to $6 million from $5 million to better align with competitive levels. This was reported in our 2012 proxy statement. After the filing of our proxy, the Committee received feedback suggesting that there should be a more direct link between Mr. Watjen’s 2012 incentive targets and shareholder return. In May 2012, the Committee, with Mr. Watjen’s full support, added an additional performance condition to the application of the new incentive targets. The increases to Mr. Watjen’s annual and long-term incentive targets for 2012 performance would only be applied if both the company’s 1- and 3-year total shareholder returns (TSRs) for the periods ending on December 31, 2012 exceeded the medians of the comparable 1- and 3-year TSRs of our Proxy Peer Group. The company fell short of these goals for 2012; therefore, the increased targets were not applied in calculating Mr. Watjen’s incentive compensation as outlined on pages 53 and 55.

On the following page is a graphical representation of how Mr. Watjen’s annual and long-term incentive awards in 2013 were calculated. The awards included performance hurdles which had to be met for an award of either annual or long-term incentive to be made, additional hurdles to determine his annual and long-term incentive targets and a third set of hurdles to determine the size of the long-term incentive grant. Additionally, for the 50% which was paid in PSUs, there are additional hurdles (i.e., three-year goals with a TSR modifier) which will determine the amount of vesting, if any.

Annual Base Salary

Salaries for our NEOs are established based on their position, skills, experience, responsibility and performance. Competitiveness of salary levels is assessed annually relative to the approximate median of salaries in the marketplace for similar executive positions. Increases may be considered for factors such as changes in responsibilities, individual performance and/or changes in the competitive marketplace.

At its February 2012 meeting, the Committee approved several changes to base salary for NEOs. In making these adjustments, the Committee considered market data, individual performance, responsibilities and tenure for each NEO. Along with input from the CEO, the Committee approved the following base salaries with any increase noted in parentheses. Effective March 1, 2012: Mr. Watjen

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 51

$1,100,000 (no change); Mr. McKenney $681,500 (2.5%); Mr. Horn $492,500 (1.5%) and Mr. Bishop $414,500 (1.5%). On January 1, 2012, Mr. McCarthy assumed the additional responsibilities of chief operating officer and received an increase in base salary to $615,000 (5.1%), which included a merit increase.

At its February 2013 meeting, the Committee approved the following changes to base salary for NEOs, effective March 1, 2013: Mr. Watjen $1,122,000 (2.0%); Mr. McKenney $700,000 (2.7%); Mr. McCarthy $630,000 (2.4%); Mr. Horn $500,000 (1.5%) and Mr. Bishop $421,000 (1.6%). These adjustments were made after consideration of company and individual performance during 2012, each executive’s responsibilities and tenure, and market data.

Annual Incentive Awards

Our annual incentive awards reward performance based on the achievement of both company and individual performance, which the Committee believes aligns compensation with the objectives of shareholders. The Management Incentive Compensation Plan of 2008, under which 2012 annual incentive awards were granted, includes:

| — |  | Eligibility for all non-sales employees to receive an annual incentive;

| — |  | An Executive Officer Incentive Plan in which our NEOs participate; and

| — |  | A process for the Committee to establish an objective performance measure at the beginning of each year that provides funding for incentive payments. This goal must be achieved before participants are eligible to receive an award. If the goal is not achieved, the plan is not funded.

The decision making process to determine annual incentive awards is as follows:

(1) | The Committee exercises discretion as to the final percentage considering all performance factors, including, but not limited to, the quality of financial results. For details on adjustments for 2012, see page 48.

(2) | Individual performance may range from 0% to 125%.

Once the performance threshold is met, specific awards for our NEOs are arrived at by:

| — |  | Determining individual annual incentive targets, which are set as a percentage of each individual’s base salary. In establishing the target, the Committee considers market data from the appropriate peer group as well as each individual’s target relative to other NEOs, given their respective levels of responsibility;

Compensation Discussion and Analysis

| — |  | Calculating company and business unit performance percentages by comparing actual results to the performance targets listed on page 45. The Committee may also take into account other factors, including economic considerations as well as non-financial goals;

| — |  | Establishing an individual performance percentage (from 0% to 125%) via the individual assessment process described beginning on page 40; and

| — |  | Multiplying company and business unit performance by individual performance and the NEO’s annual incentive target. The maximum award that an individual may receive under our plan is $8 million.

The table below describes the annual incentive awards made by the Committee to our NEOs for 2012 performance.

(1) | Company performance for Messrs. Watjen, McKenney and Bishop was based on Unum Group achievement of 95%.

(2) | Company performance for Mr. McCarthy was weighted with 50% based on Unum US and 50% based on Unum Group performance. Unum US achievement was 105% and Unum Group achievement was 95%, which when weighted, resulted in an achievement of 100%.

(3) | Company performance for Mr. Horn was weighted with 75% based on Colonial Life and 25% based on Unum Group performance. Colonial Life achievement was 95% and Unum Group achievement was 95%, which when weighted, resulted in an achievement of 95%.

In addition to determining the annual incentive awards shown above for 2012 performance, at its February 2013 meeting, the Committee set individual targets for 2013 annual incentive awards for each NEO. The targets were set based on consideration of each NEO’s current target, the approximate median of the comparison group and each individual’s target relative to other NEOs, given their respective levels of responsibility. Based on its review, the Committee did not make any changes to annual incentive targets for 2013.

Long-Term Incentive Awards

Our long-term incentive plan aligns the long-term interests of management and shareholders by tying a substantial portion of executive compensation directly to the company’s stock price. The awards, which are a combination of performance-based restricted stock units and performance share units for the CEO

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 53

##### Table of Contents

Compensation Discussion and Analysis

and a combination of stock options and performance-based restricted stock units for the other NEOs, are granted under the Stock Incentive Plan of 2012. Our long-term incentive award mix is based on a review of peer practices and ensures that a portion of each executive’s compensation is tied to the increase of our stock price over the long term.

Performance-based restricted stock units, which are valued in terms of company stock, do not include any actual stock issued at the time of grant. Instead, company stock is issued only when the grant is settled. During the restricted period, dividends are not paid in the form of cash but rather as additional restricted stock units. In addition, there are no shareholder voting rights unless and until the award is settled in shares.

Performance share units are notional units that will track the value of Unum’s share price over the three-year performance period, and vest contingent upon the achievement of predetermined performance metrics.

As described under “Incentive Program Changes” beginning on page 49, for the February 2013 grant the Committee decided to operate the long-term incentive plan as a hybrid. The mix of the CEO’s award was changed to 50% PBRSUs and 50% PSUs, while other NEOs continued to receive 75% PBRSUs and 25% stock options. In addition, the corporate performance multiplier (based on 2012 performance) was used to determine the grant amount.

The decision-making process to determine long-term incentive awards is as follows:

(1) | The Committee exercises discretion as to the final percentage considering all performance factors, including, but not limited to, the quality of financial results. For details on adjustments for 2012, see page 48.

(2) | Individual performance may range from 0% to 125%.

As outlined in the diagram above, once the performance threshold is met, the awards for our NEOs were determined by:

| — |  | Determining individual long-term incentive targets for each NEO, which are set at the beginning of each year, by considering the market data from the appropriate comparator group as well as each individual’s target relative to other NEOs, given their respective levels of responsibility. The long-term incentive targets are set as a dollar amount for Mr. Watjen and as a percentage of base salary for other NEOs;

| — |  | Calculating company and business unit performance percentages by comparing actual results to the performance targets listed on page 47. The Committee may also take into account other factors, including economic considerations as well as non-financial goals;

| — |  | Multiplying company and business unit performance by individual performance and the NEO’s long-term incentive target. The maximum award that each NEO could receive for 2012 was 300% of target.

Once the award value was determined, it was delivered as described below:

| — |  | The CEO’s award is divided evenly between performance-based restricted stock units (50%) and performance share units (50%);

| — |  | The awards for all other NEOs are granted as 75% performance-based restricted stock units and 25% stock options; and

| — |  | The performance-based restricted stock unit and stock option awards vest based on the NEOs continued service over a three-year period. The CEO’s performance share units vest dependent upon three year goals for return on equity and earnings per share, modified by relative total shareholder return as described above.

Based on 2012 performance, the Committee approved grants of performance-based restricted stock units, performance share units and stock options, as applicable, for the NEOs as outlined below.

Compensation Discussion and Analysis

Of the 50% portion of Mr. Watjen’s long-term incentive award that was paid in performance-based restricted stock units, 50% will be settled in stock and 50% will be settled in cash upon vesting. This change was made in February 2010 by the Committee to reflect the fact that Mr. Watjen had a very significant ownership position in the company and it was in the best interest of the company to reduce the amount of additional equity issued.

(3) | The long-term incentive targets for Messrs. McKenney and McCarthy were increased in early 2012 based on consideration of market data from the appropriate comparator group as well as each individual’s target relative to other NEOs, given their respective levels of responsibility. The Committee increased their targets from 150% to 200%. Assuming the same targets had been in place in 2012, Messrs. McKenney’s and McCarthy’s year-over-year change would have been –7.6% and –6.1% respectively.

The long-term incentive awards reported in the Summary Compensation Table on page 63 were decisions that the Committee made in February 2012, based on performance during 2011. The Committee used the same process described above in determining these awards. They were calculated as shown in the table below.

Of the 75% portion of Mr. Watjen’s long-term incentive award that was paid in performance-based restricted stock units, 50% will be settled in stock and 50% will be settled in cash upon vesting.

The Committee set individual long-term incentive targets for 2013 at the February meeting for each NEO. These targets did not change from the 2012 targets. This includes the target for Mr. Watjen which will remain at $5 million unless both the company’s 1-year and 3-year total shareholder returns (TSRs) for the periods ending on December 31, 2013 exceed the respective medians of the comparable 1-year and 3-year TSRs of the company’s Proxy Peer Group. If both the 1-year and 3-year TSRs exceed the respective proxy peer group medians, Mr. Watjen’s long-term incentive target will be $6 million.

Retirement and Workplace Benefits

We provide a benefits package for employees, including all NEOs, and their dependents, portions of which are paid for, in whole or in part, by the employee.

Among the retirement benefits we offer are:

| — |  | Pension plans. We sponsor a tax-qualified, defined benefit pension plan, and for employees whose benefits under the tax-qualified plans are limited by the Internal Revenue Service, a non-qualified pension plan. Base pay and annual incentives are counted toward the defined benefit pension plans, but long-term incentives are not. Since 2000, the CEO also has had a supplemental executive retirement plan under the terms of his employment agreement, and is the only active employee covered under the plan. For a complete description of pension benefits for our NEOs, see page 70.

| — |  | 401(k). We provide a tax-qualified 401(k) retirement plan for all regular US employees who are scheduled to work at least 1,000 hours per year. This plan provides funded, tax-qualified benefits up to the limits on compensation and benefits under the Internal Revenue Code. Unum provides up to a 4% company match for those employees who contribute to the plan and have completed one year of service.

The workplace benefits we offer include: life, health, dental, vision and disability insurance; dependent and healthcare reimbursement accounts; tuition reimbursement; an employee stock purchase plan; paid time off; holidays; and a matching gifts program for charitable contributions.

In April 2000, the company purchased corporate owned life insurance (COLI) on all officers who gave their approval. In the event of death while still employed, the company provides a death benefit to the officer’s beneficiary in the amount of $200,000. Of the NEOs, Messrs. Bishop, Horn and McKenney were not employees of the company at that time, and therefore are not covered under a COLI policy.

Perquisites and Other Personal Benefits

The company provides a limited number of perquisites, which are described below:

| — |  | A tax gross-up is provided for non-resident state taxes when any employee travels to other company locations outside of their primary state of employment and incurs state income tax based on another state’s law. Due to the frequency of travel between Unum’s corporate offices and other locations, NEOs often incur non-resident state taxes in multiple states.

| — |  | Use of the corporate aircraft for personal travel is provided to the CEO as part of company policy. As such, Mr. Watjen is entitled to a company paid benefit of up to 40 hours of personal use of the corporate aircraft. Since June 2009, Mr. Watjen has voluntarily elected to discontinue the company paid benefit. In addition, he has entered into a time-sharing agreement where he reimburses the company for the costs of the aircraft for personal use. He continues to use the time-sharing agreement to reimburse the company for all personal travel on the corporate aircraft. During 2012, he made payments to the company of $75,129 for 29.2 hours of personal usage. This amount has not been included in the Summary Compensation Table since there is no incremental cost to the company.

| — |  | A tax gross-up is provided to employees who incur income on company-sponsored events where attendance is expected. The company hosts a limited number of events each year to recognize the contributions of various employees. These functions serve specific business purposes and in

| some cases, the attendance of an NEO and his spouse or guest is expected. When this occurs, the company attributes income to the NEO for this when required under Internal Revenue Service regulations.

For more information, see the All Other Compensation table on page 64.

Executive Compensation Summary

The following Total Compensation table provides an overview of compensation awarded to our NEOs for both 2012 and 2011 performance. It differs from the Summary Compensation Table required by the Securities and Exchange Commission in several ways. Specifically, the Total Compensation table:

| — |  | Excludes the actuarial increase in the present value of pension benefits that is included in the Summary Compensation Table. This amount is not in the Committee’s control;

| — |  | Replaces the long-term incentive awards granted in 2012 based on 2011 performance with the awards granted in 2013 based on 2012 performance (see “Long-Term Incentive Awards” beginning on page 53 for additional details); and

| — |  | Includes the year-over-year change in total compensation from the Committee’s perspective in making compensation decisions.

The Total Compensation table is not a substitute for the required Summary Compensation Table found on page 64.

Compensation Discussion and Analysis

Compensation Contracts and Agreements

Unum has the following compensation contracts and agreements with NEOs.

Employment Agreements

Mr. Watjen is the only NEO covered under an employment agreement. The agreement currently extends through December 16, 2014, and is subject to automatic one-year extensions unless either party gives the required notice of its intention not to renew. Under the agreement, Mr. Watjen is entitled to the following compensation:

| — |  | Base salary of $1,100,000;

| — |  | Target annual incentive of no less than 150% of his base salary, excluding any special or supplemental bonuses that may be awarded;

| — |  | Eligibility for annual equity grants and/or cash-based awards as determined by the Committee;

| — |  | Participation in all saving, retirement, health and welfare benefit programs generally available to our other senior executive officers;

| — |  | Minimum annual retirement benefit equal to 2.5% of his final average earnings multiplied by his years of service up to 20 years;

| — |  | Post-retirement welfare benefit coverage for a period of three years following the date of termination; and

| — |  | A lump-sum payment representing the increase in present value of his retirement benefit as if he had accumulated three additional years of age and service.

The agreement further stipulates that Mr. Watjen would be prohibited from using or divulging confidential information and from competing with us or soliciting any officer at the level of vice president or above for a period of 18 months after his termination. These non-competition and non-solicitation covenants would be terminated upon a change in control.

Mr. Watjen also entered into an aircraft time-sharing agreement with the company in 2007. Details about that agreement can be found on page 57.

Severance Benefits

The company provides severance benefits to all employees in the event of involuntary termination, other than for death, disability or cause. Mr. Watjen’s severance benefits are provided under his employment agreement and are outlined beginning on page 74. The remaining NEOs are covered under our Separation Pay Plan for Executive Vice Presidents. In general, we provide severance in order to give our employees competitive benefits with respect to the possibility of an involuntary termination of their employment.

When termination of employment is accompanied by severance payments, the former executive is required to release all claims he or she may have against the company. The release contains restrictions on the former executive with respect to confidentiality, solicitation of company employees, competition, and disparagement. The company also agrees to indemnify the former executive for certain actions taken on behalf of the company during his or her employment.

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 59

##### Table of Contents

Compensation Discussion and Analysis

Change in Control Agreements

Each of the NEOs, other than Mr. Watjen, is covered by a change in control agreement with the company. These agreements provide an enhanced severance benefit in the event of a termination following a change in control. This ensures that shareholders have the benefit of our NEOs’ focused attention during the critical time before and after a major corporate transaction despite the uncertainty with respect to their future employment. These benefits are defined for Mr. Watjen under his employment agreement and for the other NEOs in Change in Control Severance Agreements.

Details about these agreements can be found in the “Terminations Related to a Change in Control” section beginning on page 74.

While these agreements include a modified excise tax gross-up provision, the company decided in May 2010 not to enter into any new or materially amended agreements with executive officers for excise tax gross-up provisions with respect to payments contingent upon a change in control.

Compensation Policies and Practices

Unum has a number of compensation policies and stated practices with respect to compensation. These are detailed in this section.

Equity Grant Practices

Equity grants awarded under the long-term incentive program are approved at the February meeting of the Committee, which typically occurs 2-3 weeks after the company’s annual earnings are released to the public. The date the equity grant is approved is considered the grant date and is also the date upon which the stock price is based.

Stock Ownership and Retention Requirements

Ensuring that senior executives have a significant ownership stake in the company aligns the long-term interests of management and shareholders and promotes a culture of ownership. We require certain senior executives including each NEO to:

| — |  | Hold a multiple of the executive’s base salary in Unum shares throughout employment; and

| — |  | Retain a fixed percentage of the net shares (shares after tax withholding) received as compensation for a specified period of time. These retention requirements apply to shares acquired upon the exercise of options and the vesting of performance-based restricted stock units and performance share units. Exceptions to this requirement may be made only by the Board of Directors.

The following table presents Unum’s stock ownership and retention guidelines for our NEOs. Newly promoted or newly hired executives have five years to achieve the ownership guidelines. Not meeting the guidelines may impact future equity grants. All of our NEOs exceeded the guidelines as of December 31, 2012.

Performance-based restricted stock units will vest over the next three years (see the Vesting Schedule for Unvested Restricted Stock Units table on page 69 for vesting schedule).

(3) | Retention percentage is the net percentage of shares to be held after the payment of taxes. Retention requirements apply to shares acquired upon the exercise of options and the vesting of performance-based restricted stock units and performance share units.

(4) | After this holding period, the executive would then be able to sell the shares as long as his ownership guideline is met or would be reached in the time period allotted.

Hedging and Insider Trading Policies

We have a policy that no director or executive officer, which includes our NEOs, may purchase or sell options, puts, calls, straddles, equity swaps or other derivatives that are directly linked to Unum stock.

In addition, we have an insider trading policy, which prohibits each of our directors, executive officers (including NEOs) and employees from buying or selling Unum stock while in possession of material nonpublic information about the company and from conveying any such information to others. Under this policy, additional trading restrictions apply to our named executive officers and other “corporate insiders,” who are generally permitted to buy or sell Unum stock only during predetermined window periods following earnings announcements, and only after they have pre-cleared the transactions with our General Counsel or his designee. Also under this policy, no corporate insider may make “short sales” of Unum stock, and no director or executive officer may pledge Unum stock as security for a loan.

Recoupment Policy

If the company makes a material restatement of its financial results, then the Board will, to the extent permitted by applicable law, seek recoupment of performance-based compensation paid to certain senior officers if it determines that:

| — |  | The senior officer has committed or engaged in fraud or willful misconduct that resulted, either directly or indirectly, in the need to make such restatement; and

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 61

##### Table of Contents

Compensation Discussion and Analysis

| — |  | Such performance-based compensation paid or awarded to the senior officer would have been a lesser amount if calculated using the restated financial results.

The amount of performance-based compensation to be recouped will be determined by the Board after taking into account the relevant facts and circumstances. Performance-based compensation includes annual cash incentive awards, bonuses and all forms of equity compensation. The company’s right to recoup compensation is in addition to other remedies that may be available to us under applicable law.

The Dodd-Frank Act, which contemplates an expansion of the reach of recoupment policies, was enacted into law in July 2010. Once the Securities and Exchange Commission provides rules and administrative guidance on requirements of this legislation, the Committee will review the SEC rules and implement any necessary changes to our current recoupment policy at that time.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code places a limit of $1 million per year on the amount of deductible compensation paid all named executive officers other than the CFO, unless the compensation satisfies the “performance-based compensation” exception to Section 162(m).

The current annual incentive payout and long-term incentive grants are designed to be deductible under Section 162(m). From time to time, the Committee may pay compensation that is not deductible under Section 162(m) if it determines that paying such compensation is needed in order to attract, retain or provide incentive to our NEOs.

We account for stock-based payments under the requirements of ASC Topic 718. A complete discussion of the assumptions made as well as the financial impact of this type of compensation can be found in Notes 1 and 10 of the Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012. Each year, the company provides a report to the Committee of the expense for stock-based payments. Additionally, in the event the Committee is considering new equity-based compensation programs or changes to existing programs, the accounting implications of the program or change are presented and discussed as part of the decision process.

The Human Capital Committee has reviewed and discussed with management the Compensation Discussion and Analysis contained in this proxy statement. Based on such review and discussions, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference into the company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

##### Table of Contents

Compensation Tables

(1) | The above table includes pay elements that the Committee did not consider in making compensation decisions related to 2012 performance. For an overview of these differences, see the Executive Compensation Summary on page 58.

(2) | The grant date fair value of stock awards for performance-based restricted stock units on February 21, 2012 was calculated in accordance with FASB ASC Topic 718 as the number of units multiplied by the closing market price of $23.35 on the grant date. This amount represents 75% of the long-term incentive granted to each named executive for performance in 2011. For Mr. Watjen, this amount will be 50% stock settled and 50% cash settled upon vesting.

(3) | This amount represents 25% of the long-term incentive granted to each named executive on February 21, 2012 for performance in 2011. The weighted average grant date fair value of options granted during 2012, 2011 and 2010 calculated in accordance with FASB ASC Topic 718 was $9.78, $11.73 and $9.04, respectively. We estimated the fair value on the date of grant using the Black-Scholes valuation model. The assumptions used to estimate the fair value of the 2012, 2011 and 2010 grants are set forth in Note 10 of our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012.

(4) | Amounts reflect the annual incentive awards granted in February 2013 for performance in 2012. These are discussed in further detail beginning on page 52 under the Annual Incentive Awards heading.

(5) | The amounts shown reflect the actuarial increase in present value since December 31, 2011 of the named executive officer’s benefits under all pension plans established by the company. The amounts were determined using interest rate and mortality rate assumptions consistent with those set forth in Note 8 of our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012, except as otherwise provided in footnote 1 to the Pension Benefits table on page 72. The increase in the pension value of Mr. Watjen is based on an increase in his service and pay as well as changes in the actuarial pension assumptions, particularly the discount rate. Approximately $1.9 million of the increase (46%) was due solely to the reduction in the assumed discount rate. The amount reported for Mr. McCarthy also includes the amount of above-market interest that exceeds 120% of the applicable federal long-term rate prescribed under section 1274(d) of the Internal Revenue Code. During 2012, that amount was $2,312.

(6) | “All Other Compensation” amounts are included within the following table:

2012 ALL OTHER COMPENSATION |  |  |  |  |  |  |  |  |  |

Total All Other Compensation |  | $89,164 |  | $74,658 |  | $23,626 |  | $45,935 |  | $19,459

| (a) | The amounts shown in this row represent tax payments made by Unum on behalf of each named executive officer relating to other items in this table.

| (b) | Spouses or guests sometimes accompany the named executive officer at company business functions. When their attendance is expected, a gross up payment is provided. Where applicable, these payments have been included under “Tax Reimbursement Payments.” Additionally, when these trips included travel on the corporate aircraft, the incremental cost was calculated to determine amounts to be included. For purposes of compensation disclosure, the use of company aircraft is valued using an incremental cost that takes into account fuel costs, landing fees, parking, weather monitoring and maintenance fees per hour of flight. Crew travel expenses are included based on

| the actual amount incurred for a particular trip. Fixed costs that do not change based on usage, such as pilot salaries and depreciation of the aircraft, are excluded.

| (c) | Amounts represent matching gifts made on behalf of the named executive officer to qualified non-profit organizations and educational institutions. The Matching Gifts Program is available to all full-time employees and non-employee directors and will match eligible gifts from a minimum of $50 to an aggregate maximum gift of $7,500 per employee/non-employee director, per calendar year.

| (d) | Matching contributions under Unum’s 401(k) Retirement Plan are provided to all eligible employees participating in the plan as described on page 57. For each participant who contributed at least 5%, the company ensured the participant received the maximum company match of 4%.

| (e) | Many of our employees are required to travel to other company locations outside of their primary state of employment. While working in a state other than their primary state of employment, employees may be required to pay state income taxes to that state if days worked or earnings exceed an amount specified in state law. When this happens, we pay the state income tax on behalf of the employee and gross up the income amount for FICA and Medicare taxes.

(1) | These amounts reflect the threshold, target and maximum award under the annual incentive plan. The threshold is the minimum level, which is 25% of the amount shown in the Target column. Target amounts are based on the individuals’ earnings for 2012 and their annual incentive target. The maximum award is 200% of such target.

(2) | Messrs. Watjen’s, McCarthy’s and Bishop’s stock option and performance-based restricted stock unit grants are no longer subject to risk of forfeiture because they meet the age and years of service requirement for retirement eligibility. Messrs. Watjen’s, McCarthy’s and Bishop’s grants will continue to vest ratably over three years on each anniversary of the grant date. If Messrs. Watjen, McCarthy or Bishop were to retire, any unvested stock options and performance-based restricted stock units would vest immediately upon retirement and the performance-based restricted stock units would be distributed no sooner than six months after the retirement date per Internal Revenue Code Section 409A.

(3) | As described on page 50, Mr. Watjen’s target was determined based on whether both the company’s 1- and 3-year total shareholder returns (TSRs) for the periods ending on December 31, 2012 exceeded the medians of the comparable 1- and 3-year TSRs of our Proxy Peer Group. The company failed to attain these goals for 2012; therefore, his target is shown at $1,650,000 (150%) in the table above instead of $2,200,000 (200%).

(4) | This grant of performance-based restricted stock units was made on February 21, 2012 based on 2011 company and individual performance and vests ratably over three years. This award was granted under the Stock Incentive Plan of

Compensation Tables

| 2007. Details are provided in the Long-Term Incentive Granted in 2012 table on page 56. For Mr. Watjen, 50% of these shares will be stock settled and 50% will be cash settled upon vesting.

(5) | These options were granted on February 21, 2012 based on 2011 company and individual performance and vest ratably over three years. Details are provided in the Long-Term Incentive Granted in 2012 table on page 56.

(6) | The amount shown is the closing market price on February 21, 2012.

(7) | The grant date fair value of stock awards for performance-based restricted stock units on February 21, 2012 was calculated as the number of units multiplied by the closing market price of $23.35 on the grant date.

(8) | The grant date fair value of options granted on February 21, 2012 calculated in accordance with FASB ASC Topic 718 was $9.78. The fair value on the date of grant was estimated using the Black-Scholes valuation model. The following assumptions were used to value the 2012 grant:

| (a) | Expected volatility of 52%, based on our historical daily stock prices;

| (b) | Expected life of 6.0 years, based on historical average years to exercise;

| (c) | Expected dividend yield of 1.80%, based on the dividend rate at the date of grant; and

| (d) | Risk-free rate of 1.13%, based on the yield of treasury bonds at the date of grant.

Unum has provided for post-employment compensation in a number of ways. These are detailed in this section.

Pension Benefits

We maintain three defined benefit plans in the United States, as defined in the table below:

DEFINED BENEFIT PLANS |  |
Plan Name |  | Purpose
Unum Group Pension Plan (Qualified Plan) |  | Provides funded, tax-qualified benefits up to the limits on compensation and benefits under the Internal Revenue Code. The Qualified Plan was designed to provide tax-qualified pension benefits for most employees.
Unum Group Supplemental Pension Plan (Excess Plan) |  | Provides unfunded, non-qualified benefits for compensation that exceeds the IRS limits in the Qualified Plan.
Unum Group Senior Executive Retirement Plan (SERP) |  | Mr. Watjen is the only active employee covered. Provides unfunded, non-qualified benefits that are offset by benefits under the Qualified Plan and the Excess Plan. The SERP supplements the pension benefits that are provided under the Qualified and Excess

Plan Descriptions

Following are details of how each of our plan benefits is calculated. These formulas incorporate base pay received in each plan year during which the employee accrues credited service and payments received from the regular annual incentive plan and any field or sales compensation plans. Not included are other bonuses, long-term incentive awards, commissions, prize awards or allowances for incidentals.

Qualified Plan

In calculating the basic pension benefits in our Qualified Plan, three criteria are used:

QUALIFIED PLAN CRITERIA |  |
Criteria |  | Definition
Credited service |  | A measure of the time individuals are employed at the company. One year of credited service is granted for each plan year in which 1,000 hours of employment are completed.
Highest average earnings |  | The average of the highest 5 years of compensation (whether or not consecutive) during the last 10 years of employment.
Social Security covered compensation |  | The average of the taxable wage bases in effect for each calendar year during the 35-year period ending with the last day of the calendar year in which an employee attains or will attain his or her Social Security retirement age.

70 | Notice of Annual Meeting of Shareholders and 2013 Proxy Statement

##### Table of Contents

Post-Employment Compensation

The basic benefit is provided as an annual single life annuity and is calculated as follows:

(1) | Can range from 3%, if the sum of an employee’s age and years of credited service is less than 30, to 8%, if the sum equals or exceeds 95.

(2) | Equal to 9.0 for retirement at age 65 and increased by 0.2 for each whole year retirement occurs prior to age 65.

All benefits are indexed on the first day of each plan year following the participant’s date of termination using the National Average Wage rate of increase published by the Social Security Administration in the preceding year (minimum of 2.75% and maximum of 5%).

Benefits provided under the Qualified Plan are based on pensionable earnings (which are described below) up to a compensation limit of $250,000 under the Internal Revenue Code. In addition, benefits may not exceed $200,000 (payable as a single life annuity beginning at any age from 62 through Social Security Normal Retirement Age) under the Internal Revenue Code.

Excess Plan

The Excess Plan takes into account pension benefits outside of the current Qualified Plan and is calculated as follows:

Mr. McCarthy was a member of pension plans maintained by our predecessor company, UNUM Corporation, and accrues an additional benefit for his 21 years of service prior to 2000.

SERP

The SERP is provided as a single life annuity beginning on the first day of the month following retirement. The benefit is calculated as follows:

Mr. Watjen is presently the only NEO covered under the SERP. This coverage is required under the terms of his employment agreement.

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 71

##### Table of Contents

Post-Employment Compensation

Retirement Age

Participants in the pension plans outlined above are eligible to retire as early as age 55. Under the Qualified and Excess plans, participants may retire early at age 55 with 5 years of vesting service. However, if a participant begins receiving a benefit prior to the normal retirement age of 65, the normal retirement benefit will be reduced based on the applicable early reduction factors defined in the plan.

Under the SERP, Mr. Watjen is eligible for an unreduced pension at age 60, and the amount of his unreduced pension is shown in the Pension Benefits table below. If he terminates employment and commences his benefit prior to age 60, the single life annuity will be reduced by 5% per year.

Current Value of Pension Benefits

Pension benefits payable to each NEO are summarized in the following table:

PENSION BENEFITS |  |  |  |  |  |  |  |
Name |  | Plan Name |  | Number of Years of Credited Service (#) |  | Present Value of Accumulated Benefits ($)(1) |  | Payments During Last Fiscal Year ($)

| Excess |  |  |  | 4.25 |  |  |  |  | 252,000 |  |  |  |  | – |

(1) | The “Present Value of Accumulated Benefits” is based upon a measurement date of December 31, 2012. Accordingly, all calculations utilize credited service and pensionable earnings as of the same date. The results shown are estimates only and actual benefits will be based upon data, pay, service, form of benefit elected and age at the time of retirement. The primary assumptions used in the calculations are based on the measurement date ASC 715 assumptions. Specifically, the accumulated benefit value calculations utilize a rate of 4.50% to discount expected future plan benefit payments to the measurement date, an annual increase in Social Security Wage Base of 3.5% to index the Qualified and Excess Plan benefits from the measurement date to commencement date and a post commencement life expectancy assumption based upon the RP-2000 Combined Healthy Participant Mortality Table projected 5 years past the measurement date with Projection Scale AA. Other assumptions used in the calculations are based on our understanding of the disclosure regulations. In particular, participants are assumed to commence benefits at their unreduced retirement age in each of the plans: age 65 in the Qualified and Excess plans and age 60 in the SERP. Also, no turnover (e.g. death, disability, termination, retirement) is assumed prior to retirement age.

Lump sum distributions are only available under the plan to vested employees who have a present value of future pension benefits of $10,000 or less. None of the NEOs are eligible for lump sum distributions

from the Qualified or Excess plans, or the SERP. Based on current benefit levels, pension payouts for NEOs will be paid in the form of a monthly annuity.

Nonqualified Deferred Compensation

We do not have any active nonqualified programs that allow for deferrals of compensation by our NEOs. However, Mr. McCarthy does have balances under two inactive plans that did allow for deferrals of compensation. The last year that compensation deferrals occurred under the plans was 2000.

NONQUALIFIED DEFERRED COMPENSATION |  |  |  |  |

Mr. Bishop |  | – |  | – |  | – |  | – |  |  | – |

(1) | Mr. McCarthy has balances under two inactive deferred compensation plans. The first inactive plan (the former UNUM Corporation Deferred Compensation Plan) earned interest at a rate of 6.64%. The interest rate for this plan is set once each year at the rate which is equivalent to the interest rate Unum receives on the Unum America Consolidated Portfolio (consisting of bonds, commercial mortgage loans and preferred stocks). The amount of above-market interest that exceeds 120% of the rate prescribed under section 1274(d) of the Internal Revenue Code has been included in the Change in Pension Value & Nonqualified Deferred Compensation Earnings column of the Summary Compensation Table on page 63. The second inactive plan (a non-qualified 401(k) plan) includes 100% Unum stock to be paid out in cash. The change in market value and dividends earned is included in the Aggregate Earnings in Last FY amount. The value of the balance is included in the Aggregate Balance at Last FYE amounts.

Post-Employment Compensation

Other Post-Employment Payments

The discussion below outlines estimated benefits payable under company policy to NEOs under various termination scenarios.

The following terminology will be used throughout the discussion of various termination scenarios:

DEFINITIONS |  |
Terminology |  | Descriptions
Termination with cause |  | One of the following factors is present: the failure to substantially perform duties; the willful engagement in illegal conduct or gross misconduct harmful to the company; or the conviction of a felony (or plea of “guilty” or “no contest”).
Termination without cause |  | One of the following factors is present: poor performance, other than for misconduct or cause (as defined above); job elimination; job requalification; or the decision to fill the position with a different resource consistent with the direction of the company.
Resignation for good reason |  | One or more of the following events have preceded the resignation of the named executive officer: assignment to a position inconsistent with his existing position or any other action that diminishes such position; reduction of his base salary or annual incentive target; failure to continue any material employee benefit or compensation plan in which he participates; relocation to an office more than 50 miles from his current location.
Change in control |  | A change in control occurs when one of the following situations exist: (a) the incumbent directors cease to be a majority for two years; (b) an entity acquires 20% of our voting stock (30% in some instances); (c) we consummate certain transactions such as a merger or disposition of substantially all of our assets; or (d) shareholders approve a plan of liquidation or distribution.

In the event of any termination of employment, all named executive officers would receive benefits to which they are entitled, including unpaid base salary through the date of termination, accrued vacation, and accrued benefits under the retirement plan.

Terminations Related to a Change in Control

As outlined in the “Compensation Contracts and Agreements” section on page 59, Mr. Watjen has an employment agreement that specifically addresses post-employment payments, including a change in control. The remaining NEOs are covered by Change in Control Severance Agreements. In the event of termination upon the occurrence of a change in control, NEOs would receive the following benefits:

| — |  | Three times the sum of his annual base salary and the average annual incentive paid to him in the three years prior to the date of termination for Mr. Watjen; Two times base salary and annual incentive (the greater of the current year target or the prior year annual incentive paid) for the remaining NEOs.

| — |  | Prorated annual incentive through the date of termination of employment.

74 | Notice of Annual Meeting of Shareholders and 2013 Proxy Statement

##### Table of Contents

Post-Employment Compensation

| — |  | Lump sum payment representing the increase in present value of retirement benefit as if the executive had accumulated 3 additional years of age and service for Mr. Watjen; 2 additional years of age and service for the remaining NEOs.

| — |  | Health and welfare benefits for up to 3 years for Mr. Watjen; up to two years for the remaining NEOs.

| — |  | Payment of all deferred compensation.

| — |  | Outplacement services (20% of base salary, maximum of $50,000).

| — |  | Vesting of equity awards as follows:

| ¡ |  | Grants of performance-based restricted stock unit and stock option awards made before December 14, 2011 would vest upon the occurrence of a change in control event. Upon termination, the stock options would remain exercisable for 90 days from the termination date. For Messrs. Watjen, McCarthy and Bishop, who are retirement eligible under the plan, the options would remain exercisable for the earlier of the original expiration date or five years from the termination date.

| ¡ |  | Grants made on or after December 14, 2011 require the occurrence of both (1) a change in control event and (2) a termination of employment for any of the following reasons: death, disability, involuntary (without cause), or good reason in order for the performance-based restricted stock unit and stock option awards to vest. Upon termination, the stock options remain exercisable for 90 days from the termination date. For Messrs. Watjen, McCarthy and Bishop, who are retirement eligible under the plan, the options would remain exercisable as outlined above.

| — |  | In the event of a change in control and termination, the NEO may receive a reimbursement for any excise tax owed. If a reduction in the payments by no more than 10% would result in no excise tax being owed, the reduction will occur.

Terminations Not Related to a Change in Control

There are instances absent a change in control in which an NEO’s employment may be terminated. The company may terminate for cause or without cause. Additionally, termination of employment may occur upon an NEO’s voluntary resignation, retirement, becoming disabled or dying.

Messrs. Watjen, McCarthy and Bishop are eligible for retirement under the terms of the Stock Incentive Plans of 2007 and 2012. In the event of termination other than for cause, their unvested performance-based restricted stock unit awards would vest; stock option awards would vest and remain exercisable for the earlier of the original expiration date or five years from the termination date. However, to the extent necessary to avoid the imposition of penalty taxes under Internal Revenue Code Section 409A, stock would not be distributed until at least six months after the date of termination.

Also under these plans, in the event of death or disability of any participant (which includes the NEOs), performance-based restricted stock unit awards would vest and stock option awards would vest and remain exercisable for the earlier of the original expiration date or three years from the date of death or disability.

(1) | If Mr. Watjen is terminated without cause, or resigns with good reason, he will receive severance of three times the sum of his annual base salary and the average annual incentive paid to him in the three years prior to the date of termination. Other NEOs who are terminated without cause will receive eighteen months of base salary.

(2) | Annual incentive will be prorated through the date of termination of employment. In the event of retirement, an executive will be eligible for prorated annual incentive only if retirement is on or after the last business day in March.

(3) | If Mr. Watjen is terminated without cause or resigns with good reason, his unvested equity awards will accelerate vesting due to his eligibility for retirement under the plan as described above. His employment agreement also provides for the early vesting of equity. In the event of death, disability or retirement (if eligible), an executive’s unvested equity will be accelerated.

(4) | If Mr. Watjen is terminated without cause or resigns with good reason, he will receive health and welfare benefits for up to 3 years;

(5) | Outplacement services are equal to 20% of base salary (maximum of $50,000).

(6) | If Mr. Watjen is terminated without cause or resigns with good reason, he will receive a lump sum payment representing the increase in present value of his retirement benefit as if he had accumulated 3 additional years of age and service.

(7) | Monthly benefits from the company’s long-term disability plan until the earlier of age 65 or death.

(8) | Group life insurance benefits are $50,000 for each full-time employee; Corporate owned life insurance benefits as applicable (if Messrs. Watjen and McCarthy are active employees on the date of death, their respective beneficiaries as defined in the policy will receive $200,000).

Termination Payments

Termination payments are provided to NEOs as outlined in the following table and vary with the circumstances under which the termination occurs. In the event of termination as a result of death, payments will be made to the named executive officer’s beneficiary.

All termination scenarios in the table assume a termination date of December 31, 2012. Excluded are amounts received as an annuity under our retirement plans and the “in-the-money” value of vested

Post-Employment Compensation

(1) | In the event of job elimination, the prorated early vesting of equity awards would be as follows: Mr. McKenney $1,091,468 and Mr. Horn $484,669. Messrs. Watjen, McCarthy and Bishop are eligible for retirement status under the terms of the Stock Incentive Plan of 2007 and the Stock Incentive Plan of 2012. Therefore, they would receive full vesting as noted in the Retirement section of this table. The amounts represent the value of the shares at a market price of $20.82 (the closing price on December 31, 2012, the last trading day of the year).

(2) | Pension enhancement is a lump sum payment representing the increase in present value of retirement from three additional years of age and service credit for Mr. Watjen, and two additional years of age and service credit for the remaining named executive officers.

(3) | If any payments pursuant to Mr. Watjen’s employment agreement or the Change in Control Severance Agreements would be subject to any excise tax under Section 4999 of the Internal Revenue Code, the company will provide an additional payment such that the named executive officer will retain a net amount equal to the payments he would have retained if such excise tax had not applied. If the value of such payments (calculated in accordance with the IRS rules) exceeds the IRS limit by 10% or less, then the payments would be reduced to avoid the excise tax. The payments for each named executive officer would not exceed the IRS limit, and as a result, no excise tax would be triggered.

(4) | Messrs. Watjen, McCarthy and Bishop would be eligible for early vesting of equity under the terms of the Plan for retirement status. Messrs. McKenney and Horn did not meet the eligibility criteria of combination of age and years of service as of December 31, 2012.

Equity Compensation Plan Information

Below is a brief description of the equity compensation plans not approved by shareholders:

Unum Group Amended and Restated Non-Employee Director Compensation Plan of 2004

This plan provided for the payment of annual retainers and meeting fees (discontinued in May 2011) to the non-employee directors who served on our Board. Under the plan, directors made an irrevocable election each year to receive all or a portion of their retainers and meeting fees in either cash or deferred share rights. A deferred share right is a right to receive one share of common stock on the earlier of (i) the director’s separation from service as a director of our company, or (ii) another designated date at least three years after the date of the deferral election. The number of deferred share rights granted is calculated as the number of whole shares equal to (i) the dollar amount of the annual retainer and/or fees that the director elects to have paid in deferred share rights, divided by (ii) the fair market value per share on the grant date. The aggregate number of shares which can be issued under the plan is 500,000. This plan terminated in May 2010 with respect to new awards, though dividend equivalents remain available for future issuance in respect of awards that were outstanding at that time. The plan is administered by the Human Capital Committee. The plan includes provisions restricting the transferability of the deferred share rights, provisions for adjustments to the number of shares available for grants, and the number of shares subject to outstanding grants in the event of recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, or other similar corporate transaction. There are stock ownership guidelines for participants under the plan.

Under Section 16(a) of the Securities Exchange Act of 1934, our directors, executive officers, and 10% beneficial holders of our common stock are required to file with the Securities and Exchange Commission certain forms reporting their beneficial ownership of and transactions in our common stock. Based solely upon information provided by these persons, we believe each of our directors and executive officers and 10% beneficial owners filed all required reports on a timely basis during the last fiscal year.

Election of Directors

(Item 1 on the Proxy Card)

Our Board of Directors currently consists of 12 members equally divided among three classes, each with a three-year term. At the Annual Meeting, four directors are seeking election for terms expiring in 2016. As described in Item 2 below, we are also proposing to amend our certificate of incorporation to phase out the Board’s classified structure and provide for the annual election of all directors beginning in 2016.

Upon the recommendation of the Governance Committee, the Board of Directors has nominated E. Michael Caulfield, Ronald E. Goldsberry, Kevin T. Kabat and Michael J. Passarella for election as directors. Each nominee currently serves on the Board and has agreed to continue to serve if elected. The Board has no reason to believe that any nominee will be unable to serve if elected. However, if any nominee becomes unable or unwilling to serve before the Annual Meeting, proxies may be voted for another person nominated as a substitute by the Board, or the Board may reduce the number of directors. Information concerning these nominees is provided under the section titled “Nominees for Election as Directors with Terms Expiring in 2016” beginning on page 14.

The Board of Directors unanimously recommends that you vote FOR the election of each of the nominees for director: E. Michael Caulfield, Ronald E. Goldsberry, Kevin T. Kabat and Michael J. Passarella.

Adoption of Amended and Restated Certificate of Incorporation to Declassify the Board of Directors

(Item 2 on the Proxy Card)

Our certificate of incorporation currently divides the Board of Directors into three classes of directors serving staggered three-year terms. The Board recommends that you adopt an amended and restated certificate of incorporation to provide for the elimination of the classification of the Board over a three-year period beginning in 2014 and to make certain non-substantive changes to conform references to gender and the use of defined terms.

The text of the proposed amended and restated certificate of incorporation, marked to show the amendments, is set forth in Appendix A to this proxy statement, with deletions indicated by strike-outs and additions indicated by underlining. If adopted, we would promptly file the amended and restated certificate of incorporation with the Secretary of State of Delaware, at which time it will become effective.

##### Table of Contents

Items to Be Voted On

Reasons for the Proposed Amended and Restated Certificate of Incorporation

Upon the recommendation of the Governance Committee, the Board has determined that it is appropriate to propose declassification over a three-year period beginning in 2014. The Board believes that the existing classified structure provides many important benefits, including continuity and stability of leadership, enhanced independence of non-management directors, and time and leverage to explore alternatives and negotiate for enhanced shareholder value in the event of hostile change-in-control attempts. However, the Board acknowledges growing investor sentiment in favor of annual elections and believes the Board would continue to be effective in protecting shareholder interests under an annual election system. The Board recognizes that many investors believe that the election of directors is the primary means for shareholders to influence corporate governance policies and hold management accountable for implementing those policies. After balancing these interests, the Board has decided to recommend phased elimination of its classified structure.

Impact of the Proposed Amended and Restated Certificate of Incorporation

Phased Elimination of the Classified Board Structure

If the proposed amended and restated certificate of incorporation is adopted, beginning in 2014 each director elected at an annual meeting of our shareholders will be elected for a one-year term expiring at the following year’s annual meeting. This will result in all directors being elected on an annual basis beginning with our annual meeting in 2016, at which time the Board will cease to be classified. Approval of the amended and restated certificate of incorporation will not change the expected terms to which our directors were previously elected or appointed to the Board. Directors elected at this year’s Annual Meeting will serve for a three-year term expiring at our annual meeting in 2016, and directors currently serving terms that expire in 2014 and 2015 will continue to serve for such terms.

Until declassification is complete, any newly created directorship will continue to be apportioned among the classes to maintain the number of directors in each class as nearly as equal as possible. Any director elected to fill a newly created directorship or vacancy will hold office for a term that coincides with the remaining term of the class of directors into which the director was elected. In all cases, each director will hold office until his or her successor has been elected and qualified or until the director’s earlier death, resignation, disqualification or removal from office, and, effective as of our annual meeting in 2016, directors may be removed with or without cause.

Other Non-Substantive Changes

The proposed amended and restated certificate of incorporation also includes certain non-substantive amendments to conform references to gender and the use of defined terms.

If the amended and restated certificate of incorporation is adopted, the Board intends to make conforming amendments to provisions of our bylaws to make them consistent with the amended and restated certificate of incorporation.

The Board of Directors unanimously recommends that you vote FOR the adoption of the amended and restated certificate of incorporation to declassify the Board of Directors.

Advisory Vote to Approve Executive Compensation

(Item 3 on the Proxy Card)

As required by Section 14A of the Securities Exchange Act of 1934, we are asking you to approve an advisory resolution on the compensation of our named executive officers as described in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives you the opportunity to endorse or not endorse our 2012 executive compensation programs and policies for the named executive officers through the following resolution:

RESOLVED, that the shareholders approve, on an advisory basis, the compensation of the company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K in the company’s proxy statement for the 2013 annual meeting of shareholders, including the Compensation Discussion and Analysis, the compensation tables and related narrative discussion.

For additional detail concerning the compensation of our named executive officers, please refer to the Compensation Discussion and Analysis beginning on page 32.

Although your vote is not binding on the Board of Directors or the Human Capital Committee, the Human Capital Committee will review the voting results and seek to understand the factors that influenced the vote. As it did last year, the Human Capital Committee will consider constructive feedback obtained through this process in making future decisions about our executive compensation programs and policies.

We currently hold a say on pay vote every year. Therefore, shareholders will next have an opportunity to cast a say-on-pay vote in 2014.

The Board unanimously recommends that you vote FOR approval of named executive officer compensation, as provided in the resolution above.

Approval of the Annual Incentive Plan

(Item 4 on the Proxy Card)

We are asking shareholders to approve the company’s Annual Incentive Plan (the “Plan”), which provides our officers and employees with the opportunity to earn cash incentive awards based primarily on our performance each year. The Plan was adopted by the Human Capital Committee of the Board of Directors on February 20, 2013 and effective as of January 1, 2013 (subject to shareholder approval with respect to the Executive Officer Incentive Plan subpart of the Plan, as described below).

Why We Are Seeking Shareholder Approval

Section 162(m) of the Internal Revenue Code (“Section 162(m)”) generally disallows a tax deduction for annual compensation paid to certain executive officers in excess of $1 million, unless it satisfies the “performance-based compensation” exception under Section 162(m). Qualified performance-based

##### Table of Contents

Items to Be Voted On

compensation must be paid solely on account of the attainment of one or more pre-established, objective performance goals, the material terms of which have been approved by shareholders. Therefore, we are seeking approval of the Plan in order not to lose the ability to take deductions with respect to awards granted to certain executive officers pursuant to the Executive Officer Incentive Plan subpart of the Plan by reason of Section 162(m).

We previously maintained the Unum Group Management Incentive Compensation Plan of 2008, as amended (the “2008 MICP”), which provided for the grant of annual incentive awards to officers and employees. No further awards will be granted under the 2008 MICP if shareholder approval of the Plan is obtained. If shareholder approval is not obtained, the Human Capital Committee will determine whether to continue to grant awards under the 2008 MICP, grant awards that are not intended to qualify as performance-based compensation for purposes of Section 162(m) under the Plan and/or adopt a different annual incentive compensation plan that is not Section 162(m)-qualified.

Under Section 162(m), the material terms of the performance goals required to be disclosed to and approved by shareholders include the employees eligible to receive compensation, a description of the business criteria on which the performance goals are based, and the maximum amount of compensation that can be paid to an employee.

The principal features of the Plan are summarized below. This summary is qualified in its entirety by reference to the full text of the Plan, which is attached to this proxy statement as Appendix B.

Summary of the Plan

Purpose and Design. The purpose of the Plan is to motivate participants to perform in a way that will enable the company to reach or exceed its goals. The Plan is a cash-based annual incentive plan, consisting of two subparts: (1) the Executive Officer Incentive Plan, under which incentive awards to our CEO and other executive officers designated by the Human Capital Committee (which we refer to in this summary as the “Committee”) are based upon the achievement of objectively determinable corporate performance goals measured over a period of up to twelve months; and (2) the Employee Incentive Plan, under which incentive awards to employees or officers who are not participants in the Executive Officer Incentive Plan are based upon the achievement of corporate and/or individual performance goals measured over a period of up to twelve months.

Eligibility. Participation in the Plan is limited to employees of the company and its subsidiaries at job levels approved by the Committee, which, as of December 31, 2012, included six people in the Executive Officer Incentive Plan and approximately 8,830 people in the Employee Incentive Plan.

Executive Officer Incentive Plan. Awards under the Executive Officer Incentive Plan granted to our CEO and other executive officers designated by the Committee are intended to be eligible to be fully deductible by the company in accordance with the deduction limits of Section 162(m). Each participant in the Executive Officer Incentive Plan is eligible to receive an award not to exceed $8 million if the company attains a threshold criteria of statutory after-tax operating earnings at least equal to $250 million for the prior fiscal year ending on December 31, which is greater than the amount required to cover dividends to shareholders and interest on recourse debt of the company. The Committee may not increase the maximum amount payable to any participant or with respect to an incentive award under the Executive Officer Incentive Plan but retains the discretionary authority to reduce the amount based on certain factors to be established by the Committee (including, for example, corporate or business unit performance against budgeted financial goals, achievement of non-financial goals, economic and relative performance considerations and assessments of individual performance). So long as any adjustment would not, in the reasonable judgment of the Committee, prevent an award intended to qualify for the

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | 89

##### Table of Contents

Items to Be Voted On

“performance-based compensation” exception under Section 162(m) from so qualifying, the Committee may also adjust any performance goals during or after a plan year to mitigate the unbudgeted impact of unusual or non-recurring gains and losses, accounting changes, acquisitions, divestitures or “extraordinary items” within the meaning of generally accepted accounting principles that were not foreseen at the time the performance goals were established.

Employee Incentive Plan. The Committee may designate any officer or employee of the company or its subsidiaries (or any category of employees), except for any executive officer who participates in the Executive Officer Incentive Plan, to participate in the Employee Incentive Plan for a given year. Awards under the Employee Incentive Plan are based on an individual’s contribution to the business of the company, as determined by the Committee based on subjective as well as objective measures. Performance goals may be different for different participants and may, but need not, be the same as the performance goals under the Executive Officer Incentive Plan. The Committee may choose to increase or decrease an award under the Employee Incentive Plan, regardless of the attainment of a performance goal.

Plan Administration. The Plan will be administered by the Committee. The Committee, among other powers set forth in the Plan, has the authority and discretion to:

| — |  | Designate participants;

| — |  | Establish the performance goals and target awards, and determine whether or to what extent such goals were achieved, for each year;

| — |  | Determine the amount of actual awards for each year, or determine the methodology for determination and the aggregate amount of awards under the Employee Incentive Plan, subject to the terms of the Plan;

| — |  | Increase, reduce or eliminate any award payable under the Employee Incentive Plan, regardless of the achievement of performance goals;

| — |  | Reduce or eliminate (but not increase) any award payable under the Executive Officer Incentive Plan, regardless of the achievement of performance goals;

| — |  | Decide all other matters that must be determined in connection with an award;

| — |  | Amend, modify or terminate the Plan; and

| — |  | Adopt such modifications, procedures, and subplans as may be necessary or desirable to effectuate the incentive compensation objectives of the company (except that no modification, procedure or subplan may be adopted if it would cause awards granted under the Executive Officer Incentive Plan intended to qualify as “performance-based compensation” under Section 162(m) to fail to so qualify).

The Committee may expressly delegate to the CEO or the Chair of the Committee some or all of the Committee’s authority under the first four items in the preceding list with respect to the Employee Incentive Plan, pursuant to guidelines approved by the Committee.

Termination and Amendment. The Committee may alter, amend, suspend or terminate the Plan in whole or in part, but no amendment that requires shareholder approval in order for the Executive Officer Incentive Plan to continue to comply with the performance-based compensation exemption from Section 162(m) will be effective unless it is approved by the Committee and the requisite vote of the shareholders of the company.

Certain Federal Income Tax Effects

Under current United States federal income tax regulations, when a participant receives payment of a cash incentive award under either the Executive Officer Incentive Plan or the Employee Incentive Plan, the amount of cash will be ordinary income to the participant and will, subject to Section 162(m) (to the extent applicable) and other applicable law, be allowed as a deduction for federal income tax purposes to the company.

Although the Executive Officer Incentive Plan is designed so that awards quality for the performance-based exception under Section 162(m), the Human Capital Committee reserves the right to grant awards that do not qualify for this exception, and, in some cases, the exception may cease to be available for some or all awards that otherwise so qualify. Thus, it is possible that Section 162(m) may disallow compensation deductions that would otherwise be available to the company.

Benefits to Named Executives and Others

In February 2013, the Human Capital Committee established the performance goals and target awards under the Executive Officer Incentive Plan and Employee Incentive Plan under the Plan for performance during calendar year 2013. Actual awards will depend on whether and to what extent the applicable performance goals are met, which cannot be determined as of the date of filing of this proxy statement. The following table shows the awards that we believe would have been received under the Plan in 2012 had the Plan been in effect at that time, which are the same as the awards received in 2012 under the 2008 MICP.

Ratification of Appointment of Independent Registered Public Accounting Firm

(Item 5 on the Proxy Card)

The Audit Committee of the Board of Directors has appointed Ernst & Young LLP as our independent registered public accounting firm (“independent auditor”) for 2013. As a matter of good corporate governance, the Board is seeking shareholder ratification of the appointment even though it is not legally required. If the appointment is not ratified, the Audit Committee will consider the shareholders’ views in the future selection of the company’s independent auditor.

Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting. They will have the opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

Policy for Pre-Approval of Audit and Non-Audit Services

The Audit Committee has a policy requiring advance approval of all audit and permissible non-audit services performed by the independent auditor. Under this policy, the Audit Committee sets pre-approved limits for specifically defined audit and non-audit services. The Committee considers whether such services are consistent with SEC rules on auditor independence. Specific approval by the Committee is required if fees for any particular service or aggregate fees for services of a similar nature exceed the pre-approved limits. The Committee has delegated to its chair the authority to approve permitted services, and the chair must report any such decisions to the Committee at its next scheduled meeting.

Proxies

We are soliciting proxies on behalf of the Board of Directors in connection with the Annual Meeting. This means we are asking you to sign a proxy designating individuals (known as proxies) to vote on your behalf at the Annual Meeting and at any later meeting to which the Annual Meeting may be adjourned or postponed. By use of a proxy, you can vote whether or not you attend the Annual Meeting.

Because we are soliciting your proxy, we are required to send you either our proxy materials or a Notice of Internet Availability of proxy materials (described in the next section). Our proxy materials include this proxy statement and our annual report to shareholders, which contains audited consolidated financial statements for our fiscal year ended December 31, 2012. If you received a printed copy of our proxy materials by mail, you also received a proxy card or voting instruction form for the Annual Meeting.

Internet availability of proxy materials

We are furnishing proxy materials to our shareholders primarily over the Internet. In most cases, we are mailing only a brief Notice of Internet Availability of proxy materials, rather than a full set of printed materials. The Notice of Internet Availability contains instructions on how to access our proxy materials and vote online. It also includes instructions on how to request paper or email delivery of our proxy materials. If you previously chose to receive our proxy materials electronically, you will continue to receive access to these materials via email until you elect otherwise. Our proxy materials may also be viewed on our website at www.unum.com by clicking “Investors” and then “Proxy Materials.”

Attending the Annual Meeting in person

If you attend the Annual Meeting in person, you must present photo identification, such as a driver’s license, and an admission ticket or proof of ownership of our shares as of the close of business on March 25, 2013, the record date. If you are a shareholder of record, your Notice of Internet Availability or the top half of your proxy card is your admission ticket. If you are a beneficial owner, you will need proof of ownership to enter the meeting. Examples of proof of ownership include a recent brokerage statement or letter from the holder of record (your broker, bank or other nominee) confirming your beneficial ownership on the record date. For your safety and that of other shareholders, we reserve the right to inspect all personal items prior to admission. If you arrive at the Annual Meeting without proper documentation or refuse to comply with our security procedures, you may not be admitted.

You are a “shareholder of record” if your shares are registered directly in your name with our registrar and transfer agent, Computershare Trust Company, N.A.

You are a “beneficial owner” if your shares are held through a broker, bank or other nominee (i.e., held in street name). In this case, the broker, bank or nominee is the shareholder of record.

Voting items and Board recommendations; Vote required; Abstentions and broker non-votes

You may either vote for, against or abstain on each of the voting items to be acted on at the Annual Meeting. The table below summarizes, for each voting item, the voting recommendation of the Board of Directors, the vote threshold required for approval, and the effect of abstentions and broker non-votes (i.e., shares held in street name that cannot be voted on certain matters by the shareholder of record because the beneficial owner has not provided voting instructions).

About the Annual Meeting and Voting

Majority voting standard for election of directors

Our bylaws provide that, in an election of directors where the number of nominees does not exceed the number of directors to be elected (an “uncontested election”), each nominee must receive a majority of the votes cast with respect to that nominee to be elected as a director. If an incumbent director is not re-elected under this majority voting standard, the director must offer to tender his or her resignation to the Board of Directors. The Governance Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. If the director who tenders his or her resignation is a member of the Governance Committee, that director will not participate in the Governance Committee’s recommendation to the Board. The Board will act on the Governance Committee’s recommendation and publicly disclose its decision and rationale within 90 days from the date of the certification of the election results.

Voting your shares

If you are a shareholder of record, you may vote your shares using any of the following methods:

| — |  | In person – Attend the Annual Meeting and vote in person.

| — |  | Mail – Mark, date and sign the proxy card and mail it to Proxy Services, c/o Computershare Investors Services, P.O. Box 43126, Providence, Rhode Island 02940-5138, using the accompanying pre-addressed, stamped envelope, so that it is received no later than the close of business on May 22, 2013.

| — |  | Internet or telephone – Visit www.envisionreports.com/unm to vote over the Internet or call toll free 1-800-652-VOTE (8683) to vote using a touchtone telephone, in either case no later than 2:00 a.m. Eastern Time, May 23, 2013. You will need the control number found on the Notice of Internet Availability or the proxy card.

For shareholders of record, votes submitted by mail, over the Internet or by telephone will be voted at the Annual Meeting by the proxies named in the proxy card in the manner you indicate. If you sign and return a proxy card without marking specific voting instructions, the proxies will vote your shares FOR each director nominee and FOR each other voting item, as recommended by the Board of Directors.

If you are a beneficial owner, please refer to the Notice of Internet Availability or voting instruction form provided to you by your broker, bank or other nominee for details on how to provide voting instructions to such person. If your broker, bank or other nominee does not receive voting instructions from you, whether your shares can be voted by such person depends on the type of item being considered for vote. The only item of business at the Annual Meeting for which your broker, bank or other nominee has discretion to vote your shares without your voting instructions is the ratification of the appointment of our independent registered accounting firm (Item 5). Unless it receives your voting instructions, your broker, bank or other nominee will not have discretion to vote your shares (a “broker non-vote”) on any other item of business at the Annual Meeting (Items 1 to 4), including the election of directors. To ensure that your shares are voted on each of the important matters being voted on at the Annual Meeting, we encourage you to provide instructions to your broker, bank or nominee on how to vote your shares. As noted above, beneficial owners may vote in person at the Annual Meeting only if they bring a legal proxy obtained from their broker, bank or other nominee.

About the Annual Meeting and Voting

Changing your vote and revoking your proxy

If you are a shareholder of record and wish to change your vote after submitting a proxy, you may revoke that proxy by submitting a new proxy (either by mailing a new proxy card or by providing new voting instructions over the Internet or by telephone), by giving written notice of revocation to our Corporate Secretary, or by attending the Annual Meeting and voting in person.

If you are a beneficial owner, you may revoke a previously submitted proxy by submitting new voting instructions in the manner specified by your broker, bank or other nominee. If you obtain a legal proxy from your broker, bank or other nominee, you may also revoke a previously submitted proxy by voting in person at the Annual Meeting and submitting it with a signed ballot that will be provided to you there.

Quorum

A quorum is required to transact business at the Annual Meeting and is reached if shareholders of record of a majority of the shares entitled to vote at the meeting are present in person or represented by proxies. Abstentions, broker non-votes and signed but unmarked proxy cards will count for purposes of determining whether a quorum is present at the Annual Meeting.

Inspectors of election

Representatives of our transfer agent, Computershare Trust Company, N.A., will tabulate the votes and act as inspectors of the election.

Other business

We are not aware of any business to be conducted at the Annual Meeting, other than as described in this proxy statement. If you submit a proxy, the individuals named on the proxy card will use their own judgment to determine how to vote your shares on any business not described in this proxy statement that is properly brought before the Annual Meeting.

Voting results

We will report the final voting results of the Annual Meeting on a Form 8-K to be filed with the SEC within four business days after the Annual Meeting.

Cost of proxy solicitation

We pay the cost of soliciting proxies from our shareholders. Proxies are solicited by mail, and may also be solicited personally, electronically or by telephone by our directors, officers or employees, though none will receive additional compensation for doing this. We have retained Innisfree M&A Incorporated to assist in the solicitation of proxies for the Annual Meeting. We will pay Innisfree a fee of $20,000 and reasonable out-of-pocket expenses for its services. We also reimburse brokers, banks and other nominees for their expenses in sending proxy materials to their customers who are beneficial owners and obtaining their voting instructions.

Shareholder proposals and nominations for our 2014 annual meeting

If you intend to submit a proposal for inclusion in the proxy statement for our 2014 annual meeting pursuant to SEC Rule 14a-8, it must be received by the Corporate Secretary at our principal executive offices no later than December 12, 2013. Submitting a shareholder proposal does not guarantee that we will include it in our proxy statement if the proposal does not satisfy the requirements of SEC Rule 14a-8.

Our bylaws also establish advance notice procedures with respect to proposals and director nominations submitted by a shareholder for presentation directly at an annual meeting, rather than for inclusion in our proxy statement. To be properly before our 2014 annual meeting, a notice of the business matter or nomination the shareholder wishes to present at the meeting must be received by the Corporate Secretary at our principal executive offices no earlier than January 23, 2014 and no later than March 10, 2014. All such proposals and director nominations must satisfy the requirements set forth in our bylaws, a copy of which is available on our website at www.unum.com by clicking on “Investors” and then “Corporate Governance” and may also be obtained at no cost from the Office of the Corporate Secretary.

Communications with the Board of Directors

Shareholders and interested parties may communicate with our non-executive Chairman, William J. Ryan, or any other director by contacting the Office of the Corporate Secretary as described on the following page .

In accordance with a process approved by our Board of Directors, the Corporate Secretary reviews all correspondence received by the company and addressed to non-management directors. A log and copies of the correspondence are provided to the non-executive Chairman (or lead independent director), who determines whether further distribution is appropriate and to whom it should be sent. Any director may at any time review this log and request copies of correspondence. Concerns relating to accounting, internal controls or auditing matters are promptly brought to the attention of our internal auditors and handled in accordance with procedures established by the Audit Committee. Copies of correspondence relating to corporate governance matters are also provided to the chair of the Governance Committee.

The Board has requested that certain items unrelated to the duties and responsibilities of the Board be excluded from the process, including mass mailings, resumes and other forms of job inquiries, surveys, business solicitations or advertisements, and matters related to claims or employment.

Additional Information

Eliminating duplicative proxy materials

A single proxy statement and annual report to shareholders, along with individual proxy cards, or individual Notices of Internet Availability will be delivered in one envelope to multiple shareholders having the same last name and address and to shareholders with multiple accounts registered at our transfer agent with the same address, unless contrary instructions have been received from an affected shareholder. This is known as “householding” and it enables us to reduce the costs and environmental impact of the Annual Meeting. We will deliver promptly upon written or oral request a separate copy of the proxy statement, annual report to shareholders or Notice of Internet Availability to any shareholder residing at a shared address to which only one copy was delivered. If you are a shareholder of record and would like to receive separate copies of our proxy materials, whether for this year or future years, please contact Computershare Investor Services by calling toll-free 800-446-2617 or by writing to them at P.O. Box 43069, Providence, Rhode Island 02940-3069. The same phone number and address may be used to request delivery of a single copy of our proxy materials if you share an address with another shareholder and are receiving multiple copies. If you are a beneficial owner, you should contact your broker, bank or other nominee.

(3) The consummation of a merger, consolidation, statutory share exchange or similar form of corporate transaction involving the Company or any of its Subsidiaries that requires the approval of the Company’s stockholders, whether for such transaction or the issuance of securities in the transaction (a “Reorganization”), or sale or other disposition of all or substantially all of the Company’s assets to an entity that is not an affiliate of the Company (a “Sale”), unless immediately following such Reorganization or Sale: (A) more than 50% of the total voting power of (x) the corporation resulting from such Reorganization or the corporation which has acquired all or substantially all of the assets of the Company (in either case, the “Surviving Corporation”), or (y) if applicable, the ultimate parent corporation that directly or indirectly has beneficial ownership of 100% of the voting securities eligible to elect directors of the Surviving Corporation (the “Parent Corporation”), is represented by the Company Voting Securities that were outstanding immediately prior to such Reorganization or Sale (or, if applicable, is represented by shares into which such Company Voting Securities were converted pursuant to such Reorganization or Sale), and such voting power among the holders thereof is in substantially the same proportion as the voting power of such Company Voting Securities among the holders thereof immediately prior to the Reorganization or Sale, (B) no person (other than any employee benefit plan (or related trust) sponsored or maintained by the Surviving Corporation or the Parent Corporation) is or becomes the beneficial owner, directly or indirectly, of 20% (30% with respect to deferred compensation subject to Section 409A of the Code) or more of the total voting power of the outstanding voting securities eligible to elect directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation), and (C) at least a majority of the members of the board of directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) following the consummation of the Reorganization or Sale were Incumbent Directors at the time of the Board’s approval of the execution of the initial agreement providing for such Reorganization or Sale (any Reorganization or Sale which satisfies all of the criteria specified in (A), (B) and (C) above shall be deemed to be a “Non-Qualifying Transaction”); or

(4) The stockholders of the Company approve a plan of complete liquidation or dissolution of the Company.

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any person acquires beneficial ownership of more than 20% (30% with respect to deferred compensation subject to Section 409A of the Code) of the Company Voting Securities as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided, that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur.

Administration of the Plan

3.2. Actions and Interpretations by the Committee. For purposes of administering the Plan, the Committee may from time to time adopt rules, regulations, guidelines and procedures for carrying out the provisions and purposes of the Plan and make such other determinations, not inconsistent with the Plan, as the Committee may deem appropriate. The Committee’s interpretation of the Plan, any awards granted under the Plan, and all decisions and determinations by the Committee with respect to the Plan are and shall be final, binding, and conclusive on all parties. Each member of the Committee is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company, the Company’s independent certified public accountants, Company counsel or any executive compensation consultant or other professional retained by the Company or the Committee to assist in the administration of the Plan.

(h) make all other decisions and determinations that may be required under the Plan or as the Committee deems necessary or advisable to administer the Plan;

(i) amend, modify or terminate the Plan as provided herein; and

(j) adopt such modifications, procedures, and subplans as may be necessary or desirable (i) to effectuate the compensation incentive objectives of the Company or (ii) to comply with provisions of the laws of non-U.S. jurisdictions in which the Company or any affiliate may operate, in order to assure the viability of the benefits of awards granted to Participants located in such other jurisdictions and to meet the objectives of the Plan; provided, however, that any such modifications, procedures and subplans shall not apply with respect to participation in the Executive Officer Incentive Plan if they would cause Incentive Awards thereunder to fail to qualify as “performance-based” compensation as defined in Section 162(m) of the Code.

Nothing contained in the Plan shall prevent or be deemed to prevent the Committee or the Company, any Subsidiary or any of their respective affiliates from adopting other or additional compensation arrangements for, or paying or providing any other or additional amounts or benefits to, its employees.

ARTICLE 4

Eligibility and Participation; Change in Control

4.1. General. Participation in the Plan is limited to such officers or employees, or categories of employees, of the Company as may be designated by the Committee from time to time. Participation in one Plan Year does not guarantee participation in any subsequent Plan Year.

4.2. New Hires. If a person is hired on or before September 30 of a Plan Year and is selected for participation in the Plan for such Plan Year, then, unless the Committee provides otherwise, he or she will become a Participant in the Plan as of the date of hire and (without limiting the other provisions of this Article 4) payment, if any, in respect of the Incentive Award will be prorated in an amount equal to the product of (i) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan, and (ii) a fraction, the numerator of which is the number of days in the Plan Year on and after the date of hire and the denominator of which is the number of days in such Plan Year. If an employee’s

##### Table of Contents

Appendix B

date of hire occurs after September 30, such employee shall not be eligible to become a Participant for the Plan Year in which the employee’s date of hire occurs.

4.3. Promotions. Subject to the penultimate sentence of this Section 4.3 and without limiting the other provisions of this Article 4, if a Participant is promoted on or before November 30 of a Plan Year from one job level to a higher job level, such Participant will be eligible to receive payment in respect of his or her Incentive Award for the Plan Year in which the promotion occurs in an amount equal to the sum of (i) the product of (A) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan (based on the Participant’s job level immediately before the promotion) and (B) a fraction, the numerator of which is the number of days in the Plan Year before the date of promotion during which the employee is a Participant in this Plan and the denominator of which is the number of days in such Plan Year, and (ii) the product of (C) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan (based on the Participant’s job level immediately after the promotion) and (D) a fraction, the numerator of which is the number of days in the Plan Year on and after the date of promotion and the denominator of which is the number of days in such Plan Year; provided, that if a Participant is promoted multiple times on or before November 30 of a Plan Year, the calculation of his or her Incentive Award for the Plan Year will account for all job levels held during the Plan Year based on the number of days in the Plan Year during which each job level was held; provided further, however, that any promotion occurring after November 30 of a Plan Year will not be factored into the Incentive Award calculation for such Plan Year, such Incentive Award instead being calculated as if the promotion had not occurred. If a person is promoted on or before November 30 of a Plan Year and is selected by the Committee to participate in the Plan as a result of such promotion, then, unless the Committee provides otherwise, he or she will become a Participant in the Plan as of the date of the promotion and payment, if any, in respect of the Incentive Award will (without limiting the other provisions of this Article 4) equal the product of (1) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan (based on the Participant’s job level immediately after the date of promotion), and (2) a fraction, the numerator of which is the number of days in the Plan Year on and after the date of promotion and the denominator of which is the number of days in such Plan Year. If a person is promoted after November 30 and is not a Participant in this Plan prior to such promotion, such person shall not be eligible to become a Participant for the Plan Year in which such promotion occurs.

4.4. Demotions. If a Participant is demoted during the Plan Year, the Committee may, at any time before payment in respect of Incentive Awards granted for the Plan Year in which such demotion occurs generally is made to other Participants and without limiting the other provisions of this Article 4, determine whether and the extent to which the Participant’s eligibility to receive payment in respect of his or her Incentive Award terminates or survives. The Committee may (without limitation) determine that the payment, if any, in respect of the demoted Participant’s Incentive Award will (without limiting the other provisions of this Article 4) equal the product of (1) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan (based on the Participant’s job level immediately before the date of demotion), and (2) a fraction, the numerator of which is the number of days in the Plan Year before the date of demotion during which the employee is a Participant in this Plan and the denominator of which is the number of days in such Plan Year.

4.5. Death, Disability, Retirement, Position Elimination and Job Requalification. Subject to Section 4.7 below:

(a) In the event of death, Disability or Retirement of a Participant during the applicable Plan Year on or after the last business day of March during such Plan Year, the

Notice of Annual Meeting of Shareholders and 2013 Proxy Statement | B-7

##### Table of Contents

Appendix B

Participant or the Participant’s Beneficiary, as applicable, will receive a prorated payment in respect of the Participant’s Incentive Award (subject to the terms and conditions of Section 4.5(c)).

(b) In the event a Participant incurs a termination of employment by reason of the elimination of his or her position or a Job Requalification in each case during the applicable Plan Year on or after the last business day of June during such Plan Year, the Participant will receive a prorated payment in respect of the Participant’s Incentive Award (subject to the terms and conditions of Section 4.5(c)).

(c) For purposes of Sections 4.5(a) and (b), and without limiting the other provisions of this Article 4, the prorated payment, if any, received in respect of an Incentive Award equals the product of (1) the amount earned in respect of the Incentive Award according to the terms and conditions of this Plan, and (2) a fraction, the numerator of which is the number of days in the Plan Year preceding the date of death, Disability, Retirement or termination of employment by reason of the elimination of a Participant’s position or a Job Requalification and the denominator of which is the number of days in such Plan Year. In each case, the Participant will be entitled to all or a portion of the prorated payment, if any, calculated according to the immediately preceding sentence only after taking into account manager recommendations as to the applicable Participant’s individual performance. Such prorated payments will in all cases be calculated and paid after the end of the Plan Year at the time that Participants generally receive payments of Incentive Awards under this Plan. Amounts paid on behalf of a deceased Participant will be paid to the Participant’s Beneficiary. For the avoidance of doubt, in the event of the Participant’s termination of employment by reason of Disability or Retirement, or in the event of the Participant’s death, in each case before the last business day of March of a Plan Year, or in the case of a Participant’s termination of employment by reason of the elimination of his or her position or a Job Requalification in each case before the last business day of June of a Plan Year, the Participant will forfeit any right to an Incentive Award for that Plan Year.

4.6. Other Terminations of Employment. Except as provided in Section 4.7, in the event of a Participant’s termination of employment during a Plan Year (or after the end of a Plan Year and before the time the Committee has approved the level of payment in respect of Incentive Awards granted for such Plan Year) other than by reason of death, Disability, Retirement, the elimination of his or her position or a Job Requalification, the Participant will forfeit any right to an Incentive Award for that Plan Year. For terminations that occur after the time the Committee approves the level of payment in respect of Incentive Awards granted for a Plan Year, but before payment is made in respect of such Incentive Awards, payment will be made as though the termination of employment had not occurred. Solely for purposes of the Plan, the employment relationship shall be treated as continuing while the Participant is on military leave, sick leave, or other bona fide leave of absence if the period of such leave does not exceed six months, or if longer, so long as the individual retains a right to reemployment, or is otherwise protected, with the service recipient under an applicable statute or by contract. A termination of employment shall not occur in a circumstance in which a Participant transfers employment from the Company to one of its Subsidiaries, transfers employment from a Subsidiary to the Company, or transfers employment from one Subsidiary to another Subsidiary.

4.7. Change in Control. In the event of a Change in Control, the Committee shall determine the level of payment, if any, in respect of outstanding Incentive Awards that would have been attained if the Plan Year had ended as of the end of the month immediately preceding the month in which the

B-8 | Notice of Annual Meeting of Shareholders and 2013 Proxy Statement

##### Table of Contents

Appendix B

Change in Control occurs based on actual performance through the end of the month immediately preceding the month in which the Change in Control occurs (the “CIC Vested Awards”). Thereafter:

(a) Each Participant who is actively employed (within the meaning of this Article 4) at the end of the Plan Year in which the Change in Control occurs shall be entitled to payment in respect of his or her Incentive Award in an amount equal to the greater of his or her CIC Vested Award and the amount, if any, earned in respect of the Incentive Award based on actual performance for the entire Plan Year.

(b) If the Plan is terminated during a Plan Year in which a Change in Control occurs upon or after such Change in Control, each Participant who is actively employed (within the meaning of this Article 4) at the time of such Plan termination shall be entitled to payment in respect of his or her Incentive Award in an amount equal to the greater of his or her CIC Vested Award and the amount, if any, earned in respect of the Incentive Award based on actual performance through the date of termination of the Plan.

(c) If a Participant’s employment is terminated by the Company without Cause during a Plan Year in which a Change in Control occurs upon or after such Change in Control, such Participant shall be entitled to payment in respect of his or her Incentive Award in an amount equal to the greater of his or her CIC Vested Award and the amount, if any, earned in respect of the Incentive Award based on actual performance through the date of termination of employment.

ARTICLE 5

Executive Officer Incentive Plan

5.1. Eligibility. Only the CEO and such other executive officers of the Company, if any, as shall be designated by the Committee are eligible to participate in the Executive Officer Incentive Plan. The Executive Officer Incentive Plan is designed with the intent that Incentive Awards earned hereunder are eligible to be fully deductible by the Company in accordance with the deduction limits of Section 162(m) of the Code.

5.2. Incentive Awards. Subject to Section 5.3 below, each Participant in the Executive Officer Incentive Plan shall be eligible to receive an Incentive Award not to exceed $8 million in the event that the Company attains statutory after-tax operating earnings at least equal to $236 million for the prior fiscal year ending on December 31, which is the approximate amount required to cover dividends to stockholders and interest on recourse debt of the Company. Within ninety (90) days after the commencement of the Plan Year for which Incentive Awards are granted under the Executive Officer Incentive Plan, the Committee will confirm the performance goal applicable to such Incentive Awards.

5.3. Negative Discretion. The Committee may not increase the amount payable under the Plan or with respect to an Incentive Award pursuant to Section 5.2, but retains the discretionary authority to reduce the amount. The Committee may establish factors to consider in implementing its discretion, including, but not limited to, corporate or business unit performance against budgeted financial goals (e.g., operating income or revenue), achievement of non-financial goals, economic and relative performance considerations and assessments of individual performance.

Appendix B

5.4. Certification of Results and Payout. As soon as possible after the audited results for the Company are available for the applicable Plan Year, the Committee will certify the level of attainment, if any, of the performance goals applicable to Incentive Awards for such Plan Year and calculate the resulting levels of payment in respect of Incentive Awards under the Executive Officer Incentive Plan. The Committee shall adjust any performance goals during or after the Plan Year to mitigate the unbudgeted impact of unusual or non-recurring gains and losses, accounting changes, acquisitions, divestitures or “extraordinary items” within the meaning of generally accepted accounting principles and that were not foreseen at the time such performance goals were established; provided, that such adjustments would not, in the reasonable judgment of the Committee, prevent an award intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code from qualifying as “performance-based compensation” within the meaning of Section 162(m) of the Code. Incentive Awards earned by Participants under the Executive Officer Incentive Plan will be paid in cash within thirty (30) days after the level of attainment of the applicable performance criteria has been certified by the Committee pursuant to this Section 5.4 and the amount has been approved by the Committee, and in all cases (except as otherwise approved by the Committee) Incentive Awards shall be paid no later than March 15 of the year following the year in which the Incentive Award is earned.

ARTICLE 6

Employee Incentive Plan

6.1. Eligibility. The Committee may designate any officer or employee, or any category of employees, of the Company or its Subsidiaries as a Participant or Participants, as applicable, in the Employee Incentive Plan for any Plan Year; provided, that no person who is a Participant in the Executive Officer Incentive Plan for a Plan Year may be a Participant in the Employee Incentive Plan for that same Plan Year.

6.2. Incentive Awards. Each Participant in the Employee Incentive Plan shall be eligible to receive an Incentive Award in connection with a particular Plan Year based on an individual’s contribution to the business of the Company, as determined by the Committee, which contribution may be assessed on nonobjective as well as objective measures.

6.3. Establishment of Performance Goals. Within ninety (90) days after the commencement of the Plan Year for which Incentive Awards are granted under the Employee Incentive Plan (or such later date as the Committee shall determine), the Committee will set the performance goal(s) applicable to such Incentive Awards. Such performance goals may, but need not, be the same as the performance goals under the Executive Officer Incentive Plan and may be different for different Participants within the Employee Incentive Plan. For example, the Committee may choose to use corporate performance goals in conjunction with individual performance goals for certain Participants and may set different performance goals for different Participants or classes of Participants in the Employee Incentive Plan.

6.4. Establishment of Incentive Award Targets. Within ninety (90) days after the commencement of the Plan Year for which Incentive Awards are granted under the Employee Incentive Plan (or such later date as the Committee shall determine), the Committee will determine the levels of payment (e.g., based on threshold, target, and maximum levels of attainment of the applicable performance goal(s)) in respect of such Incentive Awards, which may be set as either percentages of base salary or a range of dollar amounts. Such levels may, but need not, be the same with respect to each Participant or from Plan Year to another Plan Year. The Committee may, to the extent applicable, establish the weightings applicable to each Participant’s Incentive Award attributable to the level of

B-10 | Notice of Annual Meeting of Shareholders and 2013 Proxy Statement

##### Table of Contents

Appendix B

attainment of the applicable performance goals. If established, such weightings shall be expressed as a percentage of the target-level payment in respect of the Incentive Award that can be earned based on the level of attainment of the applicable performance goal.

6.5. Determination of Awards and Payout. As soon as reasonably practicable after the completion of the applicable Plan Year, the Committee will certify the level of attainment, if any, of the performance goals applicable to Incentive Awards for such Plan Year and calculate the resulting levels of payment in respect of Incentive Awards under the Employee Incentive Plan. The Committee shall have the right, for any reason, to increase, reduce or eliminate any Incentive Award earned under the Employee Incentive Plan, notwithstanding the achievement of (or failure to achieve) a specified performance goal. Incentive Awards earned by Participants under the Employee Incentive Plan will be paid in cash within thirty (30) days after the level of attainment of the applicable performance criteria has been certified by the Committee pursuant to this Section 6.5 and the amount has been approved by the Committee, and in all cases (except as otherwise approved by the Committee) Incentive Awards shall be paid no later than March 15 of the year following the year in which the Incentive Award is earned.

ARTICLE 7

Amendment, Modification and Termination

7.1. Amendment, Modification and Termination. The Committee may at any time and from time to time alter, amend, suspend, or terminate the Plan in whole or in part; provided, however, that no amendment that requires stockholder approval in order for Incentive Awards granted under the Executive Officer Incentive Plan to continue to be eligible to qualify as performance-based compensation within the meaning of Section 162(m) of the Code shall be effective unless the same shall be approved by the Committee and the requisite vote of the Company’s stockholders.

ARTICLE 8

General Provisions

8.1. Payment Recipient. All amounts payable under the Plan shall be paid to the appropriate Participant; provided, however, that a Participant may, by written instruction during the Participant’s lifetime on a form prescribed by Executive Compensation, designate one or more primary Beneficiaries to receive the amount payable hereunder following the Participant’s death, and may designate the proportions in which such Beneficiaries are to receive such payments. A Participant may change such designations from time to time, and the last written designation filed with the Committee prior to the Participant’s death shall control. A Beneficiary designation shall not be considered effective unless made on a form prescribed by Executive Compensation and which is delivered to Executive Compensation. If any Participant shall fail to designate a Beneficiary or shall designate a Beneficiary who shall fail to survive the Participant, the Beneficiary shall be the Participant’s beneficiary designated or otherwise determined under the employer-sponsored group life insurance plan covering the Participant, as amended from time to time.

8.2. Non-Assignability. None of the rights under the Plan shall be subject to the claim of any creditor of any Participant or Beneficiary, or to any legal process by any creditor of such Participant or Beneficiary, and none of them shall have any right to alienate, commute, anticipate, pledge, assign or encumber any of the rights under the Plan except to the extent expressly provided herein to the contrary.

##### Table of Contents

Appendix B

8.3. No Right to Continued Employment. Participation in the Plan shall not give any employee any right to remain in the Company’s employ. The Plan is not to be construed as a contract of employment for any period and does not alter the at-will status of any Participant.

8.4. Participant’s Rights Unsecured; Waiver and Release. The benefits payable under the Plan shall be paid by the Company each year out of the Company’s general assets. To the extent a Participant acquires the right to receive a payment under the Plan, such right shall be no greater than that of an unsecured general creditor of the Company. In consideration of the granting of the award, Participants may be required to execute an agreement which, among other things, waives and releases all claims, whether known or unknown, that the Participant may have against the Company, its affiliates, directors, officers, agents or employees arising out of or related to the Participant’s employment, except for those claims against the benefit plans of the Company. The waiver shall include such terms and conditions as shall be determined by the Committee in its discretion; provided that any such waiver and release shall comply with applicable laws and regulations, and, provided, further, that the Committee may direct that no waiver and release shall be obtained.

8.5. Income Tax Withholding and Offset. The Company shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the Plan and will offset against the remainder any advances, loans, debts, sales deficits or similar amounts a Participant owes the Company or any Subsidiaries or for which the Company or any Subsidiaries may be responsible.

8.6. Governing Law. This Plan, and the rights and obligations of the parties thereunder, will be governed by and construed in accordance with the laws of the State of Delaware.

8.7. Titles and Headings. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

8.8. Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include the plural.

The foregoing is hereby acknowledged as being the Annual Incentive Plan, as adopted as of January 1, 2013, subject to the approval by the stockholders of the Company at the 2013 annual stockholders’ meeting.
