Nominees for Election

The Company is a leading global insurance broker and risk advisor. Through its subsidiaries, Willis develops and delivers professional insurance, reinsurance, risk management, financial and human resources consulting and actuarial services to corporations, public entities and institutions around the world. We have approximately 21,000 employees around the world (including approximately 3,400 at our associate companies) and a network of in excess of 400 offices in approximately 120 countries.

Directors are responsible for overseeing the Company’s business around the globe consistent with their fiduciary duties. This requires highly-skilled individuals with various qualities, attributes and professional experience. The Governance Committee believes that the slate of nominees as a whole reflects the collective knowledge, integrity, reputation, and leadership abilities, and, as discussed more below, the diversity of skills and experience with respect to accounting and financial services, government and regulation, marketing and operations and global markets that the governance of the Company requires.

Qualifications

When recommending a person for new or continued membership on the Board, the Governance Committee considers each nominee’s individual qualifications in light of the overall mix of attributes represented on the Board and the Company’s current and future needs. In its assessment of each nominee, the Governance Committee considers the person’s integrity, experience, reputation, independence and when the person is a current director of the Company, his or her performance as a director. The Governance Committee considers each director’s ability to devote the time and effort necessary to fulfill responsibilities to the Company and, for current directors, whether each director has attended at least 75% of the aggregate of the total number of meetings held by the Board and any committee on which he or she served. In 2012 each director satisfied this requirement. The Governance Committee believes service on other public or private boards (including international companies) also enhances a director’s knowledge and board experience. It considers the experience of a director on other boards and board committees in both this nomination decision and in recommending the membership slate for each of the Company Board’s Committees.

The Governance Committee believes that including directors having current and previous leadership positions is important to the Board’s ability to oversee management. Extensive knowledge of the Company’s business and the industry is an important quality for directors. Additionally, because of the Company’s global reach, international experience or knowledge of a key geographic area is also important. As the Company’s business also requires continuous compliance with regulatory requirements and agencies, it is imperative for some directors to have legal, governmental, political or diplomatic expertise. If a person has served or currently serves in the public arena (whether through political service, employment as a CEO of a public company or membership on a board of a public company), his or her integrity and reputation is also a matter of public record on which Company and its shareholders may rely. The Governance Committee also believes that the Company distinguishes itself from its competitors through marketing and, as a result, a strong marketing perspective should be represented. In light of its public and global nature (including conducting business in different countries and currencies), the Company also seeks international experience and a high level of financial literacy and experience on the Board and Audit Committee.

Diversity

The Company is committed to maintaining diversity on the Board as provided in the Company’s Corporate Governance Guidelines. The Board and the Governance Committee believe that diversity on the Board is important to ensuring a rounded perspective. Diversity is broadly interpreted by the Board to include viewpoints, background, experience, industry knowledge, and geography, as well as more traditional characteristics of diversity, such as race and gender. We believe that our commitment is demonstrated by the current structure of our Board and the varied backgrounds and skill sets of our current directors and nominees, which include three women, a person of Asian descent and a mix of American, British and Irish citizens.

Item 11 — Executive Compensation

Compensation Discussion and Analysis

The following is an overview and analysis of the Compensation Committee’s philosophy and objectives in designing compensation programs for the Group CEO, the Group CFO, and the Company’s three other most highly compensated executive officers, collectively our “named executive officers.” For the fiscal year ended December 31, 2012, our named executive officers were:

• Joseph Plumeri (2012 CEO);

• Michael Neborak (Group CFO);

• Stephen Hearn (CEO and Chairman, Willis Global);

• Timothy Wright (CEO, Willis International); and

• Victor Krauze (CEO and Chairman, Willis North America).

Mr. Plumeri resigned as CEO on January 6, 2013 but remained as Chairman of the Board. He will retire as Chairman on July 7, 2013. Mr. Dominic Casserley became the current CEO of the Company, effective January 7, 2013. Mr. Hearn was appointed Deputy CEO, effective January 1, 2013.

1.0 Executive Summary of our Named Executive Officer 2012 Compensation

1.1. Background

The Compensation Committee establishes, implements, and monitors the Company’s compensation programs, philosophy, and objectives. The Committee has two primary objectives: (1) to attract and retain highly qualified executives in the competitive marketplace in which the Company operates; and (2) to create appropriate incentives for our executives to improve their individual performance. To achieve these objectives, the Compensation Committee evaluates and sets the total compensation for each of our named executive officers – base salary, annual incentive compensation, and long-term incentive compensation – considering the scope of the named executive officer’s role, level of expertise, individual performance, Company performance, and compensation paid to similarly-situated executives in our peer group companies. To assist the Compensation Committee in all aspects of the named executive officer and the Company’s compensation program, the Compensation Committee has retained Towers Watson as its independent compensation consultant.

The Compensation Committee spent significant time in 2012 reviewing, evaluating, and re-designing our named executive officer compensation program, partly in response to the “say-on-pay” vote at our 2012 Annual General Meeting. While a majority of shareholders approved our 2012 compensation program, the percentage approval was down considerably from 2011 (54% compared to 94%). Although this vote was non-binding, the Board and Compensation Committee wanted to understand why the approval rate was low, especially because our named executive officer compensation program remained essentially unchanged from 2011 to 2012.

Accordingly, at the Board’s and Compensation Committee’s direction, management reached out to the Company’s shareholders to understand their concerns. We learned that there was no single area of shareholder concern. Rather, our shareholders expressed a variety of concerns, not all of which related to compensation and included disappointment in the Company’s financial performance, concern about the level of CEO compensation relative to that performance (structured pursuant to his 2010 employment contract), use of guaranteed bonuses, the use of the same financial metrics for short-term and long-term incentive awards, use of non-traditional share ownership guidelines, and the lack of prohibitions against directors and executive officers entering into margin accounts and pledging shares.

14

The Committee and Board considered the results of the vote, the various viewpoints expressed by our shareholders and market factors, and adopted several changes to Company policies and our named executive officer compensation program, including:

• Revising the Company’s financial metrics for its 2013 annual incentive compensation awards and performance-based long-term incentive awards to emphasize both short-term and long-term financial performance. The annual and long-term incentive awards will have different metrics, all of which will be key drivers to increase cash flow and, therefore, important constituents of shareholder value enhancement.

• Confirming our philosophy that incentive pay should be performance driven and not guaranteed. Accordingly, unless there are compelling circumstances (i.e., on a limited basis, in connection with new hires), the Compensation Committee will not approve guaranteed incentive awards.

• Lowering our new CEO’s total target pay package by 26% compared to Mr. Plumeri and lowering his amount of fixed pay by almost 45%.

1.2 The Company’s 2012 Financial Performance and Named Executive Officer Compensation

2012 was characterized by an ongoing challenging macroeconomic environment, especially in two of our key geographic regions, Western Europe and North America. Reported EPS was ($2.58) and Adjusted EPS was $2.58 ($2.52 excluding the impact of foreign exchange) and our reported Operating Margin was (6.0%) and Adjusted Operating Margin was 21.6% (20.9% excluding the impact of foreign exchange). This compares to 2011 reported EPS of $1.15 and Adjusted EPS of $2.74 and reported Operating Margin of 16.4% and Adjusted Operating Margin of 22.5%. We refer to organic growth in commissions and fees, Adjusted EPS and Adjusted Operating Margin, which are Non-GAAP financial measures. A reconciliation of our GAAP to Non-GAAP financial information can be found in Exhibit A.

In a difficult environment, however, the Company also delivered the following:

• 1.3% reported commissions and fees growth and 3.1% organic commissions and fees growth;

• Significant improvement in the Company’s financial performance in the fourth quarter, with 7.5% organic commissions and fees growth (representing the best organic growth result in over six years) and improved Adjusted Operating Margin by 40 basis points; and

• Substantive progress on key growth initiatives (pipelines development and management, producer retention, and recruitment) and operational initiatives (Financial Transformation Project, global brokerage systems, global placement system).

While these results showed positive momentum moving into 2013, they did not meet established incentive targets, and, accordingly, the payout of our named executive officers’ 2012 annual incentive compensation awards was below target.

Mr. Plumeri’s annual incentive compensation award was calculated under the terms of his 2010 employment agreement, and was based on the Company’s performance measured by growth in Adjusted EPS (for 50% of the award) and Adjusted Operating Margin (for the remaining 50%). The Committee set “threshold,” “target” and “stretch” payout goals of 250%, 375% and 500%, respectively, of his base salary. After the 2012 budget had been approved, however, because of slow EPS growth compared to 2011, Mr. Plumeri proposed and the Compensation Committee agreed, to reduce his target payout from 375% to 250%. Based on the Company’s performance in 2012, Mr. Plumeri was awarded an annual incentive compensation award of $905,963, representing 24% of his original target payout and 36% of his revised target payout.

15

The annual incentive compensation awards for our four other named executive officers were based on a combination of the Company’s performance (60%) and individual and business unit performance (40%)¹. Based on that formula, the annual incentive compensation awards to our named executive officers were as follows:

• Michael Neborak was awarded $528,000, representing 88% of his target payout.

• Stephen Hearn was awarded £815,000 (or $1,291,775), representing 93% of his target payout.

• Timothy Wright was awarded £775,000 (or $1,228,375), representing 89% of his target payout.

• Victor Krauze was awarded $910,000. While he does not have a formal annual incentive compensation award target, this represents 74% of the target used for Messrs. Hearn and Wright.

Each named executive officer also received long-term incentive awards. Based on the Company’s financial performance, the performance-based portion of the awards were reduced to 88% of the grant value. As a result, the value of the 2012 long-term incentive awards for our named executive officers were as follows: Joseph Plumeri ($5,280,000); Michael Neborak ($940,000); Stephen Hearn £1,304,732 (or $2,068,000); Timothy Wright £889,590 (or $1,410,000); and Victor Krauze ($1,128,000). Stephen Hearn also received 6,500 restricted stock units in connection with his promotion to Chairman and CEO of Willis Global.

2.0 The Company’s Named Executive Officer Compensation Program

The Compensation Committee is responsible for establishing, implementing and monitoring the Company’s compensation programs, philosophy and objectives. The Company has two primary objectives in designing compensation programs for our named executive officers: (1) to attract and retain highly qualified and talented executives and professionals in the highly competitive marketplace in which the Company operates (which includes large financial services companies); and (2) to create appropriate incentives for our executives to improve their individual performance with the objective of improving the Company’s long-term performance, thereby creating value and wealth for our shareholders. Against those objectives, we consider each named executive officer’s total compensation in the context of compensation paid to similarly-situated executives in our peer group companies, the scope of the role, the individual’s level of expertise and other market factors, and the performance of the individual, his or her business unit and the Company.

2.1 Compensation Committee Consultant

The Compensation Committee has the independent authority to hire external consultants and, accordingly, has retained Towers Watson since April 2011 to provide advice to the Compensation Committee on all matters related to the senior executives’ compensation and compensation programs. The Compensation Committee has the independent authority to terminate Towers Watson’s services at its discretion. Representatives from Towers Watson attended all of the Compensation Committee’s regularly scheduled meetings in 2012.

Towers Watson reports directly to the Compensation Committee and provides data on U.S. and U.K. executive compensation trends in the sectors in which the Company competes for senior executive talent as well as the broader market. In 2012 and 2013, Towers Watson advised the Compensation Committee on the redesign of the named executive officer compensation program and, in particular, the compensation package of Mr. Casserley, the Company’s new CEO, and certain changes to the compensation packages for the Company’s other executive officers. Towers Watson also assists with selecting appropriate peer companies and assessing non-employee director compensation. The fees paid to Towers Watson in 2012 for these services totaled $167,866.

The Compensation Committee uses the data and analysis provided by Towers Watson to better ensure that the Company’s compensation practices are consistent with the Company’s compensation philosophy and objectives for both the amount and composition of executive compensation, including that of the CEO. Based on the data and analysis provided by Towers Watson as well as information from management and outside counsel, the

¹  The Company performance portion (60%) was calculated measuring Adjusted EPS against a target of $2.74 (50%) and Adjusted Operating Margin against a target of 21.8% (50%).

16

Compensation Committee applies business judgment in recommending compensation awards, taking into account the dynamic nature of the insurance sector internationally and the adaptability and response required by the Company’s leadership to manage significant changes that arise during the course of a year.

Before its appointment as the consultant to the Compensation Committee in 2011, Towers Watson had been providing investment advisory services for the Company’s UK pension plan and was engaged directly by the fiduciary trustees of the plan. These trustees operate independently of the Company’s management. In addition, Towers Watson also provides human resource consulting services to certain of the Company’s subsidiaries (the majority of which are international subsidiaries where Towers Watson was hired by local management). The additional services provided to the Company’s significant subsidiaries totaled $957,181 for 2012, of which $854,462 related to the services provided for UK pension plan and $102,719 related to the human resource consulting services. The decision to engage Towers Watson for the human resource consulting services before 2011 was originally approved by management and since that time the Compensation Committee has reviewed and approved such services. None of the Towers Watson representatives that advise the Compensation Committee provide any other services to the Company’s subsidiaries. The Compensation Committee determined that those services, based on the independence factors specified in the NYSE listing rules, produced no conflicts of interest.

2.2 Analysis of Alignment of Pay and Performance

In advance of the impending requirement under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Compensation Committee directed Towers Watson to analyze the alignment of total executive officers’ pay in relation to the Company’s performance as compared to the peer companies’ performance over a three-year performance measurement period (2009 – 2011). We evaluated our named executive officers’ performance over this period using the following key metrics: total shareholder return, Adjusted EPS growth and Adjusted Operating Margin. This performance was then compared to “realizable/earned pay,” which is defined as the actual value of compensation earned for the three-year measurement period and includes base pay, annual incentive compensation paid, “in the money” value of stock option grants, market value of time-vested RSUs and market/cash value of performance based awards. The analysis indicated in aggregate a strong alignment between our executive officers’ realizable/earned pay (62^nd percentile of our peer group) and the Company’s composite performance over the three-year measurement (75^th percentile of our peer group) period.

2.3 Peer Group and Market Data

As providers of insurance brokerage and risk consultancy services, we have no direct competitors of comparable financial size in our marketplace. However, we compete for talent with brokers of all sizes, with insurance carriers, and with companies in other financial services sectors. Accordingly, to assist the Compensation Committee in judging the reasonableness of its compensation recommendations, we typically use data related to a group of peer companies in the insurance sector, some of whom do not directly operate as insurance brokers.

The Compensation Committee reviews its peer group on an annual basis to ensure that it remains reasonable and justifiable. It seeks to avoid changes unless there is some significant rationale. The 2012 peer group, which has remained unchanged from 2010, was approved by the Compensation Committee following a review by Towers Watson and subsequent discussions between the Compensation Committee, Towers Watson and management. The peer group is a combination of large and small insurance brokers and insurance carriers and consists of:

Insurance Brokers	Insurance Carriers
AON plc	Ace Limited
Arthur J. Gallagher & Co.	Arch Capital Group Limited
Brown & Brown Inc.	Axis Capital Holdings Limited
Jardine Lloyd Thompson Group plc	The Chubb Corporation
Marsh & McLennan Companies, Inc.	XL Group plc

17

Our executive officers are based in both the United States and the United Kingdom. The country of each executive officer’s primary location is taken into account when reviewing and determining his or her annual base salary and, particularly, benefits.

In order to attract and retain exceptional senior executives, the Compensation Committee generally sets the executive officer’s base salary at the median but evaluates the executive officer’s total compensation (defined as base salary, annual incentive compensation and long-term incentive compensation) in the context of compensation paid to similarly-situated executives in our peer group companies, considering the scope of the role, the individual’s level of expertise and other market factors as well as both the performance of the individual and the Company.

The Compensation Committee reviews each element of compensation separately, as well as the total compensation of named executive officers. Compensation differences among the named executive officers reflect their different roles, their contributions, and the different market pay relating to those roles.

2.4 Redesign of Our Named Executive Officer Compensation for 2013 in Response to Advisory Vote

At our 2012 Annual General Meeting of Shareholders, a majority of votes (72,159,795 votes or approximately 54%) were cast in favor of the compensation of the Company’s named executive officers. Although this vote was non-binding, the Board and the Compensation Committee sought to understand why the approval rate was low, especially because our executive pay program had remained substantially the same as the program that received 94% support the previous year. Accordingly, at the Board and Compensation Committee’s request and under their guidance, management began an outreach program to the Company’s shareholders to gather feedback and enable the Board and the Compensation Committee to better understand shareholder concerns.

We solicited feedback through a survey and direct outreach to shareholders representing approximately 73% of the Company’s shares. We then engaged in substantial discussions with investors representing over 40% of our outstanding shares. During these discussions, we learned that there was no single area of shareholder concern. Rather, our shareholders expressed a variety of concerns, not all of which related to compensation and included disappointment in the Company’s financial performance, concern about the level of CEO compensation relative to that performance (structured pursuant to his 2010 employment contract), use of guaranteed bonuses, the use of the same financial metrics for short-term and long-term incentive awards, use of non-traditional share ownership guidelines, and the lack of prohibitions against directors and executive officers entering into margin accounts and pledging shares.

The Board and Compensation Committee considered the vote results and the viewpoints expressed by shareholders through the Company’s outreach efforts and, as a result, with input from their outside advisors, adopted several changes to Company policies and to the Company’s executive compensation program. It is important to note, however, that most of these changes did not take effect until 2013 and therefore will not be reflected until our 2014 Proxy Statement. The Board and Compensation Committee, with assistance from management, responded to the outreach program by:

• Seeking advice from its independent compensation consultant, Towers Watson, regarding the design of its new CEO compensation package, including the level of pay relative to the market, the mix of fixed to variable pay components and the relationship of the CEO’s pay level compared to the other named executive officers’ compensation.

• Revising Company financial metrics for its annual incentive compensation awards and performance-based long-term incentive awards to differentiate between and to emphasize both short-term and long-term financial performance.

18

• For annual incentive compensation awards for 2013, the Board and the Compensation Committee replaced previously used metrics, Adjusted EPS and Adjusted Operating Margin, with organic commissions and fees growth and Adjusted EBITDA. The Board selected those metrics because they believe they are key drivers of increasing cash flow and, therefore, important constituents of shareholder value enhancement. Additionally, Adjusted EBITDA (which excludes the impact of non-cash expenses, depreciation and amortization) is an appropriate short-term metric because it measures cash-based operating income and ensures that appropriate investment in the Company is encouraged.

• For the long-term incentive compensation awards for 2013, the Board and the Compensation Committee eliminated the one-year performance period targets and adopted three-year performance period targets to encourage sustained financial performance. They also replaced previously used metrics, Adjusted EPS and Adjusted Operating Margin, with organic commissions and fees growth and Adjusted EBIT (modified by a cost of capital charge for acquisitions or a cost of capital credit for dispositions made during the performance period). Adjusted EBIT (modified as described above) is an appropriate long-term metric because it provides management accountability for investment decisions (mergers and acquisitions and capital expenditures) over time.

• Adopting a strict policy prohibiting directors and executive officers from entering into margin accounts or pledging shares.

• Confirming our philosophy that incentive pay should be performance driven and not guaranteed. Accordingly, unless there are material and compelling circumstances (i.e., on a limited basis, in connection with new hires), the Compensation Committee will not approve guaranteed incentive awards. As discussed further below, our new Chief Executive Officer’s compensation does not include any guaranteed annual incentive compensation awards.

• Revising our executive officer share ownership guidelines to require each executive officer to own shares equivalent in value to a multiple of his or her base salary, as set forth below:

Position	Multiple
Group CEO		6.0 x base salary
Executive Officers Leading Major Business Units and Group CFO		3.0 x base salary
Other Executive Officers		2.0 x base salary

Executives are required to retain at least 50% of shares received under equity award programs until the ownership guidelines are met.

• Finally, as discussed below, we changed the design of our new CEO’s compensation.

In January 2013, the Board appointed Dominic Casserley as the Company’s new CEO. The Company recruited Mr. Casserley from McKinsey & Company, where he led McKinsey’s Greater China Practice and its UK and Ireland Practice and served as a senior partner and member of the firm’s global board. Consistent with the Compensation Committee’s and Board’s compensation philosophy for 2013 and beyond, we structured the CEO compensation as follows:

• Lowered the CEO’s total target pay package by over 25% compared to Mr. Plumeri resulting in less disparity between the compensation of the CEO and other named executive officers.

19

• Lowered the CEO’s amount of fixed pay by almost 45%, increased the proportion of long-term incentive compensation relative to annual incentive compensation, as illustrated below, and added a cap on his annual incentive compensation awards.

• Provided the CEO, as a transition payment, with a one-time sign-on cash award of $1,500,000, which will not be paid until the start of his second year of service. We believed this payment was reasonable and consistent with market practice given that our CEO was moving from McKinsey & Company’s all-cash based compensation system to a system that combines cash and equity.

• Provided that the CEO’s 2013 annual incentive compensation awards, if any, will be paid partially in equity.

• Revised the CEO’s 2013 annual incentive compensation award to be based 80% on the Company’s financial metrics and 20% on strategic goals, with no guaranteed payment.

• Continued the practice of providing a double trigger for accelerating vesting of the CEO’s equity upon a change of control.

2.5 Summary Chart of the Components of Our Named Executive Officers Compensation

The chart below sets forth the main components, objectives, key features and details of our named executive officer compensation program. It also highlights certain features adopted by the Compensation Committee in response to the Company’s shareholder outreach program that will be included within our 2013 named executive officer compensation and reflected in the 2014 proxy. As discussed in more detail in Section 3.0, the three components of our named executive officers’ compensation are: base salary, annual incentive compensation, and long-term incentive compensation.

Component	Objective	Key Features/Detail	Forward-Looking Changes
BASE SALARY (Fixed)	•        Provide secure base of cash compensation •        Attract and retain highly talented executives	•        Positioned at/around median level in our peer group companies •        Salary adjustments made only to reflect changes in responsibilities or when competitive market conditions warrant	•        Lowered the CEO’s amount of fixed pay by almost 45%.
ANNUAL INCENTIVE COMPENSATION (Variable)	•        Incent and reward executive officer contribution in generating: •        strong financial performance at Company •        strong financial/strategic performance at their business/functional unit •        Retain strong performers •        Provide annual performance-driven wealth creation	•        Awards for the CEO were based 100% and awards for the other named executive officers were based 60% on the Company’s performance against established targets for certain financial metrics(1)(2) that include: •        Adjusted Operating Margin •        Adjusted EPS •        Paid entirely in the form of cash(3) •        Payout determined using annual incentive sliding scale that incorporated symmetrical relationship between performance and payouts •        Company financial metrics had a higher performance threshold for the CEO than the other named executive officers and the pool established for other employees (resulting in a zero payout to Mr. Plumeri with respect to the Adjusted EPS measure) •        The Company utilized a high ratio of variable pay to fixed pay to tie compensation to performance. For example, because performance metrics were not achieved, Mr. Plumeri’s annual incentive award was reduced to 24% of his original target payout and 36% of his reduced target payout.	•        Annual incentive compensation awards for 2013 performance period will be determined using new revenue and profit metrics(4): •        Organic Commissions and Fees Growth •        Adjusted EBITDA •        Compensation Committee confirmed its philosophy that incentive pay should be performance driven and not guaranteed(5) •        Company financial metrics have a higher performance threshold for the CEO and other named executive officers than the pool established for other employees •        A cap has been added to the CEO’s annual incentive compensation awards •        For the CEO, lowered the proportion of target annual incentive compensation relative to long-term incentive compensation

21

LONG-TERM INCENTIVE COMPENSATION   (Variable) •        Align executive officers’ interests with those of our shareholders   •        Incent long-term decision making   •        Reward exceptional performance by executive officers   •        Retain strong performers •        Grants made in the form of   •        performance-based RSUs   •        time-based options   •        time-based RSUs   •        Earned performance-based RSUs were based on the Company’s performance against established targets for certain financial
metrics⁽²⁾⁽³⁾ that include:   •        Adjusted Operating Margin   •        Adjusted EPS   •        Earned performance-based RSUs were determined using long-term incentive sliding scale that incorporates symmetrical relationship between performance and payouts   •        Dividends were not payable on any performance-based RSUs •        Earned performance portion of 2013 long-term incentive compensation will be determined using new revenue and profit metrics that are different from annual incentive compensation metrics⁽⁴⁾:   •        Organic Commissions and Fees Growth   •        Adjusted EBIT (with Cost of Capital Modifier)   •        2013 Long-Term Incentive Program will include three-year performance period to better reflect pay for long-term performance   •        For CEO, increased the proportion of long-term incentive compensation relative to annual incentive compensation

(1) These financial metrics represented how the Company manages its profitability (Adjusted Operating Margin) and enhances growth in shareholder value (Adjusted EPS).

(2) These financial metrics were the same for all employees in the Company and its subsidiaries, who received annual incentive compensation awards or performance-based equity.

(3) From time to time, the Company may pay a portion of annual incentive compensation awards in the form of RSUs, provided there is sufficient available share capacity.

(4) The Board and Compensation Committee believe these metrics are key drivers of cash flow and shareholder value creation.

(5) Accordingly, unless there are material and compelling circumstances (i.e., on a limited basis, in connection with new hires), the Compensation Committee will not approve guaranteed incentive awards.

3.0 Named Executive Officer Compensation for 2012

3.1 The Company’s 2012 Financial Performance

2012 was characterized by an ongoing challenging macroeconomic environment, especially in two of our key geographic regions, Western Europe and North America. Reported EPS was ($2.58) and Adjusted EPS was $2.58 ($2.52 excluding the impact of foreign exchange) and our reported Operating Margin was (6.0%) and Adjusted Operating Margin was 21.6% (20.9% excluding the impact of foreign exchange). This compares to 2011 reported EPS of $1.15 and Adjusted EPS of $2.74 and reported Operating Margin of 16.4% and Adjusted Operating Margin of 22.5%.

As discussed below, these results were below the incentive targets established by our Compensation Committee and, accordingly, the Committee and the Board reduced our named executive officers’ incentive awards. However, the Company also delivered the following in 2012:

• 1.3% reported commissions and fees growth and 3.1% organic commissions and fees growth:

• 6.1% organic commissions and fees growth in our Global segment;

• 4.9% organic commissions and fees growth in our International segment; and

• (0.6)% decline in organic commissions and fees in our North America segment, representing a significant improvement over the prior year.

• Significant improvement in the Company’s financial performance in the fourth quarter, with 7.0% reported commissions and fees growth, 7.5% organic commissions and fees growth (representing the best quarterly organic growth result in over six years) and improvement in Adjusted Operating Margin by 40 basis points.

• 2012 cash flow from operating activities of $525 million, up $86 million, or 20%, from the prior year.

• $285 million returned to shareholders through share repurchases and dividends.

• Substantive progress on key growth initiatives (pipeline development and management, producer retention and recruitment) and operational initiatives (Financial Transformation Project, global brokerage systems, global placement system).

3.2 Named Executive Officers’ Annual Compensation

The key components of our named executive officers’ annual compensation are:

• Base salary;

• Annual incentive compensation (payable in cash and/or equity awards); and

• Long-term incentive compensation.

Base Salary — Base salary is intended to provide a fixed level of remuneration to fairly compensate and retain executives for their time and effort based on the individual’s role, experience and skill. The Compensation Committee strives to set base salary at a competitive level in the relevant markets in which our executive officers operate. Base salaries are reviewed by the Compensation Committee for all the Company’s executive officers relative to our peer group and, from time to time, against other U.S. or U.K. survey data, as applicable. The base salary levels are generally positioned around the median of our peer group companies. In line with our compensation philosophy, exceptional performance by our executive officers is generally rewarded through annual and/or long-term incentive compensation and not through base salaries. Before he resigned as CEO effective January 6, 2013, Mr. Plumeri’s base salary had not changed since he joined Willis in October 2000. This reflects the Company’s and Mr. Plumeri’s shared view that his pay was best aligned with shareholder interests if most of his annual compensation was at risk and tied to the Company’s performance.

23

Adjustments to base salaries are made by the Compensation Committee to reflect changes in responsibilities or when competitive market conditions warrant. The following reflects the changes to the base salaries of our named executive officers during the past year:

• Based on the results of a market review, effective April 2012, Mr. Neborak received an increase to his annual base salary to $600,000 from $500,000.

• As a result of the increase in responsibilities related to his promotion to Chairman and CEO of Willis Global, Mr. Hearn received an increase in his annual base salary to £500,000 ($792,500) from £400,000 ($634,000), effective January 1, 2012. As a result of the increase in responsibilities related to his promotion to Deputy CEO, Mr. Hearn received a further increase in his annual base salary to £530,000 ($840,050), effective January 1, 2013.

• As a result of increase of responsibilities related to his promotion to CEO of Willis International, Mr. Wright received an increase in his annual base salary to £500,000 (or $792,500) from £405,000 (or $641,925).

• Based on the increased scope of his role and increasingly competitive market conditions, effective April 2012, Mr. Krauze received an increase to his annual base salary $700,000 from $625,000.

Annual Incentive Compensation — Our annual incentive compensation plan is designed to incent and reward our named executive officers for their contribution in generating strong financial performance at the Company, strong financial or strategic performance at their business or functional unit, as well as to retain strong performers.

The Compensation Committee set Mr. Plumeri’s annual incentive compensation for 2012 in accordance with his 2010 employment agreement. Other than Mr. Plumeri, each named executive officer is eligible to receive an annual incentive compensation award under the Company’s Annual Incentive Plan (“AIP”). AIP awards are an integral component of the executive officer’s total compensation and are based on specific company financial results as well as individual executive officer strategic objectives. The AIP is intended to deliver exceptional pay for exceptional performance and provides a well-timed link between recent performance and individual compensation, which is especially pertinent with the de-emphasis on regular base-pay increases.

Annual incentive compensation, which may be paid in cash and/or equity, is granted under the Willis Group Senior Management Incentive Plan (the “SMIP”) to the extent named executive officers are “covered employees” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”). Generally, annual incentive compensation awards to the executive officers are approved and, for named executive officers who are “covered employees” under Section 162(m), are typically certified by the Compensation Committee in February, with payments made in March. Previously, if annual incentive compensation awards were paid in the form of a cash retention award, then the executive officer would be required to repay a proportionate amount of the award if he or she voluntarily left the Company’s employment before a specified date, which was generally three years. In December 2012, the Board changed its Company-wide remuneration policy and eliminated the repayment requirement from prior annual cash retention awards. Awards for 2012 were in the form of standard cash bonuses which do not include a repayment requirement. Current and prior annual incentive compensation awards continue to remain subject to the clawback provisions discussed in Section 4.0.

Annual Incentive Compensation Award for Joseph Plumeri (2012 CEO)

Pursuant to Mr. Plumeri’s 2010 employment agreement, Mr. Plumeri’s annual incentive compensation award was based 100% on the achievement by the Company of certain performance targets. Accordingly, pursuant to that 2010 agreement, each fiscal year the Compensation Committee established a threshold, target, and stretch financial performance goals (with maximum goals being no greater than 110% of the target goal). In February 2012, consistent with 2011 and based on the criteria in his employment agreement, the Compensation Committee approved annual incentive compensation performance goals of:

Threshold Payout	Target Payout	Stretch Payout
250% of his base salary if 95% of the performance targets were achieved.	375% of his base salary if 100% of the performance targets were achieved.	500% of his base salary if 105% of the performance targets were achieved.

24

Upon final approval of the 2012 budget, however, in consideration for the lack of growth in the Adjusted EPS target for 2012 relative to 2011, Mr. Plumeri proposed and the Compensation Committee agreed, to reduce his target payout to 250% (down from 375%) if 100% of the financial targets were achieved. This change is reflected in the revised payout column in the table below entitled “Summary of Annual Incentive Compensation Calculation For all Named Executive Officers.”

In 2012, the Company financial measures used for determining Mr. Plumeri’s annual incentive compensation award were Adjusted EPS (for 50% of the payment) and Adjusted Operating Margin (for 50% of the payment). These are measures that represent how the Company manages its profitability (through the use of the Adjusted Operated Margin) and enhances growth in shareholder value (as measured by the Adjusted EPS).

Applying the Company’s performance against Mr. Plumeri’s Adjusted EPS target produced the following opportunity:

Adjusted EPS Target	Payout          Opportunity         as a % of Base  Salary (Original)	Payout          Opportunity         as a % of Base Salary (Revised)
(Stretch) $2.88	250%	250%
(Target) $2.74	187.5%	125%
(Threshold) $2.60	125%	83.5%
<$2.60	0%	0%

As set forth in the Company’s Annual Report on Form 10-K for the year ended 2012, the Company reported Adjusted EPS of $2.58. The Compensation Committee, however, eliminated the positive impact of foreign exchange (deemed outside of management’s control) and thus reduced, for compensation purposes, 2012 Adjusted EPS to $2.52. Because the Company did not achieve the Adjusted EPS threshold of $2.60, this portion of Mr. Plumeri’s annual incentive compensation award was $0.

Applying the Company’s performance against Mr. Plumeri’s Adjusted Operating Margin target produced the following result:

Adjusted Operating Margin Target	Payout          Opportunity         as a % of Base Salary (Original)	Payout          Opportunity         as a % of Base Salary (Revised)
(Stretch) 22.9%	250%	250%
(Target) 21.8%	187.5%	125%
(Threshold) 20.7%	125%	83.5%
<20.7%	0%	0%

As set forth in the Company’s Annual Report on Form 10-K for the year ended 2012, the Company reported Adjusted Operating Margin of 21.6%. The Compensation Committee eliminated the positive impact of foreign exchange and this reduced, for compensation purposes, 2012 Adjusted Operating Margin to 20.9%. Because the Company exceeded the 20.7% threshold and met 96% of the 21.8% target, this portion of Mr. Plumeri’s annual incentive compensation award was 48% of his target payout opportunity or 72% of his revised total target payout opportunity or $905,963.

25

Accordingly, based on the formula discussed above, combining the results of both the Adjusted EPS and Adjusted Operating Margin formulas, the Compensation Committee approved an annual incentive compensation award to Mr. Plumeri of $905,963 (i.e., 24% of his total target payout opportunity of $3,750,000 or 36% of his revised total target payout opportunity of $2,500,000). Because Mr. Plumeri is no longer serving as the Company’s CEO and will retire as Chairman of the Board on July 7, 2013, the Compensation Committee elected to pay Mr. Plumeri’s 2012 annual incentive compensation award 100% in cash rather than partially in equity and partially in cash as in prior years.

Annual Incentive Compensation Awards for Michael Neborak, Stephen Hearn, Timothy Wright and Victor Krauze

The 2012 annual incentive compensation awards under the AIP for Messrs. Neborak, Hearn, Wright and Krauze were structured by the Compensation Committee as follows:

• 60% based on the following Company financial results:

• 30% based on how the Company performed against an Adjusted EPS target of $2.74 per share (the same target used for the payout pool for all Company employees in the AIP); and

• 30% based on how the Company performed against an Adjusted Operating Margin target of 21.8% (the same target used for the payout pool for all Company employees in the AIP); and

• 40% based on how the named executive officer performed against individual strategic objectives, which for Messrs. Hearn, Wright and Krauze was largely based on the financial performance of their business units.

The resulting percentage was applied against the officer’s annual incentive compensation target award, which is a percentage of the officer’s base salary. Under Mr. Hearn’s amendment to his employment agreement as a result of his promotion to Chairman and CEO of Willis Global in early 2012, he was entitled to receive a minimum AIP for the first year in his new role. Based on his performance as described below, Mr. Hearn’s actual AIP award exceeded this minimum. No executive officer has any guaranteed annual incentives for 2013.

Company Performance Portion of Annual Incentive Compensation (60% of AIP)

With respect to the EPS-based component of the award, the following scale applied:

Adjusted EPS Target	Payout as % of Base Salary
$2.88	110%
$2.74	100%
$2.60	90%
$2.47	80%
$2.33	70%
<$2.33	0%

As stated above, the Company reported 2012 Adjusted EPS of $2.58, but the Compensation Committee eliminated the positive impact of foreign exchange, reducing Adjusted EPS to $2.52. Based on the above sliding scale, because the Adjusted EPS result was between the $2.74 and $2.60, this portion of each named executive officer’s annual incentive award was funded at 84%.

26

With respect to the Adjusted Operating Margin component of the award, the following scale applied:

Adjusted Operating Margin Target	Payout Measurement
22.9%	110%
21.8%	100%
20.7%	90%
19.6%	80%
18.5%	70%
<18.5%	0%

As stated above, the Company reported 2012 Adjusted Operating Margin of 21.6%, but the Compensation Committee eliminated the positive impact of foreign exchange, reducing Adjusted Operating Margin to 20.9%. Based on the above sliding scale, this produced a payout percentage of 92% for this portion of each of the named executive officer’s annual incentive award.

Based on the application of the above two scales, the blended payout percentage for the Company’s performance against the Adjusted EPS and Adjusted Operating Margin targets was 88% of target. This comprised 60% of each of the named executive officer’s annual incentive compensation award.

Individual Strategic Objectives and Business Unit Financial Goals (40% of AIP)

The Compensation Committee then considered the individual strategic objectives and business unit financial goals based on operating income and organic commissions and fees growth for Messrs. Neborak, Hearn, Wright and Krauze which were established at the beginning of 2012. The Compensation Committee reviewed the executives’ performance against those objectives in the context of the overall Company financial and strategic performance. Key factors and resulting payout decisions are set forth below:

Michael Neborak

• Led efforts to contain group-wide expense growth.

• Made significant progress in Financial Transformation Project.

• Completed 3-year Financial Operating Model.

As a result of the achievement of these goals, the Compensation Committee funded this portion of his annual incentive compensation award at 88%.

Stephen Hearn

• Willis Global achieved $372 million operating income and 6.1% organic commissions and fees growth.

• Demonstrated leadership in development of a vision and strategy for the alignment of the Global business.

• Made significant progress in the deployment of an enterprise-wide placement initiative.

• Demonstrated leadership and support during the CEO transition.

As a result of the achievement of these goals, the Compensation Committee funded this portion of his annual incentive compensation award at 100%.

Timothy Wright

• Willis International achieved operating income of $183 million and 4.9% organic commissions and fees growth.

27

• Achieved notable year-over-year commissions and fees growth despite poor economies in major markets, with growing momentum in the second half of 2012.

• Supported the deployment of enterprise-wide placement initiative in all major countries.

As a result of the achievement of these goals, the Compensation Committee funded this portion of his annual incentive compensation award at 89%.

Victor Krauze

• Willis North America achieved $240 million of operating income. Despite a full-year decline in organic commissions and fees of (0.6)%, it achieved substantial shift in growth momentum culminating in 3.1% organic growth in the fourth quarter of 2012.

• Expanded emphasis on producer recruitment resulting in 3.2% net producer growth in 2012.

• Continued to successfully deploy Sales 2.0.

Despite these achievements, the Compensation Committee funded this portion of his annual incentive compensation award at 54%, reflecting the overall impact of Willis North America’s financial results on Company performance.

The following table sets forth the calculation for 2012 annual incentive compensation awards all named executive officers:

(1) Messrs. Hearn and Wright receive their salaries and bonuses in pounds sterling; the above figures have been converted into dollars at the average exchange rate for 2012 (£1:$1.585).

(2) Mr. Krauze did not have a formal bonus target. To calculate Mr. Krauze’s 2012 bonus the Compensation Committee utilized the same bonus target as Messrs. Hearn and Wright (175% of salary).

All annual incentive compensation awards were paid in cash. Further details of the 2012 annual incentive compensation awards made to our named executive officers are shown in the Bonus and Non-Equity Incentive Plan Columns of the “Summary Compensation” table.

Further details regarding the changes made to the 2013 annual incentive compensation program of our CEO and other named executive officers are reflected in Section 2.4, “The Redesign of Our Named Executive Officer Compensation for 2013 in Response to Advisory Vote” and Section 2.5 “Summary Chart of the Components of Our Named Executive Officers Compensation.”

Long-Term Incentive Compensation

Our long-term incentives are a significant element of our executive officers’ compensation and have typically been in the form of equity awards. For several years, we did not have a consistent long-term incentive program and. in 2010, in light of economic conditions, we did not make regular equity awards to our named executive officers except to satisfy pre-existing commitments or in connection with sign-on equity awards made to attract new competitive talent to the Company. In 2011, we implemented a Long-Term Incentive Program for senior leaders. In that year, we granted options and deferred cash as a portion of the long-term incentive plan as an alternative to the use of RSUs due to the lack of share availability under the Company’s equity plans at the time.

2012 Long-Term Incentive Program

In April 2012, the Compensation Committee adopted the 2012 Long-Term Incentive Program (the “2012 LTI Program”), which had both performance-based and time-based components to both reward performance and help ensure retention. Grants of options, performance-based RSUs and time-based RSUs were made in December 2012 and, for the performance-based equity, included performance targets established in the second quarter of 2012. All named executive officers, other than Mr. Plumeri, were eligible to participate and, as a result, Messrs. Neborak, Hearn, Wright and Krauze received awards under the 2012 LTI Program.

For the named executive officers, their individual 2012 awards were comprised of:

Options			Performance-Based RSUs	Time-Based RSUs
	25	%	50%	25%

The equity granted under the 2012 LTI Program was made under the recently adopted Willis Group Holdings Public Limited Company 2012 Equity Incentive Plan (the “2012 Plan”). The options, time-based RSUs and performance-based RSUs earned based on the performance of the 2012 targets discussed below, will vest 50% on the second and third anniversaries of the grant date (i.e., December 26, 2014 and December 26, 2015), subject to the continued employment of the participant during the vesting period. Dividends are not payable on any of the equity granted under the 2012 LTI Program.

Similar to the annual incentive compensation awards, the amount of performance-based RSUs granted under the 2012 LTI Program would be earned 50% based on the achievement of an Adjusted EPS target of $2.74 and 50% based on the achievement of an Adjusted Operating Margin target of 21.8%. However, if the targets were not achieved at 100%, the earned amount of the performance-based RSU award would be reduced in accordance with the following sliding scales:

Performance Against Applicable Adjusted EPS Target	% of Earned Performance Based-RSUs
$2.74	100%
$2.60	90%
$2.47	80%
<$2.47	0%

29

Performance Against Adjusted Operating Margin Target	% of  Earned Performance Based-RSUs
21.8%	100%
20.7%	90%
19.6%	80%
<19.6%	0%

The Compensation Committee applied the same analysis in determining financial performance against applicable targets that they used in determining the annual incentive compensation awards for the named executive officers. As a result, 88% of the performance-based RSUs granted under the 2012 LTI Program were earned by the respective named executive officer and they received long-term incentive awards equal in value to: Michael Neborak ($940,000); Stephen Hearn £1,304,732 (or $2,068,000); Timothy Wright £889,590 (or $1,410,000); and Victor Krauze ($1,128,000).

Grants to 2012 Named Executive Officers Outside of the 2012 Long-Term Incentive Program

In 2012, under the terms of his 2010 employment agreement, performance-based RSUs were granted to Mr. Plumeri. This was the last equity grant required under Mr. Plumeri’s employment agreement.

The RSUs were 100% performance related and similar to the performance-based RSUs granted under the 2012 LTI Program, 50% of the award would be earned if an Adjusted EPS target of $2.74 was met and 50% of the award would be earned if an Adjusted Operating Margin of 21.8% was met. However, if the targets were not achieved at 100%, the amount of the performance-based RSU award would be reduced in accordance with the same equity sliding scale as the 2012 LTI Program. The Compensation Committee applied the same analysis in determining financial performance against applicable targets that they used in determining the annual incentive compensation awards and the 2012 LTI Program for the named executive officers. As a result, 88% of the performance-based RSUs granted to Mr. Plumeri were earned and Mr. Plumeri received a long-term incentive award value equal to $5,280,000.

In connection with his promotion in January 2012 from CEO of Willis Re to Chairman and CEO of Willis Global, Mr. Hearn received 6,500 time-based RSUs. These RSUs vest in equal tranches on the first, second and third anniversaries of the grant date.

Details of the 2012 equity award grants made to the named executive officers and the awards earned as a result of the Company’s financial performance are contained in the compensation tables “Grant of Plan-Based Awards” and “Outstanding Equity Awards at Fiscal Year End.” Details concerning the employment agreements of the named executive officers are set forth in the sections entitled “Compensation Tables — Joseph Plumeri’s Employment Agreement (2012 CEO)” and “— Other Named Executive Officers’ Employment Agreements.”

Long-term incentive awards that are intended to be “qualified performance-based compensation” under Section 162(m) were granted under the SMIP or under a combination of the SMIP and one of the Company’s equity plans or any sub-plans thereto, including the 2012 Plan, the Willis Group Holdings 2008 Share Purchase and Option Plan (the “2008 Plan”), the 2000 Hilb, Rogal and Hamilton Share Incentive Plan (the “2000 HRH Plan”) and the 2007 Hilb Rogal and Hobbs Share Incentive Plan (the “2007 HRH Plan” and together with the 2012 Plan, the 2008 Plan and the 2000 HRH Plan, the “Plans”).

Further details regarding the changes made to the 2013 long-term incentive compensation program of our CEO and other named executive officers are reflected in Section 2.4, “The Redesign of Our Named Executive Officer Compensation for 2013 in Response to Advisory Vote” and Section 2.5 “Summary Chart of the Components of Our Named Executive Officers Compensation.”

3.3 Perquisites and Other Benefits

The Company does not believe that providing generous executive perquisites is either necessary to attract and retain executive talent or consistent with our pay-for-performance philosophy. Therefore, other than the benefits described in the “Summary Compensation” table, we do not provide perquisites such as personal use of aircraft, excise tax gross-ups, financial planning services, club memberships or vacation homes to our executive officers. Our corporate aircraft use policy permits a guest of an executive officer or director to accompany them on a business flight on Company aircraft if a seat is available and they reimburse the Company the equivalent of a first-class airline ticket.

In order for Mr. Plumeri to exercise stock options or to receive RSUs when they vest under our equity programs, he is required by federal law to file a notification and report form under the Hart–Scott–Rodino Antitrust Improvements Act of 1976. The Compensation Committee determined that the Company should pay the filing fee and associated legal costs, since otherwise Mr. Plumeri would not receive the same benefit from the equity compensation components as other executive officers of the Company. Accordingly, “Other Compensation” for Mr. Plumeri in the “Summary Compensation Table” includes the filing fee paid on his behalf during 2012.

In addition, the Company provides retirement, life insurance and medical benefits to our executive officers to be competitive with the marketplace in which our executive officers operate (which are the same as those provided to other employees in the workplace).

Retirement income is provided to Mr. Plumeri and some other executive officers through our defined benefit retirement plans. The U.S. defined benefit plan was closed to new hires on January 1, 2007 and was frozen on May 15, 2009. Newly hired executive officers only participate in defined contribution plans. The Company also maintains the Willis Pension Scheme (UK), an approved U.K. defined benefit plan. The Willis Pension Scheme (UK) was closed to new members beginning on January 1, 2006. In 2006, it was replaced by a defined contribution plan for new employees. Details of the retirement benefits received by the named executive officers are contained in the compensation tables in the section entitled “Pension Benefits.”

For U.S. employees, a 401(k) Plan is available for saving towards retirement. In order to provide the opportunity to accumulate retirement income and improve retention, the Company reinstated a matching contribution (which had been suspended in recent years) to the 401(k) Plan effective as of January 1, 2011. The matching contribution was made on December 31, 2012 for eligible employees who were still employed by the Company on that date.

We also maintain a deferred compensation plan for certain U.S. employees whose annual salary is in excess of $225,000 that allows them to plan their tax position through a deferral of part of their annual compensation. Messrs. Plumeri and Krauze both currently participate in this plan. The Company may also make certain contributions to the deferred compensation plan on behalf of Mr. Plumeri. As provided in his 2010 employment agreement, the Company contributes $800,000 annually on behalf of Mr. Plumeri to provide him with retirement income. The final installment of the contribution for Mr. Plumeri’s under this plan was paid on April 15, 2013, reflecting a pro-rata payment for 2013.

4.0 Clawback Policy

Under the Company’s clawback policy, the Board, or any of its committees, may to the extent permitted by applicable law, cancel or require reimbursement of any incentive payments or equity-based awards received by an executive officer after December 31, 2008, if and to the extent that (i) the incentive payment or equity award was based on the achievement of Company financial results which are subsequently restated, (ii) the Compensation Committee determines that the executive officer engaged in fraud, negligence or other misconduct that contributed to the need to restate the Company’s financial results and (iii) the incentive payments or equity-based award values made to the executive officer would have been lower if the Company’s results had been properly reported. In such cases, the Company will seek to recover from the executive officer the amount by which the actual incentive payment or equity award for the relevant period exceeded the amount that the executive officer would have received based on the restated results. The Company’s clawback policy is posted on its website under Investor Relations — Corporate Governance.

The Company will comply, and has modified its award agreements to so indicate, with the provisions of the Dodd-Frank Act, and will adopt a revised mandatory clawback policy that will require the Company, in the event of

31

a restatement, to recover from current and former executives any incentive-based compensation, for the three years preceding the restatement, that would not have been awarded under the restated financial statements. The Compensation Committee periodically reviews the Company’s clawback policy and, to ensure full compliance, will propose its final recommendations to the full Board once it has had the benefit of reviewing the SEC’s proposed and final rules for the legislation.

5.0 Executive Officer and Outside Director Share Ownership Guidelines

We maintain share ownership guidelines under which executive officers and outside directors are expected to acquire a meaningful level of share ownership in the Company, so as to further align their interests with those of our shareholders. In February 2013, the Compensation Committee revised the executive officer share ownership guidelines to require them to own shares equivalent in value to a multiple of his or her base salary, as set forth below:

Position	Multiple
Group CEO		6.0 x base salary
Executive Officers Leading Major Business Units and Group CFO		3.0 x base salary
Other Executive Officers		2.0 x base salary

Executives are encouraged to comply with their applicable guideline as soon as practical given their individual circumstances and no later than five years from (i) March 1, 2013 (the date of the implementation of the policy (i.e., March 1, 2018)) or (ii) the date of the executive’s hiring or promotion. The failure to comply with or make reasonable progress towards meeting the share ownership guidelines in a timely fashion will result in the executive being required to retain all net shares acquired by him or her under the exercise of share options or the vesting of RSUs (net of shares surrendered for the payment of the exercise price and any taxes).

For purposes of meeting the executive officer share ownership guidelines, the related value using the three-month average share price of the following shares will be counted towards achieving and maintaining compliance: shares owned outright; shares or units held in Willis broad-based share purchase plans (i.e., the ESPP, UK Sharesave); unvested RSUs and RSUs subject to time-based vesting; and unvested earned performance-based RSUs. Options and unearned performance RSUs are not counted as shares owned for purposes of the guidelines.

Executives are required to retain at least 50% of the net shares received under equity award programs until the ownership guidelines are met.

As discussed below under “Outside Director Compensation,” outside directors are required to hold shares equal to the lesser of 3.5 times the directors’ cash retainer of $100,000 (i.e., $350,000) or 10,000 shares.

6.0 Anti-Hedging Policies

The Company prohibits executive officers and directors from pledging any Company shares, entering into margin accounts, short selling any Company shares, selling shares “against the box” and buying or selling puts or calls relating to Company shares.

7.0 Share Award Policy

The Board of Directors’ has a policy governing the granting of options and other share-based awards under the Company’s Plans.

32

It is the Company’s policy to neither backdate option grants or other share-based awards to take advantage of a lower share price nor to schedule grants of options or other share-based awards before or after specific events to take advantage of anticipated movements in the price of our shares.

It is also the Company’s policy to grant options with an exercise price no less than the closing sales price as quoted on the NYSE on the date of grant, except in the case of any sharesave sub-plans adopted by the Company for non-U.S. taxpayers outside of the U.S., for which the exercise price of the option is set at a 5% or 10% discount off the closing sales price on the date before employees are invited to participate, consistent with past practice to incent employee ownership.

In addition to approving Share-based awards to executive officers, the Compensation Committee is responsible for approving the overall allocation of Share-based awards to the employees of the Company and its subsidiaries and affiliates for the forthcoming year. Implementation of the granting of such awards within the agreed annual plan is delegated to the Share Award Committee consisting of the CEO, the Group Chief Financial Officer and the Group Human Resources Director. The members of the Share Award Committee work closely with the Chairman of the Compensation Committee to ensure that, in particular, the timing of grants is appropriate.

Awards may be made at a time when the Company is in possession of material non-public information, so long as the timing of the award is not motivated by an intention to improperly use any such material non-public information for the benefit of the recipient.

Under this policy, annual share-based awards are authorized by the Compensation Committee and the grant date shall be the date of that meeting or a date specified by the Compensation Committee no later than 30 days following that meeting. Except as directed by the Compensation Committee, share-based awards granted in connection with a new hire, a promotion or the assignment of additional responsibilities to an existing employee or for retention purposes will be considered granted on March 5th, May 10th, August 10th, November 10th or December 5th (or if the applicable grant date is not a trading day, the next trading day) on the date most closely following the month in which such recipient’s employment or promotion or assignment of new responsibilities commenced and such retention award was approved.

8.0 Tax and Accounting Implications

The Compensation Committee considers the anticipated tax treatment to the Company and to the executive officers in its review and establishment of compensation programs and payments. Section 162(m) imposes a limit on the amount the Company may deduct for U.S. tax purposes for compensation paid to our CEO and our three most highly compensated executive officers employed at the end of the year (other than the Chief Financial Officer). However, compensation which qualifies as “performance-based” under Section 162(m) is excluded from the limit if, among other requirements, the compensation is payable only upon the attainment of pre-established, objective performance goals under a plan approved by the Company’s shareholders.

The SMIP, which was approved by shareholders at the 2005 Annual General Meeting, is intended to comply with the provisions of, and to be administered in compliance with the requirements of, Section 162(m). The Company is also authorized to grant equity awards that qualify as “performance-based” compensation under certain of the Company’s Plans.

The SMIP provides for an annual incentive compensation award equal to 5% of the Company’s earnings for the fiscal year, which the Compensation Committee may reduce (but not increase) in its discretion. For this purpose, “earnings” means the Company’s operating income before taxes and extraordinary loss as reported in its audited consolidated financial statements, as adjusted to eliminate the effect of certain events specified in the SMIP. The Compensation Committee also takes other performance metrics into consideration in determining amounts payable under the SMIP (including, among other things, revenue and profit metrics), but the amounts payable under the SMIP may not exceed the amount described above. The Compensation Committee designates the executive officers who participate in the SMIP.

33

The Compensation Committee may consider the following performance criteria when granting performance-based awards: (i) annual revenue, (ii) budget comparisons, (iii) controllable profits, (iv) EPS or Adjusted EPS, (v) expense management, (vi) improvements in capital structure, (vii) net income, (viii) net or gross sales, (ix) operating income (pre- or post-tax), (x) profit margins, (xi) operating or gross margin, (xii) profitability of an identifiable business unit or product, (xiii) return on investments, (xiv) return on sales, (xv) return on stockholders’ equity, (xvi) total return to stockholders, (xvii) assets under management, (xviii) investment management performance, (xix) mutual and other investment fund performance, (xx) cash flow, operating cash flow, or cash flow or operating cash flow per share (before or after dividends), (xxii) price of the shares or any other publicly traded securities of the Company, (xxiii) reduction in costs, (y) return on capital, including return on total capital or return on invested capital, (xiv) improvement in or attainment of expense levels or working capital levels, and (xv) performance of the Company relative to a peer group of companies and/or relevant indexes on any of the foregoing measures.

Interpretations of and changes in applicable tax laws and regulations as well as other factors beyond the control of the Compensation Committee can affect deductibility of compensation and there can be no assurance that compensation paid to our executive officers who are covered by Section 162(m) will be treated as qualified performance-based compensation. Our general policy is to preserve the tax deductibility of compensation paid to the CEO and other named executive officers, including annual incentives and equity awards under the terms of the Company’s Plans. The Compensation Committee reserves the right to use its judgment to authorize compensation payments that may not be deductible when the Compensation Committee believes that such payments are appropriate and in the best interests of the Company, taking into consideration changing business conditions and the performance of its employees.

The Compensation Committee will continue to monitor developments and assess alternatives for preserving the deductibility of compensation payments and benefits to the extent reasonably practicable, consistent with its compensation policies and as determined to be in the best interests of the Company and its shareholders.

It is also the Company’s general policy to deliver equity-based compensation to employees in as tax-efficient a manner as possible, taking into consideration the overall cost to the Company, for which the Company accounts in accordance with FAS 123R.

9.0 Payments on Change of Control and Termination

Historically, the Company has been selective in providing for potential payments relating to a change of control. The Compensation Committee may enter into such agreements when in its business judgment it believes that such payments are appropriate and in the best interests of the Company. No named executive officer is entitled to any automatic payments in connection with a change of control of the Company. However, certain equity awards held by our named executive officers vest in part or in full upon a change of control and the deferred cash awards held by our named executive officers may, in the discretion of the Compensation Committee, become payable upon a change of control. Treatment of equity awards in this manner (as opposed to cash payments that are not automatically accelerated) ensures that our executives are motivated primarily by the needs of the businesses for which they are responsible, rather than circumstances that are outside the ordinary course of business—i.e., circumstances that might lead to the termination of an executive’s employment or that might lead to a change in control of the Company. Generally, this is achieved by assuring our named executive officers that they will receive their equity awards if their employment is adversely affected in these circumstances, subject to certain conditions. We believe that these benefits help ensure that affected executives act in the best interests of our shareholders, even if such actions are otherwise contrary to their personal interests. This is critical because these are circumstances in which the actions of our named executive officers may have a material impact upon our shareholders.

The Company provides severance protection to key employees in limited circumstances primarily where the employee is terminated by the Company without cause or the employee resigns for good reason. The Compensation Committee believes that severance benefits are a necessary component of a competitive compensation program and, in certain cases, are in consideration for an executive’s agreement not to compete. Messrs. Plumeri, Casserley and Hearn are also entitled to enhanced severance benefits in the event their employment is terminated by us without cause or by the executive for good reason in connection with a change of control in order to avoid any associated distractions. The Compensation Committee believes that its use of severance benefits is not significantly different from the severance benefits typically in place at other companies.

34

Joseph Plumeri (2012 CEO)

Mr. Plumeri resigned as the Company’s CEO on January 6, 2013 but will continue to serve as non-executive chairman and as an employee of Willis North America, Inc., a subsidiary of the Company through July 7, 2013.

Change of control provisions were included in Mr. Plumeri’s employment agreement when he originally joined the Company. At that time, the Company was privately owned, predominantly by Kohlberg, Kravis & Roberts (“KKR”). In order to recruit an individual of the right caliber to fill the role of Chairman and CEO of the Company as then existed, and given the range of exit strategies available to KKR, it was considered appropriate at that time to include provisions in his employment agreement which provided protection in the case of a change of control.

During 2009, the Compensation Committee and the Board of Directors determined that it would be in the best interests of the Company to ensure Mr. Plumeri’s continued services as the Company’s Chairman and CEO until July of 2013. In addition, Mr. Plumeri, the Compensation Committee and the Board of Directors agreed that Mr. Plumeri’s prior employment agreement should be updated to reflect the evolution of best pay practices over the last several years. At the time, two members of the Compensation Committee, Sir Roy Gardner and Mr. McCann, participated in all discussions with Mr. Plumeri regarding his employment agreement and were advised during the negotiations by the Compensation Committee’s consultant.

Specifically, it was determined that the provision in Mr. Plumeri’s employment agreement allowing the executive to voluntarily terminate his employment for any reason following a change of control and receive severance payments was inconsistent with best pay practices as well as the Company’s compensation philosophy and objectives. Consequently, the amended employment agreement, which Mr. Plumeri entered into in January 2010, provided that Mr. Plumeri could no longer voluntarily terminate his employment following a “change of control” (as defined in his employment agreement) and receive severance. Instead, it provided that he is eligible to receive severance payments and benefits only if he is involuntarily terminated without “cause” or terminates employment for “good reason” (each as defined in his employment agreement). However, if Mr. Plumeri terminated his employment without “good reason” following a “change of control,” he would be credited with the amount that the Company would have contributed to his deferred compensation benefit account had he remained until the end of his contract of employment, on July 7, 2013. Further information regarding Mr. Plumeri’s employment agreement and details of the change of control and severance provisions are contained in the sections entitled “Compensation Tables — Joseph Plumeri’s Employment Agreement (2012 CEO);” “— Potential Payments to Mr. Plumeri Upon Termination or Change of Control.”

Dominic Casserley (Current CEO)

Under his employment agreement dated as of October 16, 2012, in the event that Mr. Casserley’s employment is terminated by the Company without “cause,” Mr. Casserley resigns for “good reason” (as such terms are defined in his employment agreement) or Mr. Casserley is terminated as a result of the non-renewal of his employment agreement by the Company within the first four years of employment (a “Qualifying Termination”), Mr. Casserley would be entitled to receive severance payments and benefits, including partial service vesting credit (but not performance-vesting credit) for his annual equity-based long-term incentive awards. In the event of a Qualifying Termination within two years following a “change of control” (as such term is defined in his employment agreement), certain of Mr. Casserley’s severance payments would be paid in a lump sum (rather than installments) and Mr. Casserley would receive full service-vesting credit (but not performance-vesting credit) for each of the annual equity-based long-term incentive awards granted to him. Lastly, upon termination of employment (other than for “cause”) concurrent with or following the expiration of the full five-year term of the agreement, Mr. Casserley would be entitled to partial service-vesting credit (but not performance-vesting credit) for each of the annual equity-based long-term incentive awards granted to him and such termination will be treated as retirement for purposes of compensation previously paid or payable to him. Further information regarding Mr. Casserley’s employment agreement and details of the change of control and severance provisions are contained in the section entitled “Compensation Tables — Dominic Casserley’s Employment Agreement (Current CEO).”

35

Other Named Executive Officers

Michael Neborak

In order to attract Mr. Neborak as the new Group CFO, the Company agreed in his employment agreement that all of his earned and unvested RSUs and options shall immediately vest in the event of a Change of Control (as such term is defined in the applicable Plans and/or RSU agreement). In the event Mr. Neborak is involuntarily terminated without “cause” (as such term is defined in his employment agreement) he is eligible to receive severance payments. Mr. Neborak has also entered into a restrictive covenant agreement with the Company that provides, in part, that we may require that Mr. Neborak refrain from working for, engaging or generally having a financial interest in certain of our competitors after the termination of his employment, in exchange for providing severance payments and continued healthcare coverage to him during such non-compete period.

Stephen Hearn

At the same time the Board appointed Mr. Casserley as the Company’s new CEO, it promoted Mr. Hearn to the new role of Deputy CEO. Mr. Hearn has been employed by the Company for almost four years and in January 2012 was promoted to Chairman and CEO of Willis Global, encompassing the Company’s global reinsurance, placement and specialty, operations. The Board believes the combination of Mr. Casserley’s external perspective and broad global experience and Mr. Hearn’s internal perspective and deep industry experience is a powerful partnership to drive the Company’s strategic direction.

On October 16, 2012, in connection with this promotion to Deputy CEO, Mr. Hearn entered into an amended employment agreement which became effective on January 1, 2013. Under the amended contract, in the event that Mr. Hearn’s employment is terminated without “cause” or Mr. Hearn resigns for “good reason” (as such terms are defined in his employment agreement), Mr. Hearn would be entitled to receive severance payments and benefits including partial acceleration of his long-term incentive awards. In the event that Mr. Hearn’s employment is terminated without “cause” or Mr. Hearn resigns for “good reason” within two years following a “change in control” (as such term is defined in his employment agreement), Mr. Hearn would be entitled to receive an enhanced severance payment.

Timothy Wright

On July 19, 2012, Mr. Wright entered into an amendment to his employment agreement which provides that in the event Mr. Wright is terminated by the Company for any reason other than for “cause” (as such term is defined in his amendment), he will be entitled to receive a severance payment.

Victor Krauze

In order to retain the services of Mr. Krauze during the transition from Mr. Plumeri to Mr. Casserley as the Group’s CEO, on October 16, 2012, a Company subsidiary entered into an amendment to Mr. Krauze’s April 8, 2011 promotion letter. Under the amendment, Mr. Krauze is eligible for enhanced severance payments and benefits if before December 31, 2013, he is involuntarily terminated by the Company other than for “good cause” (as such term is defined in the amendment to his promotion letter) or he resigns for “good reason”. “Good reason” in the amendment to his employment agreement means, (i) a material diminution in status, position, authority or duties which in Mr. Krauze’s reasonable judgment is materially inconsistent with and has a material adverse impact on his status, position, authority or duties, (ii) beginning on April 2, 2013 and ending on December 31, 2013, Mr. Krauze’s dissatisfaction with the strategy, policies or operating procedures adopted by Mr. Casserley and (iii) other events constituting good reason. Further, Mr. Krauze’s employment agreement provides that we may require that Mr. Krauze refrain from undertaking any activity deemed to be in competition with the Company for a period of up to 12 months following termination of employment in exchange for monthly payments equivalent to his base salary and continued healthcare coverage to him during the non-compete period. Such payments may be reduced by the amount of any other post-employment payments paid to Mr. Krauze.

Further information regarding Messrs. Neborak, Hearn, Wright and Krauze’s employment agreements and Mr. Neborak’s and Mr. Krauze’s restrictive covenant agreements and details of the applicable termination provisions are contained in the sections entitled “Compensation Tables — Other Named Executive Officers’ Employment Agreements” and “— Potential Payments to Other Named Executive Officers Other than the CEO Upon Termination or Change of Control.”

(1) The Bonus column reflects only that portion of the annual incentive compensation award paid in cash to the named executive officers for services rendered for the relevant fiscal year. Because any RSUs or option awards granted as part of an annual compensation award are granted in March of the year following the one in which services are rendered, these equity awards are reflected in the Share Awards and Option Awards columns for the next year. In 2012, all named executive officers were paid 100% of their annual incentive compensation in cash. In 2010 and 2011, Mr. Plumeri’s annual incentive compensation award was paid 50% in cash and 50% in RSUs. Due to the nature of Mr. Plumeri’s employment agreement, his annual incentive compensation is reflected in the column “Non-Equity Incentive Plan Compensation” discussed in footnote (3) below.

(2) The Share Awards and Option Awards columns include any RSUs or option awards granted in the recently completed fiscal year as part of an annual incentive compensation award for services rendered in the preceding year as well as any other equity awards made during the course of the relevant fiscal year. The actual earned awards are set forth in the footnotes to the “Grant of Plan-Based Awards” table.

For awards subject to performance conditions, the amount included in the table is the full fair value at the grant date based on the probable outcome with respect to the satisfaction of the performance condition consistent with the recognition criteria in FASB ASC Topic 718 (excluding the effect of estimated forfeiture). For more information regarding the equity awards, see the “Grant of Plan-Based Awards” table and the “Outstanding Equity Awards at Fiscal Year End” table.

(3) For 2012, the Non-Equity Incentive Plan column reflects the annual incentive compensation award paid 100% in cash to Mr. Plumeri.

(4) The US Pension share was closed to new hires on January 1, 2007 and frozen on May 15, 2009. The Willis Pension Scheme (UK) was closed to new members beginning on January 1, 2006.

The Change in Pension Value and Nonqualified Deferred Compensation Earnings column includes the aggregate earnings Mr. Plumeri receives under the non-qualified deferred compensation plan, which for 2012 was ($25,741), reflecting investment earnings of $801 offset by Social Security and Medicare taxes totaling $26,542. The Change in Pension Value of $8,460 reflects changes in valuation assumptions required by applicable accounting rules and actuarial standards and a one-year increase in the executive’s age.

(5) For 2012, the All Other Compensation column for the named executive officers consisted of:

a. For Mr. Plumeri, (i) a deferred compensation credit of $800,000 pursuant to the terms of his previous employment agreement, which he receives for each year he continues to be with the Company and which is paid into a non-qualified deferred compensation plan on his behalf, after the payment of Social Security and Medicare taxes, (ii) the $200,000 Hart–Scott–Rodino Antitrust report filing fee and associated legal fees described in the “Compensation Discussion and Analysis” section and (iii) car charges.

b. For Mr. Neborak, the Company’s contribution to his 401(k) Plan.

c. For Mr. Hearn, the Company’s contribution to his defined contribution plan.

d. For Mr. Wright, contributions to a personal pension arrangement set up by Mr. Wright for his own personal benefit. The Company has no ongoing role in the governance or management of the plan and no residual liabilities in respect of it. The contributions made by the Company to the Willis Stakeholder Pension Scheme in respect of Mr. Wright includes $11,621 in lieu of entitlement to a car allowance.

e. For Mr. Krauze, (i) $18,230 tax-gross up for the 2010 calendar year to which he was entitled before his employment contract was amended to eliminate such tax gross-ups and (ii) the Company’s contribution to his defined contribution plan.

(6) Messrs. Hearn and Wright receive their salaries and bonuses in pounds sterling and the above figures have been converted into dollars at the average exchange rate for 2012 (£1:$1.585).

(1) Pursuant to Mr. Plumeri’s employment agreement, it was originally intended that Mr. Plumeri would receive his 2012 annual incentive compensation 50% in cash and 50% in RSUs, as in prior years. The amounts above represent the target, threshold and maximum cash amounts Mr. Plumeri may receive under his employment agreement. In March 2012, Mr. Plumeri and the Compensation Committee agreed to reduce his target payout to 250% of his base salary if 100% of his performance targets were achieved. As a result of Mr. Plumeri’s resignation as CEO in January 2013, the Compensation Committee determined to pay the 2012 annual incentive compensation 100% in cash. The actual cash amount paid to Mr. Plumeri for his 2012 annual incentive compensation is included in the Non-Equity Incentive Plan Column of the “Summary Compensation” table.

(2) As part of Mr. Plumeri’s 2011 annual incentive compensation, time-based RSUs were granted on March 1, 2012 and will vest and settle on July 7, 2013. Dividend equivalents will be paid when the RSUs vest equal to the dividend rate applicable to all record holders on record dates falling between the time of grant and the time of vest.

(3) Under Mr. Plumeri’s employment agreement, performance-based RSUs were granted on May 7, 2012, 50% of which were earned if an Adjusted EPS target for 2012 was met and 50% of the award was earned if an Adjusted Operating Margin target for 2012 was met. If the targets were not achieved at 100%, the amount of the award would be reduced on a sliding scale basis. The target and maximum amounts above reflect both the Adjusted EPS and Adjusted Operating Margins hitting at 100%. The threshold amounts reflect the minimum amount that would be earned if performance conditions were met for only one of the two applicable metrics (i.e., if 90% of either the Adjusted Operating Margin or Adjusted EPS target were met, then 80% of the performance-based RSUs as to the applicable Adjusted Operating Margin or Adjusted EPS target will become earned).

Based on the applicable performance metrics described in the “Compensation Discussion and Analysis — Long Term Incentive Compensation,” 145,374 of the performance-based RSUs were earned. These earned RSUs will vest and settle on July 7, 2013.

(4) Time-based options were granted on December 26, 2012 under the 2012 LTI Program. The options will vest 50% on each of the second and third anniversaries of the grant date.

(5) Performance-based RSUs were granted on December 26, 2012 under the 2012 LTI Program, 50% of which were earned if an Adjusted EPS target for 2012 was met and 50% of the award was earned if an Adjusted Operating Margin target for 2012 was met. If the targets were not achieved at 100%, the amount of the award would be reduced on a sliding scale basis. The target and maximum amounts above reflect both the Adjusted EPS and Adjusted Operating Margins hitting at 100%. The threshold amounts reflect the minimum amount that would be earned if performance conditions were met for only one of the two applicable metrics (i.e., if 90% of either the Adjusted Operating Margin or Adjusted EPS target were met, then 80% of the performance-based RSUs as to the applicable Adjusted Operating Margin or Adjusted EPS target will become earned).

Based on the applicable performance metrics described in the “Compensation Discussion and Analysis—Named Executive Officers’ Annual Compensation — Long Term Incentive Compensation,” the following performance-based RSUs were earned: Mr. Neborak (13,119), Mr. Hearn (28,860), Mr. Krauze (15,743) and Mr. Wright (19,677). Earned RSUs will vest 50% on each of the second and third anniversaries of the grant date.

(6) Time-based RSUs were granted on December 26, 2012 under the 2012 LTI Program. The RSUs will vest 50% on each of the second and third anniversaries of the grant date.

(7) Time-based RSUs were granted on March 1, 2012. The RSUs will vest 33%, 33% and 34% on the first, second and third anniversaries of the grant date, respectively.

Pension Benefits

Willis North America Inc. Pension Plan — The Company maintains a US retirement program, the Willis North America Inc. Pension Plan, a qualified defined benefits plan. This plan provides members with a pension on normal retirement age of 60 or 65 based on the length of service, pensionable remuneration and when they first joined the plan. Participants are 100% vested in the plan after completing five years of service. Employees also become 100% vested if they are participants in the plan and are employed by Company after reaching age 60. The plan was closed to new hires on January 1, 2007 and was frozen on May 15, 2009.

If participants are vested and married, their surviving spouses may be entitled to survivor benefits from the plan, if the participants die before starting retirement benefits. The default death benefit is the survivor portion of a 50% Joint & Survivor annuity commencing at an early or normal retirement date. If participants are active with 10 or more years of service, the death benefit is 50% of the accrued benefit and commences immediately. If participants are age 55 with 10 or more years of service, they may elect an enhanced survivor benefit.

As of December 31, 2012, Mr. Plumeri had approximately 12 years of vesting service. The accrued annual benefit for Mr. Plumeri, payable as a normal-form annuity beginning on January 1, 2013, is $56,184 (Mr. Plumeri is over 65). At this retirement age, the years of vesting service and annual maximum average salary for Mr. Plumeri are approximately 11 years and $202,000, respectively.

As of December 31, 2012, Mr. Krauze had approximately 16 years of vesting service. The accrued annual benefit for Mr. Krauze, payable as a normal-form annuity beginning at age 65 is $62,043. At a retirement age of 65, the years of vesting service and annual maximum average salary for Mr. Krauze are approximately 28 years and $201,001, respectively. Mr. Krauze can retire early with an unreduced accrued benefit as of February 1, 2022, assuming he remains employed to that date.

Also, Willis North America, Inc. has a 401(k) Plan covering its eligible employees and those of its subsidiaries. Shares are available as an investment option to participants in the Willis 401(k) Retirement Savings Plan. In order to provide the opportunity to accumulate retirement income and improve retention, the Company has reinstated a matching contribution (which was suspended in recent years) to the 401(k) Plan effective as of January 1, 2011. The matching contribution was made on December 31, 2012 for eligible employees who were still employed by the Company on that date.

Willis Pension Scheme (UK) — The Company also maintains a U.K. retirement program consisting of the Willis Pension Scheme, an approved defined benefits plan. The Willis Pension Scheme (UK) was closed to new members beginning on January 1, 2006. In 2006, it was replaced by a defined contribution plan for new employees. The Willis Pension Scheme (UK) provides members with a pension of up to two thirds of pensionable remuneration on normal retirement age. Normal retirement age is 65 for all benefits accruing after July 1, 2011. Some rights earned before July 1, 2011 can be drawn at the age of 60 on a reduced basis. Members accrue pension at a rate of 1/50th or 1/60^th of pensionable remuneration, depending on grade and when they first joined the Willis Pension Scheme (UK), in each case subject to a maximum of two-thirds of pensionable remuneration on retirement. Other members may have different accrual rates due to individual circumstances, such as continuation of existing benefits on joining. Members contribute 10% of their pensionable remuneration.

Pensionable remuneration is based on full basic salary less an offset in respect of the U.K. State Pension, currently £5,587, in the case of most members. In addition, pensionable remuneration for members who joined the Scheme after June 1, 1989, is subject to a cap, currently £137,400. On death, pensions based on one half of the members’ pensions are payable to a surviving spouse.

Mr. Hearn and Mr. Wright do not participate in the Willis Pension Scheme because they joined the Company after 2006. Mr. Hearn participates in the Willis UK defined contribution plan and the Willis Stakeholder Pension Scheme, which is a series of individual investment policies established in the names of members and administered by a third party to which the Company contributes. The contributions made by the Company to the Willis Stakeholder Pension Scheme in respect of Mr. Hearn are made at the rate of 12% of basic salary in line with a contractual arrangement transferred from an acquired employer and exceed the standard rates payable to most other associates. Mr. Wright established a personal pension arrangement similar to the Willis UK defined contribution plan to which the Company contributes. The Company has no ongoing role in the governance or management of Mr. Wright’s plan and no residual liabilities in respect of it.

Rest of World — Elsewhere, pension benefits for our employees are typically provided in the country of operation through defined contribution plans.

The following table sets forth the retirement benefits that may be received by the named executive officers that participate in a defined benefit pension scheme:

Name	Plan Name	Number of Years Credited Service (#)		Present Value of Accumulated Benefit ($’000)		Payments During Last Fiscal Year ($)
J. Plumeri	Willis North America Inc. Pension Plan		12		634		—

Non-Qualified Deferred Compensation

The following table sets forth the non-qualified deferred compensation to be received by Mr. Plumeri (the Company’s 2012 CEO) and Mr. Krauze. None of the other named executive officers receives deferred compensation.

Name	Executive Contributions in Last Fiscal Year ($)			Registrant Contributions in Last Fiscal Year ($)		Aggregate Earnings in Last Fiscal Year ($)			Aggregate Withdrawals/ Distributions ($)		Aggregate Balance at Last Fiscal Year End ($)

Joseph Plumeri’s Employment Agreement (2012 CEO)

During 2009, the Compensation Committee and the Board of Directors determined that it would be in the best interests of the Company to ensure Mr. Plumeri’s continued services as the Company’s Chairman and CEO until July of 2013. In addition, Mr. Plumeri, the Compensation Committee and the Board of Directors agreed that Mr. Plumeri’s prior employment agreement should be updated to reflect the evolution of best pay practices over the last several years. At the time, two members of the Compensation Committee, Sir Roy Gardner and Mr. McCann, participated in all discussions with Mr. Plumeri regarding his employment agreement and were advised during the negotiations by the Compensation Committee’s consultant.

On January 6, 2013 Mr. Plumeri resigned as the Group CEO but will continue to serve as non-executive chairman and as an employee of Willis North America, Inc., a subsidiary of the Company. Until his retirement as non-executive chairman and an employee of Willis North America, Inc. on July 7, 2013, all of the terms of Mr. Plumeri’s existing employment agreement dated as of January 1, 2010, will remain in effect, except as amended on October 16, 2012 to reflect his duties, responsibilities and reduced time commitment to the Company as non-executive chairman beginning on January 7, 2013. The rationale for the new arrangements with Mr. Plumeri was to facilitate a seamless transition with the Company’s new CEO, particularly in light of Mr. Plumeri’s long tenure, deep industry knowledge and relationships. The amendment to Mr. Plumeri’s employment agreement also satisfied the requirements for his retirement or earlier resignation to constitute a “mutual retirement” for purposes of Mr. Plumeri’s unvested RSU awards and, as a result, upon Mr. Plumeri’s retirement or his earlier resignation the service requirements for Mr. Plumeri’s RSU awards will be waived.

Under his employment agreement, Mr. Plumeri’s annual base salary of $1,000,000 until his retirement date on July 7, 2013, which has not increased since he joined Willis in October 2000, will be maintained. Similarly, Mr. Plumeri will be eligible to receive a pro-rata annual incentive compensation award for 2013, subject to the achievement of performance targets to be determined by the Compensation Committee. Unlike previous awards, which were generally paid 50% in cash and 50% in RSUs, Mr. Plumeri’s 2012 award and the pro-rata award for 2013 will be paid 100% in cash. Mr. Plumeri’s employment agreement provides that the threshold, target and maximum annual incentive payout percentages for 2012 and 2013 are 250%, 375% and 500% of base salary. Mr. Plumeri will also continue to receive a pro rata portion of the same annual deferred compensation credit of $800,000, the last installment of which was contributed on April 15, 2013, subject to his continued employment.

In consideration for Mr. Plumeri complying with best pay practices when he amended his agreement in January 2010, at the time the Compensation Committee and Board provided that he would receive a grant of RSUs in 2010 that would vest only upon the achievement of performance and time-based criteria to be determined by the Compensation Committee. The agreement provided that the RSUs would have a grant date value of $6,000,000 and would vest in equal parts over a three-year period. At the time of the execution of the 2010 employment agreement, it was the expectation and intent of the Compensation Committee to award Mr. Plumeri grants of comparable value and containing comparable terms in 2011 and 2012, subject to the Compensation Committee’s good faith evaluation of changes in circumstances of the Company, the performance of the Company and the performance of Mr. Plumeri that justifies as an alternative vehicle or amount of grant. Accordingly, a similar $6,000,000 grant of performance-based RSUs was made in 2011 and 2012. Mr. Plumeri will not be entitled to receive a Long-Term Incentive award during 2013.

The employment agreement also contains non-competition, non-solicitation and confidentiality covenants.

Further information regarding the change of control and severance provisions in Mr. Plumeri’s employment agreement are contained in the section entitled “Compensation Tables—Potential Payments to Mr. Plumeri Upon Termination or Change of Control.”

Dominic Casserley’s Employment Agreement (Current CEO)

In negotiating the agreement with Mr. Casserley, the Company considered, among other things, the Company’s peer group compensation, current market practice regarding CEO pay, ISS and shareholder concerns, pay-for-performance concerns, the Committee’s policy to limit the grants of guaranteed compensation, internal executive compensation practices and the opportunity to split the roles of Chairman of the Board and CEO. These considerations were balanced with the fact that the Company needed to provide competitive pay to attract a high caliber candidate.

On October 16, 2012, Mr. Casserley executed an employment agreement with a subsidiary of the Company. The employment agreement has an initial term ending on December 31, 2015 and will automatically renew for up to two additional

47

one-year renewal terms, unless either party provides notice of nonrenewal at least 90 days prior to the end of the initial term or first renewal term, as applicable. Upon a “change of control” (as such term is defined in his employment agreement) the term will automatically extend until and expire upon the second anniversary of the “change of control” or, if later, December 31, 2015. Mr. Casserley’s agreement provides for him to be paid, beginning as of his commencement of employment with the Company on January 7, 2013: (i) an annual base salary of $1,000,000, (ii) an annual incentive award with a target value of 225% of his base salary (i.e., $2,250,000), a maximum value of 400% of his base salary (i.e., $4,000,000), and a lesser value for below target performance as may be established by the Board or the Compensation Committee, such annual incentive compensation awards described in further detail below, (iii) an annual equity-based long-term incentive award of 525% of base salary (i.e., $5,250,000) at target, and upon such other terms and conditions as may be established by the Board or the Compensation Committee for officers generally, (iv) reimbursement of his and his family’s relocation costs to the New York metropolitan area from London, England and, following his termination of employment with the Company other than for “cause” (as such term is defined in his employment agreement), his and his family’s return to the London metropolitan area, (v) employee benefits as are provided generally to other similarly-situated senior management employees of the Company, the use of a car and driver at his principal office location and the use of private aircraft owned or leased by the Company for business travel in accordance with the Company’s policy, and (vi) an employment commencement transition award of $1,500,000 to be paid after the completion of one year of service (i.e., January 7, 2014), 50% of which is subject to repayment if Mr. Casserley resigns without “good reason” (as such term is defined in his employment agreement) prior to the completion of two years of service.

With respect to Mr. Casserley’s annual incentive award, if Mr. Casserley is entitled to an annual incentive award exceeding $1,000,000 in respect of the Company’s 2013 fiscal year, then the first $1,000,000 will be paid in cash and any amounts exceeding $1,000,000 up to $2,500,000 will be paid in the form of equity-based awards, with one-third being immediately vested by reason of his completion of one year of service and the remainder subject to vesting on the second and third anniversaries of Mr. Casserley’s employment commencement date if Mr. Casserley is employed by the Company on each of the anniversary dates. One-half of such equity-based awards will be in the form of options to purchase ordinary shares of the Company, and one-half of such equity-based awards will be in the form of RSUs.

In the event that Mr. Casserley’s employment is terminated by the Company without “cause,” Mr. Casserley resigns for “good reason” or Mr. Casserley is terminated as a result of the non-renewal of his employment agreement by the Company within the first four years of employment (a “Qualifying Termination”), Mr. Casserley would be entitled to the following benefits: (i) an amount equal to two times the sum of his annual base salary and target annual incentive award, payable in installments over 24 months (the “Severance Payment”), (ii) a pro-rata portion of his annual incentive award for the year in which the termination of employment occurs, based on actual performance, payable at the same time that annual incentive compensation awards are payable generally, (iii) payment of the employment commencement transition award described above, to the extent unpaid, (iv) continued medical coverage at the active employee rate for Mr. Casserley, his spouse and then covered dependents for up to 18 months, (v) two years of service-vesting credit (but not performance-vesting credit) for one half of the annual equity-based long-term incentive awards granted to him during the first three years of service, (vi) one year of service-vesting credit (but not performance-vesting credit) for the remainder of the annual equity-based long-term incentive awards granted to him, (vii) each vested stock option held by Mr. Casserley will remain exercisable for three years following the termination date or, if earlier, the normal expiration date of the stock option, and (viii) accrued benefits including any annual incentive compensation awards earned but unpaid for any completed fiscal year. For purposes of determining the service-vesting credit described above each annual equity-based long-term incentive award will be deemed to have been granted not later than April 30th of the year of grant and vest at a rate not greater less than 1/3rd per year on each of the first three anniversaries of the date of grant.

In the event of a Qualifying Termination within two years following a “change of control,” Mr. Casserley would be entitled to the severance benefits described above except that the Severance Payment would be paid in a lump sum and Mr. Casserley would receive full service-vesting credit (but not performance-vesting credit) for each of the annual equity-based long-term incentive awards granted to him.

Lastly, upon termination of employment (other than for “cause”) concurrent with or following the expiration of the full five year term of his employment agreement, Mr. Casserley would be entitled to the following benefits: (i) two years of service-vesting credit (but not performance-vesting credit) for each of the annual equity-based long-term incentive awards granted to him, (ii) each vested stock option held by Mr. Casserley will remain exercisable for three years following the termination date or, if earlier, the normal expiration date of the stock option and (iii) such termination will be treated as retirement for purposes of compensation previously paid or payable to him. As described above, for purposes of determining the service-vesting credit described above each annual equity-based long-term incentive award will be deemed to have been granted no later than April 30th of the year of grant and vest at a rate not greater less than 1/3rd per year on each of the first three anniversaries of the date of grant.

The agreement also contains non-competition, non-solicitation and confidentiality covenants.

Other Named Executive Officers’ Employment Agreements

Each of the other named executive officers’ have an employment agreement with a subsidiary of the Company. The material economic terms of such agreements are described below. Each of the agreements also contains non-competition, non-solicitation and confidentiality covenants.

Further information regarding the change of control and severance provisions in Messrs. Neborak, Hearn, Wright and Krauze’s employment and restrictive covenant agreements are contained in the section entitled “Compensation Tables—Potential Payments to Other Named Executive Officers Other than the CEO Upon Termination or Change of Control.”

Michael Neborak

Mr. Neborak’s employment agreement effective as of July 6, 2010 provides for an annual base salary of $500,000, which the Committee increased to $600,000 based on the results of a market review, and an annual incentive award with a target value equal to 100% of his base salary. The employment agreement does not have a fixed term. In the event Mr. Neborak is terminated without “cause,” he will receive severance pay equal to 12 months of base salary. The Company has also entered into a separate restrictive covenant agreement with Mr. Neborak effective as of August 2, 2010, which provides, in part, that we may require that Mr. Neborak refrain from undertaking any activity deemed to be in competition with the Company for a period of up to 12 months following termination of employment, in exchange for monthly payments equivalent to his base salary and the provision of continued medical coverage during such period.

Stephen Hearn

Under Mr. Hearn’s employment agreement that remained in effect until December 31, 2012, he was entitled to (i) an annual base salary of £500,000 (or $792,500) and (ii) an annual incentive compensation award with a target value of 175% of his base salary, provided that his annual incentive compensation award in respect of the Company’s 2012 fiscal year to be no less than 150% of his base salary. Pursuant to this agreement, in 2012, Mr. Hearn also received 6,500 time-based RSUs as a result of his promotion to Chairman and CEO of Willis Global in early 2012. Pursuant to this agreement, if Mr. Hearn was terminated by the Company for any reason other than for Cause (as defined in such employment agreement), he was entitled to receive an amount equal to his contractual notice pay due to him (i.e., 12 months base salary) and an amount equal to his target annual incentive compensation award at the time of his termination.

At the same time the Board appointed Mr. Casserley as the Company’s new CEO, it promoted Mr. Hearn to the new role of Deputy CEO. Mr. Hearn has been employed by the Company for almost four years and in January 2012 was promoted to Chairman and CEO of Willis Global, encompassing the Company’s global reinsurance, placement and specialty, operations. The Board believes the combination of Mr. Casserley’s external perspective and broad global experience and Mr. Hearn’s internal perspective and deep industry experience is a powerful partnership to drive the Company’s strategic direction.

In connection with his promotion to Deputy CEO, on October 16, 2012, Mr. Hearn entered into an amended employment agreement which, when it became effective on January 1, 2013, provides (i) an annual base salary of £530,000 ($840,050), (ii) an annual incentive award with a target value of 200% of his base salary (subject to his prior employment agreement that provided for his annual incentive award in respect of the Company’s 2012 fiscal year to be no less than 150% of his base salary), and (iii) an annual long-term incentive award of 260% of his base salary at target. The employment agreement does not have a fixed term. Pursuant to Mr. Hearn’s amended employment agreement, if Mr. Hearn’s employment is terminated by the Company without Cause or by the executive for Good Reason, he would be entitled to: (i) an amount equal to 150% of the sum of his annual base salary and target annual incentive award, which amount will be offset against any pay provided during the 12-month notice period set forth in the employment agreement or any pay in lieu of notice and will be payable in a lump sum, (ii) a pro-rata portion of his annual incentive award for the year in which the termination of employment occurs, based on actual performance, payable at the same time that annual incentive compensation awards are payable generally, (iii) any annual incentive compensation awards earned but unpaid for any prior fiscal year, and (iv) continuation of group medical coverage at the same rate that is applicable to active senior executive officers.

49

Timothy Wright

Mr. Wright’s employment agreement, dated as of December 17, 2007 and as amended July 19, 2012, provides that Mr. Wright, who originally joined the Company as the Group Chief Operating Officer and currently serves as the CEO of Willis International, is entitled to an annual base salary of £405,000 (or $641,925) and an annual incentive award with a target value equal to 175% of his base salary. As a result of an increase in his responsibilities related to his promotion to CEO of Willis International, Mr. Wright received an increase in his annual base salary to £500,000 (or $792,500). The employment agreement does not have a fixed term. In the event Mr. Wright’s employment is terminated without “Cause” (as defined in his employment agreement), he will receive severance pay equal to the sum of his annual base salary and target annual incentive compensation award at the time he is served with notice of termination.

Victor Krauze

Mr. Krauze’s employment agreement, effective as of December 3, 2010, and promotion letter, dated as of April 8, 2011, provide for a base salary of $625,000 which the Committee increased to $700,000 in response to market conditions. The Company may terminate his employment agreement at any time by providing him 30 days’ prior written notice. In the event he is terminated without “good cause” (as defined in the promotion letter), he will receive severance pay equal to 12 months of base salary, an amount equal to 12 months of COBRA medical coverage premiums and, on or before March 15, 2013, any AIP award for the 2012 performance period. Further, the agreements provide that if we desire Mr. Krauze to refrain from undertaking any activity deemed to be in competition with the Company for a period of up to 12 months following termination of employment, the Company will make monthly payments equivalent to his base salary. Such payments may be reduced by the amount of any other post-employment payments paid to Mr. Krauze, including any severance payments paid to him in connection with a termination without Good Cause.

In order to retain the services of Mr. Krauze during the transition from Mr. Plumeri to Mr. Casserley as the Company’s CEO, on October 16, 2012, a Company subsidiary entered into an amendment to Mr. Krauze’s April 8, 2011 promotion letter. Pursuant to the amendment, Mr. Krauze is eligible for enhanced severance payments and benefits if before December 31, 2013, he is involuntarily terminated by the Company other than for “good cause” or he resigns for “good reason.” The employment agreement does not have a fixed term.

Potential Payments to Mr. Plumeri Upon Termination or Change of Control

The following table shows the estimated payments and benefits that our CEO would have received if his employment had terminated or a Change of Control (defined below) occurred on December 31, 2012.

Joseph J. Plumeri	Severance ($)		Deferred Compensation ($)		Accrued Amounts ($)(4)		Total Payments on Termination ($)		Intrinsic Value of Unvested Share-Based Awards ($)(5)

(1) Mr. Plumeri’s employment agreement provided that if he was terminated by the Company without Cause or by himself for Good Reason he would be entitled to a lump sum payment equal to $4,000,000 in addition to any accrued benefits. The accrued benefits included: unpaid salary and vacation pay; any bonus due as a result of actual performance but not yet paid for any completed financial year; a pro rata bonus for the year in which the termination occurs based on the performance achieved in that year; amounts due under medical, life insurance, disability and pension plans; and reimbursable business expenses.

He would also have credited to his deferred compensation benefit account the amounts he would have received had he remained until the end of the term of his employment agreement (July 7, 2013). On departure, the full amount accrued under the deferred compensation plan would become payable.

Further, the RSUs granted to Mr. Plumeri on May 3, 2010, May 2, 2011 and March 1, 2012 would vest in full and the service requirements for the RSUs granted to Mr. Plumeri on May 7, 2012 would be waived.

The table above shows the amount Mr. Plumeri would have received had termination taken place on December 31, 2012, and assuming the Board has exercised its discretion to waive the performance requirements applicable to the RSUs granted to Mr. Plumeri on May 7, 2012.

(2) Mr. Plumeri’s employment agreement provided that in the event the Company was subject to a Change of Control and Mr. Plumeri’s employment was terminated by the Company (or a successor company) without Cause or by himself for Good Reason within six months prior to or within 24 months following such Change of Control, Mr. Plumeri would receive a payment equal to two times the sum of his base salary and target annual bonus during the year in which the termination of employment occurs. Mr. Plumeri would have also continued to be entitled to receive the accrued benefits described in (1) above and he would have credited to his deferred compensation benefit account the amounts he would have received had he remained until the end of the term of his employment agreement (July 7, 2013). On departure, the full amount accrued under the deferred compensation plan would become payable.

Further, in the event the Company was subject to a Change of Control and Mr. Plumeri’s employment was terminated by the Company without Cause or by him for Good Reason, the RSUs granted to Mr. Plumeri on May 3, 2010, May 2, 2011, March 1, 2012 and May 7, 2012 would vest in full.

The table above shows the amount Mr. Plumeri would have received had termination taken place on December 31, 2012 by reason of Change of Control, including the value of Mr. Plumeri’s unvested RSUs.

51

(3) Where the employment was terminated by the Company for any reason other than as described in (1) and (2) above, including Disability, mutual retirement and retirement, Mr. Plumeri would be entitled to receive the accrued benefits as described in (1) above including the right to receive the full amount accrued under the deferred compensation plan, provided that in the event of a termination for Cause the executive would not be entitled to a pro-rata bonus. Pursuant to Mr. Plumeri’s amended employment agreement, if he terminated his employment without Good Reason following a Change of Control, he would have credited to his deferred compensation benefit account the amounts he would have received had he remained until the end of the term of his employment agreement (July 7, 2013). On departure the full amount accrued under the deferred compensation plan would become payable.

In the event Mr. Plumeri’s termination was due to death, Disability or mutual retirement, the RSUs granted to Mr. Plumeri on May 3, 2010, May 2, 2011 and March 1, 2012 would vest in full and the service requirements for the RSUs granted to Mr. Plumeri on May 7, 2012 would be waived.

The table above shows the amount Mr. Plumeri would have received had termination taken place on December 31, 2012 for any reason other than described in (1) and (2) above, except for Cause, and assuming the Board exercised its discretion to waive the performance requirements applicable to the RSUs granted to Mr. Plumeri on May 7, 2012.

(4) It has been assumed for this calculation that the Board, through the Compensation Committee, would have determined that Mr. Plumeri be paid a cash award in an amount equal to his full 2012 annual incentive award. The above amount reflects the actual cash amount paid to Mr. Plumeri for his 2012 annual incentive compensation as reflected in the Non-Equity Incentive Plan Column of the “Summary Compensation” table.

(5) In addition to the above, it had been agreed that Mr. Plumeri would still retain the benefit of the Company’s directors and officers insurance relating to his services for the period up to and including his date of departure where termination of employment was without Cause or for Good Reason or Change of Control. Also, under the U.S. Pension Plan, in the event of termination of employment for any of the above reasons, Mr. Plumeri would receive the same benefit as other plan participants terminated for similar reasons. For more information please see “Executive Compensation — Compensation Discussion and Analysis — Pension Benefits.”

(6) The occurrence of a Change of Control would not trigger any cash payments to Mr. Plumeri, however, the performance requirements applicable to Mr. Plumeri’s RSUs, to the extent not already achieved, would be waived. In addition, upon a Change of Control, the Board would have had discretion to waive the service requirements applicable to Mr. Plumeri’s RSU awards. For the purpose of this section, it has been assumed that such discretion had been exercised.

(7) The terms “Cause,” “Good Reason,” “Disability,” “mutual retirement,” and “retirement” are used as defined in Mr. Plumeri’s employment agreement. The term “Cause” includes, among other things, conviction of a felony, willful and continuous disregard for, or serious or persistent breach of material duties and responsibilities, gross negligence or any other form of gross misconduct. The term “Good Reason” includes, among other things, any material diminution of duties, responsibilities or authority, or the assignment to Mr. Plumeri of any duties materially inconsistent with his position or any material breach of his contract of employment by the Company.

52

(d) a merger, consolidation or other corporate transaction of the Company (a “Transaction”) such that the shareholders of the Company immediately prior to such Transaction do not own more than 50 percent of the aggregate ordinary voting power of the surviving entity (or its parent) immediately after such Transaction in approximately the same proportion to each other as immediately prior to the Transaction;

(e) the sale of all or substantially all of the assets of the Company; or

(f) approval by the Company’s shareholders of a plan of liquidation or dissolution of the Company.

(1) Mr. Krauze entered into an amendment to his promotion letter dated October 16, 2012 which provides that in the event Mr. Krauze’s employment is terminated by the Company without Good Cause or by the executive for Good Reason prior to December 31, 2013, all earned and outstanding equity and long-term incentive awards granted to him through calendar year 2012 will vest in full. “Good Cause” is defined as (i) gross neglect of duties, (ii) conviction of a felony, (iii) dishonesty, embezzlement, or fraud by the executive in connection with his employment, (iv) the issuance of any final order for the executive’s removal as an associate of the Company by any state or federal regulatory agency, (v) material willful breach of the “Confidential Information and Work for Hire” or “Employee Loyalty, Non-competition and Non-solicitation” provisions in the executive’s employment agreement, (vi) any material breach of the Company’s Code of Ethics, or (vii) failure to maintain any insurance or other license necessary to the performance of the executive’s duties. “Good Reason” is defined as (i) a material diminution in status, position, authority or duties which in Mr. Krauze’s reasonable judgment is materially inconsistent with and has a material adverse impact on his status, position, authority or duties, (ii) a material reduction in base salary, (iii) a material breach by the Company of any material provision in Mr. Krause’s employment agreement or promotion letter and (iv) beginning on April 2, 2013 and ending on December 31, 2013, Mr. Krauze’s dissatisfaction with the strategy, policies or operating procedures adopted by the then CEO of the Company.

Mr. Hearn’s employment agreement that was in effect on December 31, 2012 did not provide for the acceleration of his equity or long-term incentive awards upon a termination of employment for any reason. However, Mr. Hearn entered into an amended employment agreement on October 16, 2012 that was effective on January 1, 2013 which provides that in the event Mr. Hearn’s employment is terminated by the Company without Cause or by the executive for Good Reason, any options, restricted shares, deferred cash or other long term incentive awards due to vest during the twelve month period following the termination date will vest on the termination date. “Cause” is defined as (i) gross and or chronic neglect of duties, (ii) conviction of an offence involving moral turpitude, (iii) dishonesty, embezzlement, fraud or other material willful misconduct in connection with employment, (iv) the issuance of any final order for removal as an associate or officer of the Company by any regulatory authority, (v) violation of any obligation or confidence, fiduciary duty, duty of loyalty or other material obligation owed to the Company in any employment or other agreement with the Company or implied as common law, (vi) material breach of the Company’s code of ethics, or (vii) failure to maintain any insurance or license necessary for the performance of duties to the Company. “Good Reason” is defined as (i) a reduction in base salary or a material adverse reduction in benefits (other than (a) in the case of base salary a reduction offset by an increase in bonus opportunity upon the attainment of reasonable performance goals or (b) a general reduction in compensation or benefits affecting a broad group of employees), (ii) a material adverse reduction in principal duties and responsibilities or (iii) a significant transfer away from his primary service area or primary workplace other than as permitted by existing service contracts.

The Board may, in its discretion, accelerate each of the unvested option, RSU and deferred cash awards held by Messrs. Neborak, Hearn and Wright upon a termination of employment by the Company without cause.

For purposes of this section, it has been assumed that the Company has exercised its discretion to fully vest the option, RSU and deferred cash awards (at the target level of achievement) held by Messrs. Neborak, Hearn and Wright. The table above shows the intrinsic value of all unvested option, RSU and deferred cash awards held by the executives as of December 31, 2012.

(2) Mr. Neborak entered into an employment agreement with the Company dated July 6, 2010. The agreement provides that in the event his employment is terminated by the Company without Cause, the executive will receive severance pay equal to 12 months of base salary. “Cause” is defined as (i) gross and or chronic neglect of duties, (ii) conviction of a felony or misdemeanor involving moral turpitude, (iii) material willful dishonesty, embezzlement, fraud or other material willful misconduct in connection with employment, (iv) the issuance of any final order for removal as an associate of the Company by any state or federal regulatory agency, (v) violation of the restrictive covenant provisions in an employment agreement or other agreement with the Company, (vi) material breach of any material duty owed to the Company, including, without limitation the duty of loyalty, (vii) material breach of any other material obligations under an employment or other agreement with the Company, (viii) material breach of the Company’s code of ethics, (ix) failure to achieve reasonable performance goals as specified by the Company or (x) failure to maintain any insurance or license necessary for the performance of duties to the Company.

55

Mr. Krauze entered into an amendment to his promotion letter dated October 16, 2012 which provides that in the event Mr. Krauze’s employment is terminated by the Company without Good Cause or by the executive for Good Reason (each as defined in footnote 1 above) prior to December 31, 2013, the executive will receive (i) 12 months of base salary and medical benefit continuation, (ii) payment of his annual incentive award for the 2012 fiscal year, subject to the achievement of the performance goals established by the Compensation Committee and (iii) a waiver of the repayment obligations applicable to his cash retention awards.

Mr. Hearn’s employment agreement that was in effect on December 31, 2012 provided that if Mr. Hearn was terminated by the Company for any reason other than for Cause (as defined in footnote 1 above), he was entitled to receive an amount equal to his contractual notice pay due to him (i.e., 12 months base salary) and an amount equal to his target annual incentive compensation award at the time of his termination. Mr. Hearn entered into an amended employment agreement on October 16, 2012 that was effective on January 1, 2013 which provides that in the event Mr. Hearn’s employment is terminated by the Company without Cause or by the executive for Good Reason, he would be entitled to: (i) an amount equal to 150% of the sum of his annual base salary and target annual incentive award, which amount will be offset against any pay provided during the 12-month notice period set forth in the employment agreement or any pay in lieu of notice and will be payable in a lump sum, (ii) a pro-rata portion of his annual incentive award for the year in which the termination of employment occurs, based on actual performance, payable at the same time that annual incentive compensation awards are payable generally, (iii) any annual incentive compensation awards earned but unpaid for any prior fiscal year, and (iv) continuation of group medical coverage at the same rate that is applicable to active senior executive officers.

Mr. Wright entered into an amendment to his employment agreement dated July 19, 2012 which provides that in the event he is terminated by the Company for any reason other than for Cause (as defined in footnote 1 above with respect to Mr. Hearn), he will be entitled to receive an amount equal to the sum of his annual base salary and target annual incentive compensation award at the time he is served with notice of termination, which amount will be offset against any pay provided during the six-month notice period set forth in the employment agreement or any pay in lieu of notice and will be payable in a lump sum.

(3) The occurrence of a Change of Control will not trigger any automatic cash payments to Messrs. Neborak, Krauze, Hearn and Wright however, pursuant to his amended employment agreement that was effective on January 1, 2013, upon a termination of employment by the Company without Cause within two years following a Change of Control, Mr. Hearn is entitled to an enhanced severance payment. The enhanced severance payment is equal to 200% (rather than 150%) of the sum of his annual base salary and target annual incentive award, which amount will be offset against any pay provided during the 12-month notice period set forth in his employment agreement or any pay in lieu of notice. Further, the deferred cash awards held by the executives may, in the discretion of the Compensation Committee, vest and become payable. Further, as described below, certain option and RSU awards held by the executives will vest.

The amounts payable to Messrs. Neborak, Krauze, Hearn and Wright in respect of termination of employment on December 31, 2012 in connection with a Change of Control would be calculated on the same basis described in Termination by the Company without Cause above.

Mr. Neborak’s employment agreement provides that in the event of Change of Control all of his RSUs and options will immediately vest in full.

The option award granted to Mr. Krauze on May 6, 2008, the option award granted to Mr. Hearn on November 3, 2008 and the performance-based option award granted to Mr. Wright on September 1, 2008 automatically vest in full upon the occurrence of a Change of Control pursuant to the Company’s 2008 Plan, to the extent such awards are not assumed or substituted. In the event those option awards are assumed or substituted, such options generally vest in full upon a participant’s termination of employment occurring within 24 months following the Change of Control.

All other RSU and option awards may vest upon the occurrence of a Change of Control, in the sole discretion of the Board.

For purposes of the option, RSU and deferred cash awards, “Change of Control” is defined as (i) the acquisition of ownership, directly or indirectly, beneficially or of record, by any person or group (within the meaning of the Exchange Act and the rules of the SEC thereunder as in effect on the date hereof) of the ordinary shares of the Company representing more than 50% of the aggregate voting power represented by the issued and outstanding ordinary shares of the Company; or (ii) occupation of a majority of the seats (other than vacant seats) on the Board of the Company by persons who were neither (a) nominated by the Company’s Board nor (b) appointed by directors so nominated.

56

For purposes of Mr. Hearn’s amended employment agreement “Change of Control” is defined as: (i) the acquisition of ownership, directly or indirectly, beneficially or of record, by any person or group (within the meaning of the Exchange Act and the rules of the SEC thereunder as in effect on the date hereof) of equity interests representing more than thirty (30%) of the aggregate voting power represented by the issued and outstanding equity interests of the Company; occupation of a majority of the seats (other than vacant seats) on the Board of the Company by persons who were neither (a) nominated by the Company’s Board nor (b) appointed by directors so nominated; (iii) a merger, consolidation or other corporate transaction of the Company such that shareholders of the Company immediately prior to such transaction do not own more than fifty percent (50%) of the aggregate ordinary voting power of the surviving entity (or its parent) immediately after such transaction in approximately the same proportion to each other as immediately prior to the transaction; or (iv) the sale of all or substantially all of the assets of the Company.

For purposes of this section it has been assumed that the Company has exercised its discretion to fully vest the option, RSU and deferred cash awards (at the target level of achievement) held by Mr. Neborak, Krauze, Hearn and Wright to the extent that such awards do not automatically vest in full. The table above shows the intrinsic value of all unvested option, RSU and deferred cash awards held by the executives as of December 31, 2012.

(4) The unvested option, RSU and deferred cash awards held by Messrs. Neborak, Krauze, Hearn and Wright each vest in full upon a termination of employment due to death or permanent disability; provided, that, performance-based option and deferred cash awards only vest to the extent that performance targets have been achieved on the date of termination of employment. In addition, the Board, in its sole discretion, may accelerate the vesting of all option, RSU and deferred cash awards upon a termination of employment due to retirement.

For purposes of this section it has been assumed that the Company has exercised its discretion to fully vest the option, RSU and deferred cash awards (at the target level of achievement) held by Messrs. Neborak, Krauze, Hearn and Wright to the extent that such awards do not automatically vest in full. The table above shows the intrinsic value of all unvested option, RSU and deferred cash awards held by the executives as of December 31, 2012.

(5) Mr. Neborak entered into restrictive covenant agreements with the Company, effective on August 2, 2010. The agreement provides, in part, that for a period of 12 months directly following his termination of employment for any reason the executive must refrain from working for, engaging or generally having a financial interest in certain of the Company’s competitors. During the non-compete period the Company is obligated to make payments to the officer equal to the base salary payments the executive would have received if he had remained in the Company’s employ during such period. In addition, the Company is required to pay for the cost of the officer’s medical coverage during the non-compete period. The Company may elect to shorten the non-competition period for Mr. Neborak, in which case the Company would only be obligated to provide the officer with the base salary payments and medical benefits described above during the shortened non-compete period.

Mr. Krauze’s employment agreement and promotion letter similarly provide that for a period of up to 12 months directly following Mr. Krauze’s termination of employment for any reason the executive must refrain from working for, engaging or generally having a financial interest in certain of the Company’s competitors. During the non-compete period the Company is obligated to make payments to Mr. Krauze equal to the base salary payments the executive would have received if he had remained in the Company’s employ during such period. In addition, the Company is required to pay for the cost of the officer’s medical coverage during the non-compete period. Such payments may be reduced by the amount of any other post—employment payments paid to Mr. Krauze, including any severance payments paid to him in connection with a termination without Good Cause or for Good Reason (each as defined in footnote 2 above). Further, the Company may elect to shorten the non-competition period, in which case the Company would only be obligated to provide Mr. Krauze with the base salary payments described in this footnote 5 during the shortened non-compete period.

The table above shows the payments the officer would have received had a termination of employment taken place on December 31, 2012, assuming that payments and benefits were provided for the full 12 month non-compete period.

(6) The occurrence of a Change of Control will not trigger any automatic cash payments to Messrs. Neborak, Krauze, Hearn and Wright. However, as described in Termination by the Company on Change of Control above, certain option and RSU awards held by the executives automatically vest in full upon the occurrence of a Change of Control and the deferred cash and all other option and RSU awards held by the executives may vest upon the occurrence of a Change of Control, in the sole discretion of the Board.

57

For the purpose of this section, it has been assumed that the Company has exercised its discretion to fully vest the option, RSU and deferred cash awards (at the target level of achievement) held by Messrs. Neborak, Krauze, Hearn and Wright to the extent that such awards do not automatically vest in full. The table above shows the intrinsic value of all unvested option, RSU and deferred cash awards held by the executives as of December 31, 2012.

(7) Messrs. Hearn and Wright receive their salaries and annual incentive compensation awards in pounds sterling. The dollar figures shown have been calculated at the exchange rate as at December 31, 2012 (£1: $1.625).

Compensation Risk Analysis

In the first quarter of 2010, at the Compensation Committee’s request, its independent Compensation Consultant at the time, Frederick W. Cook & Co., worked with management to conduct a risk assessment of the Company’s compensation programs. This assessment included an inventory of incentive compensation plans then in place at the Company, a review of the design and features of the Company’s compensation programs with key members of management responsible for such programs and an assessment of program design and features relative to compensation risk factors.

With assistance from the Company’s Director of Risk, Frederick W. Cook & Co., also reviewed the Company’s risk profile and related risk management processes and the findings of the compensation risk assessment to determine if any material risks were deemed to be likely to arise from the Company’s compensation policies and programs and to determine whether these risks would be reasonably likely to have a material adverse effect on its business. The determination, which was reviewed and affirmed by management and the Compensation Committee, was that the Company’s pay plans and policies were not reasonably likely to have a material adverse effect on the Company. In the first quarter of 2011, this conclusion was reaffirmed.

In 2012 and 2013, at the request of the Compensation Committee, Towers Watson (its current independent Compensation Consultant) reviewed the risk assessment conducted by the previous Compensation Consultant and confirmed that the methodology used in that assessment remained valid. Towers Watson has worked with Willis to review its compensation programs and to determine if they had materially changed from the time of the initial risk assessment. As a result of this review, Towers Watson found that the only material change that had occurred was the removal in 2012 of the repayment obligation required under certain cash retention awards under Willis’ annual incentive programs. However, Towers Watson concluded that this action did not pose additional compensation risk because the repayment feature originally had been added to address retention risk versus organizational risk. Accordingly, Towers Watson determined that the 2010 risk assessment findings remain applicable. The Compensation Committee reviewed and affirmed this determination and further commissioned a full risk review of the Company’s compensation programs in 2014.

Outside Director Compensation

In 2012, all outside directors (i.e., all directors other than Mr. Plumeri), received an annual cash retainer fee of $100,000. In addition, (i) the Chairman of the Compensation Committee, the Chairman of the Governance Committee and the Chairman of the Risk Committee each received an annual cash fee of $20,000; (ii) the Chairman of the Audit Committee received an annual cash fee of $30,000; and (iii) the other members of the Audit Committee received an annual cash fee of $10,000. The Presiding Independent Director received an annual cash fee of $35,000. In 2012, the Board also authorized a one-time special cash fee of $30,000 for each of Senator Bradley, Wendy E. Lane and James McCann, as members of a CEO Search Committee, for their efforts in selecting a new CEO.

In addition, as part of their annual compensation, each non-employee director who is elected at the Company’s Annual General Meeting of Shareholders also receives time-based equity equivalent in value to $100,000 (based on the closing price of the Company’s shares as quoted on the NYSE on the date of grant) that vest in full on the one-year anniversary of the grant date. On May 7, 2012, the non-employee directors received 2,753 RSUs that will vest in full on May 7, 2013.

In 2013, the Board also approved an annual fee for the Non-Executive Chairman of the Board of $150,000 payable 50% in equity and 50% in cash, provided that the Non-Executive Chairman may elect to receive the fee 100% in stock.

Outside directors are subject to share ownership guidelines that require them to hold Company shares equal to the lesser of 3.5 times the directors’ cash retainer of $100,000 (i.e., $350,000) or 10,000 shares. Incumbent directors must comply by 2016 (i.e., five years of adoption of the guidelines). Ordinary shares, deferred shares, share equivalents, RSUs and restricted shares count toward satisfying the guidelines, but options to purchase shares do not. Each director is prohibited from transferring these shares until six months after he or she leaves Board service (other than to satisfy tax obligations on the vesting/distribution of existing equity awards), but is permitted to transfer any shares in excess of this amount. In the event an outside director has not acquired this threshold of shares, he or she is prohibited from transferring any Company shares (other than to satisfy tax obligations on the vesting/distribution of existing equity awards). In the case of financial hardship, the ownership guidelines would be waived until the hardship no longer applies or such appropriate time as the Compensation Committee determines. All directors currently satisfy the guidelines.

Sir Jeremy Hanley receives an additional annual fee of £50,000 for serving on the board of directors of Willis Limited, the Company’s principal insurance broking subsidiary outside of the USA. He has sat on the Willis Limited board of directors since March 12, 2008 and he also serves on the Willis Limited board of directors’ audit committee.

(4) The above fees reflect Sir Roy Gardner’s role as the Chairman of the Risk Committee.

(5) The above fees reflect Sir Jeremy Hanley’s role as a member of the Audit Committee. As noted above, he also receives an annual cash fee of £50,000 in connection with his service as a director on the Willis Limited board of directors.

(6) The above fees reflect Ms. Kravit’s role as a member of the Audit Committee.

(7) The above fees reflect Ms. Lane’s role as the Chairman of the Compensation Committee and a member of the Audit Committee. The fees also include the one-time special fee approved by the Board of $30,000 for her efforts in selecting a new Group CEO.

Plan Category	Number of Shares to be Issued Upon Exercise of Outstanding Options, Warrants and Rights			Weighted Average Exercise Price of Outstanding Options, Warrants and Rights (1)		Number of Shares Remaining Available for Future Issuance
Equity Compensation Plans Approved by Security Holders		18,761,121	(2)		32.76		11,228,595	(3)

Item 13 — Certain Relationships and Related Transactions, and Director Independence

Review and Approval of Related Person Transactions

Willis has adopted written policies and procedures governing the review and approval of transactions between the Company and any of its directors or executive officers, nominees for directors, any security holder who is known to the Company to own of record or beneficially more than 5% of any class of the Company’s voting securities or their immediate family members (each, a “Related Person”) to determine whether such persons have a direct or indirect material interest. The Company’s directors, nominees for directors and executive officers complete an annual director and officer questionnaire which requires the disclosure of related person transactions. In addition, directors, nominees for directors and executive officers are obligated to advise the Audit Committee of any related person transactions of which they are aware, or become aware, and, in the event that any such transactions involve difficult or complex issues, the directors and executive officers are obligated to advise the Group General Counsel. Further, transactions that are determined to be directly or indirectly material to a Related Person are disclosed in the Company’s Proxy Statement or Annual Report on Form 10 K in accordance with SEC rules. The Audit Committee reviews and approves or ratifies any related person transaction that is required to be disclosed. In the course of its review and approval or ratification of a disclosable related person transaction, the Audit Committee considers, among other factors it deems appropriate:

• The position within or relationship of the Related Person with the Company;

• The materiality of the transaction to the Related Person and the Company, including the dollar value of the transaction, without regard to profit or loss;

• The business purpose for and reasonableness of the transaction (including the anticipated profit or loss from the transaction), taken in the context of the alternatives available to the Company for attaining the purposes of the transaction;

• Whether the transaction is comparable to a transaction that could be available on an arms-length basis or is on terms that the Company offers generally to persons who are not Related Persons;

• Whether the transaction is in the ordinary course of the Company’s business and was proposed and considered in the ordinary course of business; and

• The effect of the transaction on the Company’s business and operations, including on the Company’s internal control over financial reporting and system of disclosure controls or procedures, and any additional conditions or controls (including reporting and review requirements) that should be applied to such transaction.

Any member of the Audit Committee who is a Related Person with respect to a transaction under review may not participate in the deliberations or vote regarding the approval or ratification of the transaction, provided, however, that such director may be counted in determining the presence of a quorum at a meeting at which the Audit Committee considers the transaction.

2012 Related Person Transactions Under Item 404 of Regulation S-K

David Hearn is the brother of Peter Hearn, the Chairman of Willis Re and a 2012 executive officer, and is employed by a Willis subsidiary. David Hearn’s 2012 total compensation (including salary, bonus and long-term incentive awards) was $1,225,000. Both David Hearn and Peter Hearn are unrelated to Stephen Hearn, the Group Deputy CEO, CEO and Chairman of Willis Global. No other transactions are required to be disclosed under Item 404 of Regulation S-K.

Board and Committee Member Independence

Based on the recommendation of the Governance Committee, the Board has determined that, with the exception of Mr. Casserley and Mr. Plumeri (who will retire as Chairman and a member of the Board on July 7, 2013), (i) all the directors and director nominees shown above and (ii) the current members of the Audit Committee, Compensation Committee, Governance Committee and the Risk Committee are independent under the relevant SEC rules, NYSE listing standards and the Board’s Director Independence Standards. The Board’s Director Independence Standards are part of the Company’s Corporate Governance Guidelines adopted by the Board and which comply and meet the requirements of the NYSE’s listing standards.

As discussed above, each director nominee has significant experience and affiliations with other organizations. Accordingly, in evaluating the independence of each director, the Governance Committee considered that in the ordinary course of business, the Company provides services (such as insurance broking or consultancy services) to, receives services from or provides charitable donations to organizations affiliated with the directors. This includes a $150,000 charitable contribution made by the Company to CASA, a charitable organization that employs Messrs. Califano and Lane and whose board includes Messrs. Lane, Califano, and Plumeri. In addition, in the ordinary course of business and on an arm’s length basis, Jeffrey Lane, Robyn Kravit and James McCann receive broking or consultancy services from the Company on a personal basis. However, the Governance Committee determined that, in all of the above cases, the transactions do not impair the relevant director’s independence under the applicable SEC rules, NYSE listing standards or the Company’s Governance Guidelines.

The Audit Committee approved all of the services described above in accordance with the Company’s pre-approval policy.

Audit Committee Pre-Approval Process

The Audit Committee has adopted a policy regarding the pre-approval of services provided by the Company’s independent auditors, which can be found in the Investor Relations — Corporate Governance section of the Company’s website at www.willis.com. This policy requires all services provided by the Company’s independent auditors, both audit and permitted non-audit services, to be pre-approved by the Audit Committee or the Chairman of the Audit Committee or, in his absence, any other member of the Committee. The pre-approval of audit and permitted non-audit services may be given at any time before the commencement of the specified service.

(i) Diluted earnings per share are calculated by dividing net income by the average number of shares outstanding during each period. However, potentially issuable shares were not included in the calculation of diluted earnings per share for the three months and twelve months ended December 31, 2012 because the Company’s net loss rendered their impact anti-dilutive. The dilutive impact of potentially issuable shares is included on reconciling to adjusted earnings per share from continuing operations.
