GENERAL INFORMATION REGARDING THE 2018

ANNUAL MEETING OF STOCKHOLDERS

Meeting Date and Location

The 2018 Annual Meeting of Stockholders (the “Annual Meeting”) of Lennox International Inc. (also referred to in this Proxy Statement as the “Company,” “us,” “we,” or “our”) will be held on Wednesday, May 16, 2018 at 10:30 a.m., local time, at the Company’s Corporate Headquarters, 2140 Lake Park Blvd., Richardson, Texas 75080. We began mailing or making available this Proxy Statement and the accompanying Notice of Annual Meeting of Stockholders, Proxy Card and Annual Report to Stockholders, which includes our Annual Report on Form 10-K, to our stockholders on or about April 4, 2018 for the purpose of soliciting proxies on behalf of our Board of Directors (the “Board”).

Matters to be Voted On

At the meeting, you will be asked to vote on three proposals. Our Board recommends you vote “for” each of the director nominees in Proposal 1and “for” Proposals 2 and 3. The proposals to be voted on at the Annual Meeting are:

• Proposal 1: To elect three Class II directors to hold office for a three-year term expiring at the 2021 Annual Meeting of Stockholders;

• Proposal 2: To ratify the appointment of KPMG LLP as our independent registered public accounting firm for the 2018 fiscal year; and

• Proposal 3: To conduct an advisory vote to approve the compensation of our named executive officers (“NEOs”) as disclosed in this Proxy Statement.

Record Versus Beneficial Ownership of Shares

If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are the "stockholder of record" with respect to those shares. If you are a stockholder of record, we sent our proxy materials directly to you.

If your shares are held in a stock brokerage account or by a bank, you are considered the “beneficial owner” of shares held in street name. In that case, our proxy materials have been forwarded to you by your broker or bank, which is considered the stockholder of record with respect to those shares. Your broker or bank will also send you instructions on how to vote. If you have not heard from your broker or bank, please contact them as soon as possible.

Record Date and Number of Votes

You are entitled to vote at the Annual Meeting if you were a stockholder of record at the close of business on March 20, 2018, our Annual Meeting record date. At the close of business on the record date, there were 41,318,011 shares of our common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote.

Quorum Requirement

A quorum is required to transact business at the Annual Meeting. To achieve a quorum at the Annual Meeting, stockholders holding a majority of our outstanding shares of common stock entitled to vote must be present either in person or represented by proxy. Shares held by us in treasury will not count towards the calculation of a quorum.

If a quorum is not present at the Annual Meeting, we expect the Annual Meeting will be adjourned or postponed to solicit additional proxies. In such event, the Chairman or stockholders representing a majority of the outstanding shares entitled to vote at the Annual Meeting and present in person or by proxy at the meeting may adjourn the Annual Meeting.

1

Abstentions and Broker Non-Votes

If a broker or bank holds shares in “street name” (that is, in the name of a bank, broker, nominee or other holder of record) and the beneficial owner does not provide the broker or bank with specific voting instructions, the broker or bank only has discretion to vote on routine matters (referred to as “broker non-votes”) but does not have discretion to vote on non-routine matters.

Pursuant to New York Stock Exchange (“NYSE”) rules, Proposal 1 (election of directors), and Proposal 3 (advisory vote on the compensation of our NEOs) are non-routine matters for which your broker or bank may not exercise voting discretion if it does not receive voting instructions from you. Proposal 2 (ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the 2018 fiscal year) is a routine matter for which your broker or bank may exercise voting discretion even if it does not receive voting instructions from you. As a result, if you are a beneficial owner of shares held in street name, it is critical that you cast your vote in order for it to be counted on Proposals 1 and 3.

Broker non-votes will not be counted as votes “for” or “withheld” for Proposal 1 or “for” or “against” Proposal 3. Abstentions will be counted as votes “against” Proposals 2 and 3 but will not be counted as votes “for” or “withheld” for Proposal 1.

Vote Requirement for each Proposal

If a quorum is present, our Bylaws require, for purposes of Proposal 1, that a director nominee receive a majority of the votes cast with respect to his or her election in an uncontested election (that is, the number of shares voted “for” a director nominee must exceed the number of “withheld” votes cast for that nominee) to be elected. Each of our director nominees is currently serving on the Board. If a nominee who is currently serving as a director is not re-elected, Delaware law provides that the director would continue to serve on the Board as a “holdover director.” Under our Bylaws and Corporate Governance Guidelines, each director submits an advance, contingent resignation that the Board may accept if stockholders do not re-elect the director. In that situation, our Board Governance Committee would make a recommendation to the Board about whether to accept or reject the resignation, or whether to take other action. The Board would act on the Board Governance Committee’s recommendation, and publicly disclose its decision and the rationale behind it within 90 days from the date that the election results were certified.

If a quorum is present, Proposal 2 (ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the 2018 fiscal year), and Proposal 3 (advisory vote on the compensation of our NEOs) will require the affirmative vote of a majority of the shares of common stock present in person or represented by proxy at the meeting and entitled to vote thereon.

Voting Procedures

Registered holders may vote in person at the Annual Meeting, by the Internet, by telephone, or, if they received a printed copy of these proxy materials, by mail. If your shares are held in street name, you will receive instructions from a bank, broker, nominee or other holder of record that you must follow in order for your shares to be voted. If you have not received voting instructions from your bank, broker, or other holder of record, please contact them as soon as possible.

A representative of Mediant Communication will tabulate the votes and act as inspector of election at the Annual Meeting.

2

Changing Your Vote

You can revoke or change your vote on a proposal at any time before the Annual Meeting for any reason by revoking your proxy. For stockholders of record, proxies may be revoked by delivering a written notice of revocation, bearing a later date than your proxy, to our Corporate Secretary at or before the Annual Meeting. Proxies may also be revoked by:

• submitting a new written proxy bearing a later date than a proxy you previously submitted prior to or at the Annual Meeting;

• voting again by Internet or telephone before 11:59 p.m., Eastern Time, on May 15, 2018; or

• attending the Annual Meeting and voting in person.

In each case, the later submitted vote will be recorded and the earlier vote revoked. Any written notice of a revocation of a proxy should be sent to Lennox International Inc., 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Corporate Secretary. To be effective, the revocation must be received by our Corporate Secretary before the taking of the vote at the Annual Meeting.

If your shares are held in street name, you must follow the specific voting directions provided to you by your bank, broker, nominee or other holder of record to change or revoke any instructions you have already provided. Alternatively, you may obtain a proxy from your bank, broker or other holder of record and provide it with your vote at the Annual Meeting.

Other Business; Adjournments

We are not aware of any other business to be acted upon at the Annual Meeting. However, if you have voted by proxy and other matters are properly presented at the Annual Meeting for consideration in accordance with our Bylaws, the persons named in the accompanying Proxy Card will have discretion to act on those matters according to their best judgment or the Board’s recommendation. In the absence of a quorum, the Chairman or stockholders representing a majority of the votes present in person or by proxy at the meeting may adjourn the meeting.

Upon the recommendation of the Board Governance Committee, the Board has nominated three Class II directors for re-election to our Board to hold office for a three-year term expiring at the 2021 Annual Meeting of Stockholders. All Class I and III directors will continue in office until the expiration of their terms at the 2020 and 2019 Annual Meeting of Stockholders, respectively.

For each director and director nominee, the information presented includes the positions held, principal occupation, and business experience as of March 20, 2018. The biographical description below for each director and director nominee also includes the specific experience, qualifications, attributes and skills that led to the Board’s conclusion that such person should serve as a director of the Company at this time, in light of our business and structure.

If you do not wish to vote your shares for any particular nominee, you may withhold your vote for that particular nominee. If any Class II director nominee becomes unavailable to serve, the persons named in the accompanying Proxy Card may vote for any alternate designated by the incumbent Board, or the number of directors constituting the Board may be reduced.

Audit Committee Approval of Audit and Non-Audit Services

The Audit Committee pre-approves all audit services provided by our independent registered public accountants. In addition, all non-audit services provided by KPMG LLP are pre-approved in accordance with our policy that prohibits our independent registered public accountants from providing services specifically prohibited by the Securities and Exchange Commission (“SEC”). For permissible non-audit services, the Audit Committee has delegated pre-approval authority to the Audit Committee Chairman. In addition, the Audit Committee has approved annual maximum amounts for tax advisory and tax return services. No engagements are commenced until the Audit Committee Chairman’s approval has been received. All approved services are reported to the full Audit Committee at each quarterly meeting. In accordance with the foregoing, all services provided by KPMG LLP in 2016 and 2017 were pre-approved by the Audit Committee.

AUDIT COMMITTEE REPORT

The Audit Committee maintains effective working relationships with the Board, management, the Company’s internal auditors and KPMG LLP, the Company’s independent registered public accounting firm (the “Independent Accountants”). As set forth in the Audit Committee Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that our Company’s consolidated financial statements and disclosures are complete and accurate and in accordance with U.S. generally accepted accounting principles and applicable rules and regulations. The Independent Accountants are responsible for auditing the Company’s consolidated financial statements and expressing an opinion as to the conformity of these financial statements with U.S. generally accepted accounting principles and on the Company’s internal control over financial reporting.

The Audit Committee has (1) reviewed and discussed the Company’s audited consolidated financial statements for the year ended December 31, 2017 with the Company’s management and with the Independent Accountants; (2) discussed with the Independent Accountants the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board; and (3) received the written disclosures and the letter from the Independent Accountants required by applicable requirements of the Public Company Accounting Oversight Board regarding the Independent Accountants’ communications with the Audit Committee concerning independence, and the Audit Committee has discussed with the Independent Accountants the Independent Accountants’ independence and considered whether the provision of non-audit services by the Independent Accountants to the Company is compatible with the Independent Accountants’ independence.

Members of the Audit Committee rely, without independent verification, on the information provided and on the representations made by management and the Independent Accountants. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not assure that the audits of the Company’s consolidated financial statements have been carried out in accordance with generally accepted auditing standards, that the consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles or that the Company’s Independent Accountants are in fact “independent.”

Based upon the reviews and discussions described above, and subject to the limitations on the role and responsibilities of the Audit Committee referred to in this report and in the Audit Committee Charter, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

CORPORATE GOVERNANCE

Director Independence

Our Corporate Governance Guidelines require that a majority of our directors be “independent,” and that the Compensation & Human Resources, Board Governance and Audit Committees consist exclusively of independent directors as defined under the NYSE listing standards, the Securities Exchange Act of 1934 (the "Exchange Act") and any other applicable laws or regulations regarding independence. No director qualifies as “independent” unless the Board affirmatively determines that the director has no material relationship with the Company.

Applying these standards, the Board has determined that all of our Board members are independent, except Todd Bluedorn, our Chairman of the Board and Chief Executive Officer (“CEO”), and that all of the members of the Board’s standing committees consist exclusively of independent directors (see table under “Board Committees”).

In making its determination as to the independence of our directors, the Board Governance Committee and the Board considered that Ms. Quintos serves as Chief Customer Officer of Dell, Inc., which provides computer equipment and related items to the Company in the ordinary course of business.

Board Meetings and Leadership Structure

Mr. Bluedorn serves as the Chairman of the Board and Chief Executive Officer (“CEO”). The Board has determined that Mr. Bluedorn’s position as Chairman allows him to be a liaison between management and the Board of Directors, providing the Board with the benefit of management’s perspective on our business strategy and all other aspects of the business as the Board performs its oversight role.

Our Corporate Governance Guidelines provide for a Lead Director position, and the Board elected Todd J. Teske as Lead Director in 2015. The Board believes the Lead Director position provides helpful guidance to the independent directors in their oversight of management. The Lead Director, among other things, presides at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors, serves as liaison between the Chairman and the independent directors, assists the Chairman in planning agendas for Board meetings and advises on the quality of the information provided to the Board. The Lead Director also has the authority to call meetings of the independent directors, and, if requested by major stockholders, is available for consultation and direct communication.

The Board met six times in 2017. All directors attended more than 75% of the total number of meetings of the Board and committees of the Board on which they served. Our Corporate Governance Guidelines include a policy that Board members are expected to attend the annual meeting of stockholders. All of the individuals serving as directors at the time of our 2017 Annual Meeting of Stockholders attended our 2017 Annual Meeting of Stockholders.

Risk Oversight and Compensation Risk Analysis

The Board oversees the Company’s processes to manage risk at the Board and senior management levels. The Audit Committee oversees the guidelines and policies that govern the Company’s processes to assess and manage significant enterprise risk exposure. While the Board and Audit Committee oversee the Company’s risk management, our management is responsible for the development, implementation, and maintenance of our risk management processes. Management provides periodic reports to the Board and Board committees, as appropriate, on its assessment of strategic, operational, legal and compliance, and financial reporting risks to the Company. The Board and Board committees, as appropriate, review and consider the management reports provided on the Company’s enterprise risk and risk management strategy.

The Board has reviewed the Company’s compensation policies and practices to determine if risks arising from those policies and practices are reasonably likely to have a material adverse effect on the Company. Based on this review, the Board has not identified any risks arising from the compensation policies and practices that are reasonably likely to have a material adverse effect on the Company. The Company incorporates short-term and long-term incentive programs for cash and equity awards that are designed to reward successful execution of its business strategy and achievement of desired business results. Additionally, the Company has stock ownership

12

requirements and clawback provisions to align the interests of its executive officers with the interests of its stockholders. For non-executive employees, the Company uses a variety of incentive compensation programs to motivate its employees to attain individual goals and support the financial performance of the Company. All of the Company’s material incentive compensation plans are reviewed at least annually by senior management.

Board Committees

The standing committees of the Board are as follows: Audit, Board Governance, Compensation and Human Resources, and Public Policy. The Board has adopted charters for each of these committees, copies of which are available on our website at www.lennoxinternational.com by following the links “About Us — Corporate Governance — Committee Charters.” Each of these Board committees is led by a different independent director and all members of our Board committees are independent directors.

The following table provides current membership information for each of the Board committees and indicates which directors our Board determined are independent, as defined by the NYSE.

Audit Committee

The Audit Committee assists the Board in fulfilling its oversight responsibilities relating to the integrity of our financial statements and related systems of internal controls, our compliance with legal and regulatory requirements, the independent registered public accounting firm’s qualifications, independence and performance and the performance of our internal audit function. The Audit Committee also has the direct responsibility for the appointment, compensation, retention and oversight of our Independent Accountants.

The Board has determined that each Audit Committee member is independent, as independence is defined for audit committee members by the SEC and the NYSE. The Board has also determined that each Audit Committee member is “financially literate” as defined by the NYSE, has accounting or related financial management expertise and is an audit committee financial expert as defined by the SEC. The Audit Committee met nine times in 2017.

Board Governance Committee

The Board Governance Committee assists the Board by identifying individuals qualified to become Board members, developing qualification criteria for Board membership, making recommendations to the Board regarding the appropriate size of the Board and appointment of members to the Board’s committees, developing and recommending to the Board any changes to the Corporate Governance Guidelines and Code of Business Conduct applicable to our Company, developing our Company’s director education programs, and overseeing the evaluation of our Board. The Board Governance Committee also conducts an individual peer review for any directors who are scheduled to be re-nominated. The Board has determined that each member of the Board Governance Committee is independent as independence is defined by the NYSE. The Board Governance Committee met twice in 2017.

13

Compensation and Human Resources Committee

The Compensation and Human Resources Committee determines the compensation philosophy and oversees the compensation programs for the Company’s executive officers and the non-employee members of the Board. This Committee’s responsibilities include oversight of the short- and long-term incentive plans and the senior management succession plans. The Committee also reviews the funding requirements and investment policies for the defined benefit and defined contribution retirement plans, and the performance of investment funds, investment advisors and investment managers under those plans. The Compensation Committee may delegate its responsibilities to a subcommittee comprised of Compensation Committee members.

Although the Committee seeks input from the CEO on various elements of executive compensation, the Committee determines and approves the final compensation elements and amounts to be provided to the Company’s NEOs. The independent members of the Board (rather than the Committee) have direct responsibility for approving CEO and Board compensation; however, the Committee reviews and recommends proposed changes to CEO and Board compensation to the independent members of the Board for approval. See “Executive Compensation — Compensation Discussion and Analysis” for information concerning the committee’s philosophy and objectives in overseeing executive compensation. The Board has affirmatively determined that each member of the Committee is independent as defined for compensation committee members by the NYSE. The Board has also determined that each member of the Committee is a “non-employee director” for purposes of Section 16b-3 of the Exchange Act and, along with each of the independent directors, is an “outside director” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). The Committee met five times in 2017.

The Committee’s charter authorizes the Committee to retain third-party compensation consultants and to obtain advice and assistance from internal or external legal, accounting or other advisors. The Committee retains Frederic W. Cook & Co., Inc. (“FW Cook”) as its executive compensation consultant to provide objective analysis, advice and recommendations regarding the compensation of our executives and non-employee directors. FW Cook does not provide any other services to the Company. See “Executive Compensation — Compensation Discussion and Analysis” for further information regarding our executive compensation programs and the scope of services provided by FW Cook. The Committee has concluded that FW Cook’s work does not raise any conflicts of interest that require disclosure under applicable SEC regulations.

Public Policy Committee

The Public Policy Committee is responsible for overseeing our Company’s environmental, health and safety issues, and our position on corporate social responsibility and significant public issues that affect our stockholders. The Board has determined that each Public Policy Committee member is independent as defined by the NYSE. The Public Policy Committee met twice in 2017.

Director Nomination Process and Nominee Criteria

The Board is responsible for nominating candidates for Board membership. The Board has delegated the director screening and recruitment process to the Board Governance Committee. In this capacity, the Board Governance Committee develops and periodically reviews the qualification criteria for Board membership, identifies new director candidates, and makes recommendations to the Board regarding the appropriate size of the Board and appointment of members to the Board’s committees. The Board Governance Committee typically retains a third-party search firm to assist in identifying and evaluating potential new director candidates. Qualifications required of individuals for consideration for Board membership will vary according to the particular areas of expertise, experience and skills being sought as a complement to the existing Board composition at the time of any vacancy.

Neither the Board nor the Board Governance Committee has a formal diversity policy. However, our Corporate Governance Guidelines provide that, when nominating new members to the Board, the Board will seek the best qualified candidates with consideration for diversity. This consideration may include diversity of experience, functional expertise and industry knowledge. Our Board of Director Qualification Guidelines further provide that the Board Governance Committee consider a candidate’s diversity of viewpoints in determining the particular qualifications desired for any new Board member.

14

According to our Board of Director Qualification Guidelines, the Board Governance Committee considers the following factors in evaluating candidates, in addition to other factors that the Board Governance Committee deems relevant:

• Personal Characteristics: leadership, integrity, interpersonal skills and effectiveness, accountability, and high performance standards;

• Business Attributes: high levels of leadership experience in business, substantial knowledge of issues faced by publicly-traded companies, experience in positions demonstrating expertise, including on other boards of directors, financial acumen, industry and Company knowledge, diversity of viewpoints, and experience in international markets and strategic planning;

• Independence: independence based on the standards established by the NYSE, the SEC, and any other applicable laws or regulations;

• Professional Responsibilities: willingness to commit the time required to fully discharge his or her responsibilities, commitment to attend meetings, ability and willingness to represent the stockholders’ long- and short-term interests, awareness of our responsibilities to our customers, employees, suppliers, regulatory bodies and the communities in which we operate and willingness to advance his or her opinions while supporting the majority Board decision, assuming questions of ethics or propriety are not involved;

• Governance Responsibility: ability to understand, and distinguish between, the roles of governance and management; and

• Availability and Commitment: availability based on the number of commitments to other entities existing or contemplated by the candidate.

The full text of our Board of Directors Qualification Guidelines can be found on our website at http://www.lennoxinternational.com by following the links “About Us — Corporate Governance — Board of Director Qualification Guidelines.”

When a vacancy occurs on the Board, a majority of the directors then in office may fill the vacancy, or the vacancy may remain open or the size of the Board may be reduced. The Board Governance Committee evaluates nominees to the Board to fill any vacancy on the Board.

Stockholder Nominations for Director

The Board Governance Committee considers nominees for election to the Board recommended by stockholders in the same manner as other candidates. A stockholder wishing to nominate a candidate for election to the Board at a meeting of the stockholders (“Nominating Stockholder”) is required to give written notice to our Corporate Secretary of his or her intention to make a nomination in accordance with the terms of our Bylaws. The Nominating Stockholder must be a holder of record of stock of the Company entitled to vote at the annual meeting of stockholders and must appear at the annual meeting of stockholders to nominate such person. The Nominating Stockholder must include a written consent from its proposed director nominee. The proposed director nominee must also represent and agree that he or she (1) has not and will not give any assurance or commitment not disclosed to the Company on how he or she would vote on any issue or question, (2) has not and will not become party to any agreement not disclosed to the Company regarding direct or indirect compensation (other than from the Company) for his or her service as a director, and (3) if elected, will comply with all applicable policies and guidelines of the Company. We must receive the notice of nomination at least 60 days but no more than 90 days prior to the annual meeting of stockholders. However, if we give less than 70 days’ notice of the date of the annual meeting of stockholders, the notice of nomination must be received within 10 days following the date on which notice of the date of the annual meeting of stockholders was mailed or such public disclosure was made to our stockholders.

15

Pursuant to our Bylaws, the notice for the proposed director nominee must contain certain information about the nominee, the Nominating Stockholder and any person “acting in concert” with the Nominating Stockholder, including descriptions of any arrangements or understanding related to the nomination, the information that would be required if such person was making a stockholder proposal (as described under “Stockholder Proposals for the 2019 Annual Meeting of Stockholders — Proposals Not for Inclusion in the Proxy Statement to be Offered at the 2019 Annual Meeting”) and other information sufficient to allow the Board Governance Committee to determine if the candidate meets our qualification criteria for Board membership. The Board Governance Committee may require the proposed director nominee to furnish additional information in order to determine that person’s eligibility to serve as a director. A nomination that does not comply with the above procedure will be disregarded. Nominating Stockholders whose nominations comply with the foregoing procedure and who meet the criteria described above under the heading “Director Nomination Process and Nominee Criteria,” and in our Corporate Governance Guidelines, will be evaluated by the Board Governance Committee in the same manner as the Board Governance Committee’s nominees.

Stockholder Communications with Directors

Stockholders may send written communications to the Board by email to directors@lennoxintl.com, or by regular mail to 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Board of Directors, c/o Corporate Secretary.

Stockholder communications received by the Corporate Secretary will be delivered to one or more members of the Board or management, as determined by the Corporate Secretary. Any allegations of accounting, internal controls or auditing-related complaints or concerns will be directed to the Chairman of the Audit Committee.

Interested parties may communicate with non-management directors of the Board by sending written communications to the address listed above to the attention of the Lead Director.

Other Corporate Governance Policies and Practices

Code of Business Conduct

The Company has adopted a Code of Business Conduct that applies to all its directors and employees, including its senior financial and principal executive officers. The Code of Business Conduct covers a variety of matters, such as acting with integrity and compliance with laws, including anti-corruption laws. Amendments to and waivers, if any, of the Code of Business Conduct as it pertains to the executive officers will be disclosed on our website. The Code of Business Conduct is available on the Company’s website at www.lennoxinternational.com by following the links “About Us — Our Core Values — Code of Conduct.”

Corporate Governance Guidelines

The Company has adopted Corporate Governance Guidelines that are available on the Company’s website at www.lennoxinternational.com by following the links “About Us — Corporate Governance — Corporate Governance Guidelines.”

Executive Session Meetings

In accordance with our Corporate Governance Guidelines, the non-management directors of our Board, all of whom are independent, meet regularly in executive session without the presence of management. The Lead Director chairs the executive session meetings of our independent directors.

Whistleblower Procedures

The Audit Committee has established procedures for the handling of complaints regarding accounting, internal accounting controls, or auditing matters, including procedures for confidential and anonymous submission by our employees of concerns regarding such matters. The Company’s Code of Business Conduct prohibits retaliation against employees who report violations or suspected violations of the Code of Business Conduct.

PROPOSAL 3

ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

In accordance with Section 14A of the Exchange Act, we are asking our stockholders to vote to approve the compensation of our Company’s NEOs (the “Say-on-Pay vote”), as disclosed in this Proxy Statement. The Say-on-Pay vote is an advisory vote on the resolution below and is not binding on the Company or the Board. Although the vote is non-binding, the directors value the opinions of the stockholders and will consider the outcome of the vote when making future compensation decisions. Our next advisory vote on the frequency of shareholder votes on executive compensation will take place at our annual meeting of shareholders in 2023.

As described more fully in the “Compensation Discussion and Analysis” section of this Proxy Statement, the Company designed its market competitive NEO compensation program to reward successful execution of its business strategy and achievement of desired business results, with a focus on creating alignment with the interests of our stockholders. The program seeks to achieve these goals on an annual and long-term basis through an appropriate combination of base pay, annual incentives and long-term incentives.

For our NEOs, the majority of compensation is both stock-based and contingent on performance. The annual incentive payout is based on Company financial performance metrics of core net income and free cash flow, and for NEOs that are business segment leaders, a combination of Company and business segment performance. Our long-term incentives currently include: (1) performance shares units, which are designed to link compensation to the Company’s three-year financial performance as measured by return on invested capital and core net income growth; (2) stock appreciation rights, which are designed to incentivize NEOs to grow our business and deliver increased returns to our stockholders and (3) restricted stock units, which are designed to support our retention efforts.

The Company also has several governance policies in place to align executive compensation with stockholder interests and mitigate risk. These policies include: stock ownership guidelines, a prohibition on hedging and pledging of Company stock, a clawback policy and post-employment non-competition and non-solicitation restrictions. These policies are discussed in detail in the “Compensation Discussion and Analysis” section of this Proxy Statement.

In 2017, the Company continued to drive business performance, and create stockholder value through its focus on innovation, productivity and efficient use of cash. Highlights of our 2017 performance include the following:

• Net sales up 5% from 2016 to approximately $3.8 billion;

• Record total segment profit margin of 13.4%, up 50 basis points from 2016;

• One-year total stockholder return of 37%, three-year total stockholder return of 127% and five-year total stockholder return of 320%; and

• Increased dividend 19%, which resulted in approximately $80 million cash paid to stockholders and used an additional $250 million for stock repurchase programs.

Financial results, including those from prior periods, are described in more detail in our Form 10-K for the fiscal year ending December 31, 2017. For further detail and a comparison of Segment Profit to Operating Income, see Note 18 in the Notes to the Consolidated Financial Statements in our Form 10-K for the fiscal year ended December 31, 2017. All total stockholder return calculations assume reinvestment of dividends.

We are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the compensation of the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and narrative discussion is hereby APPROVED.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE

COMPENSATION OF THE NEOS AS DISCLOSED IN THIS PROXY STATEMENT.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Executive Summary

The Company’s executive compensation program is designed to attract, retain and motivate leadership talent, align executive compensation with short- and long-term business goals, maintain market competitiveness and drive increased stockholder value by maintaining a strong alignment between pay and performance. Highlights of our 2017 financial performance and a description of the linkage between executive compensation and financial performance are set forth below.

Financial Highlights

In 2017, the Company continued to drive business performance and create stockholder value through its focus on innovation, productivity and efficient use of cash. Highlights of our 2017 performance include the following:

• One-year total stockholder return of 37%, three-year total stockholder return of 127% and five-year total stockholder return of 320%; and

• Increased dividend 19%, which resulted in approximately $80 million cash paid to stockholders and paid out an additional $250 million for stock repurchase programs.

Financial results, including those from prior periods, are described in more detail in our Form 10-K for the fiscal year ending December 31, 2017. For further detail and a comparison of Segment Profit to Operating Income, see Note 18 in the Notes to the Consolidated Financial Statements in our Form 10-K for the fiscal year ended December 31, 2017. All total stockholder return calculations assume reinvestment of dividends.

Pay-for-Performance Linkage

Pay-for-performance is the philosophical foundation for our annual short-term and long-term incentive programs. Highlights of our incentive compensation programs and how they are linked to our pay-for-performance philosophy include:

• 85% of our CEO’s target compensation is variable — tied to annual short-term and long-term incentives;

• 70% of our NEOs’ long-term incentive compensation is performance-based, with the remainder provided as restricted stock units for retention purposes;

• CEO compensation in 2017 (as shown in the Summary Compensation Table) increased 14%, while our one-year total stockholder return increased 37%; and

• Payouts under our performance share unit program averaged 186% of target over the last three completed performance cycles (each spanning three years and overlapping with each other), while total stockholder return over that same five-year period was 320%.

18

Overview

This Compensation Discussion and Analysis (“CD&A”) describes the philosophy and objectives of the compensation program for our NEOs. The Compensation and Human Resources Committee of the Board (the “Committee”) establishes and administers our executive compensation program, practices and policies. The Committee receives input from management and its executive compensation consultant, and considers competitive practices, our business objectives, stockholder interests, regulatory requirements and other relevant factors to develop our executive compensation program in an effort to most effectively drive the achievement of the Company’s business objectives.

Stockholder Input

The Committee considers input from stockholders, including the result of the annual Say-on-Pay vote, in determining compensation policies and decisions. At our 2017 Annual Meeting, the advisory vote on the compensation of the Company's NEOs received the approval of over 99% of the stockholders voting for and against this item. In an effort to maintain this strong support from stockholders, management has continued to review proxy advisor and investor concerns regarding executive compensation and governance and has selectively communicated with stockholders. The Say-on-Pay vote result was one of many factors the Committee considered in deciding to not implement any major changes to the executive compensation program in 2017.

Positive Governance Practices

The Committee assesses trends and developments in executive compensation practices and implements those that best fit with the Company’s business strategy and our stockholders’ long-term interests. Below are some of the practices we have incorporated into our compensation program, as described elsewhere in this Proxy Statement:

	What We Do		What We Don't Do
þ	Median compensation philosophy	ý	No significant perquisites
þ	Long-term balance in compensation structure	ý	No tax gross-ups on any CIC agreements after 2009
þ	Use of independent compensation consultant	ý	No hedging of Company stock
þ	Annual risk assessment	ý	No pledging of Company stock
þ	Rigorous stock ownership guidelines	ý	No dividends on equity awards in annual grant
þ	Clawback provisions	ý	No repricing of stock appreciation rights or options
þ	Non-Competition / Non-Solicitation restrictions	ý	No cash buyouts of underwater stock appreciation rights or options
þ	Annual reviews of share utilization
þ	Regular market assessment of our peer group

Executive Compensation Philosophy and Key Objectives

Pay-for-Performance

We maintain a pay-for-performance philosophy designed to reward successful execution of our business strategy and achievement of desired business results, with a focus on aligning compensation with the interests of our stockholders. When our financial results exceed performance goals, monetary rewards to our NEOs generally pay out at higher levels. When our financial results fall below performance goals, monetary awards to our NEOs generally pay out at lower levels and may not pay out at all.

Recent payouts under our short-term incentive program and our long-term incentive program demonstrate the strong link between Company performance and actual payments made to our NEOs. In 2017, overall Company performance exceeded goals and, as a result, our NEOs received slightly above target levels of payouts under our annual short-term incentive compensation program. Over the last three years, our financial performance resulted in record weighted average return on invested capital of 30.8% and a compound annual growth rate of Company core net income of 16.6%. As a result, our NEOs received an above target performance share unit payout under our long-term incentive plan, consistent with our pay-for-performance approach and results-oriented compensation.

The graph below illustrates the directional alignment of pay and performance by showing changes in CEO annual compensation (using totals from the Summary Compensation Table) versus changes in total stockholder return (“TSR”) over the last several years. The shaded bars represent the Change in Pension Value, which is impacted by interest rate changes, while the solid bars represent all other Summary Compensation Table pay.

$ amounts are in thousands. TSR represents the change in a $100 investment from the end of year 2012 assuming reinvestment of dividends.

Key Strategic Objectives

The strategic objectives of our executive compensation program are to:

• attract, retain and motivate top executive talent;

• align compensation with the achievement of short-term and long-term business goals;

• maintain a market-competitive executive compensation program; and

• drive increased stockholder value by maintaining a strong alignment between pay and performance.

Process for Determining Named Executive Officer Compensation

Market Competitive Compensation

To maintain a market-competitive program, the Committee uses benchmarking data when establishing executive compensation. Benchmarking against a representative peer group assists the Committee in assessing the competitiveness of our executive compensation program.

Our Company’s compensation peer group, as reviewed and approved by the Committee, included the following 15 companies (the “Compensation Peer Group”):

•    A. O. Smith Corporation	•    Fortune Brands Home & Security, Inc.	•    Regal Beloit Corporation
•    Acuity Brands, Inc.	•    Hubbell Inc.	•    Rockwell Automation, Inc.
•    Crane Company	•    Kennametal Inc.	•    Snap-On Incorporated
•    Dover Corporation	•    Owens Corning	•    The Timken Company
•    Flowserve Corporation	•    Pentair, Inc.	•    USG Corporation

The Committee selected the Compensation Peer Group using the following criteria:

• industry — building products, electrical components/equipment and industrial machinery;

• revenues of approximately 0.5 to 2.0 times our revenues;

• business and product mix similar to ours; and

• international presence and operations.

In 2017, the Committee analyzed the Compensation Peer Group on the criteria above and adjusted the group by replacing Briggs & Stratton and Armstrong World Industries with Dover Corporation and Hubbell. These changes were made as a result of lower revenues at Briggs & Stratton and Armstrong World Industries and to move Lennox closer to the peer group median, while maintaining a close relationship to other peer criteria.

In addition to comparing our NEO compensation to the compensation provided by our Compensation Peer Group, the Committee also referenced published compensation data and other studies of compensation trends and practices (all such data and practices, including our Compensation Peer Group, is collectively referred to as the “Market”).

21

Pay Positioning and Compensation Mix

For 2017, the Committee targeted all elements of compensation for the Company’s NEOs at the 50th percentile of the Market and granted a majority of total compensation to our NEOs in the form of incentive compensation. The 2017 target compensation mix for the CEO and the average target compensation mix for the other NEOs are shown in the graphs below.

CEO - Target Compensation Mix	Other NEOs - Target Compensation Mix

The CEO’s target compensation mix, consistent with Market practice, has more “at-risk” performance-based incentive compensation than the other NEOs due to his broad influence on Company performance.

Compensation Analysis

Beyond traditional market analysis, the Committee utilizes various other compensation analyses to assist with its decision making process. Below are examples of information the Committee reviews and considers, as appropriate, when making compensation decisions:

• “all in” compensation summaries and pay histories for the CEO and executive officers

• CEO realized pay analysis

• CEO pay vs. performance analysis

• dilution and share utilization analysis, projections and benchmarking

• equity compensation expense analysis

• short-term and long-term incentive design, metric and vehicle prevalence

• short-term and long-term incentive plan performance results

Role of Management

The Committee obtains input from management and the Committee’s consultant when making NEO compensation decisions. The CEO makes recommendations to the Committee with respect to all of the elements of compensation for each NEO, excluding himself. The CEO’s recommendations on NEO pay are developed in consultation with the Chief Human Resources Officer and the Committee’s compensation consultant, and are considered with Market data. The Committee determines and approves the final compensation elements and amounts to be provided to the Company’s NEOs.

All independent members of the Board (rather than the Committee) have responsibility for approving CEO compensation. The Committee reviewed and recommended proposed changes to CEO compensation to the independent members of the Board for approval.

Role of the Executive Compensation Consultant

In 2017, the Committee engaged FW Cook to provide analysis, advice and recommendations on executive compensation to the Committee. The Committee considered disclosures provided by FW Cook related to its independence from the Company, the Company’s NEOs and the members of the Committee, and reviewed FW Cook’s independence policy. FW Cook does not provide any other services for our Company.

At the Committee’s request, FW Cook performed the following services in 2017:

• reviewed and opined on our executive compensation philosophy;

• reviewed and opined on our Compensation Peer Group;

• provided and analyzed data for various elements of executive compensation;

• reviewed and opined on our executive and Board compensation programs, including NEO and Board target compensation;

• presented executive compensation trends and regulatory updates to the Committee; and

• provided input and perspective on various technical matters pertaining to executive compensation.

The Committee analyzed and considered the information provided by management and FW Cook to determine the program design and the level and mix of each compensation element for the NEOs.

Components and Analysis of 2017 Executive Compensation

Base Salary

In establishing each NEO’s annual base salary, the Committee considered Market data, each individual’s experience and responsibilities, our annual merit budget for all employees, achievement of performance objectives, internal equity and recommendations provided by the CEO for his direct reports.

The following table provides detail regarding base salaries for each NEO:

Name	Title	Base Salary January 1, 2017		Increase Effective April 1, 2017		Base Salary April 1, 2017
Todd M. Bluedorn	Chairman and Chief Executive Officer	$	1,092,000	3.0	%	$	1,125,000
Joseph W. Reitmeier	EVP, Chief Financial Officer	475,000		5.3		500,000
Douglas L. Young	EVP, President and Chief Operating Officer, Residential Heating and Cooling	540,000		3.7		560,000
Daniel M. Sessa	EVP, Chief Human Resources Officer	480,000		3.1		495,000
John D. Torres	EVP, Chief Legal Officer and Corporate Secretary	465,000		3.2		480,000
David W. Moon	Former EVP, President and Chief Operating Officer, Worldwide Refrigeration	500,000		3.0		515,000

In setting NEO base salaries, the Committee used the 50th percentile of the Market as a guideline. The base salary was set within a reasonable range of this guideline for each NEO.

Short-Term Incentive Program

Our short-term incentive program (“STI Program”) as established under the Lennox International Inc. 2010 Incentive Plan, as amended and restated (the “LII 2010 Incentive Plan”), is an annual cash-based program for our NEOs designed to reward the successful performance of our Company, our business units and each individual NEO. In early 2017, the Committee approved the financial metrics and performance goals that must be achieved for any payouts to be made under our STI Program. The 2017 STI Program was funded based on performance against the financial goals set forth below. The 2017 short-term incentive awards were based 75% on financial performance and 25% on each NEO’s individual performance.

Financial Performance. The following table summarizes the performance goals and payout opportunities under our 2017 STI Program, along with Company and business unit performance for each metric.

2017 Short-Term Incentive Program Summary — Financial Performance

($ in thousands)

Name(1)	Metric	Weight	Threshold		Target		Maximum		Performance
All	Company Core Net Income(2)	60%	$	266,307	$	332,884	$	382,817	$	339,833

Payout Opportunity as a % of Target			50%		100%		225%

(1) All NEOs except Mr. Young and Mr. Moon were measured 100% on overall Company financial performance, which resulted in a calculated award of 104% of target. As the President of our Residential Heating and Cooling segment, Mr. Young’s award was measured 50% on Residential Heating and

24

Cooling’s financial performance and 50% on overall Company financial performance. Residential Heating and Cooling’s financial performance resulted in a calculated award of 89% of target, which when blended with the Company’s calculated award of 104% of target, resulted in a calculated award for Mr. Young of 96% of target. As the President of our Worldwide Refrigeration segment, Mr. Moon’s award was measured 50% on Worldwide Refrigeration’s financial performance and 50% on overall Company financial performance. Worldwide Refrigeration’s financial performance resulted in a calculated award of 97% of target, which when blended with the Company’s calculated award of 104% of target, resulted in a calculated award for Mr. Moon of 101% of target.

(2) Company core net income, a non-GAAP financial measure used for incentive compensation purposes, is income from continuing operations, adjusted for 2017 restructuring charges, certain product quality adjustments, certain legal charges and contingency adjustments, unrealized gains and losses on unsettled futures contracts, pension settlement charges and certain other items.

(3) Company free cash flow, a non-GAAP financial measure used for incentive compensation purposes, is net cash provided by operating activities less purchases and sales of property, plant and equipment. Cash usage attributable to discontinued operations; working capital timing, which included unusual inventory pre-build due to regulatory changes; unplanned capital expenditures; and restructuring charges were excluded from Company free cash flow.

(4) Segment profit, a non-GAAP financial measure used for incentive compensation purposes, is earnings from continuing operations for the applicable segment before interest expense, other expenses, and income taxes, adjusted for 2017 restructuring charges, certain product quality adjustments, certain legal charges and contingency adjustments, unrealized gains and losses on unsettled futures contracts, and certain other items.

(5) Segment controllable cash flow, a non-GAAP financial measure used for incentive compensation purposes, is segment profit, defined above, less purchases and sales of property, plant and equipment, plus or minus changes in accounts receivable, inventory and accounts payable.

Individual Performance. The Committee considered individual performance in addition to financial performance in order to further align pay with performance. The individual performance component comprised 25% of the calculated award and had the same payout range as the STI Program (0% to 225%). The individual performance component was measured against specific financial, operational, strategic, and leadership objectives established for each NEO in advance of the performance measurement period as part of our performance management process. After the end of the year, the CEO reviewed with the Committee the extent of achievement of these established objectives by each NEO (other than the CEO). The Committee then determined and approved the individual performance component for each NEO (other than the CEO). The independent members of the Board determined and approved the individual performance component for the CEO.

Targets and Payouts. Under the STI Program, target payout opportunities are determined as a percentage of base salary. The target payout opportunities are based on Market data using the 50th percentile as a guideline. Each NEO’s target percentage fits within this guideline and was unchanged for 2017.

Based on analysis of the Market data and internal equity considerations, the Committee (or with respect to the CEO, the independent Board members) set the following short-term incentive targets for 2017. Based on actual financial and individual performance, the Committee (or with respect to the CEO, the independent Board members) approved the following 2017 payouts for each NEO:

2017 Short-Term Incentive Targets and Payouts

We include the short-term incentive payments made to the NEOs for 2017, which were approved by the Committee on February 26, 2018 and paid on March 15, 2018, in the Summary Compensation Table under “Non-Equity Incentive Plan Compensation.”

Long-Term Incentive Program

We have a long-term incentive program designed to incentivize those employees who have principal responsibility for our long-term profitability. We believe participation in our long-term incentive program aligns the interests of our NEOs with the interests of our stockholders.

We use a mix of performance share units (“PSUs”), restricted stock units (“RSUs”) and stock appreciation rights (“SARs”) in our long-term incentive program. PSUs and SARs reward performance, as measured by achievement of specified financial objectives for PSUs and stock price growth for SARs. RSUs help us retain key members of management through time-based vesting. The Committee allocated the mix of elements in our long-term incentive program in a manner designed to drive Company performance, retain key talent, and provide competitive compensation.

For 2017, the long-term incentive award allocations for our NEOs were as follows:

The Committee determines the grant date for all long-term incentive awards, and has a long-standing practice of granting all awards at its regularly scheduled December meeting. Although awards may also be granted in special circumstances or upon hire for certain executives, no out-of-cycle grants were made to any NEO in 2017. The Committee sets the exercise price of our SARs at 100% of fair market value, which is defined as the average of the high and low New York Stock Exchange (“NYSE”) trading prices of our common stock on the date of grant.

The target award values under our long-term incentive program are based on Market data for similar positions using the 50th percentile as a guideline. The number of shares available for grant under the LII 2010 Incentive Plan is also considered. In December 2017, the Committee established the target award values at or near the 50th percentile of the Market for all NEOs. When determining the actual award sizes for each NEO, the Committee and independent Board members considered the NEO’s time in position, individual performance and potential, the NEO’s impact on the financial performance of the Company, and internal equity.

Once the Committee determined the actual long-term incentive award values for each NEO for the 2017 grants, 50% of the value was provided as PSUs, 30% as RSUs and 20% as SARs.

26

The following table summarizes the award values and number of awards granted for each NEO: 

	December 2017 Award Value								Number of Awards Granted
Name	PSUs		RSUs		SARs		Total		PSUs(1)	RSUs(1)	SARs(2)	Total
Mr. Bluedorn	$	2,500,000	$	1,500,000	$	1,000,000	$	5,000,000	12,929	7,758	31,299	51,986
Mr. Reitmeier	525,000		315,000		210,000		1,050,000		2,715	1,629	6,573	10,917
Mr. Young	625,000		375,000		250,000		1,250,000		3,232	1,939	7,825	12,996
Mr. Sessa	525,000		315,000		210,000		1,050,000		2,715	1,629	6,573	10,917
Mr. Torres	525,000		315,000		210,000		1,050,000		2,715	1,629	6,573	10,917
Mr. Moon	—		—		—		—		—	—	—	—

(1) The number of PSUs and RSUs was determined by dividing the corresponding target award value by the fair market value of our common stock on the NYSE averaged over the 30 calendar days ending on November 29, 2017 ($193.36).

(2) The number of SARs granted was determined by dividing the corresponding target award value by the Black-Scholes value of our common stock based on the 30 calendar day average of our common stock as of November 29, 2017 ($31.95).

PSUs. To maintain our strong focus on long-term Company performance, we granted 50% of the December 2017 long-term incentive award in the form of PSUs. PSUs generally vest at the end of a three-year performance period. If at least the threshold performance level has been achieved at the end of the performance period, the PSUs are distributed in the form of Company common stock based on the actual performance achieved. Dividends are not earned or paid on PSU awards during the three-year performance period. The Committee determines the measurement criteria annually, selecting financial metrics and setting performance goals that will enhance stockholder value. The Committee certifies the financial performance levels following the end of the performance period and the Company distributes any earned shares.

The key attributes of the PSUs granted in December 2014, which vested on December 31, 2017, are summarized in the following table along with the financial performance goals and payout opportunities versus actual performance. In 2017, NEOs earned a payout of 173.1% of target for the PSUs granted in December 2014. The payout value is reflected in the 2017 Option/SAR Exercises and Stock Vested Table in the “Stock Awards — Value Realized on Vesting” column.

December 2014 PSU Grant

(for the January 1, 2015 — December 31, 2017 Performance Period)

Metric	Weight	Measurement Period	Threshold	Target	Maximum	Actual
Return on Invested Capital (“ROIC”)(1)	50%	3-year weighted average (20% lowest year, 40% other two years)	14%	20%	26%	30.8%
Company Core Net Income	50%	3-year compound annual growth rate	6%	12%	22%	16.6%
Payout as a % of Target Award			50%	100%	200%	173.1%

(1) Net operating profit after tax (NOPAT), a component of ROIC and a non-GAAP financial measure used for incentive compensation purposes, is income from continuing operations, adjusted for 2017 restructuring charges, certain product quality adjustments, certain legal charges and contingency adjustments, unrealized gains and losses on unsettled futures contracts, pension settlement charges and certain other items.

The key attributes of the PSUs granted in December 2017 are summarized in the following table. The Committee established the ROIC performance goals based on its assessment of desired return relative to the cost of capital as well as historical and projected ROIC outcomes. Similarly, the Committee set Company core net income growth performance goals based on historical results, projected outcomes of that measure, and expected market conditions. While specific forward-looking performance goals are not included in the table below in light of competitive sensitivities, the degrees of difficulty required to achieve a payout are included.

December 2017 PSU Grant

(for the January 1, 2018 — December 31, 2020 Performance Period)

Metric	Weight	Rationale for Selection	Measurement Period	Threshold	Target	Maximum
ROIC	50%	Measures efficient use of capital; higher ROIC correlates to greater cash flow	3-year weighted average (20% lowest year, 40% other two years)	No payout occurs unless ROIC exceeds the Company’s estimated cost of capital; Target payout occurs at roughly three times the Company’s estimated cost of capital
Company Core Net Income Growth	50%	Measures profitability; higher Company core net income correlates with higher earnings per share	3-year compound annual growth rate	Target payout requires low double digit core net income compound annual growth rate
Payout as a % of Target Award				50%	100%	200%

The PSUs granted to our NEOs in 2017 are included in the 2017 Grants of Plan-Based Awards Table in the “Estimated Future Payouts Under Equity Incentive Plan Awards” column.

RSUs. To support our retention efforts, the Committee granted the NEOs 30% of the December 2017 long-term incentive award in the form of RSUs. RSUs generally vest and are distributed in shares of our common stock three years following the date of grant if the recipient remains an employee of the Company and all other conditions of the award are met. Dividends are not earned or paid on RSUs during the three-year vesting period. The number of shares underlying RSUs granted to our NEOs in 2017 is included in the 2017 Grants of Plan-Based Awards Table in the “All Other Stock Awards: Number of Shares of Stock or Units” column.

SARs. To incentivize NEOs to grow our business and deliver increased returns to our stockholders, the Committee granted the NEOs 20% of the December 2017 award in the form of SARs. SARs vest in one-third increments on each anniversary of the date of grant. Upon the exercise of vested SARs, the increase between the fair market value of our common stock on the date of grant and the fair market value on the date of the SAR exercise is paid in Company common stock. The grant date fair value and the SAR exercise price are determined on the date of grant. SARs granted in 2017 expire seven years from the date of grant. The number of SARs granted to our NEOs in 2017 is included in the 2017 Grants of Plan-Based Awards Table in the “All Other Option Awards: Number of Securities Underlying Options” column.

Perquisites

We believe providing reasonable perquisites is a market-competitive practice to attract and retain top executive talent. Rather than offering individual perquisites, however, we provide a monthly cash stipend to each of our NEOs to allow more flexibility and choice. Our NEOs have full discretion on how the cash stipend is spent and it is not tracked by the Company after the money is paid. In addition, we offer the installation of Company products and equipment at each NEO’s home to promote our brand to business and personal guests. The value of the Company products and equipment is included as taxable income to the NEO.

Benefit Programs

To attract top executive talent and as a market-competitive practice, we provide certain benefit programs to our NEOs that are in addition to those provided to our employees generally. The following table summarizes the additional benefit programs in place during 2017 and the purpose of each program.

Additional Benefit Programs Offered to NEOs in 2017

Plan	Type	Purpose
Supplemental Retirement Plan	Non-Qualified Defined Benefit	Provide market-competitive retirement benefit by providing higher accruals and by permitting accruals that otherwise could not occur because of limitations on compensation under the Code.
Life Insurance Plan	Company-Sponsored Life Insurance	Provide market-competitive life insurance benefits; $3 million in coverage for our CEO and minimum of $1 million for other NEOs.

28

Additional Information Regarding Executive Compensation

Other agreements and policies important to a stockholder’s understanding of the Company’s overall executive compensation program structure are described below.

Employment Agreements and Change in Control Agreements

We have employment agreements and change in control (“CIC”) agreements with each NEO as reviewed and approved by the Committee. We believe employment agreements are helpful in attracting and retaining top executive talent and for financial and business planning purposes. We believe CIC agreements are necessary to (1) retain key executives during periods of uncertainty; (2) enable executives to objectively evaluate, negotiate and execute a CIC transaction; (3) encourage executives to remain focused on running the business rather than seeking other employment in the event of a possible CIC; (4) preserve stockholder value by providing continuity of management during a transition period; and (5) provide benefit to the Company in the form of restrictive covenants, such as non-compete and non-solicitation provisions. We do not provide tax gross-ups for any CIC agreements entered into after 2009.

Our employment agreements and CIC agreements, and the potential costs associated with each, are discussed in detail under “Potential Payments Upon Termination or Change in Control.”

Stock Ownership Guidelines

The Company has stock ownership guidelines for the CEO and other NEOs. We believe stock ownership by executives aligns the interests of executives with the interests of our stockholders and motivates executives to build long-term stockholder value.

The following chart sets forth, as of December 31, 2017, for each NEO, the stock ownership requirements as a multiple of base salary, the total number of shares and unvested RSUs counted toward the stock ownership requirements, and the value of the shares and unvested RSUs as a multiple of base salary. All of our NEOs met our stock ownership guidelines as of December 31, 2017. NEOs are given five years from the date of appointment as an NEO to meet the guidelines. 

Name	Ownership Requirement as a Multiple of Base Salary	Total Number of Shares and Unvested RSUs	Stock Ownership as Multiple of Base Salary(1)
Mr. Bluedorn	5X	173,660	27.1X
Mr. Reitmeier	3X	15,418	5.4X
Mr. Young	3X	55,935	17.6X
Mr. Sessa	3X	45,655	16.2X
Mr. Torres	3X	10,660	3.9X
Mr. Moon	3X	113,908	38.9X

(1) Based on the average daily closing price for 2017 of $175.84.

The Committee oversees and administers the stock ownership guidelines. If an NEO fails to comply with the guidelines, the Committee will determine any appropriate corrective measures to be taken.

Clawback Policy

Our Company has an incentive compensation clawback policy for the CEO and the other NEOs. Under this policy, in the event of any fraud or misconduct that results in a restatement of our Company’s financial results within three years of the filing of the original financial results, the Committee can recoup and cancel cash and equity-based incentive compensation of each person involved in such fraud or misconduct.

29

Prohibition on Hedging / Pledging Policy

The Company’s Insider Trading Policy prohibits directors, NEOs and all other employees from trading in any interest, security or position relating to the future price of Company securities, such as a put, call, swap, short sale, hedge or any other type of derivative security. It also prohibits directors, NEOs and all other employees from pledging Company securities as collateral for a loan, which would include purchases of Company securities on margin.

Tax and Accounting Implications

Section 162(m) Compliance

Effective for taxable years beginning after December 31, 2017, The Tax Cuts and Jobs Act changed certain aspects of federal income taxation of executive compensation, including elimination of the "performance-based" compensation exemption to Section 162(m) which, if certain requirements were satisfied, allowed a company to deduct “performance-based” compensation in excess of $1 million to NEOs.  The Committee will continue to consider the income tax consequences to our Company when analyzing our executive compensation program.  If granting awards or providing other executive compensation is consistent with Market data, our compensation philosophy or our strategic business goals, the Committee may provide executive compensation that is not fully deductible.

Non-qualified Deferred Compensation

In addition to the non-qualified Supplemental Retirement Plan discussed previously, our Company also maintains a frozen non-qualified Profit Sharing Restoration Plan. Both of these deferred compensation plans are administered in compliance with Section 409A of the Code.

Accounting for Stock-Based Awards

When developing NEO compensation, the Committee considered the accounting consequences (in accordance with the requirements of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation — Stock Compensation (“FASB ASC Topic 718”)) of the program design and award levels, and structured the Company’s executive compensation program accordingly.

(1) The amounts shown represent the grant date fair value of the aggregate amount of all stock awards (prior to any assumed forfeitures related to service-based vesting conditions, where applicable) for each year, in accordance with FASB ASC Topic 718, in connection with RSUs and PSUs granted under the LII 2010 Incentive Plan. Assumptions used in calculating these amounts are described in Note 14 of the Consolidated Financial Statements for the fiscal year ended December 31, 2017, included in our Form 10-K filed with the SEC on February 16, 2018. Amounts for 2017 PSUs reflect the most probable outcome for the awards on December 31, 2017 valued at the date of grant in accordance with FASB ASC Topic 718. If the PSUs were valued at maximum performance levels, the total PSU value at grant date would equal:

(2) The amounts shown represent the grant date fair value of the aggregate amount of all SAR awards (prior to any assumed forfeitures related to service-based vesting conditions, where applicable) for each year, in accordance with FASB ASC Topic 718, in connection with SARs granted under the LII 2010 Incentive Plan. Assumptions used in calculating these amounts are included in Note 14 of the Consolidated Financial Statements for the fiscal year ended December 31, 2017, included in our Form 10-K filed with the SEC on February 16, 2018.

(3) The amounts shown represent the aggregate change in the actuarial present value of accumulated pension benefits that accrued during the applicable year under our Supplemental Retirement Plan and frozen Consolidated Pension Plan, each as discussed under “Retirement Plans,” as a result of changes in the valuation discount rate, changes in compensation, and an additional one year of service. No above-market interest on nonqualified deferred compensation was earned.

(4) The amounts shown include perquisites and other compensation. The following table identifies the amounts attributable to each category of perquisites and other compensation in 2017 for each NEO.

	Perquisites				Other Compensation
Name	Cash Stipend		Company Equipment and Installation		Term Life Insurance Premiums		Retirement Contributions		Other	Total
Todd M. Bluedorn	$	30,000	$	—	$	886	$	16,200		$	47,086
Joseph W. Reitmeier	30,000		61,467		308		16,200			107,975
Douglas L. Young	30,000		1,403		99		16,200			47,702
Daniel M. Sessa	30,000		—		276		16,200			46,476

David W. Moon	30,000		38,165		286		16,200		2,022,734	2,107,385

The values attributable to each item listed above are calculated as follows:

• Cash Stipend — actual cash paid to each NEO in lieu of individual perquisites.

• Company Equipment and Installation — Company equipment is based on the purchase price of the equipment, adjusted in accordance with our employee rebate program. Installation of this equipment is based on the cost for installation paid by the Company in 2017.

32

• Term Life Insurance Premiums — The amounts shown are based on the incremental cost paid in 2017 on behalf of each NEO for Basic Life and Basic Accidental Death and Dismemberment over and above the premiums we would otherwise pay under our life insurance program for other employees.

• Retirement Contributions — based on Company contributions made under our qualified 401(k) Plan in 2017.

(5) During 2017, named executive officer, Mr. Moon, was removed from his position as Executive Vice President, President and Chief Operating Officer, Worldwide Refrigeration.  In connection with his removal, and pursuant to the terms of his employment agreement with the Company, he entered into a Separation and General Release Agreement containing a release of claims and certain restrictive covenants regarding confidentiality, non-competition, non-solicitation, and non-disparagement obligations, and which provided for him to be paid $2,022,734 in cash and certain medical benefits. The Separation and General Release Agreement was filed on the Company’s Annual Report on Form 10-K. The amount reported in the "All Other Compensation" column includes severance related payments, perquisites, and other compensation further explained in Note 4 above.

Retirement Plans

Qualified Retirement Plans

Frozen Consolidated Pension and Profit Sharing Retirement Plans

Effective January 1, 2009, the Company’s Consolidated Pension Plan and Profit Sharing Retirement Plan were frozen. As of that date, benefits under the frozen Pension Plan stopped increasing with additional service and compensation, and additional contributions to the Profit Sharing Plan were discontinued.

The monthly target benefit under the frozen Pension Plan is based on 1.0% of final average annual pay, plus 0.6% of final average annual pay above Social Security covered compensation, multiplied by the number of years of credited service (not to exceed 30 years). The target benefit is reduced by the value of the participant’s defined contribution profit sharing account under the frozen Profit Sharing Plan, with the difference, if any, provided by the frozen Pension Plan. Participants become vested in their frozen Pension Plan accrued benefits after five years of service and may commence unreduced benefits at age 65 (normal retirement age) or actuarially reduced benefits at younger ages if age and service requirements are met (generally the attainment of age 62 and 10 years of service or if age plus years of service total 80). Benefits are generally paid in the form of an annuity. We do not grant extra years of service under the Consolidated Pension Plan. Participants in the frozen Profit Sharing Plan are fully vested in the plan after six years of service and the Company directs the investment funds. Distributions may occur at separation from service and are eligible for roll-over into another qualified retirement plan.

401(k) Salaried Retirement Plan

Salaried employees are eligible to participate in this plan, and contributions can be made on a pre-tax or Roth post-tax basis, subject to limitations for qualified plans under the Code. Participants can contribute up to

75% of their eligible earnings and receive a Company match of 50% on up to 6% of their eligible pay. In addition, all participants (after completing one year of service) receive a base contribution equal to 3% of eligible pay. The match vests after the participant completes two years of service and the base contribution is fully vested.

37

Non-Qualified Retirement Plans

Supplemental Retirement Plan

The purpose of our Supplemental Retirement Plan is to provide Market-competitive executive level retirement benefit opportunities. It permits income above Code limitations to be considered in determining final average annual pay, doubles the rate of benefit accrual available under the frozen Pension Plan (2.0% of final average annual pay, plus 1.2% of final average annual pay above Social Security covered compensation), limits credited service to 15 years, generally permits early retirement on more favorable terms than the frozen Pension Plan (for example, unreduced benefits at age 62 with 10 years of service or unreduced benefits at age 60 if age plus years of service total 80), and pays benefits in the form of a lump-sum. Any benefits provided under the Supplemental Retirement Plan are reduced by the benefits payable under our Company’s frozen Pension Plan (as if such plan had not been frozen), frozen Profit Sharing Plan, and frozen Profit Sharing Restoration Plan. Participants become vested in their Supplemental Retirement Plan benefit after five years of service. Extra years of credited service are not provided to participants except for up to an additional three years of service and age (subject to the 15 year service limit) in the case of a change in control. The incremental effects of additional years of service are reflected in the tables included in “Potential Payments Upon Termination or Change in Control.”

Frozen Profit Sharing Restoration Plan

We froze the Profit Sharing Restoration Plan and discontinued contributions effective January 1, 2009. Distributions may occur at separation from service and may be paid as a lump-sum or in equal annual installments over either a five- or ten-year period. We direct the investment funds for the frozen Profit Sharing Restoration Plan, which mirror the investments and returns under the frozen Profit Sharing Retirement Plan. The weighted average annual rate of return for the calendar year ended December 31, 2017, was 14.8%.

2017 Pension Benefits

The following table provides information regarding the number of years of service credited to each NEO and the present value of accumulated benefits payable to each NEO under our frozen Consolidated Pension Plan and our Supplemental Retirement Plan as of December 31, 2017, as well as payments made to each NEO in 2017 under such plans.

(1) The actuarial present value of the lump-sum accumulated benefit payable at December 31, 2017 is equal to the annualized present value factor, multiplied by the monthly benefit. The amounts shown are calculated in accordance with FASB ASC Topic 715, using a 3.23% interest (discount) rate for the Supplemental Retirement Plan and 3.70% for the Consolidated Pension Plan as of December 31, 2017 and the RP-2014 Healthy Retiree

Mortality Table, adjusted to 2006, and projected generationally with Scale MP-2017. The calculations assume payments are deferred until age 65 for all participants under our frozen Consolidated Pension Plan and until the earliest unreduced retirement age for each participant under our Supplemental Retirement Plan. Additional assumptions are included in Note 12 of the Consolidated Financial Statements for the fiscal year ended December 31, 2017, included in our Form 10-K filed with the SEC on February 16, 2018.

Potential Payments Upon Termination or Change in Control

Employment Agreements and Change in Control Agreements

We are party to employment agreements and CIC agreements with each NEO. These agreements serve as the basis for the payments and benefits to which each NEO would be entitled in the event of termination of such individual’s employment with our Company under the various circumstances described below.

Employment Agreements

The employment agreements with our NEOs establish the basis of compensation and responsibilities for each NEO and contain post-employment covenants, including confidentiality, prohibition against the diversion of employees, vendors and contractors and prohibition against the solicitation of customers, for a period of 24 months following termination of employment. On January 1 of each year, the agreements automatically renew for an additional year, unless either party notifies the other in writing at least 30 days prior to such date of its decision not to renew the agreement. Except as otherwise provided below, the terms and conditions of our employment agreement with each NEO are substantially similar.

Change in Control Agreements

Our CIC agreements with our NEOs, the terms and conditions of which are substantially similar except as noted below, provide for benefits under specified circumstances if a NEO’s employment is terminated in connection with a CIC transaction. The agreements require the NEO to maintain the confidentiality of our information and not to induce our employees to terminate their employment with our Company, for a period of 24 months following termination of employment.

All CIC agreements entered into after 2009 do not include a tax gross-up provision.

39

Payments Made Upon Voluntary Termination or Upon For Cause Termination

If a NEO voluntarily terminates his employment with our Company or we terminate a NEO for cause, he will be entitled to receive base salary through the last day of employment and a lump-sum payment equal to unused, accrued vacation days. Unvested SARs, RSUs and PSUs will terminate on the NEO’s last day of employment. Vested SARs will be exercisable for 90 days after the last day of employment if the NEO voluntarily terminates his employment.

Payments Made Upon Retirement

If a NEO retires, he will be entitled to receive his base salary through the last day of employment, a payment under our short-term incentive program based on actual company performance (prorated through the NEO’s last day of employment) and a lump-sum payment equal to unused, accrued vacation days. In addition, with respect to long-term incentive awards:

• unvested SARs will terminate on the NEO’s last day of employment and vested SARs will remain exercisable for the remainder of the term of the award;

• for RSUs, the NEO will receive a prorated portion of shares based on the date of retirement at the end of the applicable vesting period; and

• for PSUs, the NEO will receive, to the extent earned based on achievement of specific performance measures, a prorated portion of shares based on the date of retirement at the end of the applicable performance period.

Payments Made Upon Involuntary — Not for Cause Termination

If we terminate a NEO prior to the expiration of his employment agreement (including non-renewal of the NEO’s agreement) for any reason other than for cause, the NEO will generally be entitled to receive “normal severance compensation” or, in the NEO’s sole discretion, “enhanced severance benefits.” Under both severance packages:

• all vested SARs will continue to be exercisable for 90 days following the NEO’s last day of employment; and

• unvested equity awards (SARs, RSUs and PSUs) will terminate on the NEO’s last day of employment.

Normal Severance Compensation. If the NEO elects to receive “normal severance compensation,” he will receive monthly payments equal to the greater of (1) his monthly base salary for the remainder of the employment agreement’s term, or (2) three months of his monthly base salary in addition to any other compensation or benefits applicable to an employee at the NEO’s level, including a lump-sum payment equal to unused, accrued vacation days.

Enhanced Severance Benefits. If the NEO agrees to execute a written general release of any and all possible claims against us existing at the time of termination, we will provide the employee with “enhanced severance benefits.” Payments provided under this severance arrangement, which are dependent on years of service with our Company, generally include the following:

Component	Less than Three Years of Service	Three or More Years of Service
Base Salary	One year of base salary	Two years of base salary
Short-Term Incentive	Lump-sum payment equal to all payments under our short-term incentive programs received by the NEO in the previous 12 months	Lump-sum payment equal to all payments under our short-term incentive programs received by the NEO in the previous 24 months
Payment in Lieu of Outplacement Services	Lump-sum payment equal to 10% of base salary	Same
Payment in Lieu of Perquisites	Lump-sum payment equal to 10% of base salary	Same
Post-Employment Health Care Coverage	Payment of COBRA premiums for up to 18 months while the NEO is unemployed and not eligible for other group health coverage and payment of the equivalent of such premium for up to an additional six months, should the NEO remain unemployed	Same
Death Benefit	If the NEO dies during the enhanced severance period, a lump-sum death benefit equal to six months of the NEO’s base salary will be paid to the NEO’s beneficiary	Same
Accrued Vacation	A lump-sum payment equal to unused, accrued vacation days	Same

40

Payments Made Upon Death or Disability

Generally, if a NEO dies during the term of his employment agreement, the NEO’s beneficiary will be entitled to receive “normal severance compensation,” as described above. If a NEO becomes permanently disabled during the agreement term, he will generally be entitled to, at the NEO’s option, either “normal severance compensation” or “enhanced severance benefits,” as described above. In the case of either death or disability, with respect to long-term incentive awards:

• all SARs will vest immediately and remain exercisable for the duration of the term;

• for RSUs, the NEO, or his beneficiary, will receive a prorated payment based upon the portion of the vesting period the NEO actually served as an employee payable at the time employment ceases; and

• for PSUs, the NEO, or his beneficiary, will receive, to the extent earned based on achievement of performance measures, a prorated portion of shares based upon the portion of the performance period the NEO actually served as our employee, payable at the time employment ceases.

Payments Made to Mr. Bluedorn if he Terminates his Employment for “Good Reason,” Upon Involuntary — Not for Cause Termination, or Upon Death or Disability

Except as described below, Mr. Bluedorn will receive similar severance benefits as the other NEOs. Mr. Bluedorn’s employment agreement provides for certain severance benefits in the event he terminates his employment for “good reason.” “Good reason” includes:

• any change in Mr. Bluedorn’s position, authority, duties, or responsibilities inconsistent with the position of CEO (excluding de minimus changes and an isolated, insubstantial and inadvertent action not taken in bad faith and promptly remedied by the Company after notice);

• any failure by the Company to comply with any of the provisions of Mr. Bluedorn’s employment agreement (excluding an isolated, insubstantial and inadvertent action not taken in bad faith and promptly remedied by the Company after notice);

• any requirement for him to be based at any office or location other than our current headquarters in Richardson, Texas;

• any purported termination by the Company of Mr. Bluedorn’s employment otherwise than as expressly permitted by his employment agreement; or

• any failure by our Board to nominate him for election by the stockholders as a director.

Pursuant to his employment agreement, in the event (1) Mr. Bluedorn terminates his employment for “good reason,” (2) we terminate him prior to the expiration of his employment agreement (including non-renewal of his agreement) for any reason other than for cause, or (3) Mr. Bluedorn dies or becomes permanently disabled during the term of his employment agreement, he (or his beneficiary, as applicable) will be entitled to receive “enhanced severance benefits” as described above under “Payments Made Upon Involuntary — Not For Cause Termination,” provided he (or his personal representative, as applicable) agrees to execute a written general release of any and all possible claims against us existing at the time of termination.

In the case of either death or permanent disability, Mr. Bluedorn’s long-term incentive awards will vest, remain exercisable and be paid or distributed as described above under “Payments Made Upon Death or Disability.”

Payments Made Upon a Change in Control

Definition of Change in Control

A CIC generally includes the occurrence of any of the following events: 

• an acquisition by a third party of 35% or more of our voting stock;

• a change in a majority of Board members without majority Board approval;

• stockholder approval of a merger, consolidation or reorganization;

• stockholder approval of the liquidation or dissolution of our Company; or

• stockholder approval of the sale of substantially all corporate assets.

41

Definition of Good Reason

“Good reason,” under each CIC agreement, includes: 

• any change in the NEO’s position, authority, duties, or responsibilities (excluding de minimus changes);

• any failure to comply with the NEO’s CIC agreement, including without limitation the provision regarding compensation and benefits;

• a required relocation to any office or location not within 35 miles of the NEO’s current office or location;

• any failure by any successor to adopt and comply with the NEO’s CIC agreement; or

• any failure to re-elect to the Board any NEO serving as a member of the Board.

Change in Control Benefits

If a NEO’s employment is terminated without cause or by the NEO for “good reason” either (1) within two years following a CIC, or (2) within six months prior to a CIC, we will provide the NEO with the following CIC benefits: 

Component	CIC Benefit
Base Salary Severance	Lump-sum payment equal to three times the NEO’s annual base salary
Prorated Bonus	Lump-sum payment equal to the NEO’s target bonus, prorated based on the last day of employment
Bonus Severance	Lump-sum payment equal to three times the NEO’s target bonus
Payment in Lieu of Outplacement Services	Lump-sum payment equal to 15% of current base salary
Payment in Lieu of Perquisites	Lump-sum payment equal to 45% of current base salary
Post-Employment Health Care Coverage	Payment of COBRA premiums for up to 36 months while the NEO is unemployed and not eligible for other group health coverage
Supplemental Retirement Plan and Profit Sharing Restoration Plan	Three years added to each of the service and age criteria
Tax Gross-up(*)	If CIC payments are subject to the excise tax imposed by Section 4999 of the Code, an additional “gross-up payment”
Accrued Vacation	A lump-sum payment equal to unused, accrued vacation days

(*) The CIC agreement with Mr. Reitmeier does not include a tax gross up provision.

Upon a CIC, all outstanding SARs, RSUs and PSUs held by the NEO will immediately vest and become exercisable, with applicable performance measures for outstanding PSUs deemed to have been satisfied at the highest possible level (200% of target). Further, outstanding SARs may be exercised by the NEO up to 90 days after a NEO’s termination within one year following a CIC.

David W. Moon

During 2017, Mr. Moon was removed from his position as Executive Vice President, President and Chief Operating Officer, Worldwide Refrigeration.  The payments he received in connection with his Separation and General Release Agreement are included in Note 4 to the Summary Compensation Table.

CEO Pay Ratio

For 2017, the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees of our company other than our CEO was approximately 181 to 1. This pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions summarized below.

Date Used to Identify Median Employee	October 31, 2017
Employee Pool Used to Identify Median Employee	Our employee population consisted of approximately 11,987 individuals on October 31, 2017. In determining the median employee, we excluded employees from certain non-U.S. countries under the de minimis exemption under applicable SEC regulations. The list of excluded countries, together with the number of employees excluded in each country, was as follows: Belgium (7); China (202); Netherlands (51); New Zealand (24); Poland (46); Portugal (22); Singapore (5); and the United Kingdom (6). In total we excluded 363 employees under the de minimis exemption, representing approximately 3% of our total employee population as of October 31, 2017. Our pay ratio includes 11,624 employees.
Compensation Used to Identify Median Employee	Total gross wages as derived from the company’s payroll records.
Median Employee Annual Compensation	$63,201, which includes the value of the median employee’s health and welfare benefits and retirement benefits. We calculated the median employee’s compensation in the same manner as we calculated total compensation of the CEO in the Summary Compensation Table and then added the value of health and welfare benefits.
CEO Compensation	$11,467,545, which is a $12,985 increase over the amount disclosed in the Summary Compensation Table. The increase reflects the value of health and welfare benefits which are excluded from the Summary Compensation Table under SEC rules.
Pay Ratio	181:1

46

DIRECTOR COMPENSATION

In 2017, our director compensation program consisted of annual retainers and long-term incentive compensation. We use a combination of cash, stock and long-term equity awards to compensate members of our Board. Mr. Bluedorn, our Chairman and CEO, does not receive any additional compensation for serving on our Board.

Each year, the Committee reviews benchmark data from our Compensation Peer Group and other general industry surveys to assess the competitiveness of our director compensation program. If the Committee believes changes are warranted to the Board compensation program, the Committee recommends the proposed changes to the independent members of the Board for approval.

2017 Annual Compensation

In 2017, we provided the following annual retainers, which are paid in quarterly installments, and long-term incentive awards to members of our Board.

Board Retainer	Lead Director / Committee Chair Retainer			Long-Term Incentive Award
$100,000 with up to $80,000 payable in cash and the remainder payable in Company common stock	•    Lead Director:	$	25,000	$115,000 RSU Award
	•    Audit:	$	20,000
	•    Compensation and Human Resources:	$	15,000
	•    Board Governance:	$	15,000
	•    Public Policy:	$	10,000

Non-Employee Directors’ Compensation and Deferral Plan

Under this plan, non-employee directors may receive all or a portion of their annual retainer for service on the Board in Company common stock.

Long-Term Incentive Compensation

Non-employee directors receive 100% of their long-term incentive in the form of RSUs under the LII 2010 Incentive Plan. In 2017, we awarded each non-employee director 595 RSUs. Generally, the RSUs vest three years following the date of grant provided that the director remains on our Board throughout the vesting period.

Retirement and Health and Welfare Plans

We provide a frozen Directors’ Retirement Plan for non-employee directors who were active Board members prior to 1998 and allow those directors to participate in our health care program under the same terms and provisions that we provide to our employees. The frozen Directors’ Retirement Plan provides for partial continuation of the cash component of the director’s annual retainer at the time of retirement for life. During 2017 Mr. Major was the only active and continuing Board member eligible to participate in the Directors’ Retirement Plan and the only active Board member who participates in our health care program.

Perquisites and Other Compensation

We allow our non-employee directors to participate in our employee rebate program, which provides rebates on eligible residential heating and air conditioning equipment, accessories, and supplies. We reimburse all non-employee directors for their reasonable expenses incurred in connection with attendance at Board or Board committee meetings.

47

Stock Ownership Guidelines

Pursuant to our Corporate Governance Guidelines, each non-employee director is required to own shares of our common stock having a value of at least three times their annual retainer within three years after their election, and four times their annual retainer within five years after their election. Unvested RSUs and shares of common stock owned count towards this requirement. As of December 31, 2017, all non-employee directors met our stock ownership guidelines.

2017 Director Compensation Table

The following table provides information regarding compensation earned in 2017 by each non-employee director:

(2) For Mr. Stinson, the amount represents the incremental expense associated with the vesting of outstanding RSUs upon his retirement from the Board on March 17, 2017. For the other non-employee directors, the amounts shown represent the grant date fair value (prior to any assumed forfeitures related to service-based vesting conditions, where applicable) in accordance with FASB ASC Topic 718, in connection with RSUs granted under the LII 2010 Incentive Plan. The grant date fair value of RSUs granted to non-employee directors in 2017, calculated in accordance with FASB ASC Topic 718, is as follows:

	Grant Date	RSUs Granted in 2017 (#)	Grant Date Fair Value Per Share ($)(a)	Grant Date Fair Value ($)
Each Non-Employee Director	December 8, 2017	595	197.535	117,533

(a) $197.535 is the dividend discounted value, based on a dividend yield of 1.32%, of the average of the high and low NYSE trading prices of our common stock on the date of the grant, which was $205.530.

(3) The amount shown represent the change in the present value of accumulated pension benefits that accrued during 2017 under our Directors’ Retirement Plan, based on a 3.37% discount rate. Although the actual change in the present value of accumulated pension benefits was negative, $0 is shown for Mr. Major as required by SEC rules.

The following table provides information regarding the aggregate number of outstanding RSUs held by each non-employee director as of December 31, 2017. RSUs generally vest on the third anniversary of the date of grant.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

All related party transactions must be approved in accordance with the written Related Party Transactions Policy adopted by our Board. A related party transaction is a transaction or relationship since the beginning of the Company’s last fiscal year in which (1) the total amount involved will or may be expected to exceed $120,000, (2) the Company or any of its subsidiaries is a participant, and (3) any related party has or will have a direct or indirect interest (other than solely as a result of being a director or a less than 10 percent beneficial owner of an equity interest in another entity). A related party is any person who is or was since the beginning of the previous fiscal year an executive officer, director or nominee for election as a director, a stockholder owning more than 5% of the Company’s voting securities, or an immediate family member of any of these persons.

Our Board has considered certain limited types of transactions with related persons that meet specified criteria and determined that each of them is deemed to be pre-approved under the terms of the Related Party Transaction Policy. These include (1) transactions with companies and charitable contributions to organizations at which a related party’s only relationship is as an employee (other than an executive officer), if the amount of the transaction or contribution does not exceed the greater of $1,000,000 or 1% of that Company’s total annual revenue, (2) transactions involving competitive bids, (3) regulated transactions, and (4) certain routine banking services.

Our Audit Committee is generally responsible for approving all related party transactions, which must be on terms that are fair to our Company and comparable to those that could be obtained in arm’s length dealings with an unrelated third party. In the event a related party transaction involves one or more members of the Audit Committee, the transaction must be approved by an ad hoc committee appointed by the Board and composed entirely of independent and disinterested directors. There were no transactions with related persons in 2017 that require disclosure pursuant to Item 404(a) of Regulation S-K.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation and Human Resources Committee was an officer or employee of our Company or any of our subsidiaries during 2017 or at any other time, and no member had any relationship with the Company requiring disclosure under “Certain Relationships and Related Party Transactions” above. In addition, none of our executive officers served on the board of directors or on the compensation committee of any other entity, for which any executive officers of such other entity served either on our Board or on our Compensation and Human Resources Committee.

OWNERSHIP OF COMMON STOCK

The following table provides information regarding the beneficial ownership of our common stock as of March 1, 2018 by (1) each person known to own beneficially more than 5% of our common stock, (2) each of our directors, (3) each of our NEOs, and (4) all current directors and executive officers as a group.

For purposes of this table, “beneficial ownership” (as defined in Rule 13d-3 of the Exchange Act of ) takes into account shares as to which the individual has or shares voting or investment power as well as shares that may be acquired within 60 days (such as by exercising vested SARs, receiving earned performance shares or the vesting of RSUs) and is different from beneficial ownership for purposes of Section 16 of the Exchange Act. As a result, the numbers below may differ from the numbers reported in forms filed pursuant to Section 16 (e.g., Forms 4).

To our knowledge and unless otherwise indicated, each stockholder listed below has sole voting and investment power over the shares listed as beneficially owned by such stockholder. Percentage of ownership is based on 41,318,011 shares of common stock outstanding as of March 20, 2018. Number of shares held by beneficial owners of more than 5% of our common stock and percentage ownership are as of the date of the applicable SEC filing made by those owners (unless otherwise noted).

OTHER INFORMATION

Proxy Solicitation

We will pay for the cost of this proxy solicitation. In addition to solicitation by mail, our directors, officers and employees may solicit proxies from stockholders by telephone, facsimile, email or in person. They will not be paid for soliciting proxies but may be reimbursed for out-of-pocket expenses related to the proxy solicitation. We have retained Georgeson LLC to assist in the solicitation of proxies for a fee of $12,000 plus reimbursement of expenses. We will also make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send the proxy materials to beneficial owners of our common stock. Upon request, we will reimburse the brokerage houses and custodians for their reasonable expenses in so doing.

Multiple Stockholders Sharing the Same Address

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, stockholders who have the same address and last name will receive only one copy of our Notice of Annual Meeting of Stockholders, Proxy Statement, Annual Report to Stockholders, and Annual Report on Form 10-K, unless one or more of these stockholders notifies us by contacting our Investor Relations department indicated below that they wish to continue receiving individual copies. This procedure helps reduce our printing costs and postage fees.

Stockholders who participate in householding will continue to receive separate Proxy Cards. Also, householding will not in any way affect dividend check mailings.

If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the Notice of Annual Meeting of Stockholders, Proxy Statement, Annual Report to Stockholders, and Annual Report on Form 10-K, or if you hold stock in more than one account, and, in either case, you wish to receive only a single copy of each of these documents for your household, please contact our Investor Relations department by telephone at (972) 497-5000 or in writing at 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Investor Relations.

If you participate in householding and wish to receive a separate copy of these documents, please notify our Investor Relations department as indicated above and we will promptly send you a separate copy.

Form 10-K

Our Annual Report on Form 10-K (excluding exhibits) is a part of our 2017 Annual Report to Stockholders, which is being sent with this Proxy Statement. If you are entitled to vote at the Annual Meeting of Stockholders, you may obtain a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017,including the financial statements required to be filed with the SEC, without charge, by contacting our Investor Relations department by telephone at (972) 497-5000 or in writing at 2140 Lake Park Blvd., Richardson, Texas 75080, Attention: Investor Relations.
