PROPOSAL 1: Election of Directors

Four directors are nominated for election to a class that will serve until the 2020 annual meeting of shareholders and until their successors have been duly elected and qualified, or their earlier retirement or resignation. It is intended that the shares represented by each proxy will be voted, in the discretion of the proxies, FOR the nominees for directors set forth below, each of whom is an incumbent, or for any substitute nominee or nominees designated by our Board of Directors in the event any nominee or nominees become unavailable for election. In the event that an incumbent director receives a greater number of votes against his or her election than votes for such election, he or she is required to tender his or her resignation for consideration by the Nominating and Governance Committee of the Board of Directors in accordance with our Bylaws, as described on page 20 under "Director Resignation Policy." The principal occupations of, and certain other information regarding, the nominees and our continuing directors are set forth below. In addition, information about each director's specific experience, attributes and skills that led the Board to the conclusion that each of the directors is highly qualified to serve as a member of the Board is set forth below.

Mr. Bunch retired as PPG's Executive Chairman of the Board and as a director on September 1, 2016. The Company thanks Mr. Bunch for his over 30 years of dedicated service to PPG, including serving as a director since 2002 and as Chairman of the Board since 2005. Mr. Bunch's extraordinary leadership significantly strengthened the financial performance of the Company, creating one of the greatest growth periods in its history and transforming it into one of the leading coatings companies in the world.

Mr. Usher resigned from our Board of Directors effective at the 2016 annual meeting of shareholders. The Company thanks Mr. Usher for his many years of dedicated service to PPG.

The Board believes that each of the Company's directors is highly qualified to serve as a member of the Board. Each of the directors has contributed to the mix of skills, core competencies and qualifications of the Board. Our directors are highly educated and have diverse backgrounds and talents and extensive track records of success in what we believe are highly relevant positions with some of the most admired organizations in the world. Many of our directors also benefit from an intimate knowledge of our operations and corporate philosophy. The Board believes that each director's service as the chairman, chief executive officer, chief operating officer, president or group president of a well-respected company has provided the directors with skills that are important to serving on our Board. The Board has also considered the fact that all of our directors have worked for, or served on the boards of directors of, a variety of companies in a wide range of industries. Specifically, the Board has noted that our directors have skills that, among others, have made them particularly suited to serve as a director of PPG, a global manufacturer of high technology paints, coatings, specialty materials and fiber glass for industrial and consumer markets, with operations in more than 70 countries. The Board believes that through their varying backgrounds, our directors bring a wealth of experiences, new ideas and solutions to our Board.

Vote Required

Each director nominee who receives a majority of the votes cast (the number of shares voted "for" the director must exceed 50% of the votes cast with respect to that director) at the Annual Meeting will be elected as a director.

CORPORATE GOVERNANCE

Board Composition

PPG's business, property and affairs are managed under the direction of the Board of Directors. The Board is currently comprised of 10 members, divided into three classes. Terms of the classes are staggered, with one class standing for election each year. The Board is elected by our shareholders to oversee management of the Company in the long-term interests of all shareholders. The Board also considers the interests of other constituencies, which include customers, employees, retirees, suppliers, the communities we serve and the environment. The Board strives to ensure that PPG conducts business in accordance with the highest standards of ethics and integrity.

Corporate Governance Guidelines

The Board has adopted Corporate Governance Guidelines. These guidelines are revised from time to time to better address particular needs as they change over time. In 2014, the Board revised the Corporate Governance Guidelines to include additional responsibilities for the Company's Lead Director. In 2015, the Board revised the Corporate Governance Guidelines to better delineate the responsibilities of the Chairman of the Board and those of the Chief Executive Officer. The Corporate Governance Guidelines may be accessed from the Corporate Governance section of our website at www.ppg.com/investor.

The Board has a program for orienting new directors and for providing continuing education for all directors, including the reimbursement of expenses for continuing education. The Board annually evaluates its own performance and that of the individual committees. The evaluation process is coordinated by the Nominating and Governance Committee and has three parts: committee self-assessments, full Board evaluations and evaluations of the individual directors in the class whose term is expiring at the next annual meeting. The committee self-assessments consider whether and how well each committee has performed the responsibilities listed in its charter. The full Board evaluations consider the committee self-assessments, as well as the quality of the Board's meeting agendas, materials and discussions. All assessments and evaluations focus on both strengths and opportunities for improvement.

Director Independence

In accordance with the rules of the New York Stock Exchange, the Board affirmatively determines the independence of each director and nominee for election as a director in accordance with the categorical guidelines it has adopted, which include all objective standards of independence set forth in the exchange listing standards. The categorical independence standards adopted by the Board are contained in the Corporate Governance Guidelines, which may be accessed from the Corporate Governance section of our website at www.ppg.com/investor. Based on these standards, at its meeting held on February 16, 2017, the Board determined that each of the following non-employee directors is independent and has no material relationship with PPG, except as a director and shareholder:

In addition, based on such standards, the Board affirmatively determined that Michael H. McGarry is not independent because he is an officer of PPG.

Board Leadership Structure and Risk Oversight

We have a traditional board leadership structure under which Mr. McGarry serves as our Chief Executive Officer and Chairman of the Board. We currently have nine other directors, each of whom is independent. Our Board has four standing committees, each of which is comprised solely of independent directors with a committee chair. The Board believes that Mr. McGarry is best situated to serve as Chairman because he is the director most familiar with our business and industry and the director most capable of identifying strategic priorities and executing our business strategy. The Board believes the combined role of Chairman and Chief Executive Officer serves as a highly effective bridge between the Board and management and provides the leadership to execute our business strategy and create shareholder value. We believe our Board leadership structure provides the appropriate balance of independent directors and management directors to work together to represent the interests of our entire shareholder base.

​

Table of Contents

In addition, having one person serve as both Chairman and Chief Executive Officer demonstrates to our employees, suppliers, customers, shareholders and other stakeholders that PPG has strong leadership setting the tone and having the responsibility for managing our operations. Having a single leader eliminates the potential for confusion and provides clear leadership for PPG. We believe that our Board consists of directors with significant leadership skills, as discussed above. All of our independent directors have served as the chairman, chief executive officer, president or group president of other companies. Accordingly, we believe that our independent directors have demonstrated leadership in large enterprises and are well versed in board processes and that having directors with significant leadership skills benefits our Company and our shareholders.

In accordance with our Bylaws and our Corporate Governance Guidelines, the Chairman is responsible for chairing Board meetings and setting the agenda for these meetings. Each director also may suggest items for inclusion on the agenda and may raise at any Board meeting subjects that are not on the agenda for that meeting. As required by our Corporate Governance Guidelines, our independent directors meet separately, without management present, at each meeting of the Board. In addition, each of the Board's standing committees regularly meets without members of management present.

The Board has designated the chair of the Nominating and Governance Committee to serve as the Lead Director. In their discretion, the independent directors may select another independent director to serve as the Lead Director. Aside from chairing meetings of the independent directors, the Lead Director presides at all meetings where the Chairman is not present, serves as a liaison between the independent directors and the Chairman and Chief Executive Officer, has the power to call meetings of the independent directors, consults with the Chairman and Chief Executive Officer about the concerns of the Board, approves Board meeting agendas and other types of information sent to the Board, approves meeting schedules to assure that there is sufficient time for discussion of all agenda items, and is available for consultation and direct communication with major shareholders as appropriate.

As part of its annual self-evaluation process, the Board evaluates our leadership structure to ensure that it provides the optimal structure for PPG. We believe that having a director with day-to-day oversight of Company operations, coupled with experienced independent directors who have appointed a Lead Director and four committee chairs, is the appropriate leadership structure for PPG.

In accordance with New York Stock Exchange requirements, our Audit Committee charter provides that the Audit Committee is responsible for overseeing our risk management process. The Audit Committee is updated on a regular basis on relevant and significant risk areas. This includes periodic updates from certain officers of the Company and a formal annual update by the Director of Corporate Audit Services. The annual update provides a comprehensive review of PPG's enterprise risks and includes the feedback of most of the Company's officers. The Audit Committee, in turn, reports to the full Board. While the Audit Committee has primary responsibility for overseeing risk management, our entire Board is actively involved in overseeing risk management for the Company by engaging in periodic discussions with Company officers and other employees as the Board may deem appropriate. In addition, each of our Board committees considers the risks within its areas of responsibility. For example, our Technology and Environment Committee considers risks related to our environment, health, safety, product stewardship and other sustainability policies, programs and practices. Our Audit Committee focuses on risks inherent in our accounting, financial reporting, cybersecurity and internal controls. Our Officers—Directors Compensation Committee considers the risks that may be implicated by our executive compensation program. We believe that the leadership structure of our Board supports the Board's effective oversight of the Company's risk management.

Review and Approval or Ratification of Transactions with Related Persons

The Board and its Nominating and Governance Committee have adopted written policies and procedures relating to approval or ratification of "Related Person Transactions." Under these policies and procedures, the Nominating and Governance Committee (or its chair, under some circumstances) reviews the relevant facts of all proposed Related Person Transactions and either approves or disapproves of the entry into the Related Person Transaction, by taking into account, among other factors it deems appropriate:

•

The benefits to PPG of the transaction;

•

The impact on a director's independence, in the event the "Related Person" is a director or an immediate family member of a director or an entity in which a director is a partner, shareholder or executive officer;

•

The availability of other sources for comparable products or services;

•

The terms of the transaction; and

​

​

---

Table of Contents

•

The terms available to unrelated third parties or to employees generally.

No director may participate in any consideration or approval of a Related Person Transaction with respect to which he or she or any of his or her immediate family members is the Related Person. Related Person Transactions are approved only if they are determined to be in, or not inconsistent with, the best interests of PPG and its shareholders.

If a Related Person Transaction that has not been previously approved or previously ratified is discovered, the Nominating and Governance Committee, or its chair, will promptly consider all of the relevant facts. In addition, the committee generally reviews all ongoing Related Person Transactions on an annual basis to determine whether to continue, modify or terminate the Related Person Transaction.

Under our policies and procedures, a "Related Person Transaction" is generally a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which PPG was, is or will be a participant and the amount involved exceeds $120,000, and in which any Related Person had, has or will have a direct or indirect material interest. A "Related Person" is generally any person who is, or at any time since the beginning of PPG's last fiscal year was, (i) a director or executive officer of PPG or a nominee to become a director of PPG; (ii) any person who is known to be the beneficial owner of more than 5% of any class of PPG's voting securities; or (iii) any immediate family member of any of the foregoing persons.

Certain Relationships and Related Transactions

As discussed above, the Nominating and Governance Committee is charged with reviewing potential conflicts of interest and all Related Person Transactions. PPG and its subsidiaries purchase products and services from and/or sell products and services to companies of which certain of the directors, director nominees and/or executive officers of PPG are directors and/or executive officers. During 2016, PPG entered into the following transactions with Related Persons that are required to be reported under the rules of the Securities and Exchange Commission:

Stephen F. Angel, a director of PPG, is the Chairman, President and Chief Executive Officer of Praxair, Inc. During 2016, PPG and its subsidiaries purchased approximately $7.1 million of industrial gases from Praxair.

Martin H. Richenhagen, a director of PPG, is the Chairman, President and Chief Executive Officer of AGCO Corporation. During 2016, PPG and its subsidiaries sold approximately $2.9 million of coatings products to AGCO Corporation.

Michael W. Lamach, a director of PPG, is Chairman, President and Chief Executive Officer of Ingersoll-Rand plc. During 2016, PPG and its subsidiaries purchased approximately $200,000 of services from Ingersoll-Rand and sold approximately $4.2 million of coatings products to Ingersoll-Rand.

The Nominating and Governance Committee does not consider the amounts involved in such transactions material. Such purchases from and sales to each company involved less than 1% of the consolidated gross revenues for 2016 of each of the purchaser and the seller and all of such transactions were in the ordinary course of business.

Board Meetings and Committees

The Board currently has four standing committees: Audit Committee, Nominating and Governance Committee, Officers—Directors Compensation Committee and Technology and Environment Committee. Effective January 19, 2017, the membership of the Board's committees was realigned. The current composition of each Board committee is indicated below. The charter of each Board committee is available on the Corporate Governance section of our website at www.ppg.com/investor.

During 2016, the Board held ten meetings, the Audit Committee held five meetings, the Nominating and Governance Committee held seven meetings, the Officers—Directors Compensation Committee held five meetings, and the

​

Table of Contents

Technology and Environment Committee held two meetings. The average attendance at meetings of the Board and committees during 2016 was 96%, and no incumbent director attended less than 75% of the total number of meetings of the Board and committees on which such director served. PPG does not have a formal policy requiring attendance at the annual meeting of shareholders; however, all directors serving at the time of the 2016 annual meeting of shareholders other than Mr. Lamach attended the meeting.

Our independent directors meet separately, without any management present, at each meeting of the Board. The Board has designated the chair of the Nominating and Governance Committee to serve as the Lead Director and to preside over the independent director sessions. In their discretion, the independent directors may select another independent director to serve as the Lead Director.

Audit Committee

The Audit Committee is comprised of four directors, each of whom is independent under the standards adopted by the Board, the listing standards of the New York Stock Exchange and the applicable rules of the Securities and Exchange Commission. The committee's charter, which may be accessed on the Corporate Governance section of our website at www.ppg.com/investor, describes the composition, purposes and responsibilities of the committee. Among other things, the charter provides that the committee will be comprised of independent, non-employee directors. The functions of the committee are primarily to review with our independent auditors and our internal auditors their respective reports and recommendations concerning audit findings and the scope of and plans for their future audit programs and to review audits, annual and quarterly financial statements and accounting and financial controls. The committee also appoints our independent registered public accounting firm, oversees our internal auditing department, assists the Board in oversight of our compliance with legal and regulatory requirements related to financial reporting matters and oversees the risk management process. The Board has determined that each member of the committee is "financially literate" in accordance with the applicable rules of the New York Stock Exchange. In addition, the Board has determined that all of the members of the committee, including Mr. Richenhagen, the chair of the committee, are "audit committee financial experts" in accordance with the applicable rules of the Securities and Exchange Commission.

Audit Committee Report to Shareholders

The primary role of the Audit Committee is to oversee and review on behalf of the Board of Directors PPG's processes to provide for the reliability and integrity of the Company's financial reporting, including the Company's disclosure practices, risk management processes and internal controls. The Audit Committee operates under a written charter adopted by the Board of Directors.

The Audit Committee is responsible for the appointment of both the independent registered public accounting firm and PPG's lead internal auditor, the Director of Corporate Audit Services. In 2016, the Audit Committee approved the appointment of a new Director of Corporate Audit Services. In addition, the Audit Committee led the appointment and retention of PricewaterhouseCoopers LLP as PPG's independent registered public accounting firm for 2016 and participated in the selection process for a new lead audit partner due to the required rotation of PPG's current lead audit partner after completion of the 2017 audit. For the work performed on the 2016 audit, the Audit Committee discussed and evaluated PricewaterhouseCoopers' performance, which included an evaluation by the Company's management of PricewaterhouseCoopers' performance. The Audit Committee is responsible for the compensation of the independent registered public accounting firm and has reviewed and approved in advance all fees and services performed by PricewaterhouseCoopers.

The Audit Committee discussed with, and received regular status reports from the Director of Corporate Audit Services and PricewaterhouseCoopers on the overall scope and plans for their audits, their plans for evaluating the effectiveness of PPG's internal control over financial reporting and the coordination of efforts between them. The Audit Committee reviewed and discussed the key risk factors used in developing PPG's internal audit and PricewaterhouseCoopers' audit plans. The Audit Committee also reviewed with the Company's management PPG's risk management practices and an assessment of significant risks.

The Audit Committee met separately with both the Director of Corporate Audit Services and PricewaterhouseCoopers, with and without management present, to discuss the results of their examinations, their audits of PPG's financial statements and internal control over financial reporting and the overall quality of PPG's financial reporting. The Audit Committee also met separately with the Company's Executive Vice President and Chief Financial Officer and with the Company's Senior Vice President and General Counsel. The Audit Committee annually

reviews its performance and received feedback on its performance from the Company's management and PricewaterhouseCoopers.

The Company's management is responsible for the preparation and accuracy of PPG's financial statements. The Company is also responsible for establishing and maintaining adequate internal control over financial reporting. In 2016, PPG's independent registered public accounting firm, PricewaterhouseCoopers, was responsible for auditing the consolidated financial statements and expressing an opinion as to their conformity with generally accepted accounting principles, as well as expressing an opinion on the effectiveness of PPG's internal control over financial reporting.

In carrying out its responsibilities, the Audit Committee discussed and reviewed with the Company's management the process to assemble the financial statements, including the Company's internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations.

The Audit Committee reviewed and discussed the audited consolidated financial statements as of and for the year ended December 31, 2016 and management's report on internal control over financial reporting with management and with PricewaterhouseCoopers. The Audit Committee also discussed with PricewaterhouseCoopers the matters required by Auditing Standard No. 16, Communications with Audit Committees.

The Audit Committee has received the written independence disclosures and letter from PricewaterhouseCoopers required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence and discussed with PricewaterhouseCoopers its independence. In addition, the Audit Committee considered whether PricewaterhouseCoopers' provision of non-audit services to PPG is compatible with maintaining its independence.

Based upon these reviews and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the Securities and Exchange Commission.

Nominating and Governance Committee

The Nominating and Governance Committee is comprised of four directors, each of whom is independent under the standards adopted by the Board and the listing standards of the New York Stock Exchange. The committee's charter, which may be accessed on the Corporate Governance section of our website at www.ppg.com/investor, describes the composition, purposes and responsibilities of the committee. Among other things, the charter provides that the committee will be comprised of independent, non-employee directors. The charter also provides that the committee shall be responsible to identify and recommend to the Board of Directors persons to be nominated by the Board to stand for election as directors at each annual meeting of shareholders, the persons to be elected by the Board to fill any vacancy or vacancies in its number, and the persons to be elected by the Board to be Chairman of the Board, Vice Chairman of the Board, if any, President, if any, and the other executive officers of PPG. The committee also recommends to the Board actions to be taken regarding the structure, organization and functioning of the Board, and the persons to serve as members of the standing committees of, and other committees appointed by, the Board. The charter gives the committee the responsibility to develop and recommend corporate governance guidelines to the Board, and to recommend to the Board the process and criteria to be used in evaluating the performance of the Board and to oversee the evaluation of the Board.

Officers—Directors Compensation Committee

describes the composition, purposes and responsibilities of the committee. Among other things, the charter provides that the committee will be comprised of independent, non-employee directors.

Committee meetings are regularly attended by our Chairman and Chief Executive Officer and our Vice President of Human Resources, as well as a representative of the outside compensation consulting firm retained by the committee, Frederic W. Cook & Co., Inc. At each meeting, the committee meets in executive session. The committee's chair reports the committee's recommendations on executive compensation to the Board. The human resources department supports the committee in its duties and, along with the Compensation and Employee Benefits Committee, a committee comprised of members of senior management, may be delegated authority to fulfill certain administrative duties regarding our compensation programs. The committee has authority under its charter to retain, approve fees for and terminate advisors, consultants and agents as it deems necessary to assist in the fulfillment of its responsibilities.

The committee approves, adopts, administers, interprets, amends, suspends and terminates our compensation plans applicable to, and fixes the compensation and benefits of, all of our directors and executive officers. Recommendations regarding compensation of other officers are made by our Chairman and Chief Executive Officer. The conclusions reached and recommendations based on these reviews, including with respect to salary adjustments and annual award amounts, are presented to the committee. The committee can exercise its discretion in modifying any recommended adjustments or awards to executives. The committee regularly reviews tally sheets that set forth the Company's total compensation obligations to our senior executives under various scenarios, including retirement, voluntary and involuntary termination and termination in connection with a change in control of PPG.

The committee engaged Frederic W. Cook & Co., Inc. to advise the committee on all matters related to executive officer and director compensation. Specifically, Frederic W. Cook & Co. provides relevant market data, current updates regarding trends in executive and director compensation, and advice on program design, specific compensation decisions for the Chairman and Chief Executive Officer and on the recommendations being made by management for executives other than the Chairman and Chief Executive Officer. The committee meets independently with its consultant at each regularly scheduled meeting. All of the services that the compensation consultant performs for PPG are performed at the request of the committee, are related to executive and director compensation and are in support of decision making by the committee.

In 2016, the committee considered the independence of Frederic W. Cook & Co., Inc. in light of Securities and Exchange Commission rules and New York Stock Exchange listing standards. The committee requested and received a letter from Frederic W. Cook & Co. addressing Frederic W. Cook & Co.'s and the senior advisor involved in the engagement's independence, including the following factors: (1) other services provided to us by Frederic W. Cook & Co.; (2) fees paid by us as a percentage of Frederic W. Cook & Co.'s total revenue; (3) policies or procedures maintained by Frederic W. Cook & Co. that are designed to prevent a conflict of interest; (4) any business or personal relationships between the senior advisor and a member of the committee; (5) any company stock owned by Frederic W. Cook & Co. or the senior advisor; and (6) any business or personal relationships between our executive officers and Frederic W. Cook & Co. or the senior advisor. The committee discussed these considerations and concluded that the work performed by Frederic W. Cook & Co. and Frederic W. Cook & Co.'s senior advisor involved in the engagement did not raise any conflict of interest.

Compensation Program Design Mitigates Risk

Annually, PPG management undertakes a review of all of PPG's compensation programs to identify any inherent material risks to PPG created by these programs. Certain of these compensation programs are also reviewed by the Company's internal auditors. The framework used to identify any potential risks that could be incentivized by our compensation programs was developed with input from members of our human resources, finance, and legal functions and our independent executive compensation consultant, Frederic W. Cook & Co., Inc. Based on the results of the 2016 review, we concluded that the design of our compensation programs does not encourage our employees to take unnecessary or excessive risks that could harm the long-term value of PPG. Features of our compensation programs and practices that mitigate risk include, among other things: (i) incentive plans that are appropriately weighted between short-term and long-term performance and cash and equity; (ii) long-term incentives that consist of a mix of stock options, performance-based restricted stock units and total shareholder return contingent shares, which provides for a balanced mix of performance measures; (iii) ranges of performance and multiple performance targets are utilized to determine incentive compensation payouts, rather than a single performance target that provides an "all or nothing" basis for compensation; (iv) maximum payouts are in place in our incentive compensation programs to limit excessive payments; (v) determination of incentive compensation payouts is subject to managerial approval and/or Officers—Directors Compensation Committee discretion; and (vi) our executive officers are subject to a recoupment policy in the event of a financial restatement affecting their incentive compensation payout.

Compensation Committee Interlocks and Insider Participation

No member of the Officers—Directors Compensation Committee was at any time during 2016 an officer or employee of PPG or any of our subsidiaries nor is any such person a former officer of PPG or any of our subsidiaries. In addition, no "compensation committee interlocks" existed during 2016. For information concerning Related Person Transactions involving members of the Officers—Directors Compensation Committee, see "Corporate Governance—Certain Relationships and Related Transactions" on page 14.

Technology and Environment Committee

The Technology and Environment Committee is comprised of five directors, each of whom is independent under the standards adopted by the Board. The committee's charter, which may be accessed on the Corporate Governance section of our website at www.ppg.com/investor, describes the composition, purposes and responsibilities of the committee. The primary purpose of the committee is to discharge certain of the Board's responsibilities relating to the oversight of programs, initiatives and activities of PPG in the areas of science, technology and sustainability. The functions of the committee are primarily to assess the science and technology capabilities of PPG in all phases of its activities in relation to its corporate strategies and plans; review with management the existing and emerging technologies, and environment, health, safety, product stewardship and other sustainability issues, that can have a material impact on PPG; and review the status of our environment, health, safety, product stewardship and other sustainability policies, programs and practices.

Shareholder Recommendations or Nominations for Director

The Nominating and Governance Committee is responsible for identifying and screening potential director candidates and for recommending to the Board qualified candidates for nomination. The committee considers recommendations of potential candidates from current directors, management and shareholders. The committee also has authority to retain and terminate search firms to assist in identifying director candidates. From time to time, search firms have been paid a fee to identify candidates. In July 2016, the Board of Directors elected Ms. Healey as a director of PPG. She was initially identified as a potential nominee by a third party search firm engaged by the Nominating and Governance Committee and, following an interview process undertaken by Mr. McGarry, Mr. Grant and other directors and a review of her candidacy by the Nominating and Governance Committee, Ms. Healey was recommended by the Nominating and Governance Committee as a nominee for election to the Board.

candidates for director should have knowledge of the global operations of industrial businesses such as those of PPG;

•

candidates for director should be cognizant of PPG's societal responsibilities in conducting its operations;

•

each candidate should have sufficient time available to be a meaningful participant in Board affairs. Candidates should not be considered if there is either a legal impediment to service or a foreseeable conflict of interest which might materially hamper full and objective participation in all matters considered by the Board of Directors;

•

absent unforeseen health problems, each candidate should be able to serve as director for a sufficient period of time to make a meaningful contribution to the Board's guidance of PPG's affairs; and

•

the Board will be comprised of a majority of independent directors.

In applying these criteria, the committee seeks to establish a Board that, when taken as a whole, should:

•

be representative of the broad scope of shareholder interests, without orientation to any particular constituencies;

•

challenge management, in a constructive way, to reach PPG's goals and objectives;

•

be sensitive to the cultural and geographical diversity of shareholders, associates, operations and interests;

•

be comprised principally of active or retired senior executives of publicly held corporations or financial institutions, with consideration given to those individuals who are scientifically-oriented, educators and government officials having corporate experience, whenever the needs of PPG indicate such membership would be appropriate;

•

include directors of varying ages, but whose overriding credentials reflect maturity, experience, insight and prominence in the community; and

•

be small enough to promote open and meaningful boardroom discussion, but large enough to staff the necessary Board committees.

The Nominating and Governance Committee does not a have formal policy with regard to the consideration of diversity in identifying director candidates. However, as discussed above, we endeavor to have a Board representing diverse experience at policy-making levels in business, government, education and technology, and in areas that are relevant to the Company's global activities. The Nominating and Governance Committee seeks to find director candidates who have demonstrated executive leadership ability and who are representative of the broad scope of shareholder interests by identifying candidates from diverse industries having diverse cultural backgrounds, ethnic backgrounds, viewpoints and ages. The Nominating and Governance Committee believes that the current members of the Board provide this diversity.

Process.    Shareholders wishing to recommend or nominate a nominee for director should send their recommendation or nomination to the chairman of the Nominating and Governance Committee of the Board of Directors, in care of our corporate secretary at PPG Industries, Inc., One PPG Place, Pittsburgh, Pennsylvania 15272. PPG's Bylaws provide for "proxy access." Proxy access is a process that allows an eligible shareholder or a group of eligible shareholders to nominate director candidates to appear in PPG's proxy materials. Proxy access is available to shareholders or groups consisting of no more than 20 shareholders that have held at least 3% of PPG's outstanding stock for at least three years and who have met the other requirements set forth in Article I of PPG's Bylaws. A shareholder recommendation or nomination of a director candidate must be submitted by the deadlines and with the information and written representations that are described in Article I of our Bylaws. Director nominations submitted pursuant to PPG's proxy access Bylaw for consideration at the 2018 annual meeting of shareholders must be received by PPG no earlier than October 10, 2017 and no later than November 9, 2017. A copy of PPG's Bylaws may be accessed on the Corporate Governance section of our website at www.ppg.com/investor.

Director Resignation Policy

Our Bylaws provide that if an incumbent director is not elected by majority vote in an "uncontested election" (where the number of nominees does not exceed the number of directors to be elected), the director must offer to tender his or her resignation to our Board of Directors. The Nominating and Governance Committee would then make a recommendation to the Board whether to accept or reject the resignation, or whether other action should be taken. The Board will act on the Nominating and Governance Committee's recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date the election results are certified. The director who tenders his or her resignation will not participate in the Board's decision with respect to their resignation. The election of directors that will be held at the 2017 Annual Meeting is an uncontested election.

Codes of Ethics

Our Global Code of Ethics, which was updated in 2017, is applicable to all directors and employees worldwide, embodies our global principles and practices relating to the ethical conduct of our business and our long-standing commitment to honesty, fair dealing and compliance with all laws affecting our business. We also have a Code of Ethics for Senior Financial Officers that is applicable to our principal executive officer, principal financial officer, principal accounting officer, controller or persons performing similar functions. The Global Code of Ethics and Code of Ethics for Senior Financial Officers are available on the Corporate Governance section of our website at www.ppg.com/investor. In addition, we intend to post on our website all disclosures that are required by law, the Form 8-K rules or the New York Stock Exchange listing standards concerning any amendments to, or waivers from, any provision of our codes.

The Board has established a means for employees, customers, suppliers, shareholders or other interested parties to submit confidential and anonymous reports of suspected or actual violations of our Global Code of Ethics. Any employee, shareholder or other interested party can call the PPG Ethics HELPLINE toll-free to submit a report. In North America, this number is (800) 461-9330. This number is operational 24 hours a day, seven days a week. PPG Ethics HELPLINE numbers for other regions may be found on the Ethics page of our website at www.ppg.com/ethics.

Communications with the Board

Shareholders and other interested parties may send communications to the Board, the independent directors (individually or as a group) or the Lead Director in writing by sending them in care of our corporate secretary at PPG Industries, Inc., One PPG Place, Pittsburgh, Pennsylvania 15272. All communications received will be opened by the corporate secretary for the sole purpose of determining whether the contents represent a message to directors. Communications deemed by the corporate secretary to be frivolous or otherwise inappropriate for the Board's consideration will not be forwarded. The corporate secretary will maintain a log of all such communications. Communications of an urgent nature are promptly reported to the Board. Communications to directors may also be forwarded within PPG for review by a subject matter expert.

COMPENSATION OF DIRECTORS

Overview

The compensation program for the directors who are not also officers of PPG, to whom we refer as non-employee directors, is reviewed annually by the Officers—Directors Compensation Committee to ensure that the program remains competitive. As a part of the committee's review, the types and levels of compensation offered to our non-employee directors are compared with those provided by a select group of comparable companies. The companies comprising this comparator group are used for review of the executive officer compensation program as well and are:

Taking into consideration the size of PPG relative to this comparator group and advice from Frederic W. Cook & Co., Inc., the committee reports its recommendations to the Board for approval. The committee does not determine director compensation, but only makes recommendations to the Board. Changes to the non-employee directors' compensation program generally become effective as of the year following adoption.

Annual Retainer

For 2016, each of our non-employee directors received an annual retainer with a value equal to $270,000, of which $135,000 was paid in cash and $135,000 in equity in the form of time-based restricted stock units, or TBRSUs. The cash portion of the retainer was payable in quarterly installments, with the first quarterly installment paid after the annual shareholders meeting. The number of TBRSUs a director received was determined by dividing $135,000 by the weighted average closing price of our stock on the grant date, which was the date of the 2016 annual meeting of shareholders. A TBRSU represents the right to receive a share of PPG common stock upon vesting and earns dividend equivalents during the vesting period when dividends are declared on PPG common stock, but does not carry voting rights or other rights afforded to a holder of PPG common stock. TBRSUs granted in 2016 vest on the day prior to the 2017 Annual Meeting of Shareholders. TBRSUs granted in 2013 vested in 2016, three years after the date of grant.

Additional Retainers for Committee Chairs

In addition to the annual retainer for each non-employee director, each non-employee director who chairs a Board standing committee is entitled to an additional annual cash retainer, which is payable at the same time as the regular annual retainer. For 2016, the additional annual retainer for service as a committee chair was:

Insurance Coverage

We pay the premiums to provide each of our non-employee directors with the following insurance coverage:

•

Accidental death and dismemberment insurance coverage, which provides $250,000 for accidental loss of life, and up to 100% of the death benefit for loss of limb. The aggregate cost to PPG of providing this coverage to non-employee directors for 2016 was $2,387; and

•

PPG aircraft travel insurance coverage, which provides up to a $1,000,000 per seat voluntary settlement allowance, for travel on a PPG-owned aircraft, and a reduced amount for travel on a PPG leased or chartered aircraft. The aggregate cost to PPG of providing this coverage to non-employee directors for 2016 was $17,105.

Deferred Compensation

A non-employee director may elect to have all or a portion of his or her retainer fees (including fees payable in TBRSUs) credited to the PPG Industries, Inc. Deferred Compensation Plan for Directors, thus deferring receipt of such fees until after the director leaves the Board. All amounts held in a director's account under the Deferred Compensation Plan are credited as hypothetical shares of our stock, or what we refer to as common stock equivalents, the number of which is determined by dividing the dollar amount of the deferral by the closing stock price of PPG common stock on the New York Stock Exchange on the date of the deferral. Common stock equivalents earn dividend equivalents (that are converted into additional common stock equivalents) when dividends are declared on PPG common stock, but do not carry voting rights or other rights afforded to a holder of PPG common stock. Each non-employee director will generally be paid his or her deferred compensation account balance no earlier than six months and ten days after leaving the Board of Directors, except in circumstances of death or disability, in which case payment shall be made as soon as administratively possible. Each non-employee director's

account balance related to compensation deferred on or after January 1, 2005 will be paid in a lump sum; however, a non-employee director may elect to receive payment of his or her account balance related to compensation deferred prior to January 1, 2005 in one to fifteen annual installments. All distributions are made in the form of one share of PPG common stock for each common stock equivalent credited to the director's deferred account (and cash as to any fractional common stock equivalents).

Charitable Awards Program

As part of our overall program to promote charitable giving, we established a directors' charitable award program funded by insurance policies on the lives of directors who were initially elected before July 17, 2003. Upon the death of any of these directors, PPG will donate an amount up to and including a total of $1 million to one or more qualifying charitable organizations designated by any such director and approved by PPG. We will be reimbursed subsequently from the proceeds of the life insurance policies. Directors derive no financial benefit from this program since all charitable deductions accrue solely to PPG. This program is not applicable to any director initially elected on or after July 17, 2003. The aggregate cost of this program to PPG for 2016 was $59,627.

In addition to the above program, all of our current directors are eligible to participate in the PPG Industries Foundation Matching Gifts Program, which encourages charitable donations by our directors by matching his or her contributions to eligible institutions. Contributions of up to a total of $10,000 per year may be matched under the program. Most charitable organizations are eligible for the Matching Gifts Program, with a few exceptions.

Stock Ownership

We established stock ownership guidelines for all non-employee directors effective January 1, 2005. Under the guidelines, each non-employee director is required to own shares of our stock with a value equal to five times the portion of the annual retainer that is paid in cash. For non-employee directors, unvested TBRSUs and common stock equivalent shares credited to the director under the Deferred Compensation Plan are counted toward meeting this requirement. Mr. Lamach and Ms. Healey are within their five-year compliance period and should meet the ownership requirement by the end of such period. All other non-employee directors have met or exceeded the ownership requirement.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

PPG's vision is to be the world's leading coatings company by consistently delivering high-quality, innovative and sustainable solutions that customers trust to protect and beautify their products and surroundings. This vision is enabled by a strategy of accelerated profitable growth and enhanced operational excellence. Our executive compensation program is a key factor in promoting this strategy and a crucial tool in aligning the interests of our senior leadership with those of our shareholders.

The Company's strong performance and focus on shareholder value is evident in our continuing legacy of outstanding cash generation and rewarding shareholders. PPG has paid uninterrupted annual dividends since 1899 and has increased its annual dividend payout for 45 consecutive years. Continuing with that legacy, in 2016 PPG returned about 78% of cash from operating activities - continuing operations, excluding cash paid to fund the Pittsburgh Corning asbestos trust, to shareholders in the form of an increased annual per share dividend payout and share repurchases.

Executive compensation is based on our pay-for-performance philosophy, which emphasizes executive performance measures that correlate closely with the achievement of both shorter-term performance objectives and longer-term shareholder value creation. To this end, a substantial portion of our executives' annual and long-term compensation is performance-based, with the payment being contingent on the achievement of performance goals. We believe the program strikes the appropriate balance between effectively incentivizing our executives based on performance and utilizing responsible, market competitive pay practices in order that our executives dedicate themselves fully to value creation for our shareholders. This balance is evidenced by the following:

•

In 2016, the Company delivered strong financial performance through a sharp focus on cost management and sales volume growth and despite the persistent, unfavorable impact of weaker foreign currencies and modest and uneven global economic growth. Total net sales from continuing operations for 2016 were consistent with 2015, despite unfavorable currency translation of 3%. The Company's 2016 full-year reported net income from continuing operations was $564 million, or $2.11 per diluted share, versus $1.34 billion, or $4.89 per diluted share, in 2015. Adjusted net income from continuing operations for 2016 was $1.55 billion, versus $1.49 billion in 2015. Full-year adjusted earnings-per-diluted share from continuing operations was $5.82, up 7% year-over-year.

•

In April, the Company raised the per-share dividend by 11%—paying approximately $415 million in dividends in 2016. The Company also repurchased approximately $1.05 billion of stock in 2016.

•

In 2016, the Company completed several acquisitions, increasing both geographic and product scope. In addition, the Company divested several businesses, including the flat glass business, the European fiber glass business and the Company's ownership interests in two Asian fiber glass joint ventures.

The following charts contain adjusted earnings-per-diluted share from continuing operations, net sales from continuing operations and adjusted net income from continuing operations for each of the last five fiscal years:

Adjusted earnings-per-diluted share from continuing operations and adjusted net income from continuing operations are not recognized financial measures determined in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and should not be considered a substitute for earnings-per-diluted share or net income or other financial measures as computed in accordance with U.S. GAAP. PPG's management considers this information

useful in providing insight into the company's ongoing operating performance because it excludes the impact of items that cannot reasonably be expected to recur on a quarterly basis or that are not attributable to our primary operations. A Regulation G reconciliation of adjusted earnings-per-share from continuing operations and adjusted net income from continuing operations to reported adjusted earnings-per-diluted share from continuing operations and net income from continuing operations is included in Annex A to this Proxy Statement.

•

Consistent with our performance in 2016, annual incentive awards were paid to executive officers ranging from 126% to 159% of target. Our total shareholder return over the past three years when measured against the S&P 500 was in the 36th percentile resulting in the payment of long-term TSR share awards at 42.9% of target.

•

Between 65% and 89% of the named executive officers' target total direct compensation opportunity for 2016 was in the form of performance-based variable compensation and long-term incentives motivating them to deliver strong business performance and create shareholder value.

•

Base salary and annual incentive targets for our executive officers are established annually to maintain parity with the competitive market for executives in comparable positions. Target total annual compensation for each position is set at or near the market median.

•

PPG's compensation programs are reviewed annually to identify any inherent material risks to PPG created by these programs. Based on the results of the 2016 review, we concluded that the design of our compensation programs does not encourage our employees to take unnecessary or excessive risks that could harm the long-term value of PPG.

•

At the 2016 annual meeting, we held a shareholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our shareholders overwhelmingly approved the compensation of our named executive officers, with approximately 97% of shareholder votes cast in favor of our 2016 say-on-pay resolution. Following its review of this vote, the Officers—Directors Compensation Committee recommended to the full Board that we retain our general approach to executive compensation, with an emphasis on short- and long-term incentive compensation that rewards our executive officers when they deliver value for our shareholders. Consistent with this philosophy:

•

Our performance metrics are focused on increasing shareholder value and are tied to measures impacting both shorter-term and longer-term performance. Shorter-term performance metrics include adjusted earnings-per-diluted share from continuing operations, cash flow from operating activities-continuing operations, pre-tax, pre-interest income, working capital reduction, and sales volume/mix growth. Longer-term performance metrics include total shareholder return, adjusted earnings-per-diluted share growth, cash flow return on capital and stock price appreciation.

•

Payment of long-term incentive awards is based solely on Company performance. We have three-year award and payout cycles for both performance-based restricted stock units, or PBRSUs, and total shareholder return shares, or TSR shares. We also have three-year vesting for stock options.

•

We provide very limited perquisites to our executive officers.

Our officers are subject to stock ownership requirements. Our Chief Executive Officer must own shares of PPG common stock with a value of six times his base salary, and the other executive officers must own shares of PPG common stock with a value of three times his or her salary. Officers are expected to meet these ownership requirements within five years of election. Those officers who have not yet met this requirement are paid 20% of their annual incentive in PPG stock, which is restricted from sale for a period of two to five years. In addition, for officers who have been subject to the policy for more than five years at their current requirement level and have not met the ownership requirement, 100% of the vested shares delivered from the PBRSU award and TSR share award must be held by the officer for a minimum of one year and until the requirement is met. All executive officers named in the Summary Compensation Table have met their ownership requirement, except for Mr. Sklarsky who was within his five-year compliance period at the time of his retirement.

•

Our officers may not engage in transactions that are contrary to the interests of shareholders, such as "short sales," "short sales against the box," "put" and "call" options and hedging transactions designed to minimize an executive's risk inherent in owning PPG stock. In addition, officers may not hold PPG stock in a margin account and may not pledge PPG stock as collateral for a loan.

•

Executive officers are subject to a "clawback" policy that is designed to recoup incentive compensation when a financial restatement occurs and certain other conditions exist.

We do not provide tax gross-ups on perquisites to our named executive officers.

Compensation Philosophy and Objectives

PPG's philosophy in establishing compensation policies for our executive officers is to align compensation with our strategic objectives, while concurrently providing competitive compensation that enables us to attract and retain top-quality executive talent. The primary objectives of our compensation policies for executive officers are to:

•

Attract and retain executive officers by offering total compensation that is competitive with that offered by similarly situated companies and rewarding outstanding personal performance;

•

Promote and reward the achievement of short-term objectives that our Board of Directors and management believe will lead to long-term growth in shareholder value; and

•

Closely align the interests of executive officers with those of our shareholders by making long-term incentive compensation dependent upon the Company's financial performance and total shareholder return.

Principal Components of Executive Compensation

The principal components of our executive compensation program are:

Mix of Compensation Components

Executive compensation is based on our pay-for-performance philosophy, which emphasizes executive performance measures that correlate closely with the achievement of both shorter-term performance objectives and longer-term shareholder value creation. To this end, a substantial portion of our executives' annual and long-term compensation is performance-based, with the payment being contingent on the achievement of performance goals. The portion of compensation that is performance-based increases with the executive's level of responsibility. We use performance-based compensation for more senior positions because these roles have greater leadership responsibility and influence on the performance of the Company as a whole.

Compensation Program Design Mitigates Risk

In 2016, the Company's management undertook a review of all of PPG's compensation programs to identify any inherent material risks to PPG created by these programs. Based on the results of this review, we concluded that the design of our compensation programs does not encourage our employees to take unnecessary or excessive risks that could harm the long-term value of PPG. For more information about this review and the features of our compensation program that mitigate risk, see "Corporate Governance—Compensation Program Design Mitigates Risk" on page 18.

Annual Compensation Programs

Our executive officers receive two forms of annual compensation—base salary and annual incentive awards—which together constitute an executive's total annual compensation. Please note that "total annual compensation," as discussed in this Compensation Discussion and Analysis, differs from the "Total" compensation column of the Summary Compensation Table on page 40, which includes long-term incentive and other forms of compensation. The levels of base salary and annual incentive targets for our executive officers are established annually under a

​ ​

program intended to maintain parity with the competitive market for executives in comparable positions. Target total annual compensation for each position is set at or near the "market value" for that position.

To determine market value, the compensation committee considers compensation data based on a comparator group, as well as the most recently available data from nationally-recognized independent executive compensation surveys representing a cross section of manufacturing companies.

For purposes of establishing the 2016 executive compensation program, the compensation committee considered a competitive analysis of total direct compensation levels and compensation mixes for our executive officers, using information from:

•

two general industry surveys as provided by management: the Aon Hewitt Associates 2015 TCM Executive Total Compensation Survey and the Willis Towers Watson 2015 U.S. General Industry Executive Database. The competitive consensus for top five named executive officers consists of an equally-weighted average of median data from both general industry surveys; and

•

comparison company median data from a comparator group consisting of the following 20 companies:

Our comparator group is intended to be representative of the market in which we compete most directly for executive talent. The selection of companies comprising our comparator group is based on similarity in revenue size, lines of business, participation in global markets and market capitalization.

The compensation committee regularly reviews this group of companies with our independent executive compensation consultant, Frederic W. Cook & Co., Inc., to ensure that it remains an appropriate benchmark for us.

We target the median levels of compensation to derive our market value by adjusting this compensation data to reflect differences in company revenues using regression analysis. The general industry data and the comparator group data are blended when composing the competitive analysis, when possible, such that the combined general industry data and the comparator group are each weighted 50%. The competitive analysis showed that the Company's named executive officers' 2016 target total direct compensation was positioned in a range around the median of the compensation of the executives comprising the competitive analysis, and none of our named executive officers' target total direct compensation was above the range around the median for their peers in the competitive analysis.

In addition, the compensation committee annually reviews a tally sheet of each executive officer's compensation. Each tally sheet includes detailed data for each of the following compensation elements:

•

Annual compensation: Information regarding base salary and annual incentive targets for the current year;

•

Long-term incentive awards: Information regarding all equity-based awards, whether vested or unvested, including total pre-tax value to the executive and holdings relative to our stock ownership requirements;

•

Benefits and perquisites: Line item summary showing the annualized cost to the Company of health and welfare benefits, life insurance and perquisites;

•

Pension and deferred compensation: Annualized cost to the Company of pension plan benefits (qualified plan and non-qualified plan) and defined contribution plans (401(k) and deferred compensation); and

•

Description and quantification of all compensation and benefits payable upon retirement, termination of employment or change in control.

​

Table of Contents

The compensation committee reviews the information presented in the tally sheet to ensure that it is informed of the compensation and benefits each executive is receiving annually.

The charts below illustrate the allocation of the principal compensation components for our named executive officers for 2016.

Annual Compensation Policies

Our annual compensation policies reflect our pay-for-performance philosophy. We set target total annual compensation for our executive officers to be competitive with the market value for comparable positions, taking into account each executive's experience in the position and performance. Annual incentive awards are targeted at a level that, when combined with base salaries, is intended to yield total annual compensation that approximates market value. As a result, total annual compensation for a position generally should exceed its market value when our financial performance exceeds our applicable annual targets and individual performance contributes to meeting our objectives. Total annual compensation generally should be below market value when our financial performance does not meet targets and/or individual performance does not have a favorable impact on our objectives.

Base Salary.    Based on the compensation committee's review of the applicable compensation data as discussed above, in February 2016 the committee set base salaries effective March 1, 2016 for all executive officers in relation to the market value for comparable positions. Mr. McGarry received a base salary increase of $100,000; Messrs. Sklarsky, Sekmakas and Bost each received a base salary increase of $20,000; and Mr. Knavish received a base salary increase of $70,000.

Mr. Bunch retired as Executive Chairman on September 1, 2016. His base salary, paid for eight months of active employment, remained unchanged from 2015.

With his promotion to Chairman and Chief Executive Officer on September 1, 2016, Mr. McGarry's annual base salary was increased to $1,150,000.

Annual Incentive Awards.    In February 2016, the compensation committee determined that the incentive goal for 2016 annual incentive awards to executive officers would be based upon adjusted consolidated income from continuing operations on a pre-tax basis, excluding noncontrolling interests, for the year ended December 31, 2016. Consolidated income is determined in accordance with generally accepted accounting principles, as reflected in our audited consolidated statement of income, and includes any non-operating adjustments approved by the committee. The committee has established guidelines for certain types of non-operating adjustments used by the committee in determining adjusted consolidated earnings for these purposes. These adjustments generally relate to legacy litigation or legacy environmental remediation, accounting rule changes and major portfolio changes, including planned restructuring initiatives. The committee also established that the maximum annual incentive award that could

​

​

---

Table of Contents

be paid to our Chairman and Chief Executive Officer and our retired Executive Chairman would be equal to 0.75% of adjusted consolidated income and the maximum annual incentive award that could be paid to each of the other executive officers named in Summary Compensation Table would be equal to 0.5% of adjusted consolidated income. In no case may an executive officer named in the Summary Compensation Table be granted an annual incentive award that exceeds $6 million. Final awards for the executive officers named in the Summary Compensation Table are subject to the negative discretion of the compensation committee.

Although the percentage of adjusted consolidated income allocated to each executive officer determines the maximum amount that can be paid individually, the compensation committee's practice has been to approve annual incentive awards based primarily on target levels set for each executive officer and pre-established, short-term performance objectives. Thus, on an annual basis, the committee establishes a target annual incentive award for each executive officer based on the executive's position and the market value of comparable positions in our comparator group. For 2016, this target, when expressed as a percentage of base salary, was as follows for each of the executive officers named in the Summary Compensation Table: Mr. McGarry, 140%; Mr. Bunch, 140%; Mr. Sklarsky, 90%; Mr. Sekmakas, 90%; Mr. Bost, 85%; and Mr. Knavish, 70%.

The amount of an executive's actual annual incentive award, in relation to the executive's target opportunity, is determined on the basis of achievement of short-term performance objectives. The performance objectives for our Chairman and Chief Executive Officer, our retired Executive Chairman, our Chief Financial Officer and our Senior Vice President and General Counsel include specific financial targets for Company performance (weighted 70%) and personal performance (weighted 30%). The performance objectives for our other executive officers include specific financial targets for Company performance (weighted 20%), business performance (weighted 50%) and personal performance (weighted 30%).

For many years, PPG has been committed to sustainability. Recognizing the importance of sustainability and its ability to drive innovation in our business, PPG includes sustainability goals in the performance goals of its Chairman and Chief Executive Officer and our retired Executive Chairman. Performance against these goals is reviewed by the Officers—Directors Compensation Committee of the Board of Directors. Safety, waste costs, energy usage and costs, and sustainable product sales are part of these executives' annual performance review.

Annual incentive compensation of PPG's executives and senior managers is partially (30 percent) based on personal goals that tie to overall corporate business goals, with the remainder based on company and business financial performance. PPG does not require that its executives have personal goals linked to social or environmental performance, although some executives, by virtue of their responsibilities, may have goals related to those issues. In addition, executive business unit leaders receive sustainability scorecards for their business unit, and they are responsible for driving improvement in their business unit's sustainability metrics.

The potential payout of the Company performance component of the annual incentive is based on a pre-determined schedule recommended by management and approved by the compensation committee. The schedule corresponds to various levels of potential Company financial performance measured by adjusted earnings-per-diluted share from continuing operations (weighted 70%), adjusted cash flow from operating activities (weighted 20%) and sales volume/mix growth (weighted 10%), assuming the minimum adjusted earnings-per-diluted share from continuing operations threshold is met. The maximum payout of this component under the schedule is 220% of target.

In assessing Company performance against objectives, the compensation committee considers actual results against the approved target objectives, considering whether significant unforeseen obstacles or favorable circumstances altered the expected difficulty of achieving the desired results and the extent to which economic assumptions underlying the performance targets materialized. The overall assessment for Company performance then determines the percentage of the target award that will be paid to each executive for the Company performance component of the annual incentive award. For 2016, as described below, the committee exercised discretion in applying certain non-operating adjustments to the actual earnings-per-diluted share from continuing operations and cash flow from operating activities – continuing operations results, consistent with guidelines established previously by the committee.

In February 2016, the compensation committee approved a financial performance standard for the Company component of the award of $6.16 adjusted earnings-per-diluted share from continuing operations, adjusted cash flow from operating activities of $2,198 million and sales volume/mix growth of 2.5%. If achieved, this standard would generate 124% of the target bonus for the Company component of the award. The compensation committee increased the award that would be received if these standards were met to 124% due to the ambitious nature of the Company's plan versus expected, continued foreign currency headwinds and persistent slow growth in certain major global economies and end-use markets. The approved performance standard for 2016 included a threshold adjusted

​

earnings-per-diluted share from continuing operations of $4.60, below which no bonus would be paid, regardless of either the adjusted cash flow from operating activities or the sales volume/mix growth performance, and a minimum cash flow from continuing operations performance of $1,368 million and a minimum sales growth/mix growth performance of 0.0% for payment on those two components. In addition, the approved performance standard for 2016 included a maximum bonus opportunity of 220% if adjusted earnings-per-diluted share from continuing operations of $6.60, adjusted cash flow from operating activities of $2,462 million and sales volume/mix growth of 4.0% were achieved.

In December 2016, after considering the revised 2016 Company performance plan presented by management to reflect the sale of the flat glass business in October 2016, the compensation committee revised the predetermined Company financial performance standard to adjusted earnings-per-diluted share from continuing operations of $6.07 (from $6.16) and adjusted cash flow from operating activities of $2,160 million (from $2,198 million). If achieved, this standard would generate 124% of the target bonus for the Company component of the award. The revised performance standard included a threshold adjusted earnings-per-diluted share from continuing operations of $4.51, below which no bonus would be paid, regardless of the cash flow from operating activities or the sales volume/mix growth performance, and a minimum cash flow from continuing operations of $1,330 million for payment on that component.

In February 2017, the compensation committee reviewed adjusted earnings-per-diluted share from continuing operations of $5.99, adjusted cash flow from operating activities of $2,237 million and sales volume/mix growth of 1.0%. The committee approved the Company performance component for incentive awards based on adjusted earnings-per-diluted share from continuing operations of $5.99, adjusted cash flow from operating activities of $2,237 million and sales volume/mix growth of 1.0%. The earnings-per-diluted share performance component included adjustments of $2.31 for pension settlement charges, $0.57 for the net tax effect of asbestos settlement trust funding, $0.55 for a business restructuring charge, $0.20 for an environmental remediation charge, $0.17 for a loss on the divestiture of European fiber glass business, $0.17 for nine months of flat glass business results, $0.04 for an asset write-down, $0.03 for transaction-related costs, $0.02 for a debt refinancing charge offset by $0.18 gain on disposals of ownership interests in business affiliates. Adjustments to the cash flow from operating activities performance component included adding back $630 million for the net tax effect of asbestos settlement trust funding, $204 million for cash contributions to pension plans and $78 million for restructuring cash spending.

Adjusted earnings-per-diluted share from continuing operations of $5.99, adjusted cash flow from operating activities of $2,237 million and sales volume/mix growth of 1.0% resulted in a payout of 119% of target for the Company performance component, based on the schedule discussed above. For the adjusted earnings-per-diluted share component, this schedule yielded a payout of 123% for the result of $5.99 per share. For the adjusted cash flow component, this schedule yielded a payout of 135% for the above target result of $2,237 million. For the sales volume/mix growth component, this schedule yielded a payout of 60% for the result of 1.0%. Combining these three results using the 70%, 20% and 10% weightings, respectively, yielded an overall result of 119%, which was approved by the compensation committee.

Approved 2016 Performance Components

Table of Contents

The personal performance component of the annual incentive is based on measures of individual performance relevant to the particular individual's job responsibilities. The personal performance assessment of our Chairman and Chief Executive Officer and our retired Executive Chairman is determined by the compensation committee, with input from the other non-management members of the Board. The personal performance of each other executive officer is determined by our Chairman and Chief Executive Officer. The following factors were considered in assessing the personal performance of the executive officers named in the Summary Compensation Table for 2016 against individual objectives:

This is the first year under the leadership of Mr. McGarry as he transitioned into his role of Chairman and Chief Executive Officer. Mr. McGarry was supported by Mr. Bunch until his retirement as Executive Chairman on September 1, 2016. The Company delivered strong financial performance through sharp focus on cost management and sales volume growth and despite the persistent, unfavorable impact of weaker foreign currencies and modest and uneven global economic growth. Continued strong cash generation supported PPG's cash deployment commitments and growth opportunities. The Company completed several acquisitions, increasing both geographic and product scope. In addition, the Company divested several businesses, including the flat glass business, the European fiber glass business and the Company's ownership interests in two Asian fiber glass joint ventures. Total net sales from continuing operations for 2016 were consistent with 2015, despite unfavorable currency translation of 3%. The Company also made great progress on a number of sustainability initiatives, including lower energy consumption and a reduction in hazardous waste disposal costs. Full-year adjusted earnings-per-diluted share from continuing operations was $5.82, up 7% year over year. The 2016 Company results exceeded expectations for Messrs. McGarry and Bunch.

Mr. Sklarsky's leadership of the finance organization through a number of key strategic initiatives, including the completion of the annuitization of a large portion of U.S. and Canadian pension obligations, the completion of a debt refinancing project and fully funding the Pittsburgh Corning asbestos trust. In addition, he provided guidance over the completion of several acquisitions and divestitures, including the flat glass business, the European fiber glass business and the Company's ownership interests in two Asian fiber glass joint ventures. Mr. Sklarsky effectively performed as a member of the Executive Committee, positively influencing the results of the Company. These results exceeded expectations.

Mr. Sekmakas led the industrial and packaging coatings businesses, the specialty coatings and materials business and the flat glass and fiber glass businesses. Under Mr. Sekmakas' leadership, the industrial coatings business delivered solid sales volume growth driven by strong end-use market demand for automotive components, electronics materials, and coil and extrusion coatings products. The packaging coatings business delivered increased sales volume growth across all regions, with the Company's new interior can coatings technologies continuing to drive sales volume growth. He also provided leadership to the corporate purchasing organization. He successfully completed the dispositions of the Company's non-core flat glass and European fiber glass businesses. Mr. Sekmakas effectively performed as a member of the Executive Committee, positively influencing the results of the Company. These results exceeded expectations.

Mr. Bost led the legal organization and was instrumental in successfully completing a number of acquisitions during the year as well as the dispositions of the Company's flat glass business, the European fiber glass business and the Company's ownership interests in two Asian fiber glass joint ventures. In addition, he provided leadership throughout the process of fully funding the Pittsburgh Corning asbestos trust. Mr. Bost effectively performed as a member of the Executive Committee, positively influencing the results of the Company. These results exceeded expectations.

Mr. Knavish primarily led the automotive original equipment manufacturer (OEM) business and the Latin America region. Under Mr. Knavish's leadership, growth continued in the automotive OEM business aided by the continued strength in Europe and Asia Pacific. He also provided leadership to the environmental, health and safety (EHS) organization. These results exceeded expectations.

Business unit short-term performance objectives and their assessment are specific to each particular business and are based on pre-tax, pre-interest earnings, working capital reduction, and sales volume/mix growth. The overall assessment of business performance determines the percent of target paid to applicable executives for the business component of the annual incentive award.

For 2016, we assessed the performance of 13 defined businesses against the criteria discussed above. Actual payouts of the business performance component ranged from 20% to 190% of target. The business performance component payouts for two of our executive officers named in the Summary Compensation Table, Messrs. Sekmakas and Knavish, are based on the performance of each of the specific businesses and regions for which each of them is responsible.

Table of Contents

Mr. Sekmakas' business performance component was a composite of the results of the industrial and packaging coatings businesses, the specialty coatings and materials business, the fiber glass business and the Asia Pacific region. In addition, for the period January through September, Mr. Sekmakas' business performance component was a composite of the results of the flat glass business. The composite performance of these businesses met performance objectives for pre-tax, pre-interest earnings, working capital reductions and sales volume/mix growth and resulted in a payout of 130%.

Mr. Knavish's business performance component, for the period January through February, was a composite of the results of the protective and marine coatings business and the Latin America region. In addition, for the period March through December, Mr. Knavish's business performance component was a composite of the results of the automotive original equipment manufacturer business and the Latin America region. The composite performance of these businesses met performance objectives for pre-tax, pre-interest earnings, working capital reductions and sales volume/mix growth and resulted in a payout of 160%.

The level of achievement of corporate and personal performance objectives for 2016 for Messrs. McGarry, Bunch, Sklarsky and Bost corresponded to payouts of 134%, 126%, 127% and 128% of target, respectively. The level of achievement of business, corporate and personal performance objectives for 2016 for Messrs. Sekmakas and Knavish corresponded to payouts of 132% and 159% of target, respectively. The annual incentive awards actually paid to each of these executives for 2016 are shown in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table on page 40. While serving as executive officers over the past three years, the annual incentive awards for these executive officers have ranged from 122% to 191% of target.

Annual incentive awards are payable in cash, except that any executive who does not meet the stock ownership requirements described under "PPG Stock Ownership Requirements" on page 39 receives 20% of his or her annual incentive award in the form of PPG common stock. Such stock is restricted from sale by such executive for a period of between two and five years, depending upon the level of stock ownership of the executive. In addition, for officers who have been subject to the policy for more than five years at their current requirement level and have not met the ownership requirement, 100% of the vested shares delivered from the PBRSU award and TSR share award must be held by the officer for a minimum of one year and until the requirement is met. U.S.-based participants are entitled to defer part or all of an annual incentive award under our deferred compensation plan. All of the executive officers named in the Summary Compensation Table have met their stock ownership requirement, except for Mr. Sklarsky, who joined the Company in April 2013 and was within his five-year compliance period at the time of his retirement. For additional information concerning our deferred compensation plan, see "Deferred Compensation Opportunities" on page 37.

Long-Term Incentive Compensation

Our compensation committee believes that long-term incentive compensation is an important component of our program because it has the effect of retaining executives, aligning executives' financial interests with the interests of shareholders and incentivizing achievement of PPG's long-term strategic goals. Payment of long-term incentive awards is based solely on Company performance. Grants are targeted at levels that approximate market value for comparable positions, utilizing the same compensation data used for setting total annual compensation. Each February, the committee reviews and approves equity-based compensation for that year to be granted to executive officers. Three types of long-term incentive awards are granted annually to executive officers:

•

Stock options;

•

Total Shareholder Return contingent shares, or TSR shares; and

•

Performance-based Restricted Stock Units, or PBRSUs.

The number of stock options, TSR shares and PBRSUs granted to executive officers is intended to represent an estimated potential value that, when combined with total annual compensation, as discussed above, will approximate the market value of total annual and long-term compensation paid to executives in our comparator group and in a cross-section of general industrial companies represented in nationally-recognized executive compensation surveys.

These types of long-term incentive awards were selected to provide a program that focuses on different aspects of long-term performance: stock price appreciation, total return to shareholders and earnings-per-share growth and cash flow return on capital. The estimated potential value of the awards granted to each executive officer is delivered equally through each instrument, so that approximately one-third of the value of the total award is in stock options, one-third is in performance-based RSUs, and one-third is in TSR shares. The compensation committee selected

equal distribution to emphasize its view that each of the three equity-based vehicles serves a particular purpose and is equally important in supporting our long-term compensation strategy.

Stock Options.    Stock options provide our executive officers with the opportunity to purchase and maintain an equity interest in PPG and to share in the appreciation of the value of our stock. All stock options granted to executive officers in 2016 were granted from our shareholder-approved Omnibus Incentive Plan. Some features of our stock option program include:

•

Options become exercisable on the third anniversary of the date of grant;

•

The term of each grant does not exceed ten years;

•

The exercise price is equal to the closing market price on the date of grant (we do not backdate or grant discounted stock options);

•

We do not grant options with "reload" or "restored" provisions; and

•

Repricing of stock options is prohibited.

We continue to use stock options as a long-term incentive because stock options focus the management team on delivering levels of company financial performance over a longer term that contribute to shareholder value. For additional information concerning the timing of grants of stock options, see "Our Policies with Respect to the Granting of Equity Awards" on pages 38 through 39. In February 2016, the following stock options were awarded to each of the executive officers named in the Summary Compensation Table: Mr. McGarry, 111,867; Mr. Sklarsky, 35,425; Mr. Sekmakas, 29,831; Mr. Bost, 23,306; and Mr. Knavish, 9,300. Mr. McGarry was awarded a one-time grant of 16,760 stock options in September 2016 in conjunction with his promotion to Chairman and Chief Executive Officer. Such awards are consistent with our program to distribute long-term incentive awards equally among three different equity-based vehicles, as discussed above.

TSR Shares.    TSR shares represent a contingent share grant that is made at the beginning of a three-calendar-year performance period and vests on the last day of the performance period. The grant is settled in a combination of cash and shares of PPG common stock at the end of the performance period. The award amount generated by the grant is based on PPG's total shareholder return relative to the S&P 500 comparison group. This comparison group represents the entire S&P 500 Index as it existed at the beginning of the performance period, excluding any companies that have been removed from the Index because they ceased to be publicly traded during the performance period. The calculation of total shareholder return assumes that all dividends were reinvested. Summarized below are the material provisions of the TSR share program:

 

​ ​

Table of Contents

If minimum performance is not achieved, no payment is made with respect to the TSR share grant. If performance is above target, payment may exceed the original number of contingent TSR shares awarded. Target performance is set at the 60th percentile rank, which allows for a 100% payout only if our performance is greater than the median performance for the comparison set of companies. The minimum and maximum number of shares that may be issued upon settlement of a TSR share grant ranges from 0% to 220% of the original number of contingent TSR shares awarded. Dividend equivalents are awarded at the end of the performance period, based on the actual number of shares earned and paid to an executive. TSR shares are intended to reward executives only when we provide a greater long-term return to shareholders relative to a percentage of the comparison set of companies, which is consistent with our pay-for-performance compensation philosophy.

In February 2016, the following TSR shares were awarded to each of the executive officers named in the Summary Compensation Table: Mr. McGarry, 21,053; Mr. Sklarsky, 6,667; Mr. Sekmakas, 5,614; Mr. Bost, 4,386; and Mr. Knavish, 1,755. Mr. McGarry was awarded a one-time grant of 3,145 TSR shares in September 2016 in conjunction with his promotion to Chairman and Chief Executive Officer. Such awards are consistent with our program to distribute long-term incentive awards equally among three different equity-based vehicles, as discussed above under "Long-Term Incentive Compensation."

The performance period for the TSR shares granted in 2014 ended on December 31, 2016. PPG's total shareholder return was measured against that of the S&P 500 (as described above) over the three-year period ending December 31, 2016. PPG's ranking on this performance measure was at the 36th percentile, resulting in payouts at 42.9% of target. The payouts were distributed 50% in shares of PPG common stock and 50% in cash. The cash payment was calculated based on the average PPG stock closing price during the month of December 2016. Payouts to the executive officers named in the Summary Compensation Table for the 2014 TSR grants were: Mr. McGarry, 1,539 shares (aggregate of two grants in 2014) and $148,002; Mr. Bunch, 5,437 shares and $523,203; Mr. Sklarsky, 1,224 shares and $117,689; Mr. Sekmakas, 1,071 shares and $102,966; Mr. Bost, 765 shares and $73,616; and Mr. Knavish, 299 shares and $28,677. Such share payouts, which vested in December 2016, are reflected in the Option Exercises and Stock Vested table on page 44.

Performance-based RSUs.    Performance-based RSUs represent a contingent share grant that is made at the beginning of a three-calendar-year performance period and vests on the last day of the performance period. If we achieve certain pre-determined performance thresholds, payment is settled in shares of PPG common stock in the February immediately after the end of the three-year performance period. The performance criteria for each year in the three-year performance period are 10% growth in adjusted earnings-per-diluted share and 12% cash flow return on capital, taking into account the same adjustment categories utilized by the compensation committee in determining adjusted earnings-per-diluted share for purposes of annual incentive awards (see "Annual Incentive Awards" above). If minimum performance is not achieved, no shares are issued with respect to the grant. If performance is above target, the number of shares issued may exceed the original number of contingent shares awarded. The minimum and maximum number of shares that may be issued upon settlement of an PBRSU ranges from 0% to 180% of the original number of contingent shares awarded, depending on the number of goals attained during the three-year period (see the table below for a breakdown of the payout percentages). No dividend equivalents are awarded on performance-based RSUs. By including performance-based RSUs in the long-term incentive mix, executives are rewarded when financial performance objectives are achieved over an extended period of time. Summarized below are the material provisions of the performance-based RSUs:

​ ​

Table of Contents

In February 2016, the following PBRSUs were awarded to each of the executive officers named in the Summary Compensation Table: Mr. McGarry, 22,058; Mr. Sklarsky, 6,985; Mr. Sekmakas, 5,882; Mr. Bost, 4,595; and Mr. Knavish, 1,755. Mr. McGarry was awarded a one-time grant of 3,280 PBRSUs in September 2016 in conjunction with his promotion to Chairman and Chief Executive Officer. Such awards are consistent with our program to distribute long-term incentive awards equally among three different equity-based vehicles, as discussed above under "Long-Term Incentive Compensation."

The performance period for the PBRSUs granted in 2014 ended on December 31, 2016. For such 2014 grants, five of the annual goals were achieved in three years, yielding payouts at 150% of target. Specifically, the results were as follows:

PBRSU Performance Measures for 2014-2016 Performance Period

The Company made share payouts to the executive officers named in the Summary Compensation Table for the 2014 PBRSU grants as follows: Mr. McGarry, 11,211 (aggregate of two grants in 2014); Mr. Bunch, 44,529; Mr. Sklarsky, 8,907; Mr. Sekmakas, 7,791; Mr. Bost, 5,565; and Mr. Knavish, 2,085. Such payouts, which vested in December 2016, are reflected in the Option Exercises and Stock Vested table on page 44.

Mr. Bunch was awarded a one-time grant of 37,053 time-based RSUs in February 2016. These time-based RSUs vested on February 17, 2017.

Perquisites and Other Benefits

In addition to the annual and long-term compensation described above, executive officers named in the Summary Compensation Table receive certain perquisites and other benefits. Such perquisites include financial counseling services and limited personal use of PPG's corporate aircraft. At the direction of the compensation committee, in 2011, executive officer perquisites were reviewed and reduced. Effective January 1, 2012, personal club memberships were discontinued and financial counseling benefits were limited to current participants only. Other benefits for our executive officers may include executive life insurance and Company matching contributions under our Deferred Compensation Plan. These perquisites and other benefits are provided to increase the availability of the executives to focus on the business of the enterprise or because we believe they are important to our ability to attract and retain top-quality executive talent. The costs to PPG associated with providing these benefits for executive officers named in the Summary Compensation Table are reflected in the "All Other Compensation" column of the Summary Compensation Table on page 40 and in the All Other Compensation Table on page 41.

We also provide other benefits, such as medical, dental and life insurance and disability coverage, to each executive named in the Summary Compensation Table under our benefit plans, which are also provided to most eligible U.S.-based salaried employees. In addition, all of our U.S.-based executive officers are eligible to participate in the PPG Industries Foundation Matching Gift Program, which encourages charitable donations by all of our U.S. employees by matching his or her contributions to eligible institutions. Contributions of up to a total of $10,000 per year may be matched under the program. Most charitable organizations are eligible for the Matching Gifts Program, with a few exceptions. The value of these benefits is not included in the Summary Compensation Table because such benefits are made available on a Company-wide basis to most U.S. salaried employees. We also provide vacation and other paid holidays to all employees, including the executive officers named in the Summary Compensation Table, which are comparable to those provided at other large companies.

Deferred Compensation Opportunities

Another aspect of our executive compensation program is our Deferred Compensation Plan. The plan is a voluntary, non-tax qualified, unfunded, deferred compensation plan available to all U.S.-based executive officers and other participants in our management incentive plans to enable them to save for retirement by deferring a portion of their current compensation. The plan also provides eligible employees with supplemental contributions equal to the contributions they would have received under our Employee Savings Plan, but for certain limitations under the Internal Revenue Code. Under the plan, compensation may be deferred until death, disability, retirement or termination or, in the case of the cash portion of certain incentive awards, other earlier specified dates the participants may select. Deferred amounts (other than the PPG common stock portion of deferred incentive awards, which must be invested in PPG stock) are credited to an investment account that earns a return based on the investment options chosen by the participant. The value of a participant's investment account is based on the value of the investments selected. Benefits are paid out of our general assets. For additional information concerning our Deferred Compensation Plan, see "Defined Contribution Retirement Plans and Deferred Compensation Plan" and the accompanying Non-Qualified Deferred Compensation Table on pages 46 through 47.

Retirement Plans

For certain longer-serving, U.S.-based, salaried employees, we maintain both a tax-qualified defined benefit pension plan, called Retirement Plan C, and a non-qualified defined benefit pension plan, called the Non-Qualified Retirement Plan. U.S.-based salaried employees hired on or after January 1, 2006 are not eligible to participate in these plans. Each of the U.S.-based executive officers named in the Summary Compensation Table participate in these plans, with the exception of Mr. Sklarsky. In 2013, the Company reorganized its two U.S. tax-qualified defined benefit pension plans into six plans. The named executive officers who formerly participated in the Retirement Income Plan now participate in Retirement Plan C. The compensation covered by Retirement Plan C, which is compulsory and noncontributory, is the base salary of a participant as limited by applicable Internal Revenue Service regulations. Our Non-Qualified Retirement Plan is an unfunded supplemental plan that provides benefits paid out of our general assets in an amount substantially equal to the difference between the amount that would have been payable under Retirement Plan C, in the absence of legislation limiting pension benefits and earnings that may be considered in calculating pension benefits, and the amount actually payable under Retirement Plan C. The Non-Qualified Retirement Plan also includes a benefit based on bonus awards for certain U.S. management bonus program participants. We believe this supplemental retirement benefit is competitive with that provided by other companies with which we compete for executive talent. For additional information concerning our retirement plans, see "Pension Benefits" and "Defined Contribution Retirement Plans and Deferred Compensation Plan" on pages 44 through 47.

Through December 31, 2015, we maintained a tax-qualified defined contribution retirement plan, called the Defined Contribution Retirement Plan, which was established by PPG for certain employees hired on or after January 1, 2006. Mr. Sklarsky participated in the Defined Contribution Retirement Plan. The plan was funded by contributions made by the Company. Contributions were between 2% and 5% of a participant's eligible plan compensation, based on age and years of service. If contributions made for the benefit of an executive were limited due to requirements of the Internal Revenue Code, we credited such excess contributions to the executive officer's account in the Deferred Compensation Plan. An executive had a fully vested benefit under the plan upon completing three years of service with the Company, and when the employee was within ten years of his or her Social Security normal retirement age or upon termination of employment after reaching early retirement age. On January 1, 2016, the Defined Contribution Retirement Plan was terminated and all balances were transferred to the PPG Industries Employee Savings Plan. Former participants in the Defined Contribution Retirement Plan now receive the same contributions they would have received under the Defined Contribution Retirement Plan as additional Company contributions to the Employee Savings Plan.

The PPG Industries Employee Savings Plan covers substantially all employees in the U.S. The Company makes matching contributions to the Savings Plan, at management's discretion, based upon participants' savings, subject to certain limitations. For most participants not covered by a collective bargaining agreement, Company-matching contributions are established each year at the discretion of the Company and are applied to participant savings up to a maximum of 6% of eligible participant compensation. Employees can contribute from 1% to 50% of eligible plan compensation to the Savings Plan, subject to certain Plan or legal limits that may apply. Employees are always 100% vested in any money employees contribute or the Company contributes to the Savings Plan as a matching contribution. All of our executive officers participate in the Savings Plan. Executive officers and other employees who were participants in the former Defined Contribution Retirement Plan now receive the same contributions they would

​ ​

have received under the Defined Contribution Retirement Plan as an additional Company contribution to the Employee Savings Plan. These contributions vest upon completion of three years of service with the Company.

Change In Control Agreements

We have agreements in place with each of the executive officers named in the Summary Compensation Table providing for their continued employment for a period of up to three years in the event of an actual or threatened change in control of PPG (as "change in control" is defined in the agreements). We believe that these agreements serve to maintain the focus of our senior executives and ensure that their attention, efforts and commitment are aligned with maximizing the success of PPG and shareholder value. These agreements avoid distractions involving executive management that arise when the Board is considering possible strategic transactions involving a change in control and assure continuity of executive management and objective input to the Board when it is considering any strategic transaction. For additional information concerning our change in control agreements, see "Potential Payments Upon Termination or Change in Control" on pages 48 through 53.

Regulatory Considerations

The tax and accounting consequences of utilizing various forms of compensation are considered when adopting new or modifying existing compensation programs. For example, we considered limitations on the deductibility of personal use of corporate aircraft under the American Jobs Creation Act when adopting our policies regarding use of our aircraft by executive officers. In addition, we have administered our incentive and equity compensation programs, severance plans and change in control agreements in compliance with federal tax rules affecting non-qualified deferred compensation.

Under Section 162(m) of the Internal Revenue Code, as amended, publicly-held corporations may not take a tax deduction for compensation in excess of $1 million paid to any of the U.S.-based executive officers named in the Summary Compensation Table (except the chief financial officer) during any fiscal year. There is an exception to the $1 million limitation for performance-based compensation meeting certain requirements. To maintain flexibility in compensating executives in a manner designed to promote varying corporate goals, the compensation committee has not adopted a policy requiring all compensation to be deductible under Section 162(m) and reserves the right to structure compensation arrangements and issue awards that may not be deductible under Section 162(m). However, the committee considers, among other factors, deductibility under Section 162(m) with respect to compensation arrangements for executives. We have designed our annual and long-term incentive compensation programs for executives in a manner that is intended to qualify as performance-based compensation under Section 162(m); however, these programs may not qualify from time to time.

Financial Restatement

It is our policy that we will, to the extent permitted by governing law, seek recoupment of incentive compensation paid to any executive officer where:

•

the payment was predicated upon the achievement of certain financial results that were subsequently the subject of a restatement;

•

the executive officer is found to have engaged in fraud or misconduct that caused or partially caused the need for the restatement; and

•

a lower payment would have been made to the executive officer based upon the restated financial results.

In each such instance, we will, to the extent practicable, seek to recover the amount by which the individual executive officer's incentive compensation for the relevant period exceeded the payment that would have been made based on the restated financial results, plus a reasonable rate of interest.

Our Policies with Respect to the Granting of Equity Awards

Equity awards may be granted by either the compensation committee or its delegate. The committee only delegates authority to grant equity awards to employees who are not executive officers, and only in aggregate amounts not exceeding amounts approved by the committee. The Board generally does not grant equity awards, although the committee regularly reports its activity, including approval of grants, to the Board.

​ ​

---

Table of Contents

Timing of Grants.    Equity awards are granted in February at a regularly scheduled meeting of the compensation committee, and generally further grants are not made for the remainder of the year. These meetings occur approximately one month after the release of our earnings for the immediately preceding year. On limited occasions, grants may occur on an interim basis, primarily for the purpose of approving a compensation package for a newly hired or promoted executive officer. The timing of these grants is driven solely by the activity related to the need for the hiring or promotion, not our stock price or the timing of any release of Company information.

Option Exercise Price.    The exercise price of a newly granted stock option is the closing price on the New York Stock Exchange on the date of grant. With respect to the occasional interim grants to a newly hired or promoted executive, the exercise price is the closing price on the New York Stock Exchange on the date of grant, which is the later of the approval date or the hire or promotion date; provided, however, that if the date of hire or promotion would fall within a Company imposed blackout period, the grant date will be the first business day following such blackout period.

PPG Stock Ownership Requirements

The compensation committee also believes that it is in the best interests of shareholders for our officers to own a significant amount of PPG common stock, thereby aligning their interests with the interests of shareholders. Accordingly, in 2003, the compensation committee implemented stock ownership requirements applicable to all of our officers, based on a multiple of base salary. The current stock ownership requirements are:

Ownership for purposes of these requirements includes shares of PPG common stock personally owned, as well as all stock holdings in PPG's savings plan and deferred compensation accounts. Unexercised options and unvested shares awarded under our long-term incentive plans are not counted for these purposes. Officers are expected to meet these ownership requirements within five years of election, appointment or promotion. All executive officers named in the Summary Compensation Table have met their ownership requirement, except for Mr. Sklarsky who was within his five-year compliance period at the time of his retirement.

Securities Trading Policy

PPG officers and directors may not engage in any transaction in which they may profit from short-term speculative swings in the value of PPG's securities. This prohibition includes "short sales" (selling borrowed securities that the seller hopes can be purchased at a lower price in the future) or "short sales against the box" (selling owned, but not delivered securities), "put" and "call" options (publicly available rights to sell or buy securities within a certain period of time at a specified price) and other hedging transactions designed to minimize an executive's risk inherent in owning PPG stock, such as zero-cost collars and forward sale contracts. In addition, officers may not hold PPG stock in a margin account and may not pledge PPG stock as collateral for a loan. This policy is designed to ensure compliance with all insider trading rules.

Pension Benefits

For certain longer-serving, U.S.-based, salaried employees we maintain both a tax-qualified defined benefit pension plan, called Retirement Plan C, and a non-qualified defined benefit pension plan, called the Non-Qualified Retirement Plan. Employees hired on or after January 1, 2006 are not eligible to participate in these plans. Each of the executive officers named in the Summary Compensation Table participates in these plans, with the exception of Mr. Sklarsky. The table below shows the present value of accumulated benefits payable to each such named executive officer as of December 31, 2016, including the number of years of service credited to each such named executive officer, under each of Retirement Plan C and the Non-Qualified Retirement Plan, determined using interest rate and mortality rate assumptions consistent with those used in our financial statements. The material terms of Retirement Plan C and the Non-Qualified Retirement Plan are described below.

Pension Benefits Table (2016)

The values reflected in the "Present Value of Accumulated Benefit" column of the Pension Benefits Table are equal to the actuarial present value of each officer's accrued benefit under the applicable plan as of December 31, 2016,

using the same actuarial factors and assumptions used for financial statement reporting purposes, except that retirement age is assumed to be normal retirement age as defined in the applicable plan. These assumptions are described under Note 12 to our Financial Statements for the year ended December 31, 2016, which is located on pages 57 through 63 of our Annual Report on Form 10-K. In accordance with Item 402(h) of Regulation S-K, the present value amounts are calculated using a 4.39% discount rate for Retirement Plan C and 4.24% discount rate for the Non-Qualified Retirement Plan. The lump-sum payment amounts for the Non-Qualified Pension Plan are calculated in accordance with the relevant provisions of the Non-Qualified Pension Plan using the Pension Benefit Guaranty Corporation discount rate of 1.25% as in effect on December 31, 2016, rather than the 4.24% discount rate used for financial statement reporting purposes. In connection with his transition to Executive Chairman, Mr. Bunch's benefit under the Non-Qualified Pension Plan was frozen effective September 1, 2015. Subsequent to September 1, 2015, Mr. Bunch did not accrue any benefits under the Non-Qualified Pension Plan due to service or pay. From September 1, 2015 through Mr. Bunch's retirement, his frozen benefit earned interest at 120% of the September 2015 long-term Applicable Federal Rate, as determined by the Internal Revenue Service.

The benefit payable under Retirement Plan C is a function of the participant's five-year average annual covered base compensation for the highest five consecutive years out of the final ten years immediately prior to retirement and credited years of service. In January 2011, Retirement Plan C was amended such that eligible employees with combined age and service points fewer than 60 and actively employed by the Company as of December 31, 2011 ceased to accrue benefits under Retirement Plan C as of December 31, 2011. Eligible employees with combined age and service points of 60 or more and actively employed by the Company at December 31, 2011 will continue to accrue benefits under Retirement Plan C until the earlier of their retirement date or December 31, 2020. When benefits cease to accrue under Retirement Plan C, eligible employees will earn future retirement benefits through the PPG Industries Employee Savings Plan. The Non-Qualified Retirement Plan's benefit is supplemental to the qualified plan's benefit in that the Non-Qualified Retirement Plan provides a benefit that is substantially equal to the difference between the amount that would have been payable under the qualified Retirement Plan C, in the absence of legislation limiting the compensation covered by the plan, and the amount actually payable under Retirement Plan C. The Non-Qualified Retirement Plan also includes a benefit based on bonus awards for certain U.S. management bonus program participants. The benefit payable under the Non-Qualified Plan is determined in the same manner as for Retirement Plan C with regard to credited service and base salary above legislative limits; incentive payments are factored in by using the average of the highest five payments during the last ten years prior to retirement.

Retirement Plan C contains the following material terms:

•

The normal form of benefit is a life annuity for unmarried participants and a joint and 50% survivor annuity for married participants;

•

A participant may elect out of the normal form of benefit and receive an actuarially-equivalent alternative form of benefit, including a single life annuity (for a married participant) or a joint and survivor annuity with a survivor benefit ranging from 1%-100%, as selected by the participant;

•

There is no lump-sum benefit option;

•

A participant may elect early retirement up to ten years prior to the participant's normal retirement age, subject to reduction of the retirement benefit to reflect the early commencement of the benefit; and

•

A participant has a fully vested benefit under the plan upon completing five years of service or reaching early retirement age.

The Non-Qualified Plan contains the following material terms:

•

A participant is entitled to a distribution upon reaching the later of his or her early retirement date (as defined in the qualified plan) or the participant's termination of employment;

•

The normal form of payment for benefits at retirement for the group of participants that includes each of the executive officers named in the Summary Compensation Table who participates in the plan is a lump-sum payment; and

•

A participant has a fully vested benefit under the plan upon completing five years of service or reaching early retirement age, but his or her accrued benefit is subject to forfeiture if the participant engages in any competitive activity, or other activity that is deemed contrary or harmful to the interests of PPG.

Defined Contribution Retirement Plans and Deferred Compensation Plan

Through December 31, 2015, we maintained a tax-qualified defined contribution retirement plan, called the Defined Contribution Retirement Plan, which was established by PPG for certain employees hired on or after January 1, 2006. Mr. Sklarsky participated in the Defined Contribution Retirement Plan. The plan was funded by contributions made by the Company. Contributions were between 2% and 5% of a participant's eligible plan compensation, based on age and years of service. If contributions made for the benefit of an executive were limited due to requirements of the Internal Revenue Code, we credited such excess contributions to the executive officer's account in the Deferred Compensation Plan. An executive had a fully vested benefit under the plan upon completing three years of service with the Company, and when the employee was within ten years of his or her Social Security normal retirement age or upon termination of employment after reaching early retirement age. On January 1, 2016, the Defined Contribution Retirement Plan was terminated and all balances were transferred to the PPG Industries Employee Savings Plan. Former participants in the Defined Contribution Retirement Plan now receive the same contributions they would have received under the Defined Contribution Retirement Plan as additional Company contributions to the Employee Savings Plan.

The PPG Industries Employee Savings Plan covers substantially all employees in the U.S. The Company makes matching contributions to the Savings Plan, at management's discretion, based upon participants' savings, subject to certain limitations. For most participants not covered by a collective bargaining agreement, Company-matching contributions are established each year at the discretion of the Company and are applied to participant savings up to a maximum of 6% of eligible participant compensation. Employees can contribute from 1% to 50% of eligible plan compensation to the Savings Plan, subject to certain Plan or legal limits that may apply. Employees are always 100% vested in any money employees contribute or the Company contributes to the Savings Plan as a matching contribution. All of our executive officers participate in the Savings Plan. Executive officers and other employees who were participants in the former Defined Contribution Retirement Plan now receive the same contributions they would have received under the Defined Contribution Retirement Plan as an additional Company contribution to the Employee Savings Plan. These contributions vest upon completion of three years of service with the Company.

In the U.S., we maintain the Deferred Compensation Plan to allow participants, including each of the U.S.-based executive officers named in the Summary Compensation Table, to defer a portion of their compensation in a phantom PPG stock account or other phantom investment accounts. The amount deferred earns a return based on the investment options selected by the executive officer. Executive officers may elect to defer up to 50% of their base salary, and up to 100% of any incentive award, TSR share award and restricted stock unit award that the executive officer may be entitled to receive. All dividend equivalents earned on TSR share award grants are deferred into the Deferred Compensation Plan. We also may make certain additional contributions to the executive officer's account. For example, if the executive officer's contributions under the Employee Savings Plan are limited due to requirements of the Internal Revenue Code, we will credit such excess contributions to the executive officer's account under the Deferred Compensation Plan. The executive officer is always fully vested in compensation that he or she elects to have deferred into the plan and any contributions made on behalf of the executive officer related to the Employee Savings Plan. Company contributions are invested proportionally into the investment options chosen by the employee.

The table below shows the Deferred Compensation Plan's current investment options and their respective annual rate of return for the year ended December 31, 2016, as reported by the administrator of the plan.

The amount owed to executive officers under the Deferred Compensation Plan is an unfunded and unsecured general obligation of PPG. An executive officer receives a distribution of the balance in his or her plan account upon retirement, death, disability, termination of employment, a scheduled payment date, financial hardship (for amounts deferred prior to January 1, 2005) or unforeseeable emergency (for amounts deferred after December 31, 2004). Distributions can be in the form of a lump sum or installments. Payment can commence at the time of separation or, in certain situations, can be deferred until a later point in time. Compensation deferred prior to January 1, 2005 and related earnings are distributed according to the executive officer's election. Compensation deferred after

​

Table of Contents

December 31, 2004 and related earnings are distributed according to the executive officer's election only in the case of retirement (no earlier than six months following retirement). In the case of disability or termination, the distribution is made in a lump sum on the date that is the later of (i) the first day of the first quarter of a plan year that is six months and ten days following the separation or (ii) January 1 of the year following the separation. In the case of death, a distribution is made to the executive officer's beneficiary as soon as administratively possible. Distributions from the PPG stock account are in the form of PPG common stock and distributions from all other investment options are in cash.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The tables below reflect the amount of compensation to each of the executive officers named in the Summary Compensation Table in the event of termination of such executive's employment under certain circumstances. The amounts shown assume that such termination was effective as of December 31, 2016, and thus includes amounts earned through such time and are estimates of the amounts that would be paid out to the executives upon their termination. The actual amounts to be paid out can only be determined at the time of such executive's separation from PPG.

For purposes of calculating the estimated potential payments to our officers under the Non-Qualified Pension Plan, as reflected in the tables below, we have used the same actuarial factors and assumptions used for financial statement reporting purposes and set forth under Note 12 to our Financial Statements for the year ended December 31, 2016, which is located on pages 57 through 63 of our Annual Report on Form 10-K. However, the amounts reflected in the tables below for the Non-Qualified Pension Plan are calculated in accordance with the relevant provisions of the Non-Qualified Pension Plan using the 4.24% discount rate for our U.S. non-qualified defined benefit pension plan that is used for financial statement reporting purposes.

Potential Payments and Benefits Upon Termination

The first column of each table below sets forth the payments to which the officer would be entitled, other than accrued but unpaid base salary and any benefits payable or provided under broad-based employee benefit plans and programs, in the event of a termination of the officer's employment for any reason by PPG or the officer, and assuming such termination occurred prior to, or did not otherwise arise in connection with, a change in control of PPG. The second column of each table reflects payments that would be due in the event of the officer's termination of employment due to death prior to a change in control of PPG. In any of these events, we are not obligated to provide other health or welfare benefits or any special severance payments, accelerated vesting of equity compensation or tax gross-ups to the officers.

Potential Payments and Benefits Upon Termination Following, or in Connection with, a Change in Control of PPG

We have entered into change in control agreements with our executive officers named in the Summary Compensation Table and with certain other officers. The change in control agreements have three-year terms, which terms are automatically extended for one year upon each anniversary unless a notice not to extend is given by PPG. If a "change in control" occurs during the term of an agreement, then the agreement becomes operative for a fixed three-year period. The agreements provide generally that the officer's terms and conditions of employment (including position, location, compensation and benefits) will not be adversely changed during the three-year period after a change in control of PPG. The change in control agreements also contain confidentiality provisions prohibiting the officer from divulging or communicating, without our prior consent or except as required by law, any confidential information, knowledge or data relating to PPG or its business during the officer's employment and at all times thereafter. In 2007, 2010, 2012 and 2013, the Officers—Directors Compensation Committee approved certain changes to our change in control agreements, which are described under "Changes to Form of Change in Control Agreement" on page 51.

Termination For Cause or Other Than For Good Reason.    Under the change in control agreements, in the event of an officer's termination of employment by PPG for cause or by the officer other than for good reason during the three-year period following a change in control, the officer will receive payment only of his or her accrued but unpaid base salary and any benefits payable or provided under broad-based employee benefit plans and programs.

Termination Without Cause or For Good Reason.    If PPG terminates the officer's employment (other than for cause, death or disability) or the officer terminates his or her employment for good reason during the three-year period following a change in control, and upon certain terminations prior to a change in control or in connection with or in anticipation of a change in control, the officer is generally entitled to receive the following payments and benefits:

•

a pro-rata bonus for the year of the date of termination based on the officer's highest annual bonus during the three years prior to the change in control or the annual bonus for the most recent fiscal year after the change in control, whichever is higher (such higher amount referred to herein as the "highest annual bonus");

•

three times the officer's annual base salary;

•

three times the officer's highest annual bonus;

•

a lump-sum payment having an actuarial present value equal to the additional pension benefits the officer would have received if he or she had continued to be employed by PPG for an additional three years for purposes of both age and service credit, assuming the officer's compensation for each such additional year is equal to his or her annual base salary prior to the change in control (or any higher salary thereafter) and his or her annual bonus

​

​

---

Table of Contents

is at least equal to the officer's highest annual bonus during the three years prior to the change in control (the "Pension Differential");

•

a lump-sum payment equal to the present value of any employer contributions the executive would have received or accrued under PPG's defined contribution retirement plans and arrangements (whether qualified or non-qualified) in which the executive participates if the executive's employment continued for an additional three years in respect of retirement benefits provided in the form of a defined contribution retirement plan, program or arrangement, but excluding any salary or pay deferral contributions to such plans or arrangements that are deemed to be employer contributions under applicable law;

•

continued medical, dental and life insurance benefits for three years and continued age and service credit for purposes of determining the officer's eligibility for retiree medical benefits;

•

continued payment of financial counseling expenses for the officer for three years; and

•

a payment in an amount sufficient to make the officer whole for any excise tax on excess parachute payments imposed under Section 4999 of the Internal Revenue Code.

The table below sets forth the amounts each executive officer named in the Summary Compensation Table would be entitled to receive, other than accrued but unpaid base salary and any benefits payable or provided under broad-based employee benefit plans and programs, in the event of a termination of the executive officer's employment by PPG without cause or by the executive officer for good reason following or in connection with a change in control of PPG.

For purposes of calculating the estimated potential payment to such executive officers with respect to the Pension Differential under the change in control agreements, as reflected in the table below, we have used the same actuarial factors and assumptions used for financial statement reporting purposes and set forth under Note 12 to our Financial Statements for the year ended December 31, 2016, which is located on pages 57 through 63 of our Annual Report on Form 10-K, including a discount rate of 4.39% for Retirement Plan C and 4.24% for our U.S. non-qualified defined benefit pension plan and assuming a lump-sum payment of the Pension Differential.

Termination During the 30-Day Window Period.    Under certain of our change in control agreements, if an officer terminates his or her employment for any reason during a 30-day window period following the first anniversary of the change in control, the officer will be entitled to the payments and benefits described above, except that the multiplier of three referenced above would be two for purposes of all payments and benefits for which the multiplier is relevant.

Definitions.    For purposes of the agreements, the terms set forth below generally have the meanings described below.

"Change in Control" generally includes the occurrence of any of the following events or circumstances:

(i)

the acquisition of 20% or more of the outstanding shares of PPG or the voting power of the outstanding voting securities of PPG, other than any acquisition from or by PPG or any PPG-sponsored employee benefit plan;

(ii)

a change in our Board's composition such that a majority of the Board's members does not include those who were members at the date of the agreement or members whose election or nomination was approved by a majority of directors who were on the Board at the date of the agreement;

(iii)

shareholder approval of a reorganization, merger or consolidation or sale of substantially all of the assets of PPG, unless following such transaction PPG's historic shareholders retain at least 60% ownership of the surviving entity, no shareholder acquires a 20% or more ownership interest in the surviving entity and a majority of the surviving entity's board of directors were members of our Board at the time such transaction was approved;

(iv)

shareholder approval of a dissolution or liquidation of PPG; or

(v)

a determination by a majority of our Board that a change in control has occurred.

"Cause" generally means (i) the willful and continued failure of the officer to perform his or her duties; or (ii) the willful engaging by the officer in illegal conduct or gross misconduct that is materially and demonstrably injurious to PPG.

"Good reason" generally means (i) the assignment of duties inconsistent with the officer's position, authority, duties or responsibilities in effect at the time of the change in control, or any other action resulting in a diminution in such position, authority, duties or responsibilities, other than isolated and inadvertent action not taken in bad faith that is

remedied promptly; (ii) failure to provide the employment compensation and benefits required under the change in control agreement, other than an isolated and inadvertent failure not occurring in bad faith that is remedied promptly; or (iii) a relocation or substantial change in the officer's workplace or the company's requiring the officer to travel on company business to a substantially greater extent than required immediately prior to the change in control.

Changes to Form of Change in Control Agreement.    The Officers—Directors Compensation Committee has made modifications to the form of change in control agreement for officers in response to current trends in executive compensation and to a shareholder proposal that was supported by shareholders at the 2007 annual meeting of shareholders. PPG began entering into the revised agreements in 2008 with certain newly hired or promoted officers.

Key revisions to the change in control agreement in 2007 included:

•

Modification of the definition of "change in control" to require "consummation" of a reorganization, merger or consolidation or sale of substantially all of the assets of PPG.

•

Modification of the definition of "compensation" to include "target" bonus instead of the "highest" bonus over the last three years. This change affects the cash payment and the Pension Differential calculation.

•

Modification of certain termination provisions, including elimination of the window period termination.

•

Modification of the excise tax and gross-up provision to replace the full gross up with a "conditional" gross up, which provides for a reduction in change in control payments if such payments trigger an excise tax by a limited amount.

•

Elimination of the provisions providing for the payment of financial counseling and legal expenses.

In 2010, 2012 and 2013, the Officers—Directors Compensation Committee made additional modifications to the form of change in control agreement for officers in response to current trends in executive compensation. The key revisions to the change in control agreement for 2010 were to eliminate the excise tax gross-up entirely and include a "conditional" payment limitation, which provides for a reduction in change of control payments if such payments would trigger an excise tax, unless a larger amount would be received on an after-tax basis without a payment reduction. The key revisions made in 2012 were to change the definition of Retirement and the associated benefits related to retirement to ensure that all applicable provisions are applied properly for executives who only participated in the former PPG Defined Contribution Retirement Plan and non-U.S. executives who do not participate in either Retirement Plan C or the former Defined Contribution Retirement Plan. The key revision made in 2013 was to eliminate potential double payments under other PPG severance provisions or statutory requirements and the change in control agreement.

Equity Acceleration

In the event of a change in control of PPG, the Company stock plans and award agreements entered into prior to 2009 provide that the participant will be entitled to full vesting acceleration of his or her unvested stock options, TSR awards and restricted stock units. For award agreements entered into in 2009 and thereafter, in the event of a change in control of PPG, an executive must be terminated (or have a substantial diminution of job duties) to be entitled to full vesting acceleration of unvested stock options, TSR awards and restricted stock units. The table below reflects the calculation of the aggregate dollar values related to acceleration of vesting of the incentive equity awards held by the executive officers named in the Summary Compensation Table in the event of a termination following a change in control, and the total is reflected in the "Accelerated Vesting of LTI" row for each officer in the table above on page 52. The stock option value was calculated by multiplying the number of unvested shares by the difference between the grant price and the closing stock price on December 30, 2016 ($94.76). If any stock options were underwater as of December 31, 2016, no value was assigned to such options. The TSR share and restricted stock unit value was calculated by multiplying the target number of unvested shares by the closing stock price on December 30, 2016, except as otherwise noted.

PROPOSAL 2: Advisory Vote on Approval of the Compensation of the Named Executive Officers

Section 14A of the Securities Exchange Act of 1934, as amended, requires that we include in this Proxy Statement a non-binding, advisory shareholder vote on our executive compensation as described in this Proxy Statement (commonly referred to as "say-on-pay"). Based upon the vote of our shareholders at the 2011 annual meeting and the Board's recommendation, PPG has provided this advisory vote on an annual basis. In Proposal 3, shareholders will have the opportunity to vote on whether they prefer that this vote continue to be held on annual basis or whether it should instead be held every two or three years.

We encourage shareholders to review the section of this Proxy Statement relating to executive compensation on pages 24 through 53. Executive compensation is based on our pay-for-performance philosophy, which emphasizes executive performance measures that correlate closely with the achievement of both shorter-term performance objectives and longer-term shareholder value. To this end, a substantial portion of our executives' annual and long-term compensation is performance-based, with the payment being contingent on the achievement of performance goals. We believe our program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our executives to dedicate themselves fully to value creation for our shareholders. This balance is evidenced by the following:

•

In 2016, the Company delivered strong financial performance through a sharp focus on cost management and sales volume growth and despite the persistent, unfavorable impact of weaker foreign currencies and modest and uneven global economic growth. Total net sales from continuing operations for 2016 were consistent with 2015, despite unfavorable currency translation of 3%. The Company's 2016 full-year reported net income from continuing operations was $564 million, or $2.11 per diluted share, versus $1.34 billion, or $4.89 per diluted share, in 2015. Adjusted net income from continuing operations for 2016 was $1.55 billion, versus $1.49 billion in 2015. Full-year adjusted earnings-per-diluted share from continuing operations was $5.82, up 7% year-over-year.

•

In April, the Company raised the per-share dividend by 11%—paying approximately $415 million in dividends in 2016. The Company also repurchased approximately $1.05 billion of stock in 2016.

•

In 2016, the Company completed several acquisitions, increasing both geographic and product scope. In addition, the Company divested several businesses, including the flat glass business, the European fiber glass business and the Company's ownership interests in two Asian fiber glass joint ventures.

The following charts contain adjusted earnings-per-diluted share from continuing operations, net sales from continuing operations and adjusted net income from continuing operations for each of the last five fiscal years:

Adjusted earnings-per-diluted share from continuing operations and adjusted net income from continuing operations are not recognized financial measures determined in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and should not be considered a substitute for earnings-per-diluted share or net income or other financial measures as computed in accordance with U.S. GAAP. PPG's management considers this information useful in providing insight into the company's ongoing operating performance because it excludes the impact of items that cannot reasonably be expected to recur on a quarterly basis or that are not attributable to our primary operations. A Regulation G reconciliation of adjusted earnings-per-diluted share from continuing operations and adjusted net income from continuing operations to reported earnings-per-diluted share from continuing operations and net income from continuing operations is included in Annex A to this Proxy Statement.

•

Consistent with our performance in 2016, annual incentive awards were paid to executive officers ranging from 126% to 159% of target. Our total shareholder return over the past three years when measured against the S&P 500 was in the 36th percentile resulting in the payment of long-term TSR share awards at 42.9% of target.

•

Between 65% and 89% of the named executive officers' target total direct compensation opportunity for 2016 was in the form of performance-based variable compensation and long-term incentives motivating them to deliver strong business performance and create shareholder value.

•

Base salary and annual incentive targets for our executive officers are established annually to maintain parity with the competitive market for executives in comparable positions. Target total annual compensation for each position is set at or near the market median.

•

PPG's compensation programs are reviewed annually to identify any inherent material risks to PPG created by these programs. Based on the results of the 2016 review, we concluded that the design of our compensation programs does not encourage our employees to take unnecessary or excessive risks that could harm the long-term value of PPG.

•

At the 2016 annual meeting, we held a shareholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our shareholders overwhelmingly approved the compensation of our named executive officers, with approximately 97% of shareholder votes cast in favor of our 2016 say-on-pay resolution. Following its review of this vote, the Officers—Directors Compensation Committee recommended to the full Board that we retain our general approach to executive compensation, with an emphasis on short- and long-term incentive compensation that rewards our executive officers when they deliver value for our shareholders. Consistent with this philosophy:

•

Our performance metrics are focused on increasing shareholder value and are tied to measures impacting both shorter-term and longer-term performance. Shorter-term performance metrics include adjusted earnings-per-diluted share from continuing operations, cash flow from operating activities–continuing operations, pre-tax, pre-interest income, working capital reduction, and sales volume/mix growth. Longer-term performance metrics include total shareholder return, adjusted earnings-per-diluted share growth, cash flow return on capital and stock price appreciation.

•

Payment of long-term incentive awards is based solely on Company performance. We have three-year award and payout cycles for both performance-based restricted stock units, or PBRSUs, and total shareholder return shares, or TSR shares. We also have three-year vesting for stock options.

•

We provide very limited perquisites to our executive officers.

•

Our officers are subject to stock ownership requirements. Our Chief Executive Officer must own shares of PPG common stock with a value of six times his base salary, and the other executive officers must own shares of PPG common stock with a value of three times his or her salary. Officers are expected to meet these ownership requirements within five years of election. Those officers who have not yet met this requirement are paid 20% of their annual incentive in PPG stock, which is restricted from sale for a period of two to five years. In addition, for officers who have been subject to the policy for more than five years at their current requirement level and have not met the ownership requirement, 100% of the vested shares delivered from the PBRSU award and TSR share award must be held by the officer for a minimum of one year and until the requirement is met. All executive officers named in the Summary Compensation Table have met their ownership requirement, except for Mr. Sklarsky who was within his five-year compliance period at the time of his retirement.

•

Our officers may not engage in transactions that are contrary to the interests of shareholders, such as "short sales," "short sales against the box," "put" and "call" options and hedging transactions designed to minimize an executive's risk inherent in owning PPG stock. In addition, officers may not hold PPG stock in a margin account and may not pledge PPG stock as collateral for a loan.

•

Executive officers are subject to a "clawback" policy that is designed to recoup incentive compensation when a financial restatement occurs and certain other conditions exist.

•

We do not provide tax gross-ups on perquisites to our named executive officers.

Accordingly, you are asked to vote on the following resolution:

RESOLVED:    The Board strongly endorses the Company's executive compensation program and recommends that the shareholders vote in favor of the following resolution: that the shareholders approve the compensation of the Company's named executive officers as described in this Proxy Statement on pages 24 through 53 and disclosed in

​

​

Table of Contents

accordance with rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis and the tabular and narrative disclosure contained therein.

Because the vote is advisory, it will not be binding upon the Board or the Officers—Directors Compensation Committee, and neither the Board nor the Officers—Directors Compensation Committee will be required to take any action as a result of the outcome of the vote on this proposal. However, the Officers—Directors Compensation Committee will carefully consider the outcome of the vote when considering future executive compensation programs.

Vote Required

Adoption of the resolution approving the compensation of the Company's named executive officers will require the affirmative vote of more than one-half of the shares present, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting.

PROPOSAL 3: Advisory Vote on the Frequency of Future Advisory Votes on Executive Compensation

The Dodd-Frank Wall Street Reform and Consumer Protection Act requires that we include in this Proxy Statement the advisory vote on executive compensation (known as "say-on-pay") appearing in Proposal 2. In addition, the Dodd-Frank Act requires that companies provide their shareholders with a separate non-binding shareholder vote every six years to advise the Board on whether the say-on-pay vote should occur every one, two or three years. You have the option to vote for any one of the three options or to abstain on the matter.

In 2011, the Company held first its first say-on-pay vote. In connection with that vote, the Company asked its shareholders to recommend the frequency of future say-on-pay votes. At that time, the Board recommended and shareholders ageed that PPG should hold a say-on-pay vote annually. In keeping with that recommendation, the Company has held a say-on-pay vote annually. Since 2017 marks the sixth year since the last shareholder recommendation, the Company is required to ask its shareholders again to recommend the frequency of future say-on-pay votes. As it did in 2011, the Board has determined that an advisory vote on executive compensation every year is the best approach for the Company based on a number of considerations. An annual advisory vote on the compensation of our named executive officers allows us to obtain information on shareholders' views of the compensation of our named executive officers on a more consistent basis. In addition, an annual advisory vote on the compensation of our named executive officers aligns more closely with our objective to engage in regular dialogue with our shareholders on corporate governance matters, including our executive compensation philosophy, policies and programs. We understand that our shareholders may have different views as to what is the best approach for PPG, and we look forward to hearing from our shareholders on this proposal.

The proxy card provides shareholders with the opportunity to choose among four options (holding the vote every one, two or three years, or abstaining) and, therefore, shareholders will not be voting to approve or disapprove the Board's recommendation.

Although this advisory vote regarding the frequency of say-on-pay votes is non-binding on the Board, the Board and the Officers-Directors Compensation Committee will review the voting results and take them into consideration when making a determination concerning the frequency of advisory votes on executive compensation.

Vote Required

The frequency of the advisory vote on executive compensation (every one, two or three years) receiving a plurality of the votes cast, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting will be considered the frequency recommended by the Company's shareholders.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Service Fees Paid to the Independent Registered Public Accounting Firm

During 2015 and 2016, we retained PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm. In 2015 and 2016, PricewaterhouseCoopers LLP provided services in the following categories and amounts:

The majority of services performed by PricewaterhouseCoopers LLP in 2016 were pre-approved in accordance with the Audit Committee pre-approval policy and procedures at its February 17, 2016 meeting. Additional services were approved during the year as needed, in accordance with this policy. In so doing, the committee determined that the provision of these services is compatible with maintaining the principal accountant's independence. In 2016, no services (which pursuant to Securities and Exchange Commission regulations were considered de minimis) were provided by PricewaterhouseCoopers LLP that were approved by the committee after such services were performed.

Audit Committee Pre-approval Policy

The pre-approval policy describes the permitted audit, audit-related, tax and other services that PricewaterhouseCoopers LLP may perform and lists a range of fees for these services (referred to as the Service List). The service and fee ranges listed in the pre-approval policy are pre-approved by the Audit Committee. If a type of service to be provided by PricewaterhouseCoopers LLP is not included in the Service List, the committee must specifically pre-approve it. Normally, pre-approval is provided at regularly scheduled meetings. However, the authority to pre-approve up to $150,000 per engagement has been delegated to the committee chair to accommodate time sensitive service proposals. Any pre-approval decisions made by the chair must be communicated to the full committee at the next scheduled meeting.

PROPOSAL 4: Ratification of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors has appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2017. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting and, while they do not plan to make a statement (although they will have the opportunity if they desire to do so), they will be available to respond to appropriate questions from shareholders.

It is intended that the shares represented by each proxy will be voted, in the discretion of the persons appointed as proxies, FOR the ratification. If the selection of PricewaterhouseCoopers LLP is not ratified, the Audit Committee will reconsider the appointment of the Company's independent registered public accounting firm. Even if the selection of PricewaterhouseCoopers LLP is ratified by our shareholders, the Audit Committee in its discretion could decide to terminate the engagement of PricewaterhouseCoopers LLP and engage another firm if the committee determines such action to be necessary or desirable.

Vote Required

The ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2017 will require the affirmative vote of more than one-half of the shares present, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting.

The Annual Meeting will be held on Thursday, April 20, 2017, at 11:00 a.m., Eastern Time, at the Fairmont Pittsburgh, Grand Ballroom, 510 Market Street, Pittsburgh, Pennsylvania 15222.

If I cannot attend the Annual Meeting, can I listen to a webcast of the Meeting?

A listen-only webcast of the Annual Meeting will be available only to PPG shareholders at www.virtualshareholdermeeting.com/PPG2017. You will need your control number included in your proxy card or Notice of Annual Meeting of Shareholders to access the webcast.

Why am I receiving these proxy materials?

In connection with the solicitation of proxies by our Board of Directors to be voted at the 2017 Annual Meeting of Shareholders, these materials have been made available to you on the Internet or, upon your request or under certain other circumstances, have been delivered to you by mail in printed form.

If your shares were registered directly in your name with our transfer agent, Computershare Investor Services, as of the close of business on February 17, 2017, you are considered a shareholder of record, and we have sent you these proxy materials.

If your shares were held in the name of a bank, brokerage account or other nominee as of the close of business on February 17, 2017, you are considered a beneficial owner of the shares held in street name. Your bank, broker or other nominee has sent you these proxy materials. You should direct your bank, broker or other nominee on how to vote your shares, and we encourage you to make such direction. If you do not make a direction with respect to Proposals 1, 2 or 3 your bank, broker or other nominee will not be able to vote your shares on your behalf with respect to such proposals.

What is included in these materials?

These proxy materials include:

•

Our Notice of Annual Meeting and Proxy Statement for the 2017 Annual Meeting; and

•

Our 2016 Annual Report to shareholders, which includes our audited consolidated financial statements.

If you received printed versions of these materials by mail, these materials also include the proxy card or vote instruction form for the Annual Meeting.

Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of printed proxy materials?

In accordance with the rules of the Securities and Exchange Commission, instead of mailing a printed copy of our proxy materials to our shareholders, we have elected to furnish these materials by providing access to these documents over the Internet. Accordingly, on or about March 9, 2017, we sent a Notice of Internet Availability of Proxy Materials ("Notice of Internet Availability") to our shareholders of record and beneficial owners. All shareholders have the ability to access the proxy materials on a website referred to in the Notice of Internet Availability.

What does it mean if I receive more than one set of proxy materials?

It means you have multiple accounts at the transfer agent or with banks, brokers or other nominees. If you received more than one Notice of Internet Availability, you may need to enter separate electronic control voting numbers when voting by the Internet to ensure that all of your shares have been voted. If you received more than one proxy card or vote instruction form, please complete and provide your voting instructions for all proxy cards and vote instruction forms that you receive.

•

Proposal 2: More than one-half of the shares present, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting must vote for the proposal for it to be adopted. The advisory vote on this proposal is nonbinding. However, the Board of Directors will take into account the outcome of the vote on this proposal when making future decisions about the Company's executive compensation arrangements, policies and procedures. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

•

Proposal 3: The frequency of the advisory vote on executive compensation (every one, two or three years) receiving a plurality of the votes cast, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting will be considered the frequency recommended by the Company's shareholders.

However, the Board and the compensation committee will review the voting results and take them into consideration when making a determination concerning the frequency of advisory votes on executive compensation.

•

Proposal 4: More than one-half of the shares present, either in person or by proxy, and entitled to vote and voting (excluding abstentions) at the Annual Meeting must vote for the proposal for it to be adopted.

How do I vote?

You may vote your shares by any one of the following methods:

•

By Internet: Log onto the website indicated in the Notice of Internet Availability or on the proxy card or vote instruction form.

•

By telephone: Call the toll-free number shown on the proxy card or vote instruction form and follow the voice prompts.

•

By mail: Mark your votes, sign and return the proxy card or vote instruction form in the postage-paid envelope provided.

•

By ballot: Attend the Annual Meeting in person and use a ballot to cast your vote.

If you vote by the Internet or by telephone, you do not need to send in a proxy card or vote instruction form. The deadline for Internet and telephone voting will be 11:59 p.m., Eastern Time, on April 19, 2017. If your shares are held in the name of a bank, broker or other nominee, and you wish to vote your shares in person at the Annual Meeting, you will need to contact your bank, broker or other nominee to obtain a legal proxy form that you must bring with you to the Meeting to exchange for a ballot.

What happens if I do not give specific voting instructions?

The Board of Directors is asking for your proxy. Giving us your proxy means that you authorize us to vote your shares at the Annual Meeting in the manner you direct. If you (1) choose the "submit your vote" option without voting on each individual proposal when voting on the Internet or by telephone or (2) if you are a shareholder of record and sign and return a proxy card without giving specific voting instructions, then your shares will be voted in the manner recommended by our Board on all matters presented in this Proxy Statement.

If your shares are held by a broker, bank or other nominee, the broker, bank or nominee will ask you how you want to vote your shares. If you give the broker, bank or nominee instructions, your shares will be voted as you direct. If you do not give instructions, your broker, bank or nominee may vote your shares in its discretion for the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2017 (Proposal 4), but your broker, bank or nominee will not vote your shares at all with respect to any of the other proposals. We encourage you to provide instructions to your bank, broker or nominee by carefully following the instructions provided. This will ensure that your shares are voted at the Annual Meeting as you direct.

How can I change or revoke my vote after I have voted?

You have the right to change your vote or revoke your proxy before it is exercised at the Annual Meeting. You may vote again on a later date on the Internet or by telephone (only your latest Internet or telephone proxy submitted prior to the Annual Meeting will be counted), by signing and returning a new proxy card or vote instruction form with a later date, or by attending the Meeting and voting in person. However, your attendance at the Annual Meeting will not automatically revoke your proxy unless you vote again at the Meeting or specifically request in writing that your prior proxy be revoked. Please note that any re-votes by mail or proxy revocations must be received by our corporate

OTHER INFORMATION

Householding Information

PPG and some banks, brokers and other nominees are participating in the practice of "householding" proxy materials. This means that shareholders who share the same address may not receive separate copies of proxy materials, unless we have received instructions to the contrary. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate set of the proxy materials, or if you are receiving multiple copies of the proxy materials and wish to receive only one, please notify your bank, broker or other nominee if your shares are held in a brokerage account or us if you hold registered shares. We will promptly deliver an additional copy of the proxy materials to you, without charge, if you write to Investor Relations at PPG Industries, Inc., One PPG Place, 40th Floor, Pittsburgh, Pennsylvania 15272, or call us at (412) 434-3318.

It is intended, however, that the proxies solicited hereby will be voted on any other matters that may properly come before the Annual Meeting, or any adjournment thereof, in the discretion of the person or persons voting such proxies unless the shareholder has indicated on the proxy card that the shares represented thereby are not to be voted on such other matters.

ANNEX A
RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

PPG believes investors' understanding of the Company's operating performance is enhanced by the disclosure of net income from continuing operations and earnings per diluted share from continuing operations adjusted for nonrecurring charges. PPG's management considers this information useful in providing insight into the Company's ongoing operating performance because it excludes the impact of items that cannot reasonably be expected to recur on an ongoing basis or that are not attributable to our primary operations. Net income from continuing operations and earnings per diluted share from continuing operations adjusted for these items are not recognized financial measures determined in accordance with U.S. generally accepted accounting principles (GAAP) and should not be considered a substitute for net income from continuing operations and earnings per diluted share from continuing operations or other financial measures as computed in accordance with U.S. GAAP. In addition, net income from continuing operations and earnings per diluted share from continuing operations may not be comparable to similarly titled measures as reported by other companies.

Net income from continuing operations (attributable to PPG) and earnings per share from continuing operations—assuming dilution (attributable to PPG) are reconciled to adjusted net income from continuing operations (attributable to PPG) and adjusted earnings per share from continuing operations—assuming dilution below:
