You are cordially invited to attend the Annual Meeting of Stockholders (Annual Meeting) of Boston Scientific Corporation (the Company) to be held on Thursday, May 6, 2021, at 8:00 a.m. Eastern Time. In light of the ongoing public health crisis caused by the COVID-19 pandemic, the Annual Meeting will be held in a virtual format only, via live webcast over the internet. You will be able to join the Annual Meeting and vote and submit your questions online during the Annual Meeting by visiting https://www.virtualshareholdermeeting.com/BSX2021. We have designed the virtual Annual Meeting to ensure that stockholders are afforded the same opportunity to participate as they would have at an in-person meeting, including the right to vote and ask questions through the virtual meeting platform. Reference to "in person" attendance or voting in our proxy materials refers, therefore, to attending or voting at the Annual Meeting virtually.

These matters are more fully described in the accompanying Notice of Annual Meeting and Proxy Statement. Our Board of Directors urges you to read the accompanying Proxy Statement and recommends that you vote "FOR" all of the director nominees, the named executive officer compensation, and the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm and "AGAINST" the stockholder proposal described in this Proxy Statement. At the meeting, you will be provided with the opportunity to ask questions.

On or about March 24, 2021, we will mail to our stockholders of record at the close of business on Friday, March 12, 2021, the record date for our Annual Meeting, an Important Notice of Internet Availability of Proxy Materials (Notice) containing instructions on how to access our Proxy Statement and Annual Report for the year ended December 31, 2020 (Annual Report) on the Internet and also how to vote their shares via the Internet. If you received a Notice by mail, you will not receive printed proxy materials unless you specifically request them. Both the Notice and the Proxy Statement contain instructions on how you can request a paper copy of the Proxy Statement and Annual Report.

The Board of Directors appreciates and encourages stockholder participation in the Company's affairs. Whether or not you plan to virtually attend the Annual Meeting, we encourage you to vote your shares. Accordingly, we request that as soon as possible, you vote via the Internet or, if you have received printed proxy materials, you vote via the Internet, by telephone or by mailing your completed proxy card or voter instruction form.

Michael F. Mahoney
Chairman of the Board of Directors
President and Chief Executive Officer

The Annual Meeting of Stockholders of Boston Scientific Corporation (Annual Meeting) will be held on Thursday, May 6, 2021, at 8:00 a.m. Eastern Time. In light of the ongoing public health crisis caused by the COVID-19 pandemic, the Annual Meeting will be held in a virtual format only, via live webcast over the internet. You will be able to join the Annual Meeting and vote and submit your questions online during the Annual Meeting by visiting https://www.virtualshareholdermeeting.com/BSX2021. We have designed the virtual Annual Meeting to ensure that stockholders are afforded the same opportunity to participate as they would have at an in-person meeting, including the right to vote and ask questions through the virtual meeting platform. Reference to "in person" attendance or voting in our proxy materials refers, therefore, to attending or voting at the Annual Meeting virtually. The Annual Meeting will take place for the following purposes:

Only stockholders of record at the close of business on Friday, March 12, 2021, are entitled to notice of and to vote at the meeting or any adjournments or postponements thereof.

It is important that your shares be represented and voted at the Annual Meeting. Whether or not you plan to attend the Annual Meeting in person, we encourage you to submit your proxy as soon as possible. For specific instructions, please refer to your Important Notice of Internet Availability of Proxy Materials or to the question on page 9 of the accompanying Proxy Statement entitled "How do I vote by proxy?"

At this meeting, stockholders will be asked to elect nine nominees for director, approve, on a non-binding, advisory basis, named executive officer compensation, ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2021 fiscal year, and consider and vote upon a stockholder proposal described in this Proxy Statement, if properly presented at the Annual Meeting. Management will also respond to questions from stockholders. Our principal executive offices are located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752, and our telephone number is (508) 683-4000. When used in this Proxy Statement, the terms "we," "us," "our," "Boston Scientific" and "the Company" mean Boston Scientific Corporation and its businesses and subsidiaries.

In connection with its solicitation of proxies for use at our Annual Meeting, our Board of Directors (Board) (i) has made these materials available to you via the Internet or, upon your request, via email, or (ii) upon your request, has delivered or will deliver printed versions of these materials to you by mail. As a stockholder of record of our common stock at the close of business on March 12, 2021, the record date for our Annual Meeting, you are invited to attend the virtual Annual Meeting, and are entitled to and requested to vote on the items of business described in this Proxy Statement.

We believe that a virtual meeting will provide expanded stockholder access and participation, improved communications, as well as additional safeguards for health and safety in light of

developments related to COVID-19. You will be able to join the Annual Meeting and vote and submit questions online during the Annual Meeting by visiting https://www.virtualshareholdermeeting.com/BSX2021 and using the 16-digit control number included on the Important Notice of Internet Availability of Proxy Materials (Notice), on your proxy card, or on your voting instruction form provided by your broker, bank or other nominee. Online check-in will be available at the virtual meeting site approximately 15 minutes prior to the beginning of the Annual Meeting.

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

Pursuant to rules adopted by the Securities and Exchange Commission (SEC), we are making this Proxy Statement and our Annual Report for the year ended December 31, 2020 (Annual Report and, together with this Proxy Statement, the proxy materials) available to stockholders electronically via the Internet. Stockholders will be able to access the proxy materials on the website referred to in the Notice or request to receive printed copies of the proxy materials and a proxy card. Instructions on how to access the proxy materials via the Internet or to request a printed copy may be found in the Notice and in this Proxy Statement. We believe that this electronic process expedites your receipt of the proxy materials and reduces the cost and environmental impact of printing proxy materials for our Annual Meeting.

On or about March 24, 2021, stockholders of record and beneficial owners of our common stock at the close of business on March 12, 2021 will be sent a Notice instructing them as to how to receive their proxy materials via the Internet. The proxy materials will be available on the Internet as of March 24, 2021.

Beginning March 24, 2021, you can access the proxy materials and vote your shares online at www.proxyvote.com. The proxy materials are also available on our own website (www.bostonscientific.com).

If you prefer to receive paper copies of the proxy materials and a proxy card, you may still do so. You may request printed materials by (i) calling (800) 579-1639; (ii) sending an email to sendmaterial@proxyvote.com; or (iii) logging onto www.proxyvote.com using the credentials provided on your Notice or proxy card.

Stockholders who held shares of our common stock at the close of business on Friday, March 12, 2021, are entitled to vote at the Annual Meeting. Each share of our common stock is entitled to one vote.

How many shares are eligible to be voted and how many shares are required to hold the Annual Meeting?

A quorum is required to hold the Annual Meeting and conduct business. The presence at the Annual Meeting, in person or by proxy, of stockholders holding a majority of our common stock outstanding as of the close of business on Friday, March 12, 2021, the record date, will constitute a quorum for

purposes of holding and conducting business at the Annual Meeting. As of March 12, 2021, we had 1,420,516,801 shares of our common stock outstanding — each entitled to one vote at the Annual Meeting — meaning that 710,258,401 shares of common stock must be represented in person or by proxy to have a quorum. Our common stock is our only outstanding class of voting securities. For purposes of determining whether a quorum exists, broker non-votes (as described further below) and proxies received but marked "ABSTAIN" will be counted.

Your vote is very important. Whether or not you plan to attend the virtual Annual Meeting, you may give a proxy to be voted at the Annual Meeting either:

If you vote by mail, no postage is required if your proxy card is mailed in the United States. If you properly vote pursuant to the instructions provided in the Notice or properly complete and deliver your proxy card (whether electronically, by mail or by telephone) and our Inspector of Election receives your instructions in time to vote at the Annual Meeting, your "proxy" (one of the individuals

named on your proxy card) will vote your shares as you have directed. If you sign and return your proxy card, but do not make specific selections, your proxy will vote your shares as recommended by the Board. If any other matter is properly presented at the Annual Meeting, including a proposal to postpone or adjourn the meeting, your proxy will vote your shares in accordance with his or her discretion. At present, the Board knows of no other business that is intended to be brought before or acted upon at the Annual Meeting.

What if I need assistance with voting or have questions regarding the Annual Meeting?

If you need assistance with the voting of your shares or have questions regarding the Annual Meeting, please contact our proxy solicitation advisor:

If you have technical difficulties accessing or using the virtual meeting site during the Annual Meeting, you should call the technical support number on the virtual meeting site. The virtual meeting site is supported on browsers (e.g., Internet Explorer, Firefox, Chrome and Safari) and devices (desktops, laptops, tablets and cell phones) running the most updated version of applicable software and plug-ins. Each participant should ensure strong Wi-Fi or other internet connection.

In the election of directors, your vote may be cast "FOR" one or more of the nominees or your vote may be "WITHHELD" with respect to one or more of the nominees. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the advisory vote to approve named executive officer compensation, your vote may be cast "FOR" or "AGAINST" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted and will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, your vote may be cast "FOR" or "AGAINST" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted and will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the stockholder proposal described in this Proxy Statement, your vote may be cast "FOR" or "AGAINST" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted with respect to determining if a majority vote is obtained under our By-Laws and will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

At present, the Board knows of no other matters to be presented for stockholder action at the Annual Meeting.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Most of our stockholders hold their shares through a broker, trustee, bank, other financial intermediary or other nominee rather than directly in their own name. As summarized below, there are some differences between stockholders of record and beneficial owners.

If your shares are registered directly in your name with our transfer agent, Computershare Shareowner Services, as of the close of business on Friday, March 12, 2021, you are considered the stockholder of record with respect to those shares, and the Notice or proxy materials are being made available, electronically or otherwise, directly to you by the Company. As the stockholder of record, you have the right to grant your voting proxy directly to the Company or a third party, or to vote in person at the Annual Meeting. The Company has made available a proxy card or electronic voting means for you to use for voting purposes.

If your shares are held through a brokerage firm, trustee, bank, other financial intermediary or other nominee, as of the close of business on Friday, March 12, 2021, you are considered the beneficial owner of those shares held in street name, and the Notice or proxy materials are being made available, electronically or otherwise, by the Company to your broker, trustee, bank, other financial intermediary or other nominee (the intermediary) and they will forward these materials to you, together with a voting instruction form if furnished via paper copy to your intermediary. As the beneficial owner, you have the right to direct your intermediary on how to vote and are also invited to virtually attend the Annual Meeting; however, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting, unless you request, complete and deliver a legal proxy from your intermediary. If you requested printed proxy materials, your intermediary will enclose a voting instruction form for you to use in directing the intermediary regarding how to vote your shares.

What discretion does my broker have to vote my shares held in "street name?"

The NYSE rules allow your broker to vote your shares in its discretion on "routine" proposals when it has not received instructions from you at least ten days prior to the Annual Meeting. The proposal regarding the ratification of the appointment of our independent registered public accounting firm is a matter considered routine under applicable rules and, therefore, your broker may vote on your behalf for this matter if you do not otherwise provide instructions. The election of directors, the advisory vote on the named executive officer compensation, and the stockholder proposal described in this Proxy Statement are not considered routine matters. If you do not instruct your broker how to vote your shares on the non-routine matters, your broker will not be permitted to vote your shares on such matters. This is referred to as a "broker non-vote."

Broker non-votes (shares held by brokers that do not have discretionary authority to vote on the matter and that have not received voting instructions from their clients) are counted for purposes of determining whether a quorum is present, but are not counted or deemed to be present, represented or voted for the purpose of determining whether stockholders have approved a proposal. A broker non-vote will have no effect on the outcome of the election of directors or the advisory vote on the named executive officer compensation.

If you participate in our 401(k) Retirement Savings Plan, as amended and restated (401(k) Plan), you will receive a single proxy card (together with the proxy materials) or Notice that covers all shares credited to your plan account(s) and shares that you own of record that are registered in the same name. If your plan account(s) are registered in different names, you will receive separate proxy cards or Notices for your record and plan holdings. You may vote your shares by following the instructions

provided in your proxy card or Notice and utilizing the credentials provided therein. Your vote will serve to instruct the trustees and fiduciaries of our 401(k) Plan how to vote any shares of our common stock held in our 401(k) Plan on your behalf. Shares of our common stock held in our 401(k) Plan must be voted on or before 11:59 p.m. Eastern Time on May 1, 2021. The trustee and fiduciaries of our 401(k) Plan will vote shares for which timely instructions are not received in the same proportion as other plan shares that were voted.

What happens if I don't specify how I want my shares voted on one or all of the proposals?

If you are the stockholder of record and you sign, date and return your proxy and do not mark how you want to vote, your proxy will be counted as a vote "FOR" all of the nominees for directors, "FOR" the named executive officer compensation, "FOR" the ratification of our independent registered public accounting firm, Ernst & Young, and "AGAINST" the stockholder proposal described in this Proxy Statement. If you hold your shares in street name, please see the discussion on "What discretion does my broker have to vote my shares held in 'street name?'," above.

Can I change my vote or revoke my proxy after I have already voted or given my proxy?

Yes. If you are a stockholder of record, you may change your vote or revoke your proxy at any time before the proxy is voted at the Annual Meeting. To change your vote, you may:

Your last dated proxy, properly completed and timely received prior to, or vote cast at, the Annual Meeting will be counted.

If you own your shares in street name, please contact your broker or other intermediary for instructions on changing your vote or revoking your proxy.

Yes. If you are the stockholder of record of the shares, you will have the opportunity to vote in person when you attend the virtual Annual Meeting online by visiting https://www.virtualshareholdermeeting.com/BSX2021. In order to vote during the Annual Meeting, you will use the 16-digit control number included on the Notice, on your proxy card, or on your voting instruction form provided by your broker, bank or other nominee. However, since a beneficial owner holding shares in street name is not the stockholder of record, if you are such a beneficial owner of shares, you may not vote your shares in person at the virtual Annual Meeting unless you obtain a legal proxy from the broker or other intermediary that holds your shares giving you the right to vote the shares at the Annual Meeting. Please provide the legal proxy information once you log into the Annual Meeting.

Broadridge has been engaged as our independent agent to tabulate stockholder votes and act as Inspector of Election for the meeting.

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within the Company or to third parties, except:

Occasionally, stockholders provide written comments on their proxy cards, which may be forwarded to the Company's management and the Board.

Your proxy will still be effective and will be voted at the rescheduled Annual Meeting. You will still be able to change or revoke your proxy until it is voted, provided such new proxy or revocation is properly completed and timely received.

Our By-Laws provide that a stockholder may present business to be considered at the Annual Meeting only if proper prior written notice was timely received by us. Other than the items of business described in this Proxy Statement, our Board is not aware of any other business to be acted upon at the Annual Meeting; however, if any other business does properly come before the Annual Meeting, the persons named as proxies on the proxy card will vote your shares in accordance with their discretion.

We will report the final voting results on a Current Report on Form 8-K filed with the SEC within four business days after the Annual Meeting. The Form 8-K will be available on the SEC's website, www.sec.gov, as well as on our own website, www.bostonscientific.com, under the "Investor Relations" section.

A list of stockholders entitled to vote at the Annual Meeting will be available during the Annual Meeting and for ten days prior to the Annual Meeting, between the hours of 8:30 a.m. and 5:00 p.m. Eastern Time, at our Corporate Headquarters located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752. If you would like to view the stockholder list, please contact our Corporate Secretary to schedule an appointment by calling (508) 683-4000 or writing to her at 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

Under rules adopted by the SEC, we are furnishing proxy materials to our stockholders primarily via the Internet instead of mailing printed copies of those materials to each stockholder. On or about March 24, 2021, we will mail to our stockholders (other than those who previously requested electronic or paper delivery) an Important Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including our Proxy Statement and our Annual Report. The Notice also instructs stockholders on how to vote via the Internet.

This process is designed to expedite stockholders' receipt of proxy materials, lower the cost of the Annual Meeting and help conserve natural resources; however, if you would prefer to receive printed proxy materials and a proxy card, please follow the instructions included in the Notice and in this Proxy Statement. If you have previously elected to receive our proxy materials electronically, these materials will continue to be made available to you via email until you elect otherwise. If you have previously elected to receive printed proxy materials, you will continue to receive these materials and a proxy card in paper format until you elect otherwise.

This Proxy Statement contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements may be identified by words like "anticipate," "expect," "project," "believe," "plan," "may," "estimate," "intend" and other similar words. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. Factors that may cause actual results to differ materially from those contemplated by the statements in this Proxy Statement can be found in our most recent Annual Report on Form 10-K filed with the SEC and in the Quarterly Reports on Form 10-Q that we have filed or will file hereafter under the heading "Risk Factors" and "Safe Harbor for Forward-Looking Statements." The forward-looking statements speak only as of the date of this Proxy Statement and undue reliance should not be placed on these statements. We disclaim any intention or obligation to publicly update or revise any forward-looking statements. This cautionary statement is applicable to all forward-looking statements contained in this document.

This Proxy Statement contains statements regarding individual and Company performance objectives and targets. These objectives and targets are disclosed in the limited context of our compensation plans and programs and should not be understood to be statements of management's future expectations or estimates of future results or other guidance. We specifically caution investors not to apply these statements to other contexts.

Our entire Board is elected annually by our stockholders and currently consists of ten members.

On March 9, 2021, Stephen P. MacMillan, a director of Boston Scientific since April 2015, advised us that he would not be standing for re-election to the Board at the Annual Meeting. We are deeply grateful for the enormous contributions that Mr. MacMillan has made to our Company, our Board, and our stockholders.

In light of the departure of one director, nine of our directors have been nominated by our Board, upon the recommendation of our Nominating and Governance Committee, to stand for election at the Annual Meeting for a one-year term, to hold office until the 2022 Annual Meeting of Stockholders and until their successors have been elected and qualified. The nominees for election at the Annual Meeting are: Nelda J. Connors, Charles J. Dockendorff, Yoshiaki Fujimori, Donna A. James, Edward J. Ludwig, Michael F. Mahoney, David J. Roux, John E. Sununu and Ellen M. Zane.

Each of the director nominees is willing and able to stand for election at the Annual Meeting, and we know of no reason why any of the nominees would be unable to serve as a director. Should such a situation arise, however, the Board may designate a substitute nominee or, alternatively, reduce the number of directors to be elected. If a substitute nominee is selected, the persons named as proxies will vote for that substitute nominee. Any vacancies not filled at the Annual Meeting may be filled by the Board.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE ELECTION OF ALL NINE OF THESE NOMINEES FOR DIRECTOR.

To guide the operation and direction of the Board and its committees, our Board has established our Corporate Governance Guidelines, charters for its standing committees and our Code of Conduct to reflect our commitment to good corporate governance and to comply with Delaware law, the rules and listing standards of the NYSE, the rules and regulations of the SEC and other legal requirements. These materials are available under "Governance Overview" in the "Investor Relations" section of our website at www.bostonscientific.com. These materials are also available in print free of charge to stockholders, upon written request to Boston Scientific Corporation, Investor Relations, 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

Our Board believes that good corporate governance is fundamental to the overall success of our business. To that end, our Board evaluates our corporate governance practices in light of applicable changes in Delaware law, the rules and listing standards of the NYSE, the rules and regulations of the SEC, and the rules and regulations under the Internal Revenue Code of 1986, as amended (the Code), as well as best practices suggested by recognized governance authorities, and makes modifications to our corporate governance practices that it determines are warranted.

Under the NYSE's Corporate Governance Standards, a majority of the Board must qualify as independent directors. However, our Corporate Governance Guidelines require that a significant majority of the Board qualify as independent directors. The NYSE Corporate Governance Standards define specific relationships that disqualify directors from being independent and further require that for a director to qualify as independent, the Board must affirmatively determine that the director has no material relationship with our Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with our Company).

In making determinations regarding independence, the Board applies the NYSE standards and broadly considers all relevant facts and circumstances known to it. For directors who will serve on the Compensation Committee, the Board considers all factors specifically relevant to determining whether a director has a relationship with our Company that is material to that director's ability to be independent from management in connection with the duties of a Compensation Committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by our Company to such director, and (ii) whether such director is affiliated with our Company, a subsidiary of our Company or an affiliate of a subsidiary of our Company — as required by the NYSE independence standards for compensation committee members.

The Board has determined that the following directors are independent under the independence standards set forth in the NYSE Corporate Governance Standards: Nelda J. Connors, Charles J. Dockendorff, Yoshiaki Fujimori, Donna A. James, Edward J. Ludwig, Stephen P. MacMillan, David J. Roux, John E. Sununu and Ellen M. Zane.

The Board monitors its compliance with NYSE requirements for director independence on an ongoing basis, including through an annual review of director questionnaires and consideration of transactions and relationships between each director or any member of his or her immediate family and the Company as well as other relevant facts and circumstances. The Board and the Nominating and

Governance Committee considered the directors' responses to a questionnaire asking about their relationships with the Company (and their immediate family members' relationships with the Company) and other potential conflicts of interest, as well as material provided by management related to transactions, relationships or arrangements between the Company and the directors or parties related to the directors. The Board made its determination as to whether any relationship between a director and our Company is a material relationship based on the facts and circumstances of the relationship, the amounts involved in the relationship, the director's interest in such relationship, if any, and such other factors as the Board, in its judgment, deemed appropriate.

The Nominating and Governance Committee is responsible for determining the appropriate skills and characteristics required of new Board members in the context of the current make-up of the Board. In so doing, the Nominating and Governance Committee considers, with input from the Board, those factors it deems appropriate, such as independence, experience, strength of character, judgment, technical skills, diversity, years of experience and the extent to which the individual would fill a present need on the Board. The aim is to assemble a Board that is strong in its collective knowledge and that consists of individuals who bring a variety of complementary attributes and who, taken together, have the appropriate skills and experience to oversee the Company's business. The Nominating and Governance Committee considers diversity as one of a number of factors in identifying nominees for director. The Nominating and Governance Committee views diversity broadly to include diversity of experience, skills and viewpoint, as well as other diversity concepts such as ethnicity and gender. Further, the Board recently adopted an amendment to the Corporate Governance Guidelines that requires that women and racially/ethnically diverse candidates are among the initial slate of candidates presented for consideration in searches for new Board members.

Director nominees must, at a minimum, meet the general criteria outlined in our Corporate Governance Guidelines. Generally, directors should be individuals who have succeeded in their particular field and who demonstrate integrity, reliability, knowledge of corporate affairs and an ability to work well with others, and should also satisfy at least one of the following criteria:

The Nominating and Governance Committee receives suggestions for new directors from a number of sources, including independent Board members and our Chairman and Chief Executive Officer. The Committee may also, at its discretion, employ a third-party search firm to assist in identifying candidates for director.

The Nominating and Governance Committee will also consider recommendations for Board membership submitted by our stockholders and other sources, and considers director nominees for election so submitted if the submission is made in accordance with the advance notice provisions of our By-Laws. The qualifications of candidates recommended by stockholders will be reviewed and considered by the Nominating and Governance Committee with the same degree of care and

consideration as candidates for nomination to the Board submitted by independent Board members and our Chairman and Chief Executive Officer.

Based on engagement with stockholders and benchmarking of corporate governance best practices, the Board amended our By-Laws to add proxy access. Our proxy access By-Law provision permits a stockholder, or group of up to 20 stockholders, meeting certain ownership and other requirements to include a nominee for director election in the Company's Annual Proxy Statement. The Board believes that this change enhances stockholder rights and provides increased accountability of the Company and our Board to our stockholders.

The full Board is responsible for final approval of new director candidates, as well as the nomination of existing directors for re-election. With respect to existing directors, prior to making its recommendation to the full Board, the Nominating and Governance Committee, in consultation with the Chairman of the Board, reviews each director's continuation on the Board as a regular part of the annual nominating process.

Under the advance notice provisions of our By-Laws, director nominations and proposals to bring any other business before the 2022 Annual Meeting of Stockholders by our stockholders must be received by our Corporate Secretary at our principal executive offices on or before November 24, 2021. Under the proxy access by-law provisions of our By-Laws, director nominations submitted for inclusion in our 2022 Annual Proxy Statement must be received no earlier than October 25, 2021 and no later than November 24, 2021. Director nominations by our stockholders must also satisfy the other procedures and requirements set forth in the advance notice and proxy access provisions of our By-Laws, as appropriate. Should you wish to submit a director recommendation or nomination, have it addressed to our Corporate Secretary at Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

The Board has not established any term or age limits to an individual's membership on the Board. While these limits could help ensure that there are fresh ideas and viewpoints available to the Board, they have the disadvantage of causing the Company to lose the contribution of directors who have been able to develop, over a period of time, increasing insight into the Company and its operations and, therefore, provide an increasing contribution to the Board as a whole. The Nominating and Governance Committee, as part of its annual assessment of the composition of the Board, reviews a director's continuation on the Board. The Company believes that, through regular evaluation of

performance and the Company's needs, the Company will continue to achieve the appropriate balance between Boston Scientific experience and fresh ideas and perspectives.

Pursuant to our Corporate Governance Guidelines, the Nominating and Governance Committee reports to the full Board periodically on succession planning for our Chief Executive Officer (and other executive officers, as appropriate). Our Chief Executive Officer discusses with the Board and the Nominating and Governance Committee, at least once per year, his recommendations and evaluations of potential successors to his position, including in the event of an unexpected emergency, and reviews development plans, if any, recommended for such individuals. Additionally, the Nominating and Governance Committee conducts an annual review of the CEO Succession Plan framework, which outlines certain high-level planning, notification and other actions, and is designed to minimize disruption in the event of a temporary or permanent absence of the Chief Executive Officer.

Our Board believes that it is important that it retain flexibility to make the determination as to whether the interests of the Company and our stockholders are best served by having the same individual serve as both Chief Executive Officer and Chairman of the Board or whether the roles should be separated based on the circumstances at any given time. Under our Corporate Governance Guidelines, the Board will appoint a Lead Independent Director when the Chief Executive Officer and Chairman of the Board roles are combined or if the Chairman is not otherwise independent. Pursuant to our Corporate Governance Guidelines, the Lead Independent Director is appointed annually, though is generally expected to serve for a renewable term of three years, subject to annual re-election to the Board. The Lead Independent Director will preside over meetings of our non-management directors, serve as liaison between our Chairman and the independent directors, work with the Chairman to establish agendas for Board and committee meetings, raise issues with management on behalf of the independent directors, consult with committee leadership, and carry out other duties as requested by the Board. The Lead Independent Director also has the authority to call special meetings of independent or non-management directors, as needed.

Mr. Mahoney has been our President and Chief Executive Officer since November 2012 and the Chairman of our Board since May 2016. In light of the fact that the Chief Executive Officer and

Chairman of the Board roles have been combined since May 2016, the Board appointed Mr. Ludwig at that time to serve as Lead Independent Director and re-appointed him to serve in that role for an additional three-year term in February 2019. Mr. Ludwig's qualifications to serve as our Lead Independent Director include his strong leadership experience as Chief Executive Officer and Chairman of the Board of Becton, Dickinson and Company, his service on the Board of CVS Health Corporation and the Chair of that board's Finance Committee, and as lead director on the Board of Aetna, Inc. prior to its acquisition by CVS Health Corporation. Our Board believes that this leadership structure, coupled with a commitment to Board independence, provides effective independent oversight of management, while fostering a constructive and cooperative relationship between the Board and management and allowing both the Board and management to benefit from Mr. Mahoney's day-to-day familiarity with our business operations.

Our Board of Directors conducts annual self-evaluations, overseen by the Nominating and Governance Committee in accordance with the committee's charter. The self-evaluations have been facilitated by a third party and have included in-person and telephonic interviews with directors and presentation of results by the facilitator to our Board and individual directors, as well as written reports to the Board.

Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of our strategic and organizational objectives, to improve long-term organizational performance and to enhance stockholder value. A fundamental part of risk oversight is to understand the individual risks our Company faces, the steps management is taking to manage those risks, including the framework used by management for the coordinated oversight, control and continuous improvement of processes used to manage risk, and to assess management's appetite for risk. It is management's responsibility to manage risk and bring to the Board's attention material risks facing our Company. Our Board receives regular reports from management on matters relating to strategic and operational initiatives, financial performance and legal developments, which are each integrated with enterprise-risk exposures. The involvement of the full Board in approving our strategic plan is a key part of its assessment of the risks inherent in our corporate strategy.

While the Board has the ultimate responsibility for risk oversight, each committee of the Board also oversees risk to the extent that it relates to the committee's responsibilities, as outlined below. Each committee makes reports in its respective area of responsibility to the Board at the next regularly scheduled Board meeting immediately following the committee meeting.

Given the Board's role in risk oversight, it believes that any leadership structure that it adopts must allow it to effectively oversee the management of the risks relating to our operations. Although there are different leadership structures that could allow our Board to oversee risk management effectively, and while our Board believes our current leadership structure will enable it to manage such risks effectively, it was one factor among many considered by our Board in selecting this leadership structure over other potential alternatives. For a discussion of the reasons why our Board has determined that its leadership structure is appropriate, please see the "Board Leadership Structure" above.

Stockholders and other interested parties who wish to communicate directly with any member of our Board, or our non-management directors as a group, may do so by writing to the Board of Directors or Non-Management Directors, Boston Scientific Corporation, c/o General Counsel, 300 Boston Scientific Way, Marlborough, Massachusetts 01752 or by contacting the Board via email at BSCboardofdirectors@bsci.com or non-management directors at non-managementdirectors@bsci.com. The Board has authorized the office of our General Counsel to review and organize, but not screen, communications from stockholders and other interested parties and deliver them to the Board or non-management directors, as applicable. We do screen commercial solicitations for appropriateness.

The Company is committed to stockholder engagement. In addition to the communication process detailed above, stockholders also have the opportunity to speak at our Annual Meeting of Stockholders, participate in the annual "say-on-pay" advisory vote and communicate with our active Investor Relations department, among other avenues for engagement. The Board seriously considers the views of stockholders in its decision-making process. For example, based on engagement with our stockholders and benchmarking of corporate governance best practices, the Board determined that it was in the best interest of the Company and our stockholders to:

The Board values the input of the stockholders who engaged with us on these important matters, and believes that the changes enhance stockholder rights, provide increased accountability of the Company and our Board to our stockholders, and give us an opportunity to further demonstrate our values and commitment to advancing diversity, equity and inclusion.

Without the approval of the Nominating and Governance Committee, no director may sit on more than four public company boards (including our Board) and our Chief Executive Officer may not sit on more than two public company boards (including our Board). No director may serve simultaneously on the audit committees of more than three public companies (including the Company), unless the Board of Directors has determined that such service would not impair the ability of the member to effectively serve on the Company's Audit Committee, such determination to be disclosed in accordance with applicable NYSE or SEC rules. All of our Board members have complied with these limitations or procedures. In accordance with such procedures, the Nominating and Governance Committee and/or Board, as required, has reviewed and approved the following service of our directors:

Our Board has adopted a written related party transaction policy to monitor transactions, arrangements or relationships in which the Company and any of the following have an interest: (i) any person who is or was (since the beginning of 2020, even if they do not presently serve in that role) an executive officer or director or director nominee; (ii) any person or entity who holds more than a 5% beneficial ownership of our common stock; (iii) any immediate family member of any of the foregoing; or (iv) any entity in which any of the foregoing persons is employed or is a general partner or principal or acts in any similar position in which such person or persons collectively have a 10% or greater beneficial ownership interest. The policy covers any related party transaction that meets the minimum threshold for disclosure under relevant SEC rules (generally, transactions involving amounts exceeding $120,000 in which a related person has a direct or indirect material interest).

Related party transaction oversight is the responsibility of our Nominating and Governance Committee. Our General Counsel is responsible for identifying any potential related party transactions and, if she determines that an existing or proposed transaction constitutes a related party transaction under the policy, she will provide relevant details and an analysis of the related party transaction to the Nominating and Governance Committee. The General Counsel provides an annual summary to the Nominating and Governance Committee of all transactions or relationships which she considered under this policy, including those that she determined do not constitute a related party transaction. If the General Counsel has an interest in a potential related party transaction, she will provide all relevant information to the Chairperson of the Nominating and Governance Committee, who will provide the information to the other members of such Committee. The Nominating and Governance Committee reviews relevant information concerning any existing or proposed transaction contemplated by the Company with an entity that is the subject of a disclosed relationship, and approves or rejects the transaction, with or without conditions or additional protections for the Company. Our related party transactions policy can be found in our Corporate Governance Guidelines available under "Governance Overview" in the "Investor Relations" section of our website at www.bostonscientific.com.

Each of the following related party transactions was ratified by the Company's Nominating and Governance Committee at its February 22, 2021 meeting: As part of our Company's commitment to dismantling systemic racism and promoting equality and diversity, the Company announced that it pledged $1 million over four years to support The New Commonwealth Racial Equity and Social Justice Fund (the "Fund"). Desiree Ralls-Morrison, our Senior Vice President, General Counsel and Corporate Secretary, was a founder and serves in the leadership of the Fund. In 2020, the Company made two donations, totaling $750,000 in the aggregate, to the Fund in support of its pledge.

The son of Joseph M. Fitzgerald, our Executive Vice President, Interventional Cardiology, is employed by the Company as a clinical specialist for our Watchman franchise. During 2020, his total compensation, including base salary and commission, was $144,000. His base compensation was commensurate with that of other employees in similar positions within the Company.

The daughter of Edward F. Mackey, our Executive Vice President, Global Operations, is employed by the Company as a manager, regulatory affairs in our Endoscopy business. During 2020, her total

compensation, including base salary, bonus for 2019 paid in 2020, and taxable income from vesting of a prior year equity award was approximately $167,000. Her compensation was commensurate with that of other employees in similar positions within the Company.

We maintain a Code of Conduct, which has been approved by our Board, to ensure that our directors, employees and officers, including our Chief Executive Officer and Chief Financial Officer, understand the basic principles that govern our corporate conduct. The Code of Conduct is available under "Governance Overview" in the "Investor Relations" section of our website at www.bostonscientific.com. A stockholder may request a copy of the Code of Conduct by contacting our Corporate Secretary at Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752. Any waivers or substantive amendments of the Code of Conduct will be disclosed on our website at www.bostonscientific.com.

Sustainability is a key focus of our business. We endeavor to reduce our environmental footprint on a global basis, engage with and support the communities where we operate, conduct our operations in a responsible and ethical manner, advance the growth and capabilities or our employees and develop innovative products that improve health care worldwide. By proactively addressing energy consumption, carbon output, waste management, and water use, we are making measurable progress toward shaping a better future for our planet, which directly impacts the wellbeing of our patients, customers, employees, communities, and investors. Using our Global Energy Management System, we implement our C³ strategy — Cut, Convert, Compensate — to cut energy use, convert to renewable sources instead of fossil fuels, and compensate with carbon offset projects as needed. This strategy helps us make progress towards our goals including using 100% renewable electricity by 2024, 90% renewable energy (all sources) by 2027, and achieving carbon neutrality in manufacturing and key distribution sites for all products by 2030.

For more, please see our sustainability report available at www.bostonscientific.com/performancereport.

The Board met eleven times in 2020. In 2020, each incumbent director attended at least 75% of the aggregate of (1) the total number of meetings of our Board of Directors (held during the period for which he or she has been a director) and (2) the total number of meetings of all committees of our Board of Directors on which the director served (during the periods that he or she served).

Directors are expected to prepare for and use reasonable efforts to participate in all Board meetings and meetings of the committees on which they serve. The Board and each committee will meet as frequently as necessary to properly discharge their responsibilities, provided that the full Board will meet at least four times per year. In addition, directors are expected to use reasonable efforts to attend the Annual Meeting of Stockholders. At our 2020 Annual Meeting of Stockholders, all of our directors were in attendance.

Directors who qualify as independent directors within the meaning of the NYSE Corporate Governance Standards meet in executive sessions without management at every regularly scheduled Board meeting and at such other times as they deem appropriate. Our independent directors meet in executive session at least once annually. In 2020, our independent directors met in executive session without non-independent directors six times. The Chairman of the Board, if independent, or the Lead Independent Director, if the Chairman of the Board is not independent, will preside at executive sessions of independent directors. In his absence, the Chair of the Nominating and Governance Committee presides at these executive sessions, and, in his absence, the Chair of the Audit Committee presides.

Our Board currently has standing Audit, Executive Compensation and Human Resources, Nominating and Governance, and Risk Committees. All of the members of the Audit Committee, Executive Compensation and Human Resources Committee, and Nominating and Governance Committee meet the applicable independence requirements of the NYSE and the SEC. Our Board also establishes special committees from time to time to address specific issues or discrete matters as the need arises.

Each of our standing committees is governed by a written charter, which is subject to annual review by each respective committee and approval by the Board. Committee charters are available under "Governance Overview" in the "Investor Relations" section of our website at www.bostonscientific.com.

Our Audit Committee met ten times in 2020. Our Audit Committee is comprised of Messrs. Dockendorff, Roux and Sununu and Ms. Zane, each of whom meets the independence requirements of the NYSE and the SEC. The Board has also determined that each of Messrs. Dockendorff and Sununu and Ms. Zane is an "audit committee financial expert" as that term is defined in the rules and regulations of the SEC.

As outlined in its written charter, the primary purpose of the Audit Committee is to provide oversight of our accounting and financial reporting processes and audits of our financial statements, as well as of our global compliance program, including matters related to compliance with financial, legal and regulatory requirements. The Audit Committee has responsibility to, among other things:

Our Executive Compensation and Human Resources Committee (Compensation Committee) met five times in 2020. Ms. James, Ms. Connors, and Messrs. Ludwig and MacMillan are the current members of the Compensation Committee. The Compensation Committee is, and was during 2020, comprised exclusively of "independent directors," as defined by the NYSE, including under the heightened independence standards applicable to compensation committee members, "non-employee directors" within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act), and "outside directors" within the meaning of Section 162(m) of the Code.

As outlined in its written charter, the Compensation Committee has the responsibility to, among other things:

The Compensation Committee may delegate its authority and duties to subcommittees or individual members of the Compensation Committee, as it deems appropriate in accordance with applicable laws

and regulations. The Compensation Committee has delegated authority to our Chief Executive Officer to make equity grants to new hires and retention awards to existing employees who are not executive officers within predetermined guidelines. These grants are reviewed with the Compensation Committee at its next regularly scheduled meeting. The Compensation Committee may also delegate authority to make amendments to the Company's benefit plans and Global Employee Stock Ownership Plan to the Senior Vice President, Human Resources, that she determines to be necessary to maintain compliance with applicable law or other technical amendments that do not materially increase the cost of the plans to the Company.

Pursuant to its charter, the Compensation Committee has sole authority to retain or obtain advice from any compensation consultant, legal counsel or other advisor, as the Compensation Committee deems appropriate to assist the Committee in the performance of its duties, including the sole authority to approve the compensation and other terms and conditions of retention. Prior to any such retention, and on an annual basis, the Compensation Committee considers any factors relevant to such consultant's, legal counsel's or advisor's independence from management, including the factors specified in the NYSE Corporate Governance Standards or other listing rules, to evaluate whether the services to be performed will raise any conflict of interest or compromise the independence of such consultant, legal counsel or advisor. Semler Brossy Consulting Group, LLC (Semler Brossy) served as the Compensation Committee's independent compensation consultant in 2020. During 2020, Semler Brossy provided the following compensation services to the Compensation Committee:

For additional information regarding the services provided by Semler Brossy, please see the Compensation Discussion & Analysis section.

In 2020, Semler Brossy and its affiliates did not provide additional services to the Company other than at the request of the Compensation Committee. After review and consultation with Semler Brossy, the Compensation Committee determined that Semler Brossy is independent, and there is no conflict of interest resulting from retaining Semler Brossy currently or during 2020. In reaching these conclusions, the Compensation Committee considered the factors set forth in the SEC rules and the NYSE listing standards.

In accordance with its annual review of its compensation consultant engagement, the Compensation Committee will evaluate the engagement of Semler Brossy in May 2021.

The Compensation Committee Report can be found on page 75 of this Proxy Statement.

The Nominating and Governance Committee met four times in 2020. Messrs. Roux and MacMillan, Ms. James, and Ms. Zane are the current members of the Nominating and Governance Committee, each of whom is a non-employee director and meets the independence requirements of the NYSE.

As outlined in its written charter, the Nominating and Governance Committee has responsibility to, among other things:

The Nominating and Governance Committee is also responsible for reviewing with the Board, on an annual basis, the current size, structure and composition of the Board as a whole, and whether the Company is being well served by the current directors taking into account the following: the directors' degree of independence; business background, including any areas of particular expertise, such as accounting or related financial management expertise, marketing or technology; record of service (for incumbent directors), including attendance record; meeting preparation; overall contribution to the Board; employment status; gender; ethnicity; years of experience; availability for service to us; and our anticipated needs.

For information on the nomination process conducted by the Nominating and Governance Committee and our policies regarding stockholder nominations of directors, please see the Corporate Governance section titled "Director Nomination Process."

The Risk Committee met three times in 2020, beginning with its initial meeting in May 2020. Messrs. Sununu, Dockendorff, and Fujimori and Ms. Connors are the current members of the Risk Committee. As outlined in its written charter, the Risk Committee is charged with providing Board oversight of matters relating to (i) the enterprise-wide approach to risk management, (ii) regulatory compliance, (iii) the quality and safety of our products, and (iv) our insurance program.

In March 2020, our Board determined that it would be in the best interests of the Corporation and our stockholders to dissolve the Finance Committee and create a Risk Committee, effective May 6, 2020. Before May, the Finance Committee met one time in 2020.

The members of our Compensation Committee during 2020 were Ms. Connors, Ms. James, Mr. Ludwig and Mr. MacMillan. None of these Compensation Committee members is or has ever been an officer or employee of our Company. During 2020, no member of the Compensation Committee had a relationship that must be described under the SEC rules relating to disclosure of related person transactions. In 2020, none of our executive officers served on the board of directors or compensation committee (or other board committee performing equivalent functions) of any entity that had one or more of its executive officers serving on the Board or the Compensation Committee of the Company.

The Compensation Committee evaluates the appropriate level and form of compensation for non-employee directors at least annually and recommends changes to our Board when appropriate. Non-employee directors receive a combination of cash and equity compensation for their service on our Board. To determine the level of compensation for 2020, the Compensation Committee relied on the consulting services of Semler Brossy, as well as publicly available data describing director compensation in our peer group companies, to establish an appropriate and competitive level of compensation. The Compensation Committee generally aims to provide a level of compensation that is competitive with the median of peer and other similar companies. The Compensation Committee also took into consideration the significant amount of time and dedication required by our directors to fulfill their duties on our Board and Board committees as well as the need to continue to attract highly qualified candidates to serve on our Board. Our director compensation is as follows:

For their service for the annual term beginning on the date of the 2020 annual meeting of stockholders, the non-employee director compensation program is described below and in the following sections:

In April 2020, in light of the disruption and uncertainty created by the evolving COVID-19 pandemic and its anticipated impact on the Company's operations, the Board of Directors determined that, for the one-year term beginning at the 2020 Annual Meeting of Stockholders, for each non-employee director serving on the Board, the annual cash retainer of $115,000 would be temporarily reduced by 50 percent. In the event that a non-employee director elected to receive equity in lieu of the annual cash retainer, as permitted under the Company's non-employee director compensation program, such grant occurred in the ordinary course in connection with the 2020 Annual Meeting of Stockholders but was reduced in value by 50 percent. Additionally, the fee paid to the Lead Independent Director would be reduced by 50 percent, from $40,000 to $20,000.

On September 30, 2020, the Board determined that, due to stronger business results compared with the Company's prior expectations, the annual cash retainer for the Board and the fee for the Lead Independent Director would be restored, beginning with a payment expected to be made during the fourth quarter of 2020. As a result, the aggregate annual cash retainer for the Board and Lead Independent Director fee were two-thirds, rather than one-half, of the previously approved amounts

for the 2020 term. In the event that a non-employee director elected to receive equity in lieu of the annual cash retainer, an additional grant valued at one-sixth of the annual cash retainer was made at or around the time of the payment of the fourth quarter 2020 Board cash retainer.

The annual equity grants are made on the date of each annual meeting of stockholders. If a non-employee director is appointed to the Board on a date other than the annual meeting of stockholders, an equity grant in an amount equal to the then-current non-employee director annual award, prorated for the time period from the effective date of the appointment to the next annual meeting of stockholders, is made on the first trading day of the month following the month in which the new director was appointed to the Board. Such awards made to new non-employee directors become free from restriction upon the expiration of the new director's current term of office on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term. Additionally, if a non-employee director is appointed to the Board on a date other than the annual meeting of stockholders, the annual cash retainer for such director will be prorated for the time period from the effective date of the appointment to the next annual meeting of stockholders.

Each non-employee director receives the annual cash retainer and fees on a quarterly basis. For 2020, each non-employee director could elect to receive all or a portion of his or her cash compensation as one or both of two equity alternatives, each to vest on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term: (i) restricted stock valued based on the closing price of our common stock on the date of grant; and (ii) deferred stock units, valued based on the closing price of our common stock on the date of grant (with shares of our common stock to be issued only after a director's separation from Board service in accordance with the Boston Scientific Non-Employee Director Deferred Compensation Plan, as amended and restated, effective January 1, 2014 (the 2014 Non-Employee Director Deferred Compensation Plan)). Each non-employee director could also choose to defer receipt of all or a portion of his or her annual cash compensation under the 2014 Non-Employee Director Deferred Compensation Plan, as described further below.

The annual equity grants are made on the date of each annual meeting of stockholders and are subject to the terms and conditions of our 2011 Long-Term Incentive Plan (2011 LTIP). In 2020, each non-employee director could elect to receive his or her annual equity award as one or both of the following two equity compensation alternatives, each to vest on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term: (i) restricted stock valued based on the closing price of our common stock on the date of grant; and (ii) deferred stock units valued based on the closing price of our common stock on the date of grant (with shares of our common stock to be issued only after a director's separation from Board service in accordance with the 2014 Non-Employee Director Deferred Compensation Plan).

At the 2020 Annual Meeting of Stockholders, our stockholders voted to approve an amendment and restatement of the 2011 LTIP, which, among other changes, provided that a reasonable annual limit would be imposed on the cash and equity compensation that may be granted or paid to any non-employee director during a calendar year so that the accounting value of equity awards, when

aggregated with cash compensation, granted to a non-employee director in any calendar year does not exceed $600,000.

Directors who are also employees of the Company receive no compensation for serving on the Board or its committees.

We pay or reimburse our directors for transportation, hotel, meals and other incidental expenses incurred in connection with their performance of services for us, including attending Board and committee meetings and participating in director education programs. Our corporate aircraft is made available to our directors for travel to and from our Board meetings, as well as for certain other Company business travel. We also extend directors' and officers' indemnity insurance coverage to each of our directors.

Each non-employee director may, by written election, defer receipt of all or a portion of the annual cash retainer, annual cash committee chair fees and equity compensation under our 2014 Non-Employee Director Deferred Compensation Plan. Cash amounts deferred can be invested in deemed investment options in which we credit the amount deferred plus any earnings from the chosen investment options. Investment options under the plan are generally the same as those offered under the Company's 401(k) Plan through Vanguard, except that, among other things, directors may not elect to invest in the BSC Stock Fund. Deferred cash amounts are payable, at the non-employee director's written election, in either a lump-sum or in annual installments after a director's separation from Board service or in a lump-sum on an earlier fixed date (in all cases, in accordance with the plan).

We believe the stock ownership requirements for our non-employee directors align the interests of our directors with the long-term interests of our stockholders. Our director stock ownership guidelines provide that each non-employee director should own shares with a value equal to at least five times the director annual cash retainer within five years of joining the Board. For purposes of satisfying this obligation, stock units and stock or stock unit deferrals under a Company deferred compensation plan may be included in the aggregate number of shares held by a director. All of our non-employee directors who have served five years or more currently meet our director stock ownership guidelines. The Nominating and Governance Committee monitors compliance with these guidelines on an annual basis. For information regarding the stock ownership guidelines applicable to our Chairman and Chief Executive Officer, please see the Compensation Discussion & Analysis section titled "Executive Stock Ownership Guidelines."

Please refer to footnotes 1 through 14 above for additional details regarding the holdings of our directors, our director nominees and our Named Executive Officers.

Section 16(a) of the Exchange Act requires our directors, executive officers and persons beneficially holding more than 10% of our common stock to file with the SEC reports of their ownership of our common stock and any changes in that ownership. To our knowledge, all of these filing requirements were timely satisfied in 2020. In making this statement, we have relied upon the written representations of our directors and executive officers and copies of reports that have been filed with the SEC.

This discussion and analysis section describes material elements of our 2020 compensation program for our Named Executive Officers (NEOs), which include our Chief Executive Officer (CEO), our Chief Financial Officer (CFO), and our three other most highly-compensated executive officers. NEOs for the year ended December 31, 2020 were as follows:

During 2020, our management team responded to the challenges presented by the COVID-19 pandemic with swift and decisive actions. First and foremost, we focused on keeping our employees safe, while continuing to support our patients and customers. We effectively managed liquidity and debt, took the decisive action required early in the pandemic to avoid laying off our employees and to be prepared for a strong recovery, and continued to work toward many of our strategic goals, including those relating to product pipeline and digital enablement, as well as key ESG, human capital, and innovation metrics. Ultimately, we believe our response to the challenges of 2020 will enable us to continue to focus on the following five strategic imperatives to help drive innovation, improve the health of patients across the globe, accelerate profitable revenue growth, and increase stockholder value in 2021 and beyond:

We believe that continued focus on these strategic imperatives will benefit patients and customers and lead to strong performance across key financial metrics, including those incorporated into our short-and long-term incentive programs, described in further detail below.

Our short- and long-term incentive plans incorporate metrics designed to align with the objective of driving profitable growth and reward Company and individual progress related to the strategic imperatives. Below is a snapshot of 2020 adjusted financial performance metrics used in our short- and long-term incentive programs, as well as the most directly comparable reported metrics:


(1)		Adjusted net sales, adjusted EPS and adjusted free cash flow are not prepared in accordance with generally accepted accounting principles in the United States (GAAP). For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures and insight into how these non-GAAP measures are considered by management, please see Annex A.
(2)		Adjusted net sales excludes the impact of foreign currency fluctuations. Adjusted EPS excludes the impact of goodwill and intangible asset impairments, acquisition- and divestiture-related net charges, restructuring and restructuring-related net charges, litigation-related net charges, investment impairment charges, EU Medical Device Regulation implementation costs, deferred tax expenses (benefits), discrete tax items, and amortization expense.
(3)		3-year Total Shareholder Return for the period from January 1, 2018 to December 31, 2020. Please see the Executive Compensation section titled "2020 Total Shareholder Return Performance Share Program" for how we calculate Total Shareholder Return.

Our executive compensation philosophy is to provide appropriate competitive compensation opportunities to our executives with actual pay outcomes tied to achievement of Company and individual performance targets in support of our business strategy and creation of long-term stockholder value.

Each year, the Compensation Committee assesses our CEO's actual compensation relative to the Company's performance. The following graph shows the relationship of our CEO's total direct compensation (as disclosed in the Summary Compensation Table) (TDC) compared against our cumulative total shareholder return (TSR) performance in each of the last three years. The TDC in this

chart consists of base salary and annual short- and long-term incentives. As illustrated, CEO compensation was generally aligned with Company performance.

Summary Compensation Table Total Direct Compensation
versus 3-Year Total Shareholder Return(2)


(1)		Amounts in the 2018, 2019, and 2020 columns were calculated as follows:
		• the values of the annual equity awards granted on February 15, 2018, February 21, 2019, and February 18, 2020 were determined in accordance with FASB ASC Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table";
		• the actual Annual Bonus Plan award for 2018, 2019, and 2020; and
		• the annual base salary earned in 2018, 2019, and 2020.
(2)		Total shareholder return was calculated in accordance with the methodology described in the Executive Compensation section titled "2020 Total Shareholder Return Performance Share Program" and based on $100 invested on December 31, 2017.

The following chart shows the value of the primary elements of total direct compensation, consisting of base salary and annual short- and long- term incentives, for our CEO in 2020 (i) at "target" opportunity as considered by our Compensation Committee; (ii) as disclosed in our Summary Compensation Table; and (iii) as "realizable" at December 31, 2020. These values were calculated using the 2020 base salary, annual equity incentives and Annual Bonus Plan ("ABP") award amounts for our CEO as set forth in the table following the chart below.

	Valuation of Compensation Component

	Base Salary	ABP Award	Long-Term Incentives

Target	Annual base salary approved in February 2020	Target 2020 Annual Bonus Plan award	Annual equity awards granted on February 18, 2020, with (a) stock options valued in accordance with FASB ASC Topic 718 and (b) service-based deferred stock units (DSUs) and performance-based DSUs valued at target (the number of units and target units awarded multiplied by the closing price of our common stock on the date of grant).
Summary Compensation Table	Annual base salary earned in 2020	Actual 2020 Annual Bonus Plan award	Annual equity awards granted on February 18, 2020, with the value of each award determined in accordance with FASB ASC Topic 718.
Realizable	Annual base salary earned in 2020	Actual 2020 Annual Bonus Plan award	Annual equity awards granted on February 18, 2020, with: (a) stock options valued at their intrinsic value (number of options awarded multiplied by the closing price of our common stock on December 31, 2020 less the exercise price of such options); (b) service-based DSUs valued using the number of units awarded multiplied by the closing price of our common stock on December 31, 2020; (c) Total Shareholder Return (TSR) performance-based DSUs valued using 0% of the target TSR performance-based DSUs due to the Company's TSR rank being 57^th out of 57, or 0^th percentile (0% of the target number of units multiplied by the closing price of our common stock on December 31, 2020); and (d) the free cash flow (FCF) performance-based DSUs valued using 88.6% of the target FCF performance-based DSUs (the actual percentage of target units earned under the program) multiplied by the closing price of our common stock on December 31, 2020.

The difference in value of the long-term incentive compensation portion of our CEO's TDC reflected in the "Realizable", "Target", and "Summary Compensation Table" columns is primarily due to three factors:

This demonstrates the sensitivity of CEO pay to the achievement of performance criteria, and, therefore, the linkage between our executive compensation program and the long-term interests of our stockholders. The long-term incentive portion of the CEO's compensation will remain "at-risk" and the value will vary until the completion of the vesting periods or until the exercise date for each of the equity awards.

A Significant Portion of our NEOs' 2020 Target TDC is At-Risk, Performance-Based Compensation

Our Compensation Committee ties a significant portion of our executives' target TDC to at-risk, performance-based incentive opportunities. For 2020, approximately 90.8% of the target value of the primary elements of TDC for our CEO and approximately 80.3% of the target value of the primary elements of TDC for our other NEOs as a group consisted of at-risk, performance-based incentive compensation, comprised of short-term incentives (Annual Bonus Plan award) and long-term incentives (performance- and service-based equity awards and stock options). For more details and a breakdown of the elements of TDC, please see the section titled "Elements of 2020 Executive Compensation, Primary Elements of Total Direct Compensation".

The percentages above were calculated using the 2020 base salary, target equity values and target Annual Bonus Plan award amounts for our NEOs. The allocation of the target value of the primary elements of TDC for our CEO and for our other NEOs as a group in 2020 was as follows:

We believe our emphasis on at-risk, performance-based incentive compensation aligns our executives' financial interests with our business strategy and the short- and long-term interests of our stockholders, providing "pay for performance" and putting a significant portion of our executives' pay "at risk."

Our Compensation Committee believes that a strong foundation for our compensation program is necessary to execute our executive compensation philosophy effectively. The following best practices serve as the foundation for our executive compensation program:

At our 2020 Annual Meeting of Stockholders, we asked our stockholders to approve, on an advisory basis, the 2019 compensation of our then-NEOs as disclosed in our 2020 Proxy Statement, commonly referred to as a "say-on-pay" advisory vote. Our stockholders approved the compensation of our then-NEOs with approximately 94.5% of the votes cast voting in favor of the proposal. In connection with its review of our compensation program against our executive compensation philosophy, business objectives and peer group practices, our Compensation Committee considered the prior years' modifications to our compensation programs in support of our executive compensation philosophy and best practices, the results of the say-on-pay advisory vote, as well as prior stockholder feedback. As a result, our Compensation Committee concluded that it would retain the overall structure and design of our compensation program, including its emphasis on at-risk, performance-based incentive compensation.

Our philosophy is to provide appropriate competitive compensation opportunities to our executives such that actual pay outcomes are heavily influenced by achievement of Company, business and individual performance targets and objectives, which are designed to support our business strategy and create long-term stockholder value. The core objectives of our compensation program are to:

Our Compensation Committee bears principal responsibility for, among other things, structuring our executive compensation program and making individual executive compensation determinations. To help facilitate informed determinations with respect to its responsibilities, our Compensation Committee engages an independent compensation consultant, Semler Brossy Consulting Group, LLC (Semler Brossy), which serves at the direction and under the supervision of our Compensation Committee. For further information about our Compensation Committee and the services provided by Semler Brossy, please see the Meetings and Board Committees section titled "Executive Compensation and Human Resources Committee." Semler Brossy and certain members of management support our Compensation Committee with respect to the following, among other things:


Independent Advisor
*Semler Brossy* Advisor to the Compensation Committee		• Expertise-based advice, research and analytical services, including peer group composition, trends and comparative practices in executive compensation, program design and non-employee director compensation. • Commentary and/or recommendations as to the foregoing. • Participation in Compensation Committee meetings.
Management
*Senior Vice President, Human Resources,* and *Total Rewards Management Team*		• Proposals, including regarding compensation and benefits design and pay levels, for executives' employment arrangements for new or promoted executives. • Reporting and advisory on diversity and inclusion topics, including pay equity. • Expertise-based advice, research and analytical services, commentary and/or recommendations as to the foregoing. • Participation in Compensation Committee meetings.
*Chief Executive Officer and other Executives*		• Overview of individual performance of direct reports. • Recommendations as to compensation of direct reports. • With respect to the CEO and General Counsel, participation in Compensation Committee meetings, except for determinations of their own compensation.

Our Compensation Committee uses competitive market analysis as a decision-making reference. The Committee primarily considers executive compensation comparative data for our peer group companies to better understand trends and comparative practices, program design in the market within which we compete for top talent, and competitive levels and mix of target compensation opportunities provided to our executives. Our peer group includes companies (i) operating in a comparable industry with respect to customer base and/or product offerings, such as healthcare equipment and services companies, pharmaceuticals, and biotechnology and life sciences, and (ii) that, in the aggregate, approximate our size as measured by revenue and market capitalization.

Each year, with the assistance of its independent compensation consultant, our Compensation Committee reviews the composition and appropriateness of our peer group. The Committee considers the size, performance, and business focus of these companies in comparison to us. The peer companies used to establish 2020 compensation levels include:

In establishing 2020 pay levels for our NEOs, the Compensation Committee reviewed comparative pay information for the peer group companies through proxy research and survey data as reported in the Equilar, Radford, and Willis Towers Watson surveys. Where peer group information was unavailable, the Committee reviewed industry-specific survey data which was calibrated to include companies

comparable to our size and scope of each individual's responsibilities. The Company considers market data without regard for any particular percentile positioning. This allows us to retain flexibility to make individual decisions that reflect both market and internal considerations, including those described below under "Internal Pay Equity and Other Considerations."

In addition to the competitive market analysis, the Committee considers multiple factors in formulating compensation decisions. These factors include:

In considering internal pay equity, and the elements of an executive officer's TDC opportunity compared to the other executive officers, the Committee also considers CEO compensation relative to the other executive officers. The Committee strives to maintain the appropriate balance in order to motivate the Company's executive team, retain key personnel in a highly competitive labor market, and support a robust succession planning process. The differences between CEO and NEO pay reflect the foregoing factors, as well as the Company's organizational structure.

We utilize a performance, development and coaching (PDC) process to help guide individual development and performance discussions and to assess ongoing performance. Our CEO undertakes regular PDC reviews for all direct reports, assesses the performance results of those direct reports and makes recommendations to our Compensation Committee for its consideration. Our Compensation Committee reviews and evaluates our CEO's performance objectives and oversees the evaluation of his performance in relation to those objectives. For 2020, the overall performance of our executives, including our NEOs, supported a culture of high performance, integrity and accountability with clear expectations. These performance evaluations, among the other considerations described in this section, influence the Compensation Committee's decisions regarding our executives' base salaries, the individual component of their Annual Bonus Plan awards and, as an indication of future performance potential, their long-term equity incentive awards.

The application of CEO and Compensation Committee judgment is an important factor in setting and determining executive pay. We do not employ a purely formulaic approach to our executive compensation program. Target market guidelines and individual target TDC, financial and operational targets, individual performance objectives and funding formulae are established in advance; however, other Company and individual performance and other considerations may also be taken into account. For example, under the 2020 Annual Bonus Plan, while the funding formula tied to Company-level

financial performance targets are set in advance, our Compensation Committee is able to reduce the total Annual Bonus Plan funding percentage (Total Bonus Pool), to not less than 50% of the target, based on (i) its assessment of the Company's progress toward achievement of our quality objectives, which are critical to our commitment to providing high quality products to our customers and patients, or (ii) based on performance against operating income margin targets, which takes into consideration the Company's profitability and commitment to our shareholders, as well as affordability of the proposed bonus funding.

Further, in March 2020, due to the uncertainty around the potential impacts of the COVID-19 pandemic, the Compensation Committee resolved to permit the exercise of discretion in the determination of the 2020 Annual Bonus Plan funding percentage. The Committee anticipated that potentially using discretion at the end of the year to set funding was more prudent than approving multiple revisions of the performance targets, in light of the evolving pandemic. A description of the exercise of discretion in determining the Annual Bonus Plan funding this year is set forth in the section titled "Total Bonus Pool Funded Based on Company Performance."

We compensate our executives primarily through total direct compensation, namely in the form of base salary and short- and long-term incentives (the primary elements of TDC). Our primary elements of TDC are heavily weighted towards variable, at-risk performance-based elements, which are reflected below and in the charts under the section above titled "A Significant Portion of our NEOs' 2020 Target TDC is At-Risk, Performance-Based Compensation." These percentages were calculated using the 2020 base salary, target equity values and target Annual Bonus Plan award amounts for our NEOs set forth in the footnotes to the charts under the section titled "A Significant Portion of our NEOs' 2020 Target TDC is At-Risk, Performance-Based Compensation."

The key features and objectives of the primary elements of our NEOs' 2020 TDC are summarized in the table below.

TDC Elements	Key Features	Objectives


Base Salary	Fixed annual cash amount, paid at regular intervals.	Attract and retain talented executives and provide stable source of income.
Short-Term Incentives — Annual Bonus Plan Awards	At risk, performance-based annual cash incentive opportunity.	Align executive compensation with our business strategy, quality, and profitability objectives.
	—Funding of Total Bonus Pool based on Company performance against two important financial performance targets.	Focus and reward based on the achievement of important financial, operational and individual performance objectives.
	—Allocation of funded Total Bonus Pool, based on regional, business and functional performance against specific financial and/or operational performance targets.
	—Actual payout based on individual performance.
Long-Term Incentives — Equity Awards	At risk, performance-based equity incentive opportunity.	Focus talent/organization on important financial measures and long-term stockholder value.
	Mix of opportunity comprised of:	Reward based on:
	—25% target TSR performance-based DSUs	—our TSR relative to that of other S&P 500 Healthcare Index companies
	—25% target FCF performance-based DSUs	—our adjusted free cash flow measured against our target performance
	—25% stock options	—our stock price increase
	—25% service-based DSUs	—our stock price

In determining the 2020 base salaries of our NEOs (other than our Chief Executive Officer), our Compensation Committee also considered the recommendations of our Chief Executive Officer in light of the general factors discussed above, including their overall performance ratings for the prior year.

The 2020 base salaries (rounded to the nearest thousand) for our NEOs, as well as the percentage increase from their 2019 base salaries for our current NEOs who were also NEOs in 2019, are set forth below.

In April 2020, the Company announced that, in light of the disruption and uncertainty created by the evolving COVID-19 pandemic and its anticipated impact on the Company's operations, all of our Executive Officers, including our NEOs, would take a significant temporary reduction in base salary for up to six months. During this time, Mr. Mahoney took a 99% reduction in his salary and our other NEOs each took a 40% to 50% reduction in their salaries. In August 2020, the Company announced that the base salary reductions for the Company's Executive Officers, other than the Chief Executive Officer, would terminate and revert to previously approved levels. Mr. Mahoney's salary reduction continued until the end of the six-month period, ending in October 2020. For additional disclosure regarding the salaries earned by our NEOs, please see the footnotes to the Executive Compensation section titled "Summary Compensation Table".

Our Compensation Committee annually reviews the design of our Annual Bonus Plan to help ensure that the program continues to support our executive compensation philosophy and core compensation program objectives. In finalizing the design for 2020, our Compensation Committee retained substantially all of the provisions of our 2019 Annual Bonus Plan, which was designed to reinforce the concept of "pay for performance," align our short-term incentives with important financial and operational measures and the long-term interests of our stockholders, and to incentivize and reward individual performance. The Compensation Committee also retained the discretion to reduce the Total Bonus Pool funding percentage, regardless of financial achievements, to 50% of the target, based on its assessment of the Company's achievement of our quality objectives, and based on performance against the operating income margin target. This discretion reinforces our commitment to providing quality products for our customers and patients and takes into consideration the Company's profitability and value creation for our shareholders, as well as affordability of the proposed bonus funding.

Further, in March 2020, due to the uncertainty around the potential impacts of the COVID-19 pandemic, the Compensation Committee resolved to consider the exercise of discretion in its determination of the funding for the 2020 Annual Bonus Plan. In February 2021, after a fulsome review of Company performance, the Committee decided to use discretion in determining 2020 Annual Bonus Plan funding, as is described further below in the section titled "Total Bonus Pool Funded Based on Company Performance."

The 2021 Annual Bonus Plan, which was approved by the Compensation Committee in November 2020, retained many of the same provisions of our 2020 Annual Bonus Plan, however, the Compensation Committee added a human capital scorecard, which will allow management and the Committee to consider progress toward diversity, equity, and inclusion (DE&I), engagement and retention, and ESG goals in addition to retaining important financial and quality/operational measures in making total bonus pool funding decisions. Adding this human capital scorecard underscores the Company's commitment to these goals and will incentivize Company-wide progress in these areas. Further, the 2021 Annual Bonus Plan removes the operating income margin target as a modifier and eliminates the 50% floor for funding.

After funding the Total Bonus Pool, the actual amount of an executive's Annual Bonus Plan award is ultimately determined as follows:

In prior years and, as contemplated under the 2020 Annual Bonus Plan, a single Company-wide Total Bonus Pool is funded by the Company's performance measured against important Company-level financial and operational performance metric targets, thereby reinforcing the importance of the Company's performance as a whole (which reflects the performance of our regions, businesses and functions).

In approving the 2020 Annual Bonus Plan, the Compensation Committee selected Adjusted EPS and Adjusted Net Sales as our Company-level financial metrics and, in March 2020, the Committee approved performance targets as follows:

At that time, our Compensation Committee also approved the Total Bonus Pool funding scale for the Company's 2020 performance measured against our 2020 Company-level performance metric targets

for adjusted EPS and adjusted net sales set forth in the table below. Each metric was expected to have a 50% weighting.

The Committee's approval of these Company-level Annual Bonus Plan performance targets and funding scales was based on an annual operating plan developed with much uncertainty about the potential impacts of the COVID-19 pandemic on our business. For this reason, as part of its approval process in March 2020, the Committee acknowledged the potential need to exercise discretion in determining bonus funding, as permitted under the 2020 Annual Bonus Plan, to account for the possible and unknown severity of the pandemic's impact on our business in 2020.

The COVID-19 pandemic did have a significant impact on our business in 2020. The significant deferral of and lowered demand for elective procedures, combined with COVID-related disruption to our operations, resulted in a substantial decrease in revenues and adjusted earnings per share. As a result, both our net sales and EPS performance were below threshold levels under the Plan, which would have yielded a 50% funding factor for the Total Bonus Pool Funding.

After approving the possible use of discretion in determining the funding level for the 2020 Annual Bonus Plan, the Committee regularly discussed and assessed, with input from Semler Brossy, its compensation consultant, COVID-19's impact on the business and on the possible bonus plan funding for 2020.

In the second quarter, the effects of COVID-19 began to materially impact our results. The uncertainty and instability caused by COVID-19 made it extremely difficult to predict, throughout 2020, what the total impact of the pandemic would be on our business in 2020. Given this ongoing uncertainty, the Committee determined that it was not appropriate to revise our 2020 Company-level financial performance metric targets. Instead, the Committee, with support from Semler Brossy, developed a scorecard that would help assess management's performance in addressing the business disruption COVID-19 caused in 2020. The scorecard included the following categories of key performance indicators: Financial Performance, Strategic Initiatives, COVID Response, Actions Towards Future Success, and Employee Actions.

Holistic Evaluation of Performance and Achievement and Exercise of Positive Discretion

After undertaking a holistic evaluation of Company performance in light of the critical actions and strategic achievements listed in the table below, the Committee used positive discretion to adjust the 2020 Annual Bonus Plan funding from 50%, the level that would've been indicated based on the plan approved prior to COVID-19, to 77%, as described more fully below.

Key among the Committee's considerations was Company performance against the approved financial plan, which would have resulted in funding the 2020 Annual Bonus at the 50% funding floor. The Committee also reviewed Company performance against two alternative financial models, both presented in early April, which were based on early estimates of the potential impact of COVID-19 on our business. The first alternative financial model would have resulted in a bonus funding between 70% and 82.5% and the second would have suggested a bonus funding at over 100%.

The Committee's decision to exercise positive discretion in approving the 2020 Total Bonus Pool reflects the Committee's collective judgment in balancing the final, actual results against the approved plan with where the results could have ended in an extremely challenging business environment, had it not been for the critical role employees and the executive team played in navigating the Company through the performance year and preparing the Company for 2021 and beyond. The Committee reviewed Company performance against the original bonus plan targets, the revised financial models, our original Quality Goals and Objectives, and the key strategic accomplishments listed above, and considered the Company's strong response to the COVID-19 pandemic. After doing so, in accordance with the terms of the plan, our Chief Executive Officer recommended, and our Compensation Committee approved a Total Annual Bonus Pool Funding of 77%, for approximately 15,000 eligible employees including our NEOs.

In prior years, the Total Bonus Pool, as funded, is allocated by the Compensation Committee to each participating regional, business, and functional unit taking into consideration our Chief Executive Officer's recommendations in light of that participating unit's performance measured against its operational and/or financial performance metric targets (and other factors the Compensation Committee deems appropriate), thereby incentivizing and rewarding each participating unit's performance contributions. However, in order to balance the uneven impact of the COVID-19 pandemic on our global businesses, regions, and functions, the Compensation Committee, upon the

recommendation of our CEO, determined that all participating units would have a Participating Unit Performance Percentage of 75% under the 2020 Annual Bonus Plan.

Each executive's target award opportunity under the Annual Bonus Plan is expressed as a percentage of his or her annual base salary and is determined based on the scope of the executive's responsibilities. For 2020, our Compensation Committee maintained the target award opportunities for our 2019 NEOs in 2020. The following table shows target award opportunities in 2020 for our NEOs, and, for those NEOs who were also NEOs for 2019, their target opportunities in 2019. The target award opportunities for Messrs. Brennan, Fitzgerald, Mackey, and Mirviss were based on the recommendations of our CEO, internal pay equity relative to our other executives, their impact and experience in their roles and external market data.

After year end, individual performance is considered pursuant to the PDC process described in the "Performance Considerations" section above. Based on the performance assessment rating under our annual PDC process, an individual performance multiplier from 0% to 150% is applied to an executive's funded Annual Bonus Plan award to determine the actual amount to be paid. Final payout for each executive may therefore range from 0% to 225% of target, as the product of the funded award under Participating Unit performance percentage, ranging from 50% to 150% of target, and the individual performance multiplier, ranging from 0% to 150%.

Our NEOs had certain performance objectives intended to support our strategic imperatives, as applicable to their roles, including (i) with respect to our NEOs who support corporate functions, those aimed at driving Company-level financial performance objectives, and (ii) with respect to Messrs. Fitzgerald and Mirviss who each supports a business or businesses, those aimed at supporting business-level financial and operational performance objectives. The individual performance objectives discussed below represent factors that are considered by the Compensation Committee and our CEO in determining each NEO's individual performance percentage. Further, no single factor is determinative or required to be considered.

Short-term Incentive Awards Paid to Our NEOs Under Our 2020 Annual Bonus Plan

Our Compensation Committee annually reviews the design of our Long-Term Incentive Program (LTI Program) to help ensure that the program continues to support our executive compensation philosophy and core compensation program objectives. In setting the design for 2020, our Compensation Committee retained the mix of equity award opportunities for our executives under our prior LTI Program that were designed to further reinforce "pay for performance" and align the interests of our executives and their compensation with important Company financial measures and the long-term interests of our stockholders. The key features and objectives of each equity vehicle are summarized in the table below.



		Performance-Based DSUs (50% of total mix) 50% Relative TSR; 50% Adjusted Free Cash Flow

		Performance-based DSUs are intended to complement the performance orientation of our other equity vehicles — which are linked to the appreciation of our share price — and further align the interests of our shareholders and executives. This linkage is achieved by tying vesting opportunities to the attainment of goals that are leading indicators of our financial health and ability to create substantial value for our shareholders. At this time, the Compensation Committee believes that adjusted free cash flow and relative TSR are the best measures of long-term success, as they promote strong capital discipline, prioritize sustainable value creation, and align the interests of our executives and shareholders.

		*Relative TSR DSUs(1)(2)* Relative TSR performance-based DSUs align the interests of our executives and shareholders by measuring our total value creation against the S&P 500 Healthcare Index, which includes the majority of our peer companies, and encourages our executives to think like owners and make long-term oriented decisions. Performance is measured across three years, and shares vest between 0% and 200% of target based upon actual achievement. For 2020 TSR DSUs, the performance schedule was as follows: • Participants earn 40% of the relative TSR DSUs if our performance is at the 30^th percentile of the index (our payout threshold value). • All shares are forfeited for performance below the 30^th percentile, and a maximum of 200% of shares are earned for achievement at or above the 80^th percentile. • Payouts are linearly interpolated between points on the payout grid. • Awards typically vest upon satisfaction of both performance and service criteria at the end of the three-year performance period.



		*Free Cash Flow DSUs(1)(2)(3)* FCF performance-based DSUs, in conjunction with the measures in our annual incentive plan, align executive compensation opportunities with achievement of a key objective in the Company's internal financial plan and an important area of focus for stockholders. The performance period of one year maximizes our nimbleness in a highly variable operating environment, while the three-year service criteria (inclusive of the performance period) promotes a long-term orientation and retention. In 2020, our Adjusted Free Cash Flow target goal was $2.100 billion, which aligned with the Board-approved 2020 internal cash flow plan. • Participants earn 25% of the FCF DSUs if our performance is at 50% of plan. • All shares are forfeited for performance below 50% of plan, and a maximum of 150% of shares are earned for achievement at or above 125% of plan. • Payouts are linearly interpolated on the payout grid. • Any shares earned vest in full three years following the grant date.

		*Service-Vesting Equity Vehicles (50% of total mix)(1)(2)*** 50% Service-Based DSUs; 50% Non-Qualified Stock Options

		*Service-Based DSUs*
		Service-based DSUs reinforce pay for performance by linking the ultimate value of the award to performance of our stock. The vesting period acts as a retention tool and promotes executive long-term share owner perspective.

		• For awards granted in 2020, DSUs vest in four equal annual installments subject to continued service
		• Service-based DSUs granted under programs prior to 2019 vested in five equal annual installments
		• Promote executive ownership and linkage to our share price

		*Non-Qualified Stock Options(1)*
		Non-qualified stock options represent the right to purchase our common stock at an exercise price equal to the closing price of our common stock on the date of grant. As such, executives only receive value to the extent that our share price increases through the exercise period.

		• Vest in four equal annual installments subject to continued service
		• Provide value only to the extent that our share price increases
		• Are exercisable from the vesting date through the tenth anniversary of the grant date

For further discussion of the performance share programs for our Company performance-based DSUs and the equity awards granted pursuant to our Long-Term Incentive Plans (LTIPs) and a description of how we calculate adjusted free cash flow, please see the Executive Compensation sections titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Total Shareholder Return Performance Share Program," "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Free Cash Flow Performance Share Program" and "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — Amended and Restated 2011 Long-Term Incentive Plan" and Annex A.

In February 2020, our Compensation Committee approved the grant of long-term equity incentive awards to our NEOs in the amounts in the following table, which were based on the target dollar values of the long-term equity incentive awards for our NEOs considered by the Compensation Committee (see discussion of the target dollar values below). In approving the following grants, the Committee considered external market data and internal factors, including internal equity, performance, and potential. In evaluating internal equity between the CEO and non-NEOs, the Committee focused, in particular, on competitive market data, and the Company's organizational structure.

The numbers of FCF and TSR performance-based DSUs and service-based DSUs were calculated by dividing the target dollar value of those awards by the closing price of our common stock on the date

of grant, and the numbers of stock options were determined by dividing the target dollar value of that award by the stock option value determined in accordance with FASB ASC Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table".

We also made equity grants to two of our NEOs outside of the ordinary annual award process. In February 2020, Mr. Mackey was awarded 23,719 DSUs for retention purposes, which vest in a single installment on February 18, 2022, the second anniversary of the grant. Additionally, in July 2020, in connection with Mr. Fitzgerald's appointment to the position of Executive Vice President and President, Interventional Cardiology, Mr. Fitzgerald was granted an equity incentive award in the form of 116,959 non-qualified stock options, which have an exercise price of $35.28 per share and vest in one single installment on January 1, 2023. The grant date fair value of each of these equity grants was approximately $1,000,000.

Company Performance-Based DSUs — Results for Performance Periods Ended December 31, 2020

In February 2021, our Compensation Committee determined the number of deferred stock units earned pursuant to our performance-based DSUs under the 2018 TSR Performance Share Program and the 2020 FCF Performance Share Program, presented in the table below.

We also compensate our executives, including our NEOs, with indirect compensation, namely in the form of benefits and limited perquisites. Generally, our benefits and perquisites are targeted to be competitive relative to our peer group companies. The primary elements of and objectives for our NEOs' 2020 indirect compensation are summarized below.

We provide employee benefits to eligible employees, including our NEOs, to promote personal health and well-being and to provide certain financial security and protection upon retirement or in the event of death, disability or illness. As U.S.-based employees, our NEOs are eligible to receive employee

benefits under our U.S. employee benefits program, which consists of the following key elements that are generally the same as those provided to our other U.S. salaried employees:

In addition, our executive officers may participate in an annual executive level physical examination program that is designed to encourage the proactive management of executive health. In approving the program, the Compensation Committee considered the overall cost of the program (estimated to be less than $10,000 per participant) and the importance of good health to an executive's ability to focus on the short and long-term needs of the Company. Company-paid term life insurance premium amounts (and related imputed income), Company matches of 401(k) Plan contributions for our NEOs, Company-paid executive level annual physical examination costs, and certain other reimbursements in 2020 are reported in the footnotes to the Executive Compensation section titled "Summary Compensation Table."

We maintain a Deferred Bonus Plan for certain of our management, including our NEOs, in order to provide them with the opportunity to defer up to 75% of their annual award under our Annual Bonus Plan until the earlier of termination of employment or an elected distribution date. However, in April 2020, the Compensation Committee determined that no deferral elections would be permitted under the Deferred Bonus Plan for the 2020 Annual Bonus, if any, payable in 2021. For additional discussion of the Deferred Bonus Plan, please see the narrative to the Executive Compensation section titled "Nonqualified Deferred Compensation."

We provide tiered relocation benefits under our relocation program to eligible employees, including our NEOs, whom we request to move in connection with their current position or a promotion and for eligible new hires we require to move in connection with accepting a position with us. Our objectives in providing relocation benefits are to attract and redeploy top talent. We provide "tax gross-ups" on applicable relocation benefits provided under our relocation program as we believe that this benefit is integral to the Company's ability to attract and retain employees whose skill or knowledge enhance the Company's competitive position. Participants are generally required to sign a reimbursement agreement that requires them to pay back expenses incurred by the Company for their relocation in the event that they voluntarily terminate their employment or are terminated for "cause" at a rate of 100% for termination within one year of the date on which payments were first made and 50% for termination following the first year but within two years of the date on which payments were first made.

Pursuant to Mr. Mahoney's offer letter, he is permitted reasonable personal use of our corporate aircraft up to $100,000 per year in aggregate incremental cost to the Company. Our other executives are permitted limited personal use of our corporate aircraft with prior approval. These executives are personally taxed on their personal use of our corporate aircraft and we do not provide them with income tax gross-up payments. The aggregate incremental cost to the Company (and disallowed tax deductions of the Company) for our NEOs' personal use of our corporate aircraft in 2020 is included in the footnotes to the Executive Compensation section titled "Summary Compensation Table."

We offer a financial planning perquisite for our executive officers, including our NEOs. The program provides financial counseling and planning, investment and retirement management, insurance planning, and income tax planning and preparation services through a single service provider for US-based executive officers. Executive officers located outside of the United States will be eligible for reimbursement. In approving the program, the Compensation Committee considered the overall cost of the benefit (up to $12,000 per participant), prevalence of the benefit in the market, and benefit to the Company of reducing potential distraction to executive officers of complex personal financial situations.

None of our NEOs has an employment agreement with the Company. However, we provide post-employment and change in control payments and benefits to our executives under certain circumstances. We believe that offering our executives these payments and benefits facilitates the operation of our business, allows them to better focus their time, attention and capabilities on our business, and assists the Company in recruiting and retaining key executives. The primary elements of and objectives for our NEOs' 2020 post-employment and change in control agreements are summarized below.

Our executives are eligible to participate in our defined benefit Executive Retirement Plan. For further discussion of our defined benefit Executive Retirement Plan, please see the narrative to the Executive Compensation section titled "Defined Benefit Retirement Plan."

We maintain severance plans for eligible employees, including our NEOs, under which participants are entitled to receive certain severance payments, subsidized COBRA health benefits and dental benefits for specified periods of time. For further discussion of our severance plans, please see the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control — Severance Plans."

We have entered into change in control agreements to our executives, including our NEOs, and other key employees (Change in Control Agreements). The possibility of a change in control and the

uncertainty that it may raise among our executives as to their continued employment after or in connection with a change in control may result in their departure or distraction. Our objective in providing Change in Control Agreements is to retain and encourage the continued attention and dedication of our executives during a potentially critical time, even if they are concerned that their position will be eliminated after or in connection with the change in control. Our Change in Control Agreements require both a change in control and termination without cause or resignation for good reason within two years after the change in control event, commonly referred to as a "double-trigger," for cash payments to be made under the agreement and vesting to be accelerated under the agreements for equity awards where the surviving or acquiring entity substitutes or assumes outstanding equity awards.

For further discussion of our Change in Control Agreements, other plans and arrangements under which a change in control and/or termination of employment triggers payments or benefits, and potential payments to our NEOs under the foregoing, please see the narrative and tables in the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control — Change in Control Agreements."

Our Compensation Committee has adopted a policy regarding the recovery or adjustment of short-term incentive awards paid to an executive in the event relevant Company performance measures are restated in a manner that would have reduced the size of a previously granted award. In such an event, and to the extent permitted by applicable law, the Company would seek to recover the amount of the short-term incentive award paid to such executive that was in excess of the amount that would have been awarded based on the restated financial results, subject to and in accordance with the terms of the policy. Our Compensation Committee monitors regulatory developments with respect to applicable executive compensation recovery policies required by the Dodd-Frank Wall Street Reform and Consumer Protection Act and it expects to consider such changes to the Company's current recovery policy as are necessary to comply with final rules (and related guidance, if any) to be issued by the SEC in accordance with such act.

Our Compensation Committee has also adopted a policy regarding the recovery of certain short- and long-term incentive compensation awards paid or granted to an executive in the event of executive misconduct or gross dereliction of duty that resulted in a material violation of Company policy and caused significant harm to the Company. In such an event, and to the extent permitted by applicable law, the Company may seek reimbursement of all or a portion of cash incentive compensation awards paid within a certain time period and/or recovery of all or a portion of equity incentive awards granted to such executive over which the Company retains control, subject to and in accordance with the terms of the policy.

Both of the policies described above are only applicable to awards made after the adoption of the relevant policy. For a discussion of other recovery and forfeiture provisions relating to incentive compensation awards and other benefits provided to our executives, please see the section titled "Relocation Program" above, and the Executive Compensation sections titled "Retirement Plan Benefits" and "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table."

Our executives are required to have a significant personal investment in the Company through their ownership of shares of our common stock. Our Board has set stock ownership guidelines for

executives, including our NEOs, as a number of shares of Company stock equal in value to at least the following amounts:

Executives are required to comply with the guidelines at all times. However, if at any time an executive's ownership does not meet or exceed the guideline, he or she is expected to retain ownership of at least fifty percent of net shares with respect to each vesting of an equity award or stock option exercise until the guideline is met or exceeded. For purposes of satisfying the guidelines, shares owned outright, shares held in company benefit plans and the intrinsic value of vested "in-the-money" stock options are included in the aggregate number of shares held by an executive. Unvested equity award shares (including service-based DSUs and performance-based DSUs) and unvested stock options are not included in the aggregate number of shares held by an executive. The Nominating and Governance Committee monitors compliance with these guidelines on an annual basis. As of December 31, 2020, our CEO and other NEOs were in compliance with these guidelines.

The Company does not provide tax gross-ups for our executives, except for relocation benefits because the benefit generally applies to all employees eligible to receive relocation benefits, including our executives, and the Compensation Committee believes it is integral to the Company's ability to attract and redeploy employees whose skill or knowledge enhance the Company's competitive position.

Under our Equity Award Grant Policy, grants of equity awards to our executives are approved and effective as follows:

Section 162(m) of the Code (Section 162(m)), as amended by the Tax Cuts and Jobs Act, generally disallows a tax deduction to public companies for compensation over $1 million paid to certain "covered employees," which includes a company's CEO, CFO, and the three other most highly compensated executive officers employed by the company at the end of the year. Once an officer is a

"covered employee," their compensation will remain subject to Section 162(m) for so long as they are receiving compensation from the company. Further, the Tax Cuts and Jobs Act repealed the exclusion for "qualified performance-based compensation" under Section 162(m) effective January 1, 2018, except for compensation payable pursuant to a written binding contract in place before November 2, 2017 that is not materially modified thereafter (a grandfathered arrangement). The company may avail itself of this transition rule for grandfathered arrangements, to the extent applicable and that our existing plans and outstanding awards qualify. To maintain flexibility in compensating executive officers in a manner designed to promote varying corporate goals in the best interest of the Company, the Committee does not limit its actions with respect to executive compensation to preserve deductibility under Section 162(m) if the Committee determines that doing so is in the best interests of the Company.

The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, which requires the Company to recognize compensation expense for share-based payments (including stock options and other forms of equity compensation). FASB ASC Topic 718 is taken into account by the Compensation Committee in determining to use a portfolio approach to equity grants, awarding both stock options and DSUs.

Our executives, including our NEOs, and our directors, are prohibited from speculating in the Company's securities, engaging in transactions designed to "hedge" the value of our common stock, and pledging their common stock as collateral for a loan. Examples of hedging and pledging transactions specifically covered by the policy include zero-cost collars and forward sale contracts, and use of stock as margin to secure borrowings, respectively. To facilitate the implementation of this prohibition, excluded from the policy's general prohibition on hedging and pledging arrangements are shares held by directors that were subject to hedging or pledging arrangements as of December 31, 2010, and do not in the aggregate for all directors amount to more than 3.5% of the Company's then outstanding shares. None of our executives or directors is engaged in hedging or pledging arrangements related to the Company's securities.

With the assistance of the senior members of our Global Compensation and Benefits organization, certain senior executive officers and the Compensation Committee's independent compensation consultant, Semler Brossy, in February 2021 the Compensation Committee reviewed a risk assessment of our compensation programs and policies to determine if the provisions and operations of our programs create undesired or unintentional risk of a material nature.

Our risk assessment included two work streams — one focused on reviewing areas of enterprise risk and the other focused on identifying compensation design risk. Our enterprise risk analysis examined the types and magnitudes of risks our business areas present to the Company so that the Committee could assess the extent to which our compensation programs may mitigate or exacerbate these risks. Our compensation design risk analysis, which was conducted by management and reviewed by Semler Brossy, examined the potential risks in the design of our performance-based incentive compensation arrangements. As part of this assessment, we analyzed the mix of fixed and variable compensation; the mix of short- and long-term compensation; the mix of long-term equity incentives; performance metric mix; weighting, measurement and payout timing; discretion and caps on short-term incentives; award size, vesting schedules and performance and other terms of long-term equity incentives; and other incentive opportunities and their features. We also analyzed our recovery of incentive awards policy, executive stock ownership guidelines and hedging and pledging prohibitions. Finally, we evaluated on a combined basis the results of the enterprise and compensation risk assessments, on a business area-by-business area basis.

The Compensation Committee reviewed and discussed the findings of this analysis with management and concluded that it continues to believe that our compensation programs do not create risks that are reasonably likely to have a material adverse effect on the Company.

The Compensation Committee has reviewed and discussed the Compensation Discussion & Analysis contained in this Proxy Statement with management and, based on such review and discussions, the Compensation Committee has approved the inclusion of the Compensation Discussion & Analysis in this Proxy Statement and in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 for filing with the SEC.

This Compensation Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Boston Scientific filing with the SEC, except to the extent that Boston Scientific specifically incorporates this Report by reference into another Boston Scientific filing.

The table below summarizes the total compensation for each of our named executive officers for the years ended December 31, 2020, 2019 and 2018.

(1)		Base salaries for our executive officers are generally effective for one year starting in late February of each year. The amounts in this column for 2018 and 2019 reflect an amount calculated by prorating the prior year's base salary until late February, and then 2018 and 2019 base salaries, respectively, for the remainder of the year. In April 2020, the Company announced that, in light of the disruption and uncertainty created by the evolving COVID-19 pandemic and its anticipated impact on the Company's operations, all of our Executive Officers, including our NEOs, would take a significant temporary reduction in base salary for up to six months. For our NEOs other than Mr. Mahoney, the temporary salary reductions were terminated in August 2020, and for Mr. Mahoney, the reduction ended in October 2020. Therefore, for each NEO, the amounts in this column for 2020 reflect an amount calculated by prorating the individual's 2019 salary from January 1, 2020 through February 16, 2020; then prorating the regular 2020 base salary and temporarily reduced base salary amounts for the applicable periods throughout the year.
		For each year, these figures differ from those in the Compensation Discussion & Analysis, which lists amounts approved by the Compensation Committee for 2020.
(2)		The amounts included in the "Stock Awards" column represent the aggregate grant date fair value of all service-based and Company performance-based DSUs granted in 2020, 2019 and 2018 under our 2011 LTIP, as effective on the respective dates of grant. These values have been determined in accordance with FASB ASC Topic 718.
		The attainment of the performance-based DSUs awarded to our NEOs in 2020 is based on either (i) the Total Shareholder Return (TSR) of our common stock relative to the TSR of the common stock of the other companies in the S&P 500 Healthcare Index over a three-year performance and service period, or (ii) our adjusted free cash flow over a one-year performance period measured against our 2020 internal financial plan for the same period, subject to the satisfaction of the service criteria over a three-year period (inclusive of the performance period). For additional information with respect to these Company performance-based DSUs, including the vesting thereof, please see the sections titled "2020 Total Shareholder Return Performance Share Program" and "2020 Free Cash Flow Performance Share Program" in the narrative to this table.


		The TSR performance metric for the 2020 TSR performance-based DSUs is a market condition as defined under FASB ASC Topic 718. Because these awards do not have performance conditions as defined under FASB ASC Topic 718, such awards have no maximum grant date fair values that differ from the fair values presented in this Summary Compensation Table.
		The grant date fair value of the 2020 FCF performance-based DSUs was determined based on management's evaluation of the Company's 2020 internal financial plan for adjusted free cash flow, assuming target achievement of the adjusted free cash flow performance criteria and utilizing the closing price of our common stock on the date of grant. The fair values of the 2020 target FCF performance-based DSUs at the grant date assuming achievement of the highest level of performance (as required to be disclosed by the SEC), which assumes actual adjusted free cash flow for 2020 at or above 125% of the Company's 2020 internal financial plan, are as follows: $4,124,955 for Mr. Mahoney's award, $937,470 for Mr. Brennan's award, $937,470 for Mr. Fitzgerald's award, $562,457 for Mr. Mackey's award, and $712,462 for Mr. Mirviss.
		We value service-based DSUs based on the closing price of shares of our common stock on the date of grant.
		For more information regarding the stock awards we granted in 2020, please see the Grants of Plan-Based Awards table. For a more detailed description of the assumptions used in determining grant date fair values of DSUs granted in 2020, please see Note L — Stock Ownership Plans to our 2020 consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020.
(3)		The amounts included in the "Option Awards" column represent the aggregate grant date fair value of all stock options granted during each of 2020, 2019 and 2018 under our 2011 LTIP, as effective on the respective date of grant. These values have been determined in accordance with FASB ASC Topic 718. For a description of the assumptions used for purposes of determining grant date fair value of stock options granted in 2020, please see Note L — Stock Ownership Plans to our 2020 consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020. For more information regarding the stock option awards we granted in 2020, please see the Grants of Plan-Based Awards table.
(4)		Amounts in the "Non-Equity Incentive Plan Compensation" column represent cash awards made under our Annual Bonus Plan to our NEOs paid in February of the following year. Such amounts may be deferred under the Deferred Bonus Plan.
		For further information regarding the 2020 Annual Bonus Plan awards, please see the Compensation Discussion & Analysis section titled "Short-Term Incentives," the narrative to this table, and "Nonqualified Deferred Compensation".
(5)		The amounts shown in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column reflect the change in the actuarial present value of the accumulated benefit under our Executive Retirement Plan for each retirement plan measurement date used for financial statement reporting purposes with respect to the Company's audited financial statements as compared to the prior retirement plan measurement date.
		Please see the narrative and related footnotes to the table in the section titled "Defined Benefit Retirement Plan" for more information regarding the accrued benefits for each NEO under this plan. No amount is included with respect to nonqualified deferred compensation earnings because there were no above-market or preferential earnings on nonqualified deferred compensation.


(a)		The amounts shown in this column represent matching contributions made by the Company for each NEO under our 401(k) Retirement Savings Plan. All individual and matching contributions to the 401(k) Retirement Savings Plan are fully vested upon contribution.
(b)		Pursuant to Mr. Mahoney's offer letter, he is permitted reasonable personal use of our corporate aircraft up to $100,000 per year in aggregate incremental cost to us, but he is not entitled to reimbursement by us for any taxes resulting from imputed income attributable to his personal use of the corporate aircraft. In light of the fact that Mr. Mahoney's travel plans are subject to change on short notice, the Company has agreed that he may use our corporate aircraft in connection with his service on the board of directors of Baxter International, Inc. so long as he fully reimburses us for the incremental costs associated with such travel or such costs are counted against his annual personal use amount.
		The amount reflected in the "Aircraft" column represents the aggregate incremental costs to us for personal use by the NEO of our corporate aircraft, as well as any incremental costs associated with persons accompanying such officer on business travel. We calculate the incremental cost to us by dividing the total annual variable operating costs for the corporate aircraft by the number of in-flight hours during the year. The resulting dollar per hour amount is then multiplied by the number of hours flown for personal use by the executive officer during the year, including the "dead head" costs of flying the aircraft to and from locations for personal use. Our corporate aircrafts are used predominantly for business travel. We do not include the fixed operating costs, such as pilot salary, general taxes and insurance, in the incremental cost calculation. The incremental cost does not include amounts attributable to the NEO for increased income taxes we incurred in 2020 as a result of disallowed deductions related to personal use under Internal Revenue Service rules. For 2020, the reflected amounts exclude $218,784 and $15,045 of disallowed corporate income tax deductions attributable to the personal use of the corporate aircraft during the year by Messrs. Mahoney and Brennan, respectively. Messrs. Mahoney and Brennan were taxed on the imputed income attributable to their respective personal use of the corporate aircraft and did not receive tax assistance from the Company with respect to this amount.
(c)		Amounts in the "Term Life Insurance" column consist of premiums and the imputed income for Company-paid term life insurance attributable to our NEOs. For Messrs. Mahoney, Brennan, Fitzgerald, Mackey, and Mirviss, the premium paid was $792, $537, $545, $477, and $455 respectively.
(d)		Amounts in the "Financial Planning" column reflect fees paid to a service provider for financial planning. In November 2019, our Compensation Committee approved a financial planning perquisite for our executive officers, including our NEOs. The program provides financial counseling and planning, investment and retirement management, insurance planning, and income tax planning and preparation services through a single service provider for US-based executive officers. Executive officers located outside of the United States will be eligible for reimbursement. In approving the program, the Compensation Committee considered the overall cost of the benefit (up to $12,000 per participant), prevalence of the benefit in the market, and benefit to the Company of reducing potential distraction to executive officers of complex personal financial situations.
(e)		Amounts in the "Other" column consist of the costs of miscellaneous gifts/prizes and annual physical examinations, where applicable.

The table below presents information regarding awards under the Company's 2020 Annual Bonus Plan and 2011 LTIP, including those pursuant to the Company's 2020 Performance Share Programs, during the year ended December 31, 2020.

(1)		The amounts in these columns reflect target and maximum payouts under the 2020 Annual Bonus Plan. There is no threshold-level payout under the 2020 Annual Bonus Plan. The maximum possible payout under the 2020 Annual Bonus Plan is 225% of the target payout, representing the product of (i) a maximum of 150% of the target payout based on Company performance metrics and (ii) a maximum of 150% of the target payout based on individual performance objectives. The actual amount earned by each NEO under the 2020 Annual Bonus Plan is reported under the "Non-Equity Incentive Plan Compensation" column in the Summary Compensation Table. For additional information about our 2020 Annual Bonus Plan and a discussion of how these amounts are determined, please see the Compensation Discussion & Analysis section titled "Short-Term Incentives" and the section titled "2020 Annual Bonus Plan" in the narrative to this table.

The target performance-based DSUs awarded under these programs were granted to our NEOs in February 2020 as part of our annual review process and were awarded under our 2011 LTIP, as effective on the date of grant. For additional details regarding the awards to our NEOs pursuant to our 2020 TSR PSP and 2020 FCF PSP, please see footnotes 5 and 6 to this Grants of Plan-Based Awards table, respectively.
(3)		The Compensation Committee took action to grant the awards in this table on February 12, 2020, and determined that the awards should be granted as of February 18, 2020.
(4)		The amounts in these columns reflect the number of service-based DSUs and stock options granted to our NEOs under our 2011 LTIP as effective on the date of grant during 2020.


(5)		The amounts in this column have been determined in accordance with FASB ASC Topic 718. See footnotes 2 and 3 to the Summary Compensation Table for a description of the assumptions used in determining the grant date fair value of these awards.
(6)		These awards were granted pursuant to our 2020 TSR PSP. The threshold award level represents the minimum share issuance for each award that a participant may receive based on performance, which is 40% of the target TSR performance-based DSUs awarded under the program. The maximum share issuance for each award is 200% of the target TSR performance-based DSUs awarded under the 2020 TSR PSP. For additional information about our 2020 TSR PSP and a discussion of how these amounts are determined, please see the section titled "2020 Total Shareholder Return Performance Share Program" in the narrative to this table.
(7)		These awards were granted pursuant to our 2020 FCF PSP. The threshold award level represents the minimum share issuance for each award that a participant may receive based on performance, which is 25% of the target FCF performance-based DSUs awarded under the program. The maximum share issuance for each award is 150% of the target FCF performance-based DSUs awarded under the 2020 FCF PSP. For additional information about our 2020 FCF PSP and a discussion of how these amounts are determined, please see the section titled "2020 Free Cash Flow Performance Share Program" in the narrative to this table.

The following provides information about the terms of our 2020 Annual Bonus Plan, 2020 Performance Share Programs and our 2011 LTIP, pursuant to which our NEOs were awarded short- and long-term incentive compensation, as applicable and detailed in the tables above. For additional information regarding the application of these plans and programs to our NEOs in 2020, please see the Compensation Discussion & Analysis.

Our 2020 Annual Bonus Plan is administered by our Compensation Committee. The plan year for our 2020 Annual Bonus Plan ran from January 1, 2020 to December 31, 2020. Generally, all U.S. salaried employees not eligible for commissions under sales compensation plans and certain international employees selected for participation were eligible to participate in our 2020 Annual Bonus Plan, provided they had at least two full months of service during the plan year. Participants generally must be employed with us on the date payments are made in order to receive awards under the plan. However, in the event of death or retirement or certain involuntary terminations without cause, in each case, as described in the 2020 Annual Bonus Plan, participants may receive their performance incentive awards for the year on a prorated basis based on the percentage of the year the participant was employed by us and eligible to participate. Participants who have at least two months of eligibility, but less than a full year, similarly may receive awards under the 2020 Annual Bonus Plan on a prorated basis.

Each participant is provided with a target incentive award opportunity under the 2020 Annual Bonus Plan expressed as a percentage of his or her base salary. For a discussion of the 2020 target incentive award opportunities for our NEOs, please see the Compensation Discussion & Analysis sections titled "Individual Target Incentive Award Opportunity" and "2020 Annual Bonus Plan Awards Paid to Our NEOs."

Company Performance Metrics and Weighting. Under the 2020 Annual Bonus Plan, after year-end, a single Company-wide annual bonus pool (Total Bonus Pool) is funded based on the Company's performance measured against important Company-level financial performance metric targets. For 2020, our Compensation Committee selected adjusted EPS and adjusted net sales as our Company-level performance metrics. Each metric has a 50% weighting.

Company Metrics Defined. For purposes of our 2020 Annual Bonus Plan: (i) adjusted EPS equals adjusted net income (loss) divided by weighted average shares outstanding for the performance year (adjusted net income (loss) equals GAAP net income (loss) excluding certain charges (credits) from GAAP net income, including, but not limited to, amortization expense, goodwill and intangible asset impairment charges, acquisition- and divestiture-related net charges (credits), restructuring and restructuring-related net charges (credits), litigation-related net charges (credits), certain investment impairment losses (gains), EU Medical Device Regulation implementation charges, pension termination charges, and discrete tax items); and (ii) adjusted net sales is calculated at an assumed standard constant currency basis that excludes the impact of foreign currency fluctuations, which are highly variable and difficult to predict, and other adjustments.

For a discussion of the Company level targets under the 2020 Annual Bonus Plan, funding of the Total Bonus Pool and the individual performance component of the 2020 Annual Bonus Plan, and the impact of COVID-19 on the program, please see the Compensation Discussion & Analysis section titled "Short-Term Incentives."

Our 2020 Annual Bonus Plan provides that, to the extent permitted by applicable law, our Board will seek reimbursement of incentive compensation paid to any executive officer under the plan in the event of a restatement of our financial results that reduced a previously granted award's size or payment. Under such circumstances, and to the extent permitted by applicable law, we would seek to recover the amount of the 2020 Annual Bonus Plan award paid to such executive that was in excess of the amount that would have been paid based on the restated financial results. Additionally, our 2020 Annual Bonus Plan provides that to the extent permitted by applicable law, our Board may seek reimbursement of incentive compensation paid to an executive under the plan in the event of executive misconduct or gross dereliction of duty that resulted in a material violation of Company policy and caused significant harm to the Company. In such an event, and to the extent permitted by applicable law, the Board may seek reimbursement of all or a portion of cash incentive compensation awards paid within a certain time period under the plan.

Our 2020 TSR PSP is administered under our 2011 LTIP, as effective at the time of grant of performance-based DSUs under the program. The TSR performance-based DSUs awarded under the TSR PSP vest upon the satisfaction of both the Company performance criteria and service criteria under the 2020 TSR PSP, subject to acceleration in the event of certain qualifying terminations discussed below. Our executives, including our NEOs, are eligible to participate in the 2020 TSR PSP, which is administered by our Compensation Committee. For a discussion of the TSR performance-based DSUs awarded to our NEOs in 2020, please see the Compensation Discussion & Analysis section titled "2020 Long-Term Incentive Awards for our NEOs."

For a discussion of the Company performance criteria under the 2020 TSR PSP, please see the Compensation Discussion & Analysis section titled "2020 Long-Term Incentive Awards for our NEOs."

Calculation of TSR and Percentile Performance. The TSR for the Company and each other company in the S&P 500 Healthcare Index for the three-year performance period is determined based on the following formula:

The change in stock price is determined by subtracting the beginning stock price (the daily average closing price of one share of common stock for the two calendar months prior to the beginning of the performance period) from the ending stock price (the daily average closing price of one share of common stock for the last two calendar months of the performance period). The dividends paid are the total of all cash dividends paid on one share of common stock during the performance period.

Following the calculation of the TSR for the three-year performance period for our Company and each of the other companies in the S&P 500 Healthcare Index, the companies will be ranked in order of maximum to minimum TSRs for the full three-year performance period. Our percentile performance will be determined by (i) dividing (a) our ranking versus that of the other companies in the S&P 500 Healthcare Index minus one, by (b) the total number of companies in the S&P 500 Healthcare Index minus one, and (ii) subtracting the result from one.

Generally under the 2020 TSR PSP, except with respect to termination of employment due to retirement, death or disability, or in connection with a change in control, in each case, as described in the 2020 TSR PSP and/or the 2011 LTIP, a participant must be employed with us on December 31, 2022 to be eligible to receive shares of our common stock in respect of his or her TSR performance-based DSUs as to which the performance criteria under the program have been satisfied.

For information regarding potential payments upon certain terminations of employment or in connection with a change in control, please see "Potential Payments Upon Termination or Change in Control."

Our 2020 FCF PSP is administered under our 2011 LTIP, as effective at the time of grant of performance-based DSUs under the program. The 2020 grants of FCF performance-based DSUs vest

upon the satisfaction of both the one-year Company performance criteria and the three-year service criteria (inclusive of the performance period) under the 2020 FCF PSP, subject to acceleration in the event of certain qualifying terminations discussed below. Our executives, including our NEOs, were eligible to participate under the 2020 FCF PSP, which is administered by our Compensation Committee. For a discussion of the 2020 FCF performance-based DSUs awarded to our NEOs and the Company's achievement of the Company performance criteria under the program, please see the Compensation Discussion & Analysis section titled "2020 Long-Term Incentive Awards for our NEOs."

For a discussion of the Company performance criteria under the 2020 FCF PSP, please see the Compensation Discussion & Analysis sections titled "Long-Term Incentives" and "2020 Long-Term Incentive Awards for our NEOs."

Generally under the 2020 FCF PSP, except with respect to termination of employment due to retirement, death or disability, or in connection with a change in control, in each case, as described in the 2020 FCF PSP and/or the 2011 LTIP, a participant must be employed with us on December 31, 2022 to be eligible to receive shares of our common stock in respect of his or her 2020 FCF performance-based DSUs as to which the performance criteria under the program have been satisfied.

Employees, directors and other individuals who provide services to us and our affiliates who, in the opinion of the Compensation Committee, are in a position to make a significant contribution to our success or that of our affiliates are eligible for Awards under our 2011 LTIP. An amendment and restatement of the 2011 LTIP was approved by our stockholders at the 2020 Annual Meeting of Stockholders and became effective on October 1, 2020. Among other things, the amendment and restatement extended the Company's ability to continue to grant awards beyond March 1, 2021, the expiration date of the 2011 LTIP as previously in effect, and to increase to the number of shares of our common stock available for issuance under the plan.

The purpose of the broad-based equity incentive award opportunities available for grant under our 2011 LTIP is to attract, retain, engage and focus key employees and other eligible participants on achieving long-term stockholder value by rewarding them for the increased performance of our common stock underlying such awards. Our 2011 LTIP is administered by our Compensation Committee and provides for the grant of restricted or unrestricted common stock, restricted stock units (for awards granted prior to October 2020, referred to as "deferred stock units"), options to acquire our common stock, and stock appreciation rights (SARs), including types of awards subject to attainment of performance conditions (collectively, Awards). Our 2011 LTIP prohibits repricing or replacement of options or SARs and the issuance of in-the-money options or SARs, and includes limitations on the amounts of grants and payments to any individual within a given year as well as certain other customary limitations.

Generally, the deferred stock units granted in 2018 to our executives, including our NEOs, vest in five equal annual installments or, beginning in 2019, four equal annual installments, in each case from the

first anniversary of the date of grant, subject to continued service on each applicable vesting date. Generally, stock options vest in four equal annual installments, subject to continued service on each applicable vesting date, and expire on the tenth anniversary of the date of grant.

Generally, except with respect to termination of employment due to retirement, death or disability, or in connection with a change in control, in each case, as described therein or as otherwise provided for in the applicable award agreement, all equity awards terminate to the extent not vested immediately prior to the cessation of employment, and to the extent vested but not exercised at such time, remain exercisable for the lesser of one year or until the expiration of the stated term of the award. Further, in the event of a termination for "cause" (defined as conviction of, or a failure to contest prosecution for, a felony, or misconduct or dishonesty that is harmful to our business or reputation), or as a result of reasons that cast such discredit on the individual as to justify immediate termination of the award, in each case, as determined in the Compensation Committee's sole discretion, all outstanding equity awards (including unexercised stock options, whether vested or unvested) terminate immediately upon notice of such termination.

For a discussion of our plans and arrangements under which a change in control and/or termination of employment triggers payments or benefits, including our 2011 LTIP, please see the narrative to the tables appearing in "Potential Payments Upon Termination or Change in Control." Potential payments to our NEOs in 2020 under such plans or arrangements are included in the tables appearing in "Potential Payments Upon Termination or Change in Control."

With respect to our executives, including our NEOs, our Compensation Committee set the mix of equity award opportunities under our 2020 Long-Term Incentive Program at 25% target TSR performance-based DSUs, 25% target FCF performance-based DSUs, 25% stock options and 25% service-based DSUs. The service-based deferred stock units granted in 2020 vest in four equal annual installments beginning on the first anniversary of the date of grant, subject to continued service on each applicable vesting date and except as set forth under "Certain Separations from Service." For a discussion of the 2020 equity awards made to our NEOs, please see the Compensation Discussion & Analysis section titled "Long-Term Incentives."

The following table provides information with respect to outstanding unexercised non-qualified stock options and unvested deferred stock units for each NEO as of December 31, 2020.

(1)		All stock options are non-qualified stock options and vest in four equal annual installments beginning on the first anniversary of the date of grant, subject to continued service on each applicable vesting date.
(2)		Unless otherwise noted, all service-based DSUs granted in 2017 and 2018 vest in five equal annual installments and beginning in 2019 all service-based DSUs will vest in four equal annual installments, in each case beginning on the first anniversary of the date of grant, subject to continued service on each applicable vesting date.
(3)		Unless otherwise noted, the amounts reflected in this column are based on the closing price of our common stock on December 31, 2020, which was $35.95.
(4)		In February 2018, each of our NEOs was awarded FCF performance-based DSUs under our 2018 FCF PSP. Our adjusted free cash flow performance over the one-year performance period that ended December 31, 2018 was 108.9% relative to target performance for the same period. Accordingly, in February 2019, the Compensation Committee determined that pursuant to the terms of the 2018 FCF PSP, 117.9% of the target number of FCF performance-based DSUs had satisfied the performance criteria under the program. These awards were settled in January 2021.
(5)		In February 2018, each of our NEOs was awarded TSR performance-based DSUs under our 2018 TSR PSP. Our total shareholder return performance was ranked 32nd relative to that of the other companies in the S&P 500 Healthcare Index over the performance cycle comprising the three-year period that ended December 31, 2020. Accordingly, in February 2021 the Compensation Committee determined that pursuant to the terms of the 2018 TSR PSP, 78% of the target number of TSR performance-based DSUs had been earned based on the performance criteria under the program. Amounts for these awards represent the number of shares of our common stock that were delivered or otherwise made available to our NEOs on February 10, 2021 in settlement of the units awarded to them in 2018.


(6)		In February 2019, each of our NEOs was awarded FCF performance-based DSUs under our 2019 FCF PSP. Our adjusted free cash flow performance over the one-year performance period that ended December 31, 2019 was 93.4% relative to target performance for the same period. Accordingly, in February 2020, the Compensation Committee determined that pursuant to the terms of the 2019 FCF PSP, 90.1% of the target number of FCF performance-based DSUs had satisfied the performance criteria under the program. Amounts for these awards represent the number of shares of our common stock that will be delivered or otherwise made available to our NEOs no later than January 15, 2022 in settlement of the units awarded to them in 2019 so long as the service criteria is also satisfied. As of December 31, 2020, such units were unearned and remained subject to forfeiture under the terms of the 2019 FCF PSP.
(7)		In February 2020, each of NEOs was awarded FCF performance-based DSUs under our 2020 FCF program. Our adjusted free cash flow performance over the one-year performance period that ended December 31, 2020 was 94.3% relative to target performance for the same period. Accordingly, in February 2021, the Compensation Committee determined that pursuant to the terms of the 2020 FCF PSP, 88.6% of the target number of FCF performance-based DSUs had satisfied the performance criteria under the program. Amounts for these awards represent the number of shares of our common stock that will be delivered or otherwise made available to our NEOs no later than January 15, 2023 in settlement of the units awarded to them in 2020 so long as the service criteria is also satisfied. As of December 31, 2020, such units were unearned and remained subject to forfeiture under the terms of the 2020 FCF PSP.
(8)		In February 2019, each of our NEOs was awarded TSR performance-based DSUs under our 2019 TSR PSP. In accordance with the SEC rules, the number of performance-based DSUs shown represents the number of units that may be earned as of December 31, 2020 based on threshold performance. The SEC rules require that the threshold number of units be disclosed because the number of units that would have been earned based on actual results under the performance conditions for the one-year period from January 1, 2020 through December 31, 2020 (instead of through the end of the performance period on December 31, 2021) did not exceed the threshold performance goal.
(9)		In February 2020, each of our NEOs was awarded TSR performance-based DSUs under our 2020 TSR PSP. In accordance with the SEC rules, the number of performance-based DSUs shown represents the number of units that may be earned as of December 31, 2020 based on threshold performance. The SEC rules require that the threshold number of units be disclosed because the number of units that would have been earned based on actual results under the performance conditions for the one-year period from January 1, 2020 through December 31, 2020 (instead of through the end of the performance period on December 31, 2021) did not exceed the threshold performance goal.
(10)		In connection with Mr. Fitzgerald's offer of employment as the Executive Vice President and President, Interventional Cardiology, Mr. Fitzgerald was granted an equity incentive award in the form of non-qualified stock options, vesting in one single installment on January 1, 2023.
(11)		The DSU award for Mr. Mackey, granted for retention purposes, will vest in one single installment, on the second anniversary date of the grant.
(12)		On December 3, 2018, Mr. Mirviss was granted an award for retention purposes. The DSU award for Mr. Mirviss vests in five equal annual installments, beginning on the first anniversary of the date of grant. The option award for Mr. Mirviss vests in four equal annual installments, beginning on the first anniversary of the date of grant.

The following table sets forth information regarding stock options that were exercised and DSUs that vested for our NEOs during the year ended December 31, 2020:

All of our executive officers, including our NEOs, are eligible to participate in our defined benefit Executive Retirement Plan, as amended effective August 1, 2016. The Executive Retirement Plan is a defined benefit plan that is intended to provide a clear and consistent approach to managing retirement-eligible executive departures with a standard, mutually understood separation and post-employment relationship. The plan provides retiring executives with a lump sum benefit of 2.5 months of salary for each year of service, up to a maximum of 36 months' pay. The lump sum payments are made in the first payroll period after the last day of the six-month period following retirement. Receipt of payment is conditioned upon the retiring employee entering into a separation agreement with us that includes a release of claims and customary non-disclosure, non-competition, non-solicitation and non-disparagement clauses in favor of the Company. The plan provides that in the event the executive breaches the non-competition or non-solicitation provision of his or her separation agreement, the executive must, in addition to any other court-ordered relief, repay to the Company all amounts paid under the plan.

To receive benefits under the plan, upon his or her retirement an executive's age plus his or her years of service with us must exceed 65 years (provided that the executive is at least 55 years old and has been employed by us for at least five years). For purposes of the plan, "retirement" means any separation from service (as defined in the plan) other than a termination for "cause" (defined as conviction of, or failure to contest prosecution for, a felony, or misconduct or dishonesty that is harmful to our business or reputation). In addition, if an executive dies and is otherwise eligible for benefits under the plan on the date of his or her death, benefits under the plan will be paid within 60 days of the executive's death.

For retirement-eligible NEOs as of December 31, 2020 (Messrs. Brennan, Mahoney, Fitzgerald, and Mirviss), the present value of accrued benefits is calculated as the value of their lump sum benefit under the plan based on the NEO's base salary, age and number of years of credited service as of December 31, 2020. For our NEO who was not eligible for retirement as of December 31, 2020 (Mr. Mackey, who will be retirement eligible in 2021), the present value of accrued benefits is

calculated based on the respective NEO's base salary, age and number of years of credited service as of December 31, 2020, discounted to December 31, 2020 from the earliest retirement eligibility date, using a discount rate of 1.43% per year. This valuation methodology is consistent with the methodology we use for financial statement accounting purposes, except that NEOs are assumed to remain employed by us until their earliest retirement age under the plan (or their age on December 31, if eligible for retirement on that date). For financial statement accounting purposes, the valuation considers the probability that the executives will achieve retirement age. For a more detailed description of the assumptions used in valuing accrued benefits under the plan, please see Note A — Significant Accounting Policies to our 2020 consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020.

The table below shows the present value of accumulated benefits payable to each of our NEOs, including the numbers of years of service credited to each NEO, under our Executive Retirement Plan as of December 31, 2020.

The Boston Scientific Corporation Deferred Bonus Plan (the Deferred Bonus Plan) provides certain of our management, including our NEOs, an opportunity to defer a portion of their annual award under our Annual Bonus Plan. The Deferred Bonus Plan provides participants the opportunity to defer up to 75% of their annual award under our Annual Bonus Plan until the earlier of (i) termination of employment or (ii) an elected distribution date, such election to be made by June 30th of each year. Investment choices under the plan are generally the same as those under our 401(k) Retirement Savings Plan, except that, among other things, participants may not elect to invest in the BSC Stock Fund. Distributions under the plan are in either lump sum payments or annual installments over a period of two to five years, as specified by the participant. Under the Deferred Bonus Plan, Messrs. Fitzgerald and Mirviss elected to defer 75% of their 2018 and 2019 Annual Bonus Plan Awards. In April 2020, the Compensation Committee determined that no deferral elections would be permitted under the Deferred Bonus Plan for the 2020 Annual Bonus, if any, payable in 2021.

In September 2004, we committed to fund a special one-time contribution to our 401(k) Retirement Savings Plan for the benefit of our employees. In June 2005, we adopted an Excess Benefit Plan, a non-qualified deferred compensation plan designed to provide specific supplemental benefits to those employees who would have exceeded the 2004 Code contribution limits if the special contribution had been made to their 401(k) plan accounts. Accordingly, the historic Excess Benefit Plan was established to accept the "overflow" contributions resulting from the special one-time contribution on behalf of

participating employees, including certain of our NEOs. Investment choices under the historic Excess Benefit Plan are generally the same as those under our 401(k) Retirement Savings Plan, except that, among other things, executive officers may not elect to invest in the BSC Stock Fund. The investment elections are made by each participant and may be changed daily. Generally, a lump sum cash payment of their respective account balances under the plan is made to participants determined to be "specified employees," including certain of our NEOs, commencing no earlier than six months and one day following their "separation from service."

The table below shows the aggregate earnings and balances for each of our NEOs under our historic Excess Benefit Plan and Deferred Bonus Plan as of December 31, 2020.

The investment choices under the historic Excess Benefit Plan and the Deferred Bonus Plan and their annual rates of return for the year ended December 31, 2020 are contained in the following table.

All of our executives, including our NEOs, are eligible to participate in our Executive Retirement Plan. The Executive Retirement Plan is intended to provide a clear and consistent approach to managing executive departures with a standard mutually-understood separation and post-employment relationship. The benefits payable to our executives upon "retirement" under the Executive Retirement Plan, as well as the present value of amounts accrued thereunder as of December 31, 2020, are reflected in the table and the related footnotes and narrative to the section titled "Defined Benefit Retirement Plan." In addition, changes in the present value of the benefits under the Executive Retirement Plan from December 31, 2019 to December 31, 2020 are reflected in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column of the Summary Compensation Table. For further discussion of our Executive Retirement Plan, please see the footnotes and narrative to the table appearing in the section titled "Defined Benefit Retirement Plan."

We have entered into Change in Control Agreements with our executives, including our NEOs, and other key employees. Our Change in Control Agreements for our executives are limited to a three-year term and provide that if both a change in control occurs during the term of the agreement and the executive's employment is terminated either by us without "Cause" or by the executive for "Good Reason" (each as described below) during the two-year period following the change in control, then the executive would be entitled to receive a lump sum payment of three times the sum of (i) the executive's base salary and (ii) target incentive bonus (or prior year's bonus, if higher). Additionally, an executive would be entitled to receive a prorated target incentive bonus for the year in which his or her termination occurred, continuation of health, life insurance and other welfare benefits for up to three years, and reimbursement for up to $100,000 in legal fees and expenses incurred by an executive in disputing termination or enforcing rights under his or her Change in Control Agreement. Our Change in Control Agreements further provide that all equity awards granted to executives require both a change in control and a termination without Cause or resignation by the executive for Good Reason within two years after the change in control in order to accelerate vesting; provided, however, that if the surviving or acquiring entity in a change in control transaction does not provide for the substitution or assumption of outstanding equity awards, such outstanding awards will immediately become fully vested.

The Change in Control Agreements include a "best net" provision that requires a reduction in the amount of the severance paid to an executive if the reduction would result in a greater after-tax amount. In exchange for the benefits afforded under our Change in Control Agreements, our executives agree to certain non-disclosure restrictions, a two-year non-solicitation obligation and to execute and not revoke a release in favor of the Company. Executives, including our NEOs, who receive payments under our Change in Control Agreements cannot also receive payments and benefits under our Executive Retirement Plan or Severance Plan For Exempt Employees (the Severance Plan).

For purposes of our Change in Control Agreements, "Cause" generally means willfully engaging in criminal or fraudulent acts or gross misconduct that is demonstrably and materially injurious to us. "Good Reason" generally means, among other things, assignment of duties inconsistent with the executive's status as an executive or an adverse alteration of the executive's duties; a reduction in annual base salary or bonus or failure to increase salary at a rate commensurate with that of other key executives; an adverse change in long-term incentive opportunities; failure by the Company to

continue to provide comparable benefits or continue in effect, or continue the executive's participation in, any compensation plan in which the executive participates; the relocation of the executive's principal place of work more than 50 miles; or failure by the Company to obtain a satisfactory agreement from any successor entity to agree to perform the Change in Control Agreement.

Equity awards granted to our executives under our 2011 LTIP, as previously in effect and as amended, require both a change in control and a subsequent termination without Cause or resignation for Good Reason pursuant to the terms of our Change in Control Agreements for accelerated vesting where the surviving or acquiring entity assumes outstanding awards.

The terms of all service-based DSUs granted in 2020 to our employees, including our NEOs, provide that in the event that the employee's employment terminates:

Our 2011 LTIP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2011 Long-Term Incentive Plan."

Our TSR PSPs cover our executives, including our NEOs, and are administered by the Compensation Committee. Under our 2018, 2019, and 2020 TSR PSPs, if a participant's employment terminates due to death or disability prior to the end of the three-year performance period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program have been satisfied at the end of the three-year performance period as if the participant had been employed until the end of the three-year performance period. Under our 2018, 2019, 2020 TSR PSPs, if a participant's employment terminates due to retirement after December 31 in the year of grant and prior to the end of the three-year performance period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program have been satisfied at the end of the three-year performance period, on a prorated basis through the date of retirement; however, such awards will be forfeited in their entirety in the event that retirement occurs on or prior to December 31 in the year of grant.

Pursuant to the terms of our Change in Control Agreements, the TSR performance-based DSUs awarded to our executives require both a change in control and a subsequent termination without Cause or resignation for Good Reason for accelerated vesting where the surviving or acquiring entity assumes outstanding awards. Under our TSR PSPs and our Change in Control Agreements, if a change in control and a subsequent termination without Cause or resignation for Good Reason occurs after December 31 in the year of grant, but prior to the end of the three-year performance period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the

performance criteria under the program have been satisfied on the last day of the month preceding the date on which the change in control is consummated, on a prorated basis.

Our 2020 TSR PSP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Total Shareholder Return Performance Share Program."

Our FCF PSPs cover our executives, including our NEOs, and are administered by our Compensation Committee. Under our 2018, 2019 and 2020 FCF PSPs, if a participant's employment terminates (i) due to retirement after the end of the one-year performance period but prior to the end of the three-year service period, shares of our common stock will be issued in respect of the FCF performance-based DSUs as to which the performance criteria under the program have been satisfied, on a prorated basis through the date of retirement (however, such awards will be forfeited in their entirety in the event that retirement occurs prior to the end of the one-year performance period), or (ii) due to death or disability at any time before the end of the three-year service period, shares of our common stock will be issued in respect of the FCF performance-based DSUs as to which the performance criteria under the program have been satisfied as if the participant had been employed until the end of the three-year service period.

Pursuant to the terms of our Change in Control Agreements, the FCF performance-based DSUs awarded to our executives require both a change in control and a subsequent termination without Cause or resignation for Good Reason for accelerated vesting where the surviving or acquiring entity assumes outstanding awards. However, such awards will be forfeited in their entirety in the event of a change of control that occurs prior to the end of the one-year performance period.

Our 2020 FCF PSP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Free Cash Flow Performance Share Program."

Our 2020 Annual Bonus Plan is generally available to all U.S. salaried personnel not eligible for commissions under sales compensation plans, including our NEOs, and certain international employees working in positions designated by the Company as eligible to participate in the plan. To be eligible to receive their incentive award, participants generally must be employed by us on the date payments are made under the 2020 Annual Bonus Plan. However, in the event of death, retirement or certain involuntary terminations without cause, in each case, as described in the 2020 Annual Bonus Plan, participants may receive their performance incentive awards for the year on a prorated basis based on the percentage of the year the participant was employed by us and eligible to participate (subject to certain minimum months of service requirements). Grants of performance incentive awards to our NEOs under our 2020 Annual Bonus Plan are reflected in the Summary Compensation Table in the "Non-Equity Incentive Plan Compensation" column, and our 2020 Annual Bonus Plan is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Annual Bonus Plan," as well as the Compensation Discussion & Analysis section titled "Short-Term Incentives."

We maintain severance plans for eligible employees, including our NEOs, under which participants are entitled to receive certain payments and benefits for specified periods of time following a qualifying termination. Such benefits are only available in the event of involuntary terminations due to layoff, defined in the severance plan as termination of employment that the Company determines is either (i) due to an anticipated facility relocation or closing or a reduction of staffing levels where the employee has not refused a similar position (as such term is defined under the severance plan) with the Company, or (ii) resulting from an anticipated sale, merger or reorganization of our Company where the employee is not provided an opportunity to be employed in a similar position with the acquiring or resulting entity. Executives, including our NEOs, who are eligible to receive payments under our Executive Retirement Plan or who receive severance payments under a Change in Control Agreement are not also eligible to receive payments and benefits under our severance plans.

The Severance Plan provides that director level and above exempt employees, including certain of our NEOs, are eligible for:

Additionally, the Severance Plan provides that, in the event of certain involuntary terminations, employees eligible to participate in our Annual Bonus Plan may be entitled to a prorated bonus if such involuntary termination occurs on or after October 1 of a calendar year. The prorated bonus is calculated by multiplying the amount of the bonus an employee would have received for the calendar year, had he or she remained employed by the Company until the bonus payment date (or, if less, the target bonus) (Bonus), times a fraction, as follows:

Under the Severance Plan, the payment of severance benefits is subject to the Company's receipt of a release of claims. In addition, the maximum severance payment available under the plan is limited to twice the Code dollar limitation in effect for qualified plans for the calendar year immediately preceding the calendar year in which the termination occurs.

The following tables show potential payments to Messrs. Mahoney, Brennan, Fitzgerald, Mackey, Mirviss under existing agreements, plans or other arrangements, for various scenarios involving a change in control or termination of employment, in each case assuming the termination was effective before the end of the day on December 31, 2020 and, where applicable, using the closing price of our common stock of $35.95 per share on December 31, 2020. In each case, amounts in these tables do not include amounts payable, if any, to our NEOs who were not retirement eligible on December 31, 2020 pursuant to our Executive Retirement Plan, which are described in the table and accompanying narrative and footnotes in the section titled "Defined Benefit Retirement Plan."

(1)		Employees, including NEOs, are not entitled to any benefits upon termination for cause. All unvested equity awards, as well as all vested but unexercised stock options, are forfeited as of the date of termination for Cause.
(2)		No benefits were payable upon voluntary termination by our NEOs as of December 31, 2020, unless the NEO was retirement eligible. Messrs. Mahoney, Brennan, Fitzgerald, and Mirviss were retirement eligible as of December 31, 2020.
(3)		Amounts in this column represent benefits payable upon involuntary termination by the Company on December 31, 2020 (other than termination for cause or in connection with a change in control). Amounts for Mr. Mackey represent benefits payable pursuant to our 2020 Annual Bonus Plan and the Severance Plan only in the event of certain involuntary terminations under the plans where he is not otherwise offered similar employment within the Company. Amounts for Messrs. Mahoney, Brennan, Fitzgerald, and Mirviss represent benefits payable pursuant to our 2020 Annual Bonus Plan and Executive Retirement Plan. Because Messrs. Mahoney, Brennan, Fitzgerald, and Mirviss are eligible to receive benefits under the Executive Retirement Plan, they are not eligible for any payments of benefits under the Severance Plan.
(4)		All equity awards granted to our executives require both a change in control and subsequent termination (without Cause or by the executive for Good Reason) in order to accelerate vesting; provided, however, that if the surviving or acquiring entity in a change in control transaction does not provide for the substitution or assumption of outstanding equity awards, such outstanding awards will immediately become fully vested. Amounts in the "Change in Control" column assume that the executive is not terminated subsequent to a change in control and that the surviving or acquiring entity in a change in control transaction provides for the substitution or assumption of outstanding equity awards.
		Amounts in the "Termination Following Change in Control" column represent benefits payable under our Change in Control Agreements following termination without Cause or resignation by the executive for Good Reason on December 31, 2020 in connection with, and within two years of, a change in control of the Company. For a further description of our Change in Control Agreements, please see the section titled "Change in Control Agreements" in the narrative to these tables.


(5)		Amounts in the "Pro rata Target Bonus" row represent the assumed on-plan bonus under our 2020 Annual Bonus Plan, which is equal to the incentive target amount under the plan, for each of our NEOs.
		Under the 2020 Annual Bonus Plan, participants generally must be employed by us on the date payments are made in order to be eligible for their incentive award. However, in the event of death, retirement or certain involuntary terminations without cause, participants generally may receive their performance incentive awards for the year on a prorated basis based on the percentage of the year the participant was employed by us and eligible to participate (subject to certain minimum months of service requirements). For a further description of our 2020 Annual Bonus Plan, please see the "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2020 Annual Bonus Plan," as well as the Compensation Discussion & Analysis section titled "Short-Term Incentives."
(6)		In determining the value of health and welfare benefits, we used the assumptions used for financial reporting purposes under GAAP.
(7)		Amounts in the "Executive Retirement Plan" row represent amounts earned under our Executive Retirement Plan, provided the NEO is eligible for benefits under the plan. In order to be eligible for benefits under the plan, the sum of an executive officer's age and years of service must equal 65, provided that the executive is at least 55 years old and has completed at least five years of service with us. Messrs. Mahoney, Brennan, Fitzgerald, and Mirviss were eligible for benefits under the plan on December 31, 2020.
(8)		Amounts in the "Other Benefits" row represent payment of outplacement services under the Severance Plan.
(9)		Amounts in the "Value of Accelerated Stock Options" row represent the number of shares underlying in-the-money unvested stock options held by each NEO, multiplied by the difference between that option's exercise price and $35.95 (the closing price of our common stock on December 31, 2020).
(10)		Amounts in the "Value of Accelerated Deferred Stock Units" row represent the value of the number of each NEO's performance and service-based DSUs, the vesting of which would have accelerated as of December 31, 2020, calculated by multiplying the number of accelerated DSUs by $35.95 (the closing price of our common stock on December 31, 2020).
		In February 2018, each of our NEOs was awarded TSR performance-based DSUs under our 2018 TSR PSP, the attainment of which was based on the TSR of our common stock relative to the TSR of the common stock of the other companies in the S&P 500 Healthcare Index over a three-year performance period. As of December 31, 2020, the performance and concurrent service period had been completed, and each NEO became entitled to 78% of the target number of TSR performance-based DSUs he was granted under the program in February 2018. The values of the awards to our NEOs under our 2018 TSR PSP are included in the tables above.
		In February 2019 and 2020, each of our NEOs was awarded TSR performance-based DSUs under our 2019 and 2020 TSR PSPs, respectively, the attainment of which will be based on the TSR of our common stock relative to the TSR of the common stock of the other companies in the S&P 500 Healthcare Index over a three-year performance and service period (Performance Period). Under the 2019 and 2020 TSR PSPs, if (a) a participant is terminated without Cause or resignation for Good Reason following a change in control after December 31 in the year of grant but prior to the end of the Performance Period or (b) a participant's employment terminates due to retirement after December 31 in the year of grant but prior to the end of the Performance Period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program had been satisfied, as of (x) for (a) above, the last day of the month preceding the date on which the change in control is consummated and (y) for (b) above, the end of the Performance Period, in each case prorated based on the number of months worked during the Performance Period, rounded to the nearest whole month. In addition, under our 2019 and 2020 TSR PSPs, if a participant's employment is terminated due to death or disability before the end of the Performance Period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program has been satisfied at the end of the Performance Period, as if the participant had been employed through the end of the Performance Period.


		If a NEO's employment was terminated without Cause or if the NEO resigned for Good Reason following a change in control on December 31, 2020, (a) the awards under our 2019 TSR PSP would accelerate, subject to proration as described in the foregoing paragraph, at 0% of target because the Company's TSR performance during the period beginning January 1, 2019 and ended December 31, 2020 ranked 51^st compared to its 57 peers for that period, and (b) the awards under our 2020 TSR PSP would be forfeited because the change in control did not occur after December 31 in the year of grant. Because we have not yet reached the end of the Performance Period for the awards under the 2019 and 2020 TSR PSPs, we are unable to ascertain with certainty the value of the TSR performance-based DSUs the NEOs would be entitled to in the event of retirement, death or disability on December 31, 2020. In such events, assuming that the Company's performance at the end of the Performance Period is the same as for the one- and two-year periods ended December 31, 2020, (a) the awards under our 2019 TSR PSP would accelerate, subject to proration as described in the foregoing paragraph, at 0% of target, and (b) the awards under our 2020 TSR PSP would accelerate, subject to proration as described in the foregoing paragraph, at 0% of target because the Company's TSR performance during the period beginning January 1, 2020 and ended December 31, 2020 ranked 57^th compared to its 57 peers for that period.
		For a discussion of the actual performance under our 2018, 2019 and 2020 TSR PSPs, please see the footnotes to the table appearing in "Outstanding Equity Awards At Fiscal Year End."
		In February 2018, 2019, and 2020, each of our NEOs was awarded FCF performance-based DSUs under our 2018 FCF PSP, 2019 FCF PSP and 2020 FCF PSP, respectively. Our adjusted free cash flow performance in 2018 was 108.9% relative to our 2018 internal financial plan; accordingly, in February 2019, the Compensation Committee determined that pursuant to the terms of the 2017 FCF PSP, 117.9% of the target number of FCF performance-based DSUs had been earned under the program. Our adjusted free cash flow performance in 2019 was 93.4% relative to our 2019 internal financial plan; accordingly, in February 2020, the Compensation Committee determined that pursuant to the terms of the 2019 FCF PSP, 90.1% of the target number of FCF performance-based DSUs had been earned under the program. Our adjusted free cash flow performance in 2020 was 94.3% relative to our 2020 internal financial plan; accordingly, in February 2021, the Compensation Committee determined that pursuant to the terms of the 2020 FCF PSP, 88.6% of the target number of FCF performance-based DSUs had been earned under the program. All of such units were subject to the satisfaction of the service criteria over a three-year period (inclusive of the performance period). Under the 2018, 2019, 2020 FCF PSPs, if a participant's employment terminates due to retirement after the performance period but prior to the end of the three-year service period, shares of our common stock will be issued in respect of the FCF performance-based DSUs as to which the performance criteria under the program have been satisfied on a prorated basis based on the number of months worked during the three-year service period, rounded to the nearest whole month, and if a participant's employment terminates due to death or disability before the end of the three-year service period, shares of our common stock will be issued in respect of the FCF performance-based DSUs as to which the performance criteria under the program have been satisfied, as if the participant had been employed through the end of the three-year service period. Additionally, pursuant to the terms of our Change in Control Agreements, the vesting of FCF performance-based DSUs awarded to our executives will be accelerated on a pro rata basis based on the number of months worked during the three-year service period, rounded to the nearest whole month in the event of both a change in control and a subsequent termination without Cause or resignation for Good Reason.

We strive to pay our employees competitively compared to similar positions in the applicable labor market. We follow that approach worldwide, whether for an executive position or an hourly job at a local facility. We take into account location, job level and pay grade, time with us and time in current role, experience and skill set, and adjust compensation annually to match the applicable market. By doing so, we believe we maintain a high-quality, stable workforce. We determined the compensation we paid to the median employee in accordance with this philosophy.

Under rules adopted pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to calculate and disclose the total compensation paid to our median employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to Michael F. Mahoney, our CEO. The following paragraphs describe our methodology and the resulting CEO Pay Ratio.

Based on this information, for 2020 the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees (other than our CEO) was estimated to be approximately 232 to 1.

The pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described below. The SEC rules for identifying the "median employee" and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported by us, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their pay ratios.

To identify the median of the annual total compensation of all our employees and the annual total compensation of the median employee, the methodology and the material assumptions, adjustments and estimates that we used were as follows:

Section 14A of the Exchange Act requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of the named executive officers as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. Our Board has determined to provide our stockholders this opportunity on an annual basis and we expect the next vote to be held at our 2022 annual meeting of stockholders.

As described in the Compensation Discussion & Analysis, our executive compensation philosophy is to provide appropriate competitive compensation opportunities to our executives with actual pay outcomes heavily influenced by the achievement of Company performance targets and individual performance objectives (in other words, "pay for performance") in support of our business strategy and creation of long-term stockholder value.

Our Compensation Committee believes that a strong foundation for our compensation program is necessary to execute our executive compensation philosophy effectively. The following key aspects of executive compensation best practices serve as the foundation for our compensation program:

We believe our emphasis on at-risk, performance-based incentive compensation — consisting of our Annual Bonus Plan awards and long-term equity awards — aligns our executives with our business strategy and the short- and long-term interests of our stockholders, providing "pay for performance" and putting a significant portion of our executives' pay "at risk."

A Significant Portion of our NEOs' 2020 Target TDC is At-Risk, Performance-Based Compensation

Our Compensation Committee ties a significant portion of the primary elements of our executives' target TDC to at-risk, performance-based incentive opportunities. For 2020, approximately 90.8% of the target value of the primary elements of TDC for our CEO and approximately 80.3% of the target value of the primary elements of TDC for our other NEOs, as a group, consisted of at-risk,

performance-based incentive compensation. For additional details and a breakdown of at-risk, performance-based incentive compensation, please see the Compensation Discussion & Analysis sections titled "A Significant Portion of our NEOs' 2020 Target TDC is At-Risk, Performance-Based Compensation" and "Elements of 2020 Executive Compensation, Primary Elements of Total Direct Compensation."

Accordingly, we ask our stockholders to vote "FOR" the following resolution at the Annual Meeting:

"RESOLVED, that the Company's stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company's Proxy Statement for the 2021 Annual Meeting of Stockholders pursuant to Item 402 of Regulation S-K, including the Compensation Discussion & Analysis, compensation tables and narrative discussion."

While the vote is advisory in nature, which means that it is non-binding on us, our Compensation Committee values the opinions of our stockholders and will take into consideration the outcome of the vote when considering future executive compensation arrangements. We currently conduct annual advisory votes on executive compensation, and, therefore, we intend to hold the next advisory vote to approve the compensation of the named executive officers at our 2022 Annual Meeting of Stockholders.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO ITEM 402 OF REGULATION S-K.

The following table summarizes information as of December 31, 2020 relating to our equity compensation plans pursuant to which grants of stock options, deferred stock units, restricted stock grants or other rights to acquire shares may be granted from time to time.


(1)		Amounts in columns (a) and (b) include outstanding options under our 2000, 2003 and 2011 LTIPs. Our 2000 LTIP expired on February 28, 2010 and our 2003 LTIP expired on June 1, 2011; however, awards made under these plans still remain outstanding. The amount in column (a) also includes 9,728,885 shares awarded under our 2000, 2003 and 2011 LTIPs in the form of service-based DSUs, Company performance-based DSUs and restricted stock. Of such amount, approximately 912,594 shares are issuable upon settlement of outstanding Company performance-based DSUs. Shares underlying the 2018, 2019 and 2020 TSR performance-based DSUs are earned over a three-year performance and service period. The 2018 TSR performance-based DSUs have been included based on actual performance. The 2019 TSR performance-based DSUs have been included assuming threshold achievement of the Company performance criteria and achievement of the individual service criteria of the program (40% of the target units awarded). We have included the number of shares underlying the threshold number of units in column (a) because the Company's TSR performance during the two-year period from January 1, 2019 through December 31, 2020 under the 2019 TSR PSP was below the threshold level of performance under the program. The 2020 TSR performance-based DSUs have been included assuming threshold achievement of the Company performance criteria and achievement of the individual service criteria of the program (40% of the target units awarded). We have included the number of shares underlying the threshold number of units in column (a) because the Company's TSR performance during the one-year period from January 1, 2020 through December 31, 2020 under the 2020 TSR PSP was below the threshold level of performance under the program. Shares underlying the 2018, 2019 and 2020 FCF performance-based DSUs have been included at 117.9%, 90.1% and 88.6% of target, respectively, the actual number of units for which the performance criteria under the programs have been satisfied. Such units remain subject to the individual service criteria under the program.
(2)		This number reflects the exclusion of 9,728,885 shares in the form of service-based DSUs, Company performance-based RSUs and restricted stock granted pursuant to our equity plans included in column (a). These awards allow for the distribution of shares to the grant recipient upon vesting and do not have an associated exercise price. Accordingly, these awards are not reflected in the weighted-average exercise price.
(3)		This number reflects, as of December 31, 2020, the 72,807,983 shares available for issuance under our 2011 Amended and Restated LTIP. This number does not include 5,539,050 shares available for purchase by our employees under our GESOP, which are not available for grant in any other form.
(4)		We have acquired a number of companies over the past several years. From time to time, we have assumed the acquired company's incentive plan(s), including the outstanding stock options and warrants, if any, granted under those plan(s). No further stock options are outstanding under assumed plans and no additional stock options may be granted under the assumed plans beyond those assumed in connection with the acquisitions. Assumed stock options that terminate prior to expiration are not available for re-grant.

The Audit Committee oversees our Company's financial reporting process on behalf of the Board of Directors and has other responsibilities as set forth in the Audit Committee charter, which is available on our website at www.bostonscientific.com under the "Investor Relations" section. Management has the primary responsibility for our Company's financial statements and reporting process, including the systems of internal controls. Ernst & Young LLP (Ernst & Young), our independent registered public accounting firm for fiscal year 2020, is responsible for expressing an opinion on the conformity of our Company's audited financial statements with generally accepted accounting principles and on our Company's internal control over financial reporting.

In fulfilling its oversight responsibilities, the Audit Committee reviewed with management and Ernst & Young the audited financial statements included in the Boston Scientific Annual Report on Form 10-K for the year ended December 31, 2020, including a discussion about the quality, not just the acceptability, of our Company's accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements, and Ernst & Young's evaluation of the Company's internal control over financial reporting.

The Audit Committee also discussed with Ernst & Young the matters that are required to be discussed by the Public Company Accounting Oversight Board's Auditing Standard No. 1301, Communications with Audit Committees. Ernst & Young has also provided the Audit Committee the written disclosures and the letter 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 the Audit Committee has discussed with Ernst & Young that firm's independence. The Audit Committee has concluded that Ernst & Young's provision of audit and non-audit services to the Company and its affiliates is compatible with Ernst & Young's independence.

The Audit Committee further discussed with the Company's internal auditors and Ernst & Young the overall scope and plans for their respective audits. The Audit Committee meets at least quarterly with the internal auditors and Ernst & Young, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting.

Based on the reviews and discussions referred to above, the Audit Committee approved the inclusion of the audited financial statements in the Annual Report on Form 10-K for the year ended December 31, 2020, which has been filed with the Securities and Exchange Commission. The Audit Committee has also approved the selection of Ernst & Young as the Company's independent registered public accounting firm for fiscal year 2021.

This Audit Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Boston Scientific filing with the SEC, except to the extent that Boston Scientific specifically incorporates this Report by reference into another Boston Scientific filing.

PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has appointed Ernst & Young LLP as our independent registered public accounting firm for the 2021 fiscal year. The Audit Committee is directly responsible for approving the appointment, retention and compensation, and for the oversight of the work of our independent registered public accounting firm (including resolution of disagreements between management and the independent registered public accounting firm regarding financial reporting) for the purpose of preparing or issuing an audit report or related work. Ernst & Young LLP has been retained as the Company's external auditor continuously since 1992. The Audit Committee is responsible for audit fee negotiations associated with the Company's retention of Ernst & Young LLP. In order to assure continuing auditor independence, the Audit Committee periodically considers whether there should be a regular rotation of the independent external audit firm. In conjunction with the mandated rotation of the Audit Firm's lead engagement partner, the Audit Committee and its chair are directly involved in the selection of Ernst & Young LLP's new lead engagement partner.

In making its determination regarding whether to appoint or retain a particular independent registered public accounting firm, the Audit Committee takes into account the views of management and our internal auditors, and will take into account the vote of our stockholders with respect to the ratification of the selection of our independent registered public accounting firm. The members of the Audit Committee and the Board believe that the continued retention of Ernst & Young LLP to serve as the Company's independent registered public accounting firm is in the best interests of the Company and its investors.

Representatives of Ernst & Young LLP are expected to virtually attend the Annual Meeting and respond to questions and, if they desire, make a statement.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE 2021 FISCAL YEAR.

The following table presents the aggregate fees billed for professional services rendered by Ernst & Young LLP for the fiscal years ended December 31, 2019 and December 31, 2020.

It is the Audit Committee's policy to approve in advance the types and amounts of audit, audit-related, tax and any other services to be provided by our independent registered public accounting firm. In situations where it is not possible to obtain full Audit Committee approval, the Audit Committee has delegated authority to the Chair of the Audit Committee to grant pre-approval of auditing, audit-related, tax and all other services. Any pre-approved decisions by the Chair are required to be reviewed with the Audit Committee at its next scheduled meeting. The Audit Committee approved all of Ernst & Young LLP's services for 2019 and 2020 and, in doing so, considered whether the provision of such services is compatible with maintaining independence.

We have been notified by an asset manager, the beneficial owner of more than $2,000 worth of shares of our common stock, that it intends to present the following proposal for consideration at the Annual Meeting. We will provide the name and address of the stockholder proponent promptly upon receiving an oral or written request to the Company's Corporate Secretary at the address and phone number listed on page 1 of this Proxy Statement. The stockholder proposal will be voted on at the Annual Meeting only if properly presented by or on behalf of the stockholder proponent.

WHEREAS: In 2019, the Business Roundtable, an association of chief executive officers of America's leading companies, issued a new Statement on the Purpose of a Corporation which emphasized "a fundamental commitment to all of our stakeholders" including employees;

Coupled with a worldwide increased interest in environmental and social considerations, this new focus on "stakeholder capitalism" can be understood to imply that a company's fiduciaries must address or reflect the interests of all stakeholders;

However, observers have struggled to find evidence that signatories have used the Statement to revise corporate policies or actions. Recently JUST Capital found that "while 72% of respondents believe corporate leaders are serving shareholders well, only 47% believe they're having a positive impact on the financial well-being of their workers";

In 2018, the Accountable Capitalism Act was introduced into the U.S. Congress to combat "America's fundamental economic problems" such as companies' failure to reinvest proceeds in their operations, including employees. The Act would require that "boards ... include substantial employee participation ... ensur[ing] that no fewer than 40% of [a board's] directors are selected by the corporation's employees";

Furthermore, the World Economic Forum has stated that "[i]ssues that were previously considered secondary for CEOs and boards — matters once handled by companies' stakeholder-relations, philanthropy, and information-technology departments — have become important determinants of firms' capacity to create and sustain economic value ... The talent and motivation of a firm's workforce, an innovative corporate culture, individual know-how, and data all are becoming increasingly important sources of value";

Proponents believe that our company can advance long-term value creation through a board that includes non-management employee involvement in company governance.

RESOLVED: Shareholders of Boston Scientific Corporation urge the Board of Directors to prepare a report to shareholders describing any benefits to the company related to employee participation in company governance.

SUPPORTING STATEMENT: The report should be prepared within one year, at reasonable cost and excluding proprietary and privileged information. The Board is encouraged to assess:

For purposes of this proposal, the term "non-management employees" should be understood to be employees that are neither management nor company executives.

Our Board and the Nominating and Governance Committee have considered this proposal and concluded that its adoption is unnecessary and not in the best interests of our stockholders or employees.

Our independent Nominating and Governance Committee, along with the full Board, is best positioned to identify, evaluate and recommend director nominees.

Our Board is composed of a diverse group of leaders in their respective fields. As described in more detail in the "Corporate Governance — Director Nomination Process" section of this Proxy Statement, the Nominating and Corporate Governance Committee looks for several critical qualities in screening and evaluating potential director candidates to serve our stockholders. Many of our directors have senior leadership experience at major domestic and international companies. In these positions, they have gained experience in core management skills, such as strategic and financial planning, public company financial reporting, compliance, risk management, and international business. Most of our directors also have experience serving on the boards of directors and board committees of other public companies and have an understanding of corporate governance practices and trends and different business processes, challenges, and strategies.

Our independent Nominating and Governance Committee and the Board have developed criteria and a process for identifying and recommending director candidates for election by our stockholders. In undertaking this responsibility, the Nominating and Governance Committee has a fiduciary duty to act in good faith for the best interests of the Company and all of our stockholders. This process is designed to identify and nominate director candidates who possess a combination of skills, professional experience and diversity of backgrounds necessary to oversee our business and who can contribute to the overall effectiveness of our Board. Through this process, we believe that our Nominating and Governance Committee and Board are able to achieve the optimal balance of director skills and qualifications that best serve the Company and all of our stockholders.

Our Board is engaged with our employees through formal and informal avenues. As described in our Corporate Governance Guidelines, the Board encourages input from non-executive employees and the Board regularly receives presentations from, and interacts with, non-executive employees in the course of its normal meetings. For example, the Board interacts with leaders of our employee resource

groups, including when such leaders are invited to address the Board at its meetings and when Board members are invited to speak at employee resource group sponsored events, specifically to help facilitate our diversity and inclusion strategic imperative and goals, and to better understand the specific challenges and opportunities affecting our diverse employee population. In sum, the Board is actively engaged in overseeing the Company's culture to ensure alignment with its views and values.

We are consistently recognized as one of the world's most admired companies and best places to work. Our employees are the talented and dedicated force behind every milestone we achieve. Our top industry awards and rankings include Dow Jones Sustainability Index for North America, FORTUNE World's Most Admired Companies, Forbes America's Most Just Companies, Newsweek's America's Most Responsible Companies, Culture Champion 2020 MIT Sloan Management Review/Glassdoor, the Human Rights Campaign's Best Places to Work for LGBTQ Equality, Disability Equality Index (DEI) Best Places to Work for Disability Inclusion, Bloomberg-Gender Equality Index, NAFE Top Companies for Executive Women, and Working Mother Diversity Best Practices Inclusion Index. We actively engage with, and seek a diversity of perspectives from, our employees on various initiatives, including managing our corporate social responsibility (CSR) proposals, conducting global employee engagement surveys, and driving change though our diversity and inclusion strategies. Details of these initiatives can be found in our Performance Report, which can be found here: https://www.bostonscientific.com/content/dam/bostonscientific/corporate/citizenship/sustainability/2019_Boston_Scientific_Performance_Report.pdf. We recognize that in 2019, the Business Roundtable (BRT) published a statement which has been the subject of considerable debate and opposition by entities like the Council of Institutional Investors. The statement describes revised BRT principles that focus on a mix of stakeholders, including employees, customers, suppliers, the environment, communities and shareholders. We believe that the fundamental culture of the Company as well as the dynamic efforts undertaken by the Board and the Company as this landscape evolves match up well with the revised BRT principles.

Our stockholders and employees have the ability to communicate directly with the Board.

We pride ourselves on incorporating feedback from all stakeholders, including our employees, into our decision-making process at the Board and management level. We have multiple channels through which employees can provide feedback to management, and we believe this open communication is key in collecting valuable data that are factored into our decisions. See "Corporate Governance — Communications with the Board" section of this Proxy Statement and our Performance Report. We note that, based on input from our stockholders and benchmarking of corporate governance best practices, the Board adopted (i) proxy access, a process by which stockholders meeting certain requirements can nominate directors for election using the Company's proxy statement, (ii) a majority voting standard in director elections, and (iii) a requirement that women and racially/ethnically diverse candidates are among the initial slate of candidates presented for consideration in external searches for a Chief Executive Officer and new Board members.

Our stockholders can recommend prospective director candidates for the Nominating and Governance Committee's consideration.

As discussed above, the Nominating and Governance Committee will also consider director nominees proposed by our stockholders and other sources. Nominees proposed by stockholders for the Committee's consideration are considered and evaluated with the same degree of care and consideration as a nominee recommended by an independent Board member and our Chairman and Chief Executive Officer. Our Board believes the director nominating and evaluation process already allows the best and most qualified candidates to be elected to the Board.

For the reasons explained above, our Board recommends that stockholders vote "AGAINST" this proposal.

The affirmative vote of a majority of shares with voting power present in person or represented by proxy and which have actually voted on the proposal is required to approve the stockholder proposal described in this Proxy Statement. You may vote "FOR," "AGAINST" or "ABSTAIN." If you "ABSTAIN," it will be counted for the purpose of determining whether a quorum is present for conducting the Annual Meeting, but your vote will not count as a share actually voted with respect to determining if a majority vote is obtained and will have no effect on the determination of this proposal.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
YOU VOTE "AGAINST" THE STOCKHOLDER PROPOSAL.

In accordance with Rule 14a-8 under the Exchange Act and the advance notice provisions of our By-Laws, stockholder proposals and director nominations for the 2022 Annual Meeting of Stockholders must be received by our Corporate Secretary at our principal executive office on or before November 24, 2021. Under the proxy access by-law provisions of our By-Laws, director nominations submitted for inclusion in our 2022 Annual Proxy Statement must be received no earlier than October 25, 2021 and no later than November 24, 2021. Director nominations by our stockholders must also satisfy the other procedures and requirements set forth in the advance notice and proxy access provisions of our By-Laws, as appropriate. Any proposals or nominees received after this date will be considered untimely under Rule 14a-8 under the Exchange Act and the advance notice provisions of our By-Laws.

Should you wish to submit a proposal or director nomination, have it addressed to our Corporate Secretary at Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752. In order to be considered for inclusion in next year's Proxy Statement, proposals must also satisfy the other procedures set forth in Rule 14a-8 under the Exchange Act. Proposals that are submitted outside of Rule 14a-8, as well as director nominees, for presentation at our 2022 Annual Meeting of Stockholders, but that will not be included in next year's Proxy Statement, must also satisfy the procedures set forth in the advance notice provision of our By-Laws.

Our 2020 Annual Report to Stockholders, including financial statements for the fiscal year ended December 31, 2020, accompanies this Proxy Statement. The Annual Report is also available on our website at www.bostonscientific.com under "Financials & Filings" in the "Investor Relations" section. Copies of our 2020 Annual Report on Form 10-K, which is on file with the SEC, are available to any stockholder free of charge who submits a request in writing to Investor Relations, Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752, or by calling (508) 683-5670. Copies of any exhibits to the Form 10-K are also available upon written request and payment of a fee covering our reasonable expenses in furnishing the exhibits.

Applicable rules permit us and brokerage firms to send one Notice or Proxy Statement and Annual Report to multiple stockholders who share the same address unless we have received instructions to the contrary from one or more of the stockholders. This practice is known as householding. If you hold your shares through a broker, you may have consented to reducing the number of copies of materials delivered to your address. In the event that you wish to revoke a householding consent you previously provided to a broker, you must contact that broker to revoke your consent. If you (i) are eligible for householding and you currently receive multiple copies of either our Notice or Proxy Statement and our Annual Report but you wish to receive only one copy of each of these documents for your household or (ii) you currently receive only one set of these documents due to householding and wish to revoke your consent for future mailings, please contact Broadridge Financial Solutions, Inc. by mail at Householding Department, Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, New York 11717 or by telephone at (800) 542-1061.

If you are currently subject to householding and wish to receive a separate Proxy Statement or Annual Report, you may find these materials on our website at www.bostonscientific.com under "Financial Information" in the "Investor Relations" section. You may also request printed copies of our Notice or Proxy Statement and Annual Report free of charge by contacting Investor Relations, Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752, or by calling (508) 683-5670. We will deliver promptly, upon written or oral request, a separate copy of the Notice, Proxy Statement or Annual Report to a stockholder at a shared address to which a single copy of the documents was delivered.

We do not know of any other matters that may be presented for consideration at the Annual Meeting. If any other business is properly presented for consideration before the Annual Meeting, the persons named as proxies on the enclosed proxy card, or proxy voting instruction form, will vote as they deem in the best interests of the Company.

We will pay the costs of this solicitation. Our directors, officers or other employees may solicit proxies on behalf of the Board primarily by mail and via the Internet, but additional solicitations may be made in person, by electronic delivery, telephone, facsimile or other medium. No additional compensation will be paid to our directors, officers or other employees in connection with this solicitation. We may enlist the assistance of brokerage houses, fiduciaries, custodians and other third parties in soliciting proxies. We will, upon request, reimburse brokerage firms and other third parties for their reasonable expenses incurred for forwarding solicitation material to beneficial holders of our common stock. We have also retained Alliance Advisors, a proxy solicitation firm, to assist in the solicitation of proxies, as need be, for a fee of $12,500, plus reimbursement of expenses. All solicitation expenses, including costs of preparing, assembling and mailing proxy materials, will be borne by us.

Information on or connected to our website (or the website of any third party) referenced in this Proxy Statement is in addition to and not a part of or incorporated by reference into this Proxy Statement. Such additional information speaks as of the date thereof and is not intended to be confirmed or updated by reference herein. Boston Scientific disclaims any liability or responsibility for or endorsement of the information on or connected to the website of a third party.

Reconciliations of GAAP Financial Measures to Non-GAAP Financial Measures Used as
Performance Metrics Under Certain of Our Short- and Long-Term Incentive Compensation Plans and Programs²

The following is a reconciliation of cash provided by operating activities prepared in accordance with generally accepted accounting principles in the United States (GAAP) to adjusted free cash flow as used in our 2020 Free Cash Flow Performance Share Program (2020 FCF PSP).

The following is a reconciliation of net sales prepared in accordance with GAAP to adjusted net sales as used in our 2020 Annual Bonus Plan:

The following is a reconciliation of earnings per share prepared in accordance with GAAP to adjusted earnings per share as used in our 2020 Annual Bonus Plan:

	2020


GAAP earnings (loss) per share available to common stockholders	$	(0.08	)
Non-GAAP adjustments:
Amortization expense		0.49
Goodwill and other intangible asset impairment charges		0.32
Acquisition-/divestiture-related net charges (credits)		0.08
Restructuring and restructuring-related net charges (credits)		0.10
Litigation-related net charges (credits)		0.18
Investment portfolio net losses (gains)		(0.23	)
EU MDR implementation costs		0.02
Deferred tax expenses (benefits)		0.03
Discrete tax items		0.05

Adjusted earnings (loss) per share	$	0.96

To supplement our consolidated financial statements presented on a GAAP basis, we disclose certain non-GAAP financial measures. To describe the relationship between pay and performance, we disclose certain non-GAAP financial measures used as performance metrics under certain of our short- and long-term incentive compensation plans and programs, including adjusted free cash flow, adjusted net sales and adjusted earnings per share (EPS). These non-GAAP financial measures are not in accordance with generally accepted accounting principles in the United States (GAAP) and should not be considered in isolation from or as a replacement for the most directly comparable GAAP financial measures.

Management uses these supplemental non-GAAP financial measures to evaluate performance period over period, to analyze the underlying trends in our business, to assess our performance relative to our competitors, and to establish operational goals and forecasts that are used in allocating resources. In addition, management uses these non-GAAP financial measures to further its understanding of the performance of our operating segments.

Adjusted earnings (loss) per share excludes certain charges (credits) included in GAAP earnings (loss) per share available to common available to common stockholders as we believe these items are not indicative of future performance. Please refer to Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission for an explanation of each of these adjustments and the reasons for excluding each item. These amounts are excluded by management in assessing our performance, as well as from our operating segments' measures of profit and loss used to make operating decisions and assess their performance. Accordingly, management excluded these items in calculating this non-GAAP financial measure under our 2020 Annual Bonus Plan to facilitate an evaluation of our performance relative to our internal financial plan in accordance with the 2020 Annual Bonus Plan.

Adjusted free cash flow as used in our 2020 FCF PSP is a non-GAAP measure that excludes net purchases of property plant and equipment, as well as the cash component of certain charges (credits) that are excluded from adjusted net income (loss) in addition to any cash tax benefits of such charges. Further, we exclude tax settlement payments that relate to prior periods. The GAAP measure that is most directly comparable to adjusted free cash flow is cash provided by operating activities. Accordingly, management excluded or included these cash items for purposes of reviewing our cash flow performance in calculating this non-GAAP financial measure under our 2020 FCF PSP to facilitate an evaluation of our cash flow performance relative to our internal financial plan in accordance with the 2020 FCF PSP.

Adjusted net sales as used in our 2020 Annual Bonus Plan excludes the impact of foreign currency fluctuations included in our GAAP net sales to align with measures that are considered by management to evaluate performance relative to our operating plan. Management excluded the impact of foreign currency fluctuations, which are highly variable and difficult to predict, by converting actual net sales from local currency to U.S. dollars using internally derived constant foreign currency exchange rates in the current and prior period. The GAAP financial measures most directly comparable to adjusted net sales is net sales on a GAAP basis.

We believe that presenting the non-GAAP financial measures that are used as performance metrics under certain of our short- and long-term incentive compensation plans and programs, in addition to the corresponding GAAP financial measures, provides investors greater transparency to information relevant to the relationship between pay and performance and allows investors to see our results "through the eyes" of management.

(4)		Each non-employee director elected at our 2020 Annual Meeting of Stockholders was granted an equity award with a value of $185,000. For each director that elected to receive restricted stock, the restricted stock vests on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continued service during such term. For each director that elected to receive deferred stock units, the deferred stock units vest on the date of the annual meeting of stockholders immediately following the date of grant, subject to continued service during such term, and vested shares of stock will be issued to the director upon his or her separation from Board service in accordance with the 2014 Non-Employee Director Deferred Compensation Plan.


		The annual equity awards to our directors during 2020 are shown below:


		The outstanding Restricted Stock, Restricted Stock Deferred and Deferred Stock Units held by the non-employee directors at December 31, 2020 are shown below:

(5)		The outstanding, unexercised stock options at December 31, 2020, pursuant to stock option awards previously granted to non-employee directors, all of which have vested, are shown below.


(6)		The amounts in this column represent the "above-market" portion of 2020 earnings under the interest crediting investment option available under the Non-Employee Director Deferred Compensation Plan. The interest rate used under the plan each year is the Moody's Composite Yield on Seasoned Corporate Bonds for the month of September of the preceding year. For 2020, the interest rate used under the plan was 3.38%, the Moody's rate in September 2019. Under SEC rules, interest on non-qualified deferred compensation is considered "above-market" if the interest rate exceeds 120% of the federal long-term interest rate, with compounding at the rate that corresponds most closely to the rate under the plan, at the time the interest rate or formula is set. For 2020, 120% of the applicable federal long-term interest rate was 2.66%.

(2)		2020 Target and Actual Bonus Plan Awards are rounded to the nearest thousand.


(1)		Under our 2011 Long-Term Incentive Plan, these awards are called deferred stock units, or DSUs.
