LETTER TO SHAREHOLDERS

DEAR FELLOW SHAREHOLDERS,

As 2020 began, the world was presented with a major crisis as the SARS-CoV-2 (COVID-19) pandemic spread across the globe. Regeneron mobilized quickly, realizing that we were uniquely suited to bring forward potential solutions. We are extremely proud of how our talented team is responding to this public health challenge. Given our more than 30 years of investment in core technologies that improve the drug discovery and development process, and our track record of success with infectious diseases like Ebola, we are optimistic that we can make a meaningful and timely impact. We have two important COVID-19 research and development efforts ongoing: a global clinical trial of our IL-6 inhibitor Kevzara®(sarilumab) in hospitalized patients with severe or critical COVID-19; and the development of a novel antibody cocktail specifically designed to prevent or treat COVID-19 infection. We will be sharing updates on these programs as quickly as possible over the coming weeks and months.

Now, more than ever, we must remain focused on our mission to repeatedly bring important new medicines to patients with serious diseases. In 2019 we had a year of strong performance and delivery on this mission. We reached more and more patients through newly-approved indications and record growth for our blockbuster treatments EYLEA®(aflibercept) Injection and Dupixent®(dupilumab), made significant advancements throughout our preclinical and clinical pipelines, and delivered a public health breakthrough with an effective treatment for Ebola which is currently under review by the U.S. Food and Drug Administration.

Total revenues for 2019 were $7.9 billion, a 17 percent increase over 2018, which included U.S. EYLEA net product sales of $4.6 billion. Our collaborator Bayer recorded net product sales for EYLEA outside the U.S. of $2.9 billion, bringing EYLEA’s total global net product sales to $7.5 billion, a 12 percent increase compared to 2018. These figures show the continuing strength of this important treatment that has had double-digit sales growth for seven years without a single price increase. We remain confident in EYLEA’s ability to help even more patients as we expand our leadership position in wet age-related macular degeneration and diabetic eye diseases. Dupixent 2019 global net product sales, which are recorded by Sanofi, were $2.3 billion, an increase of 151 percent over the previous year. We have just begun to tap the potential of this first-in-class treatment option for several Type 2 inflammatory diseases, with many more studies underway.

In part due to Dupixent’s strong sales, our antibody collaboration with Sanofi became profitable for the first time in 2019, and we took important additional steps to strengthen Regeneron’s financial position. In the second quarter of 2020 we restructured our Antibody Collaboration with Sanofi to enhance profitability further and to simplify the commercial strategy for Praluent®(alirocumab). We will continue to collaborate with Sanofi on studying Kevzara for COVID-19, with Regeneron leading U.S.-based development and Sanofi leading development outside of the United States.

Meanwhile our research and development productivity continues, with notable progress in our growing immuno-oncology portfolio and diversification across the pipeline as a whole. We expanded our clinical program with Libtayo®(cemiplimab-rwlc), a PD-1 inhibitor, and moved multiple bispecific antibodies into the clinic, including the first in a whole new class of co-stimulatory bispecifics, which position us to become a leader in this emerging field. We continue to explore Dupixent in a variety of additional Type 2 inflammatory conditions, with late-stage trials underway in eosinophilic esophagitis, chronic obstructive pulmonary disease, prurigo nodularis, and chronic spontaneous urticaria, as well as earlier studies in grass and food allergies.

From a public health perspective, we made a breakthrough in the fight against the devastating Ebola outbreak in the Democratic Republic of the Congo (DRC) with REGN-EB3’s impressive reduction in mortality compared to the prior

Dear Shareholders, 2015 was a busy and rewarding year for Regeneron as we made major strides in advancing our mission of bringing important new medicines to people with serious diseases, over and over again. We delivered EYLEA® (aflibercept) Injection, our therapy for patients with serious vision-threatening diseases, to more and more patients, and we launched PRALUENT® (alirocumab) Injection, a first-in-class therapy for uncontrolled LDL cholesterol in certain patients. Our pipeline of a dozen clinical-stage antibodies continues to progress, with important programs in eye disease, cancer, infectious disease, pain, cardiovascular disease and inflammation. We also continue to invest in technology and innovation that will position us to bring needed new medicines to patients for many years into the future. Likewise, we have made important infrastructure investments to ensure our long-term success, including adding two new buildings at our headquarters in Tarrytown, New York, and expanding our industrial operations facilities in Rensselaer, New York, and Limerick, Ireland. We have always run Regeneron by the principle of “doing well by doing good.” In addition to our work to invent new and needed medicines, we focus on improving our world and operating with the highest standards of integrity. This year, for the first time, our Annual Review integrates reporting on our citizenship priorities and aspirations, in addition to our financial and business performance. We invite you to read more about our business, pipeline and citizenship efforts below, and with supplemental content on our website at investor.regeneron.com/2015AR. Our 2015 Annual Report on Form 10-K is available on the Investor Relations portion of our website. MARKETED MEDICINES EYLEA® (aflibercept) Injection and Retinal Disease Programs Market-leading VEGF-Trap approved in more than 100 countries for the treatment of many blindness-causing retinal conditions, including wet age-related macular degeneration and diabetic macular edema (DME). EYLEA net sales in the U.S. increased 54 percent to $2.676 billion for the full year 2015, from $1.736 billion for the full year 2014. Outside of the U.S., where our collaborator Bayer HealthCare commercializes EYLEA, net sales were $1.413 billion in 2015, compared to $1.039 billion in 2014. Regeneron recognized $467 million from its share of net profit outside the U.S. in 2015, compared to $301 million in 2014. This growth was driven in part by the publication in early 2015 of first-year results from an independent National Institutes of Health (NIH)-sponsored comparative effectiveness study in DME. In the study, at one year, EYLEA demonstrated a significantly greater improvement in mean change in best-corrected visual acuity (BCVA) from baseline compared to ranibizumab and bevacizumab, two other VEGF inhibitors used in retinal disease. The rates of most ocular and systemic adverse events were similar across the three study groups. L-1 SHAREHOLDER LET TER

 

standard-of-care in the PALM clinical trial. We are applying the same technologies against the novel coronavirus and hope for similar success.

All of this important research and groundbreaking medicine is built on three decades of investment in ourVelociSuite®technologies. These proprietary end-to-end drug discovery and development tools allow us to quickly identify multiple antibody candidates against diseases – from Ebola to cancer to asthma to rare diseases, such as fibrodysplasia ossificans progressiva. Paired with our excellent clinical development and manufacturing capabilities, the possibilities are truly endless, and we feel that we are just at the beginning of what we can do using the power of science and technology.

Our commitment to continually advancing research through sophisticated and broadly applicable technology propelled our Regeneron Genetics Center®team to the major milestone of sequencing the exomes of over one million people as of February 2020. We are also applying our genetics and biology expertise to explore new modalities that are complementary to our world-class therapeutic antibodies. Key examples include our preclinical work in viral vector and gene therapy technologies, as well as ongoing collaborations with organizations who bring unique expertise in areas like gene silencing, gene editing, and CAR-Ts.

In 2020 and beyond, we will continue to reinvest a significant portion of our growing revenue into our R&D efforts as we believe our scientific innovation and talent are our greatest differentiators. As we look toward the future of Regeneron we have begun to evaluate ex-U.S. commercialization opportunities, starting with exercising our co-commercialization rights for Dupixent in certain countries outside the U.S.

2019 was a busy and successful year for Regeneron, and we believe 2020 will be even more impactful. We will innovate against COVID-19 and the other serious diseases that continue to impact lives, even during a time of pandemic. We have our sights firmly set on the future as we expand the types of ailments we can treat and number of people we can help. The world needs us and the power of science, more than ever.

Sincerely,

In 2016, we initiated a Phase 3 study of EYLEA in diabetic retinopathy in patients without DME, a common degenerative eye disease that impacts people with diabetes. We continue to explore EYLEA in combination with other mechanisms, and have two ongoing clinical programs in this area in collaboration with Bayer HealthCare: aflibercept+PDGFR-beta and aflibercept+ANG2. PRALUENT® (alirocumab) Injection Only monoclonal antibody targeting PCSK9 (proprotein convertase subtilisin/kexin type 9) available in two doses, allowing for tailored therapy based on a patient’s LDL-C lowering needs. In July 2015, PRALUENT was approved by the U.S. Food and Drug Administration (FDA) as adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease who require additional lowering of LDL-C (often referred to as “bad cholesterol”). The effect of PRALUENT on cardiovascular morbidity and mortality has not been determined. Together with our collaborator Sanofi, the U.S. launch is underway. We have focused on physician education about this new class, as well as achieving patient access and reimbursement coverage from health plans. PRALUENT was also approved in the E.U., and launches are underway across the region. The ongoing ODYSSEY OUTCOMES clinical trial program, which is evaluating the potential of PRALUENT to prevent heart attacks, stroke and cardiac death, reached full enrollment in 2015, with more than 18,000 patients at more than 2,000 study centers. Interim results are possible in late 2016, and we expect full results in 2017. L-2

* in collaboration with Sanofi ^ in collaboration with Bayer HealthCare † in collaboration with Mitsubishi Tanabe LATE-STAGE PIPELINE Sarilumab Anti–IL-6 monoclonal antibody under U.S. regulatory review for the treatment of rheumatoid arthritis (RA). In 2015, we reported positive data from three Phase 3 trials of sarilumab in patients with rheumatoid arthritis. Together with our collaborator Sanofi, we submitted the U.S. Biologics License Application in November 2015 and were assigned a Prescription Drug User Fee Act (PDUFA) date of October 30, 2016. In March 2016, the Phase 3 SARIL-RA-MONARCH monotherapy study met its primary endpoint by demonstrating that sarilumab was superior to adalimumab (Humira®) in improving signs and symptoms of active RA at Week 24. The incidence of adverse events, serious adverse events, infections and serious infections was generally similar between groups. Dupilumab First-in-class investigational monoclonal antibody blocking IL-4 and IL-13, two key cytokines believed to be drivers in allergic inflammation, being studied for the treatment of certain allergic conditions, including atopic dermatitis (AD), uncontrolled asthma and eosinophilic esophagitis. Dupilumab was granted a Breakthrough Therapy designation by the FDA for the treatment of adults with moderate-to-severe atopic dermatitis who are not adequately controlled with topical prescription therapy and/or for whom these treatments are not appropriate. We expect to submit an application for FDA approval later this year. In 2016, we reported positive topline results from two large Phase 3 studies in atopic dermatitis and continue to enroll patients in a second pivotal study in asthma. In the atopic dermatitis studies, the overall rate of adverse events was comparable between the dupilumab groups and the placebo groups. REGN2222 Our fully human monoclonal antibody being investigated for the prevention of serious lower respiratory tract infections associated with Respiratory Syncytial Virus (RSV). In 2015, we initiated the Phase 3 NURSERY-Pre-term trial that will evaluate the efficacy, safety, pharmacokinetics and immunogenicity of REGN2222 in infants under the age of six months. Fasinumab Our antibody targeting nerve growth factor being evaluated for potential to offer a novel, non-opioid approach to addressing chronic pain. Two clinical trials of fasinumab for pain due to osteoarthritis and chronic back pain were initiated in 2016. In 2015, we entered into a collaboration with Mitsubishi Tanabe Pharma Corporation to develop and commercialize fasinumab in Japan, Korea, and nine other Asian countries (excluding China). L-4

EARLY-STAGE PIPELINE AND R&D Immuno-oncology Building on our existing antibody collaboration, we launched a new $2.2B global immuno-oncology collaboration with Sanofi. This will provide important new resources to advance our portfolio in this rapidly developing field, which seeks to harness the body’s immune system to fight cancer. We continued to explore multiple approaches in immuno-oncology, including bispecific antibodies, checkpoint inhibitors and antibody drug conjugates. We have two antibodies, a CD20/CD3 bispecific antibody and a PD-1 inhibitor, in clinical studies with data expected in 2016. A number of additional immuno-oncology antibodies are expected to enter the clinic this year and next. Rapid Response & Infectious Disease Regeneron’s Rapid Response capabilities leverage our core VelociSuite® technologies to significantly compress the time required for discovery and preclinical validation of potential treatments for emerging infectious diseases. In 2015, we identified and validated a novel therapeutic cocktail of three antibodies targeting the Ebola virus, and reached an agreement with the Biomedical Advanced Research and Development Authority of the U.S. Department of Health and Human Services to develop, test and manufacture this potential treatment. A Phase 1 study in healthy volunteers is planned for the first half of 2016. We similarly identified and validated an antibody against MERS (Middle East Respiratory Virus) and are working to advance this program, as well as pursuing antibody therapies for other devastating viral diseases such as Zika and Dengue. Regeneron Genetics Center In its second full year, the Regeneron Genetics Center (RGC) continued to grow rapidly in terms of scope, scale and speed. The RGC was created to elucidate, on a large scale, genetic factors that cause or influence a range of human diseases. The team has sequenced approximately 100,000 exomes to date, and is now delivering new target opportunities and validating existing targets in our preclinical and clinical programs. We continued to bring on board world-class collaborators from industry, academia and leading health-systems, and published the RGC’s first peer-reviewed publication in the New England Journal of Medicine. GROWTH In 2015, we grew in many aspects of our business. We continued construction of our world-class 400,000-square-foot manufacturing facility in Raheen, Ireland, which will significantly expand our biologic supply capabilities for commercial products.

PROXY HIGHLIGHTS

WE SEEK YOUR INPUT ON TWO COMPENSATION-RELATED MATTERS

Our mission of long-term commitment to science and innovation has shaped our compensation program, which is designed to sustain our business model and drive our product pipeline. We seek your vote on two compensation-related proposals:

1Approval of the second amendment and restatement of our long-term incentive plan—see “Proposal No. 3: Second Amendment and Restatement of Long-Term Incentive Plan”; and
 
For2A non-binding proposal to approve the compensation of our Named Executive Officers—see “Proposal No. 4: Advisory Vote on Compensation of Named Executive Officers (Say on Pay).”

As discussed under “Compensation-Related Matters—Introduction,” our compensation model has been instrumental in creating a culture of loyal and motivated employees with an entrepreneurial spirit who are dedicated to the Company’s mission to use the power of science to invent medicines for people with serious diseases. As you consider voting on these proposals, please keep in mind the following:

Our equity compensation program supports all of our employees, not just our Named Executive Officers, with approximately 90% of recent annual equity grants awarded to employees other than our Named Executive Officers.
We granted performance-based restricted stock units to our CEO and CSO as a component of their 2019 annual equity awards. This and other carefully calibrated changes to our compensation program were based on investor feedback.
Our 2019 burn rate was at the lowest level in the last seven years due to specific steps we took to manage dilution from equity compensation.
We are asking our shareholders to approve the same number of shares for equity grants that we requested previously and are committed to ensuring that shares available under our long-term incentive plan will be sufficient for at least three years.
Our compensation model underpins our strategy of creating and advancing a high-quality, internally developed product pipeline, which delivered six important medicines and eight additional key indications for these products in the past decade.

2015 Performance Overview (see "Executive Compensation – Compensation Discussion and Analysis – Section 1 – Summary – 2014 Performance Overview" on page 35 for more information)

2015 was another extraordinary year for Regeneron. Our key accomplishments in 2015 included:

47% growth in EYLEA® (aflibercept) Injection global net product sales as compared to 2014;
46% growth in our total revenues as compared to 2014;

19% growth in non-GAAP net income as compared to 2014 (non-GAAP net income is not a measure calculated in accordance with U.S. Generally Accepted Accounting Principles; see Appendix A for a definition of non-GAAP net income and a reconciliation of non-GAAP net income to net income);

advances in our EYLEA® franchise, including regulatory approval of EYLEA® for the treatment of visual impairment due to macular edema secondary to retinal vein occlusion and the treatment of visual impairment secondary to myopic choroidal neovascularization in the European Union; regulatory approval of EYLEA® for the treatment of diabetic retinopathy in patients with diabetic macular edema in the United States; and regulatory approval of EYLEA® for the treatment of retinal vein occlusion in Japan;

regulatory approval and launch of Praluent® (alirocumab) Injection, the first drug approved by the U.S. Food and Drug Administration ("FDA") in a new class of drugs that lower LDL ("bad") cholesterol;

positive Phase 3 data for sarilumab from three Phase 3 studies in patients with rheumatoid arthritis (SARIL-RA-TARGET, SARIL-RA-EASY, and SARIL-RA-ASCERTAIN) and submission of a Biologics License Application for sarilumab with the FDA;

positive pivotal Phase 2b data for dupilumab in asthma and completion of enrollment of the dupilumab atopic dermatitis Phase 3 studies;

new collaboration agreement relating to fasinumab with Mitsubishi Tanabe Pharma Corporation for Japan, Korea, and nine other Asian countries, excluding China;

initiation of Phase 3 clinical study of REGN2222 for Respiratory Syncytial Virus;

continued growth of our clinical development pipeline, as evidenced by the submission of one Investigational New Drug Application with the FDA in 2015 and 13 product candidates (consisting of one Trap-based and 12 fully-human monoclonal antibody product candidates based on the Company'sVelocImmune® technology) in clinical development as of December 31, 2015;

new global strategic collaboration with Sanofi to discover, develop, and commercialize antibody-based cancer treatments in the field of immuno-oncology; and

further important steps to support our current and future growth, including adding two new buildings in the Tarrytown campus providing nearly 300,000 square feet of additional laboratory and office space; significant progress with the construction of a new manufacturing facility in Limerick, Ireland; and increasing headcount on a year-over-year basis by approximately 47% as of December 31, 2015.

Our strong performance is reflected in the appreciation of our stock price, which increased 32%, 217%, and 1554% over the one-, three-, and five-year periods ended December 31, 2015, respectively. This shareholder return places our common stock performance in the 85th, 90th, and 99th percentile, respectively, of all NASDAQ-listed companies with a market capitalization greater than $5 billion in those periods.

Executive Compensation (see "Executive Compensation" on page 35 for more information)

We believe that the leadership of the current executive team has been instrumental to our success in 2015 and prior years, and that an executive compensation program that attracts, motivates, and helps retain key executives, including the Named Officers, is critical to our long-term success.

The main objectives of our executive compensation program are to pay for performance; closely align the interests of shareholders and management; strike a balance between short- and long-term perspectives and support our long-term growth prospects; and attract and retain highly skilled and talented executives in a competitive marketplace.

These objectives were reflected in our 2015 compensation decisions in a number of ways, including the following:

We believe in performance-based compensation and long-term incentives. In 2015, we continued to rely primarily on performance-based compensation, both for our short-term (cash bonus) and long-term incentives (stock option awards). This emphasis on performance-based compensation (particularly long-term incentives in the form of stock options) has been a consistent part of our philosophy since Regeneron's inception, including prior to the significant appreciation in Regeneron's stock price that began in early 2011.

We believe that time-based stock options are inherently performance based, as they provide value to employees only if there is future stock price appreciation and do not provide any value to employees if the stock price declines below the exercise price. As illustrated by the charts in "Executive Compensation – Compensation Discussion and Analysis – Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives," this emphasis on stock options has resulted in close alignment of our Chief Executive Officer's compensation in 2015 and over the last five years with the performance of our common stock over those periods:

    o
    Both in 2015 and over the five-year period ended December 31, 2015, the year-over-year increases in our Chief Executive Officer's compensation were principally attributable to the significant appreciation in our stock price, which increased the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model for valuing stock options.

    o
    Over the same periods, the Black-Scholes grant date fair value of stock option grants to our Chief Executive Officer increased less than the appreciation of our stock price, in part because the absolute number of stock options granted to our Chief Executive Officer decreased in the last three years. The number of shares underlying the annual stock option award to our Chief Executive Officer in 2015 was approximately 39% lower than in 2012, while the stock price appreciated 217% over the same period. As a result, the appreciation in the reported value of our Chief Executive Officer's pay was significantly below the appreciation of our stock price, both cumulatively over the five-year period and on a year-over-year basis. This means that the value of our long-term shareholders' investment in Regeneron grew more rapidly than our CEO's pay over those periods.

    o
    To further illustrate this point, over the last five years, our Chief Executive Officer's total direct compensation, as a percentage of Regeneron's capitalization in the year in which the compensation was awarded, decreased from 0.20% to 0.08%.

Proxy Summary


Table of Contents

      o
      As a result of our emphasis on performance-based compensation, on a relative basis when compared to our Peer Group, the total direct compensation of our Chief Executive Officer over the last three years was also closely aligned with the performance of our common stock even when taking into account the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model.

We believe in year-over-year consistency in making compensation decisions and in striking a balance between the dilutive impact of equity grants and the competitiveness of our compensation program. In our compensation decisions, we focus on the number of shares underlying equity awards relative to the number of basic shares of common stock outstanding, rather than the grant date fair value of the award (as determined according to the Black-Scholes model). We believe this ownership- and dilution-based approach to awarding stock options provides a better measure of the amount of potential increases in shareholder value that would be shared by the awards and allows us to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price.

    o
    As a percentage of the total basic shares outstanding, the 2015 stock option award to our Chief Executive Officer was significantly below the 75th percentile of the companies included in the 2015 Radford Global Life Sciences Survey and only slightly above the 50th percentile (at 0.166% compared to 0.290% and 0.154%, respectively). In addition, this award was below the 50th percentile of our Biotech R&D Peers (which was 0.183%).

    o
    In 2015, the Compensation Committee reduced the number of shares underlying the annual stock option awards to the Named Officers by 15% compared to 2014 (other than

      Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to executives, the Compensation Committee sought to reduce the potential dilutive impact of new equity awards without adversely affecting the competitiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value.

      o
      We continued to pay close attention to our burn rate. Despite the expansive growth of our employee base, which increased by 121% between 2012 and 2015 (from 1,950 full-time employees to 4,303 full-time employees), our burn rate decreased from 5.4% to 4.4% over the same period, and we maintained a three-year burn rate average of 4.1% in 2015. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual stock option awards, without eliminating the broad-based nature of our equity compensation program.

      o
      We believe our approach to equity compensation has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report.

As our President and CEO has observed, “Our dream when we started Regeneron was to build a company where the scientists would be the heroes.” The composition of Regeneron’s board reflects this founding principle: over half of our directors are members of the National Academy of Sciences, and our board members include two Nobel laureates and holders of many scientific awards. In addition, the board includes individuals with experience building shareholder value through all stages of corporate development. Various members bring substantial governance experience gained from service on other boards and others bring financial, policy, and management expertise.

Board Leadership and Role in Risk OversightBOARD LEADERSHIP AND ROLE IN RISK OVERSIGHT

The board of directors recognizes that one of its key responsibilities is to establish and evaluate an appropriate leadership structure for the board so as to provide effective oversight of management. Since 1995, the board has separated the roles of the Chief Executive Officer and the Chairman of the Board, with Dr. Vagelos serving as Chairman and Dr. Schleifer serving as President and Chief Executive Officer. Dr. Vagelos'sVagelos’s extensive leadership experience, his business acumen, and his deep understanding of the healthcare industry have made him an invaluable resource to both the board and Dr. Schleifer.

Compensation of DirectorsCOMPENSATION OF DIRECTORS

Overview

OVERVIEW

The general philosophy we have applied to compensation of our non-employee directors and the Chairman of the Board is similar to the executive compensation philosophy outlined in the Compensation Discussion and Analysis“Compensation-Related Matters” section of this proxy statement. This philosophy, places anincluding its emphasis on equity compensation, inis consistent with the formCompany’s long-term business orientation and has helped ensure alignment of stock options, which reward growth in stock price and align the directors'directors’ interests with those of our shareholders by providing value to the directors only if there is future stock price appreciation and not rendering any value to the directors if the stock price declines below the applicable exercise price. Similar to executive compensation, the emphasis on long-term incentives in the form of stock options has been a consistent part of Regeneron'sRegeneron shareholders.

Non-employee director compensation philosophy and preceded the significant appreciation in Regeneron's stock price that began in early 2011. As discussed in greater detail below, the board of directors voluntarily reduced the number of shares underlying the three most recentmatters are subject to annual stock option awards to the non-employee directors and the Chairman of the Board by 15% each time, consistent with the reductions in annual awards to executive officers implemented in December 2013, 2014, and 2015.

review. The Corporate Governance and Compliance Committee makes recommendations to the board of directors regarding, and the board of directors determines, the compensation of non-employee directors. The Corporate Governance and

Compliance Committee evaluates the appropriate level and form of compensation for non-employee directors at least annually and recommends changes to such compensation to the board of directors when appropriate. Directors who are Company employees receive no additional compensation for serving on our board of directors or its committees. In determining compensation recommendations for the non-employee directors, the Corporate Governance and Compliance Committee considers, among other things, the qualifications, expertise, and demands on our directors, practices of similar companies in the biotechnology industry (including the Peer Group2), and any recommendationscomparative information provided by Frederic W. Cook & Co. In addition, since November 2018, the Corporate Governance and Compliance Committee has required the annual review of non-employee director compensation by an independent compensation consultant, and has engaged Frederic W. Cook & Co. for this purpose in each of the last two years.

The recent changescurrent compensation program for our non-employee directors and the Chairman of the Board (which has been effective for our non-employee directors and the Chairman of the Board since January 2019 and December 2018, respectively, and is further described below) is referred to in this section as the “Current Compensation Program.”3

NON-EMPLOYEE DIRECTOR COMPENSATION PHILOSOPHY

Our philosophy for non-employee director compensation is simple: to attract the most highly qualified directors with a diverse skillset who will serve as stewards of the Company’s long-term prospects and scientific focus. With this in mind, our non-employee director compensation program described below were adopted based on such considerations.

Cash Feesemphasizes equity compensation primarily in the form of stock options, which reward increases in stock price, over cash fees. The board of directors believes that this emphasis is consistent with the Company’s long-term business orientation and Matching Gifthas helped ensure alignment of directors’ interests with those of Regeneron shareholders. Under the Current Compensation Program,

A we have utilized value-denominated equity compensation awards (granted in the form of stock options and a relatively small percentage of RSUs) for our non-employee directors. This feature of the Current Compensation Program is meant to, among other things, ensure greater stability in reported non-employee director receivescompensation on a year-over-year basis. The board of directors believes that the Current Compensation Program is consistent with Regeneron’s philosophy for non-employee director compensation.

CASH FEES AND MATCHING GIFT PROGRAM

In 2019, each non-employee director received an annual retainer of $55,000$90,000 and an annual committee retainer of $10,000 for each standing committee of the Company’s board of directors on which the director serves.served. In 2015, the Chairmanaddition, each chairperson of the Audit Committeeeach standing committee received an additional retainer of $5,000 (increased to $10,000 in the aggregate starting in 2016 as a result of the change described in the following sentence). Starting in 2016, the board of directors approved an annual retainer of $10,000 for each chairperson$10,000. Compared to cash compensation of non-employee directors in our Peer Group, the standing committees of the Company's board of directors, which is in addition to the2019 annual retainer payable to all non-employee directorsfor board service was below the 75th percentile and the annual retainer payable in respect of service as a director on each standingadditional retainers provided to our committee (which remained unchanged). chairpersons were below the median.4

Non-employee directors are reimbursed for their actual expenses incurred in connection with their activities as directors, which included travel, hotel, and food and entertainment expenses. In addition, directors are eligible to participate in the Regeneron Matching Gift Program, which was adopted effective January 1, 2013 and is also available to eligible employees. Under this program, the Company matches contributions made by directors and employees to eligible tax-exempt organizations.

ANNUAL EQUITY AWARDS

2019 and 2020 Equity Awards

The January 1, 2014,2019 and January 2020 annual equity awards to our non-employee directors were made in accordance with the maximum annual match has been increased to $5,000 (from $2,000) per person.

Annual Stock Option Awards

Pursuant toCurrent Compensation Program and complied with the terms ofrespective limits imposed by the Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan and resolutionsthe Settlement. If approved by the shareholders at the 2020 Annual Meeting, such limits will also be incorporated into the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan. See “Proposal No. 3: Second Amendment and Restatement of Long-Term Incentive Plan” for more information on these limits and other terms of this Plan.

With respect to each of the Compensation Committee adopted on December 16, 2014January 2019 and December 16, 2015, eachJanuary 2020 annual equity awards, the board of directors (upon the recommendation of the Corporate Governance and Compliance Committee) determined that the targeted aggregate grant date fair value of such equity awards would be set at $600,000 per non-employee director receivesand consist of stock options with a grant date fair value of $480,000 (or 80% thereof) and RSUs with a grant date fair value of $120,000 (or 20% thereof). The January 2019 annual equity awards to our non-employee directors are shown in the table below. On January 2, 2020, each of the then-serving nine non-employee directors received an automaticequity award comprised of stock options representing 4,361 shares of common stock (with a grant date fair value of $480,281) and 320 RSUs (with a grant date fair value of $119,718). The aggregate grant date fair value of the January 2020 equity awards was $599,999 per non-employee director.

Similar to the process undertaken in respect of the January 2019 annual equity awards, the Corporate Governance and Compliance Committee recommended the approval of, and the board of directors approved, the terms of the January 2020 annual equity awards after consideration of the review, analysis, and recommendations of Frederic W. Cook & Co. Such analysis focused on, among other matters, the market practices of companies in our Peer Group, other relevant industry and market data points, Regeneron’s non-employee director compensation philosophy (including its emphasis on long-term incentives), and the terms of the Settlement.

Terms of Equity Awards

award) equal to one-thirdthe portion of one year that has passed from its date of grant vests on the date of the sharesCompany’s first annual shareholder meeting following the date of grant, and the remaining portion vests on the first anniversary of the date of grant in eachgrant. The RSU awards contain mandatory deferral provisions, according to which the shares underlying the RSUs will generally not be delivered to the non-employee director until the earliest of (i) the termination of the three subsequent calendar years,non-employee director’s service as a member of the board, (ii) the seventh anniversary of the RSU grant date, and (iii) the date of a change in control (as defined in the Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan). A non-employee director may, subject to compliance with applicable tax rules, elect in writing a maximum deferral period longer than the seventh anniversary of the grant date. Other than as discussed below, the vesting of equity awards is generally subject to continued service on the board, and stock option awards generally expire ten years following the date of grant. In 2015, similar to the reductions in annual awards to executive officers and other employees discussed under "Executive Compensation" below, the Compensation Committee reduced the automatic grant of stock options to our non-employee directors by 15%, from 10,838 shares to 9,212 shares of common stock underlying each such stock option. Similar to the rationale for the reductions in annual awards to executive officers and other employees discussed under "Executive Compensation" below, the impetus for the reductions in the automatic grants to the non-employee directors was to reduce the potential dilutive impact of these grants; the reductions also took into account the increase in the Company stock price since the prior years' awards, with the resulting increases in the grant date fair values of the automatic grants (as determined according to the Black-Scholes model for valuing stock options). The reduced grants to our non-employee directors were made on January 4, 2016. This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our non-employee directors, in each case following high stock appreciation, consistent with the reductions in annual awards to executive officers discussed under "Executive Compensation" below.

To the extent they remain unvested and outstanding, stock optionsequity awards granted to a non-employee director continue to vest following the retirement of that director provided applicable conditions relating to the length of the director'sdirector’s service and the director'sdirector’s age have been met. If a non-employee director'sdirector’s service as a member of the board is terminated as a result of his or her death, all of the director's stock optionsdirector’s equity awards will immediately vest in full.

To the extent they remain unvested and outstanding, stock optionsequity awards granted to non-employee directors become fully vested automatically upon a change ofin control of the Company. Each non-employee director has the right to nullify this acceleration of vesting, in whole or in part, if it would cause the director to pay excise taxes under the requirements of the Internal Revenue Code.

Compensation Arrangements of the Chairman of the Board of Directors

COMPENSATION ARRANGEMENTS OF THE CHAIRMAN OF THE BOARD OF DIRECTORS

On December 31, 1998, we entered into an employment agreement with the Chairman of the board of directors, Dr. Vagelos. Dr. Vagelos did not become an officer of the Company or change his title. Pursuant to the terms of his employment agreement, Dr. Vagelos receives an annual salary of $100,000. In$100,000 as a non-officer employee.

Under the employment agreement, we agreed to recommend to theCurrent Compensation Committee that stock option grants be made to Dr. Vagelos for calendar years 2000 through 2003 in the amount of the greater of (a) 125,000 shares or (b) 125% of the highest annual option award granted to an officer of the Company.

In 2011, the Compensation Committee determined that Dr. Vagelos's target grant would be equal to ten times the annual grant for a non-employee member ofProgram, the board of directors setting his target award at 150,000 sharesdetermined that stock options and performance-based restricted stock units (also referred to as “PSUs”) would comprise 70% and 30% of common stock underlying stock options. In December 2013, 2014, and 2015, the Compensation Committee reduced the2019 annual equity award to Dr. Vagelos, by 15% each time,respectively, and set the targeted aggregate grant date fair value of such award at (but no more than) ten times the aggregate grant date fair value of the corresponding annual equity award for our non-employee directors. As in lineprior years, Dr. Vagelos’s 2019 annual equity award reflects, among other things, the key contributions that Dr. Vagelos makes as the Company continues to develop into a fully integrated biotech company with multiple class-leading products, as well as Dr. Vagelos’s crucial role as a trusted advisor to the reductionCEO, other senior managers, and the non-employee directors. It is also designed to incentivize further contributions and ensure Dr. Vagelos’s continued service to the Company in the annual stock option awards to our executive officers and the reduction in the annual stock option awards to the non-employee directors made in January 2014, 2015, and 2016. On December 16, 2015, the Compensation Committee granted Dr. Vagelos stock options to purchase 92,123 shares of common stock, at an exercise price of $555.67 per share, the fair market value per share of our common stock on the date of grant (determined as the average of the high and low sales price per share of common stock on the NASDAQ Global Select Market on the date of grant). future.

The 2019 stock option award granted to Dr. Vagelos vests ratably over four years subject to his continued service and contains change-of-control provisions consistent with those described above for stock optionequity grants to non-employee directors. The 2019 PSU award granted to Dr. Vagelos contains vesting conditions consistent with those described below under “Compensation Discussion and Analysis – Components of Executive Pay: What We Pay and Why We Pay It – Annual Equity Awards.” In addition, if any PSUs held by Dr. Vagelos vest upon a change of control (as a result of performance exceeding the relevant TSR goal for the period from the date of grant to the date of the change of

control), the earned shares will be delivered within 30 days of the vesting determination. Pursuant to the terms of his employment agreement, if Dr. Vagelos dies or is disabled during the term of his employment, all stock options granted to him by the Company will immediately become vested and exercisable.

21 In addition, the award agreements with Dr. Vagelos relating to his 2018 and 2019 stock option awards and 2019 PSU award provide that each such award will continue to vest in accordance with the terms of the applicable award agreement following his qualified retirement (as defined in the applicable Company policy; Dr. Vagelos currently meets the policy requirement).

The Committee also conducts a Form 4 filed by Sanofiperiodic review of environmental, social, and governance (“ESG”) matters. Management, who has the responsibility for formulating and implementing such initiatives and matters, has established for these purposes a Responsibility Committee comprised of cross-functional business leaders.

Our responsibility strategy centers on three focus areas:

Improve the lives of people with serious diseases
Foster a culture of integrity and excellence
Build sustainable communities

In 2019, we set global 2025 responsibility goals, which span across these three focus areas and the environmental and social issues that we believe are most significant to our business and stakeholders. These goals, summarized below, are discussed in detail in our 2019 Responsibility Report.

2025 GLOBAL RESPONSIBILITY GOALS

* See the chart below for our specific environmental targets.

In 2019, we also announced our support of the United Nations Sustainable Development Goals and identified five of such goals where we intend to focus to deliver the most impact: good health and well-being; quality education; gender equality; responsible consumption and production; and partnerships for the goals. Our support of these goals helped guide our selection of the 2025 responsibility goals listed above.

We are proud to have been added to the Dow Jones Sustainability World Index (“DJSI World”) for the first time in 2019, representing one of only four companies from the biotechnology sector recognized. DJSI World is a leading global index comprised of corporate leaders in ESG practices, which recognizes the top 10 percent most sustainable companies in each industry.

In 2019 and 2020 to date, we have also continued to enhance our reporting of the Company’s responsibility efforts and results. For the first time, our 2019 Responsibility Report aligned our disclosures with the SECSustainability Accounting Standards Board (“SASB”) framework. In addition, we are working toward aligning our reporting for the 2020 Responsibility Report with the climate-specific recommendations developed by the Task Force on February 18, 2016. AccordingClimate-related Financial Disclosures (“TCFD”).

Improve the lives of people with serious diseases.As a science-focused company, we operate Regeneron with the long-term outlook required to turn rigorous scientific research into important new medicines. All seven of our approved medicines and the product candidates in our clinical pipeline are homegrown – discovered in Regeneron’s labs using our industry-leading, proprietary technologies. Our support for patients extends beyond the labs to disease education and awareness efforts, product support services, and our commitment to drug access and responsible pricing.

Foster a culture of integrity and excellence.Regeneron’s unique culture makes us who we are. Our culture includes our science-led mindset, our high ethical standards, and our unbridled focus on solving big, complex problems. As we continue to grow, we remain committed to making significant investments to attract and retain top talent and facilitate the diverse and inclusive workforce we require to bring new medicines to people in need. At the end of 2019, 49% of our full-time employees, and 39% of those in leadership positions, were women.

We are equally committed to conducting our business responsibly and ethically. This is demonstrated through the range of policies, practices, and initiatives we have implemented, encompassing areas such as compliance, responsible sales and marketing, ethical clinical trials, responsible supply chain, and product quality and safety.

Build sustainable communities.We believe that our role in creating a healthier world extends beyond creating life-transforming medicines to building a healthy living environment. In 2019, in connection with the selection of our 2025 responsibility goals, we set ambitious medium- and longer-term environmental sustainability targets, as shown below. We plan to begin reporting on our progress toward these goals in the 2020 Responsibility Report.

Certain Relationships and Related Transactions

REVIEW, APPROVAL, OR RATIFICATION OF TRANSACTIONS WITH RELATED PERSONS

 

Review, Approval, or Ratification of Transactions with Related Persons

The board of directors has adopted a written policy for the review, approval, or ratification of related person transactions. The Company considers transactions (or a series of related transactions) in which the Company is a participant, the amount involved exceeds $10,000 in any calendar year, and a director, officer, more than 5% holder of our voting securities, any immediate family member of any of the foregoing, or any related entity of any of the foregoing has a direct or indirect material interest to constitute related person transactions. As amended in January 2015, theThe policy provides for a standing pre-approval of transactions with any passive institutional shareholder who holds more than 5% of our voting securities, transactions where all shareholders receive proportional benefits, and certain transactions with Sanofi. With respect to any new transaction that is deemed pre-approved, the Audit Committee receives a summary of each such transaction and retains the ability to require that one or more of such transactions be subject to the standard approval procedures. The policy also requires that the arrangements relating to a permanent, full-time employment of an immediate family member of a director or executive officer hired by the Company be approved in accordance with the policy. In addition, in the event a person is or becomes a director or executive officer of the Company and an immediate family member of such person is a permanent, full-time employee of the Company, no material, outside-of-the-ordinary-course-of-business change in the terms of employment, including compensation, are permitted to be made without the prior approval of the Audit Committee (except, if the immediate family member is himself or herself an executive officer of the Company, any proposed change in the terms of employment are reviewed and approved in the same manner as compensatory arrangements of other executive officers).

The board of directors has determined that the members of the Audit Committee are best suited to review and approve related person transactions. Accordingly, each related person transaction (other than a transaction that is deemed pre-approved as described above) must be reviewed and approved or ratified by the members of the Audit Committee, other than any member of the Audit Committee that has an interest in the transaction. Under the policy, the Chairman of the Audit Committee is delegated the authority to approve certain related person transactions that require urgent review and approval.

When reviewing, approving, or ratifying a related person transaction, the Audit Committee will consider several factors,

including the benefits to the Company, the impact on a director'sdirector’s independence in the event that a director or his/her immediate family is involved in the transaction, the terms of the transaction, and the terms available to unrelated third parties or to employees in general, if applicable. Related person transactions are approved only if the Audit Committee (or the Chairman of the Audit Committee pursuant to delegated authority in the circumstances noted above) determines that they are in, or are not inconsistent with, the best interests of the Company and our shareholders.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of April 14, 2020, the number of shares of the Company’s Class A stock and common stock beneficially owned by each of the Company’s directors, each of the NEOs referred to below under “Executive Compensation,” all directors and executive officers as a group, and each other person or group of persons known by the Company to beneficially own more than 5% of the outstanding shares of Class A stock or common stock, based upon (unless indicated otherwise) information obtained from such persons, and the percentage that such shares represent of the number of outstanding shares of Class A stock and common stock, respectively.

The Class A stock is convertible on a share-for-share basis into common stock. The Class A stock is entitled to ten votes per share and the common stock is entitled to one vote per share. We have determined beneficial ownership in accordance with the rules of the SEC. Except as otherwise indicated in the footnotes below, we believe, based on the information furnished or otherwise available to us, that the persons named in the table below have sole voting and investment power with respect to all shares of Class A stock and common stock shown as beneficially owned by them, subject to applicable community property laws. We have based our calculation of percentage of shares of a class beneficially owned on 1,848,970 shares of Class A stock and 110,673,311 shares of common stock outstanding as of April 14, 2020, except that for each person listed who beneficially owns Class A stock (and for directors and executive officers as a group), the number of shares of common stock beneficially owned by that person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person assume the conversion on April 14, 2020 of all shares of Class A stock listed as beneficially owned by such person (or persons in the case of directors and executive officers as a group) into common stock and also that no other shares of Class A stock beneficially owned by others are so converted.

In computing the number of shares of common stock beneficially owned by a person (and by directors and executive officers as a group) and the percentage ownership of common stock of such person (and by directors and executive officers as a group), shares of common stock subject to options, PSUs, RSUs, or other convertible securities (if any) held by that person (and by directors and executive officers as a group) that are exercisable or releasable as of April 14, 2020 or are exercisable or releasable within sixty days after April 14, 2020 are deemed to be outstanding. Such shares are not deemed to be outstanding, however, for the purpose of computing the percentage ownership of common stock of any other person.

Executive Compensation

 

2020 COMPENSATION-RELATED PROPOSALS

This year, we ask you to cast your vote on two compensation-related proposals:

IWe seek your authorizationfor a sufficient number of shares to fund our compensation program (Proposal No. 3).1
IIWe seek your inputon our approach to compensation for our “Named Executive Officers”2through the advisory vote commonly referred to as “say on pay” (Proposal No. 4).

To best understand these proposals, it is important to consider our overall approach to compensation and certain key factors that play a significant role in shaping the program’s structure and design. These factors include how closely we tie our pay practices to our mission, strategy, and business model; our ongoing, company-wide pay philosophy; and our process for seeking and carefully considering valuable shareholder feedback each year.

As you decide how to vote on these proposals, please keep in mind the following:

Key Takeaways

1Our equity compensation program supportsall of our employees, not just our NEOs, with approximately 90% of recent annual equity grants awarded to employees other than our NEOs.
2We granted performance-based restricted stock units (“PSUs”) to our CEO and CSO as a component of their 2019 annual equity awards. This and other carefully calibrated changes to our compensation program were based on investor feedback.
3Our 2019 burn rate was at the lowest level in the last seven years due to specific steps we took to manage dilution from equity compensation.
4We are asking our shareholders to approve the same number of shares for equity grants that we requested previously and are committed to ensuring that shares available under our long-term incentive plan will be sufficient for at least three years.
5Our compensation model underpins our strategy of creating and advancing a high-quality, internally developed product pipeline, which delivered six important medicines and eight additional key indications for these products in the past decade.

1In this section, “we,” “us,” and “our” refer to the Company and, where applicable, to the Compensation Committee of the Company’s board of directors.
2Our “Named Executive Officers” or “NEOs” are identified below under “Compensation Discussion and Analysis.”

COMPENSATION-RELATEDMATTERS  /  INTRODUCTION

Our Corporate Culture

Stability, consistency, and an unrelenting focus on science and innovation have been important to our Company’s success and long-term approach. Regeneron’s culture is defined by loyal and motivated employees with an entrepreneurial spirit who are dedicated to the Company’s mission to use the power of science to invent medicines for people with serious diseases. This dedication allowed us to bring six important, internally developed medicines to patients and obtain eight additional key indications for these products in the past decade. We have also consistently outperformed the industry in employee retention in recent years, as demonstrated by our employee attrition rate of less than half the industry average in each of the last five years.3

We continue to be led by Leonard S. Schleifer, M.D., Ph.D., one of the longest-serving founder CEOs in the S&P 500, and George D. Yancopoulos, M.D., Ph.D., our co-founder and Chief Scientific Officer. Drs. Schleifer and Yancopoulos, along with our management and scientific teams, have been the stewards of our long-term approach and are part of the formula for our success. The Company’s dedication to science is also reflected in a board of directors and senior management team that are both heavily populated with top scientific talent.

We firmly believe that our compensation model that emphasizes long-term performance has helped us establish a culture where employees focus on our mission and drug discovery and development. Managing our business for the long term is a core Company belief, as demonstrated by our history of growing through innovation and through a pipeline of internally developed medicines. It also reflects our philosophy of “doing well by doing good,” which encompasses our approach to operating responsibly; making drug-pricing decisions with fairness, affordability, and access at the forefront; and our commitment to patients.

Our Pay Philosophy

Our compensation program supports our core strategy of creating and advancing a high-quality, internally developed product pipeline. The pipeline is directly created by our talented employees, and their engagement, commitment, and achievements are key drivers of pipeline success and therefore our long-term performance.

The primary underpinning of our pay philosophy is to award equity-based pay toall eligible employees to ensure that when we deliver for patients and for shareholders, everyone shares in the upside growth. We award initial equity grants to all new hires, primarily in the form of stock options, in addition to a comprehensive annual equity program. In each of the last five years, approximately 90% of the employee equity grants were awarded to our employees other than our NEOs.4We believe that our broad-based equity program, which emphasizes long-term performance and ensures that all employees can share in our future potential, represents one of our competitive business advantages.

In each of the last five years, approximately90%of employee equity grants were awarded to employees other than our NEOs.


We have primarily used stock options for our employee equity awards because we think stock options are easy to understand, are long-term focused (consistent with the drug discovery and development cycle), and are difficult to manipulate by “managing to metrics.” Importantly, stock options are completely aligned with shareholders’ interests. We also believe that the performance-based nature of stock options is enhanced for companies like Regeneron whose stock price is directly impacted by pipeline developments.

We periodically assess our approach to compensation in light of our business objectives, feedback from our shareholders, and market practices in order to adjust our compensation program based on evolving business needs. As discussed further below, in 2019 we introduced PSUs as a component of the annual equity awards for Regeneron’s

3For example, our 2019 turnover rate was 7.8% compared to an industry average of 18.7%, with turnover in our research & development organization ranking lowest of all employee groups. Industry average is based on the Radford U.S. Life Sciences Trends Report for 2019.

COMPENSATION-RELATEDMATTERS  /  INTRODUCTION

CEO and CSO (as well as the Chairman of the Board). In addition, we introduced restricted stock (“RSAs”) or restricted stock units (“RSUs”) for all other eligible employees as a component of their annual equity awards. While stock options continue to represent a key component of our equity program, we also believe that utilizing a mix of stock options and RSAs/RSUs will provide flexibility for managing dilution and promoting employee retention.

Shareholder Engagement and Feedback

We believe our compensation model is appropriate for our Company and is supported by our long-term performance, but also think it is very important to reach out to our shareholders for ideas, input, and direct feedback. We do this formally through our triennial say-on-pay vote, as well as through direct discussions with our shareholders and informal exchanges in other settings.

Our annual shareholder outreach program is quite extensive – last year we approached shareholders collectively representing nearly 60% of the shares of common stock outstanding as of December 31, 2019 (excluding shares held by our directors and executive officers and Sanofi), which we refer to as “public shareholders”. As part of our outreach, we engaged in direct one-on-one discussions with shareholders representing over 50% of our public shareholders as well as both leading proxy advisory firms. Our Compensation Committee Chair led many of these discussions. The feedback from shareholders has resulted in specific changes to our compensation and corporate governance practices and policies, including the changes discussed below.

Changes that took into account feedback from recent shareholder engagement include the following:

What We HeardWhat We Have Done
Preference for further pay-for-performance alignmentGranted PSUs to CEO and CSO in 2019 with rigorous performance goals tied to theCompany’s absolute total shareholder return (“TSR”) (target = 61% TSR over five years).
Desire for more clarity regardingthe process for determining annualcash incentivesEnhanced the existing process for determining 2019 annual cash incentives and providedmore detailed disclosure about the Compensation Committee’s determination of theCompany performance multiplier in the CD&A section of this proxy statement.*
Support for all-employee equitycompensation strategy, butconcern about resulting burn rate

Maintained our all-employee equity compensation strategy while addressing concernsabout the resulting burn rate using a two-part approach:

Compensation•   Reduce equity award grant guidelines: size of CEO equity awards reduced by almost  60% over the last seven years; and

•   Introduce full-value awards for a portion of the annual equity awards to eligible  employees.

Concern about compensationprogram for non-employeedirectors and the Chairman of theBoard

Introduced a new compensation program for our non-employee directors and the Chairmanof the Board in November 2018. As a result:

•   Reduced by nearly 50% the grant date fair value of equity awards to both the non-employee directors and the Chairman of the Board (granted in January 2019 and  December 2018, respectively); and

•   Introduced full-value awards (RSUs) as part of the non-employee director equity awards.

*See “Compensation Discussion and Analysis – Components of Executive Pay: What We Pay and Why We Pay It – Annual Cash Incentives” for more information.

These are just the latest examples of how our compensation program is continually refined. See the subsection “Compensation Discussion and Analysis – Our Compensation Processes – Shareholder Input and Outreach” for additional information on changes recently adopted based on shareholder feedback.

Our Compensation Program Today: Aligning Pay and Performance

We believe that our compensation program today is effective and aligns with our culture, pay philosophy, and shareholder input and interests.

Significant Performance-Based (“At-risk”) Pay:At-risk pay accounts for a high proportion of compensation for our NEOs and other senior executives, which has been a consistent and defining feature of our program. For our CEO, over 93% of his direct pay5is at-risk and directly correlated to performance; in contrast, the average percentage of CEO at-risk compensation in our Peer Group is significantly lower, at 86%.6

Use of PSUs for CEO and CSO:As discussed above, in 2019 we introduced long-term PSUs to account for 30% of the annual equity awards of our CEO and CSO, which we believe will further incentivize our top executives to drive long-term, sustainable, and exceptional shareholder value creation.

Continual Management of Dilution:Over the last seven years, we have managed dilution from equity compensation by (i) reducing by nearly 60% the number of shares underlying the annual equity awards of our eligible employees, including our CEO; and (ii) adding time-based RSAs/RSUs to the annual long-term incentive mix for our employees (other than those receiving PSUs). Thanks to these measures, 2019 burn rate was at the lowest level in the last seven years. We did this while still maintaining our all-employee equity award strategy and concurrently creating over 6,000 new full-time jobs.7

In the last decade, we sought shareholder approval of additional shares for our long-term incentive plans three times. Each time, we requested the same number of shares – 12 million – and lived up to our commitment not to seek additional shares earlier than three years following approval. Once again, we are asking shareholders to approve 12 million additional shares for equity grants and are committed to ensuring that shares available under our long-term incentive plan will be sufficient for at least three years.

Regeneron Stock Utilization vs. Headcount*

ThisRegeneron’s 2019 burn rate was at the lowest level in the last seven years.


*Burn rate calculated by dividing the number of shares subject to equity awards (stock options, RSAs, and RSUs) granted during the year by the basic weighted-average number of shares of common stock and Class A stock outstanding during the year. PSUs are to be reflected in the burn rate calculation for the year in which they are earned and, therefore, do not impact the burn rate shown in the chart. Headcount numbers based on the number of employees as of December 31 of the applicable year.

Alignment of Pay with Performance:As stock options comprise most of our CEO’s reported compensation and do not provide value unless there is positive shareholder return, such compensation is closely aligned with the Company’s performance. The charts below illustrate this alignment based on both (i) the as-reported grant date fair value and (ii) a realizable pay metric.

5We define “direct pay” or “direct compensation” as total compensation as reported in the Summary Compensation Table in the applicable proxy statement, other than the amounts reported as “All other compensation” and (if applicable) amounts reported under “Change in pension value and nonqualified deferred compensation earnings.”
6Based on the Peer Group median for each compensation component (using data reported for 2018). See the subsection “Compensation Discussion and Analysis – Our Compensation Processes — Peer Data” below for a list of the companies included in our Peer Group.
7In 2019, we added 730 new jobs and yet reduced the burn rate for that year by 1.1%, from 4.7% to 3.6%.

COMPENSATION-RELATEDMATTERS  /  INTRODUCTION

1Alignment Based on Grant Date Fair Value.Over the last five years, our CEO’s total direct compensation tracked our TSR, as shown below.

CEO Total Direct Compensation vs. Indexed TSR*
($ millions)

 

*“Total direct compensation” or “TDC” means total compensation as reported in the Summary Compensation Table in the applicable proxy statement (other than amounts reported as “All other compensation”). “Indexed TSR” in the period presented in this chart is expressed as a percentage of the closing price of our common stock on 12/31/2015.

2Alignment Based on Realizable Pay.Our CEO’s realized/realizable pay from compensation awarded over the last five years was significantly lower than the values reported for that compensation ($20.3 million of realized/realizable pay versus $148.0 million of reported value). Nearly all of the realized/realizable value was from salary and bonus because there was almost no value provided from equity awards granted during this five-year period. The chart below compares the aggregate, as-reported value of our CEO’s total direct compensation over the last five years with his realized/realizable pay during the same period. We believe this demonstrates that our CEO compensation design rewards performance and, conversely, limits payouts in respect of periods with flat or negative TSR (as was the case in the period depicted below).

Five-Year CEO Total Direct Compensation – Reported vs. Realized/Realizable*
($ millions)

*“Realized/realizable pay” means, for any measurement period, the sum of the (i) as-reported base salaries and annual cash incentives paid during such period, (ii) amounts realized as a result of the exercise of stock options awarded during such period, and (iii) amounts that could have been realized as a result of the exercise of outstanding and “in-the-money” stock options or the sale of shares delivered upon vesting of other equity awards, in each case awarded during such period (using the closing price of our common stock on the last trading day of the period).

COMPENSATION DISCUSSION AND ANALYSIS

The following Compensation Discussion and Analysis provides(“CD&A”) describes the philosophy, objectives, and structure of our fiscal year 2019 executive compensation program. This CD&A is intended to be read in conjunction with the subsequent tables presented under “Compensation Dashboard – 2019 Executive Compensation Tables,” which provide further historical compensation information aboutfor our 2015“Named Executive Officers” or “NEOs”.8

EXECUTIVE SUMMARY

Our compensation program underpins our strategy of delivering sustainable, long-term growth through continued innovation. We believe the success of our compensation program and our performance (both financial and operational, in particular with respect to our pipeline progress) are best judged from a long-term perspective. The past decade was a transformational period for Regeneron – the following executive officers (the "Named Officers"), whose compensation is set forthCompany evolved from a small biotech with a mostly pre-commercial portfolio to a large-cap company with seven commercialized products, including two with global annual net product sales of over $2 billion; a pipeline with multiple promising product candidates (including a comprehensive immuno-oncology program); a deep bench of scientific and industry talent; proprietary platform technologies that help accelerate and improve the traditional drug development process; one of the largest genetics sequencing efforts in the Summary Compensation Table

world; and a strong balance sheet with capital to advance and expand our wholly-owned R&D pipeline. We are proud that in that period we brought six important, internally developed medicines to patients and obtained eight additional key indications for these products. In the other compensation tables included in this proxy statement:most recent period, we made further progress and celebrated significant scientific, operational, and financial accomplishments, as discussed further under “2019 Business Highlights” below.

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

To keep key managers motivated and focused, we believe that we must continue to provide an executive compensation package that prioritizes achievement of our long-term goals (particularly those related to drug discovery and development), incentivizes high performance, and strongly aligns with the direct interests of our long-term investors.

Compensation decisions of the past year balance consistency and flexibility following a thoughtful process for setting CEO and other NEO compensation. We believe the resulting pay outcomes were commensurate with 2019 performance and the NEOs’ contributions in 2019 and will incentivize performance in the years to come.

2019 COMPENSATION HIGHLIGHTS

Select compensation highlights from the past year include the following:

Base Salaries

There were minimal changes to the base salaries of our NEOs paid in 2019, with base salary increases reflecting a 3.5% merit increase (consistent with those for other employees) and, in the case of Mr. Landry and Dr. Murphy, base salary adjustments of $26,200 and $64,400, respectively, to reflect promotions.

Annual Cash Incentives

(New)In response to shareholder input, we enhanced the existing process by which the Compensation Committee determines the annual cash incentive Company performance multiplier and provided additional disclosure about the Committee’s decision-making (see “Components of Executive Pay: What We Pay and Why We Pay It – Annual Cash Incentives” below for additional information).
Neil Stahl, Ph.D.
Following a year with a great deal of clinical and operational success, the annual cash incentives paid out at 177% of each NEO’s target bonus, on average, in 2019.

Annual Equity Awards

(New)In December 2019, following feedback from shareholders and in light of other relevant considerations, we granted PSUs as part of the 2019 annual equity award to our CEO and CSO (as well as the Chairman of the Board). The PSUs are long-term awards intended to motivate exceptional shareholder value creation over the next five years. The PSUs accounted for approximately 30% of each officer’s 2019 annual equity awards, while the remaining 70% consisted of stock options. Key features of the PSUs, which are discussed more fully below under “Components of Executive Pay: What We Pay and Why We Pay It — Annual Equity Awards” below, include:
Long-term, five-year performance period (with an opportunity for accelerated payout after four years if performance is strong); and
Rigorous performance goals tied to the Company’s TSR over the performance period (target is a 61% TSR over five years and minimum threshold payout requires at least a 28% TSR).

2019 BUSINESS HIGHLIGHTS

Our corporate performance for 2019 was assessed in three categories: (1) factors related to our product pipeline and development for both the near- and long-term; (2) factors regarding our financial performance and operations; and (3) factors related to our talent, culture, and corporate responsibility.

As in prior years, the factors analyzed under category (1) continued to be a key measure for the Compensation Committee’s assessment and calculating the Company performance multiplier. This recognizes the importance of science and innovation as well as the critical role of the development pipeline in the Company’s long-term success.

We provide a comprehensive overview of our 2019 achievements and the Compensation Committee’s assessment of those achievements in the subsection “Components of Executive Pay: What We Pay and Why We Pay It — Annual Cash Incentives.”

Compensation Objectives and ElementsHOW OUR PAY PROGRAM WORKS

We believe that the leadership of the current executive team has been instrumental to our success in 2015 and prior years, and that an executive compensation program that attracts, motivates, and helps retain key executives, including the Named Officers, is critical to our long-term success.

Our executive compensation program is designed to achieve four main objectives:

pay for performance;

closely align the interests of shareholders and management;
strike a balance between short- and long-term perspectives and support our long-term growth prospects;business model and

attract drive our product pipeline. We operate in an industry with fierce competition for talent, and believe an attractive compensation program is necessary to incentivize, motivate, and retain highly skilled and talented executives in a competitive marketplace.

To realize these objectives, we utilize five primary compensation elements, which are summarized in the table below and discussed in detail under "Section 4 – Elements of Executive Compensation":

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

OUR COMPENSATION PHILOSOPHY AND OBJECTIVES

We consider the following objectives inwhen determining the 2015 compensation of our executives, including the Named Officers, as discussed in greater detail for each of these objectives under "Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives." In particular:

We believe in performance-based compensationNEOs and long-term incentives.    In 2015, we continued to rely primarily on performance-based compensation, both for our short-term (cash bonus) and long-term incentives (stock option awards). This emphasis on performance-based compensation (particularly long-term incentives in the form of stock options) has been a consistent part of our philosophy since Regeneron's inception, including prior to the significant appreciation in Regeneron's stock price that began in early 2011.

other executives:

2Providing at-risk, performance-based pay to all employees, with increased performance accountability as responsibility increases 5Aligning our executive compensation with shareholder interests by linking compensation to the core elements of our long-term performance
     
3Prioritizing design simplicity, long-term orientation, and avoiding too much emphasis on short-term metrics 6Using independent sources of expertise and comparative data to inform our decision-making
    
  7Assessing our compensation objectives in light of measurable results
1Driving innovation through our ownership culture while managing the dilutive impact of equity grants

We believe that time-based stock options are inherently performance based, as they provide value to employees only if there is future stock price appreciation and do not provide any value to employees if the stock price declines below the exercise price.    As illustrated by the charts in "Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives," this emphasis on stock options has resulted in close alignment of our Chief Executive Officer's compensation in 2015 and over the last five years with the performance of our common stock over those periods:

    o
    Both in 2015 and over the five-year period ended December 31, 2015, the year-over-year increases in our Chief Executive Officer's compensation were principally attributable to the significant appreciation in our stock price, which increased the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model for valuing stock options.

    o
    Over the same periods, the Black-Scholes grant date fair value of stock option grants to our Chief Executive Officer increased less than the appreciation of our stock price, in part because the absolute number of stock options granted to our Chief Executive Officer decreased in the last three years. The number of shares underlying the annual stock option award to our Chief Executive Officer in 2015 was approximately 39% lower than in 2012, while the stock price appreciated 217% over the same period. As a result, the appreciation in the reported value of our Chief Executive Officer's pay was significantly below the appreciation of our stock price, both cumulatively over the five-year period and on a year-over-year basis. This means that the value of our long-term shareholders' investment in Regeneron grew more rapidly than our CEO's pay over those periods.
      o
      To further illustrate this point, over the last five years, our Chief Executive Officer's total direct compensation, as a percentage of Regeneron's capitalization in the year in which the compensation was awarded, decreased from 0.20% to 0.08%.

      o
      As a result of our emphasis on performance-based compensation, on a relative basis when compared to our Peer Group, the total direct compensation of our Chief Executive Officer over the last three years was also closely aligned with the performance of our common stock even when taking into account the reported grant date fair value of our Chief Executive Officer's stock option awards as determined according to the Black-Scholes model.

We believe in year-over-year consistency in making compensation decisions and in striking a balance between the dilutive impact of equity grants and the competitiveness of our compensation program.    In our compensation decisions, we focus on the number of shares underlying equity awards relative to the numberas a percentage of basic shares of commoncapital stock outstanding rather than the grant date fair value of the award (as determined according to the Black-Scholes model).when making decisions on equity-based pay for our NEOs. We believe this ownership- and dilution-based approach to awarding stock options provides a better measure of the amount of potential increases in shareholder value that would be shared by the awards and allows us to evaluate suchstock option and other equity grants on a consistent basis as comparedyear-over-year, without regard to other companies and regardless of fluctuations in the share price, and is aligned more closely with shareholder interests. We also believe this approach allows for a more meaningful comparison to industry peers.

The 2019 CEO equity grant as a percentage of Regeneron's or other companies' common stock. Further, focusingbasic shares outstanding was below the 75th percentile of the market composite data prepared by Radford from the 2019 Radford Global Life Sciences Survey (U.S. public biotechnology and pharmaceutical companies with between 1,500 and 20,000 employees) and our Peer Group data (we refer to the composite data below as the “Market Composite Data”).10

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

Focusing on the number of shares, and the incremental sharing rate of potential future upside (ratherrather than targeting a specific Black-Scholes grant date fair value)value, avoids rewarding officersexecutives with larger grant sizes following a decline in stock price. In line with this approach, when our stock price.

    o
    As a percentageprice declined or remained relatively flat in each of 2016, 2017, 2018, and 2019 compared to the total basic shares outstanding,prior year, we continued to reduce the 2015number of stock option awardoptions awarded to our Chief Executive Officer was significantly below the 75th percentile of the companies included in the 2015 Radford Global Life Sciences Survey and only slightly above the 50th percentile (at 0.166% compared to 0.290% and 0.154%, respectively).CEO. In addition, this award was below the 50th percentile of our Biotech R&D Peers (which was 0.183%).

    o
    In 2015, the Compensation Committee reduced2019, the number of shares underlying the annual stock option awardsour CEO’s award was reduced by 10%, which contributed to the Named Officers by 15% compared to 2014 (other than Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decreasea 22% reduction in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to executives, the Compensation Committee sought to reduce the

        potential dilutive impact of new equity awards without adversely affecting the competitiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value.

      o
      We continued to pay close attention to our burn rate. Despite the expansive growth of our employee base, which increased by 121% between 2012 and 2015 (from 1,950 full-time employees to 4,303 full-time employees), our burn rate decreased from 5.4% to 4.4% over the same period, and we maintained a three-year burn rate average of 4.1% in 2015. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual stock option awards, without eliminating the broad-based nature of our equity compensation program.
      o
      We believe our approach to equity compensation has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report.

Highlights of Compensation Policies and Practices

Risk ManagementOur Compensation Committee regularly reviews our compensation strategy and practices, including an annual review of our compensation-related risk profile, to ensure that our compensation-related risks are not reasonably likely to have a material adverse effect on the Company.

Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives

Pay for Performance

We believe in rewarding performance and establishing a strong link between compensation and both individual and corporate performance at all levels of the Company. We also believe that accountability and total compensation potential should generally increase with position and responsibility and that the proportion of the performance-based component of compensation should increase with position and responsibility. Consistent with this view, individuals with greater responsibility and ability to influence our achievement of corporate goals and strategic initiatives generally are targeted with higher levels of cash compensation, but have a higher proportion of their total cash compensation represented by cash bonus, the amount of which is based on individual and/or corporate performance and is, therefore, at risk. Similarly, equity-based compensation is higher for persons with higher levels of responsibility, making a significant portion of their total compensation dependent on long-term stock appreciation and, therefore, long-term corporate performance.

This pay-for-performance philosophy was strongly reflected in the mix of compensation elements, or "pay mix," of our Named Officers in 2015. The following charts display the mix of 2015 compensation (fixed vs. performance-based and long-term vs. short-term) of our Chief Executive Officer and our other Named Officers (excluding our Chief Executive Officer) and the mix of compensation elements of the companies included in the 2015 Radford Global Life Sciences Survey. As shown in these charts, 97% and 96% of the total direct 2015 compensation of our Chief Executive Officer and our other Named Officers, respectively, consisted of performance-based compensation, which exceeds the average percentage of performance-based compensation paid by the companies included in the 2015 Radford Global Life Sciences Survey by 7% and 14%, respectively. Accordingly, based on these metrics, our 2015 executive compensation program was more heavily weighted toward "at risk," performance-based components.

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

The “at-risk” design of our CEO’s compensation package is also demonstrated by the history of limited payouts in respect of periods with flat or negative TSR. See “Compensation-Related Matters – Introduction – Our Compensation Program Today: Aligning Pay and Performance” above for a comparison of our CEO’s reported versus realized/ realizable pay over the Compensation Committee manageslast five years.

3Prioritizing design simplicity, long-term orientation, and avoiding too much emphasis on short-term metrics

We primarily rely on stock option grants for our NEOs’ equity-based pay because they are simple, do not deliver realizable compensation if shareholders fail to benefit from a stock price increase, are in sync with the pay mix such that a substantial portiontime required for discovery, development, and commercialization of pay is dedicatednovel therapies, and would be difficult to "at risk," performance-based compensation, with that portion to comprise a significantly greater percentage of total direct compensation“game,” unlike some pre-set short-term performance goals. In addition, in 2019 we introduced for our CEO and CSO (as well as compared to the averageChairman of the

companies included Board) PSUs with a long-term, five-year performance period (with an opportunity for an accelerated payout after four years if performance is strong) and straightforward TSR goals provided in the 2015 Radford Global Sciences Survey. The Compensation Committee believes that this mix of pay best aligns the interests of our Named Officers with those of our shareholders over time.

Shareholder Alignment

We believe that our long-term performance and our robust pipeline are evidence of providing our NEOs and other employees with the right incentives. Tying compensation realized byto long-term, Company-wide success has enabled us to encourage decision-making that we believe is consistent with the long-term sustainability of our leadership team,Company and our reputation. The types of equity awards we have utilized support our strategy of driving value creation through innovation, our pipeline, and demand for our products.

4Balancing year-over-year consistency and flexibility in making compensation decisions

The design and operation of our compensation plans (including our reliance on equity awards as a primary long-term employee incentive) for our NEOs have been consistent since the Company’s inception. Our decision-making process for setting NEO compensation, including the Named Officers, should show a strong relation to the value realized by our shareholders. This principle is reflected boththeir annual salaries, year-end cash incentives, and equity awards, has been similarly consistent in the pay mix referenced above and in our focus on stock options, as the value realizedrecent years. However, when warranted by the holdercircumstances, we adapt and make adjustments. Based on shareholder feedback and other relevant considerations, in 2019 we introduced PSUs as a component of the annual equity awards for our CEO and CSO and RSAs as a component of the annual equity awards for our other NEOs. See the subsection “Our Compensation Processes” below for further information regarding our compensation decision-making.

5Aligning our executive compensation with shareholder interests by linking compensation to the core elements of our long-term performance

Our NEOs’ direct pay, except for base salary, depends on performance. We do this to align these senior executives’ at-risk pay with their levels of authority and with shareholders’ interests. In addition, our NEOs receive no value from their stock option or PSU awards if shareholders do not benefit, which results in a complete alignment of such compensation with shareholder interests. No amount of time will make a stock option ifdeliver any is dependent upon, and directly proportionate to, appreciation invalue unless the company’s stock price of our common stock. Since our inception, we have consistently structured our executive compensation based on our belief thatincreases. In addition, stock options naturally align executivesreward our NEOs for increasing shareholder value over the entire 10-year option term, which we believe is consistent with the creation of future shareholder value.drug discovery and development cycle. Similarly, any PSU vesting is determined over a long-term, five-year performance period (with an opportunity for an accelerated payout after four years if performance is strong). We also believe that the performance-based nature of equity awards such as stock options haveand PSUs is enhanced for companies like Regeneron whose stock price is directly impacted by pipeline developments. We further link our NEOs’ and other executives’ pay to their decisions that affect our performance by incorporating an assessment of the caliber of our drug-development pipeline into our compensation decisions.

6Using independent sources of expertise and comparative data to inform our decision-making

The Compensation Committee retains its independent compensation consultant, Frederic W. Cook & Co., to perform projects at its direction and to provide professional expertise. We also use data compiled by management’s consultant, Radford. Comparative compensation data are used to review each component of our NEOs’ compensation against the Peer Group as well as their total annual compensation in relation to the Peer Group, while taking into account various factors such as the executive’s performance, past compensation history, experience, and the role in the Company’s success. We also look at survey data for companies in our area, in our industry, and in our size range to inform our compensation deliberations.

We use Peer Group data as a point of reference, but Peer Group data do not represent the only factor considered and we do not peg compensation to a specific percentile of our Peer Group. We also consider the practices of our “Biotech R&D Peers”—the 10-company sub-group of peers viewed as having businesses and drug discovery and development cultures that are most similar to Regeneron’s, with similarly-sized employee bases. See the subsection “Our Compensation Processes—Peer Data” below for additional information.

The Compensation Committee’s consultant does not perform any other services for the Company (other than those provided to the Corporate Governance and Compliance Committee with respect to non-employee director compensation matters, as discussed under “Board of Directors—Compensation of Directors” above) and has been fundamentaldetermined by the Committee to be independent.

7Assessing our compensation objectives in light of measurable results

As a science-focused company, we believe in assessing our compensation philosophy and objectives, as they relate to our ability to attract, motivate,NEOs and retain top talent whose contributionsother employees, in light of measurable results. Those include our pipeline productivity and leadership have driven the Company's achievementsustaining an engaging employee culture that drives innovation, which we assess based on relevant metrics. For example, we review our attrition rate (which in each of corporate and strategic goals and resulted in a substantial enhancement of shareholder value. Over the one-, three-, and five-year periods ended December 31, 2015, our stock price increased 32%, 217%, and 1554%, respectively. This shareholder return places our common stock performance in the 85th, 90th, and 99th percentile,

respectively, of all NASDAQ-listed companies with a market capitalization greater than $5 billion in those periods. Our use of stock options ensures alignment of the interests of our executives, including the Named Officers, with those of Company shareholders, as our executives not only benefit from our successes, and the resulting appreciation of our stock, but are also impacted by decreases in our stock price.

The following chart compares our TSR over the last five years withwas at less than half the compensation of our Chief Executive Officer over the same period. We do not focus primarily on total direct compensation as a key metric, as it is derived in part from the reported grant date fair value of stock option awards as determined according to the Black-Scholes model. As further discussed below, in assessing stock option awards, we primarily considerindustry average) and the number of shares underlying the awards relative to the number of basic shares of common stock outstanding in order to evaluate such awards on a consistent basis as compared to other companiesregulatory approvals for our products (approvals for six products and regardless of fluctuations in the price of Regeneron's or other companies' common stock.

As shown in the table above, compensation awarded to our Chief Executive Officer over the last five years closely tracked our TSR over the same period, and percentage increases in such compensation were considerably smaller than our TSR over the same period (533% increase in total direct compensation compared to 1554% TSR). The overwhelming portion of the increase in our Chief Executive Officer's total direct compensation over this period is directly attributable to the value of the non-cash components of his compensation package, primarily stock option awards valued according to the

Black-Scholes model. Consistent with our objective to align the interests of our executives with the interests of our shareholders, as the price of our common stock appreciated over the last five years, the value of stock option awards, the most significant component of the compensation of our Chief Executive Officer (as well as the other Named Officers), increased as well.

In addition, on a year-over-year basis, percentage increases in our Chief Executive Officer's total direct compensationeight additional key indications in the last five years were significantly below the year-over-year appreciation of10 years). We periodically review our stock price, as shown in the chart below.

Balance between Short- and Long-Term Perspectives

The Company's compensation program has been designed to strike a balance between short- and long-term compensation in light of the Company's available resources; its growth trajectory; its goal of offering compensation packages that are competitive with those of companies in the Peer Group and the broader biopharmaceutical industry; and its objective to

retain and motivate high-performing employees and closely align their interests with the interests of shareholders. We utilize base salary and annual cash bonuses to compensate our executives over the short term by providing a base level of income and rewarding performance on an annual basis, and we utilize stock options to foster a long-term perspective and reward long-term performance.

Why stock options?





Time-based stock options represent the foundationBalance immediate focus withpursuit of our compensation philosophy and an integral part of our executive compensation program. Since our inception, we have consistently structured our executive compensation based on our belief that stock options naturally align executives with the creation of future shareholder value and are the best vehicle to retain and foster the entrepreneurial aspects of our culture. The core group of our senior management (Drs. Schleifer, Yancopoulos, and Stahl) has been with Regeneron for over 20 years and has been instrumental in driving shareholder value over this period. We discussed our use of time-based stock options as a critical component of our compensation program as part of our 2015 shareholder outreach (discussed in greater detail below) and were again encouraged by the fact that a number of our key shareholders were supportive of time-based stock options and viewed them as an excellent compensation tool for a high-performing, growth-oriented company.

In 2015, as in other recent years, we relied on time-based stock options as the primary vehicle for offering long-term incentives to our employees, including the Named Officers, and for linking compensation and performance. However, we reduced the number of shares underlying the annual stock option awards to the Named Officers by 15% compared to 2014 (other than Mr. Terifay's award, which remained at the 2014 level due to his promotion to Executive Vice President, Commercial). This reduction constituted the third consecutive double-digit percentage decrease in such annual grant.

We believe that time-based stock options are inherently performance-based, offer an excellent compensation mechanism for getting our management team to act in ways that ensure the long-term success of Regeneron, and are appropriate and advantageous for the following additional reasons:

The executive only realizes value from stock options if the price of the Company's common stock increases and the executive continues to serve through the vesting period. The value is solely tied to an increase in the Company's stock price, aligning the interests of executives with those of shareholders.


The executive has the opportunity to realize value if the price of the Company's common stock continues to increase over the remainder of the ten-year term of the option. Time-based options, therefore, promote the long view and motivate and reward the executive for Company performance not only over the four-year vesting term, but also the ten-year option term.

Compared to full-value awards, stock options provide for greater leverage and, therefore, alignment of employee incentives with those of our shareholders. They also amplify downside risk, as they do not provide any value to the holder if the stock price declines below the exercise price (determined as of the date of grant).

Stock options have played an important role in our success and have helped us to conserve the Company's cash.

Stock options are highly valued by employees, particularly in our industry. They have helped us attract and retain entrepreneurial employees and foster an ownership culture, which we believe has been part of the Company's formula for success.

Time-based stock options are understood by employees and are straightforward to administer. We also believe that they are less likely to cause employees to pursue attainment of a particular performance metric at the expense of value creation for our shareholders generally.

Stock options generally qualify as performance-based compensation for purposes of the deduction limit of Section 162(m) of the Internal Revenue Code, and all amounts realized by our Named Officers upon exercise of their stock options are expected to be fully deductible by us.

We consider factors including the executive’s scope of responsibilities, experience, and annual performance when setting base salaries. We also consider base salaries of comparable positions in the charts under "– Payregion, among our peers, and in the broader biopharmaceutical industry. Finally, while there is no target benchmark level for Performance" above, 91%salaries, we generally position total target cash compensation (consisting of base salary and annual cash incentives) at or below the market median based on relevant comparative data.

ANNUAL CASH INCENTIVES

Our NEOs are eligible for cash incentives based on annual performance. We use these annual incentive opportunities to reward short-term achievements and milestones towards our long-term goals.

We focus on our overall corporate performance to determine the cash incentives of our CEO and our CSO. Our other NEOs’ cash incentives are assessed on both our overall corporate performance and on their individual contributions. For 2019, annual cash incentive opportunities for each NEO were weighted as shown below:

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

Corporate Performance

Feedback from our shareholder engagement efforts since our last annual meeting suggested that the annual cash incentive goals appeared subjective, and investors expressed a desire for more concrete, objective, and transparent goals so that they could more fully understand how cash incentive payments were linked to corporate and individual performance. Our Compensation Committee listened to this feedback and enhanced the existing process for determining the cash incentive for 2019. The enhanced approach also incorporates greater involvement of all non-employee directors and the Chairman of the total direct compensationBoard in reviewing the Company’s performance for purposes of setting the annual cash incentive.

Corporate performance for 2019 was assessed in three categories: (1) factors related to our product pipeline and development for both the near- and long-term; (2) factors regarding our financial performance and operations; and (3) factors related to our talent, culture, and corporate responsibility. As in prior years, the factors analyzed under category (1) continued to be a key measure for the Compensation Committee’s assessment and calculating the Company performance multiplier. This recognizes the importance of innovation as a key component of the Company’s business strategy and valuation, as well as the critical role of the development pipeline in the Company’s long-term success.

For each of the factors listed in the table above, the Compensation Committee assessed actual performance for the year. Based on a holistic assessment of these factors, the Compensation Committee set the Company performance multiplier at 1.85, from a possible range of 0 to 2.0.

Individual Performance

The personal performance multiplier may range from 0 to 1.5. For the explanation of individual factors considered in the cash incentive decisions, see the subsection “Compensation Dashboard—Additional Compensation Information—Annual Cash Incentives.”

2019 Earned Cash Incentives

In determining the level of 2019 cash incentives earned, we calculated the NEOs’ respective target cash incentive amounts (which, for our CEO, was set approximately at the median of the Peer Group) and applied the Company performance multiplier based on the Company’s achievement of 2019 objectives; and, for the three NEOs who also have a personal performance component, we applied a personal performance multiplier. For the three NEOs with a personal performance component, the personal performance component had a 40% weighting and the Company performance component had a 60% weighting.

Based on the achievement of corporate goals (discussed above) and individual goals (discussed in the subsection “Compensation Dashboard—Additional Compensation Information—Annual Cash Incentives”) in the past year, our NEOs earned the followed cash incentives in 2019:

ANNUAL EQUITY AWARDS

The majority of our Chief Executive OfficerNEOs’ pay is designed to reward delivery of sustainable long-term value creation, which we believe is created by focusing on the discovery, development, and commercialization of new medicines. Our equity compensation program is intended to reward this long-term performance simply, using primarily stock options and, in the case of our CEO and CSO, also PSUs and giving effect to the following considerations:

 

Performance-Based Equity
Our NEOs’ stock option grants, which in 2019 comprised 70% of each NEO’s annual equityawards, are performance-based because we determine the award size after taking intoaccount corporate and/or individual performance assessments, and then the award onlydelivers value if we deliver stock price appreciation for shareholders after grant.
In addition, our CEO’s and CSO’s PSU grants, which in 2019 comprised the other 30% of eachsuch executive’s annual equity award, are performance-based because we determine theaward size after taking into account corporate performance assessments, and then the awardonly vests if the performance criteria are satisfied (minimum threshold payout requires at leasta 28% TSR over five years).
Long-Term Value Creation
Our NEOs’ and other employees’ stock option grants have ten-year terms and four-yearvesting provisions (generally requiring our employees, including our NEOs, to remainemployed for four years in order for all options to vest*) to align with long-term value creationand the development cycle of our products.
Our NEOs’ and other employees’ RSAs/RSUs also promote long-term employment: RSAsawarded as a component of annual equity awards vest 50% on the second anniversary of thedate of grant and 50% on fourth anniversary of the date of grant, which is a more backloadedvesting schedule than is typical in the industry.
Our CEO’s and CSO’s PSU grants incorporate a long-term, five-year performance period (withan opportunity for an accelerated payout after four years if performance is strong).
Meaningful Holding Requirements
We require NEOs to retain a significant amount of equity within five years of their employmentwith Regeneron:
Our CEO and CSO must own shares with a value at least 6-times their respective base salaries.
Our other NEOs must own shares with a value at least 2-times their respective base salaries.
Risk Mitigating Design Features
We have a recoupment (clawback) policy that enables us to reduce or recoup equity and otherincentive compensation for compliance violations by NEOs and other covered officers andemployees; importantly, the policy covers both financial and non-financial violations.
We prohibit our NEOs from hedging or pledging Regeneron securities they hold, includingthose acquired through employee equity awards.
*In the case of our CEO, this is subject to the terms of his employment agreement. See the subsection “Compensation Dashboard—2019 Compensation Tables—Post-Employment Compensation—Leonard S. Schleifer, M.D., Ph.D. Employment Agreement.” In the case of our CSO, any unvested stock options granted to him in December 2019 will continue to vest following his qualified retirement (as defined in the applicable Company policy).


As outlined in the chart below, our Compensation Committee utilizes a customized framework for determining the size of the annual equity awards of our NEOs and other executives. The Compensation Committee’s primary consideration is the number of shares underlying the equity awards as a percentage of basic shares of capital stock outstanding, which is evaluated on an options-equivalent basis to allow for a meaningful year-over-year comparison.

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

PRIMARY CONSIDERATIONTargeted Percentage of Total Basic Shares Outstanding
Our evaluation of the awards as a percentage of the total basic shares outstanding comparedto our Peer Group and the Market Composite Data. This enables us to evaluate grants on aconsistent basis regardless of stock price fluctuations of our or our reference companies’stock prices. Focusing on the number of shares also avoids an outcome where NEOs areprovided larger grants following stock price declines or penalizing high performance withsmaller grants. For our CEO, we generally target between the 50th and 75th percentiles of theMarket Composite Data.
SECONDARY CONSIDERATIONSCorporate Performance Assessment
Our assessment of Regeneron’s corporate accomplishments for 2019, particularly as theyrelate to our product pipeline.
Individual Performance Assessment
Our assessment of performance against the corporate goals established by the board of directorsfor the CEO and the goals established by the Committee and/or the CEO for the other NEOs, aswell as an assessment of the individual’s importance to the Company’s future performance.
NEO Grant History and Retention Considerations
Our evaluation of each NEO’s grant history and prior grant size amounts. For retentionpurposes, the Committee also assesses the amount of outstanding unvested and/or vested butunexercised stock options and other equity awards (if applicable) held, including whether suchawards are “in-the-money.”

In applying this framework, the number of shares underlying the annual equity awards (on an options-equivalent basis) granted in 2019 to our CEO and CSO (as well as our other Named Officers in 2015 consisted of long-term compensation, which exceeds the corresponding average percentage for the companies included in the 2015 Radford Global Life Sciences Survey by 18% and 24%, respectively. Based on these metrics, our compensation structure is more heavily weighted toward long-term components versus short-term pay, thus promoting a long-term perspective among our executives.

Despite the reductions in theemployees, generally) was set 10% lower compared to 2018. The 2019 annual grant of stock optionsawards to our Named Officersother NEOs are described above,in greater detail below. With respect to our CEO and CSO, the grant date fair value (as determined accordingof their 2019 annual equity awards was nearly 22% lower than in 2018.

Annual Stock Option Awards

As in years past, stock options remained the Black-Scholes model for valuing stock options)principal component of the annual equity awards granted to our NEOs in 2019 (comprising 70% of each NEO’s award). We have used stock options granted in 2015such a prominent manner because they are inherently performance-based, requiring stock price appreciation before there is higher thanany real value earned, and simple. No amount of time will make a stock option deliver any value unless the Black-Scholes grant date fair value of the larger number ofcompany’s stock price increases. In addition, stock options granted to Named Officers in prior years. This increase inreward our NEOs for increasing shareholder value over the Black-Scholes valueentire 10-year option term, which we believe is consistent with the drug discovery and development cycle.

The 2019 stock options all have an exercise price of annual stock option awards (and the corresponding increase in the value of total compensation for the Named Officers in 2015) is attributable largely to the higher market value of our common stock on December 16, 2015, the date of these option grants, compared to prior years. On December 16, 2015,$372.46 per share, the average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market (used for calculatingon the grant date fair value) was $555.67,of grant. All of these grants consist of non-qualified stock options, which vest ratably over a period of four years. Except as compared to $399.66 on December 31, 2014set forth below in the subsection “Compensation Dashboard—2019 Compensation Tables—Post-Employment Compensation,” stock option vesting ceases, and $270.43 on December 13, 2013, the respective 2014 and 2013 grant dates.unvested stock options are forfeited, upon termination of employment.

Annual PSUs

In line with the goal of maintaining year-over-year consistency in making compensation decisions (regardless of stock price fluctuations), the Compensation Committee believes that the grant date fair value2019, we introduced PSUs as a secondary component of the optionannual equity awards for our CEO and CSO (30% of each such executive’s annual equity award (as determined accordingon an options-equivalent basis). The PSUs are performance-based because they will not vest and will not deliver realizable compensation if shareholders fail to benefit from a meaningful increase in TSR over the Black-Scholes model for valuing stock options) is notlong-term performance period.

The PSUs have a primary performance period of five years from the most appropriate measure for evaluating thedate of grant. Rather, the Compensation Committee focuses more on the percentage of Regeneron's potential future share price appreciation that is shared by meansBetween 50% and 225% of the award with the executive, expressed as thetarget number of shares underlying the option award relativePSUs granted to the numbereach executive (i.e.,between 50% and 225% of outstanding shares.

In recent years, we have experienced significant growth in employees to support our research & development and commercialization efforts. From 2012 to 2015, we increased our employee base by approximately 121%. While the number of recipients of stock awards continued to increase given our practice of making initial stock option awards to all new employees and annual stock option awards to eligible employees whose performance is determined to merit an annual grant, we managed our utilization of stock awards judiciously, reducing our burn rate from the 2012 level and achieving a three-year burn rate average of 4.1% in 2015, in line with our current burn rate goal of 4%. We achieved this reduction through implementing three consecutive double-digit percentage decreases in the number of shares underlying annual stock option awards, without eliminating the broad-based nature of our equity compensation program.

Regeneron Stock Utilization vs. Headcount

GRAPHIC

Burn rate calculated by dividing the number of shares subject to equity awards (time-based and performance-based stock options and restricted stock) granted during the year by the weighted-average number of shares of common stock (including unvested restricted stock) and Class A stock outstanding during the year. A multiplier of 2 is applied to restricted stock awards. Headcount numbers based on the number of employees as of December 31 of the applicable year.

In addition, the terms of the PSU awards provide the recipient an opportunity for accelerated vesting after four years if performance is strong, as measured against four-year cumulative TSR goals derived from the same compound annual growth rates used to calculate the cumulative TSR goals for the five-year performance period.

If no PSUs have vested at the end of the five-year performance period as a result of not having achieved the threshold cumulative TSR goals, the recipient will have an opportunity to earn a payout at threshold (50% of the target number of PSUs) if the Company’s cumulative TSR over such five-year period exceeds, on a relative basis, the cumulative TSR of the Nasdaq Biotech Index (composite return) by at least 200 basis points. The rationale for the minimum payout for exceeding the industry five-year index is that there may be circumstances in which Regeneron outperforms the broader market without delivering a positive return, such as in the last three years whencase of a recession or industry-wide developments outside management’s control.

Annual RSAs

In 2019, we implementedintroduced time-based RSAs as a secondary component of the stock option award reductions described above, we managed eitherannual equity awards for our NEOs other than our CEO and CSO as part of the Company-wide decision to decrease our burn rate orintroduce an RSA/RSU component to keep the percentage increaseregular long-term incentive mix for broad-based employees. RSAs comprise 30% of participating NEOs awards on an options-equivalent basis. We believe diversifying the mix of equity awards in our burn rate significantly belowthis manner responds to shareholder feedback about dilution (burn rate) and retention, as well as employee input. Each such RSA vests 50% on the percentage increasesecond anniversary of the date of grant and 50% on the fourth anniversary of the date of grant, which is a more backloaded vesting schedule than is typical in the industry.

Special RSAs to Certain NEOs

We supplemented our annual equity awards in 2019 with highly targeted grants of time-based RSAs/RSUs to certain key employees (including three of our NEOs) to further promote employee retention and reward exceptional performance. Based on this determination, in December 2019 Mr. Landry and Mr. Van Plew each received 5,000 RSAs and Dr. Murphy received 10,000 RSAs. Each such RSA vests on the fourth anniversary of the date of grant to promote long-term employment.

PERQUISITES AND PERSONAL BENEFITS

Similar to other employees, our NEOs may participate in Company-wide health, disability, life insurance, and other benefit plans, as well as our 401(k) Savings Plan. See details concerning the 401(k) Savings Plan in the subsection “Compensation Dashboard—Additional Compensation Information—Perquisites and Personal Benefits.” Our NEOs are eligible to receive a limited number of additional perquisites. These include financial and tax planning assistance, which are taxable benefits.

In addition, our employees. The 2015 increaseCEO is entitled to life insurance, long-term disability, medical malpractice insurance premiums, and additional tax and financial planning services pursuant to his employment agreement. These are described in our burn rate comparedfootnote 4 to the prior yearSummary Compensation Table.

Our CEO and CSO are also eligible for various benefits under our Company security policy, which was approved by the board of directors in 2015 for the purpose of ensuring increased efficiencies and providing a more secure environment for these executives. Based on the recommendation of an independent, third-party security study, our security policy and related guidelines require our CEO and CSO (as well as their spouses and children when they accompany them) to use, as much as practicable, Company-provided aircraft for all business and personal air travel.

Additional information regarding perquisites and other personal benefits provided to our NEOs in, or with respect to, 2019 is wholly attributable to the rapid hiring of new key employees (as evidenced by a 47% increasegiven in the number of employees over the same period), not increased sharing with our Named Officers (whose stock options grants declined).

Market Competitiveness and Employee Retention

In determining the appropriate size of stock option awardsapplicable footnotes to executives, including the Named Officers, the Compensation Committee primarily considers the number of shares underlying the awards relative to the number of basic shares of common stock outstanding and not the grant date fair value of the award (as determined according to the Black-Scholes model). The Compensation Committee is therefore able to evaluate such grants on a consistent basis as compared to other companies and regardless of fluctuations in the price of Regeneron's or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price. The following chart displays the 2015 annual stock option award to our Chief Executive Officer as a percentage of the total basic shares outstanding, as compared to the 75th percentile and the 50th percentile of the companies included in the 2015 Radford Global Life Sciences Survey, showing that the size of his 2015 annual award was significantly below the 75th percentile and only slightly above the 50th percentile. It also shows that this award was below the 50th percentile of our Biotech R&D Peers.

POTENTIAL SEVERANCE PAYMENTS

We believe that the structure offollowing three points are key to understanding our executive compensation program encourages innovation, attracts talent with entrepreneurial spirit, increases employee engagement, and improves employee retention and the continuity of executive leadership during a critical period of growth. We regard our stock option grants as a key employee and executive retention tool. As stock option awards to our employees vest over time, generally over four years, they provide an incentive for the employee to continue to contribute to our success. Historically,

stock options have helped us maintain a motivational level of total compensation for our Named Officerschange-in-control and other eligible employees, while conserving the Company's cash. We believe that this has helped us to successfully grow and manage employee attrition, as evidenced by our 2015 employee turnover of approximately 6%, which compares favorably to the average employee turnover of approximately 18% for the life sciences sector based on the Fourth Quarter 2015 Radford Global Life Sciences Trends Report. In addition, stock options have allowed us to attract and retain entrepreneurial employees and foster an ownership culture. Moreover, granting stock options as long-term incentives to executives is standard practice in our industry and is an important part of our effort to attract, retain, and motivate high-quality talent.severance provisions:

In light of these considerations, we continued our practice of annual stock option grants in 2015, although we again (for the third consecutive year) reduced the number of shares underlying the annual stock option awards to the Named Officers as described above to reduce the potential dilutive impact of executive awards without adversely affecting the effectiveness of our executive compensation program, which has successfully motivated our senior management team to deliver high operating performance and shareholder value. In light of the fierce competition for talent in our industry, we believe that it is important to continue to motivate our existing employees, including the Named Officers, through stock option awards and to ensure that they share in the success of Regeneron.

We provide our Named Officers with a limited number of perquisites and other personal benefits. These benefits, which are described in greater detail under "Section 4 – Elements of Executive Compensation – Perquisites and Other Personal Benefits" below, are periodically reviewed by the Compensation Committee.

Outstanding equity award agreements (with the exceptions and qualifications described in the subsection “Compensation Dashboard—Additional Compensation Information—Potential Severance Payments”) for all employees other than Dr. Vagelos include a governance best-practice “double trigger” provision for the acceleration of vesting of awards granted thereunder only upon a without-cause termination by the Company within two years of a change in control.
We have apolicy against excise tax gross-up provisionsfor payments contingent on a change in control of Regeneron in contracts, compensatory plans, and other arrangement with the Company’s officers (including NEOs) with the exception of the CEO under his existing employment agreement or amendments to it.
Regeneron hasno pension, deferred compensation, or retirement plansother than our 401(k) Savings Plan described above.

OverviewOUR COMPENSATION PROCESSES

OUR COMPENSATION COMMITTEE

The Compensation Committee is responsible for overseeing the Company'sCompany’s general compensation objectives and programs. The Compensation Committee evaluates the performance of our Named OfficersNEOs and approves compensation for the Named Officers (intheir compensation—in the case of the Chief Executive Officer,CEO, subject to first obtaining the approval of the non-employee members of the board of directors).directors. The Compensation Committee operates under a written charter adopted by the board of directors and regularly reviews and reassesses the adequacy of its charter. A copy of the current charter is available on our website atwww.regeneron.comunder the "Corporate Governance"“Corporate Governance” heading on the "Investors“Investors & Media"Media” page.

Members of our senior management play a significant role in the overall executive compensation process and assess performance of other officers. They also recommend, for Compensation Committee approval, salary, bonus, and stock option grant budgets for non-officers and make specific recommendations for salary increases, bonuses, and equity award grants for other officers. For our Named Officers (other than our Chief Executive Officer), recommendations to the Compensation Committee regarding their compensation are made by, or with the approval of, our Chief Executive Officer, who also evaluates their performance. Our Chief Executive Officer's performance is evaluated directly by the Compensation Committee based on our overall corporate performance

against annual goals that are approved by the board of directors at the beginning of each year, as discussed in more detail below.

The Compensation Committee has the sole authority to retain, at our expense, one or more third-party compensation consultants to assist the Compensation Committee in performing its responsibilities and to terminate the services of the consultant if the Compensation Committee deems it appropriate. In 2015, the Compensation Committee utilized the services of Frederic W. Cook & Co. to assist it in fulfilling its responsibilities. In order to maintain its independence, Frederic W. Cook & Co. was retained directly by the Compensation Committee and performed projects at the Compensation Committee's direction. The Compensation Committee's consultant reviews management recommendations on compensation plans, budgets, and strategies and advises the Compensation Committee on regulations and trends in executive compensation nationally and specifically in the pharmaceutical and biopharmaceutical industries. The Compensation Committee's consultant provides comparative compensation information for our Chief Executive Officer and other senior executives (using the Peer Group and other compensation data as described below), reviews senior management's compensation recommendations for other officers, including the other Named Officers, and provides general advice to the Compensation Committee on compensation matters, including facilitating the articulation and periodic review of the Company's compensation philosophy.

Annual salaries for the following year and year-end bonusescash incentives and stock option awards or other year-end equity awards for all employees are determined in December of each year based on Company and individual performance, as well as other factors, includingwhich may include compensation trends among our Peer Group and in the biotechnology industry in general. The 2015 salaries and 2014 year-end bonuses and stock option awards for our Named Officers were established by the Compensation Committee in December 2014. In November and December 2015, the Compensation Committee reviewed the performance of each of the Named Officers and presented its recommendations for 2016 salaries and 2015 year-end bonuses and equity awards for the Named Officers to the non-employee members of the board of directors for concurrence. With respect to our Chief Executive Officer,CEO, this process is formalized in the charter of the Compensation Committee,Committee’s charter, which specifies that the Compensation Committee is to annually present the proposed annual compensation of the Chief Executive OfficerCEO to the non-employee members of the board of directors for approval.

Peer Group

For purposes of setting compensation of our Chief Executive Officer, our Chief Scientific Officer, the other Named Officers, and other senior executives, we use comparative compensation information from a relevant peer group of companies ("Peer Group"). The companies in the Peer Group are selected by the Compensation Committee, with the assistance of Frederic W. Cook & Co., based on factors including, but not limited to, market capitalization, geographic location, number of employees, therapeutic focus, research and development expenditures, stage of development, total revenues, and product sales. The Company's trailing revenue size, number of employees, operating earnings, and market capitalization are all nearly in the middle of the range of the current Peer Group companies. The Peer Group is also meant to provide a representative sample of companies with which we compete for talent. The Compensation Committee periodically reassesses the composition of the companies within the Peer Group and makes changes as appropriate, taking into account factors such as changes in the Company's market capitalization and merger-and-acquisition activity impacting the existing Peer Group companies. In September 2015, the Compensation Committee approved a new Peer Group based on the recommendation of its compensation consultant, Frederic W. Cook & Co.. The changes to the Peer Group were as follows: (i) elimination of Cubist Pharmaceuticals, Inc. in light of the fact that it had been acquired by Merck & Co., Inc.; (ii) elimination of Seattle Genetics, Inc. due to its market capitalization being significantly below Regeneron's; and (iii) addition of Alkermes plc and Alnylam Pharmaceuticals, Inc., both of which are biopharmaceutical companies with a business model the Compensation Committee considered similar to Regeneron's. In approving the new Peer Group, the Compensation Committee also took into account that, as of the approval date, Regeneron was the median company in the Peer Group based on market capitalization, revenues for the last four completed quarters,non-employee directors and the then-available reported number of employees, as shown in the table below.

Regeneron's Biotech R&D Peer.

In making its compensation decisions in December 2015, the Compensation Committee used data from publicly filed proxy statements of the companies in the Peer Group (as compiled by its compensation consultant) to review each element of compensation of our Named Officers against their peers in the Peer Group as well as their total annual compensation in relation to the Peer Group, while taking into account various factors such as the executive's performance, past compensation history, experience, and the role in the Company's success. We use Peer Group data as a point of reference for measurement, but Peer Group data do not represent the only factor considered and there is no targeted pay level percentile. Further, in its review of the Peer Group data, the Compensation Committee also considers the practices of the 10-company sub-group of peers viewed as having businesses and drug discovery cultures that are most similar to Regeneron's, with similarly-sized employee bases (marked with an asterisk

in the table above and referred to as "Biotech R&D Peers"). The Compensation Committee retains discretion in determining the nature and extent of the use of Peer Group data. In addition, in 2015 management and the Compensation Committee reviewed compensation data for biotechnology companies from the 2015 Radford Global Life Sciences Survey (comprising U.S. public biotechnology and pharmaceutical companies that have between 800 and 15,000 employees) to obtain a general understanding of current compensation practices and to assess overall competitiveness of our compensation program.

including by taking into consideration the following factors:

the fact that Frederic W. Cook & Co. did not provide any other services to the Company;

the amount of fees received from the Company by Frederic W. Cook & Co. as a percentage of its revenue;

the policies and procedures of Frederic W. Cook & Co. designed to prevent conflicts of interest;

the absence of any significant business or personal relationship between Frederic W. Cook & Co. and any member of the Compensation Committee;

the fact that Frederic W. Cook and the representative of Frederic W. Cook & Co. to the Company did not own any stock of the Company; and

the absence of any material business or personal relationship between Frederic W. Cook & Co. and any executive officer of the Company.

The Compensation Committee's evaluation was based in part on a representation letter from Frederic W. Cook & Co.. On the basis of this evaluation, the Compensation Committee concluded that the engagement of Frederic W. Cook & Co. did not raise any conflicts of interest.

Stock Ownership Guidelines

To further align the interests of senior management with the interests of shareholders and promote a long-term perspective, the board of directors has adopted stock ownership guidelines for members of senior management, including the Named Officers, and the members of the board of directors. The guidelines are reviewed periodically by the Corporate Governance and Compliance Committee. Pursuant to these guidelines, these individuals are expected to meet share ownership targets that are determined based on their position and their base salary. The share ownership targets are as follows:

Chairman of the Board and Chief Executive Officer, six times (6x) base salary;

Chief Scientific Officer, three times (3x) base salary;

Executive/Senior Vice Presidents, two times (2x) base salary; and

non-employee members ofare also involved in reviewing the board of directors, six times (6x) the annual retainer.

Covered individuals who do not currently meet these guidelines have five years from becoming subject to the policy to reach their target. Members of senior management who are

hired or promoted, and directors who join the board of directors, have five years from such date to reach their target. Shares held directly, shares held indirectly through our 401(k) Savings Plan, shares held in trust, and shares held by immediate family members residing in the same household are included in determining an individual's share ownership. Unexercised stock options and unvested restricted stock are not considered ownedCompany’s performance for purposes of these guidelines. All directors and officers have either met their respective share ownership targets or are still withinsetting the five-year period for achieving compliance.annual cash incentive.

Say-on-Pay Response

Our shareholders are provided with an opportunity to cast a non-binding, advisory vote every three years on our executive compensation program. Our shareholders most recently had the opportunity to cast advisory say-on-pay votes at our annual shareholder meeting held in June 2014, at which approximately 62% of the votes cast supported the advisory vote proposal on our executive compensation program. Management and the Compensation Committee carefully considered the results of the most recent say-on-pay vote. Senior members of our management as well as the Chairman of the Compensation Committee subsequently spent a significant amount of time speaking with some of our key shareholders about executive compensation and corporate governance. As part of our 2014 engagement effort, we discussed these issues with shareholders collectively representing approximately 47% of the shares of common stock outstanding as of December 31, 2014 (excluding shares held our directors and executive officers and Sanofi). Following the 2014 discussions, we implemented several changes to our executive compensation program and continued the implementation of our existing compensation and governance initiatives. A summary of the relevant changes and initiatives adopted after the most recent say-on-pay vote is provided below.

We reduced the number of shares underlying the 2014 annual stock option awards to the Named Officers by an average of 16% compared to the prior year (without giving effect to a grant to our Chief Financial Officer, who did not receive an annual stock option award in 2013 because he joined the Company in September 2013).

We eliminated certain perquisites of our Chief Executive Officer and our Chief Scientific Officer we considered no longer consistent with our overall compensation program, including, in the case of our Chief Executive Officer, a tax gross-up related to legal, tax, and financial planning advisory services.

Table of Contents

We adopted a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in contracts, compensatory plans, or other arrangements with the Company's executive officers, including the Named Officers (other than the existing employment agreement with our Chief Executive Officer or any amendments thereto, which we expressly exempted).
We provided additional information regarding compensation decisions and our compensation philosophy in the Compensation Discussion and Analysis of our 2015 proxy statement to better communicate to our shareholders what drives compensation decisions at Regeneron.

We will continue to consider the outcome of our past and future advisory vote results. Our shareholder engagement efforts and implementation of compensation and governance initiatives continued in 2015, as described further below under "2015 Shareholder Outreach."

2015 Shareholder Outreach

We have instituted an ongoing shareholder outreach program through which we seek input frommake our institutional investors and other shareholders regarding our executive compensation and other governance practices, and implement appropriate changes based on this input. We value shareholder views and insights and believe that constructive and meaningful dialogue allows us to develop broader relationships with investors over the long-term and builds informed relationships that promote transparency and accountability. We continued our shareholder outreach efforts in 2015 and engaged in discussions with shareholders collectively representing approximately 47% of the shares of common stock outstanding as of December 31, 2015 (excluding shares held our directors and executive officers and Sanofi). Below is a summary of recent changes we have adopted based on shareholder feedback and other relevant considerations:

Continue to implement corporate governance best practicesAdopted majority voting standard in the election of directorsJanuary 2016

Consideration of Risk in Company Compensation Policies

The Compensation Committee regularly reviews the Company's compensation and benefits programs, including its executive compensation program and its incentive based compensation programs for commercial personnel. Our compensation and governance-related policies are further enhanced by our stock ownership guidelines applicable to our senior officers and our policy regarding recoupment or reduction of incentive compensation of our officers and other specified employees for compliance violations, as well as a policy against hedging and pledging of our securities by our directors and employees, including the Named Officers. We have also adopted a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in

contracts, compensatory plans, or other arrangements with the Company's executive officers, including the Named Officers (other than the existing employment agreement with our Chief Executive Officer or any amendments thereto, which we expressly exempted). These policies evidence Regeneron's continued commitment to robust corporate governance and are meant to reduce compensation-related risks and ensure greater alignment of the interests of our employees, including the Named Officers, and those of the Company and our shareholders.

We believe that the Company's programs balance risk and potential reward in a manner that is appropriate to the Company's circumstances and in the best interests of the Company's shareholders over the long term. We also believe that

53

the Company's compensation and benefits programs do not create risks that are reasonably likely to have a material adverse effect on the Company.

Tax Implications

Section 162(m) of the Internal Revenue Code limits the deductibility for federal income tax purposes of compensation in any year paid to the Chief Executive Officer and the other Named Officers (other than the Chief Financial Officer) to the extent such compensation exceeds $1 million and does not qualify as "performance-based" compensation as defined under Section 162(m) of the Internal Revenue Code. The Company has adopted (and the shareholders approved at the 2015 annual shareholder meeting) the Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan. Awards under the Plan (as well as awards under the previously approved Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan) may, but

are not required to, be subject to the attainment of performance goals in order to qualify for this performance-based compensation exception. The Compensation Committee has implemented the Cash Incentive Bonus Plan for annual cash bonuses of the Named Officers in respect of performance in 2016.

The Compensation Committee takes into account the deductibility of compensation in determining Named Officer compensation. However, the Compensation Committee reserves the right to use its judgment to authorize compensation payments that are not deductible, such as when the Compensation Committee believes that such payments are necessary to maintain the flexibility needed to attract talent, promote executive retention, or reward performance, or as required to comply with the Company's contractual commitments. As noted above, compensation attributable to stock options generally qualifies as "performance-based" compensation and, as such, receives favorable treatment under Section 162(m) of the Internal Revenue Code.

Section 4 – Elements of Executive Compensation

Our executive compensation program currently has five components:

base salary;

annual cash bonus;

annual equity awards typically consisting of stock options;

certain perquisites and other personal benefits; and

potential severance benefits.

Base Salary

We provide the Named Officers and other employees with base salary to compensate them for services rendered during the fiscal year and provide them withon a regular, monthly income. In determining base salaries for our Named Officers, the Compensation Committee considers the executive's scopepre-set schedule. The meetings at which such grants are approved are generally scheduled well in advance of responsibilities, experience, annual performance, and future potential or role in future success. The Compensation Committee also considers base salaries for comparable positions in our geographic region, competitive salary practices of companies in the Peer Group and the broader biopharmaceutical industry, and annual inflation levels.

For each of 2015 and 2016, each of the Named Officers received a merit increase of 3.5% of his 2014 and 2015 base salary, respectively (which were in addition to the other increases discussed for the Named Officers below). In addition, for 2015, Dr. Schleifer received a base salary increase of

$91,300, which aligned his base salary with that of the median of the companies included in the 2014 Radford Global Life Sciences Survey and below the median of the Peer Group (as in effect in 2014), and Dr. Yancopoulos received a base salary increase of $77,600 to set his base salary at 85% of Dr. Schleifer's. Dr. Yancopoulos's cash compensation, including base salary, is set at 85% of Dr. Schleifer's, which we believe is more appropriate for him in light of the absence of meaningful comparative data for similarly situated executives. Further, for 2015, Dr. Stahl received a $39,200 base salary increase in connection with his promotion to Executive Vice President, Research and Development and Mr. Terifay received a $50,000 base salary increase, in each case to better align his base salary with relevant industry comparative information. For 2016, Dr. Stahl and Mr. Landry received a $50,000 base salary increase each in order to better align their base salaries with relevant industry comparative information. The determinations regarding the 2015 and 2016 merit increases were based on broad-based national data for high-performing, larger biotechnology companies. In each of 2015 and 2016, the base salaries of the Named Officers were set at or below the median of the Peer Group (other than with respect to Dr. Yancopoulos, whose cash compensation, including base salary, is set at 85% of Dr. Schleifer's (as noted above)).

Annual Cash Bonus

It has been our practice to offer annual cash bonus opportunities to our Named Officers. The Compensation Committee focuses exclusively on our overall corporate performance when determining the annual cash bonus for our Chief Executive Officer and Chief Scientific Officer. The cash bonuses of the other Named Officers are based both on overall corporate performance and their individual contributions and performances during the year. We historically had no formal bonus plan and the award of any bonus to a Named Officer was based on an assessment of corporate and, in the case of Named Officers other than Dr. Schleifer, individual performance. We believe that this approach, rather than working from a rigid bonus formula or plan, was beneficial given the growth trajectory of the Company and its rapid transformation over the past few years from a development-stage company to a fully integrated, commercial-stage biopharmaceutical company. In 2015, the Company adopted, and the shareholders approved, the Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan. The Compensation Committee has implemented the Cash Incentive Bonus Plan for annual cash bonuses of the Named Officers in respect of performance in 2016.

The 2015 cash bonus target for the Chief Executive Officer was 100% of his base salary. In December 2015, the board of directors approved an increase in the Chief Executive Officer's cash bonus target to 120% of his base salary to bring Dr. Schleifer's target annual cash compensation to the median of the companies included in the 2015 Radford Global Life Sciences Survey. For 2016, Dr. Schleifer's target cash compensation remained below the median of the Peer Group. Consistent with Regeneron's historical practice, the increase was given effect in the calculation of Dr. Schleifer's cash bonus paid in respect of 2015. The Chief Executive Officer

recommended 2015 target bonuses for the other Named Officers, which were reviewed and approved by the Compensation Committee. In December 2015, the Compensation Committee increased the cash bonus target for Mr. Landry and Mr. Terifay to 50% and 60% of their respective base salaries; consistent with Regeneron's historical practice, these increases were given effect in the calculation of their cash bonuses paid in respect of 2015. In determining the cash bonus targets for 2015 for Mr. Landry, Dr. Stahl, and Mr. Terifay, the Compensation Committee took into consideration the compensation of similarly situated executive officers at companies in the Peer Group and, in the case of Mr. Terifay, also his promotion to Executive Vice President, Commercial.

In determining the cash bonus target for Dr. Yancopoulos, the Compensation Committee took into consideration the importance of his scientific leadership as President of Regeneron Laboratories and Chief Scientific Officer and the significant contributions he has made to the success of the Company and, specifically, to the discovery and development of the Company's commercial products, its pipeline of internally developed product candidates, and its platform technologies.

The Compensation Committee determined that for Dr. Yancopoulos there were no meaningful comparative data relating to similarly situated executives and that his base salary, cash bonus, and annual stock option awards would be set at 85% of Dr. Schleifer's. The 2015 cash bonus target for Dr. Yancopoulos was 120% of his base salary (increased in connection with the increase of Dr. Schleifer's cash bonus target as described above). These cash bonus targets are consistent with the Company's emphasis on performance-based compensation and are set at or below the median of the Peer Group (other than with respect to Dr. Yancopoulos, whose cash compensation, including cash bonus, is set at 85% of Dr. Schleifer's).

In December 2015, our Named Officers were awarded the following cash bonuses, which were paid in January 2016.

depending upon performance during the year. Both the personal performance multiplier and the Company performance multiplier were determined by the Compensation Committee for each Named Officer based on the Committee's assessment of the Company's performance relative to the general corporate goals described below and, in the case of each of Mr. Landry, Dr. Stahl, and Mr. Terifay, the Named Officer's personal performance during the year.

The Compensation Committee determined that the Company's performance in 2015 well exceeded its 2015 corporate goals. These corporate achievements included the following:

47% growth in EYLEA® global net product sales as compared to 2014;

46% growth in our total revenues as compared to 2014;

19% growth in non-GAAP net income as compared to 2014 (non-GAAP net income is not a measure calculated in accordance with U.S. Generally Accepted Accounting Principles; see Appendix A for a definition of non-GAAP net income and a reconciliation of non-GAAP net income to net income);

advances in our EYLEA® franchise, including regulatory approval of EYLEA® for the treatment of visual impairment due to macular edema secondary to retinal vein occlusion and the treatment of visual impairment secondary to myopic choroidal neovascularization in the European Union; regulatory approval of EYLEA® for the treatment of diabetic retinopathy in patients with diabetic macular edema in the United States; and regulatory approval of EYLEA® for the treatment of retinal vein occlusion in Japan;

approval and launch of Praluent® (alirocumab) Injection, the first FDA-approved drug in a new class of drugs that lower LDL ("bad") cholesterol;

positive Phase 3 data for sarilumab from three Phase 3 studies in patients with rheumatoid arthritis (SARIL-RA-TARGET, SARIL-RA-EASY, and SARIL-RA-ASCERTAIN) and submission of a Biologics License Application for sarilumab with the FDA;

positive pivotal Phase 2b data for dupilumab in asthma and completion of enrollment of the dupilumab atopic dermatitis Phase 3 studies;

new collaboration agreement relating to fasinumab with Mitsubishi Tanabe Pharma Corporation for Japan, Korea, and nine other Asian countries, excluding China;

initiation of Phase 3 clinical study of REGN2222 for Respiratory Syncytial Virus;

continued growth of our clinical development pipeline, as evidenced by the submission of one Investigational New Drug Application with the FDA in 2015 and 13 product

candidates (consisting of one Trap-based and 12 fully-human monoclonal antibody product candidates based on the Company'sVelocImmune® technology) in clinical development as of December 31, 2015;

new global strategic collaboration with Sanofi to discover, develop, and commercialize antibody-based cancer treatments in the field of immuno-oncology; and

further important steps to support our current and future growth, including adding two new buildings in the Tarrytown campus providing nearly 300,000 square feet of additional laboratory and office space; significant progress with the construction of a new manufacturing facility in Limerick, Ireland; and increasing headcount on a year-over-year basis by approximately 47% as of December 31, 2015.

See "Section 1 – Summary – 2015 Performance Overview" above for additional information.

In recognition of these significant achievements, the Company performance multiplier for 2015 was set at 2.0.

With respect to 2015, the Compensation Committee approved a personal performance multiplier of 1.5 for each of Mr. Landry, Dr. Stahl, and Mr. Terifay. The personal performance component accounted for 40% of these officers' bonuses. The Company component was based on a Company performance multiplier that was determined based on the Company's overall corporate performance (as described above) against 2015 goals that were approved by the board of directors in January 2015. This Company performance component accounted for 60% of the bonuses awarded to Mr. Landry, Dr. Stahl, and Mr. Terifay. In the case of Drs. Schleifer and Yancopoulos, the Compensation Committee focused exclusively on our overall Company performance in 2015 (as described above) when determining their cash bonuses and did not utilize a personal performance multiplier.

In determining the personal performance multiplier for Mr. Landry, the Compensation Committee gave special consideration to Mr. Landry's leadership of and accomplishments in the Company's accounting and finance functions and his assumption of additional responsibilities since he joined the Company in September 2013. In the case of Dr. Stahl, the Compensation Committee focused on the progress and continued expansion of the Company's preclinical and clinical development pipeline, including the positive results from the Company's clinical trials reported in 2015, as summarized in "Section 1 – Summary – 2015 Performance Overview" above. In the case of Mr. Terifay, the Compensation Committee focused primarily on the continued commercial success of EYLEA® and the fact that EYLEA® U.S. net product sales in 2015 grew by 54% compared to 2014; the launch of Praluent® in 2015; and his leadership of the Company's commercial group, including the increase in his responsibilities in

connection with the expansion of the commercialization group to support the launch of Praluent® and the planned launches of sarilumab and dupilumab.

Annual Stock Option Awards

We have used stock option grants as the primary vehicle for offering long-term incentives and rewarding our Named Officers and other eligible employees. These time-based stock options generally vest at a rate of 25% per year over the first four years of the ten-year option term, subject to the executive's continued employment. We grant stock option awards to our Named Officers and other eligible employees based on their annual performance and their position and responsibilities with the Company. Each of our Named Officers generally receives an annual stock option grant and all of our other regular employees are also eligible for an annual stock option grant, subject to satisfactory performance. The number of stock options granted to each Named Officer is determined on a discretionary basis, rather than by a formula. The Compensation Committee primarily considers the number of shares underlying the awards relative to the number of basic shares of common stock outstanding and not the grant date, fair value of the award (as determined accordingwithout regard to the Black-Scholes model). The Compensation Committee is therefore able to evaluate such grants on a consistent basis as compared to other companies and regardlesstiming of fluctuations in the price of Regeneron'searnings or other companies' common stock. Further, focusing on the number of shares and the incremental sharing rate of potential future upside (rather than targeting a specific Black-Scholes grant date fair value) avoids rewarding officers with larger grant sizes following a decline in our stock price. While the Compensation Committee takes the estimated Black-Scholes grant date fair value of annual stock option grants into account, it does not necessarily determine its compensation decisions.

It has been the practice of our Compensation Committee tomajor announcements. We generally grant annual stock optionequity awards to eligible employees whose performance is determined to merit an annual grant, including the Named Officers,NEOs, at a meeting held during December. In 2015, stock option awards (all of which were non-qualified stock options) were granted to our Named Officers and other eligible employees on December 16, 2015.

Pursuant to the terms of the Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan, stock option awards are granted for so long as our common stock is listed on the NASDAQ Global Select Market, with an exercise price equal to the

average of the high and low sales price per share of our common stock as quoted on the NASDAQ Global Select Market on the date of the grant or, if such date is not a trading day, on the last preceding date on which there was a sale of our common stock on the NASDAQ Global Select Market.

All

We periodically evaluate the personal benefits and perquisites afforded to our NEOs. The Compensation Committee also regularly meets in executive session to discuss any of the stock options granted tomatters that fall within its responsibilities.

MANAGEMENT

Members of our Named Officerssenior management play a role in 2015 will vest ratably over a periodthe overall executive compensation process and assess performance of four years. Except as set forth below underother officers. They also recommend for the heading "Post-Employment Compensation" on page 66, stock option vesting ceases,Compensation Committee’s approval the salary, cash incentive, and unvested stock options are forfeited, upon termination of employment. The use of only time-based stock options is consistent with the Company's practice prior to 2008equity grant budgets for non-officers and since 2012.

Our Named Officers received a grant of time-based stock options on December 16, 2015, as set forth below. The annualmake specific recommendations for salary increases, cash incentives, and equity grants shown below reflected an average reduction of 15% compared to 2014for other officers. For our NEOs (other than Mr. Terifay's award, which remained at the 2014 level dueour CEO), recommendations to his promotion to Executive Vice President, Commercial). This decrease constituted the third consecutive double-digit percentage decrease in the annual grant of stock options to our Named Officers, in each case following outstanding TSR performance. In reducing the size of 2015 annual stock option awards to the Named Officers, the Compensation Committee soughtregarding their compensation are made by, or with the approval of, our CEO, who also evaluates their performance. Our CEO’s performance is evaluated directly by the Compensation Committee based on the Company’s overall corporate performance against annual goals that are approved by the board of directors at the beginning of each year, as discussed above.

COMPENSATION-RELATED MATTERS  /  COMPENSATION DISCUSSION AND ANALYSIS

SHAREHOLDER INPUT AND OUTREACH

We believe in casting a broad net for information, and think it is very important to reducereach out to our shareholders for ideas, input, and direct feedback. We do this formally through our triennial say-on-pay votes, as well as through discussions with our shareholders both in connection with our annual shareholder meetings and in the potential dilutive impact“off-season,” where we discuss compensation, governance, and other issues of new equity awards without adversely affectingimportance and interest to our shareholders. In addition, on a more informal basis, we engage with our shareholders through regular investor relations channels, governance engagements, industry conferences, and informal exchanges in other settings.

Say-on-pay vote.Our shareholders are provided with an opportunity to cast a non-binding, advisory vote every three years on our executive compensation program. You will have that opportunity again at the effectiveness2020 annual shareholder meeting. Our most recent advisory say-on-pay vote was held at our 2017 annual shareholder meeting, at which this advisory proposal was approved by 67% of the votes cast. As has been the case with previous say-on-pay votes, management and the Compensation Committee carefully considered the result of this say-on-pay vote and subsequently solicited further feedback from our key shareholders on compensation and governance matters. In the last several years, following our two most recent advisory say-on-pay votes, we implemented several changes to our executive compensation program and continued the implementation of our existing compensation and governance initiatives. These and other recent changes are summarized in the table below following the description of our shareholder outreach.

Shareholder outreach.In addition to the more formal input of the say-on-pay vote discussed above, we maintain a robust shareholder outreach program (both in connection with our annual shareholder meetings and in the “off-season”) through which has successfully motivatedwe seek input from shareholders and environmental, social, and governance (“ESG”)-focused groups regarding our seniorexecutive compensation and other governance practices, and implement appropriate changes based on this input.

Our annual shareholder outreach program is quite extensive – last year we approached shareholders collectively representing nearly 60% of the shares of common stock outstanding as of December 31, 2019 (excluding shares held by our directors and executive officers and Sanofi), which we refer to as “public shareholders”. As part of our outreach, we engaged in direct one-on-one discussions with over 50% of our public shareholders as well as both leading proxy advisory firms. We encourage director participation in our outreach, and our Compensation Committee Chair led many of these discussions. Shareholder feedback is discussed with management teamand, depending on the topic, relayed for consideration to deliver high operating performancethe appropriate committee of the board of directors (typically the Compensation Committee or the Corporate Governance and Compliance Committee), the full board, or both. In recent years, shareholder value. The reduction also tookinput resulted in specific changes to our compensation and corporate governance practices and policies, including the changes discussed below.

Our 2019 outreach discussions built on an active outreach program in prior years and focused on, among other matters, equity compensation matters, including investor views on performance-based equity, the appropriate scope of equity compensation programs, and acceptable burn rate and dilution. As discussed elsewhere in this CD&A, influenced by shareholder feedback and input from the past several years, in December 2019 we introduced PSUs as a component of the annual equity awards for our CEO and CSO (as well as the Chairman of the Board). This change and other changes we have adopted in recent years while taking into account the increaseshareholder feedback, which we believe demonstrate our continued commitment to good governance, are outlined in the Company's stock price in recent years. We will continue to assess the number of stock options that will be awarded to the Named Officers as annual merit grants.table below.

Recent Changes Adopted Based on Shareholder Feedback

What We HeardWhat We DidWhen We Did It
Concern about size of NEO equity awardsImplemented seven consecutive reductions in the number of option-equivalent shares underlying the annual equity awards to most of our NEOs, regardless of the stock price on the grant date2013–2019
Support for all-employee equity compensation strategy, but concern about resulting burn rate

Maintained our all-employee equity compensation strategy while addressing concerns about the resulting burn rate using a two-part approach:

Named Officer1   

Reduce equity award grant guidelines: size of CEO equityawards reduced by almost 60% over the last seven years;and

2  Introduce (starting in 2019) full-value awards for a portion of the annual equity awards to eligible employees: PSUs for 30% of CEO/CSO/Chairman 2019 annual equity awards; RSAs/RSUs for 30% of 2019 annual equity awards for other NEOs and certain other executives; and RSAs/RSUs for 40% of 2019 annual equity awards for other employees.



2013–2019





Stock
Option Award1


These changes have allowed us to maintain relatively stable burn rate despite a 316% increase in the number of employees from the end of 2012 through 2019.

2019 burn rate was lower by 1.1% despite hiring 730 new employees during the year.

 
Preference for further pay-for-performance alignmentAs part of the 2019 annual equity awards to our CEO and CSO, we introduced PSUs with rigorous performance goals tied to the Company’s TSR (target = 61% TSR over five years).2019
Desire for more clarity regarding the process for determining annual cash incentivesEnhanced the existing process for determining 2019 annual cash incentives and provided more detailed disclosure about the Compensation Committee’s determination of the Company performance multiplier. See “Components of Executive Pay: What We Pay and Why We Pay It – Annual Cash Incentives” above for more information.2019–2020
Concern about compensation program for non-employee directors and the Chairman of the Board

Introduced a new compensation program for our non-employeedirectors and the Chairman of the Board in November 2018. Asa result:

Leonard S. Schleifer, M.D., Ph.D.   Reduced by nearly 50% the grant date fair value ofequity awards to both the non-employee directors andthe Chairman of the Board (granted in January 2019 andDecember 2018, respectively); and

INDEPENDENT COMPENSATION CONSULTANT

The Compensation Committee has the sole authority to retain, at the Company’s expense, one or more third-party compensation consultants to assist the Compensation Committee in performing its responsibilities and to terminate the services of the consultant if the Compensation Committee deems it appropriate. In 2019, the Compensation Committee (and, as discussed above with respect to non-employee director compensation matters, the Corporate Governance and Compliance Committee) utilized the services of Frederic W. Cook & Co. In order to maintain its independence, the Compensation Committee retained Frederic W. Cook & Co. directly and Frederic W. Cook & Co. performed services for the Compensation Committee exclusively at the Compensation Committee’s direction. The Compensation Committee periodically evaluates the independence of its compensation consultant. In accordance with applicable listing standards of the NASDAQ Stock Market LLC and SEC rules, in 2019 the Compensation Committee evaluated the independence of Frederic W. Cook & Co., including by taking into consideration the following factors:

the fact that Frederic W. Cook & Co. did not provide any other services to the Company (other than those provided to the Corporate Governance and Compliance Committee);
 

George D. Yancopoulos, M.D., Ph.D.

the amount of fees received from the Company by Frederic W. Cook & Co. as a percentage of its revenue;
146,815 

Robert E. Landry

the policies and procedures of Frederic W. Cook & Co. designed to prevent conflicts of interest;

Neil Stahl, Ph.D.

the absence of any significant business or personal relationship between Frederic W. Cook & Co. representatives and any member of the Compensation Committee;
68,638 

Robert J. Terifay

the fact that Frederic W. Cook and the representatives of Frederic W. Cook & Co. to the Company did not own any stock of the Company; and
40,000 
​ the absence of any material business or personal relationship between Frederic W. Cook & Co. or its representatives and any executive officer of the Company.

These stock options all have an exercise price

The Compensation Committee’s evaluation was based in part on a representation letter from Frederic W. Cook & Co. On the basis of $555.67 per share,this evaluation, the averageCompensation Committee concluded that the engagement of Frederic W. Cook & Co. did not raise any conflicts of interest.

The Compensation Committee’s consultant reviews management recommendations for compensation plans, budgets, and strategies, and also advises the Compensation Committee on how regulations and trends in executive compensation nationally and specifically in the pharmaceutical and biopharmaceutical industries may be relevant to the Company. It also assists with developing the Peer Group, provides comparative compensation information for our CEO and CSO and the other members of the highBoard (using the Peer Group and low sales price per shareother compensation data as described below); reviews senior management’s compensation recommendations for other officers, including the other NEOs; and provides general advice to the Compensation Committee on compensation matters, including facilitating the articulation and periodic review of the Company’s compensation philosophy or replenishment of our common stocklong-term equity incentive plan.

PEER DATA

For purposes of setting our NEOs’ and other senior executives’ compensation, we use comparative compensation information from a relevant peer group of companies (referred to in this proxy statement as quoted“Peer Group”). We select the companies in the Peer Group with the assistance of Frederic W. Cook & Co. based on factors including, but not limited to, the NASDAQ Global Select Market on the date of grant.

How did we determine the size of our 2015 annual Named Officer stock option awards?


The size of the time-based stock option awards granted to our Named Officers were based on the following six factors:

past Company practices (i.e., history of grants to relevant executives);

an assessment of each Named Officer's 2015 performance against the Named Officer's goals, as established by our CEO (in the case of the Named Officers other than our Chief Executive Officer) and the Compensation Committee (in the case of our Chief Executive Officer), as described above under "– Annual Cash Bonus";

Regeneron's significant corporate accomplishments in 2015;

recognition that cash compensation of the Named Officers is generally positioned at or below the median of the Peer Group despite the fact that Regeneron is a high-growth, high-performing company, which supports a higher level of equity grants;


an evaluation of the awards as a percentage of the total basic shares outstanding as compared to Peer Group and survey data, in particular the 2015 Radford Global Life Sciences Survey (see "Section 2 – Analysis of 2015 Executive Compensation Based on Compensation Objectives – Market Competitiveness and Employee Retention"); and

the increase in the Company stock price since the annual stock option awards in 2014 and prior years, with the resulting increase in the grant date fair value of the 2015 annual stock option awards (as determined according to the Black-Scholes model for valuing stock options), which contributed to the decision to implement the third consecutive double-digit percentage reduction in the annual grant of stock options to our Named Officers (for information regarding our burn rate since 2012, see "Regeneron Stock Utilization vs. Headcount" on page 48).

As noted above, Dr. Yancopoulos's 2015 annual stock option award was set at 85% of Dr. Schleifer's (consistent with other elements of his compensation and our historical practice).

We periodically reassess the composition of perquisitesthe Peer Group and other personal benefits. make changes as appropriate, taking into account factors such as changes in the Company’s market capitalization and merger-and-acquisition activity impacting the existing Peer Group companies.

COMPENSATION-RELATED MATTERS/COMPENSATION DISCUSSION AND ANALYSIS

Further, in our review of the Peer Group data, we also consider the practices of the 10-company sub-group of peers viewed as having businesses and drug discovery and development cultures that are most similar to Regeneron’s, with similarly-sized employee bases (marked with an asterisk in the table above and referred to as “Biotech R&D Peers”).

In making the compensation decisions in December 2019, we used data from publicly filed proxy statements of the companies in the Peer Group (as compiled by the Compensation Committee’s compensation consultant) to review each component of compensation of our NEOs against their peers in the Peer Group as well as their total annual compensation in relation to the Peer Group, while taking into account various factors such as the executive’s performance, past compensation history, experience, and their role in the Company’s success. We use Peer Group data as a point of reference for measurement, but Peer Group data do not represent the only factor considered and there is no targeted pay level percentile. The Compensation Committee retains discretion in determining the nature and extent of the use of Peer Group data.

RISK ASSESSMENT

We believe that the Company’s programs balance risk and potential reward in a manner that is appropriate to the Company’s circumstances and in the best interests of the Company’s shareholders over the long term. We also believe that the Company’s compensation and benefits programs do not create risks that are reasonably likely to have a material adverse effect on the Company. We regularly review the Company’s compensation and benefits programs, including its executive compensation program and its incentive-based compensation programs (such as sales incentive plans). The Company’s compensation and governance-related policies are further enhanced by our stock ownership guidelines applicable to our senior officers and our policy regarding recoupment or reduction (clawback) of incentive compensation of our officers and other specified employees for compliance violations; as well as a policy against hedging and pledging of our securities by our directors and employees, including the Chief Executive Officer.

AllNEOs. We also have a policy against including excise tax gross-up provisions with respect to payments contingent upon a change in control of Regeneron in contracts, compensatory plans, or other arrangements with the Named Officers are eligibleCompany’s executive officers, including the NEOs (other than the existing employment agreement with our CEO or any amendments thereto, which we expressly exempted). These policies demonstrate Regeneron’s continued commitment to receive financial and tax planning assistance, which are taxable benefitsrobust corporate governance and are meant to savereduce compensation-related risks and ensure greater alignment of the executives timeinterests of our employees, including the NEOs, and those of the Company and our shareholders.

TAX IMPLICATIONS

We take tax considerations into account in making our compensation-related assessments and decisions.

Prior to the enactment of the Tax Cuts and Jobs Act in December 2017, Section 162(m) of the Internal Revenue Code generally limited the deductibility for federal income tax purposes of compensation in any year paid to the CEO and the other NEOs (other than the Chief Financial Officer) (the “covered employees”) to the extent such compensation exceeded $1 million, subject to certain exceptions. “Performance-based” compensation, as defined under Section 162(m) of the Internal Revenue Code, was exempt from such deduction limitation if specified requirements set forth in the Internal Revenue Code and applicable Treasury regulations were met. The Regeneron Pharmaceuticals, Inc. Cash Incentive Bonus Plan and the Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan, each adopted prior to the enactment of the Tax Cuts and Jobs Act, allow (but do not require) awards thereunder to be subject to the attainment of performance goals in order to focus on business mattersqualify for this performance-based compensation exception.

Under the Tax Cuts and Jobs Act, which became effective for us commencing with our 2018 fiscal year, the exception under Section 162(m) for performance-based compensation is no longer generally available, subject to transition relief for certain grandfathered arrangements in effect as well asof November 2, 2017. Further, the definition of covered employees has been expanded to recognize that their tax situations are affected by their employment at Regeneron. Similar to other employees, the Named Officers may participate in company-wide health, disability, life insurance, and other benefit plans, as well asinclude our 401(k) Savings Plan. All employees who participate in our 401(k) Savings Plan are eligible to receive certain matching contributions.CFO. In each plan year, we contribute to each participant's account a matching contribution (in the form of sharesaddition, once one of our common stock) equalNEOs is considered a covered employee subject to 50%the deduction limitation of Section 162(m), the NEO will remain a specified percentagecovered employee so long as he or she receives compensation from us.

Each of our Named Officers participated in our 401(k) Savings Plan during 2015 and received a matching contribution in the aggregate amount of $10,600 in the form of shares of our common stock. The contribution was paid in February 2016 and is included in the compensation amounts reported for each of our Named Officers in the Summary Compensation Table included in this proxy statement. As with all employees, the number of shares of common stock that each Named Officer received was determined using the average market price per share of our common stock during the 401(k) Savings Plan year, which for 2015 was $498.52.

Schleifer and Yancopoulos (as well as their spouses and dependent children when they accompany them)determining NEOs’ compensation. However, we reserve the right to use as much as practicable, Company-provided aircraft for all business and personal air travel. Starting in 2016, Regeneron will cover the cost of any such personal air travel for upour judgment to $250,000 in incremental cost annually for each of Drs. Schleifer and Yancopoulos. Family members or other guests may accompany our Named Officers and directors during on-demand air business travel, space permitting, so long as they cover any incremental cost related to such guests (other than with respect to the family members of Drs. Schleifer and Yancopoulos as described above). In addition, in limited circumstances personal use of on-demand air travel by our other Named Officers or directors may be permitted if authorized by the Chairman and any incremental cost is paid by the lead passenger. Any required reimbursement or other payment of the incremental cost is made to the extent permitted by applicable Federal Aviation Administration rules.

There was no unreimbursed personal use, or guest use resulting in any incremental cost to us, of Company-provided aircraft in 2015.

The Corporate Governance and Compliance Committee monitors business and any personal or guest on-demand air travel on a periodic basis.

Additional information regarding perquisites and other personal benefits provided to our Named Officers in, or with respect to, 2015 is given in the applicable footnotes to the Summary Compensation Table included in this proxy statement.

Potential Severance Benefits

Outstanding stock option award agreements (as well as outstanding restricted stock award agreements) for all employees (other than Dr. Vagelos, whose stock option awards contain change-of-control provisions consistent with those of non-employee director stock option awards, as described under "Corporate Governance – Compensation of Directors" above) include a "double trigger" provision for the acceleration of vesting of unvested stock options (or restricted stock) upon a termination by the Company without cause or by the employee for good reason within two years following a change in control. Our Chief Executive Officer has an employment agreement that provides for certain severance benefits following termination, including following death or disability, resignation following defined "good reason" events, or termination in connection with a change in control. The other Named Officers are covered by a change in control severance plan, which provides certain benefits to them and other designated officers if they are terminated in connection with a change in control. In addition, in the case of our Chief Scientific Officer, stock option and restricted stock award agreements applicable to his awards granted starting in December 2015 provide that he would have a "good reason" for terminating his employment with Regeneron upon or within two years after the occurrence of a change in control if the employment of our Chief Executive Officer has ended due to our Chief Executive Officer's involuntary termination (as defined in his employment agreement). Information regarding applicableauthorize compensation payments under this employment agreement and change in control severance plan is provided under the heading "Post-Employment Compensation" on page 66.

Except as provided in our employment agreement with our Chief Executive Officer and in our change in control severance plan, our Named Officers will forfeit any unvested time-based stock options or restricted stock upon the termination of their employment for any reason (including disability or retirement) other than death. In the event of the death of an employee, any unvested stock options held by such employee become immediately exercisable, and any shares of restricted stock will become fully vested. For information regarding unvested stock options and shares of restricted stock held by our Named Officers as of December 31, 2015, see "Outstanding Equity Awards at Fiscal Year-End" on page 64. When employees (other than our Chief Executive Officer) retire, they forfeit all unvested time-based stock options and restricted stock. For all stock options granted prior to 2007, an employee (other than our Chief Executive Officer) who retires has up to two years to exercise stock options that are vestednot deductible, such as ofwhen we believe that such payments are necessary to maintain the date of hisflexibility needed to attract talent, promote executive retention, reward performance, or her retirement. Commencing in 2007, we amended our forms of stock option agreementattain other Company objectives, or as required to allow the retired employee the remaining life of the 10-year stock option term to exercise stock options that are vested as of the date of his or her retirement.

The severance benefits provided to our Named Officers are designed to promote stability and continuity of our senior management and are intended to preserve employee morale and productivity and encourage retention in the face of the disruptive impact of an actual, threatened, or rumored change in control of the Company. The severance benefits were established following a review of comparable practices at the Company's peer companies andcomply with the adviceCompany’s contractual commitments.

Post-Employment CompensationPOST-EMPLOYMENT COMPENSATION

As discussed under "Section 4 – Elements of Executivein “Compensation Dashboard—Additional Compensation – Information—Potential Severance Benefits" on page 59,Payments,” our Named OfficersNEOs are entitled to certain severance benefits upon the voluntary or involuntary termination of their employment. We provide additional information regarding the severance benefits available to our Named OfficersNEOs in the tables on pages 67 and 69.set out below in this subsection. For our Chief Executive Officer,CEO, the table shows the amounts payable under his employment agreement upon his involuntary or not-for-cause termination, termination in connection with a corporate change of control, and in the event of his disability or death. For the other Named Officers,NEOs, the table shows their post-termination compensation arrangements under our change in control severance plan upon an involuntary or not-for-cause termination in connection with a corporate change of control.

    Leonard S. Schleifer, M.D., Ph.D., Employment Agreement

We entered into an employment agreement with our Chief Executive Officer,CEO, Dr. Schleifer, effective as of December 20, 2002, providing for his employment with the Company through December 31, 2003 and continuing thereafter on a year-by-year basis. On November 14, 2008, this employment agreement was amended and restated to bring the employment agreement into compliance with Section 409A of the

Internal Revenue Code. Pursuant to this agreement, we agreed that in the event that Dr. Schleifer'sSchleifer’s employment is terminated by us other than for cause (as defined in the agreement) or is terminated by Dr. Schleifer for good reason (as defined in the agreement to include specified acts of constructive termination, together called an "involuntary termination"“involuntary termination”), we will pay Dr. Schleifer an amount equal to 125% of the sum of his base salary plus his average bonuscash incentive paid over the prior three years. This amount will be paid in a lump sumlump-sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for eighteen18 months. Subject to the discussion in the following paragraph, in the event that Dr. Schleifer'sSchleifer’s employment is terminatedterminates for any reason other than for cause, (i) all of his unvested stock options will continue to vest in accordance with the terms of the applicable award grant and he will be entitled to exercise the stock options throughout their original term, which is generally ten years from the date of grant.grant, and (ii) all of his unvested PSUs will remain outstanding, and vesting and forfeiture shall be determined in the manner set forth in the applicable award agreement, without regard to such termination of employment.

Upon an involuntary termination (i.e., a termination by the Company without cause or by Dr. Schleifer for good reason, each as defined in the agreement) within three years after a change of control of the Company or within three months prior to such a change of control, we will pay Dr. Schleifer an amount equal to three times the sum of his annual base salary plus his average bonuscash incentive over the prior three years. This amount will be paid in a lump sumlump-sum severance payment. In addition, we will continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance benefits for thirty-six36 months. Upon such an involuntary termination in

connection with a change of control, Dr. Schleifer'sSchleifer’s outstanding stock options will vest immediately and remain exercisable throughout their original term, which is generally ten years from the date of grant. In addition, pursuant to the terms of his PSU award agreement, any PSUs

that vest upon a change of control (as a result of performance exceeding the relevant TSR goal for the period from the grant date to the date of the change of control) will become deliverable to Dr. Schleifer upon the earlier of (x) the five-year anniversary of the grant date or (y) a termination of Dr. Schleifer’s employment by the Company without cause or by Dr. Schleifer for good reason, in each case within two years after such a change of control. If aggregate severance payments to Dr. Schleifer in connection with a change of control exceed certain thresholds set forth in the Internal Revenue Code, then we will pay him an additional amount to cover any resulting excise tax obligations, unless the excise taxes could be eliminated by reducing Dr. Schleifer'sSchleifer’s cash severance payments and benefits under the agreement by less than ten

percent,10%, in which case such benefits and payments will be reduced accordingly.

The following table reflects the potential payments to our Chief Executive OfficerCEO under his employment agreement upon hisassuming a termination effective December 31, 2015,2019 under different scenarios including(including following a change of control,control), as well as upon death or disability. The information in the table below is based on the assumptions set forth in the footnotes to the table; actual values and amounts may differ from those presented below.

1For purposes of these calculations, (i) we used Dr. Schleifer’s 2019 base salary and the annual cash incentives paid to Dr. Schleifer for performance in 2016, 2017, and 2018, respectively; (ii) we assumed that Dr. Schleifer received his annual cash incentive that was earned in 2019 and paid in 2020 (described in the Summary Compensation Table above); (iii) we took into consideration, for purposes of determining whether Dr. Schleifer was entitled to receive a gross-up payment under the terms of his employment agreement, the fact that Dr. Schleifer’s stock options continue to vest according to their original vesting schedule following a voluntary or involuntary termination (other than in connection with a change of control); (iv) we assumed a 5.6% annual increase in medical premiums, 4% annual increase in dental premiums, and no increase in annual disability or life insurance premiums; (v) we assumed that the medical and dental insurance benefits received in 2020, 2021, and 2022 would be taxable and that Dr. Schleifer would be eligible for a tax gross-up for these benefits under the terms of his employment agreement; (vi) although Dr. Schleifer’s employment agreement provides for restrictive covenants, including a six-month non-compete obligation, no specific value has been ascribed to these covenants solely for purposes of this calculation; and (vii) although certain payments to Dr. Schleifer would be subject to potential delays upon separation of service under Section 409A of the Internal Revenue Code, we did not attempt to determine which, if any, payments would be delayed.
2Equal to three times the sum of (a) Dr. Schleifer’s 2019 base salary and (b) the average annual cash incentive paid to Dr. Schleifer for performance in the three completed years prior to the termination date. For purposes of this calculation, we used Dr. Schleifer’s annual cash incentives for performance in 2016, 2017, and 2018.
3Equal to the estimated cost of providing Dr. Schleifer and his dependents medical, dental, and life insurance benefits for 36 months.
4We maintain $1 million of term life insurance covering Dr. Schleifer payable to his designated beneficiary.
5Equal to the aggregate amount of the differences between the exercise prices of Dr. Schleifer’s accelerated stock options and the closing sales price per share of the Company’s common stock on the Nasdaq Global Select Market on December 31, 2019, the last business day of 2019, of $375.48. None of Dr. Schleifer’s outstanding PSUs would have been earned had a vesting determination been made on December 31, 2019 in respect of performance for the period from the date of grant to December 31, 2019.
6Under Dr. Schleifer’s employment agreement, if payments due in connection with a change of control are subject to excise taxes under Section 280G of the Internal Revenue Code, we will cut back the payments if the excise tax can be eliminated by reducing his cash severance payments and benefits by less than 10%. Otherwise, we will pay him an additional “gross up” amount so that his after-tax benefits are the same as though no excise tax had been applied. We have determined that Dr. Schleifer would not have been subject to excise taxes if he had been terminated on December 31, 2019 as a result of a change of control.
7Equal to 1.25 times the sum of (a) Dr. Schleifer’s 2019 base salary and (b) the average annual cash incentive paid to Dr. Schleifer for performance in the three completed years prior to the termination date. For purposes of this calculation, we used Dr. Schleifer’s year-end cash incentive awards for performance in 2016, 2017, and 2018.
8Equal to the estimated cost of providing Dr. Schleifer and his dependents medical, dental, and life insurance benefits for 18 months.
9Equal to the estimated cost of providing Dr. Schleifer’s dependents medical and dental benefits for 18 months.
10As discussed in “Compensation Dashboard—Additional Compensation Information—Potential Severance Payments,” unvested stock options held by any employee (including Dr. Schleifer) become immediately exercisable upon his or her death. In addition, any PSUs held by Dr. Schleifer will remain outstanding upon his death, and any vesting or forfeiture of such PSUs will be determined following the completion of the applicable performance period as it otherwise would have been determined if he remained employed by the Company for the duration of such performance period.
11Represents 35% of Dr. Schleifer’s 2019 salary over a period of 18 months. We have assumed long-term disability coverage exists pursuant to Dr. Schleifer’s employment agreement for the remaining 65% of Dr. Schleifer’s salary.

3

6
Under Dr. Schleifer's employment agreement, if payments due in connection with a change of control are subject to excise taxes under Section 280G of the Internal Revenue Code, we will cut back the payments if the excise tax can be eliminated by reducing his cash severance payments and benefits by less than ten percent.

    Change in Control Severance Plan

Each of the Named Officers,NEOs, other than our Chief Executive Officer,CEO, participates in our change in control severance plan that was adopted by the board of directors on January 20, 2006. The purposes of the plan are (i) to help us retain key employees, (ii) to help maintain the focus of such employees on our business and to mitigate the distractions caused by the possibility that we may be the target of an acquisition, and (iii) to provide certain benefits to such employees in the event their employment is terminated (or constructively terminated) after, or in contemplation of, a change in control. On November 14, 2008, the change in control severance plan was amended and restated to bring it into compliance with Section 409A of the Internal Revenue Code.

Under the plan, each participant is entitled to receive a cash severance payment in an amount equal to one, or, in designated cases, including with respect to the Named OfficersNEOs other than Dr. Schleifer, two times the sum of the participant'sparticipant’s annual base salary and his or her average annual bonuscash incentive over the prior three years if, within two years after or 180 days before a change in control, either the participant resigns his or her employment for Good Reason (as defined in the plan) or the participant'sparticipant’s employment is terminated by the Company for any reason other than Cause (as defined in the plan). This amount will be paid in a lump sumlump-sum severance payment. A participant so terminated is also entitled to receive a pro rata bonuspro-rata cash incentive for the year in which he or she is terminated based on the portion of the year the participant was employed by us. In addition, for either one or two years, as the case may be, plan participants will receive continuation of health care coverage and welfare benefits provided by us, to the extent permitted by our benefit plans, at a cost no greater than what the participant'sparticipant’s cost would have been if he or she had continued his or her employment with the Company.

In the event that a plan participant resigns his or her employment for Good Reason (which generally conforms to the definition in Section 409A), or the participant'sparticipant’s employment is terminated by the Company for any reason other than Cause, in either case within two years after or 180 days before a change in control, then the participant'sparticipant’s stock options and other equity awards granted under our long-term incentive plans that would have vested prior to or upon the change in control will become vested on the change in control date, and the exercise period of such equity awards, and other equity awards held by the participant that otherwise would have expired, will be extended to the later of (i) thirty30 days following the first date after a change in control in which the shares underlying the equity award may be traded, and (ii) the permitted exercise date in the plan or grant assuming the change in control happened immediately prior to the participant'sparticipant’s termination. However, in no event will any stock option or other equity award be extended (i) beyond the expiration date of the grant, or (ii) such that the grant will be subject to the additional tax under Section 409A of the Internal Revenue Code.

In the event that a participant would become subject to a "golden parachute"“golden parachute” excise tax under Section 4999 of the Internal Revenue Code as a result of severance benefits and payments, the severance benefits and payments owed to the participant shall be reduced to an amount one dollar less than the amount that would subject the participant to the excise tax, unless the total severance benefits/payments net of the excise taxes are greater than the amount that the participant would receive following any such reduction.

ADDITIONAL COMPENSATION INFORMATION

ANNUAL CASH INCENTIVES

In 2016, we adopted our Cash Incentive Bonus Plan for purposes of allowing our annual cash incentives to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code and permitting us to deduct cash incentive compensation that might otherwise not be deductible by reason of Section 162(m) (as then in effect). Although the Tax Cuts and Jobs Act eliminated the performance-based compensation exception for compensation paid in 2018 and beyond (as discussed under “Our Compensation Processes—Tax Implications” above), we have continued to use the Cash Incentive Bonus Plan for annual cash incentives for the reasons discussed under “Compensation Discussion and Analysis—Our Compensation Philosophy and Objectives” above. For 2019 annual cash incentives for the NEOs, we set up a cash incentive pool and a R&D-related performance goal consisting of (i) the submission of one or more Investigational New Drug Applications, Biologics License Applications, or supplemental Biologics License Applications with the FDA (or its equivalent outside the United States) or (ii) the approval of any regulatory filing of the type described in clause (i) by the FDA or the applicable regulatory authority outside the United States. The Compensation Committee determined that Regeneron’s performance in 2019 exceeded the established goal, thus enabling the funding of the cash incentive pool. The Compensation Committee then exercised “negative discretion” (as permitted under the Plan) to reduce the annual cash incentive amounts otherwise payable to the NEOs according to the cash incentive pool formula. This negative discretion was exercised based on the Compensation Committee’s analysis of all of the relevant facts and circumstances, including the NEOs respective target cash incentive amounts and individual performance in 2019.

The targets for the 2019 annual cash incentives for the NEOs were set as percentages of their respective base salaries as follows: Dr. Schleifer—120%; Dr. Yancopoulos—120%; Mr. Landry—65%; Mr. Van Plew—65%; and Dr. Murphy—65%.

For 2019, Dr. Schleifer’s target cash compensation was set approximately at the median of the Peer Group. In determining the cash incentive target for Dr. Yancopoulos, the Compensation Committee took into consideration the importance of his scientific leadership as President & CSO and the significant contributions he has made to the success of the Company and, specifically, to the discovery and development of the Company’s commercial products, its pipeline of internally developed product candidates, and its platform technologies. The Compensation Committee determined that there were no meaningful comparative data for Dr. Yancopoulos relating to similarly situated executives and that his base salary and cash incentive for 2019 would be set at 85% of Dr. Schleifer’s. In determining the cash incentive targets for 2019 for Mr. Landry, Mr. Van Plew, and Dr. Murphy, the Compensation Committee took into consideration the compensation of similarly situated executive officers at companies in the Peer Group.

The cash incentives were determined through the use of both an individual and a Company performance component with a possible range of 0 to 1.5 for the personal performance multiplier and a possible range of 0 to 2.0 for the Company performance multiplier, depending upon performance during the year. Both the personal performance multiplier and the Company performance multiplier were determined by the Compensation Committee for each NEO based on the Committee’s assessment of the Company’s performance relative to the general corporate goals described below and, in the case of each of Mr. Landry, Mr. Van Plew, and Dr. Murphy, the NEO’s personal performance during the year.

The pipeline-related and other factors that contributed most to the Compensation Committee’s determination of the Company performance multiplier (which was set at 1.85 for 2019) are summarized in the subsection “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Cash Incentives.”

With respect to 2019, the Compensation Committee approved a personal performance multiplier of 1.5 for each of Mr. Landry, Mr. Van Plew, and Dr. Murphy. The personal performance component accounted for 40% of these NEOs’ cash incentives. The Company component was based on a Company performance multiplier that was determined based on the Company’s overall corporate performance (as described above) against 2019 goals that were approved by the board of directors in January 2019. This Company performance component accounted for 60% of the cash

COMPENSATION-RELATED MATTERS/COMPENSATION DASHBOARD

incentives awarded to Mr. Landry, Mr. Van Plew, and Dr. Murphy. In the case of Drs. Schleifer and Yancopoulos, the Compensation Committee focused exclusively on overall Company performance in 2019 (as described above) when determining their cash incentives and did not utilize a personal performance multiplier.

In determining the personal performance multiplier for Mr. Landry, the Compensation Committee gave special consideration to Mr. Landry’s leadership of and accomplishments in the Company’s accounting, finance, and tax functions and across his other responsibilities, including his leadership of the information technology and real estate & facilities management organizations. In the case of Mr. Landry (who joinedVan Plew, the Compensation Committee focused primarily on Mr. Van Plew’s leadership of and accomplishments in the Company’s Industrial Operations and Product Supply organization, including with respect to expanded manufacturing capacities, preparations for new product launches, successful technology transfer of commercial manufacturing of certain Company products between Regeneron’s Rensselaer, New York and Raheen, Ireland facilities, and successful completion of all regulatory audits concerning the Company’s manufacturing practices in September 2013),2019. In the case of Dr. Murphy, the Compensation Committee considered the progress and continued expansion of the Company’s preclinical and clinical development pipeline, as summarized in the subsection “Compensation Discussion and Analysis—Components of Executive Pay: What We Pay and Why We Pay It—Annual Cash Incentives.”

PERQUISITES AND PERSONAL BENEFITS

All employees who participate in our 401(k) Savings Plan, including the NEOs, are eligible to receive certain matching contributions. In each plan year, we averaged his 2013 and 2014 annual bonus amountscontribute to each participant’s account a matching contribution (in the form of $0 and $405,000, respectively, and took into accountshares of our common stock) equal to 50% of a specified percentage of the participant’s compensation that he did not receive a bonus in respect of his performance in 2013.

The contributions were paid quarterly (with the contribution in respect of the fourth quarter of 2019 paid in February 2020) and are included in the compensation amounts reported for each Named Officer's accelerated "in-the-money"of our NEOs in the Summary Compensation Table included in this proxy statement. As with all employees, the number of shares of common stock options andthat each NEO received on a quarterly basis was determined using the closing salesaverage market price per share of the Company'sour common stock during the applicable quarter.

To achieve increased efficiencies and a more secure traveling environment, the Company provides air transportation for certain executive and director travel in accordance with guidelines approved by our board of directors. Based on the NASDAQ Global Select Marketrecommendation of an independent, third-party security study, the guidelines and our security policy require Drs. Schleifer and Yancopoulos (as well as their spouses and children when they accompany them) to use, as much as practicable, Company-provided aircraft for all business and personal air travel. Regeneron covers the cost of any such personal air travel for up to $250,000 in incremental cost (as described below) annually for each of Drs. Schleifer and Yancopoulos. Family members or other guests may accompany our NEOs and directors during Company-provided air business travel, space permitting, so long as they cover any incremental cost related to such guests (other than with respect to the family members of Drs. Schleifer and Yancopoulos as described above). In addition, in limited circumstances personal use of Company-provided air travel by our other NEOs or directors may be permitted if authorized by the Chairman and any incremental cost is paid by the lead passenger. Any required reimbursement or other payment of the incremental cost is made to the extent permitted by applicable Federal Aviation Administration rules.

We determine the incremental cost of any Company-provided personal or guest air travel based on December 31, 2015the direct variable operating cost. Items included in the calculation include (as applicable) fuel costs; landing, non-home-base hangar or aircraft parking, and ground handling fees; in-flight catering; travel, lodging, and other expenses for flight crew; and other trip-related variable cost, including the use of $542.87. our fractional jet interests. Because Company-provided air transportation is used primarily for business travel, incremental costs exclude fixed costs that generally do not change based on usage, such as (as applicable) flight crew salaries; aircraft purchase or lease costs; depreciation; insurance costs; certain maintenance fees based on minimum usage; and home-base hangar costs. When the aircraft is already flying to a destination for business purposes, only the direct variable costs associated with the guest (for example, catering), if any, are included in determining the aggregate incremental cost to Regeneron. If any aircraft flies empty before picking up or after dropping off a passenger for personal reasons, this “deadhead” segment would be included in the aggregate incremental cost based on the methodology described above. The amount of disallowed corporate tax deductions attributable to Company-provided personal and guest air travel is not included in the NEO incremental cost calculation.

2020 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING   /   95

COMPENSATION-RELATED MATTERS/COMPENSATION DASHBOARD

The security policy also covers secure car transportation and on-site residential security at the primary residence for each of Drs. Schleifer and Yancopoulos. We calculate the incremental costs of the secure car transportation and on-site residential security services provided by Regeneron as the average fuel cost per mile times total miles traveled in connection with such services (if applicable) plus the contractor rate (if any) and salary, taxes, and benefits of drivers attributed to such services based on the number of personal hours expended for such services. Fixed lease costs and routine maintenance that would have been incurred in any event are not included.

Amounts associated with personal or guest Company-provided air and secure car transportation/security services are imputed as income to the NEOs to the extent required by applicable tax regulations. The NEOs do not receive a tax gross-up from us to cover their personal income tax obligations in respect of any such imputed income.

The amounts also disclosed in the “All other compensation” column of the Summary Compensation Table relating to personal and guest use of Company-provided air and secure car transportation/security services in accordance with our security policy attributable to Drs. Schleifer and Yancopoulos are based on the incremental cost resulting from such transportation/services as described above.

The Corporate Governance and Compliance Committee monitors business and any personal or guest Company-provided air travel on a periodic basis.

Additional information regarding perquisites and other personal benefits provided to our NEOs in, or with respect to, 2019 is given in the applicable footnotes to the Summary Compensation Table included in this proxy statement.

POTENTIAL SEVERANCE PAYMENTS

Except for Dr. Vagelos, outstanding stock option award agreements for all employees, as well as outstanding RSA and PSU award agreements,11include a “double trigger” provision for the acceleration of vesting of unvested stock options, RSAs, or PSUs upon a termination by the Company without cause or by the employee for good reason within two years following a change in control. Dr. Vagelos’s stock option and PSU awards contain change-of-control provisions consistent with those applicable to the non-employee director equity awards, as described under “Corporate Governance – Compensation of Directors” above.

Our CEO has an employment agreement that provides for certain severance benefits following termination, including following death or disability, resignation following defined “good reason” events, or termination in connection with a change in control. The other NEOs are covered by a change in control severance plan, which provides certain benefits to them and other designated officers if they are terminated in connection with a change in control. In addition, in the case of our CSO, stock option, RSA, and PSU award agreements applicable to his awards granted since December 2015 provide that he would have a “good reason” for terminating his employment with Regeneron upon or within two years after the occurrence of a change in control if the employment of our CEO has ended due to our CEO’s involuntary termination (as defined in the CEO’s employment agreement). Information regarding applicable payments under this employment agreement and change in control severance plan is provided in the subsection “2019 Compensation Tables—Post-Employment Compensation.”

Our NEOs will forfeit any unvested time-based stock options or RSAs upon the termination of their employment for any reason (including disability or retirement) other than death, except as provided in our employment agreement with our CEO, in our change in control severance plan, and in certain stock option agreements with our CSO. In the event of the death of an employee, any unvested stock options held by such employee become immediately exercisable, and any shares subject to RSAs/RSUs will become fully vested. In the case of PSU awards to our CEO and CSO (as well as Dr. Vagelos, as described under “Corporate Governance – Compensation of Directors” above), upon a termination of employment due to death (or retirement when “retirement eligible,” as discussed below), the PSU award will remain outstanding, and any vesting of the PSUs will be determined following the completion of the applicable performance period. For information regarding the value of accelerated stock options, RSAs, and PSUs held by our CEO and other NEOs (as applicable) as of December 31, 20152019, see the subsection “2019 Compensation Tables—Post-Employment Compensation” under “Value of Accelerated Stock Options/PSUs” in the table entitled “Potential Severance Payments

11In the case of PSUs, if any PSUs vest upon a change of control (as a result of performance exceeding the relevant TSR goal for the period from the date of grant to the date of the change of control), the shares earned will be delivered upon the earlier of (a) a termination by the Company without cause or by the employee for good reason within two years following the change in control and (b) the fifth year anniversary of the date of grant.

When employees (other than our CEO and, with respect to stock option awards commencing in December 2018 and PSU awards, our CSO and Dr. Vagelos) retire, they forfeit all unvested restricted stock.

time-based stock options, RSAs, and PSUs. An employee considered “retirement eligible” upon separation under our employee policies as in effect from time to time has the remaining life of the 10-year stock option term to exercise stock options that are vested as of the date of his or her retirement. In addition, the award agreements with our CSO and Dr. Vagelos relating to their 2018 and 2019 stock option awards and 2019 PSU awards provide that their respective awards will continue to vest in accordance with the terms of the applicable award agreement so long as they are “retirement eligible” upon separation.

The severance benefits provided to our NEOs are designed to promote stability and continuity of our senior management and are intended to preserve employee morale and productivity and encourage retention in the face of the disruptive impact of an actual, threatened, or rumored change in control of the Company. The severance plan,benefits were established following a review of comparable practices at the Company’s peer companies and with the advice of the Compensation Committee’s consultant.

We have no pension, deferred compensation, or retirement plans applicable to our NEOs, other than our 401(k) Savings Plan described above.

PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to disclose the median of the annual total compensation of our employees (excluding our principal executive officer), the annual total compensation of our principal executive officer, Dr. Schleifer, and the ratio of these two amounts.

We have determined the total amount for Mr. Landry has not been "cut back"compensation of our median employee (based on the 2019 annual total compensation of our employees, excluding Dr. Schleifer) to be $139,055. The total 2019 compensation of Dr. Schleifer, as he would be in a more favorable net after-tax position without any such reduction. None of the other Named Officers listed in the table above would have been expected to receive severance payments in excess of his applicable "golden parachute" safe harbor amount.

5
For purposes of these calculations, (i) we used base salaries as of December 31, 2015 and annual bonuses paid to the Named Officers (other than Mr. Landry) for performance in 2012, 2013, and 2014, respectively; in the case of Mr. Landry (who joined the Company in September 2013), we averaged his 2013 and 2014 annual bonus amounts of $0 and $405,000, respectively, and took into account that he did not receive a bonus in respect of his performance in 2013; (ii) we assumed that each Named Officer received his annual bonus that was earned in 2015 and paid in 2016 (describedreported in the Summary Compensation Table above, was $21,455,117. Accordingly, the ratio of the 2019 annual total compensation of Dr. Schleifer to the median of the 2019 annual total compensation of our employees was approximately 154 to 1.

Consistent with our process for identifying the median employee for 2017 and 2018, for 2019 we identified the median employee as of December 31, 2019 by (i) aggregating for each applicable employee (a) annual base salary for salaried employees (or wages plus overtime, based on page 61); (iii) we took into consideration,annual work schedule, for permanent hourly employees), (b) the annual cash incentive, and (c) the grant date fair value of any equity awards granted during 2019, and (ii) ranking this compensation measure from lowest to highest. This calculation was performed for all employees, excluding Dr. Schleifer, whether employed on a full-time, part-time, or seasonal basis. For purposes of determining whether each Named Officer was subjectidentifying the median employee, we converted amounts paid in foreign currencies to U.S. dollars based on the applicable 2019 average exchange rate.

We believe that the pay ratio reported above is a reduction underreasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the termsmethodology described above. Because the SEC rules for identifying the median compensated 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 employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

PROPOSAL 03: APPROVAL OF SECOND AMENDMENT AND RESTATEMENT OF LONG-TERM INCENTIVE PLAN

INTRODUCTION

It would be difficult to overstate the importance of this proposal to the Company and its core strategy. Using equity awards to motivate, reward, and retain all of our employees has been a key part of Regeneron’s strategy and compensation philosophy since the Company’s inception. We firmly believe that this compensation model, including the use of equity awards as a primary long-term employee incentive, directly supports Regeneron’s core strategy to create and advance a high-quality, internally developed product pipeline and has helped us establish a culture where employees focus on our mission and drug discovery and development. A primary underpinning of our pay philosophy is to award equity-based pay toall employees, not just senior executives, to ensure that when we deliver for patients and for shareholders, everyone shares in the potential upside growth. In each of the last five years, approximately 90% of the employee equity grants (both based on grant date fair value and number of underlying shares) were awarded to our employees other than our NEOs12. We believe that our broad-based equity program, which ensures that all employees can share in our future potential in the same way as executives, represents one of our competitive advantages.

Key Takeaways
1Our equity compensation program supports all of our employees, not just our NEOs, with approximately 90% of recent annual equity grants awarded to employees other than our NEOs.
2We granted PSUs to our CEO and CSO as a component of their 2019 annual equity awards. This and other carefully calibrated changes to our compensation program were based on investor feedback.
3Our 2019 burn rate was at the lowest level in the last seven years due to specific steps we took to manage dilution from equity compensation.
4We are asking our shareholders to approve the same number of shares for equity grants that we requested previously and are committed to ensuring that shares available under our long-term incentive plan will be sufficient for at least three years.
5Our compensation model underpins our strategy of creating and advancing a high-quality, internally developed product pipeline, which delivered six important medicines and eight additional key indications for these products in the past decade.

A breakdown of employee equity grants in 2019 (when approximately 92% of such grants were awarded to non-NEOs) is provided below.

2019 Employee Equity Grants

We will not be able to execute our strategy without shareholder support of our equity compensation plans and this proposal. We are making this request after a rigorous assessment of our strategy and goals and after taking affirmative steps to manage our burn rate and dilution without compromising our all-employee equity compensation model. These steps include a significant reduction in the number of shares underlying the annual equity awards of our eligible employees, including our CEO, by nearly 60% between 2012 and 2019; and the addition of full-value awards (RSAs and RSUs) to the annual long-term incentive mix for our employees and thereby reducing the number of shares required for these awards. The results of these efforts are illustrated by the chart below.13

12See the list of our “Named Executive Officers” or “NEOs” in the “Compensation Discussion and Analysis” section of this proxy statement.

PROPOSAL 03: APPROVAL OF SECOND AMENDMENT AND RESTATEMENT OF LONG-TERM INCENTIVE PLAN

Regeneron Stock Utilization vs. Headcount*

*Burn rate calculated by dividing the number of shares subject to equity awards (stock options, RSAs, and RSUs) granted during the year by the basic weighted-average number of shares of common stock and Class A stock outstanding during the year. PSUs are to be reflected in the burn rate calculation for the year in which they are earned and, therefore, do not impact the burn rate shown in the chart. Headcount numbers based on the number of employees as of December 31 of the applicable year.

In the last decade, we sought shareholder approval of additional shares for our long-term incentive plans three times: 2011, 2014, and 2017. Each time, we requested the same number of shares – 12 million – and lived up to our commitment not to seek additional shares earlier than three years following approval. We have been able to keep the same size of share requests while maintaining our all-employee equity compensation model and increasing the number of our employees to support our growth (by almost 700% in the last 10 years) because we took the steps to manage our burn rate and dilution discussed above. Once again, we are asking shareholders to approve 12 million additional shares for equity grants and are committed to ensuring that these additional shares (together with the shares currently available under the Current Plan or that may otherwise become available under the New Plan (each as defined below)) will satisfy the Company’s compensation and recruiting needs for no less than three years.

Our pay philosophy and equity compensation strategy are discussed further in the CD&A section of this proxy statement.

We appreciate your support of this important proposal.

SUMMARY OF PROPOSAL AND KEY CHANGES

We currently use one equity incentive plan—the Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan (referred to in this subsection as the "Plan"(the “Current Plan”) is the only plan currently used by the Company to grant equity awards. It has beenawards to our directors, executive officers, and other employees. The Current Plan was approved by our shareholders in 2017; it amended and restated the equity incentive plan that was approved by our shareholders in 2014. On April 3, 2020, the board of directors, upon the recommendation of the Compensation Committee (made following the Committee’s consultation with its independent compensation consultant), and subject to shareholder approval, adopted the Second Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan in the form attached as Appendix B to this proxy statement, which amends and restates the Current Plan (the “New Plan”). Among other things, the New Plan:

increases the number of shares of our common stock available for issuance thereunder by 12 million;
extends the period during which awards can be granted to 2030; and
incorporates new annual limits on the equity awards to our non-employee directors and the current Chairman of the Board as required by the Settlement (as defined and described below).

CORPORATE GOVERNANCE ASPECTS OF THE SECOND AMENDED AND RESTATED REGENERON PHARMACEUTICALS, INC. 2014 LONG-TERM INCENTIVE PLAN

Similar to the Current Plan, the New Plan was designed to include a number of provisions that promote best practices by reinforcing the alignment

between equity compensation arrangements for eligible employees and non-employee directors onand the one hand, and shareholders' interests on the other hand. Theseof shareholders. The provisions that promote such best practices include:


Provision





Description

No Discounted StockOptions or StockAppreciation RightsStock options and stock appreciation rights are not granted with an exercise or base price less than the fair market value of common stock (as defined in the New Plan) on the date of grant.
No Stock Option orStock Appreciation RightRe-pricing or ExchangeExcept for equitable adjustments in connection with specific corporate transactions (such as stock splits, recapitalizations, reorganizations, mergers, consolidations, and similar transactions), the New Plan does not permit a decrease in the exercise price or base price of a stock option or stock appreciation right granted under the New Plan through settlement, cancellation, forfeiture, exchange, surrender, or otherwise below the fair market value of common stock (as defined in the New Plan) on the date of grant.
Minimum Vesting RequirementsRecoupment (Clawback)PolicyIf the vesting condition for any equity award (other than an option or a stock appreciation right) made to an employee is based solely upon continued employment, the regular vesting may not be more favorable to the employee than in equal annual increments over 36 months.

If the vesting condition for any equity award (other than an option or a stock appreciation right) made to an employee is based upon the attainment of specified performance measures, the regular performance vesting period may not be less than one year.

The Compensation Committee's discretion to deviate from the minimum vesting requirements described above is limited to accelerated vesting upon a change of control or upon a termination of the employee's employment and with respect to grants not in excess of 1,000,000 shares in the aggregate under the Plan.

Recoupment PolicyAwards granted to our officers and other specified employees under the New Plan are subject to recoupment or reduction in accordance with the terms of our policy regarding recoupment or reduction of incentive compensation.compensation (sometimes referred to as our “clawback policy”).
Independent AdministrationThe New Plan is administered by the Compensation Committee, which is intended to be comprised solely of non-employee directors each of whom meets the additional independence criteria applicable to compensation committee members under the listing standards of The NASDAQ Stock Market LLC and qualifies as a "Non-Employee Director"“Non-Employee Director” pursuant to Rule 16b-3 under the Exchange Act, and meets the requirements for an "outside director" within the meaning of Section 162(m) of the Internal Revenue Code.Act.
No "Evergreen"“Evergreen” ProvisionThe New Plan does not contain an "evergreen"“evergreen” feature pursuant to which the shares authorized for issuance thereunder can be automatically replenished.
No Tax Gross-upsThe New Plan does not provide for any tax gross-ups.

KEY EQUITY METRICS

The following table summarizes some key metrics relating to the equity component of our compensation program. When evaluating the information below, it is important to keep in mind the 50% increase in the number of our employees from 2017 to 2019 and our all-employee equity award strategy encompassing initial equity grants to all new hires as well as a comprehensive annual equity program covering all levels of employees:

ExecutiveMATERIAL TERMS OF THE NEW PLAN SUBMITTED FOR SHAREHOLDER APPROVAL

The following description of the material terms of the New Plan is qualified in its entirety by the terms of the plan document, which is attached as Appendix B to this proxy statement.

Available Shares.As of April 14, 2020, the record date for this meeting, there were 10,150,052 shares of common stock remaining available for issuance under the Current Plan. Utilizing management’s projections, which are based on past practices and projected headcount, the Compensation Committee has determined that the 12 million shares newly authorized under New Plan being submitted for shareholder approval (along with the remaining 10,150,052 shares authorized under the Current Plan) should satisfy the Company’s equity compensation needs for at least the next three years. If the New Plan is not approved by shareholders, to achieve our equity compensation objectives we will only be able to utilize the remaining 10,150,052 shares of common stock (as of the record date for this meeting) available under the Current Plan (plus any shares subject to awards which are returned to the plan upon the expiration, forfeiture, surrender, exchange, cancellation, or termination of previously granted awards). We believe that the current share pool would be insufficient to satisfy our expected recruiting and compensation needs. If the New Plan is approved by shareholders, an aggregate of 22,150,052 shares will be available for grants under the New Plan. Shares of common stock underlying or issued pursuant to equity awards previously granted under the Current Plan, the Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan (the “2014 Plan”), or the Regeneron Pharmaceuticals, Inc. Second Amended and Restated 2000 Long-Term Incentive Plan (the “2000 Plan”) that would otherwise have again become available under the Current Plan, the 2014 Plan, or the 2000 Plan upon the expiration, forfeiture, surrender, exchange, cancellation, or termination of such previously granted awards, in whole or in part, for any reason, including the surrender of shares to pay the exercise price or satisfy withholding tax obligations in connection with the grant, exercise, or vesting of all or part of an award will be added to the pool of shares available for grant under the New Plan. As of the record date for this meeting, there were 26,047,513 shares subject to outstanding awards (stock options, RSAs, RSUs, and PSUs) previously issued under the Current Plan, the 2014 Plan, and the 2000 Plan. All of the shares reserved and available for issuance under the New Plan, the various limits set forth in the New Plan, and the awards made thereunder will generally be subject to equitable adjustment upon the occurrence of any stock dividend or other distribution, recapitalization, stock split, subdivision, reorganization, merger, consolidation, combination, repurchase, or share exchange, or other similar corporate transaction or event. Shares issued pursuant to awards that are assumed by us in corporate transactions will not count against the shares available under the New Plan.

Plan Term.The term of the New Plan runs through April 3, 2030 (although awards granted prior to such date may continue in effect beyond that date in accordance with their respective terms).

Administration.The New Plan is to be administered by the Compensation Committee of the board of directors. Each member of the Compensation Committee is intended to be a “Non-Employee Director” (within the meaning of Rule 16b-3 under the Exchange Act) and to otherwise qualify as independent to the extent required under applicable law, regulations, and listing standards. The New Plan allows the Compensation Committee to delegate to one or more executive officers of the Company the authority to exercise any of the Compensation Committee’s responsibilities under the New Plan, including the authority to grant awards thereunder (subject to certain limitations set forth in the New Plan).

Amendment; Term.The New Plan may be amended by the board of directors, subject to shareholder approval where necessary, to satisfy certain regulatory or legal requirements. The New Plan will terminate no later than April 3, 2030. However, awards granted before such termination will extend beyond that date in accordance with their terms.

Participants.Awards under the New Plan may be made to employees of the Company, including officers of the Company (whether or not they are directors), and to non-employee directors and consultants. Non-employee directors receive grants subject to the limits described under “Non-Employee Director Awards” below. As of the record date for this meeting, we had 8,095 employees and nine non-employee directors, who would have been eligible to receive awards under the New Plan; as of that date, no consultants would have been eligible to receive awards thereunder.

Awards.There are generally five types of awards that may be granted under the New Plan: Stock Options (including both incentive stock options (referred to as “ISOs”) within the meaning of Section 422 of the Internal Revenue Code

102   /   2020 PROXY STATEMENT AND NOTICE OF ANNUAL SHAREHOLDER MEETING


PROPOSAL 03: APPROVAL OF SECOND AMENDMENT AND RESTATEMENT OF LONG-TERM INCENTIVE PLAN

Equityand nonqualified stock options (referred to as “NQSOs”), which are options that do not qualify as ISOs), Restricted Stock, Phantom Stock (including RSUs and PSUs (each as defined below)), Stock Appreciation Rights, and Stock Bonus awards. In addition, the Compensation Committee in its discretion may make other awards valued in whole or in part by reference to, or otherwise based on, shares of common stock. The maximum number of shares which may be made subject to grants of ISOs during the term of the New Plan Informationis 22,150,052. While the New Plan will permit the issuance of ISOs, the Compensation Committee determined to stop using ISOs in November 2012 and has not authorized any ISOs since then.

Vesting.Awards become exercisable or otherwise vest at the times and upon the conditions that the Compensation Committee may determine, as reflected in the applicable award agreement. The Compensation Committee has the authority to accelerate the vesting and/or exercisability of any outstanding award at such times and under such circumstances as it, in its sole discretion, deems appropriate (for instance, upon a “Change in Control” of the Company, as defined in the New Plan).

Stock Options.Options entitle the holder to purchase shares of common stock during a specified period at the purchase price specified by the Compensation Committee, which may not be less than 100% of the fair market value of the common stock on the day the option is granted (determined as (i) the average of the high and low sales price per share of common stock on the securities exchange or system on which such stock is principally traded on such date or, if such date is not a trading day, on the last preceding date on which there was a sale of such stock on such exchange or system, or (ii) if the shares of common stock are not then listed, or the value of such shares is not otherwise determinable, such value as determined by the Compensation Committee in good faith). Each option granted under the New Plan will be exercisable for a maximum period of 10 years from the date of grant (subject to early termination such as upon a termination of employment), or such lesser period as the Compensation Committee shall determine. Options may be exercised, in whole or in part, by the payment in cash of the full option price of the shares purchased, by tendering shares of common stock with a fair market value equal to the option price of the shares purchased, or by other methods in the discretion of the Compensation Committee. The vesting schedule for options to be granted under the New Plan will be determined by the Compensation Committee. Options that are exercisable as of the date of a participant’s termination of service with the Company may be exercised after such date for the period set forth in the option agreement or as otherwise determined by the Compensation Committee. In the event of the death of a participant, any then outstanding and unexercisable options held by such participant shall become exercisable by the participant’s heirs or legal representatives. Options held by a participant upon termination from the Company’s service for cause shall immediately expire (whether or not then exercisable). Except in connection with specific corporate transactions (such as stock splits, recapitalizations, reorganizations, mergers, consolidations, and similar transactions), the New Plan does not permit a decrease in the exercise price of a stock option granted under the New Plan through settlement, cancellation, forfeiture, exchange, surrender, or otherwise below the fair market value of common stock (as defined in the New Plan and described above) on the date of grant.

Restricted Stock.Restricted stock awards (“RSAs”) consist of a grant of shares of restricted common stock. The Compensation Committee may determine the price, if any, to be paid by a participant for each share of restricted stock subject to an RSA. Unless otherwise provided in the applicable award agreement, an RSA holder may vote, and if the participant remains in the service of the Company until the applicable “Vesting Date” as defined in the New Plan, he or she may generally receive all dividends on, all shares subject to the RSA. However, such holder may not transfer such shares until the applicable Vesting Date. If for any reason before the applicable Vesting Date an RSA holder ceases to be in the employment or service of the Company, unless otherwise provided in the applicable award agreement or determined by the Compensation Committee, the holder shall be required to forfeit to the Company any such RSA together with any dividends paid thereon.

Phantom Stock.A phantom stock award is an award of the right to receive common stock or an amount of cash based on the value of the common stock at a future date, subject to such restrictions, if any, as the Compensation Committee may impose at the date of grant or thereafter, which restrictions may lapse separately or in combination at such times, under such circumstances (including without limitation a specified period of employment or the achievement of certain performance goals), in such installments, or otherwise, as the Compensation Committee may determine. Time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) are each a type of phantom stock award permitted under the New Plan. A phantom stock award settled in cash does not reduce the number of shares of common stock with respect to which awards may be granted under the New Plan.

PROPOSAL 03: APPROVAL OF SECOND AMENDMENT AND RESTATEMENT OF LONG-TERM INCENTIVE PLAN

Stock Appreciation Rights.Stock appreciation rights (“SARs”) entitle the holder to a payment (in cash or shares) equal to the appreciation in the value of our common stock during a specified period above the base price specified by the Compensation Committee, which may not be less than 100% of the fair market value of the common stock (as defined in the New Plan and described above) on the day the SAR is granted. Each SAR granted under the New Plan will be exercisable for a maximum period of 10 years from the date of grant (subject to early termination such as upon a termination of employment), or such lesser period as the Compensation Committee shall determine. The vesting schedule for SARs to be granted under the New Plan will be determined by the Compensation Committee. SARs that are exercisable as of the date of a participant’s termination of service with the Company may be exercised after such date for the period set forth in the SAR agreement or as otherwise determined by the Compensation Committee. Except in connection with specific corporate transactions (such as stock splits, recapitalizations, reorganizations, mergers, consolidations, and similar transactions), the New Plan does not permit a decrease in the base price of a SAR granted under the New Plan through settlement, cancellation, forfeiture, exchange, surrender, or otherwise below the fair market value of common stock on the date of grant.

Stock Bonus.If the Compensation Committee grants a stock bonus award (which an award that is not subject to vesting conditions), a certificate for the shares of common stock consisting of such stock bonus is issued in the name of the participant to whom such grant was made.

Recoupment (Clawback).Awards granted to our officers and other employees under the New Plan will be subject to recoupment or reduction in accordance with the terms of our policy regarding recoupment or reduction of incentive compensation (clawback policy).

Non-Employee Director Awards; Non-Employee Director Compensation Limit.Non-employee directors of the Company are generally eligible to receive awards under the Plan (other than ISOs) under such terms and conditions as the Compensation Committee may determine. During any calendar year, the aggregate number of shares subject to one or more awards granted to a non-employee director in a year may not exceed 12,750 shares, except that during the first calendar year in which a non-employee director serves on the board of directors, such limit will be 34,000 shares;provided, however, that any awards granted to a non-employee director during or prior to 2023 shall be subject to the limitations set forth in the Settlement (as defined and described below). In addition, during any calendar year, the aggregate number of shares subject to one or more awards granted to a non-employee director then serving as chairman of the board of directors in such year may not exceed 25,500 shares, except that during the first calendar year in which a non-employee director serves as chairman of the board of directors, such limit will be 68,000 shares;provided, however, that any awards granted to the current Chairman of the Board, Dr. Vagelos, during or prior to 2022 shall be subject to the limitations set forth in the Settlement. For purposes of applying this limit, an award other than an NQSO or SAR is treated as an award of one and one-half (1.5) shares for each share actually subject to such award, and an award of an NQSO or SAR is treated as an award of one share for each share actually subject to such award.

In December 2018, the Supreme Court of the State of New York, County of New York entered an order and final judgment approving the Stipulation of Compromise and Settlement, dated as of October 5, 2018, by and among the Plaintiffs and the Individual Defendants (each as defined therein) and the Company, as nominal defendant (the “Settlement”) in the shareholder derivative actions entitled Cement Masons Local 780 Pension Fund, et ano. v. Leonard S. Schleifer, et al., Index No. 654453/2015 (N.Y. Co.) (filed December 30, 2015) andPublic Employees’ Retirement System of Mississippi v. Leonard S. Schleifer, et al., Index No. 656813/2017 (N.Y. Co.) (filed November 8, 2017). The terms of the Settlement impose the following limits on equity compensation awarded to the non-employee directors of the Company and the current Chairman of the Board, Dr. Vagelos, respectively:

1The aggregate annual equity compensation per non-employee director shall be limited to $695,000 through 2020, as valued for purposes of the Company’s financial statements; thereafter, through 2023, the aggregate annual equity compensation per non-employee director may be increased by up to 5% annually; and
2The aggregate annual equity compensation for the current Chairman of the Board, Dr. Vagelos, shall be limited to ten times the corresponding annual equity compensation for the non-employee directors through 2022,14 as valued for purposes of the Company’s financial statements.
14Equity awards to the current Chairman of the Board are granted in December annually (along with the equity awards to our full employee base), and each such December grant corresponds to the awards granted to the non-employee directors in January of the following year.

PROPOSAL 03: APPROVAL OF SECOND AMENDMENT AND RESTATEMENT OF LONG-TERM INCENTIVE PLAN

Notwithstanding the foregoing, during the first calendar year in which a non-employee director serves on the board of directors, in addition to the annual equity award compensation set forth in clause (1) above (which shall be prorated for such calendar year based on the date such director is elected to the board), the Settlement permits a non-employee director to be awarded an inducement equity award of up to 5/3rds of (a) the number of shares of common stock underlying the most recent annual equity grant to non-employee directors or (b) the grant date fair value (as valued for purposes of the Company’s financial statements) of such grants. In addition, the Settlement’s limits on compensation awarded to the Company’s directors (including those described above) shall not apply to any successor to Dr. Vagelos to the position of Chairperson of the Board.15

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

Set forth below is a discussion of certain federal income tax consequences with respect to options that may be granted pursuant to the New Plan. The following discussion is a brief summary only, and reference is made to the Internal Revenue Code and the regulations and interpretations issued thereunder for a complete statement of all relevant federal tax consequences. This summary is given as of the date of this proxy statement, is not intended to be exhaustive, and does not describe state, local, or foreign tax consequences of participation in the New Plan. Recipients of awards under the New Plan are advised to consult with their personal tax advisors with regard to all tax consequences arising with respect to their awards.

Incentive Stock Options.In general, no taxable income is realized by a participant upon the grant of an ISO. If shares of common stock are issued to a participant (“Option Shares”) pursuant to the exercise of an ISO granted under the New Plan and the participant does not dispose of the Option Shares within the two-year period after the date of option grant or within one year after the receipt of such Option Shares by the participant (an earlier disposition being referred to as a “disqualifying disposition”), then generally (i) the participant will not realize ordinary income upon exercise and (ii) upon sale of such Option Shares, any amount realized in excess of the exercise price paid for the Option Shares will be taxed to such participant as capital gain (or loss). The amount by which the fair market value of the common stock on the exercise date of an ISO exceeds the purchase price generally will constitute an item which increases the participant’s “alternative minimum taxable income.” If Option Shares acquired upon the exercise of an ISO are disposed of in a disqualifying disposition, the participant generally would include in ordinary income in the year of disposition an amount equal to the excess of the fair market value of the Option Shares at the time of exercise (or, if less, the amount realized on the disposition of the Option Shares) over the exercise price paid for the Option Shares. Subject to certain exceptions, an ISO generally will not be treated as an ISO if it is exercised more than three months (other than by reason of death) following termination of employment. If an ISO is exercised at a time when it no longer qualifies as an ISO, such option will be treated as an NQSO as discussed below. The Company is not entitled to a federal income tax deduction on the grant or exercise of an ISO or on the participant’s disposition of the Option Shares after satisfying the holding period requirements described above. If the holding periods are not satisfied, the Company will be entitled to a deduction in the year the participant disposes of the Option Shares in an amount equal to the ordinary income recognized by the participant. Any additional gain or loss realized will be taxed as a short-term or long-term capital gain or loss, as the case may be, and may not be deducted by the Company.

Nonqualified Stock Options.In general, no taxable income is realized by a participant upon the grant of an NQSO. Upon exercise of an NQSO, the participant generally would include in ordinary income at the time of exercise an amount equal to the excess, if any, of the fair market value of the Option Shares at the time of exercise over the exercise price paid for the Option Shares. In the event of a subsequent sale of Option Shares received upon the exercise of an NQSO, any appreciation or depreciation of the shares after the date on which taxable income is realized by the participant in respect of the option exercise will be taxed as capital gain in an amount equal to the excess of the sale proceeds for the Option Shares over the participant’s basis in such Option Shares. The participant’s basis in the Option Shares will generally equal the amount paid for the Option Shares plus the amount included in ordinary income by the participant upon exercise of the NQSO. The Company generally will have a deduction in an amount equal to the amount of ordinary income recognized by the participant in the Company’s tax year during which the participant recognizes the ordinary income.

15The terms of the Settlement and certain related matters are described in detail in the Company’s Current Report on Form 8-K filed with the SEC on October 12, 2018.

The Amended and Restated Regeneron Pharmaceuticals, Inc. 2014 Long-Term Incentive Plan is the only plan currently used by the Company to grant equity awards.
2The equity compensation plan not approved by the security holders is the Executive Stock Purchase Plan. It was adopted in 1989 and provides for the Compensation Committee of the board of directors to award employees, directors, consultants, and other individuals who render service to the Company the right to purchase Class A stock at a price set by the Compensation Committee. The Plan provides for the vesting of shares as determined by the Compensation Committee; should the Company’s relationship with a Plan participant terminate before all shares are vested, unvested shares will be repurchased by the Company at a price per share equal to the original amount paid by the Plan participant. As of December 31, 2019, there were no unvested shares and 44,246 shares of Class A stock available for future grants under the Plan.
3This amount includes (i) 28,609,277 shares to be issued upon exercise of outstanding options, (ii) 60,627 shares to be issued upon vesting of RSUs, and (iii) 59,396 shares to be issued upon vesting of PSUs (assuming maximum payouts earned) .
4The calculation of the weighted-average exercise price does not include the 60,627 shares to be issued upon vesting of RSUs or the 59,396 shares to be issued upon vesting of PSUs (assuming maximum payouts earned), as RSUs and PSUs do not have an exercise price.
5This amount is net of 1,041,763 outstanding RSAs. As these shares are considered issued and outstanding upon grant, they are not included in the amounts reported in column (a).

This proxy statement uses non-GAAP net income and non-GAAP net income per share, which is aare financial measuremeasures that isare not calculated in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"(“GAAP”). We believeThese non-GAAP financial measures are computed by excluding certain non-cash and other items from the related GAAP financial measure. Non-GAAP adjustments also include the estimated income tax effect of reconciling items. The Company makes such adjustments for items the Company does not view as useful in evaluating its operating performance. For example, adjustments may be made for items that the presentation of this non-GAAP measure is useful to investors because it excludes (i) non-cash share-based compensation expense, which fluctuatesfluctuate from period to period based on factors that are not within the Company'sCompany’s control such(such as the Company'sCompany’s stock price on the dates share-based grants are issued; (ii) the incremental charge recorded in the third quarter of 2014 related to the issuance of the final IRS regulations that provide guidance on the annual fee imposed by the Patient Protection and Affordable Care Act (the final IRS regulations differed from the temporary regulations issued in 2011 which resulted in the recognition of a catch-up adjustment); (iii) non-cash interest expense related to the Company's convertible senior notes, since this is not deemed useful in evaluating the Company's operating performance; (iv) loss on extinguishment of debt, since this non-cash charge is based on factorsissued) or items that are not within the Company's control;associated with normal, recurring operations (such as changes in applicable laws and (v) income tax expense for 2014, which was principally a non-cash expense due primarily to utilization of net operating loss and tax credit carryforwards, and deductions related to employee stock option exercises. In 2015, income tax expense adjustments consider the tax effect of reconciling items and an adjustment from GAAP tax expense to the amount of taxes that are paid or payable in cash in respect of the current period. As there is a significant difference between the Company's effective tax rate and actual cash income taxes paid or payable, GAAP income tax expense is not deemed useful in evaluating the Company's operating performance.regulations).

In such event, the Company shall deliver to the Participant the number of shares of Company Stock for which the Option was deemed exercised, less the number of shares of Company Stock required to be withheld for the payment of the total purchase price and required withholding taxes; provided, however, any fractional shares of Company Stock shall be settled in cash.

The Committee shall determine the expiration date of each Stock Appreciation Right.
(B)Upon the exercise of a Stock Appreciation Right, the holder shall have the right to receive the excess of (i) the Fair Market Value of one share of Company Stock on the date of exercise (or such amount less than such Fair Market Value as the Committee shall so determine at any time during a specified period before the date of exercise) over (ii) the grant price of the Stock Appreciation Right.
(C)The Committee shall determine in its sole discretion whether payment on exercise of a Stock Appreciation Right shall be made in cash, in whole shares of Company Stock or other property, or any combination thereof.

In such event, the Company shall make payment to the Participant in accordance with this Section, reduced by the number of shares of Company Stock (or cash) required for withholding taxes; any fractional share of Company Stock shall be settled in cash.

Without the approval of the Company’s shareholders, other than pursuant to Section 3(e) hereof, the Committee shall not (i) reduce the grant price of any Stock Appreciation Right after the date of grant, (ii) cancel any Stock Appreciation Right when the grant price per Share exceeds the Fair Market Value of one share of Company Stock in exchange for cash or another Award (other than in connection with a Change in Control), or (iii) take any other action with respect to a Stock Appreciation Right that would be treated as a repricing under the rules and regulations of the principal U.S. national securities exchange on which the shares of Company Stock are listed.
