CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

2020 Proxy Statement Summary

Pay-for-Performance

Rewarding improvement in our financial and operating results and the creation of stockholder value are key characteristics of our compensation philosophy, which serves as the foundation of our executive compensation program. To align the interests of our executives with those of our stockholders, the focus of our executive compensation program is on incentive compensation that emphasizes "pay-for-performance," rewarding our executives for performance against pre-established financial goals and total stockholder return ("TSR"). Our executive compensation program is discussed in detail in section "VIII. Executive Compensation" starting on page 30.

Alignment of Pay and Performance

We seek to align the interests of our named executive officers ("NEOs"), including our chief executive officer ("CEO"), with the interests of our stockholders. Our executive compensation program aligns a significant portion of our NEOs' compensation with the total return experienced by our stockholders. The graph below illustrates the alignment between our CEO's compensation and the returns experienced by our stockholders over the last three years.

2019 Pay Components

As part of our executive compensation program, we provide our NEOs with base salary, short-term incentives and long-term incentives. We allocate compensation among these components based on our belief that the majority of executive compensation should be paid in the form of performance-based, variable compensation, with a greater emphasis on "at risk" pay for senior executives who have greater responsibility for the business.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

2020 Proxy Statement Summary

As illustrated below, the compensation pay mix for our CEO and our other NEOs during 2019 reflects our objectives of linking pay to performance and aligning executives' interests with those of our stockholders. The compensation pay mix for "All Other NEOs" reflects the average compensation for all of our NEOs as a group, excluding the CEO, for fiscal 2019. For an individual breakdown of the compensation allocation for each of our NEOs, see "VIII. Executive Compensation—Compensation Disclosure and Analysis—Elements of Executive Compensation Benefits" starting on page 33.

The following illustrates the make-up of, and performance metrics attributable to, the short-term and long-term incentives awarded to our NEOs. For additional information on the short-term and long-term incentives, see "VIII. Executive Compensation—Compensation Discussion and Analysis—Elements of Executive Compensation and Benefits."



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

2020 Proxy Statement Summary

Say-on-Pay

Our stockholders have historically approved our say-on-pay proposal at a high rate, with 98.84% of votes cast in favor of our executive compensation program in 2019. The following chart shows the Company's say-on-pay advisory vote approval rates for the past 5 years.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Unless this proxy statement ("Proxy Statement") indicates otherwise or the context otherwise requires, the terms, "we," "our," "our Company," "the Company" or "us" as used in this Proxy Statement refer to Crown Castle International Corp. and its predecessor (organized in 1995), as applicable, each a Delaware corporation (together, "Crown Castle International Corp.").

II. INFORMATION ABOUT VOTING

Solicitation of Proxies. The Board of Directors ("Board") of Crown Castle International Corp. is soliciting proxies for use at our 2020 Annual Meeting of Stockholders ("Annual Meeting") and any adjournments or postponements of the Annual Meeting.

This Proxy Statement, the form of proxy and our 2019 Form 10-K are being distributed or made available via the Internet to our stockholders on or about March 30, 2020.

Notice of Internet Availability of Proxy Materials. Pursuant to Securities and Exchange Commission ("SEC") rules regarding the electronic distribution of proxy materials, we have elected to provide access to our proxy materials on the Internet, instead of mailing the full set of printed proxy materials, which allows us to reduce costs associated with the Annual Meeting. On or about March 30, 2020, we intend to send to most of our stockholders a Notice of Internet Availability of Proxy Materials ("Proxy Materials Notice") containing instructions on how to access our Proxy Statement and 2019 Form 10-K and how to submit a proxy. If you receive a Proxy Materials Notice, you will not receive a printed copy of the proxy materials in the mail unless you request it. If you would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials included in the Proxy Materials Notice.

Agenda Items. The agenda for the Annual Meeting is to consider and vote upon the following matters:


•	the election of 12 directors for a one-year term;


•	the ratification of the appointment of PricewaterhouseCoopers LLP ("PwC") as our independent registered public accountants for fiscal year 2020;


•	a non-binding, advisory vote to approve the compensation of our named executive officers; and


•	such other business as may properly come before the Annual Meeting.

Who can Vote. You can vote at the Annual Meeting if you are, on the Record Date (as defined below), a holder of record of our common stock, par value of $0.01 per share ("Common Stock"). The record date for determining the stockholders entitled to notice of, and to vote at, the Annual Meeting is the close of business on March 20, 2020 ("Record Date"). Holders of Common Stock will have one vote for each share of Common Stock owned of record as of the Record Date. As of the close of business on the Record Date, there were 416,749,469 shares of Common Stock outstanding.

A complete list of the stockholders entitled to vote at the meeting will be available for examination by any stockholder of record at our offices located at 1220 Augusta Drive, Suite 600, Houston, Texas 77057 for a period of 10 days prior to the Annual Meeting. The list will also be available for examination by any stockholder of record present at the Annual Meeting.

How to Vote. You may submit your proxy for your shares in any of the following ways:


•	if you receive a printed proxy card, mark, sign, date and return the proxy card (see instructions on the Proxy Materials Notice on how to request a printed proxy card);


•	call 1-800-690-6903 to submit a proxy by telephone; or


•	visit www.proxyvote.com to submit a proxy via the Internet.

Alternatively, you may vote at the Annual Meeting. If you are a beneficial owner whose shares are held in the name of a bank, broker or other nominee, you must obtain a legal proxy, executed in your favor, from the stockholder of record (that is, your bank, broker or nominee) to be able to vote at the Annual Meeting.

Have your Proxy Materials Notice, proxy card or voting instruction form in front of you when submitting a proxy by telephone or the Internet. It contains important information that is required to access the system.

You must submit your proxy by 11:59 p.m. Eastern Time on May 13, 2020.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

How to Vote as a Participant in the Crown Castle International Corp. 401(k) Plan. If you are a participant in the Crown Castle International Corp. 401(k) Plan ("401(k) Plan"), your proxy card, or a proxy submitted by telephone or through the Internet, will also serve as voting instructions to Charles Schwab Bank, as trustee for the 401(k) Plan ("Trustee"), with respect to shares of Common Stock allocable to your 401(k) Plan account as of the Record Date.

If you provide voting instructions with respect to shares of Common Stock allocable to your 401(k) Plan account, the Trustee will vote those shares in the manner specified. If you fail to provide timely instructions, the independent fiduciary for the 401(k) Plan will instruct the Trustee to vote such shares of Common Stock in the same proportion as shares of Common Stock for which voting instructions have been timely and properly received from other 401(k) Plan participants, unless required by applicable law to exercise discretion in voting such shares.

To allow sufficient time for the Trustee to vote your shares, voting instructions from 401(k) Plan participants must be received by 11:59 p.m. Eastern Time on May 11, 2020.

Use of Proxies. All proxies that have been timely and properly submitted – whether by Internet, telephone or mail – and not revoked will be voted at the Annual Meeting in accordance with your instructions. If you sign your proxy card but do not give voting instructions, the shares represented by that proxy will be voted as recommended by the Board. The Board recommends the following vote for each of the proposals to be considered and voted upon at the Annual Meeting:


•	FOR the election of each of the director nominees named in this Proxy Statement (Proposal 1);


•	FOR the ratification of the appointment of PwC as our independent registered public accountants for fiscal year 2020 (Proposal 2); and


•	FOR the non-binding, advisory vote to approve the compensation of our named executive officers (Proposal 3).

If any other matters are properly presented at the Annual Meeting for consideration and if you have submitted a proxy for your shares by Internet, telephone or mail, the persons named as proxies in the proxy card will have the discretion to vote on those matters for you. As of the date we filed this Proxy Statement with the SEC, we do not know of any other matters to be raised at the Annual Meeting.

Revoking a Proxy. You may change your vote by revoking your proxy at any time before it is exercised.

If you are a stockholder of record, you can revoke your proxy by:


•	delivering a timely written notice of revocation to our Corporate Secretary, Crown Castle International Corp., 1220 Augusta Drive, Suite 600, Houston, Texas 77057;


•	submitting a timely, later-dated proxy by Internet, telephone or mail (see instructions on your Proxy Materials Notice or proxy card); or


•	attending the Annual Meeting and voting. Attendance at the meeting alone will not constitute a revocation of a proxy.

If you are a beneficial owner whose shares are held in the name of a bank, broker or other nominee, you may revoke your voting instructions by submitting new voting instructions to your bank, broker or other nominee before the applicable deadline shown above or, if you have obtained a legal proxy from your bank, broker or other nominee giving you the right to vote your shares, you may change your vote by attending the Annual Meeting and voting in person.

If you are a participant in the 401(k) Plan, you may revoke your voting instructions by submitting new voting instructions to the Trustee before the applicable deadline shown above.

Quorum Requirement. A quorum of stockholders is needed to hold a valid Annual Meeting. A quorum will exist to hold a valid Annual Meeting if the holders of at least a majority in voting power of the outstanding shares of Common Stock entitled to vote at the Annual Meeting attend the Annual Meeting in person or are represented by proxy. Abstentions and broker non-votes are counted as present for the purpose of establishing a quorum.

Vote Required for Action. Each director shall be elected (Proposal 1) by a majority of the votes cast by the holders of shares of Common Stock entitled to vote and present in person or represented by proxy (a majority of



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

the votes cast means that, to be elected, the number of votes cast "for" a nominee must exceed the number of votes cast "against" the nominee). The affirmative vote of the holders of a majority of the voting power of the shares of Common Stock present in person or represented by proxy at the annual meeting and entitled to vote on such matter is required to approve each of (1) the ratification of PwC as our independent registered public accountants for fiscal year 2020 (Proposal 2) and (2) the non-binding, advisory resolution to approve the compensation of our named executive officers (Proposal 3).

Generally, all other actions which may come before the Annual Meeting require the affirmative vote of the holders of a majority of the voting power of the shares of Common Stock present in person or represented by proxy at the Annual Meeting and entitled to vote on such matters.

With respect to all proposals other than the election of directors (Proposal 1), abstentions have the same effect as votes against, and broker non-votes have no effect. With respect to the election of directors, abstentions and broker non-votes are not counted as a vote cast "for" or "against" a nominee.

Attending the Annual Meeting. The Annual Meeting will be held on May 14, 2020 at 9:00 a.m. Central Time at our offices located at 1220 Augusta Drive, Suite 600, Houston, Texas 77057. We currently intend to hold the Annual Meeting in person. We continue to actively monitor the coronavirus (COVID-19) developments and the related recommendations and protocols issued by public health authorities and federal, state and local governments. We are sensitive to the public health and travel concerns that our various stockholders may have. Accordingly, we may elect to change the means of holding the Annual Meeting (including solely by means of remote communication), if we determine that it is not possible or advisable to hold an in-person meeting. If we make this change, we will promptly issue a press release with details on how to participate at the Annual Meeting. We will post the press release on our website at https://investor.crowncastle.com/ and file it with the SEC as additional proxy material. As always, we encourage you to vote your shares prior to the Annual Meeting.

You may attend the meeting if you are (1) a stockholder of record, (2) a legal proxy for a stockholder of record, or (3) a beneficial owner with evidence of ownership as of the Record Date (such as a letter from the bank, broker or other nominee through which you hold your shares confirming your ownership or a bank or brokerage firm account statement). If you are a stockholder of record who plans to attend the Annual Meeting, please mark the appropriate box on your proxy card (or note your intention to attend when prompted via Internet or telephone proxy submission). For all attendees, a valid picture identification must be presented in order to attend the meeting.

As noted above in "—How to Vote" of this section "II. Information About Voting," if you are a beneficial owner and wish to vote at the Annual Meeting, you must obtain a legal proxy, executed in your favor, from the bank, broker or other nominee through which you hold your shares and present it at the Annual Meeting. To request a legal proxy, please follow the instructions at the website listed on the Proxy Materials Notice.

If you are a beneficial owner and plan to attend the Annual Meeting, please send written notification in advance of the Annual Meeting to our Corporate Secretary at Crown Castle International Corp., 1220 Augusta Drive, Suite 600, Houston, Texas 77057, and enclose a copy of (1) evidence of your ownership as of the Record Date or (2) a legal proxy, executed in your favor, from the institution through which you hold your shares.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

III. PROPOSALS

1. Election of Directors

Pursuant to our Restated Certificate of Incorporation, all directors of the Board (other than any director who may be elected by the holders of any series of preferred stock) hold office for a term expiring at the first succeeding annual meeting of stockholders after their election, with each such director holding office until his or her successor shall have been duly elected and qualified ("Annual Term").

The nominees for director at the Annual Meeting are: P. Robert Bartolo, Jay A. Brown, Cindy Christy, Ari Q. Fitzgerald, Robert E. Garrison II, Andrea J. Goldsmith, Lee W. Hogan, Edward C. Hutcheson, Jr., J. Landis Martin, Robert F. McKenzie, Anthony J. Melone and W. Benjamin Moreland. Each of these nominees is currently a member of the Board. If elected at the Annual Meeting, each of the nominees shall hold office as a director for an Annual Term.

In accordance with our Amended and Restated By-laws ("By-Laws"), each incumbent director nominee has tendered an irrevocable resignation that will be effective upon (1) failure to receive the required vote for election at the Annual Meeting and (2) the Board's subsequent acceptance of such resignation. If an incumbent director nominee fails to receive the required vote for re-election, the Nominating & Corporate Governance Committee ("NCG Committee") and the Board should act to determine whether to accept or reject the resignation, or whether other action should be taken.

Each nominee has consented to be nominated and has expressed his or her intention to serve if elected. The Board expects that each of the nominees for director will be able and willing to serve as a director. If any nominee is not available, the proxies may be voted for another person nominated by the current Board, or the size of the Board may be reduced. Information about the nominees and the Board is contained in the next two sections of this Proxy Statement (see "IV. Board of Directors" and "V. Information About the Board of Directors").

The Board recommends a vote FOR the election of each of the 12 nominees named herein as directors.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

2. Ratification of Appointment of Independent Registered Public Accountants

The Audit Committee of the Board ("Audit Committee") has appointed PwC to continue to serve as our independent registered public accountants for fiscal year 2020. In the event the stockholders do not ratify the appointment, the appointment will be reconsidered by the Audit Committee. Approval of the resolution will in no way limit the Audit Committee's authority to terminate or otherwise change the engagement of PwC for fiscal year 2020.

We were billed for professional services provided with respect to fiscal years 2019 and 2018 by PwC in the amounts set forth in the following table.



Services Provided	2019		2018
Audit Fees (a)	$	3,295,000	$	3,584,596
Audit-Related Fees (b)	900		75,900
Tax Fees (c)	304,100		47,201
All Other Fees (d)	—		—
Total	$	3,600,000	$	3,707,697

(a)

Represents the aggregate fees billed for professional services rendered by PwC for the audit of our annual financial statements, review of financial statements included in our quarterly reports on Form 10-Q, services related to the audit of internal control over financial reporting, and other services normally provided by our independent auditor in connection with statutory and regulatory filings or engagements.


(b)	Represents the aggregate fees billed for assurance and related services by PwC that are reasonably related to the performance of the audit or review of our financial statements not reported as "Audit Fees." Audit-related fees for 2018 were for services in connection with discussions, reviews and testing of certain information related to new accounting standards in a year prior to adoption.


(c)	Represents the aggregate fees billed for professional services rendered by PwC for tax compliance, tax advice and tax planning.


(d)	Represents the aggregate fees billed for products and service provided by PwC other than those reported as audit, audit-related or tax fees above.

We expect a representative of PwC to attend the Annual Meeting. The representative will have an opportunity to make a statement if he or she desires and also will be available to respond to appropriate questions.

The Board recommends a vote FOR ratification of the appointment of PwC as our independent registered public accountants for fiscal year 2020.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

3. Non-binding, Advisory Vote to Approve the Compensation of Our Named Executive Officers

In accordance with the requirements of Section 14A of the Securities Exchange Act of 1934, as amended ("Exchange Act"), and the related rules, our stockholders have the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the SEC's compensation disclosure rules.

Accordingly, we are asking our stockholders to approve the following resolution at the Annual Meeting:

RESOLVED, that the stockholders of Crown Castle International Corp. ("Company") approve, on an advisory basis, the compensation of the named executive officers of the Company, as disclosed in the Company's Proxy Statement for the 2020 Annual Meeting of Stockholders pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative disclosure.

As described in "VIII. Executive Compensation—Compensation Discussion and Analysis" of this Proxy Statement, we seek to align the interests of our named executive officers with the interests of our stockholders. Our compensation programs are generally designed to reward our named executive officers for performance against pre-established financial goals and the TSR experienced by our stockholders, with a focus on variable, "at risk" incentive-based compensation that supports our "pay-for-performance" compensation philosophy. We believe that our executive compensation program is designed to attract, retain and motivate high-performing executives to lead our Company.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. The vote on this proposal is advisory, which means that the vote is not binding on the Company, our Board or the Compensation Committee of the Board ("Compensation Committee"). Nevertheless, the Board and the Compensation Committee value the opinions of our stockholders, and intend to consider any stockholder concerns evidenced by this vote and evaluate whether any actions are necessary to address those concerns.

The Board recommends a vote FOR the approval of the compensation of our named executive officers as disclosed in this Proxy Statement.

V. INFORMATION ABOUT THE BOARD OF DIRECTORS

Board Matrix

The following matrix provides information regarding the members of our Board, including certain types of knowledge, skills, experiences and attributes possessed by one or more of our directors which our Board believes are relevant to our business, industry or real estate investment trust ("REIT") structure. The matrix does not encompass all of the knowledge, skills, experiences or attributes of our directors, and the fact that a particular knowledge, skill, experience or attribute is not listed does not mean that a director does not possess it. In addition, the absence of a particular knowledge, skill, experience or attribute with respect to any of our directors does not mean the director in question is unable to contribute to the decision-making process in that area. The type and degree of knowledge, skill and experience listed below may vary among the members of the Board.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Board Leadership Structure

Since our initial public offering in 1998, the roles of Chairman of our Board and CEO have been served by two different persons at all times. Notwithstanding the foregoing, our Corporate Governance Guidelines provide that the Board does not maintain a firm policy with respect to the separation of the offices of Chairman and CEO. The Board believes that it is in the best interests of our stockholders for the Board to make a determination regarding the separation or combination of these roles each time it elects a new Chairman or CEO based on the relevant facts and circumstances applicable at such time.

Meetings

During 2019, the Board held five meetings (four regularly scheduled and one special). Each incumbent director attended at least 75% of the aggregate of (1) the total number of meetings of the Board during the period in which he or she was a director and (2) the total number of meetings of all Board committees ("Committees") on which he or she served during the period in which he or she was a director.

Our Corporate Governance Guidelines provide that, while the Board understands that scheduling conflicts may arise resulting in absences, the Board strongly encourages each director to attend our annual meeting of stockholders. Each of the directors serving on the Board at the time of our 2019 annual meeting of stockholders ("2019 Annual Meeting") attended the 2019 Annual Meeting.

The non-management members of the Board generally meet in executive session at each regularly scheduled meeting of the Board (typically four times per year). In addition, the Board meets at least once a year in executive session with only independent directors present. Our Corporate Governance Guidelines provide that if the Chairman of the Board is a non-management director, the Chairman of the Board shall preside at such executive sessions, and if the Chairman of the Board is a member of management, the non-management directors may elect a chairman to preside at such executive sessions.

Board Oversight of Risk

Management is responsible for assessing and managing our various exposures to risk on a day-to-day basis. Our Internal Audit department serves as the primary monitoring and testing function for company-wide policies and procedures, including policies and procedures regarding our risk management strategy. Such strategy includes identifying, evaluating and addressing potential risks that may exist at the enterprise, strategic, financial, operational, compliance and reporting levels. The Board is responsible for overseeing and assessing our risk management strategy. The Board exercises these responsibilities periodically as part of its meetings and also through the Board's four standing Committees, each of which examines various components of risk in connection with its responsibilities. Our Vice President—Internal Audit position reports to the Audit Committee, and provides periodic updates (generally quarterly) to the Audit Committee with respect to the Internal Audit department's activities, including with respect to risk management matters (including cybersecurity risks) and the audit agenda. In addition, an overall review of risk is inherent in the Board's consideration of our long-term strategies and in the transactions and other matters presented to the Board, including capital expenditures, acquisitions and divestitures, and financial matters. The Board's role in risk oversight is consistent with the Board's current leadership structure, with the CEO and other members of senior management having responsibility for assessing and managing our risk exposure, and the Board and its Committees providing oversight in connection with those efforts.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Executive Compensation Process and Procedures: Over the course of several meetings throughout the year, the Compensation Committee annually reviews executive compensation, including base salary, short-term incentive compensation, long-term incentive compensation and other benefits. In performing its duties, the Compensation Committee obtains input, as it deems necessary, from an independent compensation consultant ("Compensation Consultant") engaged directly by the Compensation Committee (while the Compensation Consultant is engaged by the Compensation Committee, it works with management, including members of our human resources department and our CEO, in developing compensation studies as directed by the Compensation Committee). For 2019, Meridian Compensation Partners served as the Compensation Consultant. In addition, in the case of compensation decisions relating to executives other than the CEO, the Compensation Committee seeks and obtains input from the CEO. The Compensation Committee regularly holds executive sessions at its meetings during which management, including the CEO, is not in attendance. Additional information regarding the Compensation Committee's processes and procedures for consideration and determination of executive compensation is provided below at "VIII. Executive Compensation—Compensation Discussion and Analysis."

•	advise the Board about appropriate composition of the Board and its Committees;


•	advise the Board about and recommend to the Board appropriate corporate governance practices and assist the Board in implementing those practices; and


•	oversee the annual evaluation of the Board and its Committees.

Common Stock Ownership and Retention Guidelines. The Board has adopted stock ownership and retention guidelines generally providing that each of our non-employee directors should seek to establish and maintain by the fifth anniversary of the date such director is appointed to the Board, beneficial ownership of a number of shares of Common Stock having a value sufficient to satisfy a stock ownership level of three times the Annual Equity Grant (defined below) (exclusive of the additional equity award amount for a non-employee Chairman of the Board) for non-employee directors (currently $180,000). A non-employee director generally has until the fifth anniversary after the date of an increase in the Annual Equity Grant to meet the incremental increase to the stock ownership level as a result of such Annual Equity Grant increase.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Common Stock retention guidelines for non-employee directors are substantially similar to those applicable to our executives as described in "VIII. Executive Compensation—Compensation Discussion and Analysis—Other Matters—Stock Ownership and Retention Guidelines" below.

Consideration of Director Nominees: The NCG Committee has the authority to recommend nominees for election as directors to the Board. In considering candidates for the Board, the NCG Committee takes into account the entirety of each candidate's credentials and, subject to the discussion below, currently does not maintain any specific minimum qualifications that must be met by an NCG Committee recommended nominee.

While the NCG Committee does not maintain a formal list of minimum qualifications in making its evaluation and recommendation of candidates, the NCG Committee will generally consider, among other factors, whether prospective nominees are able to read and understand basic financial statements, have relevant business experience, have industry or other specialized expertise and have high moral character. In addition, the NCG Committee considers issues of diversity, including with respect to experience, expertise, viewpoints, skills, race, ethnicity and gender, in connection with the director selection process. The NCG Committee may attribute greater or lesser significance to different factors at particular times depending upon the needs of the Board, its composition, or the NCG Committee's perception about future issues and needs.

The NCG Committee may consider candidates for the Board from any reasonable source, including from a third party search firm engaged by the NCG Committee or through stockholder recommendations (provided the procedures set forth below in "X. Other Matters—Stockholder Recommendation of Director Candidates" are followed). The NCG Committee does not intend to alter the manner in which it evaluates candidates based on whether the candidate is recommended by a stockholder. However, in evaluating a candidate's relevant experience, the NCG Committee may consider previous experience as a member of the Board.

The NCG Committee has considered the discussion of some commentators suggesting that lengthy Board tenure may not be desirable. The NCG Committee has structured the Board such that there are directors of varying tenures, with new directors and perspectives joining the Board every few years as circumstances warrant, while retaining the institutional memory of longer-tenured directors. The NCG Committee believes that longer-tenured directors, balanced with less-tenured directors, enhance the Board's oversight capabilities and its collective business acumen.


•	Strategy Committee

Number of Meetings in 2019: 4

Functions and Authority: The functions and authority of the Strategy Committee include:


•	support our executive management in developing and overseeing our strategic initiatives;


•	provide management with guidance and oversight on strategy development and execution; and


•	act as an advisor to the Board and management on strategy-related issues and direction.

Board Independence

The Board has affirmatively determined that each member of the Board standing for election at the Annual Meeting and each other director nominee, except Mr. Brown (our current President and CEO) and Mr. Moreland (our former President and CEO and EVC), has no material relationship with us and is an independent director, as defined under New York Stock Exchange ("NYSE") listing standards.

To assist in its determination of director independence, the Board has adopted certain categorical standards, as set forth on Appendix A hereto. The Board determined the independence of the aforementioned directors and director nominees taking into account such standards.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee during fiscal 2019, or as of the date of this Proxy Statement, is or has been one of our officers or employees. In addition, during 2019, none of our executive officers served on the compensation committee (or board, in the absence of a compensation committee) of any company that employed any member of our Compensation Committee or Board.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Certain Relationships and Related Transactions

Review of Transactions with Related Persons. From time to time we may engage in transactions with companies whose officers, directors or principals are executive officers or directors of ours or are family members of directors or executive officers of ours. The Board is primarily responsible for reviewing such transactions. In the course of its review and approval or ratification of such a transaction, the Board considers various aspects of the transaction it deems appropriate, which may include:


•	the nature of the related person's interest in the transaction;


•	the material terms of the transaction;


•	whether such transaction might affect the independent status of a director under NYSE independence standards;


•	the importance of the transaction to the related person and to us; and


•	whether the transaction could impair the judgment of a director or executive officer to act in the best interest of our Company.

Any member of the Board who is a related person with respect to a transaction under review does not participate in the vote relating to approval or ratification of the transaction.

We have various processes for identifying and reporting conflicts of interests, including related person transactions. Our Business Practices and Ethics Policy ("Ethics Policy") provides that each employee is expected to avoid engaging in business or conduct, or entering into agreements or arrangements, which would give rise to actual, potential or the appearance of conflicts of interest. The Ethics Policy also provides procedures for reporting any actual or potential conflicts of interest. In addition, we annually distribute and review a questionnaire to each of our executive officers and directors requesting certain information regarding, among other things, certain transactions with us in which he, she or any family member has an interest.

Board Compensation

The Board maintains a compensation arrangement for the Board's non-employee directors, subject to the NCG Committee's periodic review (a director who is also an employee of ours receives no additional compensation for services as a director). In the fourth quarter of 2018, the NCG Committee, with the assistance of the Compensation Consultant engaged for that year, reviewed the Board's non-employee director compensation arrangement. The NCG Committee reviewed a competitive market analysis prepared by such Compensation Consultant, comparing the Board's compensation arrangement to those of the companies comprising our Peer Group (as defined in "VIII. Executive Compensation—Compensation Discussion and Analysis" below). Based on the results of the competitive market analysis reviews, the NCG Committee determined, and the Board ratified, that no changes be made to the compensation program for non-employee directors at such time.

For 2019, the Board compensation arrangement was comprised of the following types and levels of compensation:

•

Initial Equity Grant. Each newly appointed non-employee director is permitted to receive a grant, pursuant to our 2013 Long-Term Incentive Plan ("2013 Plan"), of a number of unrestricted shares of Common Stock having a valuation equal to approximately $90,000, priced at the per share closing price of the Common Stock as of the effective date of the director's appointment or election ("Initial Equity Grant"); provided, that if a director is appointed or elected on or about the date of an Annual Equity Grant (defined below), the director generally receives the Annual Equity Grant in lieu of an Initial Equity Grant. There were no Initial Equity Grants in 2019.

•

Annual Equity Grant. Each year, at the Board's first regularly scheduled meeting, each non-employee director is typically granted shares of Common Stock (or a pro-rated amount for any director not expected to serve past that year's annual meeting of stockholders).

VIII. EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis ("CD&A") is a summary of our compensation arrangements for our NEOs (defined below) and contains certain statements regarding Company performance targets and goals. These targets and goals are disclosed in the limited context of the CD&A and should not be construed to be statements of management's expectations or estimates of results or other guidance. We caution investors not to apply these statements to other contexts.

Throughout this Proxy Statement, the individuals who served as our CEO and CFO during 2019, as well as the other named executive officers included in the table below at "—Summary Compensation Table" in this "VIII. Executive Compensation" are referred to as "NEOs."

Executive Summary

Rewarding improvement in our financial and operating results and the creation of long-term stockholder value are key characteristics of our compensation philosophy, which serves as the foundation of our executive compensation program. In order to align the interests of our executives with those of our stockholders, the focus of our executive compensation program is on incentive compensation that emphasizes "pay-for-performance," rewarding our executives for performance against pre-established financial goals and TSR.

To emphasize the importance of "pay-for-performance" in our executive compensation program, our incentive compensation elements are linked directly to specific performance measures.

The short-term incentive element of our executive compensation program rewards our executives, generally in the form of cash-based annual incentive awards ("Annual Incentives"), for the achievement of one or more financial performance measures. For 2019, as a result of our financial results, the Annual Incentives awarded pursuant to our 2019 Executive Management Team Annual Incentive Plan ("AIP") were paid at above-target levels. Details regarding Annual Incentives for our executives are provided at "—Elements of Executive Compensation and Benefits—Short-Term Incentives" in this CD&A.

For 2019, the long-term incentive element of our executive compensation program was delivered in the form of RSUs, 35% of which vest based on the passage of time over a three-year period ("Time RSUs") and the remaining 65% of which may vest based on our TSR relative to pre-established benchmarks ("Performance RSUs"). For 2019, the Compensation Committee (for purposes of this CD&A, "Committee") approved the grant of Performance RSUs in two forms: (a) Relative TSR Performance RSUs and (b) Absolute TSR Performance RSUs (each as defined below). Details regarding RSUs awarded to our executives as long-term incentives are provided at "—Elements of Executive Compensation and Benefits—Long-Term Incentives" in this CD&A.

Other notable highlights of our executive compensation program include:


•	The Committee consists of independent directors and regularly meets in executive session without management present.


•	The Committee has engaged an independent Compensation Consultant and annually assesses the Compensation Consultant's performance.


•	The Committee reviews each executive's annual and historical compensation prior to making compensation decisions.


•	We mitigate potential risks associated with compensation through the use of caps on potential incentive payments, stock ownership and retention guidelines, and multiple performance metrics.


•	We do not enter into employment agreements with executives.


•	We enter into severance agreements with executives which, in the case of a change in control, require both a qualified change in control and termination of employment for severance and other benefits to be paid.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT


•	The Committee has approved a policy not to enter into any agreement providing for an Excise Tax Payment (defined below), and Excise Tax Payment provisions are not present in any agreement with any executive.


•	We have adopted stock ownership and retention guidelines which provide that our executives establish and maintain ownership of shares of our Common Stock with a value equal to or greater than established multiples of base salary.


•	We have adopted a recoupment policy which provides that, in the event of a financial restatement or a determination by the Board that misconduct by an NEO caused financial or reputational harm to the Company, the Compensation Committee will review the circumstances and make recommendations to the Board as to whether recoupment should be pursued.


•	We offer no perquisites or health and welfare benefits to executives other than those that are offered to all of our employees.


•	We target total direct compensation levels for executives at approximately the 50^th percentile of market.


•	Our insider trading policy includes anti-hedging provisions. For more information about our anti-hedging policy, see "—Other Matters—Anti-Hedging Policy" in this CD&A.

At the 2019 Annual Meeting, we submitted our executive compensation program to an advisory stockholder vote. The stockholders overwhelmingly approved our executive compensation program, with 98.84% of votes cast in favor of the proposal (based upon the voting power represented by shares of Common Stock present or represented by proxy at the 2019 Annual Meeting). The Committee has interpreted this vote to mean that our stockholders are supportive of our overall executive compensation philosophy and program.

Executive Compensation Program Overview

Our executive compensation program is established as a component of our total rewards program. Our total rewards program includes:


•	Compensation:


•	base salary


•	short-term incentives


•	long-term incentives


•	Health and welfare benefits:


•	401(k) Plan


•	medical, dental and vision benefits


•	life insurance benefits


•	paid time off


•	Learning and development:


•	training


•	performance management


•	career development

Our executive total rewards strategy is to provide a competitive mix of total rewards that enables us to effectively recruit, motivate and retain high-performing executives. With respect to the portion of total rewards for our executives that takes the form of compensation, it is our belief that a majority of such compensation should be variable, "at risk" and paid based on our financial results and TSR, in order to align our executives' interests with those of our stockholders.

The Committee is primarily responsible for evaluating and determining the compensation levels of our senior officers (namely, our CEO and the executive officers who report directly to our CEO) and administers our equity-based incentive plan and other compensation plans. The Board further reviews the actions of the Committee relating to the compensation of the CEO and certain senior officers (matters involving CEO compensation are subject to approval of the independent directors of the Board). Where this CD&A contains language indicating that the Committee has approved or taken action with respect to a matter, such language is also intended to indicate that the Board (or the independent directors, as applicable) has approved or taken any action required with respect to such matter.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

In performing its duties, the Committee obtains input, as it deems appropriate, from the Compensation Consultant, Meridian Compensation Partners, which is engaged directly by the Committee (while the Compensation Consultant is engaged by the Committee, it works with management, including members of our human resources department and our CEO, in conducting compensation studies as directed by the Committee). In addition, in the case of compensation decisions relating to executives other than the CEO, the Committee seeks and obtains input from the CEO. The Committee regularly holds executive sessions at its meetings during which management, including the CEO, is not in attendance. Management, including members of our human resources department and our CEO, assists with the coordination, preparation and review of Committee meeting materials.

Executive Compensation Program Objectives

General

The principal objectives of our executive compensation program are to:


•	provide a fair and competitive mix of compensation opportunities to attract, motivate and retain qualified, skilled and high-performing executives necessary for our long-term success;


•	reward our executives by utilizing a "pay-for-performance" approach to compensation, the goal of which is to create meaningful links between financial performance and the level of the executive's compensation;


•	motivate executives to make sound business decisions that improve stockholder value and reward such decisions;


•	balance the components of compensation so that the accomplishment of short-term and long-term operating and strategic objectives is encouraged and recognized;


•	encourage achievement of objectives by our executives within a team environment; and


•	foster an equity ownership culture that aligns our executives' long-term interests with those of our stockholders.

The Committee has established a number of processes to assist it in ensuring that our executive compensation program is achieving these objectives as detailed below.

Competitive Market Analysis

The Committee determines the levels for base salary, short-term incentives and long-term incentives by engaging, on an annual basis, in a competitive market analysis with respect to each of these compensation elements for each executive position ("Competitive Market Analysis"). The Committee usually begins this Competitive Market Analysis in the third quarter of the year prior to the year in which compensation decisions are made with respect to most matters, which decisions are typically made at the first regularly scheduled Committee meeting of each year (usually held in February) ("First Regular Committee Meeting"). Market data used in the Committee's Competitive Market Analysis includes general industry market data and peer group data.

•

General Industry Market Data. For certain executive positions, general industry market data from third-party proprietary compensation surveys, as analyzed by the Compensation Consultant, is reviewed by the Committee. This market data provides information regarding elements and levels of executive compensation relating to general industry companies that have participated in the surveys. The Committee utilizes this data since we do not recruit executives exclusively from the communications infrastructure, telecommunications and REIT industries (e.g., a financial executive with cross-industry skills may be recruited from another industry).


•	Peer Group Data. Each year the Committee considers public companies in the communications infrastructure, telecommunications and REIT industries of comparable size in terms of revenue, market capitalization and assets to comprise a peer group ("Peer Group") for which compensation data is obtained and reviewed by the Committee.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

The Peer Group companies used in the Competitive Market Analysis for gauging the elements of executives' 2019 compensation were:

In addition to the foregoing data, the Compensation Consultant may analyze and provide additional market data regarding best practices and compensation plan design from the Peer Group and other sources as requested by the Committee. The market data described above is used by the Committee in the Competitive Market Analysis to make decisions regarding executive compensation. No single group, survey or set of market data is used by the Committee as the sole gauge for determining executive compensation; rather, the information is used collectively, and no formulaic quantitative methodology is used by the Committee when using such data to determine executive compensation.

Assessment of Individual and Company Performance

In addition to market data, the Committee considers other factors in connection with its evaluation and determination of the components of compensation. These other factors may include our financial and operating performance, the applicable executive's individual performance, the executive's level of experience, the size of year-over-year changes in compensation and the duties and level of a particular executive position. These measures are discussed in more detail below.

Total Compensation Review

Through the Competitive Market Analysis and in its deliberations regarding executive compensation decisions, the Committee reviews and compares the individual components of compensation and the total compensation for each NEO against the market data. In addition, the Committee reviews year-over-year changes in compensation for each NEO against the market data. These analyses are an important aspect of the Committee's regular executive compensation decision-making process.

Elements of Executive Compensation and Benefits

General

The principal elements of compensation and benefits provided to our executives, each of which is discussed in more detail below, include the following:


•	base salary;


•	short-term incentive compensation;


•	long-term incentive compensation; and


•	other benefits, including retirement benefits, health and welfare benefits and severance benefits.

The distribution of compensation among its various components is driven by our belief that the majority of executive compensation should be paid in the form of performance-based, variable compensation, with a greater emphasis on "at risk" pay for senior executives who have greater responsibility for the business. The practice of emphasizing variable compensation suits our objectives of linking pay to performance and aligning executives' interests with those of our stockholders.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

The following chart shows the approximate allocation of actual base salary, Annual Incentives and RSUs for 2019 (as shown in "—Summary Compensation Table" in this "VIII. Executive Compensation") among fixed, short-term variable and long-term variable compensation for our NEOs:

2019 NEO Actual Total Direct Compensation Allocation

The distribution of compensation among the fixed element of base salary (paid in cash) and the variable elements of Annual Incentives (paid in cash) and RSUs (settled in shares of Common Stock) is primarily influenced by (1) our objective to utilize a "pay-for-performance" approach to compensation, which places a majority of each executive's variable compensation "at risk" based on the achievement of multiple performance objectives, (2) the Competitive Market Analysis and (3) the Committee's desire to balance short-term and long-term goals.

As noted above, in lieu of targeting each specific compensation element at a specified percentile of market, the Committee seeks to target total direct compensation (i.e., the sum of base salary, target level of Annual Incentive, and target level of Annual RSUs (defined below)) for our executives at approximately the 50^th percentile of market, while continuing to provide our executives with the opportunity to earn actual total direct compensation above the 50^th percentile should our performance exceed predetermined criteria and below the 50^th percentile should our performance fall short of such criteria. The Committee believes that targeting these levels of compensation aligns with our overall total rewards strategy, which in turn helps us achieve our executive compensation objectives and supports our long-term success.

Base Salary

Base salary is one of the main components of cash compensation for our executives. We choose to provide base salary compensation because it fits into our overall compensation objectives by providing a foundation for attracting and retaining executives and establishing a minimum level of compensation upon which our executives may rely. In addition to providing a base salary that is competitive with the market, we set base salary compensation to reflect the scope and level of responsibility for the applicable executive position. As described above, each year we conduct a Competitive Market Analysis for each executive position, based on the unique responsibilities of each position.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

The Committee bases its decisions regarding base salary on multiple factors, including the performance of the executive, considering such executive's contribution, accountability and experience, as well as the executive's base salary as compared to the Competitive Market Analysis.The Committee reviews recommendations made by the CEO with regard to base salary for executives other than himself and then either approves or revises these base salaries. The Committee independently reviews the performance of the CEO when determining and approving the base salary for the CEO. At the First Regular Committee Meeting of 2019:


•	Mr. Brown's base salary was increased from $925,000 to $1,000,000.


•	Mr. Schlanger's base salary was increased from $535,500 to $570,000.


•	Mr. Young's base salary was increased from $594,600 to $612,500.


•	Mr. Ackerman's base salary was increased from $450,000 to $480,000.


•	Mr. Simon's base salary was increased from $557,000 to $573,800.

The above base salary adjustments, as applicable, were made to better align base salary compensation with that of similarly situated executives at the Peer Group companies, as reviewed by the Committee in the Competitive Market Analysis.

Short-Term Incentives

The short-term incentive component of compensation represents a significant portion of the overall cash compensation opportunity for our executives. Short-term incentives are a variable element of compensation that are generally linked to specific short-term financial objectives.

Our short-term incentives are generally "at risk," meaning they are earned based upon meeting certain performance goals and may be earned at above-target or below-target levels based on the degree of achievement of those goals. In order to accomplish its overall executive compensation objectives, the Committee has identified the following objectives for developing the overall framework of the short-term incentive program. The program should:


•	be performance-based;


•	promote a short-term perspective among executives to complement the long-term perspective promoted by the long-term incentive program, while avoiding excessive risk;


•	be competitive with the market;


•	motivate executives by providing the appropriate rewards for corporate performance based on our goals and objectives;


•	reinforce the importance of company-wide teamwork; and


•	link the financial measures with stockholder expectations.

Annual Incentives

To achieve the above objectives, our short-term incentives for executives are generally comprised of performance-based Annual Incentives paid in accordance with an annually approved AIP. The AIP is a cash-based, short-term incentive award program that provides executives with the opportunity to earn an annual cash incentive if certain annual performance goals are achieved. Performance goals are pre-established based on the annual expectations for our business and are meant to be challenging, yet achievable. The Compensation Consultant has reviewed the performance goals and has noted that the performance goals represent meaningful targets that are challenging and indicative of value creation. The performance period covered by the AIP is from January 1 to December 31 of the applicable calendar year.

Annual Incentive Opportunity. Under the AIP, each executive has threshold, target and maximum Annual Incentive opportunities that are aligned with threshold, target and maximum performance outcomes. In the event of incremental outperformance over threshold or target, Annual Incentives that may be earned by the executive officers increase incrementally. In the event actual performance is below the pre-established threshold level for any performance goal, no Annual Incentive is earned with respect to that specific performance goal.

For 2019, each executive was eligible to earn between 0% and 175% of such executive's target opportunity under the AIP. To mitigate excessive risk, Annual Incentives are capped at the maximum payout opportunity even if actual performance exceeds the maximum performance goal. These payout ranges were determined by the Committee at the time the AIP was designed after consultation with, and a review of information provided by, the Compensation Consultant; this determination was based on relevant market data discussed above and was considered in the



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

review of total compensation previously discussed. The following table illustrates the 2019 Annual Incentive opportunities and actual awards as a percentage of base salary for each NEO.



		Percentage of Base Salary
Name	Title	Minimum	Threshold	Target	Maximum	Actual
Jay A. Brown	President & CEO	0.0%	85.0%	170.0%	297.5%	212.0%
Daniel K. Schlanger	SVP & CFO	0.0%	50.0%	100.0%	175.0%	124.7%
James D. Young	SVP & COO—Fiber	0.0%	50.0%	100.0%	175.0%	124.7%
Robert C. Ackerman	SVP & COO—Towers & Small Cells	0.0%	50.0%	100.0%	175.0%	124.7%
Kenneth J. Simon	SVP & General Counsel	0.0%	50.0%	100.0%	175.0%	124.7%

Annual Incentive Performance Goals. Short-term incentives that could be earned under the AIP were formulaically linked to the following financial performance metrics:


•	Adjusted EBITDA


•	Adjusted Funds from Operations ("AFFO") per Share

The performance goals used in connection with determining the NEOs' 2019 Annual Incentives ("2019 Goals") were approved by the Committee at the First Regular Committee Meeting of 2019, held on February 20, 2019. As in other recent years, the 2019 Goals were comprised of two financial metrics, Adjusted EBITDA and AFFO per Share, and the levels at which the 2019 Goals were established were based on the Board-approved financial budget and the full year guidance provided to investors in the fourth quarter of the preceding year, with "target" goals representing the midpoint of our initial full year outlook. The 2019 Goals were set prior to the determination by the Company that its historical accounting practice regarding the timing of revenue recognition for its tower installation services (“Pre-Restatement Accounting Practice”) was not acceptable under GAAP, as discussed in the 2019 10-K. The related restatement of certain of our financial statements to reflect the correct GAAP practices (“Accounting Restatement,” and the revised practices, “Post-Restatement Accounting Practice”), as described in the 2019 10-K, impacted the calculation of both Adjusted EBITDA and AFFO per Share for full year 2019.

In connection with approving awards under the AIP, the Committee determined that using full year 2019 results calculated based on the Pre-Restatement Accounting Practice was the appropriate methodology for determining the AIP results. In reaching this determination, the Committee reviewed all relevant facts and circumstances and determined that the Pre-Restatement Accounting Practice was the appropriate methodology because, among other things: (1) the goals set using the Pre-Restatement Accounting Practice represented appropriate targets for management, and 2019 Adjusted EBITDA and AFFO per Share, as calculated under the Pre-Restatement Accounting Practice, are appropriate measures of Company performance for purposes of determining 2019 Annual Incentives; (2) using the Post-Restatement Accounting Practice to determine the AIP results would cause a mismatch of methodologies and lead to an inaccurate measure of performance; and (3) there has been no finding by the Board of misconduct on the part of management or other employees that led to the Accounting Restatement. The Committee understood that using the Post-Restatement Accounting Practice results against the 2019 Goals, which were determined using the Pre-Restatement Accounting Practice, would have resulted in substantially reduced payouts because they would be based on two inconsistent methodologies. Accordingly, the Committee determined it was appropriate to apply a consistent methodology for measuring both goals and results.

The following table lists the 2019 Goals and results used in connection with determining the NEOs' 2019 Annual Incentives.



	Annual Incentive Financial Performance Zone (a)				Actual Multiple of Target (a)
Performance Metrics	Threshold	Target	Maximum	Actual	Actual Multiple of Target (a)
Adjusted EBITDA ($ in millions)^(b)	$3,257.20	$3,325.50	$3,553.30	$3,404.30	1.26
AFFO per Share^(b)	$5.71	$5.85	$6.10	$5.93	1.23


(a)	As noted above, the 2019 Goals and results were determined based on the Pre-Restatement Accounting Practice.


(b)	See Appendix B for definition of this non-GAAP financial measure.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

For each NEO, the Annual Incentive is financially-driven, based on an objective formula that equally weighs the two performance metrics of Adjusted EBITDA and AFFO per Share.

There are also two additional performance requirements for an Annual Incentive:


•	A minimum financial performance level of 95% of budgeted Adjusted EBITDA must be achieved for any executive to be eligible for an Annual Incentive; and

•

The business units or departments for which the executives are responsible must receive an acceptable assessment of applicable internal control over financial reporting for the previously completed fiscal year, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 ("404 Assessment"). Receipt of a 404 Assessment with a material weakness may result in a reduction or elimination of the potential Annual Incentives for the responsible executives and potentially all of the executives. In connection with the 2019 Annual Incentives, the Committee determined, based on the facts and circumstances, that no reduction or elimination of the 2019 Annual Incentives as a result of a material weakness was warranted.

For 2019, each NEO received an Annual Incentive equal to approximately 125% of target, which is based upon the performance and AIP parameters described above.

Additional details regarding Annual Incentives for the NEOs are provided below in the tables and related footnotes at "—Summary Compensation Table" and "—Grants of Plan-Based Awards in 2019" in this "VIII. Executive Compensation."

Long-Term Incentives

The objectives of our long-term incentive program are to:


•	align a significant portion of our executives' compensation with the total return experienced by our stockholders;


•	provide a means for our executives to accumulate shares of Common Stock in order to foster an "ownership culture"; and


•	serve as a retention vehicle for our executives.

The long-term incentive component represents the largest portion of the overall value of the total compensation program for our executives. In its assessment of long-term incentives, the Committee, with the assistance of our Compensation Consultant, generally considers the economic climate, executive compensation market data and our business needs. In doing so, the Committee has determined that a mix of performance-contingent equity and time vesting equity appropriately achieves our executive long-term incentive program objectives. In order to accomplish its overall objectives, the Committee has identified the following principles for administering the long-term incentive program. The program should:


•	align executives with stockholders to maximize TSR;


•	balance "at risk" performance-based vesting with the stability of time-based vesting;


•	promote a long-term perspective among executives to complement the short-term perspective promoted by the Annual Incentives;


•	promote an ownership culture by facilitating the accumulation and retention of shares of Common Stock;


•	be efficient from a stockholder dilution perspective;


•	serve as a retention vehicle; and


•	provide stability to our overall compensation program.

Although our 2013 Plan (approved by our stockholders on May 23, 2013) permits the use of various types of equity compensation vehicles, the Committee believes the use primarily of a mix of performance-contingent RSUs and time vesting RSUs best meets the objectives outlined above. The Committee utilizes RSUs in various forms to meet these objectives.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

RSUs

General. There are three general categories of RSUs which the Committee has granted to executives in recent years, which generally have the vesting attributes noted below:

•

Annual RSUs ("Annual RSUs") are generally awarded once per calendar year as part of delivering a competitive total compensation package to executives. The Annual RSUs granted to executives have generally been comprised of a combination of (1) Performance RSUs that vest upon the satisfaction of certain Common Stock performance criteria over a certain period of time along with a time vesting component and (2) Time RSUs vesting solely pursuant to a time-based vesting criteria. Annual RSUs granted to non-executive employees are typically Time RSUs.


•	New Hire RSUs ("New Hire RSUs") are Time RSUs awarded to certain newly hired executives based on the position and role into which they are hired.


•	Promotion RSUs ("Promotion RSUs") are Performance RSUs or Time RSUs awarded to certain executives in recognition of a promotion to a new position or role.

Annual RSUs are generally approved by the Committee at the First Regular Committee Meeting of the year.

New Hire RSUs and Promotion RSUs subject to time vesting typically vest over a three-year period. No New Hire RSUs or Promotion RSUs were granted to any NEO in 2019. In addition, other RSUs ("Other RSUs") may be awarded to certain executives in a given year to meet specific business initiatives or compensation objectives (e.g., retention, merger integration, etc.) or to recognize certain executives for exceptional performance. No Other RSUs were granted to any NEO in 2019.

Dividend equivalents accrue with respect to RSUs while they remain outstanding and unvested (equal to the cash dividends paid with respect to each share of underlying Common Stock). The dividend equivalents are subject to the same forfeiture restrictions as the RSUs. The dividend equivalents are earned and paid in cash only with respect to those RSUs that actually vest at approximately the time of such vesting.

The table below illustrates the framework of the Annual RSUs.

Our framework for the Annual RSUs places an appropriate level of focus on performance-contingent vesting, which is targeted to 65% of the total grant value for the NEOs. We believe that by tying a portion of the award value to absolute TSR, the compensation realized by our NEOs will be better aligned with the actual returns experienced by our stockholders, regardless of the general economic climate.

2019 Annual RSUs. To support the "pay-for-performance" approach and maintain a significant portion of the executives' compensation "at risk," in the first quarter of 2019, the Committee authorized, as 2019 Annual RSUs, the grant to the NEOs and certain other key employees of a combination of (1) Time RSUs which time vest at 33.33%, 33.33% and 33.34%, respectively, on February 19 of each of 2020, 2021 and 2022; (2) Relative TSR



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Performance RSUs which may vest based on our TSR Rank (defined below) relative to the companies contained in the Standard and Poor's 500 index ("S&P 500 Index") over a three-year performance period as further described below ("Relative TSR Performance RSUs"); and (3) Absolute TSR Performance RSUs which may vest based on the absolute annualized total return of our stock ("Annualized TSR") compared to pre-established hurdles over a three-year performance period ("Absolute TSR Performance RSUs").

With respect to the 2019 Annual RSUs granted to the NEOs, the grant value mix was allocated approximately 35% to Time RSUs, 35% to Relative TSR Performance RSUs, and 30% to Absolute TSR Performance RSUs.¹ In connection with the 2019 Annual RSUs, the Committee authorized the grant of approximately (1) 695,236 Time RSUs to 2,222 employees, (2) 163,969 Relative TSR Performance RSUs to 72 employees, and (3) 291,200 Absolute TSR Performance RSUs to 72 employees, including 57,470 Time RSUs, 61,511 Relative TSR Performance RSUs, and 109,232 Absolute TSR Performance RSUs to the NEOs.

The Performance RSUs are issued pursuant to the 2013 Plan and represent a contingent right to receive Common Stock equal to 0% to 150% of the target number of Performance RSUs.² Vesting of the Performance RSUs is subject to (1) the level of achievement against the relevant performance criteria over a three-year performance period (beginning January 1, 2019 and ending December 31, 2021), and (2) the executive remaining an employee or director of ours (including our affiliates) until February 19, 2022.

•

With respect to the Relative TSR Performance RSUs granted in 2019, the number of units that may vest is based upon the Company's TSR performance ranking ("TSR Rank") relative to the companies included in the S&P 500 Index, with the target number of units being earned if the TSR Rank equals the 55^th percentile of the S&P 500 Index. If the TSR Rank equals or exceeds the 90^th percentile of the S&P 500 companies, 150% of the target number of units will be earned, and if the TSR Rank equals the 30^th percentile of the S&P 500 companies, 50% of the target number of units will be earned. For TSR Rank outcomes (a) between the 30^th and 55^th percentiles of the S&P 500 companies or (b) between the 55^th and 90^th percentiles of the S&P 500 companies, the percentage of target units earned will be calculated via linear interpolation. Should the TSR Rank fall below the 30^th percentile of the S&P 500 companies, no Relative TSR Performance RSUs will be earned, and all such awards will be forfeited.

•

With respect to the Absolute TSR Performance RSUs granted in 2019, the number of units that may vest is based upon the Company's Annualized TSR compared to pre-established hurdles, with the target number of units being earned if Annualized TSR equals 11.5%. If Annualized TSR equals or exceeds 16.5%, 150% of the target number of units will be earned, and if Annualized TSR equals 6.5%, 50% of the target number of units will be earned. For Annualized TSR outcomes (a) between 6.5% and 11.5% or (b) between 11.5% and 16.5%, the percentage of target units earned will be calculated via linear interpolation. Should Annualized TSR fall below 6.5%, no Absolute TSR Performance RSUs will be earned, and all such awards will be forfeited.

The table below illustrates the payout range for the Performance RSUs granted in 2019.



Relative TSR Performance RSUs			Absolute TSR Performance RSUs
Performance Level	TSR Rank	Vesting	Performance Level	Annualized TSR	Vesting

Maximum	90th percentile	150%	Maximum	16.5%	150%
Target	55th percentile	100%	Target	11.5%	100%
Threshold	30th percentile	50%	Threshold	6.5%	50%
Below Threshold	<30th percentile	0%	Below Threshold	<6.5%	0%

¹ Because the Committee utilizes a structural valuation prepared by the Compensation Consultant for purposes of determining the number of Performance RSUs to grant to the NEOs, as further described at "—CD&A—Elements of Executive Compensation and Benefits—Long-Term Incentives—RSUs—RSU Valuations and Grant Levels," the grant date fair value of such awards for accounting purposes pursuant to Financial Accounting Standards Board's Accounting Standards Codification Topic 718 ("ASC 718") may vary from the targeted grant mix.

² The Committee has the authority to interpret and determine the application and calculation of matters relating to the determination of TSR, TSR Rank and Annualized TSR and to make adjustments it deems appropriate to reflect changes in the Common Stock, including as a result of any stock split or consolidation, stock dividend, recapitalization, merger, reorganization, or other relevant distribution or change in capitalization.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

The levels at which the TSR Rank and Annualized TSR vesting targets are established are generally reviewed and approved at the First Regular Committee Meeting of the grant year. The review generally includes an analysis of (1) historical Common Stock price performance, (2) our financial forecasts and budgets, and (3) performance contingent equity compensation market practices as disclosed in third-party market sources, which includes consideration of market and industry trends.

Additional information regarding the Performance RSUs described above is provided below in the tables and related footnotes at "—Summary Compensation Table" and "—Grants of Plan-Based Awards in 2019" in this "VIII. Executive Compensation."

RSU Valuations and Grant Levels. In determining RSU valuations and grant levels with respect to Annual RSUs, as with the other components of executive compensation, the Committee targets total direct compensation for our executives at approximately the 50th percentile of market. The Committee, with the assistance of the Compensation Consultant, examines the long-term incentive practices at the Peer Group and other companies reviewed in the Competitive Market Analysis to establish market-based ranges of long-term incentive grant levels for each executive. Long-term incentive grant levels, generally based on our overall financial performance for the prior year and each executive's individual performance and anticipated future role, are then (1) determined and approved by the Committee for the CEO and (2) proposed by the CEO and reviewed and considered for approval by the Committee for each of the other executives. The fair value of the RSUs, as determined by the Compensation Consultant, is then converted into a number of units to be granted to each executive. The valuation methodology used to value the Time RSUs awarded in 2019 is summarized in notes 3 and 13 to our consolidated financial statements in our 2019 Form 10-K. The Committee utilized a structural valuation, as determined by the Compensation Consultant, based on the average closing price of our Common Stock for the 20 trading days ending on the day prior to the start of the performance period, to value the Performance RSUs for purposes of determining the number of units to be granted in 2019.

In addition to considering the valuation of each RSU grant, management and the Committee also consider the overall potential stockholder dilution impact and "burn rate" (i.e., the rate at which awards are granted as a percentage of Common Stock outstanding). Each year, the Committee reviews and recommends to the Board for approval a budgeted grant date value of shares that may be used in connection with the grant of Annual RSUs to the executives and our other eligible employees. This review and recommendation process includes an analysis of potential dilution levels and burn rates resulting from the potential grant of such RSUs as compared to independent third-party surveys and the Peer Group. The Committee and management use this competitive market data regarding dilution levels and burn rates as an additional gauge in making decisions regarding annual grants of long-term equity compensation.

Our stockholder dilution, or "overhang," related to long-term incentive awards outstanding as well as shares reserved for future issuance under the 2013 Plan was approximately 2.2% as of December 31, 2019, and our 2019 burn rate was approximately 0.3%. We believe our stockholder dilution and burn rates are competitively low relative to comparable companies (based upon similar analyses of third-party surveys), as well as our Peer Group.

Other Benefits and Perquisites

In addition to base salary, short-term incentives and long-term incentives, we provide the other benefits outlined below. We believe these other benefits support our overall attraction and retention objectives.

Severance Agreements

The Committee believes establishing competitive severance arrangements with our executives is a key part of a total rewards package to effectively recruit and retain high-performing executives. We have entered into severance agreements containing severance benefits and non-compete and non-solicitation provisions with each of our NEOs and certain other senior officers (as amended, "Severance Agreements"). We do not currently have employment-related agreements with any of our NEOs other than the Severance Agreements.

Pursuant to each Severance Agreement, we are generally required to provide severance benefits to the officer if such officer is terminated without cause (as defined in the Severance Agreement) or such officer terminates employment with Good Reason (as defined in the Severance Agreement) (collectively a "qualifying termination"). The Severance Agreements provide for enhanced severance benefits if the officer incurs a qualifying termination within two years following a Change in Control (as defined in the Severance Agreements).



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

The Committee has adopted a policy not to enter into any agreement providing for an excise tax "gross up" payment relating to an "excess parachute payment" (pursuant to Section 280G of the Internal Revenue Code of 1986, as amended ("Code")) ("Excise Tax Payment"), and no existing Severance Agreements contain Excise Tax Payment provisions.

We periodically review the level of officer severance benefits by analyzing our severance benefits as compared to competitive market severance and change-in-control practices as provided in surveys and information from third parties. Subsequent Severance Agreements may be different as a result of such reviews.

Details regarding the severance benefits provided under the Severance Agreements and the potential value thereof are provided below at "—Potential Payments Upon Termination of Employment" in this "VIII. Executive Compensation."

Extended Service Separation Program

The Board has approved a program designed to make available certain retirement-type benefits to all employees, including the NEOs, that meet certain age and service requirements. Generally, to be eligible, (1) the sum of an employee's age and years of service as an employee must be at least 70, with age and service minimums of 55 years and 10 years, respectively, and (2) the employee must provide us with at least six months' prior notice (or, for certain non-executive positions, three months' prior notice) of his or her intention to terminate employment. Assuming these conditions are satisfied, RSUs held by such employees that were granted at least six months prior to termination will continue to have the opportunity to vest pursuant to their terms (other than the employment requirement), subject to certain additional conditions, including the execution of a full release, an agreement to not compete with us for a period of 12 months and an agreement to be available for consultation with us during such 12-month period. As to an employee not holding RSUs, the program generally provides that, in connection with employment termination, an employee who meets the above eligibility requirements will receive a fully-vested, discretionary, profit-sharing contribution pursuant to the Company's 401(k) Plan equal to 25% of the employee's base salary. The program is subject to interpretation, modification or termination by the Committee or Board in the sole discretion of each at any time.

Retirement Benefits

Our executives are eligible to participate in our 401(k) Plan under the same parameters applicable to all other employees, including eligibility for (1) a base matching contribution equal to 100% of the first 3% of the executive's compensation contributed ("Base Match"), (2) a discretionary annual matching contribution equal to 100% of the next 3% of the executive's compensation contributed ("Discretionary Match") and (3) an additional discretionary profit sharing contribution equal to 4% of the employee's base salary ("Discretionary Contribution"). In each case, the Base Match, the Discretionary Match and the Discretionary Contribution are (1) subject to the Committee's discretion and (2) treated as subject to Internal Revenue Service ("IRS") limitations. The value of our Base Match, Discretionary Match and Discretionary Contribution for each NEO for the applicable 401(k) Plan years are provided below in the table at "—Summary Compensation Table" and "—All Other Compensation Table" in this "VIII. Executive Compensation."

Health and Welfare Benefits

Our executives are eligible to participate in the same health and welfare benefits that are available to our other eligible employees, such as medical (including vision), dental, life and disability insurance. The value of the health and welfare benefits paid by us for each NEO in applicable years is provided below in the tables at "—Summary Compensation Table" and "—All Other Compensation Table" in this "VIII. Executive Compensation."

Relocation Benefits

In general, we do not offer our executives significant perquisites, other than relocation assistance. We generally offer relocation assistance to all of our employees (including our executives) who we ask to relocate in connection with their employment with us, with the level of benefits generally corresponding to the level of the employee's position. We have found that relocation assistance can play an important role in attracting qualified candidates or transferring existing employees to our various office locations. The primary benefits provided under our relocation assistance program to our NEOs and other senior management are generally: reasonable moving and related expenses, closing costs related to selling and buying a house, and temporary living expenses, if needed, for up to 60 days. No relocation benefits were provided to our NEOs in 2019.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Other Matters

Stock Ownership and Retention Guidelines

In order to further align the interests of our senior management with those of our stockholders, we have adopted certain stock ownership and retention guidelines designed to support a culture of ownership among the NEOs and certain other senior officers. The Committee believes the maintenance of stock ownership and retention guidelines motivates executives to perform in accordance with the interests of our stockholders. The guideline ownership levels are designed to ensure that executives have a meaningful economic stake in our Common Stock, while satisfying the executives' need for portfolio diversification. Our stock ownership guidelines generally provide that each of the NEOs should seek to establish and maintain beneficial ownership of a number of shares of Common Stock having a value sufficient to satisfy the applicable stock ownership level specified below:



Name	Title	Multiple of Base Salary(a)
Jay A. Brown	President & CEO	6X
Daniel K. Schlanger	SVP & CFO	3X
James D. Young	SVP & COO—Fiber	3X
Robert C. Ackerman	SVP & COO—Towers & Small Cells	3X
Kenneth J. Simon	SVP & General Counsel	3X


(a)	Represents the dollar value of Common Stock to be held, as determined pursuant to NYSE quotations.

The NEOs generally have until the fifth anniversary of the date such NEO was appointed SVP or higher, to meet the applicable stock ownership level. In addition, an NEO generally has until the fifth anniversary after the date of an increase in base salary to meet the incremental increase to the applicable stock ownership level as a result of such base salary increase. As of the Record Date, each of the NEOs held shares of Common Stock (as calculated pursuant to the stock ownership guidelines) having a value in excess of such NEO's applicable stock ownership level specified by the stock ownership guidelines.

Our retention guidelines provide that if an NEO's Common Stock ownership is below (or subsequently falls below) the applicable stock ownership level, such NEO should generally hold and retain all shares of Common Stock received by the NEO resulting from equity awards granted to the NEO by the Company as a component of compensation until the NEO's applicable stock ownership level is met. The retention guidelines apply with respect to "after-tax shares" (e.g., the sale of shares to cover taxes relating to Company granted equity awards is not subject to the stock ownership guidelines).

Anti-Hedging Policy

Our insider trading policy prohibits our directors and employees, including our executive officers, from, among other things, short sales and trading in options, puts, calls, or other derivative instruments relating to our securities, including for hedging purposes.

Recoupment Policy

Pursuant to our Recoupment Policy, in the event of a restatement of a Company financial statement or a determination by the Board that misconduct by an NEO or certain other employees caused financial or reputational harm to the Company, the Committee will review the circumstances and make recommendations to the Board as to whether recoupment should be pursued. Under the policy, "misconduct" includes any intentional or reckless violation of our guidelines and policies or any grossly negligent act or failure to act causing the above described result. In such circumstances, the Committee will review all compensation that has been awarded to a responsible party and determine how such compensation may have been affected by the financial restatements or misconduct.

Should the Board determine that recoupment is appropriate, we may recoup from an NEO or other responsible employee any cash incentives and equity awarded in reliance on the financial statements that were restated, or for the year in which the financial or reputational harm occurred, to the extent the Committee determines that the cash incentives and equity awarded were based on such restated financial statements or resulted from such misconduct. The NEO and other responsible employees may also be subject to other disciplinary actions, up to and including termination of employment.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Following the Accounting Restatement, the Committee performed an assessment of and reviewed and considered the relevant facts and circumstances, along with input from its independent advisors, as to whether any recoupments were necessary or appropriate in connection with the restatement of previously issued financial statements. The Board, upon recommendation from the Committee, determined that no recoupments were necessary or appropriate under the circumstances.

Accounting and Tax Impacts upon Executive Compensation

For a discussion of the accounting impacts on various elements of long-term incentive compensation, see notes 3 and 13 to our consolidated financial statements in our 2019 Form 10-K.

In determining executive compensation, the Committee considers, among other factors, the possible tax consequences. Tax consequences, including tax deductibility, are subject to factors that are beyond our control. In addition, the Committee believes that it is important to retain flexibility in designing compensation programs that meet its stated objectives. For these reasons, the Committee, while considering tax deductibility as one of the factors in determining compensation, has historically not limited compensation to those levels or types of compensation that will be deductible by us.

Section 162(m) of the Code, as amended by the Tax Cuts and Jobs Act enacted in December 2017, generally disallows a public company's tax deduction for compensation paid to the CEO and certain of its other executive officers in excess of $1 million in any taxable year. Because we intend to continue to qualify as a REIT under the Code, we generally distribute a sufficient level of net taxable income to our stockholders on an annual basis, and as a result, do not incur U.S. federal income tax.

Potential Payments Upon Termination of Employment

Severance Agreements

We have entered into Severance Agreements with each of our NEOs, which provide certain benefits to and impose certain obligations on our NEOs upon termination of their employment with us. Details regarding the benefits provided under the NEOs' Severance Agreements and the potential value thereof are set forth below. Pursuant to each Severance Agreement, we are required to provide severance benefits to the NEO if such NEO's employment is terminated pursuant to a Qualifying Termination (as defined in footnote (a) to the table below). The Severance Agreements provide for enhanced severance benefits if the NEO's employment is terminated in connection with a Qualifying Termination Upon Change in Control (as defined in footnote (a) to the table below).

Upon a Qualifying Termination occurring on December 31, 2019 not during a Change in Control Period (as defined in the Severance Agreements), the NEOs would have been entitled to the following benefits:


•	a lump sum severance payment equal to the sum of the officer's base salary and Annual Bonus. "Annual Bonus" is defined for purposes of each NEO's Severance Agreement as the target annual bonus for the calendar year in which the date of termination occurs;


•	a prorated cash amount equal to the officer's Annual Bonus for the year in which termination occurs when and if annual incentives for the year of termination are paid to other executive officers;


•	to the extent the annual incentive for the year prior to the year in which termination occurs has not been paid, a cash amount equal to the officer's prior year actual annual incentive when and if any annual incentives for the year prior to the date of termination are paid to our other executive officers;


•	continued coverage under specified health and welfare benefit programs for one year;


•	continued participation in the 401(k) Plan for the calendar year in which termination occurs, including our contributions based upon participation or matching (with payment of the after-tax economic equivalent if and to the extent such is not permitted under the 401(k) Plan or by applicable law); and


•	immediate vesting of all stock options and continued vesting of all Restricted Stock Awards (as defined in the Severance Agreements) (including RSUs)³ for two years after termination.

In connection with a Qualifying Termination Upon Change in Control occurring on December 31, 2019, the NEOs would have been entitled to the following benefits:


•	a lump sum severance payment equal to the sum of the officer's base salary and Annual Bonus multiplied by two;


•	a prorated cash amount equal to the officer's Annual Bonus for the year in which termination occurs when and if annual incentives for the year of termination are paid to other executive officers;


•	to the extent the annual incentive for the year prior to the year in which termination occurs has not been paid, a cash amount equal to the officer's prior year actual annual incentive when and if any annual incentives for the year prior to the date of termination are paid to our other executive officers;


•	continued coverage under specified health and welfare benefit programs for two years;


•	continued participation in the 401(k) Plan for the calendar year in which termination occurs, including our contributions based upon participation or matching (with payment of the after-tax economic equivalent if and to the extent such is not permitted under the 401(k) Plan or by applicable law); and

•

immediate vesting of any outstanding Restricted Stock Awards, RSUs and stock options held by the officer, provided that such immediate vesting only applies to Performance Awards (as defined in the Severance Agreements) with respect to the target shares or Target Level of performance, and the officer continues to vest as to any Performance Awards in excess of such target shares or Target Level of performance following the date of termination.

Each of the Severance Agreements also has provisions that generally prohibit the officer, for a period of 12 months following the termination of such officer's employment with us, from (1) engaging in business activities relating to wireless communication or broadcast towers which compete with us or our affiliates in the United States or Australia and (2) soliciting our employees and our affiliates.

	Non-Qualifying	—	—	—	—


(a)	Represents the various employment termination scenarios as defined in the NEO's Severance Agreements. Generally, each of the scenarios can be described as follows:


•	A "Qualifying Termination" occurs upon (1) our termination of the executive's employment with us for any reason other than for Cause (as defined in the Severance Agreements) or disability or death, or (2) the executive's termination of employment with us within 60 days of the occurrence of an event that constitutes Good Reason (as defined in the Severance Agreements).


•	A "Non-Qualifying Termination" occurs upon any termination of the executive's employment with us other than a Qualifying Termination.


•	A "Qualifying Termination Upon Change in Control" occurs upon a Qualifying Termination of the executive within two years following a Change in Control (as defined in the Severance Agreements).


(b)	Represents the lump sum severance payment equal to the sum of the NEO's base salary and Annual Bonus multiplied by two and one for a Qualifying Termination Upon Change in Control and Qualifying Termination, respectively.

(c)

Represents the value of outstanding and unvested RSUs as of December 31, 2019 (calculated as the number of RSUs multiplied by $142.15, the closing price per share of our Common Stock on December 31, 2019) for which the vesting would be accelerated or continued without future service or performance conditions (also includes accrued dividend equivalents that would be paid upon vesting of such RSUs). Upon a Qualifying Termination Upon Change in Control, any outstanding Restricted Stock Awards (as defined in the Severance Agreements), RSUs and stock options held by the NEO immediately vest, provided that such immediate vesting only applies to Performance Awards with respect to the target shares or Target Level of performance, and the officer may, subject to and contingent upon actual performance, continue to vest as to any Performance Awards in excess of such target shares or Target Level of performance following the date of termination. Upon a Qualifying Termination that does not occur during a Change in Control Period, any outstanding Restricted Stock Awards and RSUs will continue to vest, provided that (1) such continued vesting of Performance Awards will continue to be contingent on the satisfaction of the applicable performance criteria and (2) such continued vesting of Restricted Stock Awards and RSUs terminates upon the second anniversary of such Qualifying Termination.


(d)	Other termination benefits represent the following items:

•

A prorated cash amount equal to the officer's Annual Bonus for the year of termination. The payment of a cash amount equal to the NEO's prior year annual incentive when and if any annual incentives for the year prior to the date of termination are paid to our other executive officers is permitted under the Severance Agreements but would not apply under this scenario because termination is assumed to occur as of December 31, 2019, and any prior year actual annual incentives relating to 2018 would have already been paid.


•	An estimate of the premiums paid by us for continued coverage under specified health and welfare benefit programs.


•	An estimate of our 401(k) Plan matching and profit sharing contributions for continued participation in the 401(k) Plan for 2019, the year in which termination of employment is assumed to occur under this scenario. Assuming termination of employment occurs on December 31,



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

2019, this amount includes our Discretionary Match and Discretionary Contribution for 2019. The Discretionary Match and the Discretionary Contribution are subject to compensation limitations of the Code; for each NEO, the amounts included above are $8,400 for the Discretionary Match and $11,200 for the Discretionary Contribution.


(e)	Represents an estimate of the total potential payments upon termination of employment that would be paid to or accrued for each NEO assuming the respective NEO's employment terminated as of December 31, 2019 under the scenarios set forth in the table.

CEO Pay Ratio

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Item 402(u) of Regulation S-K promulgated thereunder and the related SEC guidance ("Pay Ratio Rules"), we are providing the following information about the relationship of the annual total compensation of our median employee to the annual total compensation of our CEO. We believe that the pay ratio disclosed below is a reasonable estimate calculated in a manner consistent with the Pay Ratio Rules. Due to estimates and assumptions permitted under the Pay Ratio Rules, our pay ratio disclosure may not be comparable to the pay ratio disclosure presented by other companies.

CEO Pay Ratio Methodology

As permitted under SEC rules, we are using the same median employee for our 2019 CEO pay ratio disclosure as identified for purposes of our 2018 CEO pay ratio disclosure. We believe it is reasonable to use the same median employee for purposes of calculating the pay ratio disclosure because we did not experience material changes in 2019 to our employee population or compensation arrangements that would significantly affect our pay ratio disclosure. For purposes of identifying our median employee in 2018, we took the following steps:


•	We determined that as of December 31, 2018 ("Determination Date"), our employee population, excluding our CEO, consisted of approximately 5,000 employees, including full-time employees, part-time employees and interns. No employees were excluded on the basis of geography.

•

For each employee, we calculated on a consistent basis (a) the base salary in effect as of the Determination Date, (b) the annual incentive paid with respect to fiscal year 2018, (c) commissions paid during fiscal year 2018 and (d) the grant date fair value of RSUs granted during fiscal year 2018 (calculated in accordance with ASC 718). For each employee, the sum of these components of compensation was then analyzed and sorted to identify the median employee.

Once the median employee was identified, the median employee's annualized total compensation shown in the chart above was calculated using the same methodology that we used to calculate the CEO's annual total compensation as reported in the Summary Compensation Table (see "VIII. Executive Compensation—Summary Compensation Table") included in this Proxy Statement.

IX. AUDIT COMMITTEE MATTERS

The Board has established an Audit Committee comprised entirely of independent directors, as defined in the rules and regulations of the NYSE and SEC. Upon the recommendation of the Audit Committee and in compliance with the regulations of the NYSE, the Board has adopted an Audit Committee Charter setting forth the requirements for the composition of the Audit Committee, the qualifications of its members and the responsibilities of the Audit Committee. The Audit Committee Charter can be found under the Investors section of our website at https://www.crowncastle.com/investors/corporate-governance.

The Audit Committee has adopted procedures regarding the pre-approval of certain services which may be rendered by our Auditors. Such procedures provide that the Audit Committee should pre-approve audit and permitted non-audit services to be rendered by our Auditors. Such approval of services may be made with respect to audit, audit-related, tax and other services permitted under SEC rules that the Audit Committee believes would not otherwise impair the independence of the Auditors. Whenever practicable, estimated or budgeted fees should be pre-approved at the time the services are pre-approved. Such procedures also provide that between the regularly scheduled meetings of the Audit Committee, each member of the Audit Committee (with preference given to the Chairman of the Audit Committee, if available) is authorized to pre-approve fees or engagements presented by an officer relating to audit and permitted non-audit related services of our independent registered public accountants; provided, however, the Audit Committee members in the aggregate may not approve fees and engagements exceeding $200,000 of fees, excluding any fees or engagements (1) approved by the Audit Committee or (2) regarding services relating to securities offerings of the Company and its subsidiaries ("Delegation Procedures"). At the regularly scheduled meetings of the Audit Committee, the Audit Committee is generally provided a schedule detailing any services which have been approved or utilized during the fiscal year and since the last regularly scheduled Audit Committee meeting, including any fees and engagements approved pursuant to the Delegation Procedures.

No services were provided by the independent registered public accountants in 2019 that were approved by the Audit Committee under SEC Regulation S-X Section 2-01(c)(7)(i)(C) (which addresses certain services considered de minimus approved by the Audit Committee after such services have been performed).

In addition, in accordance with regulations promulgated by the SEC, the Audit Committee has issued the following report.

Audit Committee 2019 Report

To our Stockholders:

Management of Company has the primary responsibility for preparing the Company's financial statements and implementing the Company's reporting process, including the Company's system of internal controls. The Company's independent registered public accountants are responsible for expressing an opinion on (1) the conformity of the Company's audited financial statements with accounting principles generally accepted in the United States and (2) the effectiveness of internal control over financial reporting. On behalf of the Board, the Audit Committee, among other functions, performs an oversight role relating to the Company's financial statements and accounting practices, systems of internal control, the independence and the performance of the independent registered public accountants, and the performance of the internal audit function.

In this context, the Audit Committee hereby reports as follows:


•	The Audit Committee has reviewed and discussed with the Company's management the audited financial statements as of and for the year ended December 31, 2019.


•	PwC represented that its presentations included the matters required to be discussed with the Audit Committee by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC.


•	The Audit Committee has received the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding PwC's communications with the Audit Committee concerning independence, and has discussed with PwC its independence.



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT


•	Based on its review of the Company's audited financial statements and the discussions with management and PwC referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the 2019 Form 10-K.

Respectfully submitted by the Audit Committee of the Board.

X. OTHER MATTERS

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with the SEC and the NYSE reports of ownership and changes in ownership of Common Stock and our other equity securities.

Based solely on the review of such reports filed with the SEC and written representations that no other reports were required, we believe that, during the 2019 fiscal year, our executive officers, directors and greater than 10% beneficial owners timely complied with all Section 16(a) filing requirements applicable to them, except that Mr. Ackerman did not timely file one report with respect to one transaction.

Stockholder Recommendation of Director Candidates

Stockholders may recommend potential candidates for consideration by the NCG Committee by sending a written request to our Corporate Secretary. The written request must include the candidate's name, contact information, biographical information and qualifications.

CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

Appendix A

Independence Categorical Standards

(February 21, 2018)

The board of directors (“Board”) of Crown Castle International Corp. (“Company”) has established the following guidelines to assist it in determining whether a director of the Company (“Director”) has a “material relationship” with the Company and is “independent”.

The following relationships are not “material relationships” that would impair a Director’s “independence” (“Safe Harbor Relationships”):


•	Certain Prior Relationships. More than three years have elapsed since:


a)	the Director was employed by the Company;


b)	a Family Member (defined below) was employed by the Company as an executive officer;


c)	the Director or a Family Member (in a professional capacity) was a partner with or employed by the Company’s internal or external auditor (“Auditor”) and personally worked on the Company’s audit; or


d)	a present executive officer of the Company served on the compensation committee of a company which employed at the same time the Director or a Family Member as an executive officer.


•	Current Employment. A Family Member is:


a)	employed by the Company in a non-officer position; or


b)	employed by, but is not a partner with, the Auditor and does not personally work on the Company’s audit.


•	Compensation. The Director or a Family Member has received less than $120,000 during any 12-month period in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).


•	Business Relationships. The Director or a Family Member is or was a partner, greater than 10% shareholder, director, officer or employee of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, is less than the greater of:


a)	$1 million, or


b)	two percent (2%) of such other company’s consolidated gross revenues.


•	Indebtedness. The Director or a Family Member is a partner, greater than 10% shareholder, director, officer or employee of a company that is indebted to the Company or to which the Company is indebted, and the total amount of each company’s indebtedness to the other is less than two percent (2%) of the total consolidated assets of such other company.


•	Charitable Contributions. The Director or a Family Member is a trustee, fiduciary, director, officer or employee of a tax-exempt organization to which the Company contributes, and the Company’s contributions in any single fiscal year to that organization are less than the greater of:


a)	$500,000, or


b)	one percent (1%) of that organization’s total annual receipts.


•	Stock Ownership. The Director owns, directly or indirectly, a significant amount of Company stock (including securities convertible into Company stock).

A “Family Member” is a Director’s spouse, parents, children, siblings, mother- and father-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and anyone (other than domestic employees) who shares such Director’s home.

If a Director has a significant relationship with the Company that does not constitute a Safe Harbor Relationship, the determination of whether such relationship constitutes a “material relationship”, and therefore whether the director qualifies as independent, should be made by the Board based on the totality of circumstances. In addition, members of the Audit Committee are subject to additional standards relating to their independence.

Appendix B

Non-GAAP Financial Measures

This Proxy Statement includes presentations of Adjusted EBITDA, Adjusted Funds from Operations ("AFFO"), including per share amounts, and Funds from Operations ("FFO"), which are non-GAAP financial measures. These non-GAAP financial measures are not intended as alternative measures of operating results or cash flow from operations (as determined in accordance with Generally Accepted Accounting Principles ("GAAP")).

Our non-GAAP financial measures are presented as additional information because management believes these measures are useful indicators of the financial performance of our business. Among other things, management believes that:

•

Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance. Adjusted EBITDA is the primary measure used by management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations. Management believes that Adjusted EBITDA helps investors or other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors, by removing the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results. Management also believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of the communications infrastructure sector and other REITs to measure financial performance without regard to items such as depreciation, amortization and accretion which can vary depending upon accounting methods and the book value of assets. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used in our debt covenant calculations. Adjusted EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

•

AFFO, including per share amounts, is useful to investors or other interested parties in evaluating our financial performance. Management believes that AFFO helps investors or other interested parties meaningfully evaluate our financial performance as it includes (1) the impact of our capital structure (primarily interest expense on our outstanding debt and dividends on our preferred stock) and (2) sustaining capital expenditures, and excludes the impact of our (a) asset base (primarily depreciation, amortization and accretion) and (b) certain non-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods. GAAP requires rental revenues and expenses related to leases that contain specified rental increases over the life of the lease to be recognized evenly over the life of the lease. In accordance with GAAP, if payment terms call for fixed escalations, or rent free periods, the revenue or expense is recognized on a straight-lined basis over the fixed, non-cancelable term of the contract. Management notes that Crown Castle uses AFFO only as a performance measure. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows from operations or as residual cash flow available for discretionary investment.

•

FFO is useful to investors or other interested parties in evaluating our financial performance. Management believes that FFO may be used by investors or other interested parties as a basis to compare our financial performance with that of other REITs. FFO helps investors or other interested parties meaningfully evaluate financial performance by excluding the impact of our asset base (primarily depreciation, amortization and accretion). FFO is not a key performance indicator used by Crown Castle. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flow from operations.

We define our non-GAAP financial measures as follows:

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) plus restructuring charges (credits), asset write-down charges, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other (income) expense,



CROWN CASTLE INTERNATIONAL CORP.		2020 PROXY STATEMENT

B - 1

(benefit) provision for income taxes, cumulative effect of a change in accounting principle, (income) loss from discontinued operations and stock-based compensation expense.

AFFO. We define AFFO as FFO before straight-lined revenue, straightlined expense, stock-based compensation expense, non-cash portion of tax provision, non-real estate related depreciation, amortization and accretion, amortization of non-cash interest expense, other (income) expense, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, acquisition and integration costs, and adjustments for noncontrolling interests, and less sustaining capital expenditures.

AFFO per share. We define AFFO per share as AFFO divided by diluted weighted-average common shares outstanding

FFO. We define FFO as net income plus real estate related depreciation, amortization and accretion and asset write-down charges, less noncontrolling interest and cash paid for preferred stock dividends, and is a measure of funds from operations attributable to CCIC common stockholders.
