CROWN CASTLE INTERNATIONAL CORP.		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.”).

I. INFORMATION ABOUT VOTING

Solicitation of Proxies. The Board of Directors (“Board”) of Crown Castle International Corp. is soliciting proxies for use at our 2016 Annual Meeting of Stockholders (“Annual Meeting”) and any adjournments or postponements of the Annual Meeting. The Annual Meeting will be held on May 19, 2016 at 9:00 a.m. Central Time at our offices located at 1220 Augusta Drive, Suite 600, Houston, Texas 77057. This Proxy Statement, the form of proxy and our Annual Report on Form 10-K for the year ended December 31, 2015 (“ 2015 Form 10-K”) are being distributed or made available via the Internet to our stockholders on or about April 4, 2016 .

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 and 2015 Form 10-K 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 April 4, 2016 , we intend to mail 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 2015 Form 10-K and how to submit a proxy online. If you receive a Proxy Materials Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you request it. Instead, the Proxy Materials Notice instructs you on how to access and review all of the important information contained in the Proxy Statement and 2015 Form 10-K. The Proxy Materials Notice also instructs you on how you may submit your proxy over the Internet. If you received a Proxy Materials Notice by mail and 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 2016 ;


•	a non-binding, advisory vote regarding 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, 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 28, 2016 (“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 337,559,718 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 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 the toll-free telephone number shown at the website address listed on your Proxy Materials Notice or on your proxy card; or


•	visit the website shown on your Proxy Materials Notice or the proxy card to submit a proxy via the Internet.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

Alternatively, you may vote in person 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 or proxy card in front of you when submitting a proxy by telephone or the Internet; it contains important information that is required to access the system.

Use of Proxies. All proxies that have been 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 2016 (Proposal 2); and


•	FOR the non-binding, advisory vote regarding 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. At 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 revoke your proxy at any time before it is exercised. You can revoke a 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 in person (see “—How to Vote” above and “—Annual Meeting Admission” below in this “I. Information About Voting” regarding voting at the meeting if your shares are held in the name of a bank, broker or other nominee). Attendance at the meeting alone will not constitute a revocation of a proxy.

The 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 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 2016 (Proposal 2) and (2) the non-binding, advisory resolution regarding 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.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

Annual Meeting Admission. 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 “I. 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 meeting in person, 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.		PROXY STATEMENT

II. PROPOSALS

1. Election of Directors

Pursuant to our Restated Certificate of Incorporation (“Charter”), we have been in the process of declassifying the Board and moving to annual elections of directors. This process has resulted in the Board being fully declassified (and all Board members standing for annual elections) commencing with this Annual Meeting. Beginning with the election of directors at the Annual Meeting, all directors (other than any director who may be elected by the holders of any series of preferred stock) shall 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 Board is currently comprised of 12 directors. John P. Kelly (our former CEO and a non-independent director) will retire from the Board effective upon the expiration of his current term as a director at the Annual Meeting, and Jay A. Brown has been nominated as an initial director nominee to the Board. Immediately following the Annual Meeting, if all 12 director nominees are elected, the Board will continue to consist of 12 directors.

The nominees for director at the Annual Meeting are: P. Robert Bartolo, Jay A. Brown, Cindy Christy, Ari Q. Fitzgerald, Robert E. Garrison II, Dale N. Hatfield, Lee W. Hogan, Edward C. Hutcheson, Jr., J. Landis Martin, Robert F. McKenzie, Anthony J. Melone and W. Benjamin Moreland. Each of these nominees, other than Jay A. Brown, 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 section of this Proxy Statement (see “III. 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.		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 2016 . 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 2016 .

We were billed for professional services provided with respect to fiscal years 2015 and 2014 by PwC in the amounts set forth in the following table.



Services Provided	2015		2014
Audit Fees (a)	$	2,320,298	$	1,914,000
Audit-Related Fees (b)	883,846		14,000
Tax Fees (c)	229,713		195,000
All Other Fees (d)	—		—
Total	$	3,443,857	$	2,123,000

(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 2015 were for services in connection with agreed upon procedures for a securitized debt offering and assistance with financial due diligence. Audit-related fees for 2014 were for services in connection with audits of employee benefit plans and fees for assistance with financial due diligence.


(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 2016 .



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

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

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010 (“Dodd-Frank Act”), requires that we provide our stockholders with 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 compensation disclosure rules of the SEC.

Accordingly, we are asking our stockholders to vote on 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 2016 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 “VII. 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 and operating goals and total stockholder return relative to a peer group of companies, 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.

IV. INFORMATION ABOUT THE BOARD OF DIRECTORS

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 2015 , the Board held eight meetings (four regularly scheduled and four special). Each incumbent director attended at least 75% of the aggregate of (1) the total number of meetings of the Board during the period 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 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. All 11 of the directors serving on the Board at the time of our 2015 annual meeting of stockholders (“ 2015 Annual Meeting”) attended the 2015 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 has provided periodic updates (generally quarterly) to the Audit Committee with respect to the Internal Audit department’s activities, including with respect to risk management matters 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.

Board Committees

The Board has four standing Committees: Audit Committee, Compensation Committee, NCG Committee and Strategy Committee. Copies of the Committee charters of each of the Audit Committee, Compensation Committee and the NCG Committee can be found under the Investor Relations section of our website at http://www.crowncastle.com/investor/corpgovernance.asp , and such information is also available in print to any stockholder who requests it through our Corporate Secretary. A summary of each standing Committee’s function is set forth below.

•	Nominating & Corporate Governance Committee

Members: Ms. Christy (Chair), Mr. Hatfield, Mr. Martin and Mr. Melone—all independent directors, as defined under NYSE listing standards.

Number of Meetings in 2015 : 4

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

•	recommend to the Board director nominees for each Committee of the Board;

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

Board Compensation Process and Procedures: The NCG Committee reviews the compensation arrangement for the non-employee directors of the Board on a periodic basis. In the fourth quarter of each of 2014 and 2015 , the NCG Committee, with the assistance of the Compensation Consultant, reviewed the Board’s non-employee director compensation arrangement. The NCG Committee reviewed a competitive market analysis prepared by the Compensation Consultant comparing the Board’s compensation arrangement to those of the companies comprising our Peer Group (as defined in “VII. Executive Compensation—Compensation Discussion and Analysis” below) and a sample of public general industry companies (derived from third-party proprietary compensation surveys). Based on the results of the competitive market analysis reviews, (1) in the fourth quarter of 2014, the NCG Committee determined and the Board ratified that no changes be made to the compensation program for non-employee directors at such time and (2) in the fourth quarter of 2015, the NCG Committee determined and the Board ratified that the Annual Equity Grant (defined below) be increased to $155,000, with an additional $75,000 equity award amount for a non-employee Chairman of the Board (i.e., an aggregate $230,000 Annual Equity Grant for a non-employee Chairman of the Board), with the other components of non-employee director compensation left unchanged. The components of the Board compensation arrangement for non-employee directors for 2015 are described below at “—Board Compensation” in this “IV. Information About the Board of Directors.”

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 later of (1) March 25, 2018 or (2) the fifth anniversary of the date such director is appointed to the Board, ¹ 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) for non-employee directors (currently $155,000). Common Stock retention guidelines for non-employee directors are substantially similar to those applicable to our executives as described in “VII. 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

CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

entirety of each candidate’s credentials and 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 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 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.

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 “IX. 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 or not. However, in evaluating a candidate’s relevant experience, the NCG Committee may consider previous experience as a member of the Board.


•	Strategy Committee

Members : Mr. Hatfield (Chair), Ms. Christy, Mr. Fitzgerald, Mr. Hogan, Mr. Hutcheson, Mr. Kelly, Mr. McKenzie and Mr. Melone—all independent directors, except Mr. Kelly.

Number of Meetings in 2015 : 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. Moreland (our current President and CEO) and Mr. Brown (director nominee, and our current SVP, CFO and Treasurer), has no material relationship with us and is an independent director, as defined under 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 and the transaction described in “IV. Information About the Board of Directors—Certain Relationships and Related Transactions—Bayou Commercial, LLC Transaction” of our Proxy Statement relating to the 2014 Annual Meeting (as filed with the SEC on April 7, 2014), which disclosure relating to the Bayou Commercial, LLC Transaction is incorporated herein by reference.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee during fiscal 2015 or as of the date of this Proxy Statement is or has been one of our officers or employees. In addition, during 2015 , 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.		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

General . The Board maintains a compensation arrangement for the non-employee directors of the Board. A director who is also an employee of ours receives no additional compensation for services as a director. For 2015 , 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. In 2015, Mr. Melone received an Initial Equity Grant of 1,104 shares (based upon the closing price of the Common Stock of $81.55 per share on May 29, 2015).

•

Annual Equity Grant. At the Board’s first regularly scheduled meeting of each year, each non-employee director is typically granted shares of Common Stock. For 2015 , the valuation of the Common Stock grant was equal to approximately $125,000 ( $200,000 in the case of the Chairman of the Board), based upon the per share closing price of the Common Stock as of the date of such Board meeting (“Annual Equity Grant”).

Pursuant to the foregoing, on February 12, 2015 , each non-employee director of the Board, other than J. Landis Martin, was granted, pursuant to the 2013 Plan, 1,427 shares of Common Stock (based upon the closing price of the Common Stock of $87.59 per share on February 12, 2015 ). Mr. Martin received a grant of 2,283 shares of Common Stock for service as non-employee Chairman of the Board (based upon the closing Common Stock price of $87.59 per share). As noted above, in the fourth quarter of 2015, the Board approved increasing the value of the Annual Equity Grant to $155,000 ($230,000 in the case of the Chairman of the Board).

•

Retainers. Each non-employee director received an annual retainer of $75,000 for 2015 paid quarterly (“Board Retainer”). In addition, for 2015 (1) the chair of the Audit Committee received an additional $20,000 paid quarterly, the chair of the Compensation Committee received an additional $15,000 paid quarterly, and the chairs of the NCG Committee and Strategy Committee each received an additional $10,000 paid quarterly



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

(collectively, “Committee Chair Retainer”) and (2) each member of the Audit Committee, other than the chair of the Audit Committee, received an additional $5,000 paid quarterly (“Audit Committee Member Retainer”).


•	Other Compensation. Each non-employee director is eligible to participate, at such director’s election, in our medical and dental plans.


•	Expense Reimbursement and Continuing Education. In addition to the foregoing, non-employee directors are reimbursed for reasonable expenses (1) incidental to service on the Board and (2) related to continuing education activities regarding corporate governance, director roles and responsibilities and other matters relating to director duties.

VII. 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 future individual and 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 2015 , as well as the other named executive officers included in the table below at “—Summary Compensation Table” in this “VII. Executive Compensation” are referred to as “NEOs.”

2015 Executive Summary

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. 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 and operating goals and total stockholder return relative to a peer group of companies (“Relative 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 annual incentive awards (“Annual Incentives”), for the achievement of one or more financial and operating performance measures and key individual performance objectives specific to each executive. For 2015 , as a result of generally exceeding the financial performance measures and individual performance objectives, the Annual Incentives awarded pursuant to our 2015 Executive Management Team Annual Incentive Plan were above target. Details regarding Annual Incentives for our executives are provided at “—Elements of Executive Compensation and Benefits—Short-Term Incentives” in this CD&A.

For 2015 , 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 Relative TSR (together with a time vesting criteria) ("Performance RSUs"). 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.

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. See “—Other Matters—Stock Ownership and Retention Guidelines” in this CD&A for additional details regarding our stock ownership and retention guidelines.

We have also adopted a recoupment policy which applies to our NEOs in the event of a financial restatement or a determination by the Board that misconduct by an NEO caused financial or reputational harm to Crown Castle International Corp. See “—Other Matters—Recoupment Policy” in this CD&A for additional details regarding the recoupment policy.

Other notable highlights of our executive compensation program include:


•	The Compensation Committee (for purposes of this CD&A, “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.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT


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


•	We offer no employment agreements with executives.


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


•	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 were removed from all existing severance agreements in 2014.


•	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.

At the 2015 Annual Meeting, we submitted our executive compensation program to an advisory stockholder vote. The stockholders overwhelmingly approved our executive compensation program, with 99.07% 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 2015 Annual Meeting). The Committee has interpreted this vote to mean that our stockholders are supportive of our executive compensation philosophy and program and thus did not enact any significant changes to the 2016 executive compensation program in response to this vote.

In January 2016, the Board approved the CEO Succession Plan pursuant to which, effective June 1, 2016, Mr. Moreland will assume the office of Executive Vice Chairman (an executive officer position), and Mr. Brown will succeed Mr. Moreland as our President and Chief Executive Officer. In addition, in March 2016, we announced that Mr. Daniel K. Schlanger would join us in April 2016 and assume the office of SVP and CFO effective June 1, 2016.

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


•	vacation


•	Learning and development:


•	training


•	succession planning


•	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 and operating results and Relative 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-



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

based and other compensatory 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.

In performing its duties, the Committee obtains input, as it deems appropriate, from the Compensation Consultant, 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 and operating performance, individual 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’ 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 the following:

•

Peer Group Data . Each year the Committee considers public companies in the wireless 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. The Peer Group companies used in the Competitive Market Analysis for gauging the elements of executives’ 2015 compensation were:



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT



• American Tower Corporation	• NetApp, Inc.
• Boston Properties, Inc.	• Prologis, Inc.
• Equinix, Inc.	• SBA Communications Corporation
• F5 Networks, Inc.	• Simon Property Group, Inc.
• Frontier Communications Corporation	• United States Cellular Corporation
• General Growth Properties, Inc.	• Ventas, Inc.
• HCP, Inc.	• Vornado Realty Trust
• Juniper Networks, Inc.	• Welltower, Inc. (formerly Health Care REIT, Inc.)
• Lamar Advertising Company	• Windstream Holdings, Inc.

•

General Industry Market Data . General industry market data (sized appropriately using regression analysis) from a third-party proprietary compensation survey (Towers Watson), 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 telecommunications and REIT industries (e.g., a financial executive with cross-industry skills may be recruited from another industry).

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;


•	other benefits, including retirement benefits and 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’



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

interests with those of our stockholders. The following chart shows the approximate allocation of actual base salary, Annual Incentives and RSUs for 2015 (as shown in “—Summary Compensation Table” in this “VII. Executive Compensation”) among fixed, short-term variable and long-term variable compensation for our NEOs:

2015 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 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 helps us achieve our overall total rewards strategy and 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 target base salary



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

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.

The Committee bases its decisions regarding annual base salary adjustments on multiple factors, including the following:


•	the performance of the executive, including such executive’s contribution, accountability and experience;


•	the executive’s existing base salary as compared to the Competitive Market Analysis; and


•	the annual cost of labor adjustment as provided in various proprietary surveys.

The Committee reviews proposals made by the CEO with regard to base salary adjustments for executives other than himself and then either approves or revises these base salary adjustments. The Committee independently reviews the performance of the CEO and determines and approves an appropriate base salary adjustment for the CEO. For 2015 , Mr. Moreland received a 3.0% annual increase to base salary, while Messrs. Brown, Young, Hawk and Slowey received annual increases to base salary of 6.0%, 6.1%, 6.3% and 6.5%, respectively, to better align their 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 for our executives. Short-term incentives are a variable element of compensation that are generally linked to specific short-term financial, operating and individual performance objectives.

Our short-term incentives are generally “at risk,” meaning they are earned based upon meeting certain performance goals and increase or decrease in value 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 individual and corporate performance based on our goals and objectives;


•	focus business unit executives on maximizing results of their operating segments, while reinforcing the importance of company-wide teamwork;


•	link the financial measures with stockholder expectations; and


•	link the financial and non-financial measures with the individual performance of the executives.

Annual Incentive Awards

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 Executive Management Team Annual Incentive Plan (“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 (“AIP Year End”) of the applicable calendar year.

AIP Award Opportunity . Under the AIP, each executive has minimum, threshold, target and maximum Annual Incentive award opportunities that are aligned with minimum, 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.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

Each corporate and business unit operating executive (i.e., those with direct profit and loss or overall financial responsibilities) is eligible to earn between 0% and 175% of such executive’s target opportunity under the AIP. Each functional executive (i.e., those with indirect profit and loss responsibilities) is eligible to earn between 0% and 150% of such executive’s target opportunity. To mitigate excessive risk, Annual Incentive awards 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 review of total compensation previously discussed. The following table and graph illustrate the 2015 Annual Incentive award opportunities and actual awards as a percentage of base salary for each of the NEOs.



		Percentage of Base Salary
Name	Title	Minimum	Threshold	Target	Maximum	Actual
W. Benjamin Moreland	President & CEO	0.0%	75.0%	150.0%	262.50%	206.6%
Jay A. Brown	SVP, CFO & Treasurer	0.0%	50.0%	100.0%	175.00%	137.7%

Patrick Slowey	SVP & CCO	0.0%	42.5%	85.0%	148.75%	131.4%

Annual Incentive Performance Goals . For 2015 , as in other recent years, there were two categories of performance goals under the AIP: (1) corporate/business unit performance goals and (2) individual performance goals:


•	Corporate/Business Unit Performance Goals . The 2015 corporate/business unit performance goals for our executive officers included the following:


•	Corporate Adjusted EBITDA



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT


•	Corporate Adjusted Funds From Operations (“AFFO”) per Share


•	Business Unit Net New Sales

All of the performance goals were approved by the Committee at the First Regular Committee Meeting of 2015. For each executive, multiple financial performance measures are used; the weight assigned to each corporate/business unit performance goal is reflective of each executive's ability to influence achievement of such goal. For 2015 , as in other recent years, the type and level at which corporate/business unit performance goals are established is primarily based on the Board approved financial budget and the guidance provided to investors for the applicable calendar year, with “target” goals representing the Board approved budget amounts.

The following table lists the 2015 corporate/business unit performance goals used in connection with determining the NEOs’ 2015 Annual Incentive awards (with respect to the position held by the NEO during 2015 ).

•

Individual Performance Goals . Individual performance goals are generally based on the key individual goals approved by the Committee pursuant to our current annual performance management system (our system for documenting and measuring the individual performance of our employees on an annual basis). These goals may include additional financial, operating or qualitative measures for a specific executive and are generally based on the prospective business environment considerations for the upcoming year. The individual performance assessments are based on how well the executive meets the goals established. The following categories are used to assess individual performance:


•	Exceeds Expectations


•	Meets Plus Expectations


•	Meets Expectations


•	Meets Most Expectations


•	Does Not Meet Expectations



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

The mix of corporate/business unit and individual performance goal weightings for each NEO for 2015 were as follows:

NEO Performance Goal Weightings

(a)

For Mr. Moreland, the 2015 individual performance goals include (1) ensure balance sheet flexibility is maintained, while optimizing financial outcome for stockholders; (2) maintain succession plans; (3) assess strategic opportunities and communicate and make recommendations to the Board as appropriate; (4) ensure that we remain properly positioned to integrate new assets; and (5) maintain corporate branding. The Committee approved an “Exceeds Expectations” performance rating with respect to Mr. Moreland’s 2015 individual performance goals.

(b)

For Mr. Brown, the 2015 individual performance goals include (1) ensure timely and accurate compliance with respect to SEC financial reporting and debt reporting requirements; (2) ensure appropriate long-term flexibility of the balance sheet is maintained while optimizing financial outcomes for stockholders; (3) provide internal financial acumen training and development and quarterly reviews of financial results; (4) maintain succession plans; (5) ensure effective management of investor relations; and (6) seek to maximize outcomes regarding discretionary capital allocations. Mr. Moreland proposed and the Committee approved an “Exceeds Expectations” performance rating with respect to Mr. Brown’s 2015 individual performance goals.

(c)

For Mr. Young, the 2015 individual performance goals include (1) meet or exceed 2015 business plan budget; (2) maintain systems and processes to timely meet customer demand; (3) lead effective cross-functional operational relationships to continue to drive automation, consistency and efficiencies; and (4) maintain succession plans. Mr. Moreland proposed and the Committee approved an “Exceeds Expectations” performance rating with respect to Mr. Young’s 2015 individual performance goals.

(d)

For Mr. Hawk, the 2015 individual performance goals include (1) continue to ensure timely and accurate compliance with respect to taxes, corporate maintenance and governance, litigation, securitization, employment and regulatory reporting requirements; (2) continue mitigating tax, legal and regulatory exposure through enhanced planning; (3) provide timely and accurate tax, legal and regulatory support to internal customers; (4) maintain legal team structure with respect to acquisition integration, distributed antenna systems ("DAS") and other services; and (5) maintain succession plans. Mr. Moreland proposed and the Committee approved an “Exceeds Expectations” performance rating with respect to Mr. Hawk’s 2015 individual performance goals.

(e)

For Mr. Slowey, the 2015 individual performance goals include (1) identify and maximize tower leasing opportunities; (2) enhance internal relationships to identify and execute installation services, new tower builds, new DAS builds and rooftop opportunities; (3) develop and maintain strong customer relationships; (4) continue to refine and improve proprietary leasing demand forecasting model; and (5) maintain



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

succession plans. Mr. Moreland proposed and the Committee approved an “Exceeds Expectations” performance rating with respect to Mr. Slowey's 2015 individual performance goals.

We believe this approach to determining financial and individual goals provides the appropriate balance and oversight to our goal-setting process.

Following the AIP Year End, an individual performance rating is (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, based on their performance versus the individual performance goals established at the beginning of the year. An individual payout multiple is then determined based on the individual performance rating as follows (the Committee and the CEO may use positive or negative discretion regarding the exact payout multiples relative to the individual performance ratings):


•	Exceeds Expectations : A corporate and business unit operating executive may earn an individual performance payout multiple of 146% to 175% of target, and a functional executive may earn an individual performance payout multiple of 131% to 150% of target.


•	Meets Plus Expectations : A corporate and business unit operating executive may earn an individual performance payout multiple of 116% to 145% of target, and a functional executive may earn an individual performance payout multiple of 111% to 130% of target.


•	Meets Expectations : A corporate and business unit operating executive may earn an individual performance payout multiple of 90% to 115% of target, and a functional executive may earn an individual performance payout multiple of 90% to 110%.


•	Meets Most Expectations : An executive may earn an individual performance payout multiple of 50% to 89% of target.


•	Does Not Meet Expectations : If an executive is rated “Does Not Meet Expectations,” such executive will not earn or be paid any Annual Incentive.

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


•	A minimum financial performance level of 95% of budgeted Corporate 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, significant deficiency or other material internal control issues may result in a reduction or elimination of Annual Incentives for the responsible executives and potentially all of the executives.

For 2015 , each NEO received an Annual Incentive based on the following applicable total payout multiples of target, all of which fall within the payout multiple parameters described above:



Name	Title	Corporate/Business Unit Performance Goals	Individual Performance Goals	Total
W. Benjamin Moreland	President & CEO	127%	170%	138%
Jay A. Brown	SVP, CFO & Treasurer	127%	170%	138%
James D. Young	SVP & COO	127%	170%	138%
E. Blake Hawk	Former EVP & General Counsel	119%	140%	129%
Patrick Slowey	SVP & CCO	151%	170%	155%

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 2015 ” in this “VII. 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 relative total return experienced by our stockholders;



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT


•	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. With respect to the long-term incentives for recent prior years, including 2015 , the Committee, with the assistance of our Compensation Consultant, assessed the economic climate, executive compensation market data and our business needs and determined that a mix of performance-contingent equity and time vesting equity would be appropriate to achieve our executive long-term incentive program objectives. In order to accomplish its overall objectives, the Committee identified the following factors for developing the framework of the long-term incentive program. The program should:


•	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 Incentive awards;


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


•	align executives with stockholders to maximize total stockholder return;


•	be efficient from a tax and stockholder dilution perspective;


•	serve as a retention vehicle;


•	be cash-efficient by emphasizing the use of Common Stock; 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.

RSUs

General . There are three general categories of RSUs which the Committee has granted to executives in recent years, ⁵ which generally have the vesting attributes noted below: ⁶

•

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 ⁷ 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. The Committee reviews and approves the executive RSU program summary, which summarizes the parameters of the Annual RSUs, New Hire RSUs and Promotion RSUs for grant to executives in the current fiscal year pursuant to our 2013 Plan. No New Hire RSUs or Promotion RSUs were granted to any NEO in 2015.

In addition to the foregoing, 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 2015.

⁵ Commencing in 2014, we transitioned from the use of restricted stock awards ("RSAs") to RSUs for long-term incentives. As such, references to RSUs in this "—CD&A—Elements of Executive Compensation and Benefits—Long-Term Incentives—RSUs—General" generally apply equally with respect to RSAs for recent years prior to 2014.

⁶ With respect to RSAs granted prior to 2014, cash dividends on shares of restricted stock underlying such RSAs are paid at the same times and in the same amounts as on other shares of our Common Stock. With respect to RSUs granted since 2014, 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.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

2015 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 2015 , the Committee authorized, as 2015 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 2016 , 2017 and 2018 (“ 2015 Time RSUs”) and (2) Performance RSUs which may vest based on our TSR Rank (defined below) relative to a TSR Peer Group (defined below) over a three year performance period as further described below (“ 2015 Performance RSUs”). With respect to the 2015 Annual RSUs granted to the NEOs, the grant value mix between 2015 Time RSUs and 2015 Performance RSUs is approximately 35% and 65% ⁸ , respectively, of the combined total grant value for each NEO (“Grant Value”). In connection with the 2015 Annual RSUs, the Committee authorized the grant of approximately 461,557 2015 Time RSUs to 991 employees and approximately 506,515 ⁹ 2015 Performance RSUs to 58 employees, including 56,712 2015 Time RSUs to the NEOs and 195,972 ¹⁰ 2015 Performance RSUs to the NEOs.

Each 2015 Performance RSU is issued pursuant to the 2013 Plan and represents a contingent right to receive one share of Common Stock. The terms of the 2015 Performance RSUs generally provide that, subject to the executive remaining an employee or director of ours (including our affiliates) until February 19, 2018 , 0% to 100% of such RSUs may vest (i.e., forfeiture restrictions terminate) on February 19, 2018 based upon the Company’s total stockholder return (“TSR”) performance ranking (“TSR Rank”) relative to a peer group of companies approved by the Committee (“TSR Peer Group”) for the three year period ending February 12, 2018 (“TSR Period”). ¹⁰ If the TSR Rank is at the 30 ^th percentile or more up to the 55 ^th percentile, then 33.34% to 66.67% of the Performance RSUs vest on a pro rata basis based upon the level of the TSR Rank (i.e., approximately an additional 1.3336% of the units vest for each 1.0 percentile increase in the TSR Rank above the 30 ^th percentile up to the 55 ^th percentile), with 66.67% of the Performance RSUs vesting at the 55 ^th percentile. If the TSR Rank is at the 55 ^th percentile or more, then 66.67% to 100% of the Performance RSUs vest on a pro rata basis based upon the level of the TSR Rank (i.e., approximately an additional 0.95229% of the units vest for each 1.0 percentile increase in the TSR Rank above the 55 ^th percentile up to the 90 ^th percentile (or above)), with 100% of the units vesting at or above the 90 ^th percentile. However, if the TSR is negative for the TSR Period and the TSR Rank is at or above the 30 ^th percentile, only 33.34% of the Performance RSUs will vest. If the TSR Rank is below the 30 ^th percentile, 100% of the Performance RSUs will be forfeited.

⁸ With respect to the 2015 Performance RSUs, the 65% of Grant Value represents the target level of such award for each NEO (“Target Level”). 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 Accounting Standards Codification Topic 718 ("ASC 718") may be more or less than 65% of the Grant Value.

⁹ The number of 2015 Performance RSUs granted is the maximum number of such RSUs that will vest at or above a 90 ^th percentile TSR Rank being achieved upon completion of the TSR Period.

¹⁰ The Committee has the authority to interpret and determine the application and calculation of matters relating to the determination of TSR and TSR Rank and to make adjustments it deems appropriate to reflect changes in (1) 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, or (2) the TSR Peer Group, including as a result of any TSR Peer Group company becoming bankrupt, being acquired, disposing of a material portion of its assets (including spin-offs), being delisted from a stock exchange, or splitting its common stock (or other change to such company’s stock or capitalization).



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

The graph below illustrates the payout range for the 2015 Performance RSUs.

The TSR Peer Group utilized in connection with the 2015 Performance RSUs differs from, but overlaps with, the Peer Group utilized in connection with the Competitive Market Analysis for assessing the executives’ 2015 compensation. The TSR Peer Group ¹¹ includes companies which the Committee believes are comparable investment alternatives to us, as listed below:



• American Tower Corporation	• Prologis, Inc.
• AT&T Inc.	• SBA Communications Corporation
• Boston Properties, Inc.	• Simon Property Group, Inc.
• Equinix, Inc.	• Sprint Corporation
• F5 Networks, Inc.	• T-Mobile US, Inc.
• Frontier Communications Corporation	• United States Cellular Corporation
• General Growth Properties, Inc.	• Ventas, Inc.
• HCP, Inc.	• Verizon Communications Inc.
• Juniper Networks, Inc.	• Vornado Realty Trust
• Lamar Advertising Company	• Welltower, Inc. (formerly Health Care REIT, Inc.)
• NetApp, Inc.	• Windstream Holdings, Inc.

The levels at which the TSR Rank vesting targets are established for a given year’s Performance RSU grant 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 2015 ” in this “VII. 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

¹¹ Similar to the changes approved for the 2016 Peer Group (see footnote 2 above in this CD&A), the Committee approved the removal of Windstream Holdings, Inc. for the 2016 TSR Peer Group to be utilized in connection with Performance RSUs granted to executives in February 2016.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

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 RSU multiples of base salary for each executive. An RSU multiple of base salary, generally based on our overall financial performance for the prior year and each executive’s individual performance and anticipated future role, is 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 2015 Time RSUs is summarized in notes 2 and 13 to our consolidated financial statements in our 2015 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 30 trading days ending on the date of grant, to value the 2015 Performance RSUs for purposes of determining the number of units to be granted.

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 shares 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, which may include Towers Watson and others, 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 3.7% as of December 31, 2015, and our 2015 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 the third party surveys identified above) as well as our Peer Group.

Treatment of RSUs Upon Eligible Retirement . In November 2015, the Board 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 nine 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.

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 NEO and certain other senior officers (as amended, “Severance Agreements”). We do not currently have employment agreements with any of our executives other than the Severance Agreements.

Pursuant to each Severance Agreement, we are 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).

In 2014, the Committee 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



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

1986, as amended (“Code”)) (“Excise Tax Payment”). In connection with the adoption of such policy, the existing Severance Agreements were amended to remove all 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, which may include Towers Watson and others. Subsequent Severance Agreements may be different as a result of such reviews.

Details regarding the severance benefits provided under the Severance Agreements, including a description of certain amendments approved by the Committee at the First Regular Committee Meeting of 2016, and the potential value thereof are provided below at “—Potential Payments Upon Termination of Employment” in this “VII. Executive Compensation.”

Other Benefits and Perquisites

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

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) beginning in 2014, 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 limitations. The value of our Base Match and Discretionary Match contributions for each NEO for the 2015 , 2014 and 2013 401(k) Plan years and the Discretionary Contributions for each NEO for the 2015 and 2014 401(k) Plan years are provided below in the table at “—Summary Compensation Table” in this “VII. 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, dental, vision, life and disability insurance. The value of the health and welfare benefits paid by us for each NEO in 2015 , 2014 and 2013 is provided below in the tables at “—Summary Compensation Table” and “—All Other Compensation Table” in this “VII. Executive Compensation.”

Relocation Benefits

In general, we do not offer our executives significant perquisites, other than relocation assistance (which includes expatriate benefits for international assignments). We generally offer relocation assistance to all of our employees 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 new hire 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 2015 .

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 Common 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



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

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:



Executive	Title	Multiple of Base Salary ^(a)
W. Benjamin Moreland	President & CEO	6X
Jay A. Brown	SVP, CFO & Treasurer	3X
James D. Young	SVP & COO	3X
E. Blake Hawk	Former EVP & General Counsel	3X
Patrick Slowey	SVP & CCO	3X


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

The NEOs generally have until March 25, 2018 to meet the applicable stock ownership level. ¹² As of the Record Date, each of the NEOs serving at that time held shares of Common Stock having a value in excess of such NEO’s applicable share 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, 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. 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.

Accounting and Tax Impacts upon Executive Compensation

For a discussion of the accounting impacts on various elements of long-term incentive compensation, see notes 2 and 13 to our consolidated financial statements in our 2015 Form 10-K.

Section 162(m) of the Code generally disallows a public company’s tax deduction for compensation paid to the CEO and the four other most highly compensated officers in excess of $1 million in any taxable year, other than the principal financial officer. However, qualifying performance-based compensation is not subject to the deduction limit if certain requirements are satisfied.

¹² 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.



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

In determining executive compensation, the Committee considers, among other factors, the possible tax consequences. Tax consequences, including tax deductibility, are subject to many factors (such as changes in the tax laws) 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, does not limit compensation to those levels or types of compensation that will be deductible by us.

To this end, the AIP does not qualify for the Section 162(m) exemption even though it is an annual performance-based cash program based on pre-established goals and objectives primarily because the Committee maintains some level of subjectivity regarding the payout multiple applied to the executive based on the Committee’s assessment of the executive’s individual performance.

All compensation attributable to the vesting of Performance RSAs during 2015 satisfied the requirements for deductibility under Section 162(m). For 2015 , the portion of combined base salary, Annual Incentive, and vesting of Time RSAs in excess of $1 million for Messrs. Moreland, Young, Hawk and Slowey does not qualify as performance-based compensation under Section 162(m) and is therefore not deductible by us.

CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

Potential Payments Upon Termination of Employment


•	Severance Agreements. We have entered into Severance Agreements containing non-compete and non-solicitation provisions with each NEO (See "—Subsequent Amendments to Severance Agreements" below for a summary of certain amendments to the Severance Agreements approved by the Committee in February 2016).

Pursuant to each Severance Agreement, we are required to provide severance benefits to the officer if such officer’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 officer’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, 2015 not during a change in control period, the executive officer would have been entitled to:

•

a lump sum payment equal to the sum of the officer’s base salary and Annual Bonus multiplied by two (for Messrs. Moreland and Hawk) or one (for all other NEOs covered by a Severance Agreement). For Messrs. Moreland and Hawk, Annual Bonus is defined for purposes of the Severance Agreement as 75% of such officer’s base salary. For Messrs. Young and Slowey, Annual Bonus is defined for purposes of the Severance Agreement as 55% of such officer’s base salary. For Mr. Brown, Annual Bonus is defined for purposes of the Severance Agreement as 65% of base salary;


•	a prorated cash amount equal to the officer’s Annual Bonus for the year of termination 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 either two years (for Messrs. Moreland and Hawk) or one year (for all other NEOs covered by a Severance Agreement);


•	continued participation in the 401(k) Plan for the calendar year of the date of termination 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

•

for Messrs. Moreland and Hawk, immediate vesting of all Restricted Stock Awards (as defined in the Severance Agreements), RSUs and stock options, other than Performance Awards (as defined in the Severance Agreements), which have the opportunity to continue to vest as if the officer remained an employee after the date of termination; and for all other NEOs covered by a Severance Agreement, immediate vesting of all stock options and continued vesting of all Restricted Stock Awards (including RSUs) for two years after termination.

In connection with a Qualifying Termination Upon Change in Control, the officer is entitled to:


•	a lump sum payment equal to the sum of the officer’s base salary and Annual Bonus multiplied by three (for Messrs. Moreland and Hawk) or two (for all other NEOs covered by a Severance Agreement);


•	a prorated cash amount equal to the officer’s Annual Bonus for the year of termination 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 either three years (for Messrs. Moreland and Hawk) or two years (for all other NEOs covered by a Severance Agreement);


•	continued participation in the 401(k) Plan for the calendar year of the date of termination 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



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

•

immediate vesting of any outstanding Restricted Stock Awards (as defined in the Severance Agreements), RSUs and stock options held by the officer, provided that such immediate vesting only applies to Performance Awards 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. The following table and footnotes thereto summarize the alternative termination benefits that would be payable under different termination scenarios in accordance with each NEO’s Severance Agreement. The information provided assumes the NEO’s termination occurred as of December 31, 2015 .

(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 payment equal to the sum of the NEO’s base salary and Annual Bonus multiplied by three and two for Messrs. Moreland and Hawk, and two and one for Messrs. Brown, Young and Slowey for a Qualifying Termination Upon Change in Control and Qualifying Termination, respectively. In connection with Mr. Hawk's Retirement, Mr. Hawk would not be entitled to these benefits with respect to a termination occurring after December 31, 2015.

(c)

Represents the value of outstanding and unvested RSAs and RSUs as of December 31, 2015 (calculated as the number of accelerated RSAs and RSUs multiplied by $86.45 , the closing price per share of our Common Stock on December 31, 2015 ) 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). In connection with 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 continues 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 (as defined in the Severance Agreements), RSUs and stock options either (1) immediately vest for Messrs. Moreland and Hawk, provided that any Performance Awards continue to vest pursuant to the



CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

applicable performance criteria or (2) continue to vest for two years after termination for Messrs. Brown, Young and Slowey, subject to the achievement of the relevant performance criteria for Performance RSAs and Performance RSUs.


(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, 2015 , and any prior year actual annual incentives relating to 2014 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 2015, the year in which termination of employment is assumed to occur under this scenario. Assuming termination of employment occurs on December 31, 2015 , this amount includes our Discretionary Match and Discretionary Contribution for 2015 , which is $7,950 for the Discretionary Match since each of the NEOs achieved the level of contribution necessary for 2015 to be eligible for the full 3% Discretionary Match and $10,600 for each NEO for the Discretionary Contribution, which is the maximum amount allowable under the Code for such contribution.

In connection with Mr. Hawk's Retirement, Mr. Hawk would not be entitled to these benefits with respect to a termination occurring after December 31, 2015.


(e)	Represents an estimate of the alternative total potential payments upon termination of employment that would be paid to or accrued for each NEO assuming the NEO’s employment terminated under different scenarios as of December 31, 2015 .

Subsequent Amendments to Severance Agreements

In February 2016, in connection with the CEO Succession Plan, the Committee approved amended and restated Severance Agreements for Messrs. Moreland and Brown to reflect their new positions of Executive Vice Chairman and President and CEO, respectively, effective as of June 1, 2016, as well as to effect certain other amendments. In addition, the Committee approved amendments to the Severance Agreements of the other NEOs.

The amended and restated Severance Agreement for Mr. Moreland restates his severance agreement and makes amendments primarily to (1) reflect that Mr. Moreland’s position will be EVC effective June 1, 2016, (2) amend the defined term “Annual Bonus” to mean Mr. Moreland’s target annual incentive for the calendar year of termination, (3) remove our obligation to pay Mr. Moreland a multiple of base salary and Annual Bonus in the event of a Qualifying Termination not occurring during a Change in Control Period, (4) remove accelerated vesting of Mr. Moreland’s outstanding Stock Options and Restricted Stock Awards (including RSUs) (collectively, “Equity Awards”), in the event of a Qualifying Termination not occurring during a Change in Control Period and replace such accelerated vesting with continued vesting of such Equity Awards pursuant to their terms as if he were an employee, and (5) provide that in the event of a Post-2017 Termination, Mr. Moreland would receive the benefits normally provided for a Qualifying Termination not occurring during a Change in Control Period (including continued vesting of Equity Awards as if he were an employee), except for our release of any claims against Mr. Moreland, and provided that, in the event such Post-2017 Termination were for Cause, certain of the other Qualifying Termination benefits would be forfeited. "Post-2017 Termination” means any termination of Mr. Moreland’s employment with us and our subsidiaries on or after December 31, 2017 for any reason other than (1) pursuant to a Qualifying Termination or (2) due to Disability or death.

The amended and restated Severance Agreement for Mr. Brown restates his severance agreement and makes amendments primarily to (1) reflect that Mr. Brown’s position will be President and CEO effective June 1, 2016, and (2) amend the defined term “Annual Bonus” to mean Mr. Brown’s target annual incentive for the calendar year of termination.

The Severance Agreement amendments for the other NEOs amend the defined term “Annual Bonus” in the applicable severance agreement to mean the executive’s target annual incentive for the calendar year of termination, with no other changes.

VIII. 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 Investor Relations section of our website at http://www.crowncastle.com/investor/corpgovernance.asp .

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 2015 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.

IX. OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 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. Executive officers, directors and greater than 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

Based on the review of copies of such reports furnished to us and written representations that no other reports were required, we believe that, during the 2015 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 each of Messrs. Brown, Fisher, Hawk, Kelley, Moreland, Slowey and Young filed one late report with respect to two transactions.

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. The request must also include the potential candidate’s written consent to being named in the proxy statement as a nominee and to serving as a director if nominated and elected. The stockholder or group of stockholders making the recommendation must also disclose, with the written request, the number of securities that the stockholder or group beneficially owns and the period of time the stockholder or group has beneficially owned the securities. Additional information may be requested from the nominee or the stockholder by the NCG Committee from time to time. As and if determined by the NCG Committee, potential candidates must also make themselves available to be interviewed by the NCG Committee, the Board and members of our executive management.

The NCG Committee reserves the right not to have any communications with the recommending stockholder or the candidate regarding the evaluation process of the candidate or the NCG Committee’s conclusions regarding such evaluation.

Stockholder Nominations and Proposals for 2017 Annual Meeting

Stockholders wishing to have a proposal included in the Board’s 2017 proxy statement must submit the proposal so that our Corporate Secretary receives it at our principal executive offices no later than December 5, 2016 . If the date of the 2017 Annual Meeting is changed by more than 30 days from the date of the 2016 Annual Meeting, the deadline for submitting proposals to be included in the Board’s 2017 proxy statement will be a reasonable time before we begin to print and mail our proxy materials for our 2016 Annual Meeting.

Stockholders may make nominations for directors and introduce proposals or other business to be considered at the 2017 Annual Meeting provided such nominations and proposals are in accordance with our By-Laws and involve proper matters for stockholder action. Such stockholder nominations and proposals and other business for the 2017 Annual Meeting must be received not less than 90 days (February 18, 2017 ) nor more than 120 days (January 19, 2017 ) before May 19, 2017 (the first anniversary date of the 2016 Annual Meeting) at our offices located at Crown Castle International Corp., 1220 Augusta Drive, Suite 600, Houston, TX 77057, Attn: Corporate Secretary. If the 2017 Annual Meeting is advanced by more than 30 days, or delayed by more than 90 days, from the date of the 2016 Annual Meeting, the nomination or proposal must be delivered not earlier than the 120th day prior to the 2017 Annual Meeting and not later than the later of the 90th day prior to the 2017 Annual Meeting or the 10th day following the announcement of the change in the 2017 Annual Meeting date. The notice of nominations for the election of directors must set forth certain information concerning the stockholder giving the notice and each nominee. A copy of the applicable By-Laws provision may be obtained, without charge, upon written request to our Corporate Secretary.

If the date of the 2017 Annual Meeting is advanced or delayed by more than 30 calendar days from the date of the 2016 Annual Meeting, we shall, in a timely manner, inform stockholders of such change, by including a notice, under Item 5, in our earliest possible quarterly report on Form 10-Q. The notice will include the new deadline for submitting proposals to be included in the Board’s 2017 proxy statement and the new date for determining whether we have received timely notice of a nomination or proposal.

CROWN CASTLE INTERNATIONAL CORP.		PROXY STATEMENT

Appendix A

Independence Categorical Standards

(October 16, 2008)

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”. Each of the relationships described below is not a “material relationship” by itself and therefore will not prevent a Director from being “independent”:

•

Certain Relationships . Directorship more than three years after: (i) the Director was employed by the Company; (ii) an immediate family member of the Director (“Family Member”) was employed by the Company as an executive officer; (iii) 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 (iv) 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 (i) is employed by the Company in a non-officer position or (ii) is employed by, but is not a partner with, the Auditor and does not personally work on the Company’s audit.


•	Compensation . A Director or a Family Member receives or 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 . A 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, does not exceed the greater of (a) $1 million, or (b) two percent (2%) of such other company’s consolidated gross revenues.


•	Indebtedness . A 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 . A Director 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 the organization does not exceed the greater of (a) $500,000, or (b) one percent (1%) of that organization’s total annual receipts.


•	Stock Ownership . Direct or indirect ownership by a Director of a significant amount of Company stock (including securities convertible into Company stock).

An “immediate 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 is not described above, or is outside of the parameters above, and the Board determines that the Director is “independent”, the Board will disclose the basis for such determination in the Company’s annual proxy statement. In addition, members of the Audit Committee are subject to additional standards relating to their independence.
