VOTING INSTRUCTION AND INFORMATION

This Proxy Statement is furnished in connection with the solicitation of proxies by the board of directors of Macquarie Infrastructure Company LLC, a Delaware limited liability company, for the Annual Meeting of Shareholders of Macquarie Infrastructure Company LLC to be held on Thursday, May 31, 2012 at 10:00 A.M. (Eastern Time).

Be sure to have your 12-Digit Control Number to enter the Annual Meeting. The notice of Annual Meeting, proxy statement and proxy are first being distributed to shareholders on or about April 20, 2012.

Purpose of Meeting

As described in more detail in this proxy statement, shareholders will vote on the following proposals at the Annual Meeting:

• the election of directors eligible for election by our shareholders to our board of directors to serve for a one-year term that expires at our 2013 Annual Meeting (Proposal 1);

• the ratification of the selection of KPMG LLP as our independent auditor for the fiscal year ending December 31, 2012 (Proposal 2);

• the approval, on an advisory basis, of executive compensation (Proposal 3); and

• any other business as may be properly brought before the meeting.

Internet and Electronic Availability of Proxy Materials

As permitted by the Securities and Exchange Commission, or the SEC, we are sending a Notice of Internet Availability of Proxy Materials, or the Notice, to shareholders who hold LLC interests in “street name” through a bank, broker or other holder of record. The Notice also provides instructions on how to access your proxy card to be able to vote through the Internet or by telephone. All such shareholders will have the ability to access this proxy statement and our 2011 annual report on a website referred to in the Notice or to request a printed set of these materials at no charge. Instructions on how to access these materials over the Internet or to request a printed copy may be found in the Notice.

We are either mailing or providing notice and electronic delivery of the proxy solicitation materials and our 2011 annual report at https://materials.proxyvote.com/55608B on or around April 20, 2012 to all shareholders entitled to vote at the Annual Meeting.

If you hold your LLC interests through a bank, broker or another financial institution, refer to the information provided by that entity for instructions on how to elect this option. Choosing to receive future proxy materials by email will save us the cost of printing and mailing documents and will reduce the impact of annual meetings on the environment. An election to receive proxy materials by mail or email will remain in effect until terminated.

If you need an additional proxy card and are a record holder, contact Michael Kernan, our General Counsel, at 212-231-1849; if you are a beneficial owner, contact your bank, broker or other financial institution through which you hold your LLC interests.

Approval of Proposals and Solicitation

Each shareholder who owned LLC interests on April 2, 2012, the record date for the determination of shareholders entitled to vote at the Annual Meeting, is entitled to one vote for each LLC interest. On April 2, 2012, we had 46,474,212 LLC interests issued and outstanding that we believe were held by 60 holders of record representing approximately 18,300 beneficial holders.

Quorum

Under the third amended and restated operating agreement of the Company, which we refer to as the LLC agreement, the shareholders participating in person or by proxy holding a majority of the outstanding LLC interests entitled to vote shall constitute a quorum at a meeting of shareholders of the Company. Holders of LLC interests as of the record date are the only shareholders entitled to vote at the Annual Meeting. LLC interests represented by proxies that are marked “abstain” or that are represented by broker non-votes will be counted as present for purposes of determining the presence of a quorum. A broker non-vote occurs when the broker holding LLC interests for a beneficial owner does not vote on a particular proposal because the broker does not have discretionary voting power to vote on that proposal without specific voting instructions from the beneficial owner. Proposal 2 described in this proxy is a “discretionary” item. Proposals 1and 3 described in this proxy statement are “non-discretionary” items.

If the persons participating or represented by proxies at the Annual Meeting do not constitute a majority of the holders of outstanding LLC interests entitled to vote as of the record date, we will adjourn or postpone the Annual Meeting to a later date.

Approval of Proposals

Election of Directors.  For the election of directors (Proposal 1), the affirmative vote of a plurality of the votes cast on such proposal is required. The LLC agreement provides that shareholders are entitled, at the Annual Meeting of shareholders of the Company, to vote for the election of all of the directors other than the director, and alternate therefor appointed by our Manager. You may vote FOR or AGAINST any or all director nominees or you may ABSTAIN as to one or more director nominees. An abstention will not be counted as a vote cast. A broker non-vote will also not be counted as a vote cast.

Ratification of the Appointment of the Independent Auditor.  For the ratification of the independent auditor (Proposal 2), the affirmative vote of at least a majority of shares represented at the meeting in person or by proxy is required. You may vote FOR or AGAINST or you may ABSTAIN from the ratification of the independent auditor. An abstention will have the effect of a negative vote on this matter.

3

Approval, on an Advisory Basis, of Executive Compensation.  For the approval, on an advisory basis, of executive compensation (Proposal 3), the affirmative vote of at least a majority shares represented at the meeting in person or by proxy is required. You may vote FOR or AGAINST or you may ABSTAIN from the advisory vote on executive compensation. An abstention will have the effect of a negative vote on this matter. A broker non-vote will not be counted as present for purposes of calculating the voting results on this matter.

Other Matters.  Any other proposal that properly comes before the Annual Meeting must be approved by the affirmative vote of at least a majority of the votes represented at the meeting in person or by proxy in order to pass.

All votes will be tabulated by Broadridge Financial Services, the proxy tabulator and inspector of election appointed for the Annual Meeting. Broadridge Financial Services will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

Ensuring Your Vote Counts

Under rules of the New York Stock Exchange, or NYSE, if you are a beneficial owner and hold your LLC interests in “street name,” you must give your bank, broker or other holder of record specific voting instructions for your LLC interests by the deadline provided in order to ensure your LLC interests are voted in the way you would like.

If you do not provide voting instructions to your bank, broker or other holder of record, whether your LLC interests can be voted by such person depends on the type of item being considered for vote.

Non-Discretionary Items.  Proposal 1, the election of directors, and Proposal 3, the approval, on an advisory basis, of executive compensation, are “non-discretionary items” and may not be voted on by brokers, banks or other holders of record who have not received specific voting instructions from beneficial owners. If you do not provide specific voting instructions, your LLC interests will be recorded as a broker non-vote and will not be counted as a vote cast or as present for purposes of calculating voting results.

Discretionary Items.  Proposal 2, the ratification of the appointment of the independent auditor, is a “discretionary item” and brokers, banks or other holders of record can vote your LLC interests on the ratification of the independent auditor in their discretion unless they receive specific voting instructions from you.

Solicitation of Proxies

We will bear the cost of the solicitation of proxies, including the preparation, printing and mailing of this proxy statement and the proxy card. In addition to the solicitation of proxies by mail, solicitation may be made by certain employees of The Macquarie Group by telephone, telecopier or other means. These employees will receive no additional compensation for such solicitation. The Company will reimburse brokers and other nominees for costs incurred by them in mailing proxy materials to beneficial holders in accordance with the rules of the NYSE.

Delivery of Documents to Shareholders Sharing an Address

If you are the beneficial owner, but not the record holder, of LLC interests, the broker, bank or other financial institution through which you hold your LLC interests may only deliver one copy of this proxy statement and our 2011 annual report to multiple shareholders who share an address unless that nominee has received contrary instructions from one or more of the shareholders. We will deliver promptly, upon written or oral request, to a shareholder at a shared address to which a single copy of the documents was delivered a copy of this proxy statement and our 2011 annual report. A shareholder who wishes to receive a separate copy of the proxy statement and annual report, now or in the future, should submit this request by writing to Macquarie Infrastructure Company LLC, Attn: Investor Relations 125 West 55th Street, New York, NY 10019, or by calling 212-231-1825. If you are a beneficial owner and would like to receive a separate copy of this proxy statement and our 2011 annual report, please contact the broker, bank or other financial institution through which you hold your LLC interests. Beneficial owners sharing an address who are receiving multiple copies of proxy materials and annual reports and who wish to receive a single copy of such materials in the future will also need to contact their broker, bank or other financial institution to request that only a single copy of each document be mailed to all shareholders at the shared address in the future.

PROPOSAL 1:
ELECTION OF DIRECTORS

Election of Directors

Four directors are eligible to be elected by our shareholders at this Annual Meeting and will serve a term that expires at our 2013 Annual Meeting. Each of Messrs. Brown, Carmany, Lentz and Webb has been nominated for re-election.

The following biographies highlight the qualifications and experience of the directors nominated for election, and support the nomination and governance committee’s determination that these individuals are particularly qualified to serve on our board. The four nominees for election at the Annual Meeting are as follows.

Norman H. Brown, Jr. has served as a director of the Company since December 2004. He currently serves as a Member and Senior Managing Director of Brock Capital Group LLC, which provides investment banking services for early stage and middle market companies, a position he has held since December 2003. Mr. Brown’s previous experience comprises over 30 years of experience in the investment banking business. During 2002 and 2003, Mr. Brown attended to private investments. From December 2000 to December 2001, he was Managing Director and Senior Advisor for Credit Suisse First Boston in the Global Industrial & Services Group with new business development responsibility for Latin America. During Mr. Brown’s 15 years at Donaldson, Lufkin & Jenrette Securities Corporation, from June 1985 to December 2000, he was a member of the Mergers & Acquisitions Group, established and headed the Restructuring Group, and headed the Global Metals & Mining Group. Until December 2009, Mr. Brown was the lead independent director for W.P. Stewart & Co. Growth Fund, Inc.

Mr. Brown brings in-depth knowledge of financial markets and broad leadership experience to our board of directors, through his long tenure in the financial industry. His prior work and expertise in mergers and acquisitions and debt restructurings has allowed him to provide valuable advice on our past acquisitions and our recent efforts to strengthen our balance sheet. Mr. Brown’s experience as an independent director and lead director for other companies provides him with unique insight on corporate governance matters, which he has shared with the Company.

George W. Carmany, III has served as a director of the Company since December 2004. Since 1995, he has served as President of G.W. Carmany and Co., Inc., which advises developing companies in the life sciences and financial services industries. Mr. Carmany is a Senior Advisor to EnGeneIC Pty Ltd., Brown Brothers Harriman & Co, and Essex Woodlands. In 2010, he retired as a Director of SunLife Financial, Inc. He is a member of the educational advisory board of the Harvard Medical School. From 1999 to 2001, he served as Chairman and Chief Executive of Helicon Therapeutics and continued to serve as Chairman of Helicon Therapeutics through August 2005. From 1996 to 1997, he also served as Chairman of the New England Medical Center Hospitals. Mr. Carmany’s previous experience includes over 20 years at the American Express Company, where he held senior positions in its international banking, corporate and asset management divisions and nine years at Bankers Trust Company.

Mr. Carmany is an experienced executive, and he adds an important dimension to our board’s expertise through his considerable financial literacy and his work in advising developing companies. Mr. Carmany’s experience and background allows him to provide oversight and advice on financial reporting and accounting matters. As an advisor to developing companies, Mr. Carmany encounters and advises on a range of business, legal, risk management and financial issues. This experience has been valuable as our board has worked with our management team to address issues and manage risks arising out of the financial crisis and the slow economic recovery.

H.E. (Jack) Lentz has served as a director of the Company since August 2011. He currently serves as the non-executive chairman of the board of Rowan Companies Inc., a position he has held since January 2009. He also serves on the boards of Carbo Ceramics Inc. (since 2003), Peabody Energy Corporation (since 1998) and WPX Energy, Inc. (since 2012). He is a member of the audit committee and chair of the compensation committee of Carbo Ceramics Inc. and a member of the compensation committee of Rowan Companies, Inc. From March 2009 until May 2011, Mr. Lentz was a Managing Director at Lazard Freres & Co. Between September 2008 and March 2009, he was a Managing Director at Barclay’s Capital. From 1993 until

5

September 2008, he was Managing Director at Lehman Brothers, where he headed the natural resources group (1993 – 1997) and was active in merchant banking. From 1988 to 1993, he was the Vice Chairman of Wasserstein Perella & Co. and head of its energy group. He started his career at Lehman Brothers in 1971.

Mr. Lentz is an experienced executive and board member with broad experience in the natural resources and energy industries, both of which are traditional infrastructure sectors. That experience allows him to inform our board on a wide range of governance, financial and operational issues, especially as they relate to the operations of our energy businesses, and the development of the Company’s strategic direction.

William H. Webb has served as a director of the Company since December 2004. He served as a member of the board of directors of Pernod Ricard S.A. from May 2003 until November 2009. Mr. Webb’s previous experience includes over 35 years in managing businesses of the Philip Morris group (now comprising Altria Group, Inc., Philip Morris International Inc. and Kraft Foods Inc. following the spin-off of Kraft Foods and Philip Morris International from the Altria Group) around the world. Mr. Webb was Chief Operating Officer for Philip Morris Companies Inc. in New York between May 1997 and August 2002. He also served as Vice Chairman of the board of directors of Philip Morris from August 2001 to August 2002. Mr. Webb has been a consultant to the Altria Group following his retirement from Philip Morris in August 2002, until October 2005.

Mr. Webb’s experience in senior management and on the board of large public companies allows him to participate meaningfully in overseeing our Manager’s activities and in providing useful advice to our management team. His role as a director of other public companies allows him to inform our board as to corporate governance issues and trends and to act as an effective lead independent director for the Company. Mr. Webb uses his management experience to help our board and management fashion our business strategy, identify risks and oversee risk management and address key challenges, such as those the Company faced due to the slow economic recovery and the continuing focus on cost management.

Recommendation of the Board

Our board recommends that you vote FOR the election of each of Messrs. Brown, Carmany, Lentz and Webb to our board as directors for a term ending at our 2013 Annual Meeting. An affirmative vote of a plurality of the votes cast is required to elect each of Messrs. Brown, Carmany, Lentz and Webb.

PROPOSAL 2:
RATIFICATION OF SELECTION OF INDEPENDENT AUDITOR

General

Our board has recommended and asks that you ratify the selection of KPMG LLP as our independent auditor for the Company for the fiscal year ending December 31, 2012. You would be so acting based on the recommendation of our audit committee.

KPMG LLP was engaged by us following our initial public offering in December 2004 to audit our annual financial statements for the 2004 fiscal year and was appointed by our audit committee and ratified by shareholders to audit our annual financial statements for each subsequent fiscal year. Based on its past performance during these audits, the audit committee of the board has selected KPMG LLP as our independent auditor to perform the audit of our financial statements and our internal control over financial reporting for 2012. KPMG LLP is a registered public accounting firm.

The affirmative vote of a majority of the shares represented at the meeting in person or by proxy is required to ratify the appointment of KPMG LLP. If you do not ratify the selection of KPMG LLP, our board will reconsider its selection of KPMG LLP and may, but is not required to, make a new proposal for an independent auditor.

Representatives of KPMG LLP are expected to be present at the Annual Meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to questions.

Fees

The chart below sets forth the total amount paid or payable by us to KPMG LLP in connection with the audit of our consolidated financial statements for the years indicated below and the total amounts billed to us by KPMG LLP for other services performed in those years, breaking down these amounts by category of service:

	2011		2010
Audit Fees(1)	$	2,344,000	$	2,319,000
Audit-Related Fees(2)		185,500		171,730
Total	$	2,529,500	$	2,490,730

(1) “Audit Fees” are fees paid to KPMG LLP for professional services for the audit of our consolidated financial statements included in our annual reports on Form 10-K and the audit of our internal control over financial reporting, as well as the review of financial statements included in our quarterly reports on Form 10-Q. The amount for 2011 and 2010 includes fees related to the audit and review of District Energy, of which we own a 50.01% controlling interest. Audit fees incurred by District Energy will continue to be included in our consolidated results.

(2) “Audit-Related Fees” are fees billed by KPMG LLP for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements, including in connection with attestation reports on fees paid to our Manager and in connection with our operating businesses and the audit of our 401(k) Plan. The amounts do not include fees related to the audit of IMTT, our 50% equity investment. Audit-related fees for IMTT were $355,000 for both 2011 and 2010.

Pre-Approval Policies and Procedures

The audit committee has established policies and procedures for its appraisal and approval of audit and non-audit services. The audit committee has the sole authority to pre-approve any audit and non-audit services to be provided by any registered public accounting firm. The audit committee has delegated to the chairman of the committee the authority to approve additional audit and non-audit services of KMPG LLP and any additional accounting firms. The delegation is limited to an aggregate of $50,000 in fees at any one time outstanding and not ratified by the audit committee, and confirmation of compliance with independence standards. The audit committee or its chairman has pre-approved all of the services provided by KPMG LLP since its engagement. All other audit-related, tax and other engagements may be approved by the audit committee prospectively.

In making its recommendation to ratify the selection of KPMG LLP as our independent auditor for the fiscal year ending December 31, 2012, the audit committee has considered whether the services provided by KPMG LLP are compatible with maintaining the independence of KPMG LLP and has determined that such services do not interfere with KPMG LLP’s independence.

Recommendation of the Board

Our board recommends that, based on the recommendation of the audit committee, you vote FOR the ratification of the selection of KPMG LLP to serve as the independent auditor for the Company for the fiscal year ending December 31, 2012.

PROPOSAL 3:
APPROVAL, ON AN ADVISORY BASIS, OF EXECUTIVE COMPENSATION

General

Our board has recommended and asks that you approve, on an advisory basis, the compensation of our named executive officers, as disclosed pursuant to Item 402 of Regulation S-K on pages 21 – 34 of this proxy statement, which includes the “Compensation Discussion and Analysis” section and the compensation tables and related narrative disclosure.

The recently enacted Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our shareholders to vote to approve, on an advisory (nonbinding) basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with Item 402 of Regulation S-K, which is the Securities and Exchange Commission’s rule setting forth executive compensation disclosure requirements.

As described in detail under the headings “Compensation Discussion and Analysis — General” and “Compensation Discussion and Analysis — Objectives of Macquarie’s Compensation Program,” the Company has a management services agreement with our Manager, a member of the Macquarie Group. Our Manager is responsible for the conduct of our Company’s day-to-day business and affairs and is entitled to receive base and potentially performance fees for the provision of its services. The Macquarie employees who serve as our named executive officers have been seconded to us by our Manager on a full-time basis and we do not pay any compensation to them. Under our management services agreement, the services performed for the Company by our Manager are provided at our Manager’s expense, including all of the compensation of our named executive officers. The elements of the compensation program for our named executive officers derive from the general program established for employees of Macquarie. Macquarie’s approach is designed to drive shareholder returns over the short and long term, both for Macquarie shareholders as well as for shareholders of the entities managed by Macquarie, such as holders of our LLC interests. Macquarie’s compensation program endeavors to drive shareholder returns while managing risk in a prudent fashion by focusing on two main objectives: aligning the interests of staff and shareholders and attracting and retaining high quality staff.

We are asking our shareholders to indicate their support for our named executive officer compensation as described on pages 21 – 34 of this proxy statement, which includes the “Compensation Discussion and Analysis” section and the compensation tables and related narrative disclosure. This proposal, commonly known as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers.

The following resolution is submitted for a shareholder vote at the Annual Meeting:

“RESOLVED, that the shareholders of the Company approve, on a non-binding advisory basis, the compensation of the Company’s named executive officers as disclosed in the proxy statement for the 2012 Annual Meeting pursuant to Item 402 of Regulation S-K, including the “Compensation Discussion and Analysis” section and the compensation tables and related narrative discussion set forth in such proxy statement.”

This vote is advisory and, therefore is not binding on our Company. However, our Company values the opinions of our shareholders and will carefully consider, and will inform our Manager of, the outcome of this vote.

Recommendation of the Board

Our board recommends that you vote FOR the approval, on an advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement.

GOVERNANCE INFORMATION

Our board of directors, which we sometimes refer to as our board, is responsible for managing and directing the business and affairs of our Company. Our board of directors is responsible for establishing broad objectives and the general course of the business, determining basic policies, appraising the adequacy of our overall results, and generally representing and furthering the interests of our shareholders.

Board Leadership Structure

Our current board leadership structure comprises of a chairman and an alternate chairman, each of whom is not a member of management but is appointed by our Manager, and a lead director in accordance with our corporate governance guidelines. Currently, William Webb serves in this position. Our lead independent director presides at executive sessions of our independent directors, which occur at least quarterly and more often as our independent directors deem appropriate. Each of our board committees is chaired by and wholly comprised of an independent director. We believe that this leadership structure is appropriate at this time given our externally-managed corporate structure and the benefits that this structure provides to our shareholders by combining our Manager’s knowledge of infrastructure businesses with independent oversight of our Manager’s activities.

Our board’s chairman and alternate chairman are appointed by our Manager pursuant to the management services agreement. The chairman presides over meetings of the board of directors and meetings of shareholders, prepares the agenda for meetings of our board of directors with input from our other directors and performs such other duties as may be assigned by our board of directors. Our alternate chairman fulfills the duties of our chairman if he is absent. Because our chairman and alternate chairman are appointed by our Manager, but are not members of our management team, they are able to draw upon their extensive knowledge of infrastructure businesses and provide a strategic perspective on our business activities.

The following biographies highlight the qualifications and experience of Mr. Roberts, our chairman, and Mr. Stanley, our alternate chairman.

John Roberts has been a director of the Company since April 2004 and the chairman of the board of directors since December 2004. Mr. Roberts joined Macquarie in 1991 and is based in Sydney, Australia. He is Executive Chairman of the Macquarie Funds Group which has approximately U.S. $300 billion of capital under management and includes the activity of the Macquarie Infrastructure and Real Assets division (“MIRA”). Mr Roberts serves on the Boards and/or Investment Committees of a number of MIRA-managed specialist funds that own and manage interests in infrastructure, roads, airports, utilities, media, retirement facilities, private equity, industrial businesses and real estate. Previously, Mr. Roberts was Global Head of the Macquarie Capital Funds business (prior to it being renamed Macquarie Infrastructure and Real Assets). He was also previously Head of Europe and Joint Head of Macquarie Capital Advisers.

Mr. Roberts brings valuable business, strategic and operational expertise to our board of directors through his years of leadership within the Macquarie Group. As a result of his significant experience with managing infrastructure businesses and infrastructure funds, he is able to advise our board on industry trends and developments, identify business opportunities and risks and to actively participate in crafting our business strategy. As a highly regarded and well-known leader within the industry, Mr. Roberts’ service on our board enhances the reputation of the Company.

Martin Stanley has served as alternate chairman of the Company since April 2011. Mr. Stanley is Global Head of the Macquarie Infrastructure and Real Assets division, which manages a significant global portfolio invested in sectors including airports, roads, rail, utilities, renewable energy, telecommunications, industrials, property and media. These assets are owned through a variety of listed and unlisted funds and co-investment vehicles. He joined Macquarie in July 2004 to assist with fund raising for Macquarie’s first European Infrastructure Fund (MEIF) and to direct the acquisition and management of that fund’s infrastructure assets. He subsequently became Chief Executive Officer of MEIF and its two follow-on funds. Together, the three MEIF funds have combined equity under management of more than €7 billion. Mr. Stanley was integral to the development of Macquarie’s European infrastructure portfolio, including overseeing landmark investments such as the British gas distribution business, Wales & West Utilities Ltd; renewable energy operator, Energy Power Resources; the UK’s largest water company, Thames Water; French toll road operator, APRR; media transmission network, National Grid Wireless; the emergency service communication

10

network, Airwave; and German metering business, Techem AG. Prior to joining Macquarie, Mr. Stanley was a director at TXU Europe Group Plc, the energy services company whose operations included the generation, supply and trading of electricity and gas. Mr. Stanley has more than 20 years of experience in the utility sector having started his career in 1986 with Manweb Plc, the regulated asset owner and license holder for the power distribution network covering Merseyside, Cheshire and North Wales.

Mr. Stanley brings extensive knowledge of the infrastructure industry and its regulatory environment from his tenure in various leadership positions within the Macquarie Group. His understanding of the Group’s international operations and new business development makes him well-placed to provide strategic direction and industry insight to the Company. Mr. Stanley’s service on the investment committees of Macquarie Group managed vehicles affords him insight as to the valuation of infrastructure assets, their operations and key drivers in evaluating potential transactions.

Our Board’s Role in Risk Oversight

Our board of directors is responsible for overseeing our Company’s risk management. It discharges this responsibility directly and through its committees.

Our board of directors and its committees regularly review material enterprise, strategic, operational, legal and compliance risks with senior management of the Company and our Manager. Our board of directors is responsible for endorsing the Company’s risk management framework including key policies and procedures and approval of any changes to the framework or any key risk policies and procedures; monitoring compliance with the risk management framework and delegating authority to management, where appropriate. On a regular basis, the board is presented with risk and compliance reports from management and compliance personnel directly responsible for the identification, evaluation and monitoring of risks within the business.

As part of the monitoring process, the board or the appropriate committee is provided with the following information at scheduled board meetings: any proposed changes to the risk management framework; key policies and procedures or reporting arrangement for its approval; reports on exposures, non-compliance with key policies and general effectiveness of risk management system, as appropriate; results of independent reviews or audits of the control environment; and the relevant management information. While our board oversees risk management, the Company’s management is responsible for managing risk.

Our board of directors has delegated responsibility for the oversight of certain specific risks to the audit committee. The audit committee is responsible for an annual review of our Company’s policies with respect to risk assessment and risk management. The audit committee has primary responsibility for overseeing risk policies and processes relating to the financial statements and financial reporting, as well as overseeing management of our legal and regulatory risks and our compliance with applicable laws and regulations. Our audit committee is primarily responsible for assessing the adequacy our internal control framework including accounting and operational risk management controls based on information provided or obtained from management. Our audit committee is responsible for reviewing and monitoring our code of ethics and conduct to guard against significant conflicts of interest and dishonest, unethical or illegal activities. The audit committee periodically reviews the performance of the Company’s accounting and financial personnel and reviews material litigation and regulatory proceedings and other matters relating to potentially significant corporate liability with the Company’s general counsel.

Compensation Risk Assessment

The Company’s compensation committee does not have responsibility for reviewing the compensation of the Company’s executives, who are compensated by the Company’s Manager operating under the management services agreement. The compensation committee nonetheless believes that the Manager’s compensation policies and practices with respect to the Company’s executives do not encourage excessive risk-taking and are not reasonably likely to have a material adverse effect on the Company. In reaching this conclusion, the committee considered that the elements of compensation are balanced among current cash payments, deferred cash and equity awards, the time vesting requirements of the Macquarie profit share program, which help align the executives’ interests with those of long-term shareholders, the fact that compensation is based on financial performance and other measures including leadership and upholding Macquarie’s values, and the oversight by the board of directors of the executives’ actions.

11

Board Composition and Independence

Our board of directors consists of five directors, three of whom were elected by shareholders of the Company at the last Annual Meeting, and H.E. (Jack) Lentz, who was elected in August 2011 by our board to fill the vacancy when the board was expanded by one position. The remaining director, our chairman, currently John Roberts, is appointed by our Manager under the terms of our management services agreement. Martin Stanley was appointed as an alternate chairman by our Manager under the terms of the management services agreement in April 2011. Except for Messrs. Roberts and Stanley, all directors’ terms expire at this Annual Meeting.

The board is composed of a majority of independent directors. In accordance with the listing standards of the NYSE, to be considered independent, the board must affirmatively determine that a director has no material relationship with the Company, either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company, and that the director meets other NYSE independence standards. Mr. Webb maintains a private banking relationship with Macquarie Bank Limited, or MBL, an affiliate of our Manager, in an amount that is immaterial to MBL. In addition, Mr. Webb’s son worked for Macquarie in Sydney, Australia, in a position unrelated to our Company until 2009. The board has determined that these relationships are immaterial to a determination of director independence. Before Mr. Lentz retired from Lazard Freres & Co. in 2011, the Company paid Lazard Freres & Co. fees for services rendered primarily in 2010. The board has determined that this relationship is immaterial to a determination of independence. As a result, the board has determined that Messrs. Brown, Carmany, Lentz and Webb are independent under NYSE standards and Mr. Roberts and Mr. Stanley, as Mr. Roberts’ alternate, are not independent under the NYSE standards.

Board Meetings and Committees; Annual Meeting Attendance

Our board met thirteen times in total in 2011. All directors attended at least 98% of the combined board and committee meetings on which they served in 2011. In addition, it is the policy of our board that our directors are expected to use reasonable efforts to attend the Annual Meeting of Shareholders. All of our directors then in office participated in our 2011 Annual Meeting.

The LLC agreement gives our board the authority to delegate its powers to committees appointed by the board. All of our committees are composed solely of independent directors. Our committees are required to conduct meetings and take action in accordance with the directions of the board, the provisions of our LLC agreement and the terms of the respective committee charters. We have three standing committees: the audit committee, the compensation committee and the nominating and corporate governance committee. Copies of all committee charters, are available on our website at www.macquarie.com/mic under “Investor Center/Governance,” and in print from us without charge upon request by writing to Investor Relations at our principal executive offices at 125 West 55th Street, New York, New York 10019. The information on our website is not, and shall not be deemed to be, incorporated by reference into this proxy statement or incorporated into any other filings that the Company makes with the SEC.

Audit Committee.  Only directors who meet the independence requirements of the NYSE and Rule 10A-3 of the Securities Exchange Act of 1934 are members of the audit committee. The audit committee includes at least one “audit committee financial expert,” as required by applicable SEC regulations. The audit committee is responsible for, among other things:

Messrs. Brown, Carmany, Lentz and Webb serve on our audit committee, and the board has determined that both Mr. Brown and Mr. Carmany qualify as audit committee financial experts as defined by the SEC. The audit committee met seven times during 2011.

In accordance with the compensation committee charter, the members are “outside directors” as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended, and “non-employee directors” within the meaning of Section 16 of the Exchange Act. The responsibilities of the compensation committee include:

Our compensation committee may delegate any of its authority and duties described above to subcommittees or individual members of the committee, as it deems appropriate and in accordance with applicable laws and regulations. Additionally, our board of directors has adopted a policy pursuant to which it has delegated authority to make decisions relating to compensation plans and agreements (other than long-term incentive compensation or equity plans) to members of the Company’s senior management, or where appropriate, to the boards of directors of our individual businesses. This delegation of authority applies with respect to employees of our operating businesses, who are not members of the Company’s senior management.

Messrs. Brown, Carmany, Lentz and Webb serve on our compensation committee. The compensation committee met six times during 2011.

Nominating and Corporate Governance Committee.  Only directors who meet the independence requirements of the NYSE are members of the nominating and corporate governance committee. The nominating and corporate governance committee is responsible for, among other things:

14

Compensation Committee Interlocks and Insider Participation

Messrs. Brown, Carmany, Lentz and Webb are members of our compensation committee. None of the members of our compensation committee is, or has been, an employee of the Company. During 2011, no member of our compensation committee had any relationship with the Company requiring disclosure under Item 404 of Regulation S-K. None of the Company’s executive officers or members of the Company’s board of directors has served as a member of a compensation committee (or if no committee performs that function, the board of directors) of any other entity that has an executive officer serving as a member of the Company’s board of directors or compensation committee.

Director Retirement Policy

The board adopted a director retirement policy in 2011 pursuant to which a director must tender his or her resignation upon reaching the age of 75, to be effective upon the first annual shareholder meeting following such director’s birthday. The age limit is not subject to waiver by the board.

Executive Sessions of Our Board

Our corporate governance guidelines provide that the non-management directors will meet without management directors at regularly scheduled executive sessions at least quarterly and at such other times as they deem appropriate. To the extent that any non-management directors are not independent, the independent directors will meet in regularly scheduled executive sessions at least once annually. In accordance with our corporate governance guidelines, the lead independent director, or alternatively, the chairman of the audit committee, nominating and corporate governance committee or compensation committee, will preside at these executive sessions of the non-management directors as determined by the non-executive directors based upon the subject matter to be discussed. Mr. Webb presided, and continues to preside, over these sessions. Our non-management directors met more than quarterly during 2011.

Corporate Governance Guidelines and Code of Ethics and Conduct

Our board has adopted corporate governance guidelines that set forth our corporate governance objectives and policies and govern the functioning of the board. We also have a code of ethics and conduct that sets forth our commitment to ethical business practices. Our code of ethics and conduct applies to our directors, officers and employees, including our chief executive officer and chief financial officer, and also applies to our Manager, its employees and any affiliates of our Manager that perform management services for us pursuant to the management services agreement.

Our corporate governance guidelines and our code of ethics and conduct are available on our website at www.macquarie.com/mic under “Investor Center/Governance” and in print from us without charge upon request by writing to Investor Relations at Macquarie Infrastructure Company LLC, 125 West 55th Street, New York, New York 10019.

Minimum Shareholding Guidelines

Our board, upon the recommendation of our nominating and corporate governance committee, has adopted stock ownership guidelines to align the interests of our non-management directors with the interests of our shareholders. Non-management directors are required to hold LLC interests with a value equal to $300,000, based on the closing price of the LLC interests on the NYSE on the later of the date of adoption of the policy and the date such director is first elected or appointed to the board. Non-management directors have up to five years to meet these requirements provided that LLC interests with a value of at least $50,000 should be owned within the first year. Our non-management directors are each in compliance with this policy.

Nominations of Directors

As provided in its charter, the nominating and corporate governance committee will identify and recommend to the board nominees for election or re-election to the board. The committee will review candidates for the board recommended by the Company’s management and other members of the board who are not members of the committee, as well as candidates recommended by shareholders, in accordance with the following criteria and as discussed in “Shareholder Nominations of Directors” below.

15

The nominating and corporate governance committee, in making its recommendations, may consider some or all of the following factors, among others:

• monitoring developments in the law and practice of corporate governance;

• the candidate’s judgment, skill, diversity and experience with other organizations of comparable purpose, complexity and size, and subject to similar legal restrictions and oversight;

• the relationship of the candidate’s experience to the experience of other board members;

• the extent to which the candidate would be a valuable addition to the board and any committees thereof;

• whether or not the person has any relationships that might impair his or her independence, including any business, financial or family relationships with the Manager or the Company’s management; and

• the candidate’s ability to contribute to the effective management of the Company, taking into account the needs of the Company and such factors as the individual’s experience, perspective, skills, and knowledge of the industry in which the Company operates.

Our nominating and corporate governance committee aims to achieve a board of directors that, as a whole, provides effective oversight of the management and business of our Company. Therefore, the committee believes that our directors should represent an appropriate diversity of experience, expertise, skills, specialized knowledge and other qualifications and attributes that provide for a variety of viewpoints. We believe that a director nominee should not be chosen or excluded solely or largely because of race, ethnicity, gender, age, national origin, or sexual orientation or identity.

In recommending candidates for election as directors, the nominating and corporate governance committee will also take into consideration the need for the board of directors to have a majority of directors that are independent under the requirements of the NYSE and other applicable laws, and at least three directors that are independent under these requirements.

In addition, the nominating and corporate governance committee will recommend candidates for election as directors based on the following criteria and qualifications:

• Financial Literacy.  Such person should be “financially literate” as such qualification is interpreted by the board of directors in its business judgment.

• Leadership Experience.  Such person should possess significant leadership experience, such as experience in business, finance/accounting, law, education or government, and shall possess qualities reflecting a proven record of accomplishment and ability to work with others.

• Commitment to Our Company’s Values.  Such person shall be committed to promoting our financial success and preserving and enhancing our reputation as a leader in the infrastructure sector, and shall be in agreement with our values as embodied in our code of ethics and conduct.

• Absence of Conflicting Commitments.  Such person should not have commitments that would conflict with the time commitments of a director of our Company.

• Complementary Attributes.  Such person shall have skills and talents which would be a valuable addition to the board and any committees thereof and that shall complement the skills and talents of our existing directors.

• Reputation and Integrity.  Such person shall be of high repute and integrity.

Under the corporate governance guidelines, directors must inform the chairman of the board and the chairman of the nominating and corporate governance committee in advance of accepting an invitation to serve on another public company board or any committee thereof. In addition, no director may sit on the board, or beneficially own more than 5% equity interest in (other than through mutual funds or similar non-discretionary, undirected arrangements) any competitor of the Company in our principal lines of business.

16

Shareholder Nominations of Directors

To make a director nomination, a shareholder must give written notice to our Secretary at our principal executive office at 125 West 55th Street, New York, New York 10019. To be considered for inclusion in our proxy statement for the 2013 Annual Meeting of Shareholders, shareholder nominations must be received by the Company no later than January 31, 2013 and no earlier than January 1, 2013.

When directors are to be elected at a special meeting, such notice must be given not earlier than the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which a public announcement is first made of the date of the special meeting and of the nominees proposed by the board to be elected at such meeting.

In addition to any other requirements, for a shareholder to properly bring a nomination for director before either an annual or special meeting, the shareholder must be a shareholder of record on both the date of the shareholder’s notice of nomination and the record date relating to the meeting.

The shareholder submitting the recommendation must submit:

• the shareholder’s name and address as they appear on the share register of the Company, as well as the name and address of the beneficial owner, if any, on whose behalf the nomination is made;

• the number of LLC interests which are owned beneficially and of record by such shareholder and such beneficial owner, if any; and

• a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons pursuant to which the recommendation is being made by the shareholder.

In addition, any such notice from a shareholder recommending a director nominee must include the following information:

• the candidate’s name, age, business address and residence address;

• the candidate’s principal occupation or employment;

• the number of LLC interests that are beneficially owned by the candidate;

• a copy of the candidate’s resume;

• a written consent from the candidate to being named in the proxy statement as a nominee and to serving as director, if elected; and

• any other information relating to such candidate that would be required to be disclosed in solicitations of proxies for election of directors under the federal securities laws, including Regulation 14A of the Securities Exchange Act of 1934, as amended.

We may require any proposed nominee to furnish any additional information that we reasonably require to enable our nominating and corporate governance committee to determine the eligibility of the proposed nominee to serve as a director. Candidates are evaluated based on the standards, guidelines and criteria discussed above as well as other factors contained in the nominating and corporate governance committee’s charter, our corporate governance guidelines, other of our policies and guidelines and the current needs of the board.

Brown, Carmany and Webb were each granted 5,975 director LLC interest units, resulting in an aggregate grant of 17,925 director LLC interest units. These director LLC interest units, which equal $150,000 per director divided by the average closing price for the ten days preceding the grant date, being $25.10 per director LLC interest unit, vest on the day immediately preceding our 2012 Annual Meeting of shareholders. Upon vesting of the director LLC interest units, each director has the right to receive 5,975 LLC interests, which had a market value of $167,001 based on the per share closing price on the NYSE of our LLC interests on December 31, 2011.

(3) Effective August 12, 2011, Mr. Lentz was elected as a director to serve until our 2012 Annual Meeting of shareholders. Mr. Lentz was granted 5,209 director LLC interest units. These director LLC interest units, the amount of which was based on the annual $150,000 director grant, pro rated for the period from the date of our 2011 Annual Meeting to that date of election, and divided by the average closing price for the ten days preceding the date of election, being $23.21 per director LLC interest unit, vest on the day immediately preceding our 2012 Annual Meeting of shareholders. Upon vesting of the director LLC interest units, Mr. Lentz has the right to receive 5,209 LLC interests, which had a market value of $145,592 based on the per share closing price on the NYSE of our LLC interests on December 31, 2011.

The above are the only equity grants by the Company to directors that were outstanding at December 31, 2011. We do not compensate our chairman or our alternate chairman for their services on our board of directors.

Director Fees

Our directors eligible for election by our shareholders each receive annual cash retainers of $50,000 for service on the board, payable in equal quarterly installments, as well as cash compensation for attendance at committee meetings and an annual retainer for service as committee chairman. The independent directors’ equity plan provides for automatic, non-discretionary awards of director LLC interest units as an additional fee for the independent directors’ services on the board. Directors (including the chairman and the alternate chairman appointed by our Manager) are reimbursed for reasonable out-of-pocket expenses incurred in attending meetings of the board of directors or committees and for any expenses reasonably incurred in their capacity as directors and alternate chairman, respectively. The Company also reimburses directors for all reasonable and authorized business expenses in accordance with the policies of the Company as in effect from time to time.

19

Messrs. Brown, Carmany and Webb have been directors since the closing of our initial public offering in December 2004 and Mr. Lentz was appointed as a director effective August 12, 2011. Each member of the Company’s various standing committees also receives the following compensation related to service on these committees:

• for attending a committee meeting in person (if any): $3,000 for each meeting of the audit committee; $2,000 for each meeting of the nominating and corporate governance committee; and $2,000 for each meeting of the compensation committee; and

• for attending a telephonic committee meeting (if any): $1,500 for each meeting of the audit committee; $1,000 for each meeting of the nominating and corporate governance committee; and $1,000 for each meeting of the compensation committee.

The chairperson of the audit committee, nominating and corporate governance committee and compensation committee also receive an annual cash retainer, payable in equal quarterly installments, of $5,000, $2,000 and $2,000, respectively.

Independent Directors’ Equity Plan

The Company’s independent directors’ equity plan provides for automatic, non-discretionary awards of director LLC interest units as an additional fee for the independent directors’ services on the board. The purpose of this plan is to promote the long-term growth and financial success of the Company by attracting, motivating and retaining independent directors of outstanding ability.

Only independent directors may participate in the plan. Four of our directors, Messrs. Brown, Carmany, Lentz and Webb, are eligible to participate in the plan. The chairman of the board of directors administers the plan. If the chairman is eligible for any awards under the plan, the plan will be administered by the most senior member of the board with respect to length of service who is not eligible for any awards under the plan. The administrator has the authority to adopt rules and regulations that he or she considers necessary or appropriate to carry out the purposes of the plan and to interpret the plan. The administrator may also delegate some or all of his or her authority under the plan to an officer of the Company.

On June 2, 2011, Messrs. Brown, Carmany and Webb each received 5,975 director restricted LLC interest units and on August 12, 2011, Mr. Lentz received 5,209 director restricted LLC interest units, which was calculated as 5,975 director LLC interest units pro rated from the date of our 2011 Annual Meeting to that date of election. These units will vest on the day immediately preceding the 2012 Annual Meeting. In addition, each independent director nominee will be eligible to receive, upon election at the 2012 Annual Meeting, a grant of director LLC interest units equal to $150,000 divided by the average of the closing price on the NYSE of one LLC interest during the ten-day period immediately preceding the date of our 2012 Annual Meeting. Generally, units granted at each Annual Meeting of shareholders will vest (assuming continued service of the director) on the day immediately preceding the next Annual Meeting of shareholders held following the date of grant.

If a director’s service on the board terminates by reason of death or disability or in the event of a business combination (as defined in the Company’s LLC agreement) of the Company during the director’s service, the director LLC interest units will vest immediately.

We credit director LLC interest units to a bookkeeping account. No interest or dividends accrue or are credited to any director LLC interest units or the director’s account. As soon as practical following vesting, we will settle director LLC interest units by delivering to the director the equivalent whole number of LLC interests. Units cannot be settled in cash or any other kind of consideration. Prior to settlement, directors do not have the rights of a shareholder in any LLC interest corresponding to the director units.

The plan will expire on December 15, 2014, which is the tenth anniversary of the date on which the plan was approved by shareholders. The administrator may amend or terminate the plan at any time. However, the administrator may not amend the plan without a director’s consent if the amendment would adversely affect the director’s rights to previously granted awards.

COMPENSATION DISCUSSION AND ANALYSIS

General

Our Company has a management services agreement with our Manager, a member of the Macquarie Group. The management services agreement defines our Manager’s duties and responsibilities and is subject to the oversight and supervision of our Company’s board of directors. Our Manager is responsible for the conduct of our Company’s day-to-day business and affairs and is entitled to receive base and potentially performance fees for the provision of its services. These fees are set forth below under “Certain Relationships and Related Party Transactions.” The Macquarie employees who serve as our chief executive officer and our chief financial officer have been assigned, or seconded, to us by our Manager and they have a fiduciary duty to act in the best interests of our Company. While these employees derive profit share allocations from Macquarie, there is a strong alignment of interest between these employees and our shareholders for the following reasons:

• Our Company pays management and potentially performance fees to Macquarie in accordance with the management services agreement. Management fees are linked to market capitalization of our Company and performance fees can be paid based on the ongoing out-performance of our Company relative to a utilities benchmark.

• Macquarie holds a significant interest in our Company and from time to time has reinvested its fees in our Company’s LLC interests. At March 31, 2012, Macquarie had a 9.7% interest in our Company.

• The staff of Macquarie Group understands that the relationship with Macquarie-managed entities is a long-term and recurring one and important to Macquarie’s welfare as a whole. They take a long-term approach to adding value in connection with the managed entities rather than solely focusing on the fees that would result from any one transaction.

• The compensation system adopted by Macquarie, discussed in detail below, links the compensation of our executive officers to our performance.

We do not pay any compensation to our executive officers. Instead, we pay our Manager the management fees and potentially performance fees discussed above. The Company does not have any employees. James Hooke, our chief executive officer and a Macquarie executive director, and Todd Weintraub, our chief financial officer and a Macquarie division director, are employed by Macquarie and are seconded to us on a full-time basis. Under our management services agreement, the services performed for the Company by our Manager are provided at its expense, including all of the compensation of our seconded executive officers. Messrs. Hooke and Weintraub are our only named executive officers.

James Hooke was appointed as our chief executive officer effective May 9, 2009, but joined Macquarie effective September 17, 2007. Todd Weintraub has served as our chief financial officer since November 25, 2008. The purpose of this compensation discussion and analysis is to provide our investors with information about the components of the compensation paid to our executive officers by Macquarie, and the policies and objectives served by Macquarie’s compensation program.

Objectives of Macquarie’s Compensation Program

The elements of the compensation program for our executive officers are derived from the general program established for employees of Macquarie. Macquarie’s approach to compensation is designed to drive shareholder returns over the long term, both for Macquarie shareholders as well as for shareholders of the entities managed by Macquarie including holders of our LLC interests. Macquarie’s compensation program endeavors to drive shareholder returns while managing risk in a prudent fashion by focusing on two main objectives. The first objective is to attract and retain high quality staff. The second objective is to align the interests of staff and shareholders by motivating staff through its compensation policies to increase Macquarie’s net profit after tax and sustain a high relative return on capital while managing risk. Growing net profit after tax and sustaining a high return on capital are fundamental drivers of total shareholder returns for Macquarie shareholders. These twin objectives encourage executives to expand existing businesses and establish promising new activities.

21

Fees derived from entities managed by Macquarie represent part of Macquarie’s net profit after tax. Management fees earned by Macquarie under our management services agreement are based on the market capitalization of our Company and performance fees are based on ongoing out-performance over a utilities benchmark. As a result, incentives designed to drive Macquarie’s net profit after tax also serve to align the interests of our executive officers with those of our shareholders.

Macquarie also endeavors to attract high quality executives and to retain them by offering a competitive performance-driven compensation package that encourages long-term commitment to Macquarie and Macquarie-managed entities and to superior performance. We believe that our ongoing performance is critically dependent on the skill, experience and caliber of Macquarie’s team of experienced executives, such as our executive officers, for whose services Macquarie must compete in the world’s major financial centers.

Six key principles in Macquarie’s compensation approach assist with the objective of driving shareholder returns by aligning the interests of staff and shareholders and by attracting and retaining high quality staff are:

• Ensuring compensation arrangements are competitive on a global basis with Macquarie’s international peers;

• Emphasizing performance-based remuneration with an appropriate balance between short and longer-term incentives having regard to risk. In the case of our executive officers, performance is assessed with reference to the performance of our Company, including the performance of our underlying businesses;

• Linking rewards to create sustainable shareholder value through the use of shareholder return drivers, namely Macquarie’s profitability and returns in excess of the cost of capital, which is linked to our market performance through the calculation of the management and performance fees;

• Using equity to create alignment with shareholder interests;

• Using consistent arrangements over time to ensure staff are confident that efforts over multiple years will be rewarded; and

• Designing retention mechanisms to encourage a long-term perspective and hence alignment with shareholders.

Responsibility for Macquarie’s Compensation Program

The board of directors of Macquarie, or the Macquarie board, has a Board Remuneration Committee, or the BRC, whose objective is to assist the Macquarie board with Macquarie’s compensation policies and practices. The BRC approves all individual compensation and profit share recommendations for executive directors, including James Hooke, all individual promotion equity grants to staff, other compensation recommendations made outside of Macquarie’s policy relating to individuals or groups of individuals (unless required to be approved by the Macquarie board), material changes to pension arrangements and changes to compensation policies not requiring full Macquarie board approval.

Responsibility for the determination of individual compensation and profit share recommendations for division and associate directors, including Todd Weintraub, for the 2011 remuneration cycle rests with the Head of the Macquarie Financial Management Group. These recommendations are subject to review by Macquarie’s Remuneration and Promotions Committee, a committee of Macquarie management. The recommendations are ultimately approved by the BRC, individually in the case of promotion equity grants and in the aggregate in the case of fixed remuneration changes and profit share allocations.

Based on a review of the analyses and conclusions regarding compensation provided by the BRC in 2011, the non-executive directors of the Macquarie board determined that compensation was appropriate and that it was structured in a way that encouraged the overall objective of driving longer-term shareholder returns of Macquarie by aligning the interest of staff with those of shareholders and by attracting and retaining high-quality staff.

22

2011 Say-on-Pay Advisory Vote

Approximately 96.1% of the votes cast approved, on an advisory basis, the executive compensation described in the Company’s proxy statement for such meeting. There were no changes to the structure of the Company’s executive compensation program as a result of the say-on-pay vote.

Elements of Macquarie’s Compensation Program

Macquarie’s executive compensation program consists of two elements: fixed compensation and annual profit share. We describe each of these below.

Fixed Compensation

Fixed compensation for our named executive officers consists of annual base salary. It also includes the following additional benefits that Macquarie believes are customarily provided by employers in the United States: life insurance, accidental death, disability and dismemberment (AD&D) insurance, long-term and short-term disability insurance, medical, dental and vision coverage and matching employer contributions under Macquarie’s 401(k) retirement plan.

Annual base salary takes into consideration the role of the individual and market conditions. However, fundamental to Macquarie’s compensation philosophy is the principle that a significant amount of the compensation be at risk and dependent upon performance. Mr. Hooke’s annual base salary remained at $400,000 in 2011.

Mr. Weintraub’s annual base salary increased on July 1, 2011 from $275,000 to $325,000. In determining Mr. Weintraub’s 2011 base salary, factors that were considered included the scope and responsibilities of his role relative to other public company CFOs of similar size and complexity.

Annual Profit Share

Macquarie has profit share arrangements for staff, including Mr. Hooke and Mr. Weintraub, to encourage superior performance. Each year, the size of the profit share pool is determined by reference to Macquarie’s net profit after tax and excess return over the cost of capital for the period from April 1st of the prior year to March 31st of the year in which the profit share is determined. The proportion of after tax profit and the proportion of earnings in excess of Macquarie’s cost of capital that are incorporated in the profit share calculation are reviewed at least annually. The profit share pool is allocated to business groups based primarily on their relative contributions to profit, taking into account capital usage and risk.

An individual’s profit share allocation is based on performance. For staff with specific fund responsibilities, the performance of the relevant fund is important in determining that individual’s profit share allocation, including the underlying factors influencing fund performance such as management and leadership, the operational performance of the underlying assets and effective capital management. The effect of this profit sharing is to provide substantial incentives in relation to superior performance, but low or no participation for less satisfactory performance. Superior performance looks at a range of indicators that go beyond financial performance, including leadership and upholding Macquarie’s goals and values. For senior executives, this means that a large part of their remuneration each year is performance-based and “at risk,” providing significant alignment of their interests with those of Macquarie shareholders and, through the fee incentives in our management services agreement, our shareholders.

Our executive officers participate in the profit share pool. The profit share pool allows Macquarie to reward all staff who have contributed to the growth of Macquarie-managed entities. The profit share pool also creates incentives for, and encourages long-term commitment among, executives working in the interests of Macquarie-managed entities that may experience some short-term market underperformance or other short-term declines in profitability due to macroeconomic factors or other extraordinary circumstances, even though the underlying assets may be performing well.

23

The level of profit share received by our executive officers is based predominantly on their individual contribution to the performance of our Company, taking into account the following elements:

• operational performance of our underlying businesses;

• management and leadership of our Company and the businesses under the control of our Company;

• acquisitions and the subsequent management of those businesses to ensure performance is in line with the acquisition business plans;

• effective capital management; and

• factors relating to enhancing Macquarie’s and the Company’s reputation and track record.

There is no formulaic approach to determining our executive officers’ share of the profit share pool. It is completely discretionary and is determined based upon the recommendation of the Head of the Macquarie Funds Group in the case of Mr. Hooke and the head of the Macquarie Financial Management Group in the case of Mr. Weintraub, taking into account the factors outlined above as well as input from the Company’s directors regarding the performance of our executive officers. Our executive officers’ profit share is determined with respect to Macquarie’s fiscal years ended March 31st of each year and therefore does not reflect subsequent events or our performance for the remainder of each calendar year.

Mr. Hooke’s profit share for 2011 was $1,500,000, of which $900,000 was paid in cash and $600,000 was retained, with $300,000 notionally invested in the Directors’ Profit Share Plan (“DPS Plan”) and $300,000 delivered in the form of Macquarie shares through the Macquarie Group Employee Retained Equity Plan (“MEREP”). The specific factors considered in determining Mr. Hooke’s profit share reflected the performance during the period of our LLC interests compared to utilities index benchmarks, the growth in available cash in our underlying businesses, the effective management and leadership of the operation of our Company and our underlying businesses, continued debt reduction and improved leverage ratio at Atlantic Aviation and his role as director of IMTT. Recommendations also took into account Mr. Hooke’s role in maintaining and growing the reputation and brand awareness of the Company and Macquarie as a leading manager and owner of infrastructure investments in North America.

Mr. Weintraub’s profit share for 2011 was $400,000, of which $292,868 was paid in cash and $107,132 was retained and subsequently delivered in the form of Macquarie shares through the MEREP. The specific factors considered in determining Mr. Weintraub’s profit share for 2011 include his leadership of the finance function of our Company, including his management and coordination of internal controls over financial process and management of the internal and external audit function, his development and leadership of our finance team and the finance teams of our operating businesses, coordination and management of compliance with the United States Securities and Exchange Commission’s requirements for regular reporting, as well as his stewardship of the Company’s accounting function, including staff management, identification and resolution of accounting issues and implementation of and compliance with new accounting standards. In addition, Mr. Weintraub’s profit share reflected his leadership and overall management of debt reduction and improved leverage ratio at Atlantic Aviation and his role as director of IMTT.

24

Retained Portion of Profit Share

Deferral and restriction arrangements apply to a portion of allocated profit share to encourage a long-term perspective and commitment from Macquarie employees, including our executive officers. It also encourages alignment with the longer-term interest of shareholders.

The table below sets out a summary of the current arrangements. The rules for executive and division directors apply to Mr. Hooke and Mr. Weintraub’s profit share allocations, respectively, for Macquarie’s fiscal year ended March 31, 2011.

Key Area	Executive Directors	Division Directors
Amount of profit share retained	40% in 2010 and 40% – 70% in 2011	AUD $0 – AUD $50,000	Nil
		AUD $50,000 – AUD $200,000	25%
		AUD $200,000 – AUD $500,000	35%
		Above AUD $500,000	40%
How retained profit share is invested	• Invested in a combination of Macquarie shares (MEREP) and notionally invested in a portfolio of Macquarie- managed funds (DPS Plan)	Invested in Macquarie shares (MEREP)
	•   Investment mix will vary depending on individual’s role
Vesting and release of retained profit share	All retained amounts vest and are released from three to five years for profit share retained from 2010 and on (see also forfeiture below)	Vesting and release two to four years after the year retained
Forfeiture of retained profit share on leaving	• Unvested amounts forfeited, except for limited circumstances	Unvested amounts forfeited, except on the grounds of redundancy, death, total and permanent disability and other limited exceptional circumstances
	•   Vested amounts forfeited in stages if a “disqualifying event” occurs within two years of leaving
Minimum Shareholding Requirement	Required to hold the deemed after-tax equivalent of 10% of all profit share allocations over the last five years in Macquarie shares (which is satisfied by the above requirements).	Not applicable.

Retained profit share is held for executive directors in both the DPS Plan and the MEREP. For division directors, retained profit share is held solely in the MEREP. The features of these plans and details of 2011 retention for Mr. Hooke and Mr. Weintraub under each plan are outlined below.

The Directors’ Profit Share (“DPS”) Plan

The DPS Plan comprises exposure to a notional portfolio of Macquarie-managed funds. These retained amounts for executive directors are notionally invested over the retention period. This investment is described as “notional” because executive directors do not directly hold securities in relation to this investment. However, the value of the retained amounts will vary as if these amounts were directly invested in actual securities, giving the executive directors an effective exposure to the performance of the securities. Mr. Hooke was promoted to the position of executive director effective July 1, 2010 and therefore $300,000 of his 2011 retention was notionally invested in the DPS Plan.

25

The Macquarie Group Employee Retained Equity Plan (“MEREP”)

The role of the MEREP is to deliver remuneration in the form of Macquarie Group Limited equity (ASX:MQG). Equity awards through the MEREP, in the U.S., will generally be in the form of units comprising a beneficial interest in Macquarie shares held in a trust for staff members in the form of restricted share units. The participant is entitled to receive dividends on the shares and direct the Trustee how to exercise voting rights on the shares.

As noted above, profit share retention arrangements via the MEREP apply to (up to and including 2011), executive and division directors, including Mr. Hooke and Mr. Weintraub, respectively. Of the 2011, 2010 and 2009 profit share for Mr. Hooke, $300,000, $113,527 and $26,270 was retained and invested in Macquarie shares through the MEREP, respectively. Of the 2011, 2010 and 2009 profit share for Mr. Weintraub, $107,132, $20,777 and $11,270 was retained and invested in Macquarie shares through the MEREP, respectively. The reasons for the increase from 2010 to 2011 are the same for Mr. Hooke and Mr. Weintraub, which are discussed under “Elements of Macquarie’s Compensation Program- Fixed Compensation and Annual Profit Share” above. These equity awards through the MEREP will vest and be released on the first day of the first staff trading window after July 1st following the second, third and fourth anniversary of the initial profit share allocation for Mr. Weintraub and for Mr. Hooke’s profit share earned before 2011. Mr. Hooke’s profit share earned in 2011 will vest and be released on the first day of the first staff trading window after July 1st following the third, fourth and fifth anniversary of the initial profit share allocation.

In addition, 4,000 restricted share units were granted to Mr. Hooke through the MEREP in 2010 for his promotion to the position of executive director and 1,500 restricted share units were granted to Mr. Weintraub through the MEREP in 2010 for his promotion to the position of division director. For further discussions on retained profit share and MEREP awards, see “Executive Compensation — Grants of Macquarie Restricted Share Units” below.

Profit share retained pre-2009 will continue to be held in cash and vests and is paid out in three equal installments: two, three and four years from the retention date. Notional interest is paid on retained profit share. In the event that an employee ceases employment with Macquarie, any retained profit share allocation that has not vested to them is forfeited, except at the discretion of the board, the BRC or the Executive Committee on delegation from the BRC.

Post-Termination Compensation and Benefits

On May 24, 2010, Macquarie Capital Group Limited entered into an employment agreement with Mr. Hooke. The employment agreement provides that he holds the position of executive director. Mr. Hooke is assigned to Macquarie Holdings (USA) Inc. and is currently seconded to Macquarie Infrastructure Company LLC as chief executive officer. On May 26, 2010, Macquarie Holdings (USA) Inc. entered into an employment agreement with Mr. Weintraub. The employment agreement provides that he holds the position of division director. Mr. Weintraub is assigned to Macquarie Holdings (USA) Inc. and currently seconded to Macquarie Infrastructure Company LLC as chief financial officer. See “Executive Compensation —  Employment Agreements” below for further discussions.

The employment agreements with our current executive officers are ongoing and provide for termination of employment by Macquarie or the executive after giving four weeks’ notice for Mr. Hooke and two weeks’ notice for Mr. Weintraub. Macquarie sponsors a severance plan for U.S.-based staff that it believes is comparable to plans typically offered by U.S. employers. The MEREP, DPS Plan, Macquarie’s profit share arrangements and the Macquarie Group Employee Share Option Plan also have specific provisions relating to termination events as described under “Executive Compensation — Potential Payments on Termination or Change in Control” below.

26

COMPENSATION COMMITTEE REPORT

Our compensation committee is composed of four independent directors. In addition, all members of the compensation committee are “outside directors” for purposes of Section 162(m) of the Internal Revenue Code, as amended, and “non-employee directors” within the meaning of Section 16 of the Exchange Act. The responsibilities of the compensation committee include reviewing the Manager’s performance of its obligations under the management services agreement, reviewing the remuneration of the Manager, determining the compensation of the independent directors, granting rights to indemnification and reimbursement of expenses to the Manager and any seconded individuals and making recommendations to the board regarding the Company’s equity-based and incentive compensation plans, policies and programs. The compensation committee operates under a written charter adopted by the board, reflecting the NYSE rules for compensation committees in light of the Company’s external management structure. A copy of the charter is available on the Company’s website at www.macquarie.com/mic under “Investor Center/Governance.”

As described in the section “Director Compensation Fiscal Year 2011” in this proxy statement, our directors receive an annual cash retainer for serving on the board, fees for each committee meeting which they attend and an annual cash retainer for each committee they chair. In addition, independent directors are compensated with director LLC interest units that are granted under our independent directors’ equity plan and receive reimbursement for certain reasonable expenses related to their service as directors.

The compensation committee does not establish or review compensation policies with respect to our chief executive officer or chief financial officer since such individuals are employed by an affiliate of the Manager, and are seconded to the Company.

This report on executive compensation for 2012 is provided by the undersigned members of the compensation committee of the board.

The compensation committee has reviewed and discussed the Compensation Discussion and Analysis with the Company’s management. Since the Company’s named executive officers are not employed or compensated by the Company, the Compensation Discussion and Analysis reflects a discussion of the compensation elements and objectives of the Macquarie Group rather than the Company. Based on this review and discussion, the compensation committee has recommended to the board, and the board has approved, the inclusion of the Compensation Discussion and Analysis in this Proxy Statement and its incorporation by reference into the Company’s annual report on Form 10-K for the year ended December 31, 2011.

	Members of the Compensation Committee William H. Webb, Chairman Norman H. Brown, Jr. George W. Carmany, III H.E. (Jack) Lentz

The information contained in the report above shall not be deemed to be “soliciting material” or to be “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Exchange Act or the Securities Act of 1933, as amended, or the Securities Act, except to the extent that we specifically incorporate it by reference in such filing.

In addition to the $20,777 that was retained during 2010, 1,500 restricted share units were granted to Mr. Weintraub through the MEREP for his promotion to the position of division director.

Nonqualified Deferred Compensation in Fiscal Year 2011

The following table sets forth a summary of the profit share retained pre-2009 of each named executive officer and in the case of Mr. Hooke, the amount retained in 2011 under the DPS Plan as of December 31, 2011.

Name	Plan			Registrant Contributions in Last FY ($)(1)		Aggregate Earnings in Last FY ($)(2)		Aggregate Withdrawals/ Distributions ($)		Aggregate Balance at Last FYE ($)(3)
James Hooke		DPS Plan			300,000		4,023		—		304,023
		Retained profit share held in cash	(4)		—		485		25,991		25,579
Todd Weintraub		Retained profit share held in cash	(4)		—		292		21,176		12,987

(1) Consists of the portion of the amount reported in the bonus column of the Summary Compensation Table for the 2011 fiscal year that is deferred under the DPS Plan for Mr. Hooke.

(2) With respect to the DPS Plan, amount represents notional earnings (losses) from July 1, 2011 to December 31, 2011 and the foreign exchange adjustment at December 31, 2011. The amounts have been converted from Australian dollars to U.S. dollars using the Federal Reserve Bank noon buying rate effective on December 31, 2011 of $1.0251 to AUD $1.00. With respect to the retained profit share held in cash, amounts represent the aggregate earnings accrued during 2011 on profit share retained pre-2009.

(3) With respect to the DPS Plan, the amount has been converted from Australian dollars to U.S. dollars using the Federal Reserve Bank noon buying rate effective on December 31, 2011 of $1.0251 to AUD $1.00.

(4) Retained profit share held in cash represents profit share retained pre-2009 before the establishment of the MEREP for both Mr. Hooke and Mr. Weintraub.

The compensation reported in the nonqualified deferred compensation table was deferred by Mr. Hooke and Mr. Weintraub pursuant to Macquarie’s profit share arrangements. Under the DPS Plan, the value of the retained DPS for the period from the preceding July 1st to June 30th is determined based on total shareholder returns of the notional portfolio of Macquarie-managed funds selected by Macquarie assuming reinvestment of distributions and, therefore, takes into account both capital appreciation and distributions to shareholders. Notional earnings (losses) for the July 1st to June 30th period are measured quarterly. The participant has no input into decisions regarding the notional portfolio selected. Any increases in value of the notional portfolio may be paid out in August each year at the discretion of Macquarie’s Executive Committee, or the BRC. If the notional investment of the amount retained under the DPS Plan results in a notional loss, Macquarie will not make any payment or compensation in respect of the loss. This notional loss will be offset against notional income in the first instance and then against any future notional income until the loss is completely offset. Any notional loss may also be deducted from amounts retained under the DPS Plan at the discretion of the Macquarie Executive Committee or the BRC. Notional interest is paid on pre-2009 retained profit share held in cash based on the one year guaranteed U.S. dollar cash rate.

32

Profit share retained under the DPS Plan vests and is paid out in three equal installments: three, four and five years from the retention date. Profit share retained pre-2009 will continue to be held in cash and vests and is paid out in three equal installments: two, three and four years from the retention date.

Potential Payments on Termination or Change in Control

For each of the named executive officers, there are no contracts, agreements, plans or arrangements that provide for payments upon a change of control of our Company.

Termination Provisions Under Employment Agreements

Under the terms of Mr. Hooke’s employment agreement with MGL, dated May 24, 2010, Mr. Hooke will provide Macquarie Holdings (USA) Inc. four weeks’ notice if he voluntarily resigns. Macquarie Holdings (USA) Inc. will provide Mr. Hooke four weeks’ notice of any termination (although the employer may make payments to him in lieu of such notice), subject to certain exclusions including misconduct, dishonesty, harm to reputation of the employer or Macquarie, inappropriate workplace behavior, inability to comply with conditions of employment and/or any other reason justifying termination without notice. The period between such notice and termination of employment is referred to as the “notice period.” During the notice period, Mr. Hooke will be entitled to continue to receive his salary and contributions to the group medical, dental, vision, life and disability plans. Upon termination, Mr. Hooke will be entitled to payment of any accrued but unpaid vacation time. During the notice period, Macquarie Holdings (USA) Inc. has the discretion to direct Mr. Hooke not to do any work or contact any customers or clients for a period up to the date of his termination or resignation. During this notice period, Mr. Hooke will continue to be employed by Macquarie Holdings (USA) Inc. and must not engage or prepare to engage in any business activity that is the same or similar to the business he was undertaking with his employer. Mr. Hooke is also entitled to severance under Macquarie’s severance plan discussed below.

Mr. Hooke’s employment agreement also provides that Mr. Hooke is subject to a confidentiality restrictive covenant for an unlimited duration. The employment agreement also provides that Mr. Hooke is subject to a non-solicitation restrictive covenant of employees and clients during his employment and for a six-month period thereafter. In addition, the employment agreement provides that Mr. Hooke is subject to a non-competition restrictive covenant during his employment and for a three-month period thereafter.

Under the terms of Mr. Weintraub’s employment agreement with Macquarie Holdings (USA) Inc., dated May 26, 2010, Mr. Weintraub will provide Macquarie Holdings (USA) Inc. two weeks’ notice if he voluntarily resigns and Macquarie Holdings (USA) Inc. will provide Mr. Weintraub two weeks’ notice of any termination for any reason other than for “cause,” as defined in the agreement. The period between such notice and termination of employment is referred to as the “notice period.” During the notice period, Mr. Weintraub will be entitled to continue to receive his salary and contributions to the group medical, dental, vision, life and disability plans. Upon termination, Mr. Weintraub will be entitled to payment of any accrued but unpaid vacation time. Macquarie may, in its discretion, alter Mr. Weintraub’s duties or place him on paid leave of absence during the notice period. In addition, Mr. Weintraub may not engage in any other business activity during his employment or the notice period. Mr. Weintraub is also entitled to severance under Macquarie’s severance plan discussed below.

The employment agreement provides that Mr. Weintraub is subject to a confidentiality restrictive covenant for an unlimited duration.

Macquarie’s Severance Plan

Under Macquarie’s severance plan applicable to U.S.-based staff including Mr. Hooke and Mr. Weintraub, if Mr. Hooke or Mr. Weintraub is terminated by Macquarie for reasons other than for cause or by voluntary resignation, he would be entitled to severance payments equal to four weeks’ base salary for the first year of employment plus three weeks’ base salary for each year thereafter, and pro rata payments for each complete month within any portion of a year.

33

Profit Share Arrangement

In the case of Mr. Hooke and Mr. Weintraub, unvested retention (pre-2009) may be paid on termination at the discretion of Macquarie where, for example, an employee’s employment ends of the grounds of genuine retirement, redundancy, death disability, illness or in other circumstances where business efficacy justifies exercising the discretion. In all other cases retention is forfeited on leaving Macquarie.

In the case of Mr. Hooke, amounts retained from 2009 onwards under the DPS Plan are fully vested and released where an executive director’s employment ends on the grounds of genuine retirement or redundancy or in certain other limited circumstances subject to the disqualifying events. The release will occur in accordance with the normal release schedule. Accordingly, if Mr. Hooke had been made redundant on December 31, 2011, he would be entitled to his account balance in the DPS Plan as reflected in the Nonqualified Deferred Compensation in Fiscal Year 2011 table, paid in accordance with the normal payment schedule.

Macquarie Group Employee Retained Equity Plan (“MEREP”)

The MEREP rules give Macquarie the discretion to fully vest the equity award on termination. The BRC or the Executive Committee under delegation from the board may consider exercising this discretion where, for example, a staff member dies, is totally and permanently disabled, gives notice of their intention to enter into genuine retirement or a staff member’s employment ends on the grounds of redundancy, illness or in other limited exceptional circumstances, such as hardship or where business efficacy justifies exercising the discretion. In all other cases, these equity awards are forfeited on leaving Macquarie.

Macquarie Group Employee Share Option Plan

Under the terms of the Macquarie Group Employee Share Option Plan, if an individual who has been granted options ceases to be an employee or consultant of Macquarie, their vested options lapse six months after they cease to be an employee or consultant and their unvested options lapse immediately. However, the Macquarie Executive Committee may, in its absolute discretion and on any conditions it thinks fit, determine that the options do not lapse at that time but lapse at the time and subject to the conditions it specifies, which may include that options that have not otherwise reached their vesting date are deemed to have vested, that the lapse date of any of the options is extended beyond six months after the date on which the individual ceased to be an employee or consultant or that any exercise conditions associated with the options are waived.

If Mr. Hooke or Mr. Weintraub dies, the Macquarie Executive Committee may, in its absolute discretion, and subject to any conditions that it specifies in relation to any exercise of its discretion in relation to the individual ceasing to be an employee or consultant, give approval for the relevant options to be transferred to the individual’s legal personal representatives.

If the Macquarie Executive Committee becomes aware of circumstances which, in its reasonable opinion, indicate that an individual has acted fraudulently, dishonestly or in a manner which is in breach of his or her obligations to Macquarie, it may, in its absolute discretion, determine that any or all of the options granted to the individual lapse immediately.

Payments Upon Resignation or Termination

If, as of December 31, 2011, Mr. Hooke or Mr. Weintraub’s employment had been terminated without cause, they would have been entitled to a severance payment of $105,769 and $129,688, respectively, under the Macquarie severance plan described above, in addition to accrued and unpaid vacation time. They may also receive unvested options and retained profit share amounts, subject to the discretions outlined above. Mr. Hooke and Mr. Weintraub would not be entitled to any severance in the event of death or disability. No amounts would have been payable in the event of their resignation or termination for cause, subject to discretions being exercised in relation to their options and retained profit share amounts.

AUDIT COMMITTEE REPORT

Our audit committee is composed of four independent directors, all of whom are financially literate. In addition, the board has determined that each of Mr. Brown, an independent director and the chairman of the audit committee, and Mr. Carmany, an independent director and the chairman of the nominating and corporate governance committee, qualify as audit committee financial experts as defined by the SEC. The audit committee operates under a written charter, which reflects NYSE listing standards and Sarbanes-Oxley Act requirements regarding audit committees. A copy of the charter is available on the Company’s website at www.macquarie.com/mic under “Investor Center/Governance.”

The audit committee’s primary role is to assist the board in fulfilling its responsibility for oversight of (1) the quality and integrity of the consolidated financial statements and related disclosures, (2) compliance with legal and regulatory requirements, (3) the independent auditors’ qualifications, independence and performance and (4) the performance of our internal audit and control functions.

Management is responsible for the preparation of the financial statements, the financial reporting process and the system of internal controls. The independent auditors are responsible for performing an audit of the financial statements in accordance with auditing standards generally accepted in the United States, and issuing an opinion as to the conformity of those audited financial statements to U.S. generally accepted accounting principles. The audit committee monitors and oversees these processes.

The audit committee has adopted a policy designed to ensure proper oversight of our independent auditor. Under the policy, the audit committee is directly responsible for the appointment, compensation, retention and oversight of the work of any registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing any other audit review (including resolution of disagreements among management, the Manager, and the auditor regarding financial reporting), or attestation services. In addition, the audit committee is responsible for pre-approving any non-audit services provided by the Company’s independent auditors. The audit committee’s charter also ensures that the independent auditor discusses with the audit committee important issues such as internal controls, critical accounting policies, any instances of fraud and the consistency and appropriateness of our accounting policies and practices.

The audit committee has reviewed and discussed with management and KPMG LLP, the independent auditor, the audited financial statements as of and for the year ended December 31, 2011. The audit committee has also discussed with KPMG LLP the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees). In addition, the audit committee has received from the independent auditor its written report required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed its independence from the Company and its management. The audit committee also considered whether the non-audit services provided by KPMG LLP to us during 2011 were compatible with its independence as auditor.

Based on these reviews and discussions, the audit committee has recommended to the board, and the board has approved, the inclusion of the audited financial statements in the Company’s annual report on Form 10-K for the year ended December 31, 2011.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

In this section, “we,” “us,” and “our” refer to the Company and its subsidiaries for all periods following the dissolution of the Trust and to the Company, the Trust and the Company’s subsidiaries prior to that time.

Related Party Transactions Policies

Our board recognizes that related party transactions present a heightened risk of conflicts of interest and therefore has adopted internal policies and protocols to be followed in connection with related party transactions.

The Company’s audit committee is required to approve any related party transactions, including those involving Macquarie Group entities and vehicles managed by the Macquarie Group, regardless of the dollar amount of the transaction. The protocol applies to all transactions involving the Company or any of its subsidiaries in which a Macquarie Group entity may receive a financial benefit.

In approving related persons transactions, the audit committee determines whether each related persons transaction referred to the committee is on arm’s-length terms or better. The audit committee is authorized to request and review any factual information to enable them to determine whether a related person transaction is on arm’s-length terms. This information may take the form of benchmarks comparing the terms of the proposed transaction to similar transactions involving unrelated parties or external fairness opinions.

Under the guidance of the audit committee, the Company’s chief executive officer and chief financial officer are responsible for managing any benchmarking or review process conducted in accordance with the protocol, in consultation with the Company’s general counsel. The Company’s general counsel is responsible for ensuring overall compliance with the protocol, including ensuring that related person transactions covered by the protocol are referred to the audit committee for approval, and for reporting such transactions at regular meetings of the Company’s board of directors. The Company’s risk and compliance manager is responsible for monitoring compliance with the protocol and educating all Company employees, including those seconded by our Manager, about the protocol.

Our board has also adopted a written policy pursuant to which it has pre-approved certain types of transactions with related parties assuming certain conditions are met. The pre-approval policy permits foreign exchange, interest rate hedge and other routine financial transactions (such as the establishment of bank, brokerage and custodial accounts) for which the terms provided by the related party are equal or more favorable to us than those quoted by unaffiliated counterparties. All pre-approved transactions are included as a standing item in reports to the Company’s board at regular meetings of the board.

Our Relationship With the Macquarie Group

Prior to our initial public offering, we were a member of the Macquarie Group of companies. Macquarie Infrastructure Management (USA) Inc., our Manager, is a part of the Macquarie Group. From time to time, we have entered into, and in the future we may enter into, transactions and relationships involving the Macquarie Group, including those with Macquarie Group Limited, its affiliates, or vehicles managed by the Macquarie Group. As discussed above, our audit committee is required to approve of any related person transactions, including those involving the Macquarie Group, except for those pre-approved by our board. Our chairman, alternate chairman and chief executive officer also serve as directors without compensation for affiliates of our Manager within the Macquarie Group.

Contractual Arrangements With Our Manager

Our Manager’s Investment in the Company and Registration Rights

Our Manager acquired 2,000,000 shares of trust stock concurrently with the closing of the initial public offering in December 2004, with an aggregate purchase price of $50.0 million, at a purchase price per share equal to the initial public offering price of $25.00, which were exchanged for LLC interests on June 25, 2007. Pursuant to the terms of the Management Agreement (discussed below), our Manager may sell these LLC interests at any time. Our Manager has also received additional shares of trust stock and LLC interests (the LLC interests replacing the trust stock following the dissolution of the Trust in June 2007) by reinvesting some performance fees and base management fees. At March 31, 2012 and December 31, 2011, our Manager held 4,524,332 LLC interests and 4,388,345 LLC interests, respectively, of our Company.

38

We entered into a registration rights agreement with our Manager under which we agreed to file a shelf registration statement under the Securities Act relating to the resale of all LLC interests owned by our Manager as soon as reasonably possible following December 21, 2005. In addition, our Manager may also require us to include its LLC interests in future registered offerings that we conduct, subject to cutback at the option of the underwriters of any such offering. On October 16, 2006, we filed a shelf registration statement on Form S-3 with the SEC, subsequently amended on June 25, 2007, which became automatically effective. The shelf registration statement covers resales by our Manager of any LLC interests registrable under the registration rights agreement. Concurrently with an equity offering in July 2007, our Manager sold 599,000 of its LLC interests at a price of $40.99 per LLC interest.

Since January 1, 2011, we had paid our Manager cash dividends on LLC interests held for the following periods:

Management Services Agreement

Management and Fees.  At the closing of our initial public offering, we entered into a management services agreement, or Management Agreement, pursuant to which our Manager manages the day-to-day operations and oversees the management teams of our operating businesses. In addition, our Manager has the right to appoint the chairman of our board and an alternate, subject to minimum equity ownership, and to assign, or second, to us, on a full-time basis, employees to assume the role of chief executive officer and chief financial officer and second or make other personnel available as required. Our Manager’s board appointees do not receive any compensation (other than out-of-pocket expenses) and do not have any special voting rights.

In accordance with the Management Agreement, our Manager is entitled to a quarterly base management fee based primarily on our Company’s market capitalization, and a performance fee, based on the performance of our Company’s stock relative to a U.S. utilities index. For the quarter ended March 31, 2012 and year ended December 31, 2011, our Manager did not earn a performance fee.

For the quarter ended March 31, 2012 and year ended December 31, 2011, we incurred base management fees of $5.0 million and $15.5 million, respectively. The unpaid portion of the fees at the end of each reporting period is included in due to manager-related party in the consolidated balance sheets. The following table shows our Manager’s election to reinvest its quarterly base management fees in additional LLC interests during 2011:

Period	Base Management Fee Amount ($ in thousands)		LLC Interests Issued (in shares)		Issue Date
Fourth quarter 2011	$	4,222		135,987		March 20, 2012
Third quarter 2011		3,465		130,344		November 30, 2011
Second quarter 2011		4,156		179,623		August 31, 2011
First quarter 2011		3,632		144,742		June 6, 2011

Our Manager is not entitled to any other compensation and all costs incurred by our Manager, including compensation of seconded staff, are paid by our Manager out of its base management fee. However, we are responsible for other direct costs including, but not limited to, expenses incurred in the administration or management of our businesses and investments, income taxes, audit and legal fees, acquisitions and dispositions and its compliance with applicable laws and regulations. During the quarter ended March 31, 2012 and year ended December 31, 2011, our Manager charged us $89,000 and $286,000, respectively, for reimbursement of out-of-pocket expenses. The unpaid portion of the out-of-pocket expenses at the end of the reporting period is included in due to manager-related party in our consolidated balance sheet.

39

Acquisition Opportunities.  Under the terms of the Management Agreement, our Manager has exclusive responsibility for reviewing and making recommendations to the board with respect to acquisition opportunities and dispositions. In the event that an opportunity is not originated by our Manager, our board must seek a recommendation from our Manager prior to making a decision concerning any acquisition or disposition. Our Manager and its affiliates refer to our board of directors any acquisition opportunities in accordance with the U.S. acquisition priorities below that are made available to the Macquarie Infrastructure and Real Assets division of the Macquarie Group unless our chief executive officer determines that such opportunity does not meet our acquisition criteria adopted by our board of directors.

We have first priority ahead of all current and future entities managed by our Manager or by members of the Macquarie Group within the Macquarie Infrastructure and Real Assets division in each of the following infrastructure acquisition opportunities that are within the United States:

• airport fixed base operations;

• airport parking;

• district energy; and

• “user pays”, contracted and regulated assets (as defined below) that represent an investment of greater than AUD $40.0 million ($41.5 million as of March 31, 2012).

“User pays” assets mean businesses that are transportation-related and derive a majority of their revenues from a per use fee or charge.

Contracted assets mean businesses that derive a majority of their revenues from long-term contracts with other businesses or governments.

Regulated assets mean businesses that are the sole or predominant providers of at least one essential service in their service areas and where the level of revenue earned or charges imposed are regulated by government entities.

We have first priority ahead of all current and future entities managed by our Manager or any Manager affiliate in all investment opportunities originated by a party other than our Manager or any Manager affiliate where such party offers the opportunity exclusively to us and not to any other entity managed by our Manager or any Manager affiliate within the Macquarie Infrastructure and Real Assets division.

Preferred Financial Advisor.  Affiliates of the Macquarie Group, including Macquarie Capital (USA) Inc., or MCUSA, have preferred provider status in respect of any financial advisory services to be contracted for by us. We will contract for such services on an arm’s-length basis on market terms upon approval by our audit committee. Any fees payable for such financial advisory services are in addition to fees paid under the Management Agreement.

Derivative Instruments and Hedging Activities

We have derivative instruments in place to fix the interest rate on certain outstanding variable-rate term loan facilities. MBL has provided interest rate swaps for The Gas Company. At March 31, 2012 and December 31, 2011, The Gas Company had $160.0 million of its term loans hedged, of which MBL was providing the interest rate swaps for a notional amount of $48.0 million. The remainder of the swaps are from an unrelated third party. During the quarter ended March 31, 2012 and year ended December 31, 2011, The Gas Company made net payments to MBL of $514,000 and $2.2 million, respectively, in relation to these swaps.

Other Transactions

Macquarie, through the Macquarie Insurance Facility (MIF), has an aggregated insurance buying program. By combining the insurance premiums of Macquarie owned and managed funds, MIF has been able to deliver very competitive terms to businesses that participate in the facility. MIF earns a commission from the insurers. In February 2012, we purchased our Directors and Officers liability insurance utilizing several of the MIF insurers. No payments were made to MIF by us during the quarter ended March 31, 2012 and the year ended December 31, 2011 for Directors and Officers liability insurance.

Atlantic Aviation, The Gas Company, and District Energy purchase and renew property and casualty insurance coverage on an ongoing basis from insurance underwriters who then pay commissions to MIF. For the quarter ended March 31, 2012 and for the year ended December 31, 2011, no payments were made directly to MIF for property and casualty insurance.

Atlantic Aviation entered into a copiers lease agreement with Macquarie Equipment Finance, or MEF, an indirect subsidiary of Macquarie Group Limited. For the quarter ended March 31, 2012 and year ended December 31, 2011, Atlantic Aviation incurred $6,000 and $23,000, respectively, in lease expense on these copiers. As of March 31, 2012 and December 31, 2011, Atlantic Aviation had prepaid the April 2012 and January 2012 monthly payment, respectively, to MEF for $2,000, which is included in prepaid expenses in the consolidated balance sheet.

No payments were made under these arrangements during the quarter ended March 31, 2012 and year ended December 31, 2011.

On August 29, 2008, Macquarie Global Opportunities Partners, or MGOP, a private equity fund managed by the Macquarie Group, completed the acquisition of the jet membership, retail charter and fuel management business units previously owned by Sentient Jet Holdings, LLC. The new company is called Sentient Flight Group (referred to hereafter as “Sentient”). Sentient was an existing customer of Atlantic Aviation. For the quarter ended March 31, 2012 and year ended December 31, 2011, Atlantic Aviation recorded $5.8 million and $20.5 million, respectively, in revenue from Sentient. As of March 31, 2012 and December 31, 2011, Atlantic Aviation had $359,000 and $452,000, respectively, in receivables from Sentient, which is included in accounts receivable in the consolidated balance sheets.

As a practical matter, we assist our Manager and our directors and officers by monitoring transactions and completing and filing Section 16 reports on their behalf.
