PROXY STATEMENT
FOR THE ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD AUGUST 22, 2012

July 9, 2012

This statement is furnished in connection with the solicitation on behalf of the Board of Directors of CommVault Systems, Inc. (which we refer to as we, us, our, CommVault or our company) of proxies to be voted at the Annual Meeting of Stockholders on August 22, 2012, or at any adjournment or postponement thereof. This proxy statement and the associated proxy card are first being made available at www.cfpproxy.com/6030, and we intend to begin distribution of the Notice Regarding the Availability of Proxy Materials to stockholders, on or about July 9, 2012. A copy of our annual report on form 10-K for the fiscal year ended March 31, 2012, which includes audited financial statements, is also being made available concurrently with the proxy statement at www.cfpproxy.com/6030.

Voting Rights and Solicitation

July 2, 2012 was the record date for the determination of stockholders entitled to vote at the Annual Meeting. On that date, 44,891,209 shares of common stock were outstanding and entitled to vote. Each stockholder is entitled to one vote for each share of common stock held of record. A list of stockholders entitled to vote at the Annual Meeting will be available for examination by stockholders during regular business hours at our principal executive offices located at 2 Crescent Place, Oceanport, New Jersey 07757 for 10 days preceding the meeting and also will be available for examination at the Annual Meeting.

Stockholders may provide voting instructions by completing, executing and returning the proxy card which we have provided. Alternatively, stockholders may submit a proxy over the Internet or by telephone in accordance with the instruction set forth on the proxy card or the Notice Regarding Availability of Proxy Materials. All properly completed, unrevoked proxies received prior to the close of voting at the Annual Meeting will be voted in accordance with the instructions provided. If a properly executed, unrevoked written proxy card submitted by a record holder does not specifically direct the voting of shares, the shares represented by such proxy will be voted (i) FOR the election of all nominees for election as director described in this proxy statement, (ii) FOR the ratification of the appointment of Ernst & Young LLP as our independent public accountants for the fiscal year ending March 31, 2013, (iii) FOR approval, on an advisory basis, of executive compensation, and (iv) in accordance with the judgment of the persons named in the proxy as to such other matters as may properly come before the Annual Meeting. If you are a beneficial owner of shares, the broker will ask you how you want your shares to be voted. If you give the broker instructions, the broker will vote your shares as you direct. If your broker does not receive instructions from you about how your shares are to be voted, one of two things can happen, depending on the type of proposal. Brokers who are members of the NYSE or Nasdaq have discretionary power to vote your shares with respect to “routine” matters, but they do not have discretionary power to vote your shares on “non-routine” matters. Brokers holding shares beneficially owned by their clients do not have the ability to cast votes with respect to the election of directors or executive compensation unless they have received instructions from the beneficial owner of the shares. It is therefore important that you provide instructions to your broker so that your vote with respect to directors and executive compensation is counted.

A proxy may be revoked at any time prior to the voting at the Annual Meeting by submitting a later-dated proxy (including a later-dated proxy via the Internet or telephone), giving timely written notice of such revocation to the Secretary of our company or by attending the Annual Meeting and voting in person.

The presence at the Annual Meeting, in person or by proxy, of holders of a majority of the issued and outstanding shares of common stock as of the record date is considered a quorum for the transaction of business. If you submit a properly completed proxy or if you appear at the Annual Meeting to vote in person, your shares of common stock will be considered part of the quorum. Directions to withhold authority to vote for any director, abstentions and broker non-votes (described below) will be counted to determine if a quorum for the transaction of business is present. Once a quorum is present, voting on specific proposals may proceed.

Assuming the presence of a quorum, the affirmative vote of (1) a plurality of the votes cast at the Annual Meeting (in person or by proxy) is required for the election of directors, and (2) holders of a majority of the common stock present at the Annual Meeting (in person or by proxy) and entitled to vote is required to ratify Ernst & Young LLP as our independent public accountants for the fiscal year ending March 31, 2013. As a non-binding, advisory vote, there is no specific approval requirement for the advisory vote on executive compensation proposal.

Effect of Abstentions and Broker Non-Votes

Because the election of directors is determined on the basis of a plurality of the votes cast, abstentions have no effect on the election of directors. Because the approval of a majority of shares present and entitled to vote is required to ratify the appointment of Ernst & Young LLP as our independent public accountants, abstentions have the effect of a vote against the proposal. Similarly, abstentions have the effect of a vote against the proposal to approve executive compensation (on an advisory basis).

If you hold shares through a broker or other nominee, your broker or nominee is permitted to exercise voting discretion only with respect to certain, routine matters. Broker non-votes are shares held by brokers or other nominees that do not have discretionary voting authority with respect to a matter and have not received specific voting instructions from the beneficial owner. Broker non-votes will be counted for purposes of establishing a quorum but will otherwise have no effect on the outcome of the vote on any of the matters presented for your vote.

Brokers who have not received voting instructions from beneficial owners may vote in their discretion with respect to Proposal No. 2 (the ratification of the appointment of our independent auditors).

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our Board of Directors is divided into three classes, with one class of directors elected for a three-year term at each annual meeting. Each Class consists of three directors. Each director holds office until the third annual meeting after the meeting at which such director is elected and until his or her successor is duly elected and qualified or until his or her earlier resignation, removal or death. The terms of the Class III Directors will expire at the 2012 Annual Meeting.

Upon the recommendation of the Nominations and Governance Committee, the Board of Directors has nominated N. Robert Hammer, Keith Geeslin and Gary B. Smith to hold office as Class III Directors until the annual meeting in 2015.

The persons named as proxy voters in the proxy card for our 2012 Annual Meeting, or their substitutes, will vote your proxy for all the nominees, each of whom has been designated as such by the Board of Directors, unless otherwise indicated in your proxy. CommVault has no reason to believe that the nominees named herein will be unavailable to serve as directors. However, in the event that any nominee for director withdraws or for any reason is not able to serve as a director, we will vote your proxy for the remainder of those nominated for director (except as otherwise indicated in your proxy) and for any replacement nominee designated by the Nominations and Governance Committee of the Board of Directors.

You may vote for or withhold your vote from any or all of the director nominees. Assuming a quorum is present, the affirmative vote of the plurality of votes cast at the Annual Meeting (in person or by proxy) will be required for the election of directors.

CORPORATE GOVERNANCE

· The Audit Committee operates under a written charter that governs its duties and responsibilities, including its sole authority to appoint or replace our independent auditors.

· The Audit Committee has adopted policies and procedures governing the pre-approval of all audit and non-audit services provided by our independent auditors.

The Board of Directors and Its Committees

General. Our Board of Directors currently comprises nine members, seven of whom are not officers of our company and two of whom are officers of our company. Our Board of Directors believes that our ratio of outside directors to inside directors represents a commitment to the independence of our Board of Directors and a focus on matters of importance to our stockholders.

Our Board of Directors has determined that Messrs. Frank J. Fanzilli, Jr., Armando Geday, Keith Geeslin, F. Robert Kurimsky, Daniel Pulver, Gary B. Smith and David F. Walker, all of the outside directors, are “independent” as that term is defined under the applicable listing standards of Nasdaq. In making this determination for each director, the Nominations and Governance Committee, on behalf of our Board of Directors, considered the standards of independence set forth in the Nasdaq Corporate Governance Listing Standards and all relevant facts and circumstances to ascertain whether there was any relationship between a director and our company that, in the opinion of the Nominating and Corporate Governance Committee, would interfere with the exercise of independent judgment in carrying out the responsibilities of the director, or any material relationship with our company (either directly, or as a partner, shareholder or other officer of an organization that has a relationship with our company).

During the year ended March 31, 2012, our Board of Directors held 6 meetings. All of our directors who served in the year ended March 31, 2012, attended more than 80% of the meetings of the Board of Directors and all meetings of the committees of the Board held and on which the director served. The Board of Directors is scheduled to meet in executive session, without management, at every Board meeting that the directors attend in person. Mr. Smith acts as lead independent director to chair these executive sessions and as primary spokesperson in communicating matters arising out of these sessions to our management.

Directors are encouraged to attend our annual meeting. Four of our directors attended our 2011 Annual Meeting. Because we do not schedule a Board of Directors meeting to coincide with our Annual Meeting, attendance at our Annual Meeting by our directors is encouraged but not required. The Board of Directors has three standing committees. These committees have the responsibilities and authority described later in this section.

Board Leadership Structure. CommVault’s policy regarding its leadership structure is to adopt the practice which best serves our company’s needs at any particular time. Our Board has currently determined that the most effective leadership structure for our company is for N. Robert Hammer to serve as both Chairman and Chief Executive Officer.

Mr. Hammer has consistently provided strong leadership to our company and Board since becoming Chairman and Chief Executive Officer in March 1998. His strategic vision and financial discipline have been integral to our company’s growth. Mr. Hammer’s dual role provides the opportunity for better decision making and Board leadership given the greater level of information provided through his access to both management and the Board. The dual role provides a high level of communication between management and the Board on all matters and capitalizes on Mr. Hammer’s successful history in leading both our company and the Board. The Board currently believes having on person serve as both Chief Executive Officer and Chairman of the Board also eliminates the potential of duplication of efforts and inconsistent actions, enabling the Board and management to work effectively toward the same goals and strategy.

While Mr. Hammer serves as Chairman, strong independent Board leadership is exerted by our lead independent director, Gary B. Smith, who provides additional support to the corporate governance structure. Under our Corporate Governance Policies, the lead independent director is responsible to coordinate the activities of the other independent directors and to fulfill other responsibilities established by the Board or the independent directors. Currently, our lead independent director’s specific responsibilities include presiding at executive sessions of the Board and facilitating communication between Board members and the Chairman. Our lead director also communicates to the CEO on issues identified by the other independent directors. As a member of the Nominations and Governance Committee, Mr. Smith participates in the annual Board performance evaluation process and in the assessment of our company’s Governance Policies. The lead independent director, and many of the other directors, communicates with the Chairman and Chief Executive Officer regarding appropriate agenda topics and other board related matters. In accordance with our Corporate Governance Policies, no director may serve as lead independent director for more than seven consecutive years.

Board Oversight of Risk. Our company’s policies and procedures relating to risk assessment and risk management are overseen by its Board of Directors. A fundamental part of risk assessment and risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for our company. The involvement of the Board in setting our company’s business strategy is a key part of its assessment of management’s risk tolerance and what constitutes an appropriate level of risk for our company. The Board of Directors considers risk management to varying degrees regularly at its meetings. The Board will adjust its practices with respect to risk oversight whenever it determines it needs to do so and will involve itself in particular areas or business circumstances where its proper exercise of oversight requires it.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk assessment and risk management. The Audit Committee is required under its charter to inquire of management and the independent auditor concerning significant financial risks or exposures and to assess the steps management has taken to minimize such risks. The Audit Committee also oversees our company’s internal audit function and reviews with the General Counsel any legal matters, including litigation, that may have a material impact on our company’s financial statements, financial condition or results of operations. In addition, the Compensation Committee assesses compensation related risk and the Nominations and Governance Committee addresses management and governance risk, including through its oversight of the succession planning process. Each of these Board committees reports to the full Board with respect to its risk oversight functions.

At the management level, our company has appointed our General Counsel as our Chief Compliance Officer to oversee risk related matters, and we have established a disclosure committee to monitor our company’s compliance with its disclosure obligations under law and Nasdaq regulations and an executive review committee to monitor and approve certain transactions or other corporate matters that deviate from our company’s standard practices. The senior management of our company, including the Chief Compliance Officer, report to the Board or Board committees regarding risk issues, including those identified by the foregoing committees. In accordance with our company’s Corporate Governance Policies, the Board has complete and open access to any member of our company’s management and any of our company’s employees, as well as any outside advisors or independent advisors retained by the Board. In addition, our company’s Chief Financial Officer and General Counsel and Chief Compliance Officer are available at Board and committee meetings to answer questions relating to risk oversight. Further, because the Chief Executive Officer and Chief Operating Officer are directors, they bring a unique perspective on our company’s risk profile and risk assessment to Board deliberations based on their day to day management responsibilities.

Audit Committee. The Audit Committee is responsible for the appointment of, compensation of and oversight over the work of our independent auditor. Additionally, the Audit Committee monitors the integrity of our financial statements, our independent auditor’s qualifications and independence, our compliance with legal and regulatory requirements and the performance of our internal audit function and independent auditor. The Audit Committee relies on the knowledge and expertise of our management, the internal auditors and the independent auditor in carrying out its oversight responsibilities. The members of the Audit Committee are Messrs. Walker (Chairman), Kurimsky and Pulver. The Audit Committee is comprised solely of directors who meet all of the independence standards for audit committee membership as set forth in the applicable listing standards of Nasdaq. The Board of Directors has determined that Mr. Walker qualifies as an “audit committee financial expert” as that term is defined in the SEC rules adopted pursuant to the Sarbanes-Oxley Act of 2002, and that each Audit Committee member has sufficient knowledge in financial and auditing matters to serve on the Audit Committee.

The Audit Committee operates under a written charter. The Audit Committee held 5 meetings in the year ended March 31, 2012. A report of the Audit Committee appears elsewhere in this proxy statement.

Compensation Committee. The Compensation Committee is responsible for overseeing our compensation and benefit plans, including all compensation arrangements for executive officers and directors. The members of the Compensation Committee are

Messrs. Geeslin (Chairman), Fanzilli and Geday. The Compensation Committee is comprised solely of outside directors who meet the independence standards for compensation and nominating committee members as set forth in Nasdaq listing standards.

Management assists the Compensation Committee in the performance of its duties. Each year, the Chief Executive Officer reviews the performance and compensation of each of the executive officers and makes recommendations to the Compensation Committee with respect to the executive officers’ compensation.

The Compensation Committee has the authority to engage its own independent advisors to assist in carrying out its responsibility. From time to time, consultants, including Radford, also provide additional services at the request of our company. In fiscal year 2012, the Compensation Committee and Management jointly engaged Radford (An Aon Hewitt Company) for services that included assistance and advice in the formulation of our company’s cash and equity compensation programs.

The Compensation Committee operates under a written charter. The Compensation Committee held 2 meetings and the Committee, or a sub-committee thereof, acted by unanimous written consent 17 times during fiscal year 2012. A report of the Compensation Committee appears elsewhere in this proxy statement. For a more detailed discussion of the Compensation Committee’s processes and procedures for considering and determining executive compensation, see “Executive Compensation — Compensation Discussion and Analysis.”

Nominations and Governance Committee. The Nominations and Governance Committee is responsible for identifying and recommending to our Board of Directors appropriate director nominee candidates and providing oversight with respect to corporate governance matters, including reviewing our corporate governance policy. The members of the Nominations and Governance Committee are Messrs. Pulver (Chairman), Kurimsky, Smith and Walker. The Nominations and Governance Committee is comprised solely of outside directors who meet the independence standards for compensation and nominating committee members as set forth in Nasdaq listing standards.

The Nominations and Governance Committee is responsible for assessing the appropriate balance of experience, skills and characteristics required of our Board of Directors and for carrying out adequate due diligence with respect to prospective board members. The Nominations and Governance Committee will consider nominees that are recommended by members of the Board of Directors, management or other stockholders. Nominees for director shall be selected on the basis of depth and breadth of experience, integrity, ability to make independent analytical inquiries, understanding of our business environment, the willingness of the candidate to devote adequate time to board duties, the interplay of the candidate’s experience and skills with those of other board members, and the extent to which the candidate would be a desirable addition to our Board of Directors and any committees of the Board.

If the Nominating and Corporate Governance Committee receives, prior to the date that is 120 days before the anniversary of the date of mailing for the prior year’s proxy statement, a nominee recommendation from a stockholder or group of stockholders that has beneficially owned more than 5% of our company’s voting common stock for at least one year as of the date of the recommendation, the name of the candidate, the name(s) of the stockholder(s) who recommended the candidate and whether the Nominating and Corporate Governance Committee chose to nominate the candidate will be disclosed in the proxy statement, if the consent of both the stockholder and the candidate has been received.

If a stockholder desires to nominate persons for election as director at any stockholders’ meeting duly called for the election of directors, written notice of the stockholder’s intent to make such a nomination must be given and received by the Secretary at our principal executive offices either by personal delivery or by United States mail not later than (i) with respect to an annual meeting of stockholders, 90 days prior to the anniversary date of the date on which notice of the prior year’s annual meeting was mailed to stockholders, and (ii) with respect to a special meeting of stockholders, the close of business on the tenth day following the date on which notice of such meeting is first sent or given to stockholders.

Each notice shall describe the nomination in sufficient detail for the nomination to be summarized on the agenda for the meeting and shall set forth:

· the name and address, as it appears on our books, of the stockholder who intends to make the nomination;

· a representation that the stockholder is a holder of record of our stock entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to present such nomination;

· whether the stockholder plans to deliver or solicit proxies from other stockholders;

· the class and number of our shares which are beneficially owned by the stockholder;

· the name and address of any person to be nominated;

· a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder;

· such other information regarding such nominee proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended; and

· the consent of each nominee to serve as a Director of our company if so elected.

The Nominations and Governance Committee operates under a written charter. The Nominations and Governance Committee met 3 times in the year ending March 31, 2012.

Stockholder Communication Policy. Stockholders can contact our Board of Directors to provide comments, to report concerns, or to ask a question, at the following address.

Corporate Secretary

CommVault Systems, Inc.

2 Crescent Place

Oceanport, New Jersey 07757

You may submit your concern anonymously or confidentially by postal mail.

Communications are distributed to our Board of Directors, or to any individual directors as appropriate, depending on the facts and circumstances outlined in the communication. You may also communicate online with our Board of Directors as a group through the Investor Relations section of our website at www.commvault.com. The Secretary will forward all communications to the Board to the Chairman of the Audit Committee or the Chairman of the Nominating and Governance Committee, who will determine when it is appropriate to distribute such communications to other members of the Board or to management.

Board Diversity. The Board of Directors has adopted a policy on Board diversity to be implemented by the Nominations and Governance Committee. This policy requires the Nominations and Governance Committee to consider diversity in professional experience, skills, broad-based business knowledge, understanding of our company’s business environment and training when recommending Director nominees to the Board, with the objective of achieving a board with diverse business and educational backgrounds. It is the goal of this policy for the Board to be composed of members with individual backgrounds that, when combined, provide a portfolio of experience and knowledge that will serve our company’s governance and strategic needs. In accordance with our company’s Corporate Governance Guidelines, the Nominations and Governance Committee will consider the interplay of the director candidate’s experience and skills with those of other Board members, as well as the extent to which the candidate would be a desirable addition to the Board and any Committees of the Board. When recommending nominees for Director, the Nominations and Governance Committee does not discriminate against candidates based on gender, ethnicity, religion or national origin. Our company’s Board diversity policy specifies that the Nominations and Governance Committee will review the skills and attributes of Board members within the context of the current make-up of the full Board from time to time as the Nominations and Governance Committee deems appropriate. In connection with its deliberations with respect to Director nominations for our company’s 2012 annual meeting, the Nominations and Governance Committee assessed that it effectively nominates candidates for Director in accordance with the above described standards, with the current Board being composed of individuals with finance, accounting, technology, management and international experience. See each nominee’s and director’s biography appearing earlier in this proxy statement for a description of the specific experiences that each such individual brings to the Board.

Transactions with Related Persons

The Board of Directors recognizes that transactions between us and certain related persons present a heightened risk of conflicts of interest. It is our policy to have the Audit Committee review and approve, ratify or disapprove of proposed transactions or courses of dealings with respect to which executive officers or directors or members of their immediate families have an interest (including all

transactions required to be disclosed pursuant to the SEC’s related persons disclosure requirements (“Related Persons Transactions”). The Audit Committee is to review such transaction based upon the rules of Nasdaq and upon the our ethics and governance guidelines. We did not enter into any Related Persons Transactions during the year ended March 31, 2012.

We have a Code of Business Ethics and Conduct, a copy of which is posted on the Investor Relations portion of our web page at www.commvault.com, which applies to all of our employees. The Code, among other things, has a policy governing conflicts of interests generally and, in particular, prohibiting employment or other activities in certain other businesses, soliciting clients for any other purpose or relationships that may be perceived as impairing the ability of the individual or our company from performing his or its duties, as the case may be, in an impartial manner, and use of corporate property for improper personal gain. Any complaints or concerns require disclosure to the Vice President, General Counsel or Vice President, Worldwide Human Resources and, if warranted, to the Audit Committee or Nominations and Governance Committee.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers and beneficial owners of 10 percent or more of a registered class of our equity securities to file with the SEC initial reports of beneficial ownership (Form 3) and reports on changes in beneficial ownership (Form 4 or 5). SEC rules adopted pursuant to Section 16(a) require that such persons furnish us with copies of all such forms they file with the SEC.

Based solely upon our review of such forms furnished to us during the year ended March 31, 2012, and upon the written representations received by us from certain of our directors and executive officers, we believe that our officers and 10% stockholders complied with all Section 16(a) filing requirements on a timely basis during the year ended March 31, 2012 except that due to an administrative error, Louis Miceli and Ron Miiller each had one late filing and each director had one late filing related to the receipt of their annual equity award.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

Management

Certain Other Stockholders

The following table sets forth, as of June 30, 2012, certain information regarding the persons known by us to be the beneficial owner of more than 5% of our outstanding common stock (the only class of voting securities outstanding).

(1) Based solely on a Schedule 13G/A filed on February 13, 2012 by BlackRock, Inc.

(2) Based solely on a Schedule 13G/A filing on February 14, 2012. Fidelity Management & Research Company (“Fidelity”), 82 Devonshire Street, Boston, Massachusetts 02109, a wholly-owned subsidiary of FMR LLC and an investment adviser registered under Section 203 of the Investment Advisers Act of 1940, is the beneficial owner of 2,464,596 shares or 5.5% of the Common Stock outstanding of the Company as a result of acting as investment adviser to various investment companies registered under Section 8 of the Investment Company Act of 1940.

Edward C. Johnson 3d and FMR LLC, through its control of Fidelity, and the funds each has sole power to dispose of the 2,464,596 shares owned by the Funds.

Members of the family of Edward C. Johnson 3d, Chairman of FMR LLC, are the predominant owners, directly or through trusts, of Series B voting common shares of FMR LLC, representing 49% of the voting power of FMR LLC. The Johnson family group and all other Series B shareholders have entered into a shareholders’ voting agreement under which all Series B voting common shares will be voted in accordance with the majority vote of Series B voting common shares. Accordingly, through their ownership of voting common shares and the execution of the shareholders’ voting agreement, members of the Johnson family may be deemed, under the investment Company Act of 1940, to form a controlling group with respect to FMR LLC.

Neither FMR LLC nor Edward C. Johnson 3d, Chairman of FMR LLC, has the sole power to vote or direct the voting of the shares owned directly by the Fidelity Funds, which power resides with the Funds’ Boards of Trustees. Fidelity carries out the voting of the shares under written guidelines established by the Funds’ Boards of Trustees.

Pyramis Global Advisors Trust Company (“PGATC”), 900 Salem Street, Smithfield, Rhode Island, 02917, an indirect wholly-owned subsidiary of FMR LLC and a bank as defined in Section 3(a)(6) of the Securities Exchange Act of 1934, is the beneficial owner of 8,200 shares or 0.02% of the outstanding Common Stock of the CommVault Systems, Inc. as a result of its serving as investment manager of institutional accounts owning such shares.

Edward C. Johnson 3d and FMR LLC, through its control of Pyramis Global Advisors Trust Company, each has sole dispositive power over 8,200 shares and sole power to vote or to direct the voting of 0 shares of Common Stock owned by the institutional accounts managed by PGATC as reported above.

FIL Limited (“FIL”), Pembroke Hall, 42 Crow Lane, Hamilton, Bermuda, and various foreign-based subsidiaries provide investment advisory and management services to a number of non-U.S. investment companies and certain institutional investors. FIL, which is a qualified institution under section 240.13d-1(b)(1)(ii), is the beneficial owner of 373,877 shares or 0.8% of the Common Stock outstanding of the Company.

Partnerships controlled predominantly by members of the family of Edward C. Johnson 3d, Chairman of FMR LLC and FIL, or trusts for their benefit, own shares of FIL voting stock. While the percentage of total voting power represented by these shares may fluctuate as a result of changes in the total number of shares of FIL voting stock outstanding from time to time, it normally represents more than 25% and less than 50% of the total votes which may be cast by all holders of FIL voting stock. FMR LLC and FIL are separate and independent corporate entities, and their Boards of Directors are generally composed of different individuals.

FMR LLC and FIL are of the view that they are not acting as a “group” for purposes of Section 13(d) under the Securities Exchange Act of 1934 (the “1934” Act) and that they are not otherwise required to attribute to each other the “beneficial ownership” of securities “beneficially owned” by the other corporation within the meaning of Rule 13d-3 promulgated under the 1934 Act. Therefore, they are of the view that the shares held by the other corporation need not be aggregated for purposes of Section 13(d). However, FMR LLC files a voluntary basis as if all of the shares are beneficially owned by FMR LLC and FIL on a joint basis.

(3) Based solely on a Schedule 13G filing on February 8, 2012. Vanguard Fiduciary Trust Company (“VFTC”), a wholly-owned subsidiary of The Vanguard Group, Inc., is the beneficial owner of 59,580 shares or 0.1% of the Common Stock outstanding of the Company as a result of its serving as investment manager of collective trust accounts. VFTC directs the voting of these shares.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Compensation Committee Membership and Organization

The Compensation Committee of the Board of Directors, or the Compensation Committee, has responsibility for establishing, implementing, and continually monitoring adherence with our company’s compensation philosophy. Its duties include:

· setting the total compensation of our Chief Executive Officer and evaluating his performance based on corporate goals and objectives;

· reviewing and approving the Chief Executive Officer’s decisions relevant to the total compensation of our company’s other executive officers;

· making recommendations to the Board of Directors with respect to equity-based plans in order to allow us to attract and retain qualified personnel; and

· reviewing director compensation levels and practices, and recommending, from time to time, changes in such compensation levels and practices to the Board of Directors.

The members of our Compensation Committee are Messrs. Fanzilli, Geeslin and Geday. Mr. Geeslin currently serves as Chairman of the Compensation Committee. Each member of the Compensation Committee is an “independent director” as such term is defined by Nasdaq’s Marketplace Rules. The Compensation Committee meets as necessary during the fiscal year as well as considers and takes action by written consent.

Executive Summary

We believe that the skill, talent, judgment and dedication of our executive officers are critical factors affecting the long-term value of CommVault. Therefore, the philosophy and objectives in setting compensation policies for executive officers are to align pay with performance, while at the same time providing fair, reasonable and competitive compensation that will allow us to retain and attract superior executive talent. The Compensation Committee strongly believes that executive compensation should align executives’ interests with those of shareholders by rewarding achievement of specific annual, long-term, and strategic goals by our company, with the ultimate objective of improving long-term stockholder value.

We believe our executive compensation program has been designed to pay for performance and is aligned with the long-term value of CommVault. For example, we believe the charts below demonstrate the strong correlation between our earnings and stock price growth and the compensation we paid to our President & CEO, Mr. Hammer, over the last five fiscal years.

The CEO compensation in the above tables is calculated on the same basis as in the fiscal 2012 Summary Compensation Table on page 26. The most significant component of Mr. Hammer’s compensation in the periods presented above is attributed to equity awards. The value of these equity awards are primarily related to the Black-Scholes fair value of stock options granted during the fiscal year. For example, for fiscal 2012 approximately 61% of Mr. Hammer’s total compensation is attributable to the black-scholes fair value of stock options granted during fiscal 2012 that vest over a 4 year period. All stock options granted to Mr. Hammer have an exercise price equal to the fair market value of CommVault stock. In order for Mr. Hammer to realize a future cash benefit for these stock options granted, CommVault’s stock price must continue to increase over time. In addition, approximately 19% of Mr. Hammer’s total compensation for fiscal 2012 is attributable to the fair value of restricted stock units that also vest over a 4 year period. In total, approximately 80% of Mr. Hammer’s total compensation for fiscal 2012 is equity based compensation.

1)	Non-GAAP EBIT (or non-GAAP income from operations) is defined as income from operations excluding noncash stock-based compensation charges and additional FICA and related payroll tax expense incurred by CommVault when employees exercise in the money stock options or vest in restricted stock awards. CommVault believes that non-GAAP EBIT is a useful metrics for management and investors because it compares CommVault’s core operating results over multiple periods. When evaluating the performance of CommVault’s operating results and developing short and long term plans, CommVault does not consider such expenses that are excluded in the computation of non-GAAP EBIT. See heading below labeled “Reconciliation of GAAP to Non-GAAP Financial Measures” for the detailed calculation of non-GAAP EBIT.
2)	Reflects non-equity cash incentive plan compensation. See heading below labeled “Non-Equity Incentive Plan Compensation” for more details.
3)	Reflects the aggregate grant price fair value of stock option and restricted stock unit awards computed in accordance with FAS ASC Topic 718.
4)	Reflects the stock price on the last business day of the fiscal year.

Mix of Compensation Elements. Our fiscal 2012 executive compensation program continued to consist of three principal elements: base salary, non-equity cash incentive awards and long-term equity-based incentive awards. The chart below illustrates the overall mix of compensation components for our named executive officers in total for fiscal 2012. Consistent with our pay for performance philosophy, the majority of our executive officers’ compensation in fiscal 2012 consisted of incentive awards, particularly long-term equity-based incentive awards. By using a significant equity-based element, we believe we create an incentive for our executive officers to achieve long-term stockholder value.

Fiscal 2012 Financial Highlights. We experienced strong year-over-year financial performance in fiscal 2012, including reporting record annual revenues $406.6 million, an increase of 29% over fiscal 2011. Our fiscal 2012 financial results were the basis of the non-equity cash incentive compensation paid to our executive officers. The following table illustrates our growth in fiscal 2012 in terms of total revenue, non-GAAP EBIT, non-GAAP diluted earnings per share, cash provided by operations and stock price.

	Fiscal 2012	Fiscal 2011	% Change 2011 to 2012

Revenue	$406.6 million	$314.8 million	29%
Non-GAAP income from Operations (EBIT)	$73.7 million	$52.9 million	39%
Non-GAAP Diluted Earnings per Share (EPS) (1)	$1.01	$0.76	33%
Cash Provided by Operations	$100.0 million	$52.4 million	91%
Stock Price (on last business day)	$49.64	$39.88	24%

1) Non-GAAP EPS is derived from non-GAAP net income divided by the weighted average shares outstanding on a fully diluted basis. Non-GAAP net income excludes noncash stock-based compensation and the additional FICA and related payroll tax expenses incurred by CommVault when employees exercise in the money stock options or vest in restricted stock awards as well as applies a non-GAAP effective tax rate of 36% in fiscal 2012 and 34% in fiscal 2011. CommVault believes that the use of a non-GAAP tax rate is a useful measure as it allows management and investors to compare its operating results on a more consistent basis over the multiple periods presented in its earnings release without the impact of significant variations in the tax rate. See heading below labeled “Reconciliation of GAAP to Non-GAAP Financial Measures” for the detailed calculation of Non-GAAP EPS.

Fiscal 2012 Executive Compensation. During fiscal 2012, we demonstrated our continued commitment to pay for performance and positive compensation practices in our executive compensation program. As described in further detail below, for the fiscal 2012 year:

· The base salaries for several of our executive officers increased by a somewhat larger percentage basis compared to prior years. However, these increases were primarily driven by market data as well as by strong Company and individual performance;

· We established aggressive performance goal targets and paid performance-based cash bonuses earned under our non-equity incentive plans for our executive officers that reflected the achievement of high levels of financial and operational performance as outlined in the above financial results table; and

· We granted stock option and restricted stock units under our long-term incentive plan that vest over a four year period. The value of these awards increased significantly over prior years primarily due our executive officers’ demonstrated ability to drive accelerating revenue, non-GAAP EBIT and cash flow growth in recent fiscal years. Equity awards granted to our executive officers are well aligned with shareholder interests, with a mix significantly weighted towards stock options instead of restricted stock units.

Compensation Philosophy and Objectives

As a growing high-technology company, we operate in an extremely competitive and rapidly changing industry. The Compensation Committee’s philosophy and objectives in setting compensation policies for executive officers are to align pay with performance, while at the same time providing fair, reasonable and competitive compensation that will allow us to retain and attract superior executive talent. The Compensation Committee strongly believes that executive compensation should align executives’ interests with those of shareholders by rewarding achievement of specific annual, long-term, and strategic goals of our company, with the ultimate objective of improving long-term stockholder value. The specific goals that our current executive compensation program rewards are focused primarily on revenue growth and profitability. To that end, the Compensation Committee believes executive compensation packages provided by our company to its executive officers should include a mix of both cash and equity-based compensation that reward performance as measured against established goals. As a result, the principal elements of our executive compensation are base salary, non-equity incentive plan compensation, long-term equity incentives generally in the form of stock options and/or restricted stock and post-termination severance and acceleration of equity award vesting for certain named executive officers upon termination and/or a change in control.

Our goal is to maintain an executive compensation program that will fairly compensate our executives, attract and retain qualified executives who are able to contribute to our long-term success, induce performance consistent with clearly defined corporate goals and align our executives’ long-term interests with those of our shareholders. The decision on the total compensation for our executive officers is based primarily upon an assessment of each individual’s performance and the potential to enhance long-term stockholder value. Often, judgment is relied upon and not upon rigid guidelines or formulas in determining the amount and mix of compensation for each executive officer. Factors affecting such judgment include performance compared to strategic goals established for the individual and our company at the beginning of the year, the nature and scope of the executive’s responsibilities, effectiveness in leading initiatives to achieve corporate goals, and conducting all activities in a manner consistent with our core company values.

Role of Executive Officers in Compensation Decisions

The Compensation Committee is responsible for setting the compensation of our Chief Executive Officer and also reviewing and approving our Chief Executive Officer’s decisions relevant to the compensation of our other executive officers. Our Chief Executive Officer, Chief Financial Officer and Vice President, Worldwide Human Resources support the Compensation Committee in its work by providing information relating to our financial plans, performance assessments of our executive officers and other personnel-related data. In addition, the Compensation Committee has authority under its charter to engage outside advisors and experts for advice as appropriate.

Peer Analysis of Executive Compensation

In the second quarter of fiscal 2012, the Company and our Compensation Committee jointly engaged Radford (An Aon Hewitt Company) to conduct a review and provide peer analysis information for structuring our base salary, non-equity incentive plan compensation programs and long-term equity incentive plan programs. The Compensation Committee and management used this data to ensure that our compensation programs are optimally structured to retain our highly experienced executive management team, to keep management focused during our expected period of growth, to motivate management to maximize stockholder value and to align our compensation practices with other comparable technology industry companies. Radford provided compensation data from 27 technology and related industry companies with annual revenues ranging from $132 million to $864 million and total headcount ranging from 569 to 9,015 employees. CommVault’s revenue for fiscal 2012 was approximately $407 million and its total headcount was 1,437 at March 31, 2012. The list of companies included in the survey were ACI Worldwide, Inc.; Actuate Corp.; Advent Software, Inc.; Athenahealth, Inc.; Blackbaud, Inc.; Blue Coat Systems, Inc.; Computer Programs and Systems, Inc.; CSG Systems International, Inc.; Digitial River, Inc.; Emulex Corp.; EPIQ Systems, Inc.; Informatica Corp; Jack Henry & Associates, Inc.; Limelight Networks; MicroStrategy, Inc.; Perficient, Inc.; Progress Software Corp.; QAD, Inc.; Qlik Technologies, Inc.; Quest Software, Inc.; Radiant Systems, Inc.; Riverbed Technology, Inc.; Sapient Corp.; SolarWinds, Inc.; Sourcefire, Inc.; SS&C Technologies Holdings. Inc.; and Websense, Inc.

Consideration of Prior Advisory Vote on Executive Compensation

Although the annual advisory stockholder vote on executive compensation is non-binding, the Compensation Committee has considered, and will continue to consider, the outcome of this vote each year when making compensation decisions for our named executive officers. At our 2011 Annual Meeting of Stockholders held on August 24, 2011, more than 97% of our stockholders who voted on the advisory executive compensation proposal approved the compensation of our named executive officers. The Compensation Committee believes that this substantial majority of votes casts affirms our stockholders’ support for our approach to executive compensation. Accordingly, the Compensation Committee did not make changes to our company’s compensation programs

expressly as a result of such vote. Reflecting our responsiveness to the preference expressed by our stockholders in 2011 with respect to the vote on frequency of the advisory vote on executive compensation, the Board of Directors has adopted a policy to submit the compensation of our named executive officers to stockholders for a non-binding advisory vote annually, at least until the company’s next Annual Meeting of Stockholders at which an advisory vote on the frequency of executive compensation votes is conducted.

Components of Executive Compensation

The principal components of compensation for our executive officers are:

· Base salary;

· Non-equity incentive plan compensation;

· Long-term equity incentives; and

· Other benefits

Base salary

We provide our executive officers and other employees with base salary to compensate them for services rendered during the fiscal year. We believe that our base salaries are competitive and we generally target our executive officer base salaries against the 50th — 75th percentile of the technology industry compensation data obtained. We target this range, allowing for compensation at the upper reaches where appropriate, because we have historically achieved revenue and earnings growth that is in the top tier of companies in our industry. In some circumstances, such as the need to retain key individuals, to recognize roles that were larger in scope or accountability than standard market positions and/or to reward individual performance, we may need to provide compensation above these ranges.

Salary levels are typically reviewed annually each October as part of our performance review process as well as upon a promotion or other change in job responsibility. In addition to considering the analysis provided by Radford discussed above, the Compensation Committee considered the scope of and accountability associated with each executive officer’s position; the performance of each executive officer since the last annual review in October 2010; and the overall experience of each executive officer when approving the base salary levels that became effective in October 2011. For fiscal 2012, the base salaries accounted for approximately 8% of total compensation for our Chief Executive Officer and 12% for our other named executive officers. The table below shows the fiscal 2011 and 2012 base salary rates for each named executive officers:

Name and Principal Position Held	Fiscal 2011 Salary (1)		Fiscal 2012 Salary (1)		Amount of Increase		Percentage Increase
N. Robert Hammer (2)	$	488,000	$	536,800	$	48,800	10.0%
Chairman, President and Chief Executive Officer

Alan G. Bunte (3)	380,000		418,000		38,000		10.0%
Executive Vice President and Chief Operating Officer

Louis F. Miceli (4)	316,000		330,200		14,200		4.5%
Senior Vice President and Chief Financial Officer

Ron Miiller (5)	277,000		310,000		33,000		11.9%

Senior Vice President of Marketing and Business Development

(1) Fiscal 2011 base salaries were effective in October 2010. Fiscal 2012 base salaries were effective in October 2011 for all of the named executives above except for Mr. Miiller. See Note 5 below for discussion on Mr. Miiller’s fiscal 2012 base salary increase.

(2) In fiscal 2012, Mr. Hammer’s base salary was increased by $48,800 to $536,800 to align his base salary at approximately to 50th percentile of the technology industry compensation data obtained.

(3) In fiscal 2012, Mr. Bunte’s base salary was increased by $38,000 to $418,000 to align his base salary at approximately the 75th percentile of the technology industry compensation data obtained.

(4) In fiscal 2012, Mr. Miceli’s base salary was increased by $14,200 to $330,200 which is slightly below the 50th percentile of the technology industry compensation data obtained.

(5) In April 2011, Mr. Miiller’s was promoted to Senior Vice President of Worldwide Sales. As a result, his base salary was increased by $33,000 to $310,000. Mr. Miiller’s base salary is at approximately the 50th percentile of the technology industry compensation data obtained.

(6) In fiscal 2012, Mr. West’s base salary was increased by $8,200 to $279,200 which is slightly above the 50th percentile of the technology industry compensation data obtained.

Non-Equity Incentive Plan Compensation

Non-equity incentive plan compensation for our executive officers is designed to reward performance against key corporate goals. In early fiscal 2012, the non-equity incentive plan compensation targets for that year were approved after considering targets for comparable positions provided by our external compensation consultant discussed above; the scope of and accountability associated with each executive officer’s position; and the performance and experience of each executive officer. The performance metrics against which our executive officers are measured are clearly communicated, consistently applied and are focused on corporate objectives. Our executive officer incentive targets are designed to motivate management to achieve specific goals related to certain revenue and profitability objectives. These metrics were selected because we believe that, at this stage of our development, they are most closely correlated to increasing stockholder value. We believe that our revenue and profitability goals are aggressive and not easy to achieve because they are based on growth objectives that we believe are higher than the industry average. Prior to fiscal 2012, only two times in the previous seven fiscal years had any of our named executive officers achieved a non-equity incentive plan award that was greater than 100% of their target. During fiscal 2012, our actual revenue and profitability growth rates resulted in non-equity incentive awards ranging from 115% to 145% of the targets set for our named executive officers.

Mr. Hammer — Fiscal 2012 Non-Equity Incentive Compensation

Our Chief Executive Officer, Mr. Hammer, is eligible for non-equity incentive plan compensation with a target bonus potential equal to 100% of his $536,800 base salary for fiscal 2012. Mr. Hammer’s target bonus is based on our company’s total revenue and non-GAAP income from operations (EBIT) achievement against the annual financial plan approved by our Board of Directors in which each performance measure is weighted equally. The Compensation Committee evaluates Mr. Hammer based on these performance metrics because we currently believe that growth in revenue and non-GAAP income from operations (EBIT) drives our ability to increase stockholder value. Non-GAAP income from operations (EBIT) excludes noncash stock-based compensation charges and additional FICA expense incurred when employees exercise in the money stock options or vest in restricted stock awards. We use non-GAAP income from operations (EBIT) internally to understand, manage and evaluate our business as well as to make operating decisions.

The terms of Mr. Hammer’s fiscal 2012 non-equity incentive plan contained both minimum threshold amounts that must be achieved to qualify for an award as well as additional payment amounts for surpassing the performance metrics. Specifically, actual results below 85% of revenue and non-GAAP income from operations result in no payment for the respective target.

Actual results at 85% of the revenue target result in a 25% payout for that component. For fiscal 2012, the total revenue achievement needed to obtain the minimum threshold payout of $67,100 on the revenue component was $312.8 million. For each additional $18.4 million, or 5%, that the revenue achievement is above $312.8 million, the resulting payout increases by approximately $67,100.

Actual results at 85% of non-GAAP income from operations (EBIT) result in a 65% payout for that component. The total non-GAAP income from operations (EBIT) achievement needed to obtain the minimum 65% threshold payout of $174,460 on the non-GAAP income from operations component (EBIT) was $54.7 million. Furthermore, actual results at 90% of non-GAAP income from operations (EBIT), or $57.9 million, result in a 75% payout for that component. For each additional $6.4 million, or 10%, that the

non-GAAP income from operations (EBIT) achievement is above $57.9 million, the resulting payout increases by approximately $67,100.

Actual revenue for fiscal 2012 was $406.6 million and actual non-GAAP income from operations was $73.7 million. As a result, Mr. Hammer was awarded $774,334, or approximately 144% of his fiscal 2012 target bonus amount, related to achievement against his total revenue and non-GAAP income from operations performance targets.

Mr. Bunte and Mr. Miceli — Fiscal 2012 Non-Equity Incentive Compensation

Our Chief Operating Officer, Alan Bunte, and our Chief Financial Officer, Louis Miceli, are also eligible for non-equity incentive plan compensation with a target bonus potential equal to a percentage of their base salaries. For fiscal 2012, Mr. Bunte’s target bonus was 95% of his $418,000 base salary and Mr. Miceli’s target bonus was 50% of his $330,200 base salary. Non-equity incentive plan compensation awarded to Messrs. Bunte and Miceli is determined and approved by Mr. Hammer and reviewed by the Compensation Committee. The performance goals for Messrs. Bunte and Miceli are both quantitative and qualitative. With respect to quantitative goals for fiscal 2012, Messrs. Bunte and Miceli were measured against the same performance objectives as Mr. Hammer. However, Mr. Hammer also considers achievement against qualitative objectives which are subjective in nature. Therefore, the ultimate non-equity incentive compensation achievement percentage awarded to Messrs. Bunte and Miceli may be either higher or lower than that of Mr. Hammer’s strictly quantitative calculation. Mr. Hammer does not use a specific formula or apply specific weights when evaluating performance and the resulting impact that such qualitative objectives have on the overall non-equity incentive compensation payout. Instead, Mr. Hammer uses his business judgment to determine an appropriate award after considering both the quantitative and qualitative objectives. Among the most important qualitative factors that Mr. Hammer uses to evaluate the performance of Messrs. Bunte and Miceli are: innovation; leadership; strategic planning; product development initiatives and achievements; financial and operational excellence; customer satisfaction; and staff development.

Mr. Hammer awarded Mr. Bunte a fiscal 2012 non-equity incentive award that was 144% of his target bonus amount resulting in a non-equity incentive plan compensation of $572,817, or 137%, of his base salary. Mr. Bunte’s award of 144% achievement against his target bonus amount was the same achievement percentage against target bonus amount that was earned by Mr. Hammer under his strictly quantitative non-equity incentive plan. In determining Mr. Bunte’s bonus award, Mr. Hammer considered the following achievements in addition to the financial performance of our company. During fiscal 2012, Mr. Bunte successfully led the release efforts related to enhancements for our existing Simpana 9 software suite. These enhancements included new capabilities that converge backup, archive and reporting processes; additional SnapProtect technology that deliver hardware snapshot integration; enhancements to virtual server protection; new innovations to protect data on laptops and desktops with embedded source deduplication for optimized efficiency; and new integration with Microsoft SharePoint. In addition, Mr. Bunte led our business and finance operation teams throughout fiscal 2012 in making critical resource and related investment decisions. Finally, during fiscal 2012, Mr. Bunte continued to enhance our best in class customer support organization. The results of our recent customer support survey raise the bar for excellence in delivering technical support and services that top industry averages for customer satisfaction, loyalty and retention.

Mr. Hammer awarded Mr. Miceli a fiscal 2012 non-equity incentive award that was 120% of his target bonus amount resulting in a non-equity incentive plan compensation of $198,120, or 60%, of his base salary. In determining Mr. Miceli’s bonus award, Mr. Hammer considered the following achievements in addition to the financial performance of our company. Mr. Miceli successfully led CommVault’s worldwide finance organization during fiscal 2012 and worked closely with Mr. Hammer and Mr. Bunte to lead company-wide efforts focused on resource and related investment decisions. In addition, during fiscal 2012 Mr. Miceli led several significant enhancements related to CommVault’s control environment and transactional processes as we automate and streamline all of our critical processes to scale with the anticipated growth of the company.

Mr. Miiller — Fiscal 2012 Non-Equity Incentive Compensation

Our Senior Vice President of Worldwide Sales, Ron Miiller, is eligible for non-equity incentive plan compensation with a target bonus potential equal to 100% of his $310,000 base salary for fiscal 2012. His fiscal 2012 non-equity incentive plan compensation is based on quarterly attainment related to worldwide commissionable software revenue; worldwide maintenance support revenue; and worldwide professional services revenue and annual attainment related to worldwide non-GAAP income from operations (EBIT). Commissionable software revenue generally consists of the dollar amount of software orders executed during the fiscal period for which software revenue has been recognized or will be recognized in the subsequent fiscal quarter. We believe compensating Mr. Miiller based on commissionable software revenue aligns his compensation with the employees within his the field organization whose compensation is directly influenced by our field sales employees’ efforts. The total combined amounts for worldwide maintenance support revenue and worldwide professional services revenue are reported in the services revenue line item contained in our consolidated statement of operations. Non-GAAP income from operations (EBIT) excludes noncash stock-based compensation

charges and additional FICA and related expenses incurred when employees exercise in the money stock options or vest in restricted stock awards. We use non-GAAP income from operations (EBIT) internally to understand, manage and evaluate our business as well as to make operating decisions.

Mr. Miiller’s non-equity incentive plan is most heavily weighted toward worldwide commissionable software revenue because he is primarily responsible for growing our worldwide software revenue. As a result, Mr. Miiller’s fiscal 2012 non-equity incentive plan was weighted 60% to worldwide commissionable software revenue; 25% to non-GAAP income from operations (EBIT); 10% to worldwide maintenance revenue; and 5% to worldwide professional services revenue. Mr. Miiller quarterly target pay-out for software revenue, maintenance support revenue and professional services revenue totals $58,125 per quarter (or $232,500 for the entire annual period) and his annual target pay-out for non-GAAP income from operations (EBIT) totals $77,500 for the entire fiscal year period.

The following table details the relationship between the percentage of commissionable software revenue, maintenance support revenue and professional services revenue targets achieved to the percentage of his $58,125 quarterly commission award earned.

	Target Achieved in Relation to Commission Award Earned
Percentage of target revenue achieved	85%	90%	95%	100%	105%	110%	115%	120%
Percentage of commission award earned	40%	65%	85%	100%	115%	130%	145%	160%

The maximum quarterly commission payout allowed under Mr. Miiller’s compensation plan is 120% of the applicable revenue target. No quarterly payment is made for less than 85% achievement of the individual target revenue amounts.

On an annual basis for fiscal 2012, the total annual commissionable software revenue achievement needed to obtain the annual minimum 40% threshold payout of $74,400 on the commissionable software revenue component was $156.4 million. The similar total for annual customer support revenue and professional services revenue, which we report as services revenue in our public filings, needed to obtain the combined 40% threshold payout of $18,600 was $164.9 million.

The following table details the relationship between the percentage of the non-GAAP income from operations (EBIT) target achieved to the percentage of his annual $77,500 commission award earned.

	Target Achieved in Relation to Commission Award Earned
Percentage of non-GAAP income from operations (EBIT) target achieved	85%	90%	100%	105%	110%	115%	120%
Percentage of commission award earned	65%	75%	100%	110%	120%	130%	140%

The maximum commission payout allowed under Mr. Miiller’s compensation plan is 120% of the applicable non-GAAP operating income (EBIT) target. No payment is made for less than 85% achievement of the non-GAAP income from operations (EBIT) target amount. On an annual basis for fiscal 2012, the total annual non-GAAP income from operations achievement needed to obtain the annual minimum 65% threshold payout of $50,375 on the non-GAAP income from operations component was $56.3 million.

Mr. Miiller’s non-equity incentive plan compensation also contains a quarterly consistency bonus calculation for his commissionable software revenue, maintenance support revenue and professional services revenue components. Under the quarterly consistency bonus calculation, for each quarterly performance that was at least 100% attainment and the preceding quarter(s) were also at least 100% attainment, the quarterly consistency achievement bonus will be awarded as follows:

Sequential Quarters At or		Consistency
Above 100% Attainment		Award Factor (1)
One		10%
Two		15%
Three		20%

(1) The consistency award factor is equal to the percentage in the above table multiplied by the quarterly non-equity incentive plan potential for the applicable compensation component.

Mr. Miiller was awarded $449,229, or 145% of his target commission award for fiscal 2012. This includes $26,157 paid to Mr. Miiller under the terms of his a quarterly consistency bonus.

We believe that the performance targets set for Mr. Miiller are challenging and require substantial effort in order to be attained which is evidenced by Mr. Miiller’s historical achievements against his performance targets of 79% in fiscal 2009, 102% in fiscal 2010, 88% in fiscal 2011 and 145% in fiscal 2012. Mr. Miiller’s performance targets for fiscal 2009, 2010 and 2011 were based on his responsibilities as Vice President Sales, Americas and his performance targets for fiscal 2012 are based on his responsibilities as Senior Vice President of Worldwide Sales. Mr. Miiller’s compensation plan includes quarter over quarter sequential growth targets that we believe are important to sustain consistent revenue growth over prior year actual amounts.

Mr. West — Fiscal 2012 Non-Equity Incentive Compensation

Our Senior Vice President of Marketing and Business Development, David West, was eligible for non-equity incentive plan compensation with a target bonus potential equal to 65% of his $279,200 ending base salary for fiscal 2012. Mr. West’s non-equity incentive compensation plan award for fiscal 2012 was calculated based on a percentage of worldwide software revenue; revenue specifically generated through our original equipment manufacturer (“OEM”) agreement with NetApp; funnel inflow; and marketing margin. Revenue specifically generated through OEM agreement with NetApp is related to our global OEM agreement with NetApp under which NetApp integrates elements of our Simpana 9 software suite with NetApp SnapShot™ and replication technology, under the NetApp SnapProtect® brand. Funnel inflow is defined as the net new forecasted software revenue opportunities being tracked by our sales and marketing teams on a worldwide basis during the fiscal year. Marketing margin is calculated as total software revenue less worldwide marketing expenses.

Mr. West’s non-equity incentive plan compensation is calculated and paid on a quarterly basis for software revenue and worldwide net funnel inflow and calculated and paid on an annual basis for NetApp OEM revenue and marketing margin. Mr. West’s non-equity incentive plan was most heavily weighted toward software revenue because he is primarily responsible for supporting our software revenue growth on a worldwide basis. As a result, Mr. West’s fiscal 2012 non-equity incentive plan was weighted 60% to worldwide software revenue; 15% to revenue specifically generated through our NetApp OEM agreement; 10% to worldwide funnel inflow; and 15% to marketing margin.

Under the terms of Mr. West’s fiscal 2012 non-equity incentive plan, no payment is made for less than 85% achievement of software revenue; less than 50% achievement for NetApp OEM revenue; less than 70% achievement of worldwide funnel inflow; and less than 85% achievement of marketing margin.

The following table details the relationship between the achievement percentage of each performance metric to the non-equity incentive plan award earned.

	Target Achieved in Relation to Award Earned
Software revenue
Percentage of target achieved	85%	90%	95%	100%	105%	110%	115%	120%
Percentage of award earned	40%	65%	85%	100%	115%	130%	145%	160%

NetApp Revenue Percentage of target achieved	50%	65%	80%	90%	95%	100%	105%	110%	120%	130%	140%	150%	160%	170%	180%
Percentage of award earned	25%	40%	55%	65%	85%	100%	110%	115%	130%	140%	150%	165%	175%	185%	200%

Worldwide Funnel Inflow
Percentage of target achieved	70%	85%	100%	105%	110%
Percentage of award earned	50%	70%	100%	105%	110%

Marketing Margin
Percentage of target achieved	85%	90%	100%	105%	110%	115%	120%
Percentage of award earned	65%	75%	100%	110%	120%	130%	140%

The maximum annual payout allowed under Mr. West’s non-equity incentive plan for software revenue is 160% of the target amount; for NetApp revenue is 200% of the target amount; for worldwide net funnel inflow is 110% of the target amount; and for marketing margin is 140% of the target amount.

On an annual basis for fiscal 2012, the total annual software revenue achievement needed to obtain the annual minimum 40% threshold payout on the software revenue component was $156.4 million.

Under the terms of his non-equity incentive plan, Mr. West achieved 104% of his targeted non-equity incentive compensation, or $188,600. In addition, Mr. Hammer awarded Mr. West an additional discretionary bonus of $20,000 to his non-equity incentive compensation. As a result, Mr. West was awarded in total $208,600, or 115% of his target non-equity incentive award for fiscal 2012.

For our executives with operational specific incentive targets such as NetApp OEM revenue, worldwide funnel inflow and marketing margin, we do not disclose the specific targets and related achievement against such targets. Our operational specific targets are highly confidential and are not reported publicly in a manner consistent with Mr. West’s non-equity incentive plan compensation. Disclosing specific operational targets would cause substantial harm to our competitive position as it would allow our competitors to reach conclusions related to geographic plans for growth, profitability, allocation of resources and changes in direction. We believe this would give competitors an unfair advantage and could result in a materially adverse impact on our stock price and negatively affect our stockholders. We believe that the performance targets set for Mr. West are challenging and require substantial effort in order to be attained which is evidenced by Mr. West’s historical consolidated achievement against such targets of 57% in fiscal 2009, 96% in fiscal 2010, 100% in fiscal 2011 and 115% for fiscal 2012. Mr. West’s non-equity incentive plan compensation includes sequential growth targets that we believe are important to sustain consistent revenue growth over prior year actual amounts.

In fiscal 2012, the Compensation Committee did not exercise discretion to increase or reduce the award amounts that resulted from the application of our non-equity incentive plan compensation. However, the committee has the authority to do so if it determines that an adjustment would serve our interests and the goals of our executive officer non-equity incentive plan compensation.

Long-Term Equity Incentive Awards

We currently provide long-term equity incentive compensation pursuant to our 2006 Long-Term Stock Incentive Plan (the “LTIP”). The LTIP permits the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock awards and stock unit awards based on, or related to, shares of our company’s common stock. As of March 31, 2012, we have only granted non-qualified stock options and restricted stock units under the LTIP to our executive officers. We anticipate that future grants under the LTIP will also include both non-qualified stock options and restricted stock units. Our stock options and restricted stock units generally vest over a four-year period and our stock options have a term of ten years. We believe that these provisions encourage a long-term perspective and encourage key employees to remain with our company.

We account for equity compensation paid to all of our employees under the rules of ASC 718 Compensation — Stock Compensation, which requires us to estimate and record compensation expense over the service period of the award. All equity awards to our employees, including executive officers, and to our directors have been granted and reflected in our consolidated financial statements, based upon the applicable accounting guidance, at fair market value on the grant date. Generally, the granting of a non-qualified stock option to our executive officers is not a taxable event to those employees, provided, however, that the exercise of such stock option would result in taxable income to the optionee equal to the difference between the fair market value of the stock on the exercise date and the exercise price paid for such stock. Similarly, a restricted stock award subject to a vesting requirement is also not taxable to our executive officers unless such individual makes an election under section 83(b) of the Internal Revenue Code of 1986, as amended. In the absence of a section 83(b) election, the value of the restricted stock award becomes taxable to the recipient as the restrictions lapse.

Generally, a significant stock option grant is made to a new executive officer around the time that executive officer commences employment. This grant is made within our guidelines for new-hire grants, consistent with the executive’s position. The guidelines were developed based on our historical practices and survey data. The size of each grant is set at a level that we believe is appropriate to create a meaningful opportunity for stock ownership based upon our company’s grant guidelines, the individual’s position with us and the individual’s potential for future responsibility and promotion. The relative weight given to each of these factors varies from individual to individual and all grants to executive officers are approved by the Compensation Committee.

Each executive officer’s performance during the prior year is measured as well as overall corporate performance when follow-on awards are granted and such performance is taken into account when determining equity awards. We generally grant follow-on equity awards on an annual basis. The terms of the award and the number of shares granted are established to ensure a meaningful incentive to remain an employee of our company. All equity awards under our LTIP are granted on the 10th business day of the calendar month in which the grant award is approved. There was one long-term equity incentive award granted to all of our executives during fiscal 2012. This grant occurred in October 2011 and was considered to be our fiscal 2012 long-term equity incentive award. Twenty-five

percent of these long-term equity awards vest in October 2012 and the remaining seventy-five percent vests in equal quarterly amounts thereafter through October 2015.

In anticipation of this equity award granted in October 2011, we utilized the technology industry compensation data described above in the “Peer Analysis of Executive Compensation” section to obtain comparable market data. The long-term equity incentive awards granted in October 2011 were generally targeted against 50th – 75th percentile of the technology industry compensation data obtained. This range was used because we believe that we have historically achieved revenue and earnings growth that is in the top tier of companies in our industry.

In determining the amount of the long-term equity incentive awards granted in October 2011, we reviewed the technology peer group data obtained primarily related to the shares awarded as a percentage of CommVault’s total common shares outstanding (“CSO”). The shares awarded in the CSO calculation utilize an option equivalency approach in which a 2:1 conversion ratio of stock options to full value shares or restricted stock is used. To use a balanced approach, we also reviewed the technology peer group data in terms of an estimated value (in dollars) of the potential award. Our Compensation Committee concluded that, with respect to the position of chief executive officer, the percentage of CSO should be approximately 0.6%.

Our Compensation Committee determined that the aggregate economic value of long-term equity incentive compensation awarded to the executive officers should contain a mix of non-qualified stock options and restricted stock units. Furthermore, long-term equity incentive awards granted to our executive officers are much more heavily weighted toward stock options because we believe that such awards align pay for performance by rewarding sustained achievement which drives long-term improvement of stockholder value. In addition, grants of restricted stock units allow us to offer equity compensation with fewer shares and less dilution to our stockholders, while simultaneously maintaining competitive rewards to retain our executive employee talent. As a result, the Compensation Committee allocated the value of Mr. Hammer’s long-term equity incentive award 75% to stock options and 25% to restricted stock units, which resulted in a grant of 218,750 stock options and 31,250 restricted stock units.

Using similar methodology, Messrs. Bunte, Miceli, Miiller and West were awarded each a long-term equity incentive award with an estimated percentage of CSO of approximately 0.4%, 0.2%, 0.2% and 0.1%, respectively. The estimated value of Mr. Bunte’s equity award granted in October 2011 was allocated 75% to stock options and 25% to restricted stock units. The estimated value of Messrs. Miceli, Miiller and West equity award granted in October 2011 was allocated 60% to stock options and 40% to restricted stock units. As a result, Mr. Bunte was granted 145,714 stock options and 24,286 restricted stock units; Mr. Miceli was granted 42,955 stock options and 14,318 restricted stock units; Mr. Miiller was granted 47,250 stock options and 15,750 restricted stock units; and Mr. West was granted 31,500 stock options and 10,500 restricted stock units.

In addition to the long-term equity incentive award granted to each of our executive officers in October 2011, Mr. Miiller also received a discretionary grant of an additional 12,000 stock options and 2,650 restricted stock units in April 2011. This award was granted in connection with his promotion to Senior Vice President of Worldwide Sales. This discretionary award vests over a four year period from April 2011 to April 2015.

We anticipate that we will continue to grant long-term equity incentive awards to each of our other executive officers on an annual basis at the discretion of the Compensation Committee. We have no program, plan or practice to coordinate award grants with the release of material non-public information. We anticipate that equity grants will generally occur in the third fiscal quarter. We believe that the resulting overlapping vesting schedule from awards made in prior years, together with the number of shares subject to each award, help provide meaningful retention incentives for executives and enhance stockholder value over time.

Other benefits

Our executive officer’s participate in benefit programs that are substantially the same as all other eligible employees of our company. These benefits include a matching contribution to our 401(k) plan starting January 1, 2012.

Stock Ownership Guidelines

We currently require our independent directors and our CEO to acquire an equity ownership interest in our common stock within five years of the date of our adoption of the policy (or five years from the date that they first became a director or CEO, as applicable) that, in the case of the independent directors is equal to five (5) times their base annual retainer, or in the case of our CEO is equal to five (5) times the CEO’s current annual base salary. The Compensation Committee is satisfied that this level of equity ownership

among our independent directors and our CEO, and the equity ownership interests of our other directors and executive officers, is sufficient to provide motivation and to align these group’s interests with those of our shareholders.

Financial Restatements

The Compensation Committee has not adopted a policy with respect to whether we will make retroactive adjustments to any cash- or equity-based incentive compensation paid to executive officers (or others) where the payment was predicated upon the achievement of financial results that were subsequently the subject of a restatement. Our compensation committee believes that this issue is best addressed when the need actually arises and all of the facts regarding the restatement are known.

Deductibility of Executive Compensation

As part of its role, the Compensation Committee reviews and considers the deductibility of executive compensation under Section 162(m) of the Code which precludes our company from taking a tax deduction for individual compensation in excess of $1 million for our CEO and our four other highest-paid officers. This section also provides for certain exemptions to this limitation, specifically compensation that is performance-based within the meaning of Section 162(m) of the Code.

(1)	Represents the total threshold amount with respect to each applicable metric under the fiscal 2012 non-equity incentive plans for each named executive officer. Actual total pay-outs may be less than the threshold amounts above if individual thresholds are not met. Mr. Hammer’s non-equity incentive compensation plan includes individual annual threshold amounts for total revenue and non-GAAP income from operations (EBIT). Mr. Miiller’s non-equity incentive compensation plan includes individual quarterly threshold amounts for worldwide commissionable software revenue; worldwide maintenance support revenue; and worldwide professional services revenue and annual attainment related to worldwide non-GAAP income from operations (EBIT). Mr. West’s non-equity incentive compensation plan includes individual threshold amounts for worldwide software revenue; revenue specifically generated through our original equipment manufacturer (“OEM”) agreement with NetApp; funnel inflow; and marketing margin. Annual non-equity incentive plans for Messrs. Bunte and Miceli do not contain threshold amounts. See “Non-Equity Incentive Plan Compensation” above for more information on the plans and performance objectives for each of our named executive officers.

(1)

Unless otherwise indicated, all stock option and restricted stock unit awards granted to named executive officers vest quarterly in equal installments over a four-year period, except that the shares that would otherwise vest quarterly over the first 12 months do not vest until the first anniversary of the grant. The vesting commencement date for all stock options and restricted stock units is the grant date.

(2)

Computed based on the number of unvested shares multiplied by the closing market price of our common stock at the end of fiscal year 2012. The actual value (if any) to be realized by the named executive officer depends on whether the shares vest and the future performance of our common stock. On March 31, 2012, the closing price of our common stock was $49.64 per share.

Option Exercises and Stock Vested

The following table sets forth information on the number and value of stock options exercised and restricted stock units vested during fiscal 2012 for the named executive officers.

	Option Awards		Stock Awards
Name	Number of Shares Acquired on Exercise	Value Realized on Exercise (1)	Number of Shares Acquired on Vesting	Value Realized on Vesting (2)
N. Robert Hammer	-	$ -	19,811	$	828,850
Alan G. Bunte	75,000	3,438,378	15,672	659,554
Louis F. Miceli	92,879	2,590,190	10,387	432,197
Ron Miiller	32,500	1,469,150	11,428	475,901
David R. West	110,000	4,467,191	10,085	425,083

(1)	The value realized on the exercise of stock options is based on the difference between the exercise price and the sale price of common stock at the time of exercise.
(2)	The value realized on the vesting of restricted stock units is based on the market price of our common stock on the day that the restricted stock vested.

Pension Benefits

None of our named executive officers participate in or have account balances in qualified or non-qualified defined benefit plans sponsored by us.

Nonqualified Deferred Compensation

None of our named executive officers participate in or have account balances in non-qualified defined contribution plans maintained by us.

Employment Agreements

In February 2004, we entered into an employment agreement with N. Robert Hammer. The agreement had an initial term ending on March 31, 2005 and automatically extends for additional one-year terms unless either party elects, at least 30 days prior to the expiration of a term, to terminate the agreement. The agreement provides that Mr. Hammer’s annual salary shall be subject to annual review by our Board of Directors. The agreement also provides that Mr. Hammer shall be eligible for annual non-equity incentive plan compensation with a target bonus potential equal to a percentage of his base salary and that he shall be entitled to participate in the employee benefits plans in which our other executives may participate. If we terminate Mr. Hammer’s employment for any reason other than cause, death or upon a change in control of our company, the agreement provides that, for a one-year period, Mr. Hammer will be entitled to receive his then-current base salary (either in equal bi-weekly payments or a lump sum payment, at our discretion) and we will be required to continue paying the premiums for Mr. Hammer’s and his dependents’ health insurance coverage. In addition, Mr. Hammer will be entitled to any other amounts or benefits previously accrued under our then applicable employee benefit plans, incentive plans or programs. If we terminate Mr. Hammer’s employment by reason of death or disability, Mr. Hammer will be entitled to any compensation earned but not yet paid. The agreement provides that, during his term of employment with us and for a period of one year following any termination of employment with us, Mr. Hammer may not participate, directly or indirectly, in any capacity whatsoever, within the United States, in a business in competition with us, other than beneficial ownership of up to one

percent of the outstanding stock of a publicly held company. In addition, Mr. Hammer may not solicit our employees or customers for a period of one year following any termination of his employment with us. Mr. Hammer’s employment agreement also contains a change in control provision which is discussed below in the section titled “Change in Control Agreements.”

Mr. Hammer has maintained his primary residence in the state of Florida since he began serving as our Chairman, President and Chief Executive Officer in 1998. Mr. Hammer’s position with us is his only full time employment. Mr. Hammer generally spends his time working for us in our office in Oceanport, New Jersey or traveling on business for us. He is generally in Oceanport when not traveling on business. As part of his annual compensation, we pay costs associated with Mr. Hammer’s travel between his residence in Florida and our headquarters in Oceanport, New Jersey and we also lease an apartment for Mr. Hammer’s use in New Jersey. See “Summary Compensation Table” for more information. The members of the Compensation Committee consider these costs in reviewing the annual compensation of Mr. Hammer. We do not believe that Mr. Hammer’s Florida residency has had a negative impact on the quality of his service to us or on his ability to meet his obligations as Chairman, President and Chief Executive Officer in the past and we do not anticipate that his Florida residency will have any negative impact on us in the future.

In February 2004, we entered into employment agreements with Alan G. Bunte and Louis F. Miceli. Each of these agreements had an initial term ending on March 31, 2005 and automatically extends for additional one-year terms unless either party to the agreement elects, at least 30 days prior to the expiration of a term, to terminate the agreement. The agreements with Messrs. Bunte and Miceli provide that the annual salary of each shall be subject to annual review by our chief executive officer or his designee, and also provides that each shall be eligible for annual non-equity incentive plan compensation with a target bonus potential equal to a percentage of the officer’s base salary. The agreements with Messrs. Bunte and Miceli each provide that these officers shall be entitled to participate in the employee benefits plans in which our other executives may participate. If we terminate the employment of either of these officers for any reason other than for cause or death, each of the agreements provide that, for a one-year period, the terminated officer will be entitled to receive his then-current base salary (either in equal bi-weekly payments or a lump sum payment, at our discretion) and we will be required to continue paying the premiums for the officer’s and his dependents’ health insurance coverage. In addition, the terminated officer will be entitled to any other amounts or benefits previously accrued under our then applicable employee benefit plans, incentive plans or programs. If we terminate Messrs. Bunte’s or Miceli’s employment by reason of death or disability, each executive officer will be entitled to any compensation earned but not yet paid. Each agreement provides that, during his term of employment with us and for a period of one year following any termination of employment with us, the officer may not participate, directly or indirectly, in any capacity whatsoever, within the United States, in a business in competition with us, other than beneficial ownership of up to one percent of the outstanding stock of a publicly held company. In addition, neither of these officers may solicit our employees or customers for a period of one year following any termination of employment with us.

Change in Control Agreements

Mr. Hammer’s employment agreement provides that if a change in control of our company occurs, all equity awards held by Mr. Hammer shall immediately become exercisable or vested. If a change in control of our company occurs and Mr. Hammer’s employment is terminated for reasons other than for cause (other than a termination resulting from a disability) within two years of the change in control, or if Mr. Hammer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment within two years following a change in control of our company, then he shall be entitled to (1) a lump sum severance payment equal to one and a half times his base salary at the time of the change in control plus an amount equal to Mr. Hammer’s target bonus at the time of the change in control, and (2) health insurance coverage for Mr. Hammer and his dependents for an 18 month period.

We have entered into change of control agreements with all of our executive officers, other than Mr. Hammer, whose employment agreement sets forth the protections upon a change of control described above. Each of these agreements provide that if a change in control of our company occurs and the employment of any of the officers is terminated for reasons other than for cause, or if the officer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment following a change in control of our company, then all equity awards held by the officer shall immediately become exercisable or vested. In addition, the change of control agreements with Messrs. Bunte and Miceli provide that if a change in control of our company occurs and the employment of either of these officers is terminated for reasons other than for cause within two years of the change in control, or if the officer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment within two years following a change in control of our company, then the officer shall be entitled to (1) a lump sum severance payment equal to one and a half times the sum of the officer’s annual base salary at the time of the change in control and all bonus payments made to the officer during the one-year period preceding the date of the change in control, and (2) health insurance coverage for the officer and his dependents for an 18 month period. The change of control agreements with Messrs. Miiller and West have substantially identical provisions that provide for a lump sum severance payment equal to the officer’s annual base salary at the time of the change in control and health insurance coverage for the officer and his dependents for a 12 month period.

The change of control agreements with Messrs. Bunte and Miceli provide that, for an 18 month period following the termination of employment, the officers may not engage in, or have any interest in, or manage or operate any company or other business (whether as a director, officer, employee, partner, equity holder, consultant or otherwise) that engages in any business which then competes with any of our businesses, other than beneficial ownership of up to five percent of the outstanding voting stock of a publicly traded company. The agreements also prohibit Messrs. Bunte and Miceli from inducing any of our employees to terminate their employment with us or to become employed by any of our competitors during the 18 month period. Messrs. Miiller and West are subject to substantially identical non-competition and non-solicitation provisions for a one-year period following the termination of employment.

Estimated Payments and Benefits upon Termination or Change in Control

The amount of compensation and benefits payable to each named executive officer has been estimated in the table below. The amounts below assume that such termination was effective as of March 31, 2012, the last day of our fiscal year. The actual amounts to be paid out can only be determined at the time of such executive’s separation from us.

(1)	Amounts in this column describe the value of stock options that would vest upon the triggering event described in the leftmost column. The value of stock options is based on the difference between the exercise price of the options and the $49.64 closing price of our common stock on March 31, 2012.

(2)	Amounts in this column describe the value of restricted stock units that would vest upon the triggering event described in the leftmost column, based on a closing price of $49.64 of our common stock on March 31, 2012.

None of the named executive officers are eligible for compensation and benefits payable upon involuntary termination for cause or voluntary resignation or retirement and therefore such descriptions have been excluded from the table above. In addition, the amounts shown in the table above do not include payments and benefits to the extent they are provided on a non-discriminatory basis to salaried employees generally upon termination, such as any unreimbursed business expenses payable and distributions of plan balances under the CommVault Systems, Inc. 401(k) plan.

Director Compensation

Our Compensation Committee of the Board of Directors determines the amount of any fees, whether payable in cash, shares of common stock or options to purchase common stock, and expense reimbursement that directors receive for attending meetings of the Board of Directors or committees of the Board of Directors.

During fiscal 2012, our Compensation Committee engaged a third party compensation consultant, Radford, to provide an assessment of our non-employee director compensation practices and also provided peer analysis information for structuring our director compensation practices related to cash compensation, equity compensation and equity vesting. The peer analysis was based on the same 27 technology and related industry companies described above in the Compensation Discussion and Analysis section heading “Peer Analysis of Executive Compensation”. Based on the results of the peer analysis date provided, we believe that CommVault’s director annual cash compensation is between the 50th and 75th percentile of the peer compensation data received and our director annual equity compensation exceeds the 75th percentile of the peer compensation data received. Our annual equity compensation exceeds the 75th percentile of the peer compensation data received primarily due to the annual cliff vesting of equity grants as more fully described below.

The fiscal 2012 cash compensation earned by non-employee directors for their services as members of the Board of Directors or any committee of the Board of Directors was as follows:

·	Annual retainer of $42,000 with an additional $2,000 for each board meeting attended;

·	The chairperson of our Audit Committee, Compensation Committee and Governance Committee receive an additional annual retainer of $30,000, $15,000 and $12,000, respectively;

·	The lead director receives an additional annual retainer of $20,000; and

·	Each committee member of the Audit Committee, Compensation Committee and Governance Committee receives an additional annual retainer of $15,000, $10,000 and $5,000, respectively.

Non-employee directors are also eligible to receive equity compensation under our LTIP in which that all equity awards granted to non-employee directors will generally cliff vest, with the entire award vesting one year from the date of grant. In fiscal 2012, we made an equity grant to our non-employee directors in October 2011 related to our fiscal 2012 LTIP award. This equity grant included 7,500 non-qualified stock options and 4,000 restricted stock units to each non-employee director in which the entire award will cliff vest in October 2012. All future equity grants to our non-employee directors will be pursuant to our LTIP. See “Long-Term Equity Incentive Awards” above for more information about this plan. We also reimburse all of our directors for their reasonable expenses incurred in attending meetings of our board or committees.

The following table sets forth information concerning the compensation received for services rendered to us by our directors in fiscal 2012:

Name	Fees Earned or Paid in Cash		Stock Awards (1)		Option Awards (1)		Total

Compensation Policies and Practices as They Relate to Risk Management

We have reviewed our compensation policies and practices for all employees and concluded that any risks arising from our policies and practices are not reasonably likely to have a material adverse effect on us.

Employee Benefit Plans

1996 Stock Option Plan

We have reserved 11,705,000 shares of common stock for issuance under the 1996 Stock Option Plan. As of March 31, 2012, options to purchase 1,932,716 shares of common stock were outstanding at a weighted average exercise price of $5.44 per share, 9,209,935 shares had been issued upon the exercise of outstanding options and 562,348 shares remain available for future grants. The 1996 Stock Option Plan provides for the grant of nonqualified stock options and other types of awards to our directors, officers, employees and consultants, and is administered by our Compensation Committee.

The Compensation Committee determines the terms of options granted under the 1996 Stock Option Plan, including the number of shares subject to the grant, exercise price, term and exercisability, and has the authority to interpret the plan and the terms of the awards thereunder. The exercise price of stock options granted under the plan must be no less than the par value of our common stock, and payment of the exercise price may be made by cash or other consideration as determined by the Compensation Committee. Options granted under the plan may not have a term exceeding ten years, and generally vest over a four-year period. At any time after the grant of an option, the Compensation Committee may, in its sole discretion, accelerate the period during which the option vests.

Generally, no option may be transferred by its holder other than by will or the laws of descent and distribution or pursuant to a qualified domestic relations order as defined by the Internal Revenue Code or Title I of the Employment Retirement Income Security Act of 1974, as amended, or the rules thereunder. If an employee leaves our company or is terminated, then any options held by such employee generally may be terminated, and any unexercised portion of the employee’s options, whether or not vested, may be forfeited.

The number of shares of common stock authorized for issuance under the 1996 Stock Option Plan will be adjusted in the event of any dividend or other distribution, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition or all or substantially all of the assets of our company, or exchange of common stock or other securities of our company, issuance of warrants or other rights to purchase common stock of our company, or other similar corporate transaction or event. In the event of the occurrence of any of these transactions or events, our Compensation Committee may adjust the number and kind of authorized shares of common stock under the plan, the number and kind of shares of common stock subject to outstanding options and the exercise price with respect to any option. Additionally, if any of these transactions or events occurs or any change in applicable laws, regulations or accounting principles is enacted, the Compensation Committee may purchase options from holders thereof or prohibit holders from exercising options. The Compensation Committee may also provide that, upon the occurrence of any of these events, options will be assumed by the successor or survivor corporation or be substituted by similar options, rights or awards covering the stock of the successor or survivor corporation.

The 1996 Stock Option Plan may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by our Board of Directors or our Compensation Committee. However, no action of our Compensation Committee or our Board of Directors that would require stockholder approval will be effective unless stockholder approval is obtained. No amendment, suspension or termination of the plan will, without the consent of the holder of options, alter or impair any rights or obligations under any options previously granted, unless the underlying option agreement expressly so provides. No options may be granted under the plan during any period of suspension or after its termination.

2006 Long-Term Stock Incentive Plan

On January 26, 2006, the Board of Directors authorized the creation of the Long-Term Stock Incentive Plan (the “LTIP”). Upon the close of our initial public offering on September 26, 2006, we became eligible to grant awards under the LTIP. Under the LTIP, we may grant stock options, stock appreciation rights, shares of common stock and performance units to our employees, consultants, directors and others persons providing services to our company.

The maximum number of shares of our common stock that was initially allowed to be awarded under the LTIP was 4,000,000. On each April 1, the number of shares available for issuance under the LTIP is increased, if applicable, such that the total number of shares available for awards under the LTIP as of any April 1 is equal to 5% of the number of outstanding shares of our common stock on that April 1. As of March 31, 2012, there were 4,723,270 options to purchase shares of common stock outstanding at a weighted average exercise price of $24.82 per share and there were 1,113,398 shares of non-vested restricted stock awards outstanding. In addition, as of March 31, 2012, there were approximately 515,833 shares that remain available for future grants under the LTIP. The maximum number of shares that may be subject to incentive stock options shall be 25,000,000 over the life of the LTIP. The maximum number of shares that may be subject to options and stock appreciation rights granted to any one individual shall be 25,000,000 over the life of the LTIP. The maximum number of shares that may be subject to stock unit awards, performance share awards, restricted stock awards or restricted unit awards to any one individual that are intended to be performance based within the meaning of Section 162(m) of the Internal Revenue Code shall be 25,000,000 over the life of the LTIP (or $1,000,000 during any calendar year, if settled in cash.) The number of shares of common stock authorized for issuance under the LTIP will be adjusted in the event of any dividend or other distribution, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition or all or substantially all of the assets of our company, or exchange of common stock or other securities of our company, issuance of warrants or other rights to purchase common stock of our company, or other similar corporate transaction or event.

Our Compensation Committee administers our LTIP. The LTIP essentially gives the Compensation Committee sole discretion and authority to select those persons to whom awards will be made, to designate the number of shares covered by each award, to establish vesting schedules and terms of each award, to specify all other terms of awards and to interpret the LTIP.

Options awarded under the LTIP may be either incentive stock options or nonqualified stock options, but incentive stock options may only be awarded to our employees. Incentive stock options are intended to satisfy the requirements of Section 422 of the Internal Revenue Code. Nonqualified stock options are not intended to satisfy Section 422 of the Internal Revenue Code. Stock appreciation rights may be granted in connection with options or as free-standing awards. Exercise of an option will result in the corresponding surrender of the attached stock appreciation right. The exercise price of an option or stock appreciation right must be at least equal to the par value of a share of common stock on the date of grant, and the exercise price of an incentive stock option must be at least equal to the fair market value of a share of common stock on the date of grant. Options and stock appreciation rights will be exercisable in accordance with the terms set by the Compensation Committee when granted and will expire on the date determined by the Compensation Committee, but in no event later than the tenth anniversary of the grant date. If a stock appreciation right is issued in connection with an option, the stock appreciation right will expire when the related option expires. Special rules and limitations apply to stock options which are intended to be incentive stock options.

Under the LTIP, our Compensation Committee may grant common stock to participants. In the discretion of the committee, stock issued pursuant to the LTIP may be subject to vesting or other restrictions. Participants may receive dividends relating to their shares issued pursuant to the LTIP, both before and after the common stock subject to an award is earned or vested.

The Compensation Committee may award participants stock units which entitle the participant to receive value, either in stock or in cash, as specified by the Compensation Committee, for the units at the end of a specified period, based on the satisfaction of certain other terms and conditions or at a future date, all to the extent provided under the award. A participant may be granted the right to receive dividend equivalents with respect to an award of stock units by the Compensation Committee. Our Compensation Committee

establishes the number of units, the form and timing of settlement, the performance criteria or other vesting terms and other terms and conditions of the award at the time the award is made.

Unless our Compensation Committee determines otherwise, in the event of a change in control of our company that is a merger or consolidation where our company is the surviving corporation (other than a merger or consolidation where a majority of the outstanding shares of our stock are converted into securities of another entity or are exchanged for other consideration), all option awards under the LTIP will continue in effect and pertain and apply to the securities which a holder of the number of shares of our stock then subject to the option would have been entitled to receive. In the event of a change of control of our company where we dissolve or liquidate, or a merger or consolidation where we are not the surviving corporation or where a majority of the outstanding shares of our stock is converted into securities of another entity or are exchanged for other consideration, all option awards under the LTIP will terminate, and we will either (1) arrange for any corporation succeeding to our business or assets to issue participants replacement awards on such corporation’s stock, or (2) make any outstanding options granted under the plan fully exercisable at least 20 days before the change of control becomes effective.

AUDIT COMMITTEE REPORT

General

The Audit Committee comprises three directors and operates under a written charter for the Audit Committee. All of the members of the Audit Committee meet the definition of independent for purposes of the Nasdaq listing standards. In addition, our Board of Directors has determined that Mr. Walker qualifies as an “audit committee financial expert” under the applicable SEC rules and all of the members of Audit Committee satisfy Nasdaq’s financial literacy requirements.

Report

The Audit Committee has furnished the following report:

The Audit Committee has reviewed and discussed the audited financial statements of our company for the fiscal year ended March 31, 2012 with our management. In addition, the Audit Committee has discussed with Ernst & Young LLP, our independent auditors (“Ernst & Young”), the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AU Section 380) as adopted by the PCAOB, “Communications with Audit Committees” and PCAOB Auditing Standard No. 2, “An Audit of Internal Control Over Financial Reporting Performed in Conjunction with an Audit of Financial Statements.”

The Audit Committee has also received the written disclosures and the letter from Ernst & Young required by PCAOB Ethics and Independence Rule 3526, “Communication with Audit Committees Concerning Independence,” and has discussed with Ernst & Young its independence from our company and our management.

The Audit Committee has considered whether the services rendered by our independent public accountants with respect to audit, audit-related, tax and other non-audit fees are compatible with maintaining their independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements for our company for the fiscal year ended March 31, 2012 be included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2012 for filing with the SEC.

PROPOSAL NO. 2

RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITORS

Financial statements of our company and our consolidated subsidiaries will be included in our Annual Report furnished to all stockholders. The Audit Committee of the Board of Directors has appointed Ernst & Young LLP as independent public accountants for us to examine our consolidated financial statements for the fiscal year ending March 31, 2013, and has determined that it would be desirable to request that the stockholders ratify the appointment. You may vote for, vote against or abstain from voting with respect to this proposal. Assuming the presence of a quorum, the affirmative vote of a majority of the shares present, in person or by proxy, at the Annual Meeting and entitled to vote is required to ratify the appointment. If the stockholders do not ratify the appointment, the Audit Committee will reconsider the appointment for the 2014 fiscal year, rather than the 2013 fiscal year, because of the difficulty and expense involved in changing independent auditors on short notice. Ernst & Young LLP was engaged as our principal independent public accountants for fiscal years 1998 through 2012. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting and are also expected to be available to respond to appropriate questions.

Audit, Audit-Related, Tax and All Other Fees

The following table summarizes the aggregate fees and expenses billed to us for the fiscal years ended March 31, 2012 and 2011 by our principal accounting firm, Ernst & Young LLP (“Ernst & Young”):

	2012		2011
	(In thousands)
Audit fees	$	1,239	$	1,259
Audit-related fees	8		21
Tax fees	478		565
All other fees	—		—
	$	1,725	$	1,845

Audit Fees — all services necessary to perform an audit of the consolidated financial statements of our company; the reviews of our company’s quarterly reports on Form 10-Q; services in connection with statutory and regulatory filings or engagements; comfort letters; statutory audits; consents and review of documents filed with the SEC.

Audit Related Fees — consultation concerning financial accounting and reporting standards.

Tax Fees — tax compliance; tax planning; and other tax advice.

All Other Fees — any other work that is not Audit, Audit-Related or a Tax Service.

In considering the nature of the services provided by Ernst & Young, the Audit Committee determined that such services are compatible with the provision of independent audit services. The Audit Committee discussed these services with Ernst & Young and our management to determine that they are permitted under the rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as by the American Institute of Certified Public Accountants.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Auditor

The audit committee is responsible for appointing, setting compensation and overseeing the work of the independent auditor. The Audit Committee has established a policy regarding pre-approval of permissible non-audit services provided by the independent auditor. Generally, pre-approvals may be made by the chairperson of the Audit Committee in accordance with the rules of the Securities and Exchange Commission. All of the services performed by Ernst & Young in the year ended March 31, 2012 were pre-approved in accordance with the pre-approval policy adopted by the Audit Committee.

The Board of Directors recommends that you vote FOR this proposal.

PROPOSAL NO. 3

ADVISORY VOTE ON EXECUTIVE COMPENSATION

The recently enacted Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our stockholders to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers whose compensation is reported in the compensation tables that appear earlier in this proxy statement as such compensation is 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 heading “Executive Compensation—Compensation Discussion and Analysis,” we strive to enhance long-term stockholder value by closely aligning our executive compensation philosophy and practices with the interests of our stockholders by rewarding achievement of specific annual, long-term, and strategic goals by our company, focusing on revenue growth and profitability. Our executive compensation program is designed to attract, motivate, and retain talented executives who possess the skills required to formulate and drive our company’s strategic direction and achieve annual and long-term performance goals necessary to create stockholder value. Our compensation practices, which balance long-term and short-term awards, are structured to pay for performance, to encourage business decision-making aligned with the long-term interests of our company and to promote and to support the human resource requirements of our business. Please read the “Compensation Discussion and Analysis” discussion for additional details about our executive compensation programs, including information about the fiscal year 2012 compensation of our named executive officers.

We believe that our executive compensation programs are structured in the best manner possible to support our company and our business objectives. We are asking our stockholders to indicate their support for our named executive officer compensation as described on pages 14 – 35 of this proxy statement, which include 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 stockholders 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 and the philosophy, policies and practices described in this proxy statement. Accordingly, we will ask our stockholders to vote FOR the following resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to the Commvault’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and any related material disclosed in the Commvault’s proxy statement is hereby APPROVED.”

The say-on-pay vote is advisory, and therefore not binding on our company, the Compensation Committee or the Board of Directors. However, the Board of Directors and the Compensation Committee value the opinions of our stockholders and will review the voting results. To the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, we will consider our stockholders’ concerns and the Compensation Committee would evaluate whether any actions are necessary to address those concerns.

Because Proposal No. 3 is a non-binding, advisory vote, there is no specific approval requirement. However, the Board of Directors will consider that the stockholders have approved executive compensation on an advisory basis if this proposal receives the affirmative vote of a majority of the votes present (in person or by proxy) and entitled to vote on this proposal.

The Board of Directors recommends that you vote FOR the approval of executive compensation.

OTHER MATTERS

The Board of Directors is not aware of any other matters that may properly come before the Annual Meeting. However, should any such matters come before the Annual Meeting, it is the intention of the persons named in the enclosed form of proxy card to vote all proxies (unless otherwise directed by stockholders) in accordance with their judgment on such matters.

INCORPORATION BY REFERENCE

To the extent that this proxy statement is incorporated by reference in any other filing by us under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, the information included or incorporated in the sections of this proxy statement entitled “Executive Compensation — CommVault Systems, Inc. Compensation Committee Report on Executive Compensation” and “Report of Audit Committee” will not be deemed to be incorporated, unless specifically provided otherwise in such filing.

SOLICITATION AND EXPENSES OF SOLICITATION

The cost of solicitation of Proxies will be borne by us. Solicitation will be made by mail, and may be made by directors, officers, and employees, personally or by telephone, telecopy or telegram. Proxy cards and material also will be distributed to beneficial owners of stock through brokers, custodians, nominees and other like parties, and we expect to reimburse such parties for their charges and expenses.

SUBMISSION OF STOCKHOLDER PROPOSALS

Stockholder Proposals — Inclusion in Company Proxy Statement

For a stockholder proposal to be considered by us for inclusion in our proxy statement and form of proxy relating to the annual meeting of stockholders to be held in 2013, the proposal must be received by March 11, 2013.

Other Stockholders Proposals — Discretionary Voting Authority and Bylaws

With respect to stockholder proposals not included in our company’s proxy statement and form of proxy, we may utilize discretionary authority conferred by proxy in voting on any such proposals if, among other situations, the stockholder does not give timely notice of the matter to us by the date determined under our By-laws for the submission of business by stockholders. This notice requirement and deadline are independent of the notice requirement and deadline described above for a stockholder proposal to be considered for inclusion in our proxy statement. Our Bylaws state that, to be timely, notice and certain related information must be received at the principal executive offices not later than the close of business on the 90th day prior to the first anniversary of the mailing of notice for the preceding year’s annual meeting. Therefore, to be timely under our Bylaws, a proposal for the 2013 annual meeting not included by or at the direction of the Board of Directors must be received no later than April 10, 2012.
