13D

This Schedule 13D ( “Schedule 13D”) relates to shares of Common Stock, $0.001 par value per share (the “Common Stock”), of Actuate Corporation, a Delaware corporation (the “Issuer”). The address of the principal executive offices of the Issuer is BayCenter Campus, 951 Mariners Island Boulevard, San Mateo, CA 94404.

This Schedule 13D is being filed by Open Text Corporation, a Canadian corporation (the “Reporting Person”). The address of the principal business and principal offices of the Reporting Person is 275 Frank Tompa Drive, Waterloo, Ontario, Canada N2L OA1. The Reporting Person is the world’s largest independent provider of Enterprise Content Management software.

The Reporting Person is the sole stockholder of Asteroid Acquisition Corporation, a Delaware corporation (“Merger Sub”) and Open Text Holdings, Inc., a Delaware corporation, which is the sole stockholder of Open Text USA Inc., a Delaware corporation, which is the sole stockholder of Open Text, Inc., a Delaware corporation (“OTEX Inc”). OTEX Inc. holds the 1,445,290 shares of Common Stock reported herein.

The name, business address, present principal occupation or employment and citizenship of each executive officer and director of the Reporting Person and the name, principal business and address of any corporation or other organization in which such employment is conducted is set forth in Schedule A hereto and is incorporated herein by reference.

During the past five years, neither the Reporting Person nor, to the knowledge of the Reporting Person, any of the persons listed on Schedule A hereto (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The total amount of funds required to acquire 1,445,290 shares of Common Stock was approximately $6.5 million, which was obtained from cash on hand.

The total amount of funds required by the Reporting Person to acquire the Issuer, including the purchase of Shares (as defined below) pursuant to the Merger Agreement described in Item 4 and the Merger (as defined below), is estimated to be approximately $330 million. The Reporting Person will obtain funds from cash on hand and/or cash generated from general corporate activities in the ordinary course of business to fund the Offer Price (as defined below) and the Merger Consideration (as defined in the Merger Agreement).

As a result of the execution of the Tender and Voting Agreement (as defined below), the Reporting Person may be deemed to have acquired beneficial ownership of 4,117,447 Shares (as defined below) to the extent provided therein. The Tender and Voting Agreement was entered into as a condition to the Reporting Person’s and Merger Sub’s willingness to enter into and perform their obligations under the Merger Agreement (as defined below). The Reporting Person and Merger Sub requested that each Stockholder (as defined below) enter into the Tender and Voting Agreement, and each Stockholder agreed to do so in order to induce the Reporting Person and Merger Sub to enter into, and in consideration of their entering into, the Merger Agreement. The Reporting Person did not pay any consideration to the Stockholders in connection with the execution and delivery of the Tender and Voting Agreement. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by the Reporting Person that it is the beneficial owner of any of the 4,117,447 Shares for purposes of Section 13(d) of the Exchange Act or for any other purpose and such beneficial ownership thereof is expressly disclaimed

The information set forth or incorporated by reference in Item 4 is incorporated herein by reference.

In connection with its contemplation of a potential transaction, the Reporting Person (through OTEX Inc.) acquired 1,445,290 shares of Common Stock in open market purchases.

Merger Agreement

On December 5, 2014, the Reporting Person, Merger Sub and the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, and on the terms and subject to the conditions thereof, among other things, Merger Sub will commence a tender offer (the “Offer”) no later than December 16, 2014 to acquire all outstanding shares of Common Stock, including the associated preferred stock purchase rights issued under the Issuer’s rights agreement (“Shares”), at a purchase price of $6.60 per Share net to the seller in cash (the “Offer Price”), without interest thereon and subject to any required withholding taxes.

The obligation of Merger Sub to consummate the Offer is conditioned upon (i) there having been validly tendered and not withdrawn prior to the expiration of the Offer that number of Shares that would represent at least a majority of Shares then outstanding but excluding Shares that are owned as of the date of the commencement of the Offer by the Issuer, the Reporting Person or any direct or indirect wholly-owned subsidiaries of the Issuer or the Reporting Person and excluding any Shares tendered by notice of guaranteed delivery but not actually delivered to the depositary prior to the expiration time of the Offer, (ii) the expiration or termination of the waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any rules and regulations promulgated thereunder, (iii) no Company Material Adverse Effect (as defined in the Merger Agreement) having occurred following the date of the Merger Agreement and (iv) the satisfaction of other customary conditions.

As soon as practicable following consummation of the Offer and the satisfaction or waiver of certain conditions and without a stockholder vote to adopt the Merger Agreement or to effect the Merger in accordance with Section 251(h) of the Delaware General Corporation Law, Merger Sub will be merged with and into the Issuer (the “Merger”) and the Issuer will be the surviving corporation (the “Surviving Corporation”) and a wholly-owned subsidiary of the Reporting Person.

At the consummation of the Merger, the Issuer is required to deliver to the Reporting Person evidence reasonably satisfactory to the Reporting Person of the resignation of the directors of the Issuer and its subsidiaries (other than directors of the Issuer’s subsidiaries whom the Reporting Person determines shall continue to serve in such capacities following the date and time at which the Merger becomes effective (the “Effective Time”)), effective at the Effective Time. Pursuant to the Merger Agreement, the board of directors of the Surviving Corporation, effective as of, and immediately following, the Effective Time will consist of the directors of Merger Sub and the officers of the Surviving Corporation will consist of the Issuer’s officers immediately prior to the Effective Time.

At the Effective time, the certificate of incorporation of the Issuer will be amended and restated as set forth in Exhibit B to the Merger Agreement, and as so amended and restated will be the certificate of incorporation of the Surviving Corporation. Also at the Effective Time, the bylaws of Merger Sub will be the bylaws of the Surviving Corporation.

Upon the consummation of the Merger, each share of common stock of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and become one fully paid, nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation, which shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Pursuant to Section 12(g)(4) of the Securities Act of 1933, as amended, at the Effective Time, the shares of Common Stock will become eligible for deregistration and the Reporting Person will cause the shares of Common Stock to be deregistered. In addition, the Reporting Person will cause the shares of Common Stock to be delisted from the Nasdaq Global Select Market.

Tender and Voting Agreement

Concurrently with the execution and delivery of the Merger Agreement, on December 5, 2014, Peter I. Cittadini, President, Chief Executive Officer and a director of the Issuer, Arthur C. Patterson, the Issuer’s lead independent director, and certain of their affiliates (each, a “Stockholder” and, collectively the “Stockholders”) entered into the Tender and Voting Agreement (the “Tender and Voting Agreement”) with the Reporting Person and Merger Sub pursuant to which each such person or entity agreed, among other things, to tender his or its Shares pursuant to the Offer and to vote against (i) any competing Acquisition Proposal (as defined in the Merger Agreement) or any proposal relating to any Acquisition Proposal, (ii) any merger (other than the Merger), consolidation or other combination involving the Issuer or any of its subsidiaries or a reorganization, recapitalization, extraordinary dividend, dissolution or liquidation of the Issuer or any of its subsidiaries, (iii) to the extent submitted to a stockholder vote, any change in the business, management or board of directors of the Issuer (other than as directed by the Reporting Person, Merger Sub or any the Reporting Person subsidiary) or (iv) any other action, proposal or agreement that would (A) reasonably be expected to impede, interfere with, materially delay or postpone the Merger and the other transactions contemplated by the Merger Agreement, (B) result in any of the Offer Conditions (as described in the Merger Agreement) or conditions to the Merger not being fulfilled or satisfied or (C) change in any manner the dividend policy or capitalization of, including the voting rights of any class of equity security interests in, the Issuer.

The Tender and Voting Agreement terminates upon the earlier of (a) the termination of the Merger Agreement in accordance with its terms, (b) the consummation of the Offer, (c) any modification to the terms of the Offer for which the Issuer’s consent is required and to which the Issuer has not consented and (d) the mutual written agreement of the parties thereto to terminate the Tender and Voting Agreement.

As of December 12, 2014, the Stockholders collectively owned a number of Shares equal to approximately 8.8% of the issued and outstanding Shares. In addition, the Stockholders collectively hold (as of December 12, 2014) options (whether vested or unvested) and restricted stock units (whether unvested or vested but deferred) for an aggregate of 2,388,560 Shares. If a Stockholder acquires Shares that are subject to the Tender and Voting Agreement, then those Shares would also be subject to the terms of the Tender and Voting Agreement.

The foregoing description of the Tender and Voting Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Tender and Voting Agreement which is attached to this Schedule 13D as Exhibit 2 and incorporated herein by reference.

The Merger Agreement and the Tender and Voting Agreement have been provided solely to inform investors of their terms. They are not intended to be, and should not be relied upon as, a source of financial, business or operational information about the Issuer, the Reporting Person, Merger Sub or their respective affiliates. The representations and warranties contained in the Merger Agreement and the Tender and Voting Agreement are made only for purposes of the Merger Agreement and the Tender and Voting Agreement, respectively, and are made as of specific dates; are solely for the benefit of their respective parties; may be subject to qualifications and limitations agreed upon by the parties to such agreement in connection with negotiating the terms of such agreement, including being qualified by confidential disclosures made for the purpose of allocating contractual risk between the parties instead of establishing matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors or security holders. Moreover, information concerning the subject matter of the representations, warranties, covenants and certain closing conditions may change after the date of the Merger Agreement and the Tender and Voting Agreement, as applicable, which subsequent information may or may not be fully reflected in public disclosures. The representations and warranties in the Merger Agreement and/or the Tender and Voting Agreement also may not be accurate or complete as of any specified date and may be subject to a contractual standard of materiality different from those generally applicable to stockholders. The representations and warranties contained in the Merger Agreement and incorporated by reference into this Schedule 13D have been negotiated with the principal purpose of establishing the circumstances in which Merger Sub may have the right not to consummate the Offer, or a party may have the right to terminate the Merger Agreement, if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and to allocate risk between the parties, rather than establish matters as facts. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this

Page 5 of 11 Pages

Schedule 13D, may have changed since the date of the Merger Agreement and the Tender and Voting Agreement and subsequent developments or new information qualifying a representation or warranty may not be included in this Schedule 13D.

Confidentiality Agreement

Prior to entering into the Merger Agreement, the Issuer and the Reporting Person entered into a Mutual Non-Disclosure Agreement, dated as of July 24, 2014 (as amended, the “Confidentiality Agreement”). As a condition to being furnished confidential information of the Issuer, the Reporting Person agreed, among other things, to keep such confidential information confidential and to use it only for specified purposes. The Confidentiality Agreement also contained customary “standstill” provisions that prohibit the Reporting Person, until May 31, 2015, from taking the following actions:

However, the Reporting Person was permitted to purchase securities so long as it does not result in an aggregate ownership by the Reporting Person of more than 5% of the outstanding amount of any class of securities of the Issuer or of any of its affiliates. In addition, the Reporting Person was not prohibited from (1) making any proposal to the Issuer’s board of directors that would not reasonably be expected to require a public announcement by the Issuer or (2) requesting that the Issuer, directly or indirectly, waive or amend any of the provisions of the standstill provisions. The Issuer agreed that any non-disclosure agreement it or its affiliates had entered into or would enter into with a third party to explore a potential transaction for the sale of more than 50% of the Issuer’s outstanding voting equity securities, or a sale of substantially all of the Issuer’s assets, has or would have “standstill” provisions substantially similar to the provisions described above.

In addition, the Confidentiality Agreement contains a non-solicitation provision, prohibiting the Reporting Person, during the one year period commencing on the date of the Confidentiality Agreement, from soliciting for employment any key employee or executive officer of the Issuer or its subsidiaries with whom the Reporting Person had contact or became aware of in connection with a possible transaction (subject to certain exceptions described in the Confidentiality Agreement). Under the Merger Agreement, the Confidentiality Agreement expressly remains in

full force and effect. The foregoing summary is qualified in its entirety by reference to the complete text of the Confidentiality Agreement, which is attached to this Schedule 13D as Exhibit 3 and incorporated herein by reference.

Other than as described in this Item 4, the Reporting Person currently has no plans or proposals that relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D.

2. The Receiving Party agrees (a) to hold the Disclosing Party’s Proprietary Information In strict confidence and to take all reasonable precautions to protect such Proprietary Information (including, without limitation, all precautions that Receiving Party employs with respect to its confidential materials), (b) not to divulge any such Proprietary Information or any information derived therefrom to any third person without prior written permission of the Disclosing Party, excluding disclosure to Representatives, (c) not to make any use whatsoever at any time of such Proprietary Information except to evaluate internally whether to enter into the contemplated business relationship with the Disclosing Party, and (d) not to copy or reverse engineer any such Proprietary Information. Any employee given access to any such Proprietary Information must have a legitimate “need to know” and be subject to restrictions on disclosure of Proprietary Information practically identical to the terms set forth herein. Without granting any right or license, the Disclosing Party agrees that the foregoing clauses (a), (b) and (c) shall not apply with respect to any information that (i) is or (through no improper action or inaction by the Receiving Party or any agent, consultant or employee) becomes generally available to the public, or (ii) was or is rightfully in Receiving Party’s possession or the possession of any of its Representatives or was known by it or its Representatives without restriction prior to receipt from the Disclosing Party, or (iii) was or is rightfully disclosed to Receiving Party or any of its Representatives by a third party provided the Receiving Party complies with restrictions imposed by the third party, or (iv) was or is independently developed without

use of any Proprietary Information of the Disclosing Party. The Receiving Party and its Representatives may make disclosures required by court order or any legal or judicial process, without any liability hereunder, provided the Receiving Party uses reasonable efforts to limit disclosure and to obtain confidential treatment or a protective order and has allowed the Disclosing Party to participate In the proceeding to the extent legally permissible and reasonably practicable.

4. Except to the extent required by law, neither party shall disclose the existence or subject matter of the negotiations or business relationship contemplated by this Agreement.

5. The parties acknowledge and agree that due to the unique nature of the possible transaction between the parties, there can be no adequate remedy at law for any material breach of this Agreement, that any such breach may allow the breaching party or third parties to unfairly compete with the non-breaching party, resulting in irreparable harm to the non-breaching party, and therefore, that upon any such breach or any threat thereof, the non-breaching party shall be entitled to seek appropriate equitable relief in addition to whatever remedies it might have at law. The Receiving Party will notify the Disclosing Party In writing immediately upon the occurrence of any unauthorized release or other breach of which it is aware.

The parties expressly agree that neither the terms or conditions of this Agreement, nor the discussions held by the parties to address the feasibility of a potential business relationship shall be construed as to prevent either party from pursuing similar discussions with third parties in similar markets or obligate either party to take, continue or forgo any action relating to the above-mentioned discussions. Further, nothing in this Agreement shall be construed as prohibiting or restricting either party from independently developing, acquiring, and marketing products, services, and other materials, which are similar to or competitive In any geographic area and in any form with the other party’s product(s) or service(s). However, this paragraph shall not be deemed to grant to either party any license under the other party’s copyrights or patents.
