EXPLANATORY NOTE

Deregistration of Securities

This Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 (No. 333-34410), as amended (the “Registration Statement”), is being filed to remove from registration all unsold securities of Actuate Corporation (the “Company”) registered under the Registration Statement.

On December 5, 2014, the Company, Open Text Corporation, a Canadian Corporation (“OpenText”), and Asteroid Acquisition Corporation, a Delaware wholly owned subsidiary of OpenText (“Purchaser”), entered into an Agreement and Plan of Merger (the “Agreement”). The Agreement contemplated that Purchaser would be merged with and into the Company (the “Merger”) and that the Company would survive the Merger as a wholly owned subsidiary of OpenText. The Merger became effective on January 16, 2015 (the “Effective Date”) as a result of filing a Certificate of Merger with the Secretary of State of the State of Delaware.

As of the Effective Date, each share of common stock of the Company issued and outstanding immediately prior to the Merger (other than each share (i) owned by OpenText or Purchaser or held by a wholly-owned subsidiary of OpenText or the Company, which will be cancelled and cease to exist without any payment being made with respect to such share or (ii) owned by the Company’s stockholders who are entitled to and who properly exercised appraisal rights under Section 262 of the Delaware General Corporation Law with respect to such share) was cancelled and converted into the right to receive $6.60 in cash, without interest thereon and less any required withholding taxes.

As a result of the Merger, the Company has terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by the Company in the Registration Statement to remove from registration by means of a post–effective amendment any securities registered under the Registration Statement which remain unsold at the termination of the offering, the Company hereby removes from registration any securities registered under the Registration Statement which remained unsold as of the Effective Date.
