DataMirror Corporation: Sarbanes-Oxley November Deadline Looms: Is Your Company's Data in Compliance?

MARKHAM, Ontario -- DataMirror Webinar Offers Timely Insight on Meeting Sarbanes-Oxley's Internal Controls Requirements

DataMirror (Nasdaq: DMCX) (TSX: DMC), a leading provider of real-time, secure data integration solutions, will host a complimentary, live Webinar aimed at helping organizations understand how real-time data auditing can cost-effectively meet the internal controls required by Sarbanes-Oxley, specifically Sections 404, 409, and 802. The presentation, "Sarbanes-Oxley: Creating and Maintaining Effective Internal Controls," begins at 1:00 p.m. ET on Thursday, September 16, 2004.

A July 2003 study, "Compliance: A gap at the heart of risk management," commissioned by PriceWaterhouseCoopers found that less than one quarter of senior executives from financial institutions feel confident that their organization is in full compliance with regulatory requirements for internal controls. This is an unexpectedly low rate considering the November 15th deadline for Section 404 of the Sarbanes-Oxley (SOX) Act. Organizations are in need of clarity and information regarding how compliance can be achieved in a cost-effective and timely manner.

To meet this need, DataMirror continues to educate organizations on the benefits and impact of real-time data auditing in addressing a wide range of regulatory and compliance challenges. This Webinar will address the selection criteria for data auditing solutions, the timeframe within which organizations are expected to implement an effective internal controls plan, and the benefits organizations can expect to gain, beyond compliance, including improved financial accountability and strengthened investor, stakeholder, and public confidence. Participants will learn how to create and maintain effective internal controls as required by Section 404, how real-time data auditing can support the disclosure of data on a rapid and current basis as required by Section 409, how to create and retain sufficient audit trail information as outlined in Section 802, and how to integrate, record, and track financial and other disclosure-related information.
