Exhibit 99.1

Geac Sells Interealty Business to The First American Corporation

Company divests non-core asset to continue targeted focus on
enhancing Performance Management integration and sales

MARKHAM, Ontario and WALTHAM, Mass., October 3, 2005 – Geac^® (TSX:GAC, NASDAQ:GEAC) today announced that it has sold in an all cash sale of US$35 million its Interealty division, which specializes in Web-based applications for realtors, to The First American Corporation (NYSE:FAF), a Fortune 500 business information provider. Interealty will be added to First American Residential Group, a subsidiary business line established by First American in 2002 to address the real estate brokerage, multiple listing service (MLS) and relocation market segments with the full array of First American capabilities.

Interealty is a leading service provider to the residential retail real estate market with innovative products such as its MLS systems, MLXchange and MLXchange Professional. Over the past several years, Geac’s management team has revitalized the Interealty business and significantly improved operating performance. However, Geac recognizes that by focusing on its core Performance Management strategy, it can best achieve the highest value for its customers, shareholders and other stakeholders.

“While a formidable player in the residential retail real estate market, Interealty is not core to our Performance Management integration strategy. It is, however, a complementary and strategic asset for First American’s business,” said Charles Jones, President and CEO of Geac. “Geac is increasingly focused on how its Performance Management technology can integrate with existing Geac applications to assist in differentiating our many product lines. We have seen particular success with Geac product integration initiatives across our Enterprise Applications business and within the Industry Specific Applications – including integration with our Local Government and Commercial Systems Divisions and market opportunities identified for our Restaurants Division. Geac is also focused on how these important applications can integrate with non-Geac products to provide world class

financial management solutions on a broad base of existing transaction and operating systems. With both Geac and non-Geac product integration initiatives, we have witnessed sales of our Performance Management suite increase with existing and new customers.”

Mr. Jones continued, “Today’s sale is also a strong example of our ability to turn around challenged businesses and to achieve solid market value for non-strategic assets. Two years ago, Interealty was in decline and losing money. Through the strong focus of Geac management and the extraordinary efforts of the Interealty team, we have transformed this business. We have sold Interealty, a non-strategic asset to Geac, in an all cash transaction valued at a multiple of 1.5 times trailing revenues to a Fortune 500 company that will provide increasing strategic opportunities for this thriving enterprise and its dedicated and talented employee base.

Headquartered in Santa Ana, Calif., First American Residential Group, Inc., provides service, technology, outsourcing and product solutions to members of the real estate and relocation industries. Working in concert with other First American units, the company provides a comprehensive portfolio of residential real estate services including transaction management, title insurance, home warranty, appraisal and relocation services.

“We’re pleased to bring aboard the leading products and strong people of Geac’s Interealty business,” said Stephen C. Roney, president and chief executive officer of First American Residential Group. “We are equally delighted to welcome their many customers to the unparalleled tradition, innovation and standard of care that are the hallmarks of First American.”

The US$35 million purchase price is subject to a post-closing working capital and capital expenditure adjustment as of the closing date. Under the terms of the agreement, Geac will provide certain transitional services after the close of the transaction. Employees of Interealty will be offered employment with First American Residential Group, and Interealty’s management, office locations, company name and product brands will remain unchanged.
