IBM Corp. has agreed to buy a British analytical software company that employs about 100 people at an office in Tucson.

IBM's acquisition of i2 Holdings Ltd., a global provider of intelligence analytics for crime and fraud prevention, is expected to close in the fourth quarter. Financial terms were not disclosed.

The seller is California-based investment fund Silver Lake Sumeru, which bought i2 from ChoicePoint Inc. for $185 million in 2008.

The Tucson operation formerly was Knowledge Computing Corp., a University of Arizona technology spinoff acquired by i2 in 2009.

No operational changes are planned for i2, and its employees will remain in their current offices, IBM spokeswoman Nancy Kaplan said.

The company, whose local office is at 7750 E. Broadway, will become part of IBM's Industry Solutions group, Kaplan said.

IBM is one of the region's biggest employers, with about 1,350 workers at a major computer storage-systems development center at the University of Arizona Science and Technology Park.

I2 is based in Cambridge, England, has 350 employees overall and has its U.S. headquarters in McLean, Va. Its clients span industries including banking, defense, health care, insurance, law enforcement, national security and retail.

"The combined capabilities of IBM and i2 will help customers uncover patterns and trends that will allow them to more effectively protect the privacy and safety of citizens, businesses and governments," said Craig Hayman, general manager of IBM Industry Solutions, in prepared remarks.

Analytical software maker i2 arrived in Tucson in 2009, when the company acquired Knowledge Computing Corp., developer of Coplink database-sharing software used by many law-enforcement agencies.

Knowledge Computing was founded in 2000 by Hsinchun Chen, a University of Arizona professor and director of the UA's Artificial Intelligence Laboratory, which he still heads.
