Fair Isaac Names Dr. Mark Greene to CEO Post

Greene most recently served as vice president of sales and distribution for Financial Services at IBM, responsible for setting business development strategy and driving growth across the $24 billion banking, financial markets and insurance industry segment. Prior to that, he served for four years as general manager of IBM's Global Banking unit, the company's largest industry vertical, with responsibility for driving performance of the company's $14 billion, worldwide business portfolio of 1.200 banking clients. Before that, he led strategy and business development for IBM's Financial Services Strategy and Solutions division.

"After a thorough search process involving many strong candidates, Fair Isaac's board and executive leadership team enthusiastically agreed that Mark Greene is the right person to lead the company," said A. George (Skip) Battle, Fair Isaac's chairman of the board. "Mark is a proven leader who brings extensive global experience, a track record of driving growth, and genuine enthusiasm for Fair Isaac's people, technologies and vision. We're confident in Mark's ability to create more opportunities and value for our customers, employees and shareholders."

"Mark has built his reputation on his ability to inspire and lead growing, ambitious organizations to new heights of success," said Charles Osborne, interim CEO and chief financial officer at Fair Isaac. "He's also a technologist with a natural appreciation for the innovation, creativity and power built into our unique brand of technology - and he has a deep working knowledge of analytics. So, he's a great DNA match for Fair Isaac."

Earlier in his IBM career, Greene served as vice president of IBM's SecureWay software business group, focused on e-business infrastructure products, and played a central role in developing IBM's electronic commerce software strategy as co-founder of the company's e-commerce initiative now known as IBM WebSphere. Prior to joining IBM, he served in leadership roles with companies including Technology Solutions Company (New York, NY), Berkeley Investment Technologies and Citicorp. He began his career in 1982 as an economist with the Federal Reserve Board.

"It's an honor to join a truly great company that, through 50 years of relentless innovation, has had a profound and enduring impact on how businesses make decisions," said Greene. "Through my work in the banking and insurance industries, I'm very familiar with Fair Isaac and its remarkable role in the growth of global financial markets. I'm confident that we will have an even greater impact on how businesses in many industries make decisions in the future, and I look forward to joining forces with the exceptional people across this organization to accelerate the growth of Fair Isaac around the world."

Greene will assume his new duties immediately. He succeeds interim CEO Osborne, who will remain with the company as chief financial officer, a position he has held since 2004. Osborne assumed the role of interim CEO in November, 2006, following the resignation of former CEO Thomas Grudnowski.
