Fair Isaac Global FICO Score Reaches New Market through Alliance with Korea Credit Bureau

Fair Isaac Corporation (NYSE:FIC), the leading provider of
analytics and decision management technology, today announced a
multi-year agreement with Korea Credit Bureau (KCB), the Republic of
Korea's premier provider of consumer credit information. KCB will
market and sell Fair Isaac's industry-proven Global FICO(R) score,
enabling lenders in that nation to sharpen their evaluation of
consumer risk, streamline decision processes and increase
profitability.

Global FICO score rank-orders consumers according to their credit
risk. Designed to be consistently scaled across credit bureaus and
across national borders, Global FICO score has established the global
standard for consumer credit risk assessment. The Fair Isaac
technology underlying the Global FICO scoring model enables quick
deployment in any country that has robust credit bureau data. Korea
Credit Bureau plans to provide Global FICO scores to financial
institutions and credit lenders starting in early 2007.

"Our alliance with Korea Credit Bureau opens a new chapter for
lenders in the Republic of Korea who serve the consumer credit
market," said Ron Totaro, vice president of Global Scoring at Fair
Isaac. "Global FICO score provides a way for lenders throughout the
country to quickly implement highly predictive risk assessment
solutions. By gaining better control of risk, they also can speed up
decision processes and increase their profits."

"Our member lenders founded the Korea Credit Bureau to improve the
quality of credit data in this market by sharing both positive and
negative data as advanced countries do," said Buhmsoo Choi, Ph.D. and
senior vice president of the credit evaluation department at Korea
Credit Bureau. "We expect that credit data of KCB will become more
powerful by being combined with Fair Isaac's proven, world-class
analytic science. By using Global FICO credit risk scores, it is
anticipated that lenders will be able to more accurately determine a
consumer's credit risk and can tailor their credit offerings to every
risk profile."

Fair Isaac developed its Global FICO score technology using
knowledge and experience it gained from analyzing a wide range of
credit data over many years. By addressing a variety of predictive
variables, the score technology accommodates a broad range of bureau
configurations and available data.

Global FICO(R) score may also assist lenders to meet their Basel
II and other regulatory compliance requirements. The scores are
complementary to custom application and behavior models, and can be
used alongside internal scores at all stages in the credit lifecycle
to improve decisions throughout the lending process, from marketing
and account origination to full portfolio management.
