# Experian is reporting in US dollars


In the six months to 31 March 2007, sales from continuing activities at Experian
increased by 12% at constant exchange rates. Organic growth was 8%, consistent
with the rate in the first half of the year (7%).

Globally in the second half, there was continued strong double-digit organic
growth in Decision Analytics and Interactive, Credit Services returned to mid
single-digit growth and Marketing Solutions sales were in line with last year on
an organic basis. Acquisitions contributed 4% to sales growth in the period.

Experian acquired five businesses during the half - a business and consumer
credit bureau in Estonia, an additional US affiliate credit bureau, a US
business information distributor, Adhoc Solutions (Belgian micromarketing) and
ERS, a UK-based economic research consultancy. Experian also purchased a
minority stake in Sinotrust, a business information and market research company
in China and, after the year end, acquired Informarketing, a direct marketing
services provider in Brazil.

Americas
In dollars, sales in the Americas from continuing activities in the six months
to 31 March 2007 increased by 12% in total. Organic growth was 9%, with
PriceGrabber, which was acquired in mid-December 2005, generating the remaining
3%.

Credit Services saw mid single-digit organic growth in the second half, with
particularly good performances in account management and collections within
consumer credit and good growth elsewhere in business information and
automotive. Decision Analytics again performed strongly in the second half,
while sales in Marketing Solutions were marginally down year-on-year.

Organic sales growth at Interactive was slightly less than 20% in the second
half of the year, with the deceleration in the fourth quarter reflecting the
impact on LowerMyBills of the slowdown in the US sub-prime mortgage market.
Sales at LowerMyBills were down 5% in the second half (Q3: unchanged; Q4: down
8%). The other Interactive businesses performed strongly in the period.

UK and Ireland
Sales from continuing activities in the UK and Ireland increased by 14% in the
second half at constant exchange rates. Organic growth was 6%, with
acquisitions, mainly ClarityBlue (acquired in January 2006) and Eiger Systems
(acquired in June 2006), contributing the balance.

The environment for UK financial services companies was again challenging, which
affected both Credit Services and Marketing Solutions. Credit Services showed
low single-digit organic sales growth in the half. Marketing Solutions was in
line with last year, including a strong organic growth performance from
ClarityBlue, partly offset by the impact of major new contracts in the second
half of last year at QAS. Decision Analytics delivered another consistent period
of high single-digit sales growth, with continued momentum in fraud prevention.
Interactive sales more than doubled in the half.

In March 2007, Experian announced its intention to integrate its UK marketing
data, processing and database management activities into a single business unit.
Customers will benefit from one point of contact with Experian across one
technology platform. As a result, there will be a headcount reduction over time
of about 100, in areas such as sales, delivery and systems. Restructuring costs,
which will be charged against EBIT, are expected to be about $12m, of which
about $8m has been incurred in the year ended 31 March 2007, with the balance in
the current financial year.

EMEA/Asia Pacific
At constant exchange rates, sales in EMEA/Asia Pacific increased by 9% in the
half, of which organic growth contributed 8%. Credit Services sales accelerated
in the second half, driven by stronger growth in French transaction processing.
This reflects the first time contribution of contract wins during the year and
continued double-digit increases from the consumer credit bureaux in Southern
and Eastern Europe and South Africa. Both Decision Analytics and Marketing
Solutions delivered double-digit sales growth in the period.

Future announcements
Experian will announce its Preliminary Results on 23 May 2007. Its First Quarter
Trading Update will be announced on 12 July 2007.
