WALTHAM, Massachusetts, May 5 /PRNewswire/ --

Lewtan Technologies, Inc., provider of ABSNet, the industry's leading
source for asset-backed securities surveillance data, analytics, software,
and content for the global securitisation industry, today announced that
Thomson Reuters will utilize its ABSNet cashflow library to expand their
Valuation Risk Service. This will give Thomson Reuters clients additional
coverage of structured finance instruments in Europe in order to help
strengthen transparency and develop better evaluated prices in the
marketplace in light of the current financial crisis.

"The selection of our ABSNet library by Thomson Reuters is another
example of Lewtan's commitment to increasing transparency in the structured
finance market," said Ned Myers, Chief Marketing Officer of Lewtan. "Market
transparency of prices and challenges with the mark-to-market model are on
the forefront. With the structured finance community left to continue pricing
most bonds on a Level 3 basis under FAS157, investors have had to interpret
wide fluctuations in derivatives market prices, internal valuation models,
and third-party valuations to determine the value of their portfolios. The
combination of ABSNet's data and deal models with Thomson Reuters pricing
expertise will provide more credible prices when a mark-to-model price is
required."

Karl Mackelburg, Global Head of Structured Finance and Derivative
Pricing, said: "The opaque nature of the world's structured finance markets
has driven demand for robust, independent, evaluated prices. Working with
Lewtan supports Thomson Reuters goal of incorporating external market
expertise to provide greater coverage and accuracy, especially on difficult
to value assets."

Thomson Reuters is utilising Lewtan's ABSNet Cashflow library to provide
model support in conjunction with observable price data for the broadest
European MBS coverage. Market dislocation in global ABS/MBS/CMBS bond prices
has required investors to acquire additional data on both the evaluated
prices themselves and underlying credit performance. Lewtan provides both
deal models to form independent pricing valuations as well as underlying
credit performance data on both the bonds and the collateral supporting these
transactions.

Neither Lewtan Technologies nor Thomson Reuters owns, offers, sells or
originates any structured finance securities, which alleviates any potential
conflict of interest.
