Northern Trust Expands Capabilities for Independent Valuations of OTC Derivatives

Allliance with Numerix Focuses on Structured and Custom Securities

CHICAGO, January 5 - Northern Trust announced today that it has enhanced its platform for
processing over-the-counter (OTC) derivatives to provide daily independent
pricing for structured products and other bespoke instruments. The expanded
capabilities, including transparency reporting for OTC instrument types, were
developed through a strategic alliance with Numerix, a leading derivative and
structured products valuation and analytics company.

"The derivatives industry, regulators, investors and our clients globally
are demanding increasing independence and transparency for OTC derivative
valuations," said Peter Cherecwich, chief operating officer for Corporate &
Institutional Services at Northern Trust. "Derivatives perform critical
functions for investment managers and institutional investors, and our global
alliance with Numerix brings a range of valuation capabilities and depth of
knowledge to help our clients exercise greater control over valuation of
these assets while meeting the standard for transparency demanded by
sophisticated investors."

The enhancements allow Northern Trust to independently price exotic OTC
derivative instruments and provide clients access to the mathematical model,
calibration techniques and market data components of the pricing process to
enable fully transparent reporting.

Specifically focused on hedge funds, investment managers and institutions
requiring daily independent pricing for structured products, these
capabilities are delivered to clients globally through Northern Trust's
integrated derivatives processing platform. In addition, Numerix financial
engineers work alongside the derivative pricing teams at Northern Trust
operation centers throughout the globe to provide clients with access to the
highest level of valuation support.

Numerix is a leading independent analytics provider for derivatives and
structured products and currently performs more than two million valuations
per year. Numerix pricing models and software solutions are utilized by

services firms," said Steve O'Hanlon, CEO/President at Numerix. "Through this

valuations, innovative transparency reporting and access to expertise that is
