Northern Trust Supports Fair Value NAV Pricing for EMEA Clients

Automated system takes into account market events in other time zones when calculating NAV

LONDON, May 27, 2010 - Northern Trust (Nasdaq: NTRS) has implemented a daily Fair Value NAV
Pricing tool for its fund management and institutional clients in Europe,
Middle East and Africa (EMEA). Through an automated system, Northern Trust
can fair value securities on a daily basis to deliver NAV (Net Asset Value)
unit prices significantly reducing opportunities for market timing in
different time zones and after markets close.

"Fair Value NAV Pricing enables investors to gain a much clearer picture
of the estimated value of the securities in their portfolio by taking into
account the time between the investment market being closed and the NAV
valuation point," said Mark Schoen, head of global product and strategy for
EMEA at Northern Trust.

"This is an important tool, particularly where securities are traded in
multiple markets, as it applies a standard adjustment to the closing price
which is more accurate than other pricing methods," he added.

Factors are applied to the closing prices to create a new fair value
price, which is used to calculate the fund's NAV. Clients can also receive
reports that enable them to analyze the effect of Fair Value NAV Pricing on
their funds and underlying securities.

"We are seeing an increasing demand from clients in Europe, particularly
fund managers, for Fair Value NAV Pricing," said Peter Cherecwich, global
chief operating officer for Northern Trust's asset servicing business.
"Around 90 percent of US mutual funds investing internationally are fair
valued on a daily basis and this trend is spreading to EMEA, particularly as
a result of market volatility."

Northern Trust's Fair Value NAV Product suite also caters for the fair
valuing of annual financial statements around IFRS 7 and FAS 157.
