Northern Trust Accelerates Growth in Insurance Segment

Over US$95 billion in new insurance assets added globally since 2009; market-leading integrated insurance accounting solution delivered to clients

CHICAGO and LONDON, May 18, 2010 - Northern Trust (Nasdaq: NTRS) announced today that it has seen rapid
growth in delivering solutions to insurance companies, with new insurance
mandates accounting for a 20 percent increase in global insurance assets
serviced over the past 18 months. New clients and increased services to
existing clients are driving the growth as Northern Trust continues to
develop integrated solutions for custody, investment accounting and
operations outsourcing specifically for insurance clients.

Since January 2009, Northern Trust has added more than US$95 billion in
new insurance assets. With the addition of 16 new mandates in this segment
over this period, Northern Trust now services in excess of 230 insurance
relationships worldwide, with new business interest coming from across all
sectors of the market: general insurance, life assurance, pensions and
retirement savings, captive insurance, protection and indemnity, and the
specialist Lloyd's insurance market in the UK.

"Our insurance business has taken a quantum leap forward around the
world," said Sheldon Woldt, head of the Insurance Client segment of Northern
Trust's asset servicing business. "An important differentiator for Northern
Trust has been our end-to-end global servicing capability that encompasses
global custody, fund services, operational outsourcing solutions and asset
management services. Northern Trust also has a history of serving the
insurance segment and a focused business strategy that is aligned with the
evolving needs of a multifaceted industry."

Examples of recent insurance clients and solutions provided by Northern
Trust include:

    - KLP (Kommunal Landspensjonskasse), one of Norway's largest life
      insurance companies, selected Northern Trust and its partner,
      Handelsbanken, to provide custody and related services for assets
      managed on behalf of its funds and insurance businesses.
    - Navigators Insurance Company, a subsidiary of The Navigators Group,
      Inc., selected Northern Trust to provide global custody and investment
      accounting services for insurance assets for its UK branch.
    - ProMutual Group, a leading provider of medical liability insurance in
      the United States, chose Northern Trust to provide a full statutory
      accounting solution for its insurance investment portfolio.

"Northern Trust is committed to providing our insurance clients with
premier accounting and custody services," said Paul d'Ouville, global head of
Product Management for asset servicing at Northern Trust. "We have
established experienced insurance product and operations teams and
successfully deployed a solution that delivers customized investment
accounting, custody, performance measurement, risk measurement and compliance
reporting. With the completion of year-end statutory accounting for our
clients, we have delivered on our commitments."

In 2010, Northern Trust successfully completed year-end statutory and
GAAP accounting for ProMutual Group and another client utilizing its
outsourcing solution. Northern Trust's multi-basis accounting services
integrate BasisPoint, a technology platform developed by Pendo Systems, with
Northern Trust's global operating platform and its online portal, Passport.

Recent additions to the insurance team include Dennis Case, who joined as
global product manager for the insurance accounting and financial reporting
outsourcing solution, and Michael Dowd, senior product manager. Case came to
Northern Trust from Pendo Systems, where he headed operations, and was
formerly insurance product manager at Bank of New York Mellon in
Philadelphia. Dowd was formerly operations chief for QED Financial Systems,
Inc., which provides investment accounting services, and previously managed
the accounting and reporting functions for insurance clients of Mellon
Financial Corp.

Penelope Biggs, head of institutional business development for Europe,
Middle East and Africa at Northern Trust, said: "This is a global growth
story. We are seeing strong demand from all sectors of the insurance market,
as companies move forward after managing the challenges presented by the
financial markets during the last two years. These clients are looking to
Northern Trust for sophisticated solutions - from risk mitigation to
distribution support and guidance, to expertise around alternative assets. We
are committed to continuing to build new products and capabilities that help
our insurance clients drive their businesses forward."
