Company Press Release CHICAGO, Sept. 29 /PRNewswire-FirstCall/ -- Northern Trust Corporation today announced three actions to support clients in light of the current turbulent market conditions.

"The hallmark of Northern Trust has always been our financial strength and client focus. With today's actions, we are putting Northern Trust's financial strength to work for our clients during extraordinarily challenging market conditions," said Frederick H. Waddell, President and Chief Executive Officer. "Times of economic stress reinforce the value of the consistent, conservative management practices that have served Northern Trust clients and shareholders well for nearly 120 years."

Northern Trust expects to incur pre-tax charges of approximately $525 million ($328 million after-tax or $1.46 per share) in the third quarter in connection with these three actions.

Northern Trust will increase the support provided for certain cash investment funds previously covered through capital support agreements (as announced February 22, 2008, and amended July 15, 2008) and will add one additional fund to this coverage. The capital support levels provided by Northern Trust will increase in aggregate by $321 million, to a maximum capital contribution of $550 million. These measures will enable the funds to continue to maintain a stable net asset value of $1.00. Northern Trust expects to incur a pre-tax charge of approximately $290 million ($181 million after-tax or $.80 per share) in the third quarter in connection with this action.

Cash investment funds impacted by this enhanced support include:

Northern Institutional Funds Diversified Assets Portfolio, Prime Obligations Portfolio and Liquid Assets Portfolio, as well as Northern Funds Money Market Fund, all of which are registered money market funds;

The Sterling Fund and the US Dollar Fund of Northern Trust Global Funds plc, both of which are pooled cash funds organized as Undertakings for the Collective Investment of Transferable Securities (UCITS); and

The NTGI Collective Short Term Investment Fund and The Northern Trust Company Common Short Term Investment Fund, both of which are commingled cash funds.

Northern Trust also will take certain actions to provide support for securities lending clients whose cash collateral is invested in five constant dollar, commingled investment pools negatively impacted by recent market events. Northern Trust expects to incur a pre-tax charge of approximately $150 million ($94 million after-tax or $.42 per share) in the third quarter in connection with this action.

Northern Trust also announced today that it will put in place a program offering to purchase certain illiquid auction rate securities that were purchased through Northern Trust for Personal Financial Services (PFS) clients under investment discretion or that were acquired by PFS clients from Northern Trust's affiliated broker/dealer. The terms of the offer will be communicated to those clients who qualify for the program. Northern Trust expects to incur a pre-tax charge of approximately $85 million ($53 million after-tax or $.24 per share) in the third quarter in connection with this action.

"We believe these actions reflect both our longstanding and well known commitment to helping our clients, as well as the financial strength of Northern Trust," Waddell said.
