As further described in the Prospectus Supplement dated November 17, 2010, Northern Trust Investments, N.A., as trustee (the “Trustee”) of the American Bar Association Members/Northern Trust Collective Trust, is restructuring the Stable Asset Return Fund, an investment option offered under the ABA Retirement Funds Program, effective on or about December 8, 2010. In connection therewith, effective December 8, 2010, the Trustee entered into Investment Advisor Agreements with Galliard Capital Management, Inc. (“Galliard”), Jennison Associates LLC (“Jennison”) and Pacific Investment Management Company, LLC (“PIMCO”), pursuant to which Galliard, Jennison and PIMCO, respectively, will provide investment advisory services with respect to portions of the Stable Asset Return Fund. The Trustee previously retained Jennison and PIMCO to provide investment advisory services with respect to the Large Cap Equity Fund and the Bond Core Plus Fund, respectively. As of December 8, 2010, approximately 54%, 17% and 15% of the assets of the Stable Asset Return Fund were allocated to Galliard, Jennison and PIMCO, respectively. In addition, as of December 8, 2010, approximately 14% of the assets of the Fund were allocated to the NTGI Collective Government Short-Term Investment Fund, which provides a “liquidity buffer” for the Stable Asset Return Fund. The Investment Advisor Agreements referred to above are incorporated herein by reference thereto.

In connection with the restructuring of the Stable Asset Return Fund, as more fully described in Item 1.01 above, effective as of the close of business on December 7, 2010, the Trustee terminated the Investment Management Agreement dated as of July 1, 2010 between the Trustee and State Street Global Advisors, a division of State Street Bank and Trust Company (“State Street Bank”), pursuant to which State Street Bank provided investment advisory services with respect to the Stable Asset Return Fund.

In connection with the restructuring of the Stable Asset Return Fund, as more fully described in Item 1.01 above, effective December 8, 2010, the Trustee entered into a Tenth Amended and Restated Fund Declaration for the Stable Asset Return Fund. The Fund Declaration is incorporated herein by reference thereto.
