Item 1. Schedule of Investments.

Cadre Institutional Investors Trust (the "Trust") is comprised of seven series as follows: Cadre Liquid Asset Fund - Money Market Series, Cadre Reserve Fund - U.S. Government Series, Cadre Reserve Fund - Money Market Series, SweepCash Fund - U.S. Government Series, SweepCash Fund - Money Market Series, U.S. Government Money Market Portfolio and Money Market Portfolio. The SweepCash Fund - U.S. Government Series and SweepCash Fund - Money Market Series have not yet commenced operations.

Cadre Liquid Asset Fund - Money Market Series and the Cadre Reserve Fund - Money Market Series (collectively the “Money Market Feeder Funds”) invest all of their investable assets in the Money Market Portfolio (the “Money Market Master Portfolio”). The Money Market Master Portfolio is a series of the Trust that has substantially the same investment objectives, policies and restrictions as the Money Market Feeder Funds. The value of the Money Market Feeder Funds’ investments in the Money Market Master Portfolio reflects each Money Market Feeder Fund’s proportionate interest in the net assets of the Money Market Master Portfolio.

Cadre Reserve Fund - U.S. Government Series invests all of its investable assets in the U.S. Government Money Market Portfolio (the “U.S. Government Master Portfolio”). The U.S. Government Master Portfolio is a series of the Trust that has substantially the same investment objectives, policies and restrictions as Cadre Reserve Fund - U.S. Government Series. The value of Cadre Reserve Fund - U.S. Government Series’ investment in the U.S. Government Master Portfolio reflects its proportionate interest in the net assets of the U.S. Government Master Portfolio.

As the Money Market Feeder Funds and Cadre Reserve Fund - U.S. Government Series invest all of their investable assets in the Money Market Master Portfolio and U.S. Government Master Portfolio, respectively, the Schedule of Investments for the Money Market Feeder Funds and Cadre Reserve Fund - U.S. Government Series have been excluded from this filing. The Schedule of Investments of the Money Market Master Portfolio and U.S. Government Master Portfolio as of December 31, 2007

are as follows:
