UNIFORM PRUDENT INVESTOR ACT PREFATORY NOTE

Over the quarter century from the late 1960's the investment practices of fiduciaries experienced significant change. The Uniform Prudent Investor Act (UPIA) undertakes to update trust investment law in recognition of the alterations that have occurred in investment practice. These changes have occurred under the influence of a large and broadly accepted body of empirical and theoretical knowledge about the behavior of capital markets, often described as "modern portfolio theory."
