BlackRock — Passive Treasury
With respect to the portion of the Fund allocated to BlackRock’s Passive Treasury Strategy, BlackRock will invest primarily in U.S. Treasuries and government agency bonds while seeking to replicate overall risk characteristics of a specific index. BlackRock utilizes a stratified sampling approach that involves investing in a representative sample of securities that collectively has an investment profile similar to that of the underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security’s price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index.
The first paragraph under the “Risk/Return Summary — Management — Sub-Advisers” section of the Prospectus and Summary Prospectus is hereby deleted and replaced with the following:
The Adviser allocates Fund assets for each investment strategy to Sub-Advisers, which allocations may be adjusted or eliminated at any time. Insight, PIMCO and BlackRock are the current Sub-Advisers to the Fund.
