investment objective. A proxy statement describing these proposals in detail

be to achieve a high level of current income, consistent with the preservation
of capital and maintenance of liquidity.

investment policies. These changes do not require shareholder approval. The
Fund's amended investment policies would reposition the Fund as an
"intermediate" term government fund. The Fund proposes to invest at least 65%
of its assets in U.S. Government securities, including mortgage backed
securities issued by U.S. Government agencies, Tennessee Valley Authority and
World Bank obligations and medium term notes. Under normal market conditions,
the Fund would maintain a weighted average maturity or average life of three
to ten years.
