Supplement to the Statement of Additional Information dated May 1, 1995
The following information replaces Limitation #1 in the section captioned
"Additional Information About Investment Limitations and Policies" on page
2 of the Statement of Additional Information. The Investment Grade
Portfolio may not:
"1. Borrow money, except for temporary purposes in an aggregate
amount not to exceed 5% of the value of its total assets at the time of
borrowing;"
The following information replaces the section captioned "Reverse
Repurchase Agreements" on page 11 of the Statement of Additional
Information:
"Reverse Repurchase Agreements and Other Borrowing A reverse
repurchase agreement is a portfolio management technique in which a
Portfolio temporarily transfers the possession of a portfolio instrument
to another person, such as a financial institution or broker-dealer, in
return for cash. At the same time, the Portfolio agrees to repurchase the
instrument at an agreed upon time (normally within seven days) and price,
including interest payment. The Investment Grade Portfolio may also enter
into dollar rolls, in which the Portfolio sells a fixed income security
for delivery in the current month and simultaneously contracts to
repurchase a substantially similar security (same type, coupon and
maturity) on a specified future date. During the roll period, the
Portfolio would forgo principal and interest paid on such securities. The
Portfolio would be compensated by the difference between the current sales
price and the forward price for the future purchase, as well as by any
interest earned on the proceeds of the initial sale. A Portfolio may
engage in reverse repurchase agreements and dollar rolls (with respect to
the Investment Grade Portfolio) as a means of raising cash to satisfy
redemption requests or for other temporary or emergency purposes without
the necessity of selling portfolio securities.
When a Portfolio reinvests the proceeds of a reverse repurchase
agreement in other securities, any fluctuations in the market value of
either the securities transferred to another party or the securities in
which the proceeds are invested would affect the market value of the
Portfolio's assets. As a result, such transactions could increase
fluctuation in the Portfolio's net asset value. If a Portfolio reinvests
the proceeds of the agreement at a rate lower than the cost of the
agreement, engaging in the agreement will lower the Portfolio's yield.
While engaging in reverse repurchase agreements and dollar rolls (with
respect to the Investment Grade Portfolio), each Portfolio will maintain
cash, U.S. government securities or other high-grade, liquid debt
securities in a segregated account at its custodian bank with a value at
least equal to the Portfolio's obligation under the agreements.
The ability of each Portfolio to engage in reverse repurchase
agreements and dollar rolls (with respect to the Investment Grade
Portfolio) is subject to each Portfolio's fundamental investment
limitation concerning borrowing, i.e., that borrowing may be for temporary
purposes only and in an amount not to exceed 5% of the Portfolio's total
assets."
