1. Foreign securities for the Loomis Sayles High Yield Bond Portfolio: The
following is added as the last sentence under "About the Loomis Sayles High
Yield Bond Portfolio--Principal investment strategies" on page 6 of the

made to the information included under "Appendix A to Prospectus--Portfolio
Manager Prior Performance":
A. Delete reference to Neuberger Berman Partners Mid Cap Value Portfolio
in the first sentence of the first paragraph on page 32 of the Prospectus.
B. Change the second to the last word to "three" rather than "four" in
the second sentence of the first paragraph on page 32 of the Prospectus to
reflect that portfolio manager prior performance is available with respect
to the portfolio managers of three of the Portfolios.

Prospectus to add Neuberger Berman Partners Mid Cap Value Portfolio to the
list of Portfolios for which no similar account performance information is

Prospectus.
3. Typographical errors: Item 20 in the table under "Appendix B to

number "13" under "A" in the "Portfolios" column and by changing the reference
under "C" from Portfolio number "14" to Portfolio number "7."
