OF
KEYPORT LIFE INSURANCE COMPANY
SUPPLEMENT DATED JANUARY 13, 1999 TO
PROSPECTUS DATED MAY 1, 1998
- --------------------------------------------------------------------------
The second paragraph in the "Keyport and the Variable Account" section on
page 7 of the prospectus is changed to read:
Keyport writes individual life insurance and individual and group annuity
contracts on a non-participating basis. Keyport is licensed to do business
in all states except New York and is also licensed in the District of
Columbia and the Virgin Islands. Keyport has been rated A (Excellent) by
A.M. Best and Company, independent analysts of the insurance industry.
Standard & Poor's ("S&P") has rated Keyport AA for excellent financial
security, Moody's has rated Keyport A2 for good financial strength and Duff
& Phelps has rated Keyport AA- for very high claims paying ability. The
Best's A rating is in the second highest rating category, which also
includes a lower rating of A-. S&P and Duff & Phelps have one rating
category above AA and Moody's has two rating categories above A. Within the
S&P AA category, only AA+ is higher. The Moody's "2" modifier signifies
that Keyport is in the middle of the A category while the Duff & Phelps "-"
modifier signifies that Keyport is at the lower end of the AA category.
These ratings merely reflect the opinion of the rating company as to the
relative financial strength of Keyport and Keyport's ability to meet its
contractual obligations to its policyholders. Even though assets in the
Variable Account are held separately from Keyport's other assets, ratings
of Keyport may still be relevant to Certificate Owners since not all of
Keyport's contractual obligations relate to payments based on those
segregated assets (e.g., see "Death Provisions" for Keyport's obligation
after certain deaths to increase the Certificate Value if it is less than
the guaranteed minimum death benefit amount).
