FUTURITY FOCUS
VARIABLE AND FIXED ANNUITY
ISSUED BY SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)
THE FOLLOWING LANGUAGE APPLIES ONLY TO CONTRACTS ISSUED TO OR HELD BY
PARTICIPANTS RESIDENT OR DOMICILED IN PUERTO RICO:
Section 6, Taxes, of the Profile is hereby deleted with respect to
Contracts issued in Puerto Rico and is hereby replaced by the following:
"Under the tax laws of Puerto Rico, when an annuity payment is
made under your Contract, your Annuitant or any other Payee is
required to include as gross income the portion of each annuity
payment equal to 3% of the aggregate purchase payments you made under
the Contract. The amount if any, in excess of the included amount is
excluded from gross income. After an amount equal to the aggregate
amount excluded from gross income has been received, all of the
annuity payments are considered to be taxable income. You should
consult with your tax adviser for specific tax information."
The section of the Prospectus entitled "Federal Tax Status" is hereby
amended by the addition of the following sub-section:
"PUERTO RICO TAX CONSIDERATIONS ON VARIABLE ANNUITY CONTRACTS
The Contract offered by this Prospectus is considered an annuity
contract under Section 1022 of the Puerto Rico Internal Revenue Code
of 1994, as amended (the "1994 Code"). Under the current provisions of
the 1994 Code, no income tax is payable on increases in value of
accumulation shares of annuity units credited to a variable annuity
contract until payments are made to the annuitant or other payee under
such contract.
If any annuity distributions are made under an annuity contract,
the annuitant or other payee will be required to include as gross
income the portion of each payment equal to 3% of the aggregate
premiums or other consideration paid for the annuity. The amount, if
any, in excess of the included amount is excluded from gross income.
After an amount equal to the aggregate amount excluded from gross
income has been received, all of the annuity payments are considered
to be taxable income.
In the event payment under a Contract is made in a lump sum, the
amount of the payment would be included in the gross income of the
Annuitant or other Payee to the extent of the Annuitant's aggregate
premiums or other consideration paid.
The provisions of the 1994 Code with respect to qualified
retirement plans described in this Prospectus vary significantly from
those under the Internal Revenue Code. Although we
<PAGE>
currently offer the Contract in Puerto Rico in connection with
qualified retirement plans, the text of this Prospectus under the
heading "Federal Tax Status" dealing with such qualified retirement
plans is inapplicable to Puerto Rico and should be disregarded.
For information regarding the income tax consequences of owning a
Contract, you should consult a qualified tax adviser."
THIS SUPPLEMENT IS NOT VALID UNLESS ACCOMPANIED OR PRECEDED BY THE CURRENT
PROSPECTUS OF FUTURITY FOCUS VARIABLE AND FIXED ANNUITY, DATED MAY 1, 1999, AND
THE CURRENT PROSPECTUSES OF THE FUNDS. THIS SUPPLEMENT AND THE PROSPECTUSES
