REGATTA, REGATTA GOLD, REGATTA CLASSIC AND REGATTA PLATINUM SUB-ACCOUNTS
INCLUDED IN SUN LIFE OF CANADA (U.S.) VARIABLE ACCOUNT F

NOTES TO FINANCIAL STATEMENTS

(1) ORGANIZATION
Sun Life of Canada (U.S.) Variable Account F (the "Variable Account"), a
separate account of Sun Life Assurance Company of Canada (U.S.), (the
"Sponsor"), was established on July 13, 1989 as a funding vehicle for the
variable portion of Regatta contracts, Regatta Gold contracts, Regatta Classic
contracts, Regatta Platinum contracts (collectively, the "Contracts") and
certain other fixed and variable annuity contracts issued by the Sponsor. The
Variable Account is registered with the Securities and Exchange Commission under
the Investment Company Act of 1940 as a unit investment trust.

The assets of the Variable Account are divided into Sub-Accounts. Each
Sub-Account attributable to the Contracts is invested in shares of a specific
corresponding series of MFS/Sun Life Series Trust (the "Series Trust"), an
open-end management investment company registered under the Investment Company
Act of 1940. Massachusetts Financial Services Company ("MFS"), an affiliate of
the Sponsor, is the investment adviser to the Series Trust.

(2) SIGNIFICANT ACCOUNTING POLICIES
GENERAL
The preparation of financial statements in conformity with generally accepted
accounting principles requires the Sponsor's management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

INVESTMENT VALUATIONS
Investments in shares of the Series Trust are recorded at their net asset value.
Realized gains and losses on sales of shares of the Series Trust are determined
on the identified cost basis. Dividend income and capital gain distributions
received by the Sub-Accounts are reinvested in additional Series Trust shares
and are recognized on the ex-dividend date.

Exchanges between Sub-Accounts requested by participants under the Contracts are
recorded in the new Sub-Account upon receipt of the redemption proceeds.

FEDERAL INCOME TAX STATUS
The operations of the Variable Account are part of the operations of the Sponsor
and are not taxed separately. The Variable Account is not taxed as a regulated
investment company. The Sponsor qualifies for the federal income tax treatment
granted to life insurance companies under Subchapter L of the Internal Revenue
Code. Under existing federal income tax law, investment income and capital gains
earned by the Variable Account on contract owner reserves are not taxable and,
therefore, no provision has been made for federal income taxes.

(3) CONTRACT CHARGES
A mortality and expense risk charge based on the value of the Variable Account
is deducted from the Variable Account at the end of each valuation period for
the mortality and expense risks assumed by the Sponsor. The deductions are
transferred periodically to the Sponsor. Currently, the deduction is at an
effective annual rate of 1.25% for Regatta, Regatta Gold and Regatta Platinum
contracts and 1.00% for Regatta Classic contracts.

Each year on the account anniversary, an account administration fee ("Account
Fee") equal to the lesser of $30 or 2% of the participant's account value in the
case of Regatta and Regatta Gold contracts, $35 in the case of Regatta Platinum
contracts and $50 in the case of Regatta Classic contracts (after account year
5, the account fee, for Regatta Gold and Regatta Platinum, may be changed
annually, but it may not exceed the lesser of $50 or 2% of the participant's
account value) is deducted from the participant's account to reimburse the
Sponsor for certain administrative expenses. After the annuity commencement
date, the Account Fee will be deducted pro rata from each variable annuity
payment made during the year.

The Sponsor does not deduct a sales charge from purchase payments. However, in
the case of Regatta, Regatta Gold and Regatta Platinum, a withdrawal charge
(contingent deferred sales charge) of up to 6% of certain amounts withdrawn,
when applicable, may be deducted to cover certain expenses relating to the sale
of the contracts and certificates. In the case of Regatta Classic, a withdrawal
charge of 1% is applied to purchase payments withdrawn which have been credited
to a participant's account for less than one year.

For assuming the risk that withdrawal charges may be insufficient to compensate
it for the costs of distributing the Regatta contracts, the Sponsor makes a
deduction from the Variable Account at the end of each valuation period for the
first seven account years at an effective annual rate of 0.15% of the net assets
attributable to such contracts. No deduction for the distribution expense charge
is made after the seventh account anniversary.

As reimbursement for administrative expenses attributable to Regatta Gold,
Regatta Classic and Regatta Platinum contracts, which exceed the revenues
received from the Account Fees described above derived from such contracts, the
Sponsor makes a deduction from the Variable Account at the end of each valuation
period at an effective annual rate of 0.15% of the net assets attributable to
such contracts.

(4) ANNUITY RESERVES
Annuity reserves are calculated using the 1983 Individual Annuitant Mortality
Table and an assumed interest rate of at least 4% or 3%, as stated in each
participant's contract or certificate, as applicable. Required adjustments to
the reserves are accomplished by transfers to or from the Sponsor.

                                                                              21

INDEPENDENT AUDITORS' REPORT

To the Participants in Regatta, Regatta Gold, Regatta Classic and Regatta
 Platinum Sub-Accounts and the Board of Directors of Sun Life Assurance Company
of Canada (U.S.):

We have audited the accompanying statement of condition of Bond Sub-Account,
Capital Appreciation Sub-Account, Capital Opportunities Sub-Account,
Massachusetts Investors Trust Sub-Account, Emerging Growth Sub-Account, Equity
Income Sub-Account, MFS/Foreign & Colonial Emerging Markets Equity Sub-Account,
International Growth Sub-Account, International Growth and Income Sub-Account,
Government Securities Sub-Account, High Yield Sub-Account, Managed Sectors
Sub-Account, Massachusetts Investors Growth Stock Sub-Account, Money Market
Sub-Account, New Discovery Sub-Account, Research Sub-Account, Research Growth
and Income Sub-Account, Research International Sub-Account, Strategic Income
Sub-Account, Total Return Sub-Account, Utilities Sub-Account, Global Asset
Allocation Sub-Account, Global Governments Sub-Account, Global Growth
Sub-Account, and Global Total Return Sub-Account of Sun Life of Canada (U.S.)
Variable Account F (the "Sub-Accounts") as of June 30, 1999, the related
statement of operations for the period then ended and the statements of changes
in net assets for the six month period ended June 30, 1999 and the year ended
December 31, 1998. These financial statements are the responsibility of
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities held at June 30, 1999 by correspondence with the
custodian. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Sub-Accounts as of June 30, 1999, the
results of their operations and the changes in their net assets for the
respective stated periods in conformity with generally accepted accounting
principles.
