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.

                                                                              21

NOTES TO FINANCIAL STATEMENTS -- continued
(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 contracts, 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 contracts, 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
contracts, 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.

To the Participants in Regatta, Regatta Gold, Regatta Classic and Regatta

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, Emerging Markets Equity Sub-Account, International Growth
Sub-Account, International Growth and Income Sub-Account, Government Securities

Governments Sub-Account, Global Growth Sub-Account, Global Total Return
Sub-Account, and Strategic Growth Sub-Account of Sun Life of Canada (U.S.)
Variable Account F (the "Sub-Accounts") as of December 31, 1999, the related
statement of operations for the years then ended and the statements of changes
in net assets for the years ended December 31, 1999 and 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 December 31, 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 December 31, 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.
