SUN LIFE (N.Y.) VARIABLE ACCOUNT A
NOTES TO FINANCIAL STATEMENTS
(1) ORGANIZATION
Sun Life (N.Y.) Variable Account A (the "Variable Account"), a separate
account of Sun Life Insurance and Annuity Company of New York (the
"Sponsor"), a wholly owned subsidiary of Sun Life Assurance Company of
Canada (U.S.), was established on December 3, 1984 as a funding vehicle
for individual variable annuities. 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 is invested in shares of a specific mutual fund selected by
contract owners from among available mutual funds (the "Funds") advised
by Massachusetts Financial Services Company ("MFS"), an affiliate of the
Sponsor.
(2) SIGNIFICANT ACCOUNTING POLICIES
GENERAL
The preparation of financial statements in conformity with generally
accepted accounting principles requires 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 revenues and expenses
during the reporting period. Actual results could differ from those
estimates.
INVESTMENT VALUATIONS
Investments in the Funds are recorded at their net asset value. Realized
gains and losses on sales of shares of the Funds are determined on the
identified cost basis. Dividend income and capital gain distributions
received by the Sub-Accounts are reinvested in additional Fund shares and
are recognized on the ex-dividend date.
Exchanges between Sub-Accounts requested by contract owners 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 subject to tax.
<PAGE>
(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
deduction is at an effective annual rate of 1.3%.
Each year on the contract anniversary, a contract maintenance charge
("Account Fee") of $30 is deducted from each contract's accumulation
account to cover administrative expenses relating to the contract. After
the annuity commencement date, the Account Fee is deducted pro rata from
each annuity payment made during the year.
The Sponsor does not deduct a sales charge from purchase payments.
However, a withdrawal charge (contingent deferred sales charge) may be
deducted to cover certain expenses relating to the sale of the contract.
In no event shall the aggregate withdrawal charges exceed 5% of the
purchase payments made under the contract.

INDEPENDENT AUDITORS' REPORT
To the Contract Owners participating in Sun Life (N.Y.) Variable Account A
and the Board of Directors of Sun Life Insurance and Annuity Company of New
York:
We have audited the accompanying statement of condition of Sun Life (N.Y.)
Variable Account A (the "Variable Account") as of December 31, 1998, the
related statement of operations for the year then ended, and the statements
of changes in net assets for the years ended December 31, 1998 and 1997.
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 as of December 31,
1998 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 Variable Account as of December 31,
1998, the results of its operations and the changes in its net assets for the
respective stated periods in conformity with generally accepted accounting
principles.
