PART I

This Post-Effective Amendment to the Registration Statement on Form S-6 (File No. 333-65048), which became effective on September 15, 2001 (the "Registration Statement"), is being filed pursuant to Rule 485(b) under the Securities Exchange Act of 1933, as amended, to supplement the prospectus in the Registration Statement. The supplement included in this Amendment describes additional investment options to be made available under the flexible premium variable life insurance policies offered pursuant to the Registration Statement. This Amendment relates only to the supplement to the prospectus and does not delete, amend or supersede any information contained in the Registration Statement, as amended.

SUPPLEMENT DATED JULY 15, 2002

TO

PROSPECTUS DATED MAY 1, 2002

FOR

FUTURITY CORPORATE VARIABLE UNIVERSAL LIFE INSURANCE

ISSUED BY SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)

SUN LIFE OF CANADA (U.S.) VARIABLE ACCOUNT G

This supplement contains information on two new investment options available as Sub-Accounts under the Futurity Corporate Variable Universal Life Insurance Policies. Deutsche Asset Management, Inc. serves as investment adviser of the new investment options.

I. The third bullet on page 1 is changed to read: "The Variable Account is divided into 61 Sub-Accounts, each of which invests exclusively in shares of a corresponding mutual fund."

II. Footnote 2 of The Underlying Fund Annual Expenses (1) Table on pages 5-7 is changed to read:

(2) All expense figures are shown after expense reimbursements or waivers, except for the bracketed figures which show what the expense figures would have been absent reimbursement. All expense figures are based on actual expenses for the fiscal year ended December 31, 2002, except that the expense figures shown for Scudder VIT EAFE® Equity Index Fund, Scudder VIT Small Cap Index Fund, SC^SM Alger Growth Fund, SC^SM Alger Income & Growth Fund, SC^SM Alger Small Capitalization Fund and Sun Capital All Cap Fund^SM are estimates for the year 2002. No actual expense figures are shown for these funds because the Scudder Funds commenced operations on April 30, 2002 and the others commenced operations in either April or May of 2002. Therefore, these Funds have less than 10 months of investment experience.

III. The Underlying Fund Annual Expenses (1) Table on pages 5-7 is amended by the addition of the following:

	Management Fees (After Reimbursement)	Other Expenses (After Reimbursement)(2)	12b-1 or Other Service Fees	Total Fund Annual Expenses (After Reimbursement)(2)
Scudder VIT EAFE® Equity Index Fund(18)	0.45%	0.20%	0.25%	0.90%[1.05%]
Scudder VIT Small Cap Index Fund(18)	0.35%	0.10%	0.25%	0.70%[0.88%]

(18) The investment advisor, Deutsche Asset Management, Inc. has voluntarily agreed to waive a portion of its management fee and reimburse certain expenses. These waivers and reimbursements may be discontinued at any time.

IV. The first sentence of the sixth paragraph of The Variable Account section of page 8 is changed to read: "The Variable Account is divided into 61 Sub-Accounts."

V. The first sentence of the third margin paragraph on page 8 is changed to read: "The Variable Account has 61 Sub-Accounts."

VI. The first sentence of the first paragraph of The Funds section of page 8 is changed to read: "The Policy currently offers 61 mutual fund options, which are briefly described below."

VII. The Funds section beginning on page 8 is amended by the addition of the following:

Scudder VIT Funds (advised by Deutsche Asset Management, Inc.)

Scudder VIT EAFE® Equity Index Fund seeks to replicate, as closely as possible, before expenses, the performance of the Morgan Stanley Capital International (MSCI) EAFE Index (EAFE Index), which emphasizes stocks of companies in major markets in Europe, Australasia and the Far East.

Scudder VIT Small Cap Index Fund seeks to replicate, as closely as possible, before expenses, the performance of the Russell 2000 Small Stock Index (the Russell 2000 Index), which emphasizes stocks of small U.S. companies.

THIS SUPPLEMENT SHOULD BE READ AND RETAINED FOR FUTURE REFERENCE.

PART II

UNDERTAKING TO FILE REPORTS

Subject to the terms and conditions of Section 15(d) of the Securities Exchange Act of 1934, the undersigned Registrant hereby undertakes to file with the Securities and Exchange Commission such supplementary and periodic information, documents, and reports as may be prescribed by any rule or regulation of the Commission heretofore or hereafter duly adopted pursuant to authority conferred in that section.

REPRESENTATION OF REASONABLENESS OF FEES

Sun Life Assurance Company of Canada (U.S.)("Sun Life of Canada (U.S.)") hereby represents that the aggregate fees and charges under the Policy are reasonable in relation to the services rendered, the expenses expected to be incurred, and the risks assumed by Sun Life (U.S.).

UNDERTAKING ON INDEMNIFICATION

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the depositor pursuant to its certificate of incorporation, bylaws, or otherwise, the depositor has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the depositor of expenses incurred or paid by a director, officer or controlling person of the depositor in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the depositor will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the act and will be governed by the final adjudication of such issue.

The supplement consisting of 2 pages.
