Item 1.

Security and Issuer

This Schedule 13D/A constitutes the first amendment to the Schedule 13D originally filed by the Reporting Persons with the Securities and Exchange Commission on March 9, 2007 (the “Statement”) with respect to the common stock, $.10 par value (the “Shares”), of Unum Group, a Delaware corporation (the “Issuer” or the “Company”). Except as specifically amended by this Schedule 13D/A, the Statement remains in full force and effect.

Item 3.	Source and Amount of Funds or Other Consideration
Item 3 of the Statement is hereby amended and restated as follows: RILLC and the Managed Accounts purchased an aggregate of 3,302,624 Shares for a total consideration (including brokerage commissions) of $67.5 million derived from capital of the Managed Accounts and margin borrowings from certain client margin accounts at Credit Suisse Securities (USA) LLC (“CSSU”).
The Relational LPs purchased an aggregate of 22,359,702 Shares for total consideration (including brokerage commissions) of $459.8 million derived from the capital of the Relational LPs and margin borrowings from CSSU for RFP, RCP, RH1 and RH2.
Interest on the margin debt balance of the margin accounts described above is charged at the then Federal Funds Rate plus 50 basis points. CSSU has a lien on the Shares held by certain Managed Accounts and those held by RFP, RCP, RH1 and RH2 to secure repayment of the margin borrowings described above.

Item 5.

Interest in Securities of the Issuer

Item 5 of the Statement is hereby amended and restated as follows:

(a) As of the date of this Statement, the Reporting Persons beneficially owned in the aggregate 25,662,326 Shares, constituting 7.49% of the outstanding Shares. The percentage of Shares owned being based upon 342,656,811 Shares outstanding on February 23, 2007, as set forth in the Issuer’s Annual Report on Form 10-K for the year ended December 31, 2006. The Reporting Persons may be deemed to have direct beneficial ownership of the Shares as follows:

NAME	NUMBER OF SHARES	% OF OUTSTANDING SHARES		VOTING AND DISPOSITIVE POWER
RILLC	3,302,624	0.96	%	Sole
RILP	4,191,241	1.22	%	Sole
RFP	111,682	0.03	%	Sole
RCP	249,937	0.07	%	Sole
RP	95,793	0.03	%	Sole
RH1	2,378,780	0.69	%	Sole
RH2	2,181,084	0.64	%	Sole
RH4	623,740	0.18	%	Sole
RH6	411,417	0.12	%	Sole
RH7	197,768	0.06	%	Sole
RI III	127,757	0.04	%	Sole
RI VIII	4,049,405	1.18	%	Sole
RI IX	1,722,937	0.50	%	Sole
RI X	3,180,597	0.93	%	Sole
RI XI	1,730,549	0.51	%	Sole
RI XV	619,149	0.18	%	Sole
RI XVI	487,866	0.14	%	Sole

RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 3,302,624 Shares that are owned by it and the Managed Accounts. Additionally, RILLC, as the sole general partner, or sole managing member of the general partner, of each of Relational LPs may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) the 22,359,702 Shares beneficially owned by the Relational LPs because the limited partnership agreements of the Relational LPs specify that RILLC has sole investment discretion and voting authority with respect to those Shares.

Each of Messrs. Whitworth and Batchelder, as Principals of RILLC, may be deemed to share indirect beneficial ownership of the Shares which RILLC may beneficially own. Each of Messrs. Whitworth and Batchelder disclaims beneficial ownership of such Shares for all other purposes.

To the best of the knowledge of each of the Reporting Persons, other than as set forth above, none of the persons named in Item 2 is the beneficial owner of any Shares.

(b) See item (a) above.
(c) Information concerning transactions in the Shares by the Reporting Persons during the past 60 days and not previously reported is set forth in Exhibit A filed with this Statement.
(d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares covered by this Statement, except that dividends from, and proceeds from the sale of, the Shares held by accounts managed by RILLC may be delivered to such accounts.
(e) Not applicable.

Item 7.	Material to Be Filed as Exhibits
	The following Exhibits are filed herewith: Exhibit A – Information concerning transactions in the Shares affected by the Reporting Persons since the last filing.

Signature

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
