This Schedule 13D/A constitutes the fifth amendment to the Schedule 13D originally filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on March 9, 2007 (the “Statement”) and amended by Amendment No. 1, No. 2 No. 3 and No. 4 filed by the Reporting Persons with the SEC on March 30, 2007, May 30, 2007, July 26, 2007 and May 14, 2009(the “Amendments”) 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 hold an aggregate of 4,817,501 Shares for a total consideration (including brokerage commissions) of $88.5 million derived from capital of the Managed Accounts.
The Relational LPs hold an aggregate of 12,729,384 Shares for total consideration (including brokerage commissions) of $279.2 million derived from the capital of the Relational LPs and margin borrowings from CSSU for RFP, RCP, RH1, RI XX and RI XXIII.
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, RI XX and RI XXIII 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 17,546,885 Shares, constituting 5.30% of the outstanding Shares. The percentage of Shares owned being based upon 331,274,343 Shares outstanding on April 28, 2009, as set forth in the Issuer’s Form 10-Q for the quarter ended March 31, 2009. 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	4,817,501	1.45	%	Sole
RILP	2,896,719	0.87	%	Sole
RFP	65,961	0.02	%	Sole
RCP	140,522	0.04	%	Sole
RP	71,885	0.02	%	Sole
RH1	1,387,772	0.42	%	Sole
RH4	533,686	0.16	%	Sole
RH6	685,391	0.21	%	Sole
RI III	38,611	0.01	%	Sole
RI VIII	2,618,205	0.79	%	Sole
RI IX	807,350	0.24	%	Sole
RI X	915,898	0.28	%	Sole
RI XV	372,600	0.11	%	Sole
RI XVI	272,938	0.08	%	Sole
RI XX	274,206	0.08	%	Sole
RI XXII	577,123	0.17	%	Sole
RI XXIII	325,436	0.10	%	Sole
RIA 1	745,081	0.22	%	Sole

RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 4,817,501 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 12,729,384 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.
