Murphy R. Godwin alleges that Sun Life Assurance Company of Canada (“Sun Life”) violated the Employee Retirement Income Security Act of 1974 (“ERISA”) 1 by (a) failing to provide plan information that Godwin had requested; (b) illegally offsetting his award under the plan with Social Security old age benefits; and (c) erroneously calculating an offset for workers’ compensation benefits. The district court granted Sun Life’s motion for summary judgment. Godwin appeals, and, finding no error, we affirm.
I
Godwin began work for School Pictures, Inc., in 1966. In the mid-1970s, Godwin became a participant in a group long-term disability plan issued to School Pictures by Sun Life. Subsequent to his participation, the plan was amended five times, the last amendment taking effect in December 1983. On December 19, 1984,- Godwin sustained an injury in the course of his employment. He continued to work, however, until November 4, 1986, when a second *325 employment-related injury left him disabled. On November 18, 1986, School Pictures terminated Godwin — then sixty-seven years old — for health reasons. After he was terminated, Godwin applied to Sun Life for benefits under the plan.
Sun Life determined that Godwin was entitled to fifteen months of benefits (eighteen months less a three-month waiting period), and it issued Godwin two checks for a total of $1,773.11. Those checks represented three months of benefits at $591.04 a month. 2 However, Sun Life later recalculated the benefits to which Godwin was entitled, included an offset of $725 a month for social security benefits, and determined that the offsets exceeded benefits. 3 Subsequently, the Mississippi Workers’ Compensation Commission approved Godwin’s workers’ compensation claims with regard to his two on-the-job injuries. After deducting attorneys fees and expenses, Godwin received $9,941.62. 4
In July 1989, Godwin brought suit in district court against Sun Life, claiming that Sun Life’s actions violated ERISA. The parties filed cross-motions for summary judgment, and the district court granted Sun Life’s motion. Godwin appeals.
II
Godwin contends (a) that he is entitled to statutory penalties under ERISA because Sun Life failed to provide plan information that Godwin requested; (b) that Sun Life’s offset of social security old age benefits was illegal because the offset was not set forth in the original policy and Godwin never received notice that the plan was amended to include the offset; and (c) that *326 Sun Life erroneously calculated an offset for workers’ compensation benefits.
A
Godwin contends that he is entitled to penalties due to Sun Life’s failure to supply certain requested information. Godwin alleges that, in July 1985 — prior to his application for disability benefits — he requested from Sun Life information relating to the benefit plan and that, over the course of the next four years, Sun Life and School Pictures refused his requests. Godwin argues that Sun Life’s failure to provide the information violates ERISA.
Section 502(c)(1) of ERISA provides, in relevant part, that:
Any administrator who ... fails or refuses to comply with a request for any information which such administrator is required by this subchapter to furnish to a participant or beneficiary (unless such failure or refusal results from matters reasonably beyond the control of the administrator) by mailing the material requested to the last known address of the requesting participant or beneficiary within 30 days after such request may in the court’s discretion be personally liable to such participant or beneficiary in the amount of up to $100 a day from the date of such failure or refusal and the court may in its discretion order such relief as it deems proper.
29 U.S.C. § 1132(c). The term administrator is defined as:
(i) the person specifically so designated by the terms of the instrument under which the plan is operated;
(ii) if an administrator is not so designated, the plan sponsor....
29 U.S.C. § 1002(16)(A).
The district court’s summary judgment against Godwin was based, in part, on its conclusion that, because no administrator was named in the policy, School Pictures was the sponsor and, therefore, the administrator, pursuant to 29 U.S.C. § 1002(16)(A). The district court thus found that an action under 29 U.S.C. § 1132 did not exist against Sun Life. See Record on Appeal, vol. 2, at 444-45. The district court also discounted Godwin’s argument that Sun Life was a de facto administrator of the plan. The district court concluded that Godwin was not prejudiced by the alleged failure to disclose information, and that the question whether Sun Life was a de facto administrator thus was irrelevant. 5
Godwin asks us to recognize Sun Life as a de facto administrator and argues that ERISA does not require a claimant to show prejudice in order to be entitled to penalties.
6
In support of this argument, Godwin reminds us of our decision in
Fisher v. Metropolitan Life Ins. Co.,
In Fisher, the plaintiff suggested that the plan insurer, Metropolitan, should be regarded as a de facto plan administrator because Metropolitan had been delegated responsibility for evaluating and adminis *327 tering claims. Noting that “Fisher’s argument that Metropolitan should be regarded as a de facto administrator has intuitive appeal[,]” 7 we nevertheless declined to recognize Metropolitan as the de facto administrator because, in any event, we found no abuse of discretion on the part of the district court in refusing to award the plaintiff penalties under section 1132(c).
As in
Fisher,
we need not here resolve the question whether Sun Life should be regarded as a. de facto administrator, thus entitling Godwin to penalties under 29 U.S.C. § 1132.
See Paris v. Profit Sharing Plan For Employees of Howard B. Wolf, Inc.,
B
Godwin next contends that the 1981 amendment to the Sun Life plan which mandates an offset for “any amount of Old Age Income provided to the employee under the Social Security Act” 9 does not apply to him because he had no notice of the amendment when he applied for benefits.
We begin with the premise that, as a general rule, Social Security old age income may be offset against monthly disability payments.
See Alessi v. Raybestos-Manhattan, Inc.,
ERISA requires that participants and beneficiaries be furnished with a summary plan description. See 29 U.S.C. § 1022. This summary plan description must contain certain information, including “circumstances which may result in disqualification, ineligibility, or denial or loss of benefits” 29 U.S.C. § 1022(b). Sections 102(a)(1) and 104(b)(1) of ERISA require that a copy of the summary plan description and all modifications and changes be furnished to participants and beneficiaries not later than 210 days after the plan year in which the change is adopted. See 29 U.S.C. §§ 1022(a)(1) and 1024(b)(1), amendment noted in 29 U.S.C.A. § 1024(b)(1) (Supp.1991).
In support of its assertion that Sun Life gave proper notice of the amendment, Sun Life presented to the district court the affidavit of its Director of Group Services and *328 Administration — Dale L. Kurtz. 11 In his affidavit, Kurtz testified that Sun Life prepared and sent to School Pictures for distribution updated summary plan description booklets following each amendment to the School Pictures plan. 12 Godwin, however, maintains that he never received notice of the amendment, and he argues that such personal notice was required under ERISA.
The district court, in rejecting Godwin's argument that the 1981 amendment was invalid as to him for lack of notice, relied principally on two cases interpreting the ERISA notification provisions:
Moore v. Metropolitan Life Ins. Co.,
Wherever fault might lie for the alleged nonreceipt by Godwin of notice of the [Í981] amendment, the amendment to the employee welfare benefit plan at issue is valid even in the absence of his knowledge of its existence. Henne [], 660 F.Supp at 1474-75 (amendment valid though its adoption' was never noticed by employer); see also Moore,856 F.2d at 491-92 (employer could alter benefit plan where summary plan descriptions unambiguously reserved the right to change or discontinue welfare benefit plan)! That is because when benefit plans may by their terms be modified at any time and [when] an employer makes no attempt to conceal amendments, an employee cannot seek to avoid application of a valid amendment by claiming he never received notice of its adoption. Henne,660 F.Supp. at 1475 .
Record on Appeal, vol. 2, at 449-50. The district court found, in the alternative, that Godwin was not prejudiced by his lack of knowledge of the amendment. Id.
' We agree with the district court that an amendment to a welfare benefit plan is valid despite a beneficiary’s lack of personal notice, unless the beneficiary can show active concealment of the amendment,
Blau v. Del Monte Corp.,
*329 c
Godwin’s final argument is that the offset for workers’ compensation benefits was calculated incorrectly. The exclusion clause in question provides, in relevant part:
The Monthly Indemnity of an employee at any date will be the amount of the employee’s insurance at such date, less the sum of the following amounts:
:je jje * sje }¡{ >¡c
(5) any indemnity provided for the employee under any Workmen’s Compensation law or similar legislation.
Record on Appeal, vol. 2, at 264. At the time Godwin’s disability payments became payable under the policy, Godwin’s workers’ compensation claim was controverted. Because Godwin was not then receiving workers’ compensation benefits, Sun Life relied upon reference manuals setting forth the maximum weekly amount of workers’ compensation available in Mississippi and determined that $576 should be offset monthly. 16
Godwin does not dispute Sun Life’s authority to offset benefits with workers’ compensation payments. But he does challenge Sun Life’s calculation of the workers’ compensation offset, reasoning that the payment for the worker’s compensation settlements occurred after Godwin’s benefit period and that his lump sum workers’ compensation settlements also included payment for items that had nothing to do with his disability. 17 Godwin suggests that the settlement payments should have been prorated over 450 weeks. Sun Life, on the other hand, contends that Godwin’s entire settlement award should be applied as an offset.
The validity of workers’ compensation offsets is well-established.
Alessi v. Raybestos-Manhattan, Inc.,
The district court, in allowing an offset for the entire amount of the workers’ compensation award rather than a prorated amount, noted that the Sun Life plan mandated an offset for “any” workers’ compensation award. Record on Appeal, vol. 2, at 453. As noted supra, the precise words of the exclusion clause provide that “any indemnity provided for the employee under any Workmen’s Compensation law or similar legislation” may be offset. We find these words to be clear and unambiguous: “any indemnity” means “any indemnity”.
Godwin cites two cases as supporting the proposition that only a prorated portion of the workers’ compensation should have been
offset
— Martin
v. McCarthy,
Martin
likewise is inapplicable to the case sub judice. In
Martin,
a district court found 1) that the trustees of an ERISA-regulated pension plan properly withheld pension benefits pending the settlement of a workers’ compensation claim; and 2) that the trustees of the plan properly refused to pay pension benefits once the workers’ compensation claim was settled and the amount of the workers’ compensation benefits exceeded the amount of the pension benefits.
Martin,
We conclude, therefore, that Sun Life was entitled to reduce Godwin’s disability benefits by the entire amount he received due to workers’ compensation.

For the foregoing reasons, we AFFIRM.
Notes
. 29 U.S.C. § 1001 et seq. (1988).
.With respect to Godwin’s application for benefits, Sun Life issued one check for $1,182.07, representing pay period 1 March 87 to 30 April 87 and a second check for $591.04. The amounts of these checks were calculated as follows:
1st check March 1987 Gross Monthly Benefit $1,188.95
Less Workers Comp. Offset —estimated 576.00
612.95
April 1987 Gross Monthly Benefit $1,188.95
Less Workers Comp. Offset —estimated 576.00
612.95
Less FICA Tax 43.83
$1,182.07
2nd Check May 1987 Gross Monthly Benefit $1,188.95
Less Workers Comp. Offset —estimated 576.00
Less FICA tax 21.91
$591.04
.Sun Life arrived at the new figures under a 1981 amendment to the plan that offset "any amount of Old Age Income provided to the employee under the Social Security Act.” Sun Life determined that, pursuant to the policy (as amended), Godwin was entitled to receive, during his fifteen-month period, $1188.95 monthly, less a $576 monthly workers’ compensation offset and a $725 offset representing Godwin's monthly payment from the Social Security Administration. These calculations result in a negative $112.05; however, the plan provides for a minimum monthly benefit of $50.
.The gross amount for both claims was $15,-000. The settlement of Godwin’s claims were general in nature, citing, among other things, payment for disability, loss of wage-earning capacity, penalties, interest, and all medical expenses which Godwin might incur in the future or which may have been incurred in the past.
. Record on Appeal, vol. 2, at 446:
,[E]ven if Sun life is a plan fiduciary and had a duty to provide Godwin the information he requested, Godwin has not demonstrated that any prejudice to his right to benefits resulted from a failure by Sun Life to provide the requested information.
. Godwin cites
Curry v. Contract Fabricators Inc. Profit Sharing Plan,
In exercising its discretion, therefore, the trial court may undoubtedly consider whether a denial of information prejudiced a plaintiff, but prejudice is not a prerequisite to an award of civil penalties.
Curry,
.
Fisher,
. The express statutory language does not require a demonstration of prejudice. See 29 U.S.C. § 1132(c).
. See supra note 3.
. The amendment procedure, in general, was proper. Written amendments were authorized under the plan if agreed to by a representative of the company. See Record on Appeal, vol. 2, at 249. Sun Life presented to the district court the affidavit of its Senior Claims Officer — J. Neville Meehan — who testified that the 1981 amendment was approved in writing by A. Don Goss — Vice President of Finance for School Pictures. See Record on Appeal, vol. 2, at 235.
. Record on Appeal, vol. 2, at 283-86.
. Record on Appeal, vol. 2, at 285:
Employees of School Pictures, Inc. were notified of the terms and conditions of the School Pictures LTD plan by means of summary plan description booklets ("SPD’s") which were composed by Sun Life according to instructions received from School Pictures, Inc. regarding desired changes in coverage. The SPD’s were printed in Massachusetts and then forwarded to School Pictures’ home office in Jackson, Mississippi, for distribution to covered employees. This same procedure was followed on each occasion when the School Pictures LTD plan was amended.
.
But see Hozier v. Midwest Fasteners, Inc.
. Indeed, not only was Godwin not prejudiced by the 1981 amendment, he benefitted from it. Under the unamended plan, Godwin would not have been eligible for any benefits when he became disabled at sixty-seven because benefits were terminated at age sixty-five. Thus the amendment that Godwin complains of was the same amendment which made him eligible for any benefits at all.
. As the Third Circuit noted in
Hozier v. Midwest Fasteners, Inc.,
. This amount was the maximum monthly benefit allowed by state law for the injury of December 19, 1984. The total disability payment was $126 per week, for 450 weeks, or $56,700 in total. See Miss.Code Ann. § 71-3-17 (1972).
. For example — penalties, interest, and medical benefits.
