Opinion by Judge PREGERSON; Dissent by Judge NORRIS.

The Hughes Salaried Retirees Action Committee (the “Committee”) and three individual participants in the Hughes Non-Bargaining Retirement Plan (the “Plan”) [collectively the “Retirees”] brought an action under § 502 of the Employment Retirement Income Security Act of 1974 (“ERISA”), 29 U.S.C. § 1132 , against the Plan administrator (the Administration). The Retirees alleged that the Administrator breached his fiduciary duties and violated ERISA disclosure requirements when he refused to provide them with a list of the names and addresses of Plan participants. The district court dismissed the Retirees’ complaint for failure to state a claim and denied the Administrator’s request for attorneys’ fees. We have jurisdiction under 28 U.S.C. § 1291 . We affirm in part and reverse and remand in part.

BACKGROUND

The Committee was formed for the purpose of communicating with Plan participants and beneficiaries about their rights under the Plan and Hughes Aircraft’s failure to use surplus Plan assets to increase benefits. In April 1990, the Committee wrote to the Administrator to request a list of Plan participants’ names and addresses. By letter, the Administrator denied the request. 1

*1005 The Retirees then filed an action under ERISA for breach of fiduciary duty and enforcement of their right to disclosure of the names and addresses of Plan participants. The Retirees want to use the list to inform Plan participants and beneficiaries about Hughes’ allegedly improper use of the Plan’s approximately $1 billion in surplus assets, 2 and to gain support for future efforts to negotiate with Hughes or litigate to create increased Plan benefits using the surplus assets. The Retirees also intend to use the list to form a watchdog committee to assure that the Plan is properly managed. The Retirees contend that, under these circumstances, the Administrator’s refusal to supply the names and addresses amounted to a breach of his fiduciary duty of care, ERISA § 404(a)(1)(A); violated the requirement that an administrator provide participants and beneficiaries with certain plan documents, ERISA § 104(b)(4); and violated the Administrator’s fiduciary duty to manage the Plan in accordance with its terms, ERISA § 404(a)(1)(D).

In December 1992, the Administrator moved to dismiss the Retirees’ amended complaint for failure to state a claim upon which relief can be granted, Fed.R.Civ.P. 12(b)(6). The district court granted the Administrator’s motion. The Retirees timely appeal. 3

ANALYSIS

We review de novo the district court’s dismissal of the Retirees’ complaint under Fed.R.Civ.P. 12(b)(6). Oscar v. University Students Co-operative Ass’n, 965 F.2d 783, 785 (9th Cir.) (en banc), cert. denied, — U.S. -, 113 S.Ct. 655 , 121 L.Ed.2d 581 (1992).

I. Non-Disclosure as Violation of ERISA § 404(a)(1)(A)

The Retirees allege that the Administrator’s refusal to provide the requested fist of names and addresses violated ERISA § 404(a)(1)(A), 29 U.S.C. § 1104 (a)(1)(A). That section provides that the Administrator, as fiduciary to the Plan, 4 must discharge his duties of plan administration “solely in the interest of the participants and beneficiaries and — (A) for the exclusive purpose of: (i) providing benefits to participants and their beneficiaries; and (ii) defraying reasonable expenses of administering the plan....” ERISA § 404(a)(1)(A), 29 U.S.C. § 1104 (a)(1)(A). 5

We interpret the fiduciary duties under ERISA by “ ‘bearing in mind the special nature and purposes of employee benefit plans intended to be effectuated by [ERISA].’” Acosta v. Pacific Enterprises, 950 F.2d 611, 618 (9th Cir.1991) (quoting H.R.Rep. No. 533, 93d Cong., 2nd Sess. (1973), reprinted in 1974 U.S.C.C.A.N. 4639, 4650). The fiduciary duties help ensure that employee plan participants and beneficiaries are equipped to safeguard their rights.

1974 U.S.C.C.A.N. at 4649 (emphasis added); United States v. Sarault, 840 F.2d 1479,1484 (9th Cir.1988) (Congress enacted ERISA to enable retirees to police their own plans and receive the information needed to do so). Therefore, based on ERISA § 404(a), the Administrator’s disclosure duty “may in some circumstances extend to additional disclosures [beyond the requirements of ERISA §§ 101-11, 29 U.S.C. §§ 1021-31 ] where the interests of the beneficiaries so require.” Acosta, 950 F.2d at 618 (emphasis added).

The Administrator’s disclosure duty based on ERISA § 404(a) derives from common law trust duties of a fiduciary. Id. A fiduciary’s common law duties include a duty to furnish to each beneficiary all information that she needs to enforce her rights under the trust. Restatement (Second) of Trusts § 173. A trust beneficiary is entitled to a list of the names of beneficiaries so that she can communicate with them for mutual aid and protection. This right of a trust beneficiary to know the identity of fellow beneficiaries creates a duty in the trustee to provide the information upon demand. See George Gleason Bogert, 46 The Law of Trusts and Trustees, Rev. 2nd Ed. § 961, p. 8 (1978).

ERISA § 404(a) incorporates the common law trust duties regarding disclosure “to the extent that they relate to the provision of benefits or the defrayment of expenses, and only insofar as they do not contradict or supplant the existing reporting and disclosure provisions.” Acosta, 950 F.2d at 618 . 6 In this case, as in Acosta , we focus on the. relationship of a disclosure duty “to the provision of benefits.” In Acosta , a plan participant demanded a list of plan participant names, addresses, and shareholdings, to solicit votes for an election of corporate directors. We found no fiduciary disclosure duty because there was an insufficient nexus between the provision of benefits and the request. “The term ‘benefit’ refers to a participant’s or beneficiary’s right to receive monies from the plan administrator ..., not the right to vote in an election for corporate officers.” Id. See also In re Sears, Roebuck and Co. Secs. Litig., 792 F.Supp. 977, 983-84 (E.D.Pa.1992) (following Acosta , and finding no fiduciary duty to pay costs of mailing a board candidate’s proxy statement to plan participants).

In Acosta , we did not hold that plan participants may never obtain a list of participants’ names and addresses; we held only that the solicitation of votes for corporate directors is not related to the provision of plan benefits. The present case is distinguishable from the vote solicitation in Acosta .

The Retirees requested the participant list for two purposes: (1) to communicate with other Plan participants and beneficiaries about increasing benefits from the Plan’s surplus funds; and (2) to create a watchdog committee to ensure that the Administrator properly manages the Plan. Both of these purposes relate to the Administrator’s duty to provide benefits: The Retirees’ underlying purpose in both instances is to ensure that Plan participants are receiving and continue to receive benefits to which they are entitled under the Plan, including increased benefits from the Plan’s surplus assets. Access to the list could help the Retirees to secure what they perceive to be their rights under the Plan. This connection between the requested list and the “provision of benefits” satisfies our test in Acosta . Therefore, the Administrator had a fiduciary duty to disclose the list.

The district court incorrectly concluded otherwise because it focused on *1007 the information the list provides rather than the Retirees’ purpose for seeking it. (District Court Order at 6) (“[0]ther plan participants have no information about the payment of benefits, while the Administrator does. [The Retirees] do not, then, seek information about the provision of bene-fits_”). Acosta requires us to focus on the Retirees’ purpose for seeking the list. See Acosta, 950 F.2d at 619 . Only the Retirees’ purpose for wanting the list, not the list itself, must relate to the provision of benefits. Under Acosta , the Administrator had a fiduciary duty to disclose the list. The district court erred in concluding otherwise. 7

By this opinion, we do not imply that administrators have a fiduciary duty to disclose a list of plan participant names and addresses as a matter of course in every case. The fiduciary disclosure duty applies only when, as in this case, a plan participant or beneficiary intends to use the demanded list to enforce her rights under an ERISA plan or to monitor the administrator’s management of plan assets in accordance with ERISA requirements. Communicating with fellow Plan participants for these purposes “relates to the provision of benefits.” Were we to deny reasonable demands by plan participants and beneficiaries for information that can aid them in enforcing their rights to ERISA-protected benefits, we would ignore congressional intent, discussed supra, to arm employees with sufficient information to protect their interests. Therefore, we reverse dismissal of the Retirees’ claim under § 404(a)(1)(A).

II. Non-Disclosure as Violation of ERISA § 104(b)(4)

As a second cause of action, the Retirees allege that the Administrator’s failure to supply the Plan participant list violated the disclosure requirement of ERISA § 104(b)(4), 29 U.S.C. § 1024 (b)(4). That section provides:

ERISA § 104(b)(4), 29 U.S.C. § 1024 (b)(4) (emphasis added). The Retirees argue that the requested list of participant names and addresses is one of the “other instruments under which the plan is ... operated,” id., because the list is essential to operating the Plan.

We agree with the Retirees and hold that a mailing list of plan participants (or beneficiaries) is an “instrument[] under which [a] plan is ... operated” within the meaning of ERISA § 104(b)(4). The mailing list is critical to the operation of a plan because without it an administrator could not possibly pay benefits or keep plan participants informed of plan administration. Compare Werner v. Morgan Equip. Co., 15 Employee Benefits Cas. 2295 , 1992 WL 453355 , at *6 (N.D.Cal. 1992) (valuation reports are within ERISA § 104(b)(4) because they are used to “carry out” the determination of benefits, which is “a regular, required and necessary function of the operation of the [plan]”) and Lee v. Dayton Power and Light Co., 604 F.Supp. *1008 987, 1002 (S.D.Ohio 1985) (a manual containing charts essential to the calculation of benefits is an “underlying plan document” and therefore, an instrument under which the plan is established or operated) with Cham-bless v. Masters, Mates & Pilots Pension Plan, 571 F.Supp. 1480, 1456-57 (S.D.N.Y.1983) (minutes of trustee meetings and decisions are not within ERISA § 104(b)(4)).

The Administrator urges us to limit the broad statutory language: “instruments under which the plan is established or operated.” In much the same vein, the district court, in dismissing the Retirees’ claim, explained that ERISA § 104(b)(4) limits the universe of “other instruments” to those documents that are similar to documents specifically listed in that section. The district court stated that § 104(b)(4) requires the Administrator to disclose only those documents that describe the terms and conditions of the Plan or its administration and financial status. The court contrasted such documents with the mailing list that the Retirees seek because the list would provide the Retirees with no information about the Plan. The language of § 104(b)(4), however, contains no such limitation, and we have found no other authority for limiting the statutory language this way. 8 Therefore, we reverse the dismissal of the Retirees’ claim under § 104(b)(4).

III. Violation of the Plan’s Terms as Fiduciary Breach

The Retirees’ third claim is that the Administrator breached his fiduciary duty under ERISA § 404(a)(1)(D) 9 by violating Art. V § 5.1(g) of the Plan, which authorizes the Administrator to impose a reasonable charge to cover the cost of furnishing documents to participants and beneficiaries upon their written request pursuant to ERISA § 104(b)(4). We affirm the district *1009 court’s dismissal of this claim. The Administrator did not violate the Plan provision that allows him to charge the Retirees for copies of documents because he has not yet disclosed the documents. Nor do we see how this provision creates any substantive rights for the Retirees. 10

IV. Attorneys’ Fees on Appeal

The Retirees seek attorneys’ fees on appeal under ERISA § 502(g)(1), 29 U.S.C. § 1132 (g)(1). ERISA § 502(g)(1) provides, in relevant part: “In any action under this subchapter ... by a participant, beneficiary, or fiduciary, the court in its discretion may allow a reasonable attorney’s fee and costs of action to either party.” To determine whether to award attorneys’ fees under ERISA § 502(g)(1) a court should consider:

Franklin v. Thornton, 983 F.2d 939, 943 (9th Cir.1993) (quoting Hummell v. S.E. Rykoff & Co., 634 F.2d 446, 453 (9th Cir.1980)). The Retirees sought to resolve a significant legal question regarding ERISA, they sought to benefit all Plan participants, and their position is meritorious. For these reasons, we grant their request for attorneys’ fees on appeal.

AFFIRMED in part; REVERSED AND REMANDED in part.

. Because this is an appeal from a dismissal tinder Fed.R.Civ.P. 12(b)(6), we accept the facts *1005 alleged in the complaint as trae. Love v. United States, 915 F.2d 1242, 1245 (9th Cir.1989).

. A related appeal, Jacobson v. Hughes Aircraft Co., No. 93-55392, concerns the merits of Hughes' alleged improper use of surplus assets.

. The Retirees filed notice of appeal on March 1, 1993. We reject the Administrator’s contention that this appeal is untimely because it was filed more than 30 days from the district court's entry of the Civil Minutes on January 20, 1993. In fact, the appeal is timely because the notice of appeal was filed within 30 days of the entry of judgment on February 10, 1993. See Fed. R.App.P. 4(a)(1) ("In a civil case in which an appeal is permitted by law as of right from a district court to a court of appeals the notice of appeal required by Rule 3 shall be filed with the clerk of the district court within 30 days after the date of entry of the judgment or order appealed from_"); Vernon v. Heckler, 811 F.2d 1274, 1276 (9th Cir.1987) (explaining that until the judgment is set forth on a separate document, the period for filing notice of appeal is tolled).

. The Administrator does not challenge the Retirees' allegation that he was a fiduciary to the Plan.

. The Retirees also allege that the Administrator violated ERISA § 404(a)(1)(B), 29 U.S.C. § 1104 (a)(1)(B), which requires a fiduciary to discharge the duties of plan administration "with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims...." We do not address this claim because neither the district court’s order nor the parties' briefs address it.

. The Administrator concedes that a disclosure duty covering the participant mailing list would not contradict or supplant the existing ERISA reporting and disclosure provisions.

. The district court also based its ruling on its finding that the Retirees' amended complaint alleged no facts that would establish an entitlement to the Plan's surplus assets. (District Court Order at 6). The court concluded that the Retirees “have no right to force the Administrator to disclose information about [surplus assets] to which they are not entitled.” Id. For purposes of this appeal, we need not address the merits of the Retirees’ claim to the surplus Plan assets. We note, however, that plan participants and beneficiaries are not required to establish an entitlement to specific benefits in order to trigger the fiduciary disclosure duly. Plan participants and beneficiaries are entitled to receive mailing lists (assuming the Acosta test is met) without establishing a right to unpaid benefits.

At the stage where disclosure is sought, the merits of the lawsuit have simply not been sufficiently well developed to permit the district court to determine whether or not the requesters have established that they are entitled to additional benefits. However, so long as the requesters have established the requisite nexus between disclosure and the claim to provision of additional benefits, the Administrator’s disclosure duties are triggered.

. The Administrator refers us to Metropolitan Life Ins. Co. v. Massachusetts, 471 U.S. 724, 740 , 105 S.Ct. 2380, 2389 , 85 L.Ed.2d 728 (1985), which cautions that construction of ERISA provisions "must begin with the language employed by Congress and the assumption that the ordinary meaning of that language accurately expresses the legislative purpose” (internal quotations omitted).

Metropolitan Life, however, does not support the Administrator's position. The language of the statute does not contain the limitation the Administrator urges us to adopt, and the legislative history of ERISA § 104(b)(4) simply confirms that the plain meaning of the statute is the meaning which Congress intended. The relevant history indicates that Congress created the ERISA § 104(b)(4) disclosure requirements to improve the quality of information participants receive about operation of their plan, and thus enable them to better police the plan. The Committee on Labor and Public Welfare explained as follows:

S.Rep. No. 127, 93rd Cong., 2d Sess. (1973), reprinted in 1974 U.S.C.C.A.N. 4838, 4863 (emphasis added).

. ERISA § 404(a)(1)(D) provides as follows:

29 U.S.C. § 1104 (a)(1)(D).

. The Retirees also allege that the Administrator breached his fiduciary duty by violating Article V § 5.2 of the Plan. That section states that the "Plan shall be administered, interpreted and applied fairly and equitably and in accordance with the specified purpose of the Plan.” We read the Retirees' failure to address Article V § 5.2 on appeal to mean that they do not appeal the district court's dismissal of this claim.
