v.

WillScot Mobile Mini Holdings Corporation, et al., Defendants. A plan administrator does not breach the duty of prudence by exercising discretion permitted by the plan and the Employee Retirement Income Security Act. Before the Court is the Defendant’s Motion to Dismiss Plaintiff’s Amended Complaint under Federal Rule of Civil Procedure 12(b)(6). (Doc. 29.) The Motion is fully briefed. (Docs. 30, 31.) The Court will grant the Motion. The following facts are taken from the Amended Complaint. (Doc. 26.) The Court accepts these allegations as true for this motion to dismiss. Cousins v. Lockyer, 568 F.3d 1063, 1067 (9th Cir. 2009). WillScot is an employer that sponsors and administers a defined contribution retirement plan for its employees (the “Plan”). (Doc. 26 ¶¶ 8, 16.) The Plan incurs administrative expenses for services such as recordkeeping, accounting, and legal services. (Id. ¶ 73.) Participants fund the Plan through payroll deductions, and WillScot provides matching contributions. (Id. ¶ 75.) Plan participants are immediately vested into their own contributions and any earnings from their contributions. (Id. ¶ 81.) Participants become fully vested in the WillScot matching contributions after a long enough tenure with WillScot, which typically ranges from four to six years. (See id.) If a Plan participant terminates employment with WillScot before becoming fully vested, the participant forfeits the matching contributions and any earnings from those contributions. (Id. ¶ 82.) Under the terms of the Plan, the plan administrator has discretion to use these forfeitures to pay for administrative expenses or reduce WillScot’s future matching contribution obligations. (Id. ¶¶ 83-84.) Specifically, as alleged in the Complaint, the Plan document states, Any forfeitures occurring during a Plan Year may be used to pay administrative expenses under the Plan at any time, if so directed by the Administrator. . . . [A]ny forfeitures not used to pay administrative expenses under the Plan shall be applied to reduce the contributions of the Employer for the immediately following Plan Year . . . . (Id. ¶ 83.) Plaintiff Ariel Armenta commenced this action because WillScot “consistently used Forfeited Plan Assets to almost exclusively reduce WillScot’s contractually obligated contributions to the Plan and not to defray Administrative Expenses.” (Id. ¶ 87.) Armenta’s original Complaint contained five causes of action. (Doc. 1 at 15-21.) The Court dismissed four of these counts with prejudice and dismissed one with leave to amend. (Doc. 25 at 11.) For the surviving count, the Court noted that Armenta’s Amended Complaint must “allege facts for the Court ‘to reasonably infer from the circumstantial factual allegations that the fiduciary’s decision-making process was flawed.’” (Id. (quoting Terraza v. Safeway Inc., 241 F. Supp. 3d 1057, 1070 (N.D. Cal. 2017)).). A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which relief can be granted “tests the legal sufficiency of a claim.” Navarro v. Block, 250 F.3d 729, 732 (9th Cir. 2001). A court may dismiss a complaint “if there is a lack of a cognizable legal theory or the absence of sufficient facts alleged under a cognizable legal theory.” Conservation Force v. Salazar, 646 F.3d 1240, 1242 (9th Cir. 2011) (citation modified). A complaint must assert sufficient factual allegations that, when taken as true, “state a claim to relief that is plausible on its face.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (citation omitted). Plausibility is more than a mere possibility; a plaintiff is required to provide “more than labels and conclusions, and a formulaic recitation of the elements of a cause of action will not do.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007). When analyzing the sufficiency of a complaint, the well-pled factual allegations are taken as true and construed in the light most favorable to the plaintiff. Cousins, 568 F.3d at 1067. Armenta’s only remaining claim is a breach of the duty of prudence under the Employee Retirement Income Security Act (“ERISA”). (Doc. 26 at 28-30.) In her Amended Complaint, Armenta was required to allege facts showing that the fiduciary’s decision-making process was flawed. (Doc. 25 at 11.) ERISA governs the administration of employee benefit plans and protects the interests of plan participants and their beneficiaries with uniform guidelines and rules. Metro. Life Ins. Co. v. Parker, 436 F.3d 1109, 1111 (9th Cir. 2006). “The two most basic components of any ERISA plan are the plan administrator and the plan documents.” Id. Under ERISA, plan administrators are fiduciaries who have a duty to act “with the care, skill, prudence, and diligence” of a “prudent man.” 29 U.S.C. § 1104(a)(1)(B). In fulfilling this duty, a fiduciary must act for the exclusive purpose of “providing benefits to participants and their beneficiaries” and “defraying reasonable expenses of administering the plan.” Id. § 1104(a)(1)(A). Fiduciaries must act “in accordance with the documents and instruments governing the plan insofar as such documents and instruments are consistent with” ERISA. Id. § 1104(a)(1)(D). This duty is not “an exclusive duty to maximize pecuniary benefits.” Sievert v. Knight-Swift Transp. Holdings, Inc., 780 F. Supp. 3d 870, 877 (D. Ariz. 2025) (quoting Wright v. Or. Metallurgical Corp., 360 F.3d 1090, 1100 (9th Cir. 2004)). Rather, “the fiduciary duty is fulfilled where the fiduciary ensures that participants have received their promised benefits.” Hutchins v. HP Inc., 767 F. Supp. 3d 912, 924 (N.D. Cal. 2025). Ultimately, “the prudence analysis focuses on a fiduciary’s conduct in arriving at an investment decision, not on its results.” Terraza, 241 F. Supp. 3d at 1069 (citation modified). Armenta has alleged no new facts to plausibly allege that the plan administrator’s decision-making process was flawed in violation of the duty of prudence. Instead, she revives failed arguments from the first motion to dismiss: that the decision-making process was flawed because (1) the administrator should have first used the funds to defray administrative expenses, and (2) a conflict of interest plagued the process. A. Use of Forfeited Assets First, Armenta alleges that a prudent administrator would ensure “that Forfeited Plan Assets would be used first to defray plan expenses prior to being used to reduce employer contributions.” (See Doc. 26 ¶¶ 62, 116.) Then, to show a breach of the duty of prudence, Armenta’s Complaint lists how the plan administrator used forfeited assets to offset employer contributions prior to defraying administrative expenses each year. (See id. ¶¶ 87-114.) The Plan, however, gives the plan administrator discretion to use forfeited funds to reduce administrative expenses or reduce WillScot’s matching contributions. (Id. ¶¶ 83-84.) It does not require that the funds be used in a particular order. Moreover, ERISA permits plan administrators to use forfeited funds to offset the employer’s matching contributions.
