LYNCH, Circuit Judge.
The question in this case is whether, under the Employee Retirement Income Security Act of 1974 (ERISA), 29 U.S.C. §§ 1001-1461, non-union retirees of NSTAR Electric & Gas Corporation (“NSTAR”) were entitled to vested lifetime dental benefits which could not be changed by NSTAR, under the terms of one of two early retirement programs (“ERPs”), one in 1997 and one in 1999. The district court granted summary judgment to NSTAR on the plaintiffs’ claims under ERISA. We affirm.
I.
Much of the relevant background is detailed in the companion case,
Senior v. NSTAR Electric & Gas Corp.,
449 F.3d 206, 208-215, No. 05-2015, slip op. at 4-20 (1st Cir. May 31, 2006). That case involved the question of whether certain labor agreements which allowed the retirees to take advantage of the same ERPs at issue here gave former union employees an entitlement to vested lifetime dental benefits which could not be modified by the company.
Id.
at 207, 2006 WL 1479797. In
Senior,
we focused on interpretation of the labor agreements under § 301 of the Labor Management and Relations Act (LMRA), 29 U.S.C. § 185.
Id.
at 216, 2006 WL 1479797. In this case, by contrast, there are no labor agreements to be analyzed under § 301 of the LMRA; only ERISA claims are raised.
Well before the establishment of the ERPs, the company had provided non-union retirees with dental benefits. The summary plan descriptions (SPDs) for the dental plan both before and after the establishment of the ERPs, reserved the right of the company to “amend, modify or terminate the Plan at any time” and did not vest dental benefits. These SPDs were part of the dental plan documents. The plaintiffs all received copies of these SPDs at the time they took advantage of the ERPs.
The ERPs were described in program brochures distributed to the plaintiffs. For plaintiffs retiring under the 1997 Personnel Reduction Program (“1997 PRP”), the brochure stated two points of importance to the ease:
Health and Dental Insurance Coverage:
Employees who were at least age forty (40) and had completed at least twelve (12) full years of System service as of January 1, 1993 and currently meet the “Rule of 75”[
] will be entitled to medical and dental insurance coverage providing they pay ten percent (10%) of the
current medical and dental premium until age sixty two (62). At age 62 the
Company will pay 100% of the premium. The 1997 PRP brochure at the same time made those dental benefits subject to the ERISA dental plan documents:
This summary is not intended to offer detailed descriptions of the System’s employee benefit plans. All information furnished is governed by the provisions of the actual plan documents pertaining to the appropriate benefit plans. If any conflict arises between this summary and the System’s employee benefit plan documents, or if any point is not covered, the terms of the appropriate plan documents will govern in all cases.
Thus, the 1997 PRP brochure referred employees to plan documents, which themselves contained a reservation of the company’s right to alter the benefits.
As to the 1999 Voluntary Severance Program (“1999 VSP”), a brochure distributed to non-union employees stated generally that for “those employees who are eligible for post-retirement ... benefits,” “[Coverage will continue to employee and eligible dependents.” That brochure provided no further details regarding the retirement dental plan coverage. Importantly, it did contain a similar reference to the plan documents, as had the 1997 PRP brochure, stating that “the appropriate plan documents ... will govern in all cases.” In addition, the 1999 brochure contained its own explicit reservation of rights to the company:
The Company reserves the right to change and terminate coverage for current and former employees at any time. Any such change may be in the benefits provided, the contributions required, or in any other aspect in accordance with applicable laws.
Thus, the 1999 VSP brochure both referred to the plan documents and contained its own reservation of rights by the company.
Each of the plaintiffs took advantage of one or the other of the two ERPs, and received individualized retirement benefits summaries. The plaintiffs’ case relies on two categories of evidence which contained no language about the company’s reservation of rights. As to dental benefits, the summaries provided the exact same terms for all plaintiffs, regardless of which ERP they took advantage of: ‘Tour dental coverage will be for your life. Your spouse and/or eligible dependents will be covered for 12 months after your death.” The summaries did not include an express statement reserving the company’s right to alter the plan, but did contain a reference to the plan documents, which themselves contained the reservation:
This summary is not intended to offer detailed descriptions of employee benefit plan. All information furnished is governed by the provisions of the actual plan documents pertaining to the appropriate benefit plans. If any conflict arises between this summary and the System’s employee benefit plan documents, or if any point is not covered, the terms of the appropriate plan will govern in all cases.
The plaintiffs do not claim that company representatives orally promised that the benefits were vested, or that they could not be modified or terminated by the company; they do argue that the company representatives omitted the fact that retirement dental benefits could be modified or terminated by the company at any time.
In December 2002, the company notified the plaintiffs and other employees who had participated in the ERPs that their dental benefits would cease once they reached age 65, if they had not already reached that age by April 1, 2003.
The plaintiffs filed suit on May 25, 2004. They alleged that the company had violated ERISA by violating the terms of the ERPs, in that the dental benefits were vested and so could not be discontinued until the death of the retiree. In the alternative, they alleged that if the ERPs did not provide for vested lifetime dental benefits, the company was in breach of its obligation as an ERISA fiduciary to “discharge [its] duties with respect to a plan solely in the interest of the participants and beneficiaries,” 29 U.S.C. § 1104(a)(1), by having misrepresented to them, at the time they were considering the ERPs, that the benefits were vested.
On May 31, 2005, the district court granted the company’s motion for summary judgment in its entirety. The court relied entirely on the reasoning from its decision rejecting the union retirees’ ERISA claims for vested retirement benefits under the ERPs,
see Senior v. NSTAR Elec. & Gas Corp.,
372 F.Supp.2d 159, 166-68 (D.Mass.2005), which had issued that same day.
The district court stated that there was a “strong presumption against the automatic vesting of welfare benefits” and that a promise to vest “is not to be inferred lightly.”
Id.
at 165. It noted that the plaintiffs could only point to the individualized benefits summaries and program brochures to support their claim for vested retirement dental benefits.
Id.
at 166-67. The district court rejected the plaintiffs’ claims that the welfare benefits were vested and unchangeable, “refus[ing] to infer a vesting requirement based on personalized documents that plainly state they are not governing” and that “explicitly direct prospective retirees to consult the ‘actual plan’ documents, which, in turn, properly reserve for the [company] the right ‘to amend, modify or terminate the Plan at any time.’ ”
Id.
at 167.
The district court also rejected the plaintiffs’ claims of breach of fiduciary duty, finding no evidence that the company intended to mislead the retirees about the scope of the benefits.
Id.
at 167-68. It noted that the statement regarding “lifetime” benefits was contained not in a governing plan document, but in individualized benefits summaries which were not governing.
Id.
at 168. The district court also noted the company’s position that, at the time of the ERPs, the company had thought it would be able to provide lifetime benefits, but had continued to reserve its right to “amend, modify, or terminate the Plan at any time” should future conditions change.
Id.
The court found this position “consistent with the documentation.”
Id.
On appeal, the plaintiffs challenge the district court’s conclusion that the 1997 and 1999 ERPs did not provide vested lifetime dental benefits. In the alternative, they argue that the company was in breach of its fiduciary duties under ERISA by having misrepresented the plan benefits when the plaintiffs were considering whether to take advantage of the ERPs.
II.
We first dispose of an issue about the governing law. The company argues that the ERPs are not themselves ERISA benefit plans, and therefore the plaintiffs’ claims are not cognizable under ERISA.
See Senior,
372 F.Supp.2d at 166 n. 6 (rejecting the argument). The company relies on our opinion in
O’Connor v. Commonwealth Gas Co.,
251 F.3d 262 (1st Cir.2001), a case involving one of the same retirement programs (the 1997 PRP). The company is wrong in its premises and in its analysis. Whether the ERPs themselves constitute ERISA plans, or whether they concern preexisting ERISA welfare benefits, is beside the point. The plain
tiffs’ claims are about dental benefits under an ERISA plan and ERISA.
The plaintiff retirees in
O’Connor,
two former non-union employees of Commonwealth Gas, had retired just before the implementation of the 1997 PRP.
Id.
at 265. They brought suit “claiming that material misrepresentations made by agents of [the company] misled them into retiring before the effective date of the [1997 PRP]” in breach of the company’s fiduciary duties under ERISA.
Id.
At issue were the significant severance benefits that were offered to those taking advantage of the 1997 PRP, not the dental benefits at issue here.
Id.
We noted that those severance benefits “fit[ ] comfortably within the category of benefits we have deemed not subject to ERISA coverage because of their limited non-discretionary nature.”
Id.
at 268. We found that, to the extent the 1997 PRP increased other benefits that may have implicated ERISA, those changes were “little more than afterthoughts to the severance bonus” and thus insufficient to move the plaintiffs’ misrepresentation claims into the realm of ERISA.
Id.
By contrast, the retirement dental benefits at issue here are undoubtedly ERISA welfare benefits.
See
29 U.S.C. § 1002(1) (defining welfare benefit plans as plans that provide “medical, surgical, or hospital care or benefits, .or benefits in the event of sickness, accident, disability, death or unemployment”). Provision of these dental benefits requires the sort of “continuing administrative and financial obligations by the employer to the behoof of employees or their beneficiaries” that the Supreme Court has required before finding the existence of an ERISA plan.
Belanger v. Wyman-Gordon Co.,
71 F.3d 451, 454 (1st Cir.1995) (citing
Fort Halifax Packing Co. v. Coyne,
482 U.S. 1, 12, 107 S.Ct. 2211, 96 L.Ed.2d 1 (1987);
Dist. of Columbia v. Greater Wash. Bd. of Trade,
506 U.S. 125, 130 n. 2, 113 S.Ct. 580, 121 L.Ed.2d 513 (1992)). These dental benefits had been provided by the company to retirees for a number of years prior to the ERPs, under terms provided by the dental plan documents.
That the aspect of the ERPs at issue in
O’Connor,
the severance payment, was found to be not enforceable under ERISA does not make the retirement dental benefits at issue here similarly unenforceable under ERISA. “[I]n dealing with a multifaceted ... early retirement Program, some facets may be governed by ERISA ..., while others may be governed by state law.... If a facet is governed by ERISA, any dispute over the terms
of that benefit
must be resolved by looking to ERISA’s statutory provisions and relevant case law.”
Stearns v. NCR Corp.,
297 F.3d 706, 710 (8th Cir.2002).
We turn to the plaintiffs’ claims under ERISA.
III.
We review the district court’s entry of summary judgment de novo, drawing all reasonable inferences in favor of the plaintiffs as the non-moving party.
Fenton v. John Hancock Mut. Life Ins. Co.,
400 F.3d 83, 87 (1st Cir.2005). Summary judgment is appropriate if there is no genuine dispute as to material facts and the moving party is entitled to judgment as a matter of law.
Id.
We may affirm on any ground supported by the record.
Mulvihill v. Top-Flite Golf Co.,
335 F.3d 15, 19 (1st Cir.2003). Further, the parties agree that the company’s interpretation of the plan is subject to de novo review under ERISA.
A.
Violation of the Terms of the ERISA Welfare Benefit Plan
ERISA draws a distinction between welfare benefit plans and pension
benefit plans. Unlike pension benefit plans, which are subject to strict vesting requirements, welfare benefits are not automatically vested under ERISA. “ERISA does not create any substantive entitlement to ... welfare benefits,” and “[ejmployers or other plan sponsors are generally free under ERISA, for any reason at any time, to adopt, modify, or terminate welfare plans.”
Curtiss-Wright Corp. v. Schoonejongen,
514 U.S. 73, 78, 115 S.Ct. 1223, 131 L.Ed.2d 94 (1995). As the Supreme Court has noted:
The flexibility an employer enjoys to amend or eliminate its welfare plan is not an accident; Congress recognized that “requir[ing] the vesting of these ancillary benefits would seriously complicate the administration and increase the cost of plans.” Giving employers this flexibility also encourages them to offer more generous benefits at the outset, since they are free to reduce benefits should economic conditions sour. If employers were locked into the plans they initially offered, “they would err initially on the side of omission.”
Inter-Modal Rail Employees Ass’n v. Atchison, Topeka & Santa Fe Ry.,
520 U.S. 510, 515, 117 S.Ct. 1513, 137 L.Ed.2d 763 (1997) (alteration in original) (internal citation omitted) (quoting S.Rep. No. 93-383, at 51 (1973);
Heath v. Varity Corp.,
71 F.3d 256, 258 (7th Cir.1995)).
An employer may “contractually cede[] its freedom” to amend and terminate the plan and may provide retirees with vested retiree welfare benefits that cannot be changed unilaterally.
Id.
An employer may cede this freedom in bilaterally negotiated contracts, like collectively bargained labor agreements,
see Senior,
at -, 2005 WL 1322800, or in the ERISA plan itself,
see Am. Fed’n of Grain Millers v. Int’l Multifoods Corp.,
116 F.3d 976, 980 (2d Cir.1997).
The interpretation of the provisions of an ERISA benefit plan proceeds under federal substantive law, and is guided by “common sense principles of contract interpretation,”
Filiatrault v. Comverse Tech., Inc.,
275 F.3d 131, 135 (1st Cir.2001), although principles from the law of trusts are employed in certain cases,
Allen v. Adage, Inc.,
967 F.2d 695, 698 (1st Cir.1992).
See also Rodriguez-Abreu v. Chase Manhattan Bank, N.A.,
986 F.2d 580, 585 (1st Cir.1993);
Burnham v. Guardian Life Ins. Co.,
873 F.2d 486, 489-90 (1st Cir.1989).
The rules of interpretation of ERISA welfare benefit plans when dealing with unambiguous terms are uncontroversial.
See Grain Millers,
116 F.3d at 980 (citing cases). Under ERISA, unambiguous language in a plan is enforced according to its terms.
See Filiatrault,
275 F.3d at 135;
Burnham,
873 F.2d at 490-91. The question of whether an ERISA plan term is ambiguous is generally a question of law for the judge.
See Allen,
967 F.2d at 698.
It is also the rule that ambiguity in a plan term does not necessarily foreclose summary judgment, as when “the evidence presented about the parties’ intended meaning [is] so one-sided that no reasonable person could decide the contrary.”
Id.
at 698 (quoting
Boston Five Cents Sav. Bank v. Sec’y of Dep’t of HUD,
768 F.2d 5, 8 (1st Cir.1985)).
However, there is substantial disagreement among the courts, and between the parties here, about whether ambiguous plan language may support a finding that a company has promised to vest ERISA welfare plan benefits.
See Grain Millers,
116 F.3d at 980. Under ordinary rules of ERISA plan interpretation, if a party demonstrates ambiguity in a plan on a particular question, reference may be made to
extrinsic evidence to determine the parties’ intended meaning.
See Smart v. Gillette Co. Long-Term Disability Plan,
70 F.3d 173, 178 (1st Cir.1995). If such extrinsic evidence is not one-sided, the issue of the parties’ intent might be for the fact-finder.
Allen,
967 F.2d at 698.
The company argues for a departure from these ordinary rules. It asserts that the intent to vest lifetime welfare benefits that cannot be changed by the company must be found in clear and express language in the ERISA plan documents. In other words, the company argues that if the plan language is ambiguous on the question, there is a presumption that welfare benefits are not vested. The plaintiffs argue that there is no such presumption against the vesting of ERISA welfare benefits.
The circuits have adopted different rules of construction as to vesting of welfare benefits. Such rules may be helpful in particular factual situations but are certainly not a starting point for analysis. We reject the analysis apparently used by the district court,
see Senior,
372 F.Supp.2d at 165, 166-67, that there can never be vesting of retirement welfare benefits unless there is a clear and express statement of such vesting.
Congress’s decision to give employers, in the absence of an affirmative promise to vest welfare benefits, the flexibility to amend and terminate ERISA welfare benefit plans does not mean that ERISA requires a strict rule of construction against vesting of retirement welfare benefits. The company has pointed to nothing else in ERISA or its legislative history to suggest Congress intended these questions to start with such a presumption. Furthermore, the Supreme Court has “analogized ERISA benefit plans to trust agreements and observed that trust agreements are to be construed ‘without deferring to either party’s interpretation.’ ”
Allen,
967 F.2d at 701 (quoting
Bruch,
489 U.S. at 112, 109 S.Ct. 948).
Our case does not involve a special situation. The dental plan documents are express that the company reserves the right to change even promises of lifetime benefits. In that sense, the benefits are not vested. And the 1997 PRP program brochure and the individualized benefits summaries expressly refer to the dental plan documents, which contain those reservations. The 1999 VSP brochure not only refers to those same plan documents, but contains its own express reservation.
The plaintiffs argue that the ERPs, nonetheless, unambiguously vest lifetime retirement dental benefits that cannot be changed. Plaintiffs’ argument is that to give content to the lifetime benefits language in the ERPs, it is necessary to construe the ERPs as creating a new ERISA plan, independent of the continuing ERISA dental plan. That is why, they say, the ERPs do not themselves refer to any specific dental plan. They ask us to focus on the language in the ERP program brochures and the individualized benefit
summaries.
They acknowledge that those documents reference the SPDs, which contain an express reservation of the company’s right to amend the plan. But they argue that the “vague reference ... to the plan documents would not inform the reasonable employee that he or she should review the entirety of several lengthy policies” to determine his or her rights under the dental benefit plans.
The argument fails on several grounds. There is no basis for the plaintiffs’ assertion that the ERPs themselves constitute their own separate ERISA plan. The plaintiffs admit that the brochure and the plan documents do not meet the requirements of an ERISA plan or SPD. They counter by asserting that the “creation of an ERISA plan does not depend on the existence of formal documentation.” But the ERPs themselves refer to existing ERISA plans as providing the more specific terms. The references to the plan documents in the ERP brochures and the individualized plan summaries are prominent. For example, the 1997 PRP brochure states in bold letters that the plan documents are “The Last Word.”
Furthermore, under ERISA, we cannot ignore the SPDs which do contain the reservation, because SPDs play a key role in “communicat[ing] to beneficiaries the essential information about the plan.”
Cur-tiss-Wright,
514 U.S. at 83, 115 S.Ct. 1223. ERISA requires SPDs to be “written in a manner calculated to be understood by the average plan participant, and ... be sufficiently accurate and comprehensive to reasonably apprise such participants and beneficiaries of their rights and obligations under the plan.” 29 U.S.C. § 1022(a). Given the important informational role SPDs play under the ERISA scheme, it would be improper to ignore the terms provided by the SPDs.
The plaintiffs further argue that, even considering the reservation of rights in the SPDs, a reasonable fact finder could conclude that the dental benefits are vested. They suggest that the best way to reconcile the reservation of rights in the SPDs and the language regarding lifetime benefits in the individualized summaries, is to read the reservation as only permitting the company to terminate the services of a particular dental plan provider, while continuing to be obligated to provide the plaintiffs with dental plan coverage.
No reasonable reader of the documents could reach that conclusion. The SPDs reserve to the company “the right ... to amend, modify, or terminate the Plan at any time.” Given the rule under ERISA that an employer is generally free at any time, absent an undertaking to the contrary, to cancel a welfare benefit plan,
see
Curtiss-Wright,
514 U.S. at 78, 115 S.Ct. 1223, this language can only be reasonably read to allow the company to terminate dental plan coverage.
See Gable,
35 F.3d at 856 (rejecting a similar argument). The only reasonable reading of the ERPs is that the company would provide lifetime benefits to its retirees
subject to
its reservation of the right to modify, alter, or terminate dental plan coverage should future circumstances require such changes.
The past practice of the company in the provision of retirement dental benefits confirms our conclusion.
See Allen,
967 F.2d at 698, 702 (relying, in part, on past practice in interpreting an ERISA severance pay plan). The company had provided non-union retirees with dental benefits well before the ERPs were created. The plaintiffs do not claim that the benefits provided during this time were vested. Rather, they argue the ERPs changed the prior practice, and are new ERISA plans that guarantee vested lifetime dental benefits. However, the reservation of the company’s right to amend, modify, and terminate the dental plan in the dental plan SPDs does not reflect such a change after the creation of the ERPs. The individualized plan summaries and program brochures that plaintiffs claim created the new ERISA plan clearly state that the plan documents are governing. The oral statements made by the company representatives which omitted the reservation are similarly insufficient to overcome the unambiguous reservation of rights in the plan documents.
See Bellino v. Schlum-berger Techs., Inc.,
944 F.2d 26, 32-33 (1st Cir.1991);
see also
29 U.S.C. § 1102(a)(1) (“Every employee benefit plan shall be established and maintained pursuant to
a written instrument.”
(emphasis added)). A number of courts have held that, since ERISA requires that plans be “established and maintained pursuant to a written instrument,” oral statements cannot amend the terms of an ERISA plan.
See, e.g., Perreca v. Gluck,
295 F.3d 215, 225 (2d Cir.2002);
In re Unisys Corp. Retiree Med. Benefit “ERISA” Litigation,
58 F.3d 896, 902 (3d Cir.1995).
B.
ERISA Breach of Fiduciary Duty
The plaintiffs’ alternative argument is that the company was in breach of its fiduciary obligation
as administrator of the retirement plans when it “misrepresented” the terms of that plan to the employees. We do not think that there is enough evidence to create a misrepresentation case here. The plaintiffs only claim that the company omitted the fact that the dental benefits could be terminated or amended during meetings prior to their participation in the ERPs. But the plaintiffs were put on notice of the company’s right to modify, amend, and terminate the plan by the individualized benefits summaries and program brochures, which pointed to the underlying plan documents that contained the reservation of rights.
IV.
For the foregoing reasons, we
affirm
the grant of summary judgment. The parties shall bear their own costs.
