This appeal, brought by various current, former, and retired sales agents of the Knights of Columbus, concerns a challenge to the Knights’ Pension Plan. Under the Knights’ plan, retirees receive a fixed pension benefit, but the amount is reduced by, among other things, any renewal commissions payable to the agent. Renewal commissions are benefits that a sales agent receivеs after having been with the Knights for five years.
See Bonovich v. Knights of Columbus,
The practiсe that the Knights’ pension plan has adopted, with respect to renewal eommis- *59 sions, is a form of pension integration. “Integration” occurs when a collateral source of income is folded into a retiree’s pension benefits, so that the pension plan’s obligation is reduced while the retiree maintains a constant level of income. In other wоrds, integration is a form of set-off: if an employee received a fixed payment per month, but then begins to receive additional payments from another source deemed appropriate, e.g., Social Security, a plan that “integrates” such benefits will reduce the amount payable by the plan, dollar-for-dollar, in response to the new sourcе of income. The effect is that the retiree’s income remains constant, but the pension plan pays a smaller portion of the total.
The plaintiffs in this appeal sought to initiate a class action to attack the integration of renewal commissions contained in the Knights’ pension plan. They contend first that this integration violates the nonforfeita-bility сlause of the Employee Retirement Income Security Act (“ERISA”), by divesting them of the portion of their entitled benefits that is offset by their renewal commissions.
See
29 U.S.C. § 1053(a) (“Each pension plan shall provide that an employee’s right to his normal retirement benefit is nonforfeitable upon the attainment of a normal retirement age.”). Defendants answer that the offset of renеwal commissions is nothing more than a part of the calculation algorithm that defines the ultimate pension benefits receivable. As such, they claim, the integration reflects a permissible agreement by the parties who negotiated and defined the pension plan.
See
29 U.S.C. § 1002(19),
interpreted in Nachman Corp. v. Pension Benefit Guaranty Corp.,
The United States District Court for the District of Connecticut (Janet Bond Arterton,
Judge),
in a comprehensive published opinion, rejected both contentions, and granted defendants’ motion to dismiss the plaintiffs’ suit.
See Bonovich,
On the forfeiture issue, the parties base their arguments on their rеspective readings of the Supreme Court’s opinion in
Alessi v. Raybestos-Manhattan, Inc.,
I. FORFEITURE
A.
In
Alessi
a group of retirees launched a global attack on the practice of integration, claiming that any integration violated the nonforfeiture clause of ERISA. But, as the Supreme Court pointed out, ERISA expressly provided for the integration of Social Security and Railroad Retirement benefits.
See id.
at 513,
*60
The Supreme Court rejected the retirees’ arguments. It concluded that integration does not necessarily violate ERISA. The High Court then both upheld the plan beforе it and refused to strike down the Treasury Regulation under attack. Of this much there is no doubt. What else
Alessi
did is, however, far from clear. And the lower courts have differed widely in their readings of the ease and its scope. (See Judge Cudahy’s insightful opinion in
Huppeler v. Oscar Mayer Foods Corp.,
The key point of contention has been the degree to which
Alessi
condones the practice of integration under ERISA. Some courts believe that
Alessi
should be read as a blanket endorsement of any form of integration.
See, e.g., PPG Indus. Pension Plan A v. Crews,
Courts that believe that the Supreme Court meant to cabin — at least to some extent — the practice of integration have tended to rely on Alessi’s discussion of certain revenue rulings issued by the IRS. These revenue rulings — some of which pre-dated the enactment of ERISA — did not deal with ERISA forfeiture at all, but concerned the interaction between integration аnd the anti-discrimination provisions of the Tax Code. Nevertheless, in speaking of some of these IRS rulings, the Supreme Court observed that:
[they] base their allowance of pension payment integration on three factors: the employer must contribute to the other benefit funds, these other funds must be designed for general public use, and the benefits they supply must correspond to benefits available under the pension plan. The IRS employed these considerations in approving integration with workers’ compensation benefits. E. g., Rev.Rul. 69-421, Part 4(j), 1969-2 Cu.Bull. 72; Rev.Rul. 68-243,1968-1 Cu.Bull. 157.
Alessi
By focusing on the third requirement of the revenue rulings cited in
Alessi
the courts that have upheld only some forms of integration have crafted a “nexus” test to determine whether or not benefits may be integrаted. Such a test requires that the integrated income stream’s payments bear some correlative relationship to the income-replacement function of pensions. Thus the Ninth Circuit, a leading nexus court, has ruled that
Alessi
forbids the integration of workers’ compensation payments that relate to restitution for bodily injury, because such benefit payments have no connection to the wage-replacing purpose of pensions.
See Pascoe,
Other courts have, instead, centered their attention
on the
parts
of Alessi
that focus on the parties’ freedom to establish, by contract, whatever plan they wish to create,

Our own circuit has expressly declined to weigh in.

Plaintiffs, in challenging the Knights’ integration practice, hone in on the rеvenue rulings discussed by the Supreme Court. They argue, relying on those circuits that have read the nexus requirement into the Alessi opinion, that the Supreme Court “adopted” the revenue rulings into the ERISA statute. And they contend that because the Knights’ provisions would fail at least some of the requirements of these rulings, the Knights’ integration of renewal commissions (unlike the integration of the workers’ compensation benefits at issue in Alessi) violates ERISA. Defendants, relying on the cases that have totally rejected the nexus requirement, respond that Alessi’s citation of the revenue rulings was no more than a passing reference, and that the Alessi Court in no way meant to make compliance with these revenue rulings a prerequisite for integration. They contend, instеad, that the essence of Alessi is to be found in the parts of the opinion that focus on the parties’ contractual freedom to establish whatever retirement plans suit them.
Although we think defendant’s characterization of the revenue rulings is the more accurate of the two, we need not (and hence do not) read
Alessi
as going so far in the contractual freеdom direction as defendants urge. As an initial matter, we believe that the defendants are correct in concluding that the Court’s discussion of the revenue rulings was unnecessary to its resolution of
Alessi:
4
Accordingly, we reject plaintiffs’ argument that the alleged failure of the Knights’ plan to meet the IRS’s three-part test precludes comportment with ERISA. And we hold that no such test is requirеd by
Alessi
In this regard, we are apparently in agreement with the Seventh Circuit.
See Huppeler,
We note, however, that dismissal of the significance of the revenue rulings does not conclude the nexus debate. In this regard, we evidently disagree with the Seventh Circuit.
See Huppeler,
C.
The renewal commissions provided by the Knights’ plan are not readily comparable to other benefits, such as restitution for bodily impairment, whose integration have been successfully attacked as inconsistent with ERISA.
See, e.g., Pascoe,
Like the plans that have been upheld, the private payments before us confer pecuniary benefits that serve the basic function of pensions, namely, to take the place of wages for retirees. That is the heart of the nexus “requirement.” They do not arise independently of the employment relationship. They are not, that is, like lottery winnings by the pensioner, integration of which would constitute a windfall for the employer. Nor do they constitute reimbursements fоr special expenses or burdens that have fallen on the retiree. They are not, that is, like compensation payments for physical injuries or pain and suffering, which, if integrated, would undercut the wage-replacement function of the pension plan.
Finally, the renewal commissions cannot be construed as being previously earned and vested deferred wages, whose payment is being spread out over five years. In this respect, it is critical that the benefits are private, discretionary, indefinite in amount, and that — in a significant sense — it was up to the employer and employees to define their scope in contractual negotiations. Thus, had the parties been so inclined, they could have made the renewal commission a bonus that was limited to those agents who had been with the Knights for five years and who remained in active service with the Knights. The fact that, instead, they chose to define the renewal commissions as available to all five-year agents, including those in retirement, but then to restrict the total retirement benefits (by integrating these commissions into the pension plan) in no way raises the spectre of “forfeiture.” 5
Under the circumstances, and because of their wage-related nature (and wage-replacing function for retirees), we find that the renewal commissions satisfy whatever nexus requirement Alessi could be read to mandate. And we decline to answer the question we left open in Reslca: does ERISA permit the integration of payments into a pension plan in the absence of a nexus between those payments and that plan?
II. ESTOPPEL
We therefore turn to the issue of the proper application of the equitable estoppel doctrine to ERISA cases. Specifically, we must consider plaintiffs’ contention that since the Knights describe their pension plan as “noncontributory,” they are estopped from defending the intеgration of the agents’ renewal commissions into the plan.
The district court conducted an analysis under
Schonholz v. Long Island Jewish Medical Center,
The Second Circuit has held that the principles of estoppel apply in ERISA cases only under extraordinary circumstances. Schonholz v. Long Island Jewish Medical Center,87 F.3d 72 , 78 (2d Cir.1996); Lee v. Burkhart,991 F.2d 1004 , 1009 (2d Cir.1993). The elements of a promissory es-toppel claim in an ERISA action are: (1) a promise, (2) reliance on the promise, (3) injury caused by the reliance, and (4) an injustice if the promise is not enforced. Schonholz,87 F.3d at 79 . Further, for purposes of ERISA, a plaintiff must demonstrate a promise that the defendant rea *63 sonably should have expected to induce action or forbearance on the plaintiffs part. Id.
Bonovich,
The district court concluded that the plaintiffs had not met these requirements. On appeal, the defendants argue that the district court should not even have initiated an estop-pel analysis because the lack of a facial ambiguity in the terms of the pension plan imposes a threshold bar on a plaintiff seeking to bring an estoppel claim. This argument finds its roots in
Kane v. Aetna Life Insurance,

rule is not the law in this circuit.

III. CONCLUSION
Because of the confusion that pervades this area of the law — a field that hungers for clarification from higher sources — we will summarize what we have held. First, we reiterate that the Supreme Court in
Alessi
did nothing more than reject the argument that Social Security and Railroad Retirement benefits were the only inсome streams inte-gratable under ERISA. And, in so doing, it understandably upheld a challenged Treasury Department Regulation that was consistent with its basic holding. Second, we conclude that the
Alessi
Court’s discussion of certain IRS revenue rulings was not meant to deem compliance with those rulings (or with their supposed three-part test) as the determinant of whether benefits may be integrated under ERISA. Third, we caution that our holding does not construe
Alessi
as foreclosing a “nexus” requirement in assessing the legality of the integration of independent sources of income into pension plans. As we have held before, that is an open question in our circuit.

AFFIRMED.
Notes
. 26 CFR § 1.411(a)-4(a) states: "[N]onforfeitable rights are not considered to be forfeitable by reason of the fact that they may be reduced to take into account benefits which are provided under the Social Security Act or under any other Federal or State law and which are taken into account in determining plan benefits.” Id. (emphasis added).
. According to
Huppeler,
the
Alessi
opinion began with a distinction that is logically unstable: namely, that there is a difference between the definition of a retiree’s pension benefit and a contractual deprivation of a pre-defined benefit.
See Huppeler,
. The district court in the proceedings below wrote: "In short, an offset does not violate ERISA merely because there is no identity of purpose between the pension payments and the purposes of the other integrated benefits.”
Bonovich,
. One explanation for the Court's reference to the rulings might simply be that they provided context for its decision to uphold the specific Treasury Regulation being challenged; i.e., that the Court meant to show that the IRS had considered matters of integration in the past, albeit in a different context.
. The fact that renewal commissions are apparently paid to agents who — after at least five years of service — leave the Knights for reasons other than retirement also does not mean the commissions are deferred compensation. Far from it. As to these recipients, the commissions can readily be seen to be a form of severance benefit given only to longtime employees.
