The plaintiffs in this suit under ERISA and section 301 of the TafNHartley Act are nine multiemployer pension and welfare funds established pursuant to collective bargaining agreements. The funds are complaining about delinquent contributions by a small Wisconsin construction company between 1993 and 1998, and they appeal from a grant of summary judgment largely in the defendant’s favor. The cross-appeal, which complains that the attorneys’ fees awarded by the district court were excessive in view of the plaintiffs’ lack of success on the merits, is premature on the view we take of the plaintiffs’ appeal. There are some differences in the issues raised by the different funds, but for the sake of simplicity, and without affecting the legal analysis, we’ll be able with one exception to confine our discussion to the fund related to the laborers’ union.
The defendant failed to make contributions during the four-year period covered *649 by the complaint on the schedule set forth in its collective bargaining agreement with the union. This much is conceded, but the district court permitted the defendant to offset against the fund’s claim the amount by which the contributions sought by the fund exceeded the level of employer contributions specified in the 1991 collective bargaining contract. Although that contract expired in 1993, it contained an “evergreen” clausq: if neither party terminated the contract, it would be renewed automatically. The union negotiated with other employers a successor contract increasing the amount of the required employer contributions, and submitted the new contract to the defendant too, but for unexplained reasons the defendant never signed it. Nevertheless the union billed the defendant for contributions at the new, higher rates specified in the successor contract— and the defendant paid, without a murmur (albeit often late), throughout the period embraced by the suit. It claims to have paid by mistake, having, it argues, by virtue of the evergreen clause no contractual obligation to contribute to the fund at any rate higher than that specified in the 1991 contract; and therefore it was entitled to the offset that the district court allowed it.
This is wrong on two grounds. The first is that the defendant’s conduct in paying the higher rates uncomplainingly shows that it acquiesced in a modification of the 1991 contract, accepting at least so much of the successor contract that the union had tendered to it as established a new schedule of employer contributions to the fund. Nothing in the law of contracts requires that a contract, whether original or modified, must be signed to be enforceable. The contract needn’t be in writing; if it is in writing, it needn’t be signed, provided there’s other evidence of acceptance, for example (a very pertinent example) by performance,

These are
general
common law principles that we’ve been reciting, however, and the common law that the federal courts have devised to govern disputes arising out of collective bargaining contracts and ERISA plans does not coincide at every point with the general law. For example, the rule whose vitality we questioned in
Autotrol, id.
that makes contractual clauses forbidding modification other than by a signed writing unenforceable is inapplicable to collective bargaining contracts for the reasons explained in

This purpose implies, it is true, a limitation to cases in which plan participants or beneficiaries are seeking larger benefits than the plan authorizes. See
Doe v. Blue Cross & Blue Shield United of Wisconsin,
We add for what it’s worth (the parties make nothing of the point) that the monthly remittance reports accompanying these payments contained a declaration signed by the defendant that it “agree[d] to be bound by all of the provisions (including making payments) relating to pension, health & welfare and vacation funds, as contained in the Milwaukee area multi-employer labor agreements covering employees in the trade for which this report is made, for our employees in such trade, for the duration of such labor agreements, and, further, agree[d] to be bound by the applicable trust agreements.” Boilerplate it was, but it was entitled to

Brown v. C. Volante Corp., supra,
In any event, merely because a payment is made by mistake doesn’t give the payor an automatic right to the return of the payment, and so doesn’t conclude the issue of offset. The payor’s rights are governed by the principles of the law of restitution. The propriety of the courts’ incorporating those principles into the common law of ERISA cannot be doubted.
Central States, Southeast & Southwest Areas Health & Welfare Fund v. Pathology Laboratories of Arkansas, P.A.,
But jurisdiction does not imply merit. If restitution would be inequitable, as where the payor obtained a benefit that he intends to retain from the payment that he made and now seeks to take back, it is refused. (For the general principle, see
Invest Almaz v. Temple-Inland Forest Products Corp.,
It is true that the record contains no evidence that the higher contributions demanded in the successor contract resulted in greater benefits actually received by the defendant’s employees, but that is immaterial for two reasons. The first is that most of the benefits are in the nature of insurance or are otherwise contingent or (as in the case of pension benefits) deferred, so that immediate receipt is not expected; and insurance is not illusory just because the event insured against never occurs. Second, had the defendant refused to contribute at the new rate to the fund, the union would undoubtedly have terminated the (automatically renewed) 1991 collective bargaining agreement, as it was entitled to do, thus depriving the defendant’s employees of any pension and welfare benefits until the defendant knuckled under and signed the successor contract. By its apparent acquiescence in the benefits provisions of that contract, the defendant misled the union into thinking that the defendant was content with the new schedule of payments, and so the union forewent its alternative remedy of terminating coverage. The defendant’s conduct precludes a claim for restitution.
We turn now to the funds’ claim, not for the contributions that the defendant never paid—the district court allowed that claim though it whittled it down to very little with the offset that it erroneously granted—but for interest and penalties on the delinquent contributions. ERISA provides that in a suit for contributions the fund is entitled not only to the contributions but also to interest on them at the interest rate “provided under the plan” plus an amount equal to the greater of that interest or “liquidated damages provided for under the plan in an amount not in excess of 20 percent (or such higher percentage as may be permitted under Federal or State law) of the [unpaid contributions].” 29 U.S.C. § 1132(g)(2). The laborers’ plan fixes the interest rate at the legal maximum or 1.5 percent a month (not compounded, the parties agree), whichever is lower. The plan also provides for liquidated damages of 20 percent. The other plans provide only that a delinquent employer “shall be assessed liquidated damages and interest as determined by the Trustees,” but the trustees had fixed the interest rate at 1.5 percent a month also and liquidated damages at 20 percent.
Holding without explanation that the 1.5 percent rate was “illegal,” the court awarded interest to the fund at a 1 percent rate and required that the interest be calculated on a daily rather than, as sought by the fund, a monthly basis. The significance of this difference is that “calculated on a monthly basis” means that the employer would have to pay a full month’s interest no matter how short the delinquency—it might be only a day—whereas the court required the fund to prorate the interest according to the number of days of the delinquency. The court refused to award any liquidated damages at all. Its ground was that the fund had failed to show that 20 percent of unpaid contributions was a reasonable estimate of the damages caused to the fund by delay in payment, and therefore the so-called liquidated damages were actually a penalty and the common law does not permit penalty clauses in contracts.
The monthly calculation does seem a little odd, as it means that once the *653 employer misses the due date of a contribution by one day (or one minute, for that matter), he might as well delay until the last day of the month, since his interest expense is no greater and so he gets a month’s use of the money for zero interest. On the other hand the penalty for missing the due date by a day or a few days is greatly reduced by daily proration, which in the case of a delay of one day reduces the interest he must pay for being late from 1.5 percent (or 1 percent if the judge was right to cap the interest at that rate) to between l/28th to l/31st of that amount, depending on the length of the month.
How these effects balance out so far as inducing prompt payment is not for us, or the district court, to decide, and our point in mentioning the different incentives created by the two methods of calculating interest is merely to confirm that neither is so crazy that it can be ruled out as arbitrary and capricious. We think the plans must have intended to leave details of this sort to the discretion of the trustees. See
British Motor Car Distributors, Ltd. v. San Francisco Automotive Industries Welfare Fund,
As for the district court’s action in reducing the interest rate from 1.5 to 1 percent, there was no basis in law for that ruling either. The court may have been influenced by Wisconsin’s usury law, which fixes 12 percent as the maximum interest rate with various exceptions two of which are applicable here—the exception for corporations, Wis. Stat. § 138.05(5);
Sundseth v. Roadmaster Body Corp.,
As for applying the common law’s doctrine making contract penalty clauses unenforceable to liquidated-damages provisions in ERISA plans, the doctrine obviously is not intended to apply to statutory penalties and if it did so apply, it would be preempted. See
Idaho Plumbers & Pipefitters Health & Welfare Fund v. United Mechanical Contractors, Inc.,
The interest and liquidated-damages provisions of ERISA apply, however, only to contributions that are unpaid at the date of suit (not the date of judgment, as argued by the defendant).
Northwest Administrators, Inc. v. Albertson’s, Inc.,
Carpenters & Joiners Welfare Fund v. Gittleman Corp., supra,
The federal common law of ERISA may include a concept of unconseionability that would entitle an employer to complain if a fund’s trustees used the power delegated to it by the plan to establish a completely exorbitant interest rate on delinquent contributions. No case says that, but it may be encompassed by the principle that the trustees are not to act in an arbitrary and capricious manner. However that may be, 1.5 percent a month (or 18 percent a year) is not unconscionable— or at least the defendant made no effort to show that it was so exorbitant as to be unconscionable in the circumstances, and it is too late now for it to attempt to do so. Indeed, it doesn’t even call it “unconscionable,” but merely “oppressive,” which has no legal standing.
And while the ban on contractual penalties remains an established principle of the law of contracts, it is antiquated and should not be extended into ERISA-land— though two courts have done so already, see
Idaho Plumbers & Pipefitters Health & Welfare Fund v. United Mechanical Contractors, Inc., supra, 875
F.2d at 217-18;
In re Michigan Carpenters Council Health & Welfare Fund, supra,
To summarize, the funds are entitled to relief in accordance with the analysis in this opinion, and so the judgment must be reversed and the case remanded. The cross-appeal is dismissed because attorneys’ fees will have to be recomputed after the district court determines the amount of money that the defendant owes the plaintiffs.
