The appellant (Parnell) seeks relief from a jury award to the appellees (Uricos) for the loss of use to them of their truck, following its collision with another truck driven by a Parnell employee. Parnell’s primary theories here are that the district court erred 1) in allowing the jury to consider evidence of settlement negotiations, 2) in failing to limit loss of use damages to a reasonable repair period, and 3) in allowing the Uricos to calculate loss of use damages on the basis of their estimated lost profits.
I
The underlying facts are novel and require somewhat detailed exposition. On April 11, 1977, a truck driven by a Parnell employee struck the rear of one owned by the Uricos. The Uricos’ truck had been leased by them to Richard Lester. Without permission from the Uricos, Lester had turned the truck over to Harold Windsor who was its operator at the time of the accident.
Shortly after the accident, Parnell’s insurer, Bankers and Shippers Insurance Co. (B & S), contacted Windsor, arrived at a settlement, and issued checks in the amount of $15,102.05 for repairs and $3,500 for loss of use of the truck. B & S later stopped payment on the repair check when it learned that Windsor failed to retrieve the repaired vehicle.
The Uricos did not learn of the accident until June of 1977. They then informed B & S that Windsor lacked authority to reach a settlement on their behalf. Later, in Au *854 gust of 1977, they made a demand on B & S of $19,490.13 for property damage and $1,000.00 a week for loss of use. B & S took the position that it had already settled the claim with Windsor, but would be willing to pay the Uricos $15,102.05 for repairs if they, in turn, would waive their loss of use claim. The Uricos rejected this offer.
The truck had been repaired by the end of August, 1977, but the Uricos were unable to pay for the repairs and so could not take possession of it. The truck remained at the repair garage until September of 1979 when, by order of the district court, B & S issued a check to the Uricos in the amount of $15,102.05.
At trial, the Uricos sought damages for the loss of the truck’s use from the time of the accident until B & S made payment for the repairs under court order. The Uricos’ theory at trial was that B & S’s wrongful refusal to make a reasonable settlement offer prevented them from mitigating their damages during the post-repair period. The jury found in favor of the Uricos, awarding $11,400.00 for loss of use during the repair period, and $51,100.00 for loss of use following repair.
II
Parnell contends that the jury was prejudiced by the admission of testimony which detailed settlement discussions between the Uricos’ then attorney and B & S. Parnell relies on those provisions of Rule 408 of the Federal Rules of Evidence which state that:
Evidence of (1) furnishing or offering or promising to furnish, or (2) accepting or promising to accept, a valuable consideration in compromising or attempting to compromise a claim which was disputed as to either validity or amount, is not admissible to prove liability for or invalidity of the claim or its amount. Evidence of conduct or statements made in compromise negotiations are likewise not admissible. 1
But, Rule 408 has greater flexibility than that suggested by Parnell. It also provides that “[t]his rule does not require exclusion when the evidence [of settlement negotiations] is offered for another purpose . ... ” For example, evidence concerning negotiations may be admitted to establish admissions of fact rather than “hypothetical or provisional concessions conditioned upon th£ settlement’s completion.”
Hiram Ricker & Sons v. Students International Meditation Society,
The Uricos had a clear duty to take all reasonable steps to mitigate damages.
See, e.g., McKenna v. Commissioner of Mental Health,
Moreover, Parnell’s claim of prejudice is undermined by its tactics at trial. By way of defense, Parnell attempted to prove that Windsor was authorized to settle the claim on behalf of the Uricos and that the Uricos, therefore, were barred from any further recovery. 5 In pursuing this evidentiary theory, Parnell introduced the testimony of a B & S insurance adjuster. Such an approach is inconsistent with Parnell’s contention here that the mere mention of insurance may have prejudiced the jury. 6
Ill
Ordinarily, recovery for loss of use of a damaged vehicle is limited to that period of time reasonably necessary to complete repairs.
Antokol v. Barber,
The extension of loss of use damages beyond the repair period raises difficult policy questions. Limiting loss of use damages to a reasonable repair period recompenses the plaintiff for a finite period in which the vehicle is simply unavailable for use. An award of loss of use damages after the vehicle has been repaired, however, is potentially boundless. Anticipation of such an award could conceivably reduce any incentive that a plaintiff might have to mitigate losses. The evidence here, however, relieves us of these theoretical concerns. The Uricos, despite their good faith best efforts, could not mitigate their losses without possession of the repaired truck. B & S knew this. Nonetheless, B & S refused to issue payment for the repairs, despite the fact that they had previously done so to an unauthorized party.
Arbitrary conduct by an insurer, which serves to prolong rather than contain the interval of loss, is an appropriate circumstance for awarding damages beyond
*856
the traditional reasonable repair period. In
Valencia v. Shell Oil Co.,

Parnell also claims that the district court,
Parnell raises a number of additional objections to the manner in which damages were calculated. These objections are without merit. Contrary to Parnell’s claims, the evidence of lost profits took into account overhead, and the trial judge specifically instructed the jury to consider damages only as to the damaged trailer and not as to the undamaged tractor. Finally, Parnell asserts that the Uricos’ vehicle was a constructive total loss and so no loss of use damages may be awarded for it. B & S, however, clearly took the position that the trailer was reparable and, in fact, arranged for its repair. Parnell may not at this stage dissociate itself from B & S’s pre-trial tactical choices.
Affirmed.
Notes
. Parnell also cites Mass.Gen.Laws ch. 231, §§ 140B & 140C, for the proposition that the mere mention of insurance is highly prejudicial. We doubt that these statutes would be construed by the Massachusetts courts to go so far as to exclude reference to insurance settlements in the circumstances of this case. But even if the statutes would exclude the evidence, the controlling law here would appear to be the federal rules of evidence which permit such reference in appropriate circumstances, rather than the state statutes.
See Johnson v. William C. Ellis & Sons Iron Works, Inc.,
. The jury found that Parnell was 90% negligent and that Windsor’s contributory negligence amounted to 10%.
. Parnell claims that it was error to regard B & S as Parnell’s agent, thereby ascribing to Parnell the consequences of B & S’s unreasonable settlement negotiations. The evidence, however, supports a finding that Parnell authorized and relied on B & S’s settlement negotiations. There was no evidence that Parnell undertook independent efforts to negotiate with the Uri-cos. B & S’s unreasonable failure to settle the claim, or at a minimum, to put the Uricos in a position where they would no longer incur loss of use damages, may therefore be fairly imputed to Parnell.
See Hayes v. Gessner,
. This case is readily distinguishable from our recent decision in
Almonte v. National Union Fire Insurance Co.,
. On appeal, Parnell again argues that the settlement with Windsor barred recovery by the Uricos. Evidence at trial, however, demonstrated unequivocally that Windsor had no authorization to settle and that the insurer knew of the Uricos’ ownership of the truck almost from the outset. The jury explicitly found, in response to a special interrogatory, that Windsor was not authorized to settle.
. In this regard, Parnell’s reliance on
Parento v. Palumbo,
. That the Supreme Judicial Court of Massachusetts (SJC) would follow
Valencia
if presented with the precise question is forecast by its recent decision in the case of
DiMarzo v. American Mutual Life Insurance Company,
DiMarzo
also serves to foreclose the Uricos’ position that Mass.Gen.Laws chs. 93A § 9 and 176D provided them with a statutory right of action against B & S. In
DiMarzo,
the SJC held that, as of the 1979 amendment to ch. 93A § 9, such a right of action extends to “any person ‘injured’ by another person’s unfair or deceptive act or practice.”
DiMarzo v. American Mutual Life Insurance, supra,
389 Mass, at 93 n. 7,
. Parnell urges as well that the rental value of a similar trailer for the period in question would have fully compensated the Uricos. The evidence established, however, that an award based on fair rental value would have been substantially less than the Uricos’ lost profits. The district court, therefore, properly admitted evidence of lost profits to ensure that the Uri-cos would be fully and fairly compensated.
