In this appeal, plaintiff-appellant Monica Santiago challenges the district court’s entry of summary judgment against her and in favor of defendants-appellees. 1 In so doing, plaintiff advances three arguments: (1) the legal issues in this appeal should be certified to the Massachusetts Supreme Judicial Court (“SJC”); (2) the district court erred in rejecting plaintiffs market share liability argument; and (3) the court erred in rejecting plaintiffs concert of actiоn claim. After carefully reviewing each of plaintiffs arguments, we affirm.
I.
BACKGROUND
Plaintiff was born on November 9, 1972. From the time of her birth until 1978, she and her family resided at 20 Leston Street in Boston. Plaintiff alleges that, during her period of residence, she ingested lead paint that had been applied in layers to the walls and woodwork of her home at various times between 1917, the year of the building’s construction, and 1970. The evidence reveals that plaintiffs blood had highly elevatеd levels of lead by the time plaintiff was one year of age, that the lead reached emergency levels by July 1976, and that, as a consequence, plaintiff had to undergo chelation therapy 2 in order to remove the lead from her body. Although plaintiffs early development appeared to progress normally, she has been diagnosed with a hyperactivity-attention disorder and motor skill difficulties which her medical experts attribute to lead poisoning.
Plaintiff initiated this action in November 1987, contending that defendants, or their predecessors in interest, manufactured and marketed all, or virtually all, of the white lead used in the lead paints sold in the United States between 1917 and 1970. Her complaint set forth claims of negligence, breach of warranty, and concert of action. Jurisdiction was premised upon diversity of citizenship. See 28 U.S.C. § 1332.
Plaintiff could not and cannot identify either which, if any, оf the defendants are the source of the lead she ingested or when the alleged injury-causing paint may have been applied to the walls and woodwork of her childhood home.

She has, however, introduced (1) evidence in the form of expert testimony that lead paint “was at minimum a substantial contributing factor of her lead poisoning;” (2) evidence demonstrating that all of the defendants produced white lead for
By memorandum and order dated January 13, 1992, the district court rejected plaintiffs market share claim as a matter of Massachusetts law. In so doing, the court ruled that even if the SJC would recognize market share liability under some scenario, it would not do so if presented with the undisputed facts of this ease.

DISCUSSION
A. Certification
As an initial matter, plaintiff has requested that we certify to the SJC questions regarding the viability of market share liability and concert of action as theories of recovery in light of the facts of this case. We note that plaintiff first requested certification in this court, and explicitly stated her opposition to certification at the district court level. Now, having lost below, plaintiff has reversed her position. Unsurprisingly, defendants oppose plaintiffs certification request.
For reasons that are largely self-explanatory, we have held that “one who chooses to litigate [her] state action in the federal forum (as plaintiff did here) must ordinarily accept the federal court’s reasonable interpretation of extant state law rather than seeking extensions via the certification process.”
Croteau v. Olin Corp.,
Here, as will be demonstrated below, the district court’s interpretation of Massachusetts law was eminently reasonable. Furthermore, plaintiff, after initially deciding to eschew her prerogative to file this action in state court, actively made her opposition to certification known to the district court. In light of these facts, and given the further fact that it has been over five years since these federal proceedings were initiated, it would be extremely unfair to defendants if we were to allow plaintiff to relitigate the issues at the heart of this lawsuit. Accordingly, plaintiffs request for certification is denied. 4
B. Standard of Review
Having dispensed with plaintiffs certification request, we proceed to delineate the parameters of our examination. Summary judgment allows courts to “pierce the boilerplate of the pleadings and assay the parties’ proof in order to determine whether trial is actually required.”
Wynne v. Tufts Univ. Sch. of Medicine,
A fact is only material if it has “the potential to affect the outcome of the suit under the applicable law.”
Nereida-Gonzalez v. Tirado-Delgado,
Our review of a summary judgment ruling is plenary.
Garside,
In addition to examining the facts, a court passing on a summary judgment motion or reviewing a summary judgment determination must, of course, consider the applicable law. When a plaintiff invokes diversity jurisdiction to bring a state law claim in federal court, this survey is somewhat circumsсribed, for it is settled that, in ordinary circumstances, a plaintiff who “selects a federal forum in preference to an available state forum may not expect the federal court to steer state law into unprecedented configurations.”
Martel v. Stafford,
C. Market Share Liability
Plaintiff argues that the district court erred in granting defendants summary judgment on her claim for market share liability. In so doing, she concedes that the SJC has never explicitly endorsed a market share liability theory of recovery, and further recognizes that the court rejected a certаin species of market share liability advanced by plaintiffs in a DES class action.
See Payton v. Abbott Labs.,
As noted above, the SJC did have occasion to consider, by means of a certified question, the viability of one form of market shаre liability in a DES case.
See Payton,
We accept for the sake of argument plaintiffs assertions (1) that the SJC would, in some circumstances, relax the identification requirement and allow a plaintiff to recover under a market share theory; (2) that the SJC would recognize market share liability in the lead poisoning context; (3) that plaintiff has introduced sufficient evidence for a reasonable factfinder to infer that her injuries resulted from lead poisoning; (4) that lead paint was, as one of plaintiffs experts puts it, at least “a substantial contributing factor of her lead poisoning”; and (5) that defendants, who were mere bulk suppliers оf white lead and did not manufacture or market the alleged injury-causing paint, could still be adjudged to have acted negligently towards plaintiff. Nonetheless, we believe that the SJC’s professed interest in both holding wrongdoers liable only for the harm they have caused and in separating tortfeasors from innocent actors is fatal to plaintiffs claim.
Simply put, allowing plaintiffs market share claim to proceed despite plaintiffs inability to pinрoint with any degree of precision the time the injury-causing paint was applied to the house on Leston Street would significantly undermine both of the articulated reasons for the identification requirement. The record before us reflects that the layers of lead paint were applied to the house’s walls at various undeterminable points in time be
Moreover, several of the defendants were not in the white lead pigment market at all for significant portions of the period between 1917 and 1970, and therefore may well not have been market suppliers at the time the injury-causing paint was applied to the walls of plaintiffs home. This, of course, raises a substantial possibility that these defendants not only could be held liable for more harm than they actually caused, but also could be held liable when they did not, in fact, cause any harm to plaintiff at all. Under plaintiffs theory, therefore, tortfeasors and innocent actors would not be adequаtely separated.
Finally, we note that the dicta relied upon by plaintiff indicates that a relaxation of the identification requirement to allow recovery against a negligent defendant would only be appropriate to the extent that the recovery represents “that portion of a plaintiffs damages which is represented by that defendant’s contribution ... to the market in the relevant period of time." Id. at 190 (emphasis supplied). Here, as noted, plaintiff cannot identify with adequate specificity the relevant period of time. Thus, it appears that plaintiffs theory does not fall within even the vague parameters mentioned in the SJC’s dicta.
In sum, allowing plaintiff to recover her full damages from the five named defendants despite her inability to specify the time of their negligence may well, on this record, do violence to the SJC’s stated interest in ensuring that wrongdoers be held liable only for the harm they hаve caused. It also would create a substantial possibility that tortfea-sors and innocent actors would be impermis-sibly intermingled. The SJC has made it abundantly clear that it would not countenance either result. Accordingly, mindful that federal courts sitting in diversity at a plaintiffs election ought not “steer state law into unprecedented configurations,”
see Martel,
D. Concert of Action
Finally, plaintiff contends that the district coui’t erred in granting defendants summary judgment on her concert of action claim. Again, we cannot agree.
Plaintiffs concert of action claim is premised upon the theory of liability set forth in Section 876 of the Restatement (Second) of Torts (1977). In relevant part, Section 876 (entitled “Persons Acting in Concert”) provides:
For harm resulting to a third person from the tortious conduct of another, one is subject to liability if he
(a) does a tоrtious act in concert with the other or pursuant to a common design with him, or
(b) knows that the other’s conduct constitutes a breach of duty and gives substantial assistance or encouragement to the other so to conduct himself....
In isolated circumstances, Massachusetts courts have indicated their willingness to permit recovery under theories tracking the language of Section 876.
E.g., Orszulak v. Bujnevicie,
In essence, plaintiff claims that, “in light of the substantial medical evidence of the unreasonable risk that [lead paint] ‘posed to young children!,]” certain of defendants’ actions as members of the LIA between 1930 and 1945 were tortious. Specifically, plaintiff points to defendants’ “initiation of] nationwide promotional campaigns, encourage[ment of] the use of white lead in housе paint through extensive advertising, [attempts] to undermine the growing medical evidence of the danger of lead paint, and work[ ] to prevent the enactment of governmental regulations which would have restricted the use of white lead in painting buildings.”
10
What is utterly lacking from her presentation, however, is any evidence that these actions, during the fifteen year period she identifies, had
any
role in causing lead paint to be applied to the wаlls of her childhood home. Even if we assume that at least some of the lead paint consumed by plaintiff was applied to her home during the period of defendants’ alleged concerted actions, there is
no
evidence that the application resulted from these actions, or that it would not have taken place in the absence of these actions.
Cf. Roberts v. Southwick,
We acknowledge that the question оf causation is generally for the factfinder.

CONCLUSION
Because certification to the SJC of the issues raised in this appeаl would be inappropriate, plaintiffs request therefor is denied. Furthermore, because the district court correctly ruled that plaintiffs market share and concert of action claims fail as a matter of

Notes
. Defendants are Sherwin-Williams Company, NL Industries, Inc., Eagle-Picher Industries, Inc., Atlantic Richfield Corporation (successor to International Smelting & Refining Company), and SCM Corporаtion (successor to Glidden Company). On January 7, 1991, defendant Eagle-Picher filed for bankruptcy in Ohio, thus automatically staying this action against it. See 11 U.S.C. § 362.
. Chelation therapy is a procedure whereby a person with lead poisoning is given chemicals that bind with the lead, enabling the body to excrete it more rapidly.
.There is no direct evidence that plaintiff actually ate lead paint. There is, moreover, record evidence suggesting that, in addition to lead paint, plaintiff could have been exposed to airborne lead, lead from food and water, and/or lead from soil and dust. Indeed, there is evidence indicating that plaintiff's neighborhood, including the soil around her home, was heavily contaminated with lead.
. Despite the equitable arguments against certification in this case, in light of the importance of the matter, Judge Breyer would certify the issue to the Supreme Judicial Court.
. In Payton, an action brought by a сlass of women whose mothers ingested DES while pregnant with them, the United States District Court for the District of Massachusetts certified to the SJC the following question:
Assuming that the evidence does not warrant a conclusion that the defendants conspired together, or engaged in concerted action, or established safety standards through a trade association, may the defendant manufacturers, who probably supplied some of the DES ingested by the mothers of the plaintiff class, be held liable to members of the plaintiff class when neither the plaintiffs nor the defendants can identify which manufacturer's DES was ingested by which mothers?
Id. at 188. The SJC ruled that it could not answer the question in the form stated because the question "d[id] not explicitly assume that the plaintiffs will be able to establish the negligence of ... defendants.” Id. However, as is discussed more fully below, the court did set forth its general views on market share liability. In so doing, it rejected the theory of market share liability advanced by plaintiffs in that case. Id. at 189.
. In concluding its explicit rejection of the form of market share liability plaintiffs sought to impose, the Payton court stated:
That is not to say that on an adequate record this court would not recognize some relaxation of the traditional identification requirement in appropriate circumstances so as to allow recovery against a negligent defendant of that portion of a plaintiff's damages which is represented by the defendant's contribution of DES to the market in the relevant period of time.
Id. at 190.
. Plaintiff did introduce expert testimony attempting to date one of the multi-layered paint samples taken from the house. However, this expert was only able to say that one layer of lead paint probably was applied between 1933 and 1939, and that a second layer of lead paint was рrobably applied between 1955 and 1969.
. Apparently, plaintiff would have market share determined according to an average of defendants' market shares over time. Because such an approach would virtually guarantee a deviation between liability and actual culpability for all the named defendants, we are confident that the SJC would look upon it with disfavor.
.We are aware that the United States District Court for the District оf Massachusetts, relying on the dicta in
Payton,
approved a market share theory of recovery in a DES case.
See McCormack,
. Plaintiff acknowledges, however, that she has nо evidence that defendants ever concealed information or introduced false research into public debate.
. We recognize that the district court based its summary judgment decree on the fact that plaintiff was unable to identify any of the defendants specifically as tortfeasors.
