OPINION
RIPPLE, Senior Circuit Judge:
On June 30, 2011, the Supreme Court of Arizona answered questions that we had certified to that court. Specifically, it determined that the rule of American Pipe & Construction Co. v. Utah, 414 U.S. 538, 94 S.Ct. 756, 38 L.Ed.2d 713 (1974), does not toll the statute of repose for construction-defect claims set forth in Arizona Revised Statutes section 12-552. Albano v. Shea Homes Ltd. P'ship, 227 Ariz. 121, 254 P.3d 360, 366 (2011). It also determined that Arizona's savings statute, Ariz.Rev. Stat. § 12-504(A), does not operate to save the appellants' claims. Albano, 254 P.3d at 367.
Following our receipt of these answers, we allowed the parties to file submissions to address whether there were any issues left to be resolved by this court. The appellees informed us that the Supreme Court of Arizona's clear responses to the certified questions were determinative of the matters before the court: Appellants' claims were time-barred. The appellants agree that the Supreme Court of Arizona's answers definitively resolve their claims. Nevertheless, relying on Chevron Oil Co. v. Huson, 404 U.S. 97, 92 S.Ct. 349, 30 L.Ed.2d 296 (1971), they ask that the rules articulated by the Supreme Court of Arizona be applied only in a prospective manner, thus exempting the appellants from the effects of those rules. We refuse to do so for several reasons.
First, the appellants never have argued that, in the event that the court concluded that American Pipe tolling did not save their claims, that determination should be nonretroactive. Having failed to raise this alternative claim in a timely manner, it is waived.
Second, Chevron Oil is inapplicable here.[1] As subsequent case law has made clear, Chevron Oil and its progeny articulate a methodology for determining when a federal court should apply a rule of federal law retroactively. See, e.g., Harper v. Va. Dep't of Taxation, 509 U.S. 86, 97, 113 S.Ct. 2510, 125 L.Ed.2d 74 (1993) ("When this Court applies a rule of federal law to *1123 the parties before it, that rule is the controlling interpretation of federal law and must be given full retroactive effect....").[2] When we consider a matter of state law, however, "[w]e are required, in exercising our appellate jurisdiction over this diversity case, to apply the law as presently defined by the highest court of [the State], despite the fact that the law was altered after the judgment below was entered." Nelson v. Brunswick Corp., 503 F.2d 376, 381 (9th Cir.1974) (citing Vandenbark v. Owens-Illinois Glass Co., 311 U.S. 538, 61 S.Ct. 347, 85 L.Ed. 327 (1941)).[3]
Even if we were free to deviate from the Vandenbark rule, however, the same result would obtain. "Normally, [Supreme Court of Arizona] decisions in civil cases operate retroactively as well as prospectively." Lowing v. Allstate Ins. Co., 176 Ariz. 101, 859 P.2d 724, 731 (1993). Although that court has "a great deal of discretion to decide the most equitable time to make new rules applicable," id. (internal quotation marks omitted), it gave no indication that its answers to the certified questions should be given only prospective application. On the contrary, we take judicial notice of the fact that the appellants, by way of a motion for reconsideration, specifically requested that the Supreme Court of Arizona "modify its Opinion to have a prospective effect only with regard to class action complaints filed after its date of decision" and that the Supreme Court of Arizona denied the appellants' motion for reconsideration.
Both of the parties agree that the Supreme Court of Arizona's answers to our certified questions put an end to the litigation before this court. Consequently, we now hold that, for the reasons articulated by the Supreme Court of Arizona, the appellants' claims are time-barred. The judgment of the district court dismissing *1124 the appellants' complaints is, therefore, affirmed.
AFFIRMED.
NOTES
[*]  The Honorable Kenneth F. Ripple, Senior United States Circuit Judge for the Seventh Circuit, sitting by designation.
[**]  Due to the death of the Honorable Pamela A. Rymer, the Honorable Sandra S. Ikuta, United States Circuit Judge for the Ninth Circuit, was drawn to replace her. Judge Ikuta has read the briefs, reviewed the record, and listened to the audio recording of oral argument held on June 16, 2010.
[1]  As the appellants note, this court recently has reaffirmed the vitality of Chevron Oil Co. v. Huson, 404 U.S. 97, 92 S.Ct. 349, 30 L.Ed.2d 296 (1971), in this circuit. See Nunez-Reyes v. Holder, 646 F.3d 684, 690 (9th Cir.2011) (en banc) (stating that "the three-factor Chevron Oil test remains good law, at least in cases, such as this one, where we announce a new rule of law not affecting our jurisdiction").
[2]  See also Lamb ex rel. Donaldson v. Volkswagenwerk Aktiengesellschaft, 631 F.Supp. 1144, 1151 (S.D.Fla.1986) ("[T]he Supreme Court's pronouncement in Chevron Oil would not determine the result of this law-suit even if Plaintiff had met its three-pronged standard.... Chevron Oil concerned the retroactive application of a federal decision involving federal law. The task of this Court in this diversity action is to reconcile this case with the current state of Florida law.").
[3]  We noted in Nelson, 503 F.2d at 381, that,

At the time the Vandenbark rule was adopted, it was undoubtedly thought to be a necessary extension of the Court's interpretation of the Rules of Decision Act in Erie R. Co. v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938). The rule has been criticized, we think perhaps justly, because it can lead to a difference in the result obtained in a federal and state court. In a state which engages in prospective overruling, the federal appellate court's application of the new rule will lead to a different result than would have resulted in a case pending in the state appellate courts if the new rule were not applied retroactively. The Vandenbark decision does not on its face seem to contemplate an independent determination of whether the state will apply a change in its rules of decision retroactively in ascertaining the law of a state; we apply Vandenbark as a "hard-and-fast" rule here. However, we do not think any difference would result from a more flexible approach, as our analysis of the Washington decisions indicates that Washington would probably apply this decision retroactively.
Id. at 381-82 n. 12 (citation omitted).
Since our decision in Nelson, several courts of appeals have commented that the rule in Vandenbark "may run afoul of Erie when the intervening change in state law would not have been applied retroactively by the state courts themselves." Moorhead v. Mitsubishi Aircraft Int'l, Inc., 828 F.2d 278, 289 (5th Cir. 1987); see also, e.g., Litton Sys., Inc. v. Am. Tel. & Tel. Co., 746 F.2d 168, 172 n. 6 (2d Cir. 1984) (reciting result in Vandenbark and noting that "[t]his result was reached to carry out the teaching of Erie ... though Erie probably required application only of state appellate decisions that the state court itself said were applicable to judgments previously entered but pending on direct review").
