This matter comes before this court upon a petition for leave to file an interlocutory appeal under 28 U.S.C. § 1292(b) 1 from a discovery order of the district court. Because we find that the district court abused its discretion in certifying this interlocutory appeal, we dismiss this appeal for lack of jurisdiction.
I.
The underlying diversity action arises out of the construction of a soybean crushing plant in Union County, Iowa. The construction of the mill was to be undertaken by CF Processing, a wholly owned subsidiary of Crestland Cooperative. The petitioner, Union County, Iowa (the “County”), alleges that the respondent, Piper Jaffray & Co., Inc., provided the County with advice regarding the County’s issuance of two General Obligation Capital Loan Notes (the “bond offerings”) in connection with the project. In total, the bond offerings amounted to $5,865 million. The mill was to be assessed for property tax purposes at a certain amount, and if the tax revenue generated on that assessment failed to cover debt service on the notes, CF Processing agreed to pay any shortfall in order for the County to make the required debt service payments. In turn, Crestland guaranteed CF Processing’s performance.
CF Processing and Crestland filed bankruptcy in 2001, defaulting on all obligations to the County, when the tax shortfall occurred. The County filed suit against Piper Jaffray, asserting claims of breach of fiduciary duty, breach of contract, negligent misrepresentation, negligence, and fraud. The crux of the County’s ease is that Piper Jaffray failed to properly advise the County of (1) material information and risks involved in the issuance of the bond offerings in the event of defaults by Crest-land and CF, and (2) alternative financing options.
After requesting documents and/or information concerning the professional advice the County received in connection with the bond offerings, Piper Jaffray filed a Motion to Compel, asserting that the County had refused to provide the documentation sought. The County asserted, through a privilege log, that the documents were not discoverable under the work product doctrine and attorney-client privilege. The magistrate judge granted the motion in part and denied it in part, specifying the documents that were to be produced because the County had waived the attorney-client privilege with regard to the information contained in those documents as a result of the litigation it had undertaken against Piper Jaffray. The district court affirmed; in its order, however, the court certified the case for interlocutory appeal pursuant to 28 U.S.C. § 1292(b). The County then petitioned this court for permission to file the appeal.

Because “[t]he requirements of § 1292(b) are jurisdictional,”
White v. Nix,
*646
In requesting that this court follow the extraordinary course of interlocutory review of this matter, “the [County] bears the heavy burden of demonstrating that the case is an exceptional one in which immediate appeal is warranted.”
White,
First, the motion to compel was granted by the district court based upon waiver of attorney-client privilege. We assume without deciding that the district court’s order, premised upon its resolution of the attorney-client privilege issue, involves a controlling question of law.
See id.
at 377 n. 3 (stating that appellants’ argument that files were protected against discovery by “some privilege” presents a controlling legal issue as to the existence of the privilege). However under § 1292(b) there must also exist “substantial basis for difference of opinion” with respect to such question.
Id.
Because this is a diversity case, the determination of whether attorney-client privilege applies is governed by state law. Fed.R.Evid. 501 (providing that state law supplies the rule of decision on privilege in diversity cases);
see Pamida, Inc. v. E.S. Originals, Inc.,
Under Iowa law, a client may waive attorney-client privilege. Iowa Code § 622.10(2);
see Miller v. Continental Ins. Co.,
With regard to the third statutory requirement, that the certification will materially advance the ultimate termination of the litigation, the district court quoted this portion of the statute, however, we do not see how the court’s only stated reason for certifying the appeal — the lack of Eighth Circuit precedent — demonstrates that this requirement has been met. Though this criterion may be satisfied here, the district court should make the necessary findings to demonstrate that this statutory criterion was satisfied.
See id.
(“Although the district court quoted this portion of the statute, it made no mention of it when making the necessary findings. Thus, we conclude that the district court failed to consider this statutory criterion.”);
see also Isra Fruit Ltd. v. Agrexco Agri. Export Co.,
Finally, while this court has previously considered an interlocutory appeal relating to attorney-client privilege,
see Simon v. G.D. Searle & Co.,
III.
We conclude that the district court abused its discretion in certifying this interlocutory appeal where the statutory cri *648 teria were not satisfied. Accordingly, we dismiss this appeal for lack of jurisdiction.
Notes
. Section 1292(b) provides:
When a district judge, in making in a civil action an order not otherwise appealable under this section [that disallows interlocutory appeals with certain exceptions], shall be of the opinion that such order involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation, he shall so state in writing in such order. The Court of Appeals which would have jurisdiction of an appeal of such action may thereupon, in its discretion, permit an appeal to be taken from such order....
