was the only bidder for Cedar Point stock at the time it entered into'the agreement with MCA. Furthermore, Pearson was not seeking control of Cedar Point; its tender offer was for only 15 per cent of the stock. Finally, the fact that Pearson had agreed to pay MCA an additional amount for stock already purchased from MCA if certain contingencies occurred would not affect the price which a third person might be willing to offer for the remaining Cedar Point stock. The Add-on agreement did not create artificial barriers to the operation of the market place or “artifically affect[] market activity in order to mislead investors----” Sante Fe Industries, Inc. v. Green, 430 U.S. 462, 477, 97 S.Ct. 1292, 1302, 51 L.Ed.2d 480 (1977).
B.
The district court did not rule directly on the materiality of the Add-on agreement. The plaintiffs argue that the agreement was material to their decisions, and this being so, they were entitled to a presumption of reliance. In TSC Industries, Inc. v. Northway, Inc., 426 U.S. 438, 445, 96 S.Ct. 2126, 2130, 48 L.Ed.2d 757 (1976), the Supreme Court stated that materiality is an objective matter, “involving the significance of an omitted or misrepresented fact to a reasonable investor.” The Court went on to define the standard of materiality best suited to the policies of Rule 14a-9, which relates to the solicitation of proxies, as follows:
An omitted fact is material if there is a substantial likelihood that a reasonable shareholder would consider it important in deciding how to vote. This standard is fully consistent with Mills’ general description of materiality as a requirement that “the defect have a significant propensity to affect the voting process.” It does not require proof of a substantial likelihood that disclosure of the omitted fact would have caused the reasonable investor to change his vote. What the standard does contemplate is a Showing of a substantial likelihood that, under all the circumstances, the omitted fact would have assumed actual significance in the deliberations of the reasonable shareholder. Put another way, there must be a substantial likelihood that the disclosure of the omitted fact would have been viewed by the reasonable investor as having significantly altered the “total mix” of information made available.
Id. 430 U.S. at 449, 96 S.Ct. at 2132 (footnote omitted). This definition has been applied to tender offer cases as well. See Piper v. Chris-Craft Industries, Inc., 430 U.S. 1, 50, 97 S.Ct. 926, 953, 51 L.Ed.2d 124 (1977).
The tender offer which Pearson actually made did not trigger the Add-on agreement because the offer price was not higher than the price paid to MCA. Thus, it is difficult to see how a reasonable investor, determining whether to accept the Pearson tender, would have been influenced by knowledge that if the offer from Pearson had been higher than it actually was, Pearson would be obliged to make an additional payment to MCA.
C.
Assuming materiality of the Add-on agreement for purposes of decision only, however, we find that the record fully supports the conclusion of the district court that there was no reliance on the allegedly undisclosed Add-on agreement here. In fact, there was no reliance on any of the tender offer materials which were disseminated. The presumption of reliance set forth in
Affiliated Ute is not irrebuttable. Rather, it has been described as “essentially a rule of judicial economy and convenience designed to avoid the impracticality of requiring that each plaintiff shareholder testify concerning the reliance element.”

cert. denied, 454 U.S. 1092, 102 S.Ct. 658, 70 L.Ed.2d 631 (1981). This court held in
Chelsea Associates v. Rapanos, 527 F.2d 1266, 1271 (6th Cir.1975), that the rule of
Affiliated Ute does not prohibit dismissal of an action brought pursuant to section 10(b) and Rule 10b-5 when a court finds no reliance on the non-disclosed fact. While positive proof of reliance is not required for recovery in a nondisclosure case, if the defendant is able to prove that there clearly was no reliance,
