Except as provided in § 801.13 , the value of voting securities and assets to be acquired shall be determined as follows:
Example: Corporation A, the ultimate parent entity in person "A," contracts to acquire assets of corporation B, and the contract provides that the acquisition price is not to be determined until after the acquisition is effected. Under paragraph (b) of this section, for purposes of the act, the value of the assets is to be the fair market value of the assets. Under paragraph (c)(3), the board of directors of corporation A must in good faith determine the fair market value. That determination will control for 60 days whether "A" and "B" must observe the requirements of the act; that is, "A" and "B" must either file notification or consummate the acquisition within that time. If "A" and "B" neither file nor consummate within 60 days, the parties would no longer be entitled to rely on the determination of fair market value, and, if in doubt about whether required to observe the requirements of the act, would have to make a second determination of fair market value.
