(1)    Withholding for after-acquired shares. A bank may elect to withhold payment required by s. 221.0713 from a dissenter unless the dissenter was the beneficial owner of the shares before the date specified in the dissenters’ notice under s. 221.0710 (2) (c) as the date of the first announcement to news media or to shareholders of the terms of the proposed corporate action.

   (2)   Payment. To the extent that the bank elects to withhold payment under sub.

The bank shall send with its offer a statement of its estimate of the fair value of the shares, an explanation of how the interest was calculated, and a statement of the dissenter’s right to demand payment under s. 221.0716 if the dissenter is dissatisfied with the offer.
