Final answer:
Statement D is false; a significant reduction in the shareholder's percentage of ownership and voting power is enough for a stock redemption to qualify as an exchange rather than a dividend.
Step-by-step explanation:
The question pertains to stock redemptions pursuant to the Internal Revenue Code (IRC) and their consequences on taxes. Specifically, it involves IRC § 302 and § 303, which address stock redemptions treated as exchanges and those under estate taxation scenarios, respectively.
Statement D is false because, for a stock redemption to be not essentially equivalent to a dividend under IRC § 302(b)(1), it is not necessary that there be a material change in the relative economic interests or rights of the respective shareholders. In certain situations, a significant reduction in the shareholder's percentage of ownership and voting power is enough to ensure the redemption is treated as an exchange rather than a dividend.
