 In broad terms, a selective buyback is one in which identical offers are not made to every shareholder, for example, if offers are made to only some of the shareholders in the company.In the United States, no special shareholder approval of a selective buyback is required.In the UK, however, the scheme must first be approved by all shareholders, or by a special resolution (requiring a 75% majority) of the members in which no vote is cast by selling shareholders or their associates.
