Example: In an acquisition other than a tender offer, assume that requests for additional information are issued to both the acquiring and acquired persons on the 26th day of the waiting period. One person submits the additional information on the 35th day, while the other responds on the 44th day. Under this section, the waiting period expires thirty days following the last receipt of additional information, that is, it expires on the 74th day (unless that day is a Saturday, Sunday or legal public holiday).
