As used in this chapter, the following words, unless the context clearly requires otherwise, shall have the following meanings:
If this chapter applies to an issuing public corporation at the time a person makes a control share acquisition, all shares of such issuing public corporation the beneficial ownership of which is acquired by such person within ninety days before or after the date on which such person makes an acquisition of beneficial ownership of shares which results in such control share acquisition, regardless whether this chapter was in effect or applies to such corporation during such ninety day period, and all shares acquired by such person pursuant to a plan to make a control share acquisition, shall be deemed to have been acquired in the same control share acquisition for purposes of this chapter.
The record date for determining the percentages and numbers of stockholders and shares specified in this subsection shall be the last stockholder record date before the control share acquisition as to which the determination is being made or, if earlier, before the date on which a control share acquisition statement relating thereto is filed under the provisions of section three. A stockholder record date is the date fixed by the board of directors or, if applicable, the date when transfer books are closed by the board of directors, in connection with determining stockholders entitled to notice of and vote at a meeting or to consent or dissent, to receive any dividend or other distribution, or for the purpose of any other lawful action. If a stockholder record date has not been fixed by the board of directors within the preceding four months, the determination shall be made as of the end of the issuing public corporation's most recent fiscal quarter.
The residence of each stockholder is presumed to be the address appearing in the records of the corporation. Shares held of record by brokers or nominees shall be disregarded for purposes of calculating the percentages and numbers specified in this subsection. Any shares of an issuing public corporation allocated to the account of an employee or former employee, or beneficiary of an employee or former employee, of such corporation and held in a plan that is qualified under section 401(a) of the Internal Revenue Code of 1986, as amended, and is a defined contribution plan within the meaning of section 414(i) of said Code shall be deemed, for the purposes of clause (iii), to be held of record by the employee, former employee or beneficiary to whose account such shares are allocated.
