(1) In this Instrument,
(a) the market price of a class of securities for which there is a published market, at any date, is an amount equal to the simple average of the closing price of securities of that class for each of the business days on which there was a closing price in the 20 business days preceding that date,
(b) if a published market does not provide a closing price, but provides only the highest and lowest prices of securities traded on a particular day, the market price of the securities, at any date, is an amount equal to the average of the simple averages of the highest and lowest prices for each of the business days on which there were highest and lowest prices in the 20 business days preceding that date, and
(c) if there has been trading of securities in a published market for fewer than 10 of the 20 business days preceding the date as of which the market price of the securities is being determined, the market price is the average of the following prices established for each day of the 20 business days preceding that date:
(i) the average of the closing bid and ask prices for each day on which there was no trading; and
(ii) either the closing price of securities of the class for each day that there has been trading, if the published market provides a closing price, or the average of the highest and lowest prices of securities of that class for each day that there has been trading, if the published market provides only the highest and lowest prices of securities traded on a particular day
(2) If there is more than one published market for a security, the market price in paragraphs (1)(a), (b) and (c) must be determined as follows:
(a) if only one of the published markets is in Canada, the market price must be determined solely by reference to that market;
(b) if there is more than one published market in Canada, the market price must be determined solely by reference to the published market in Canada on which the greatest volume of trading in the particular class of securities occurred during the 20 business days preceding the date as of which the market price is being determined;
(c) if there is no published market in Canada, the market price must be determined solely by reference to the published market on which the greatest volume of trading in the particular class of securities occurred during the 20 business days preceding the date as of which the market price is being determined.
(3) Despite subsections (1) and (2) for the purposes of section 4.1 and subsection 4.8(3), if an offeror acquires securities on a published market, the market price for those securities is the price of the last standard trading unit of securities of that class purchased, before the acquisition by the offeror, by a person who was not acting jointly or in concert with the offeror.
