Meanwhile, Imperial Oil on Wednesday said it will ask the Toronto Stock Exchange for permission to continue its existing share repurchase program facility that will expire on June 22, 2007. This would let Imperial buy back as much as 5% of its issued and outstanding shares on the date of acceptance by the Toronto Stock Exchange during the 12 months after purchases begin.
Acceptance is expected on June 21, Imperial Oil said in a statement.
The company has approximately 934 million shares outstanding.
"Exxon Mobil Corporation has advised Imperial that it will participate in the new program as it has in the existing one, to maintain its ownership percentage in Imperial at 69.6 percent," the statement said.
