CALGARY, Alberta, Feb15: Encana Corp, Canada’s largest natural gas producer, ologized yesterday because one of its executives cursed after an analyst asked about whether new Canadian investment rules would prohibit its takeover by foreign state-owned entities. When asked the question by Canaccord Genuity analyst Phil Skolnick, interim CEO Clayton Woitas said: “The answer would be no.” Then, in a whispered comment that was clearly audible on a replay of the call, someone can be heard saying, “fucking asshole.” (agencies)
