The claim also records that TransAlta had rebuffed multiple offers by Brookfield to acquire the entire Company over the past several years, only acceding to Brookfield's repeated entreaties when faced with an imminent proxy contest. Nathaniel August, President and Portfolio Manager at Mangrove Partners, said, "The TransAlta Board has made every effort to obscure the true process by which the Brookfield transaction came to pass and their motives for entrenching themselves at the expense of shareholders. As a large and engaged shareholder of TransAlta, we cannot allow this conduct by the Board and its Special Committee to go unchallenged. So, at TransAlta's own recommendation, we have brought an oppression action and will seek to hold TransAlta accountable to its shareholders."
