Class Action, page-154

I have only done a master degree in financial accounting not PHD.But I can read and analyse financial statements like Balance sheet, cash flow, profit and loss accounts. Based on this knowledge, I earned $ in more than 6 digits few years back .Unfortunately, I have zero idea as to how registration in class action could benefit me as a shareholder.Do not worry about my financial knowledge, please. Educate me on legal aspects of class action. Thank you
