Hello, I need an explanation and answers for the following questions from the finance people's point of view:

1. Why there is a need to reformulate Income Statement? Why can't financial managers with challenging approach to use in financial analysis directly use reported Income Statement?
2. Why there is a need to reformulate Balance Sheet? Why can't financial managers with challenging approach to use reported Balance Sheet in financial analysis directly?
3. Why there is a need to reformulate Statement of Shareholders Equity? Why can't financial managers with challenging approach to use reported Statement of Shareholders Equity in financial analysis directly?
4. Why there is a need to reformulate Statement of Cash Flows? Why can't financial managers with challenging approach to use reported Statement of Statement of Cash Flows in financial analysis directly?

I know that probably mostly the answers should be based on the need for separation between activities (differentiation of operational activities and financial ones). However, I really need some specific details for the answers. For example, in the 3rd question there might be said that the way of how the dividends are recognized one of the reasons for the reformulation and etc. Thank you in advance. I would be happy if you'll help me out since there are 2 hours before the submission , but I could not answer these questions without full understanding of what going on there. Thank you in advance, my dear tutor <3
