If you have total assets total liabilities and share holders fundshow do you figure out the net income?

The three items mentioned, total assets, total liabilities and shareholder funds, on their own, cannot be used to figure out net income.

To figure out net income for a period, one would need the above information for the beginning of the period and the end of the period. From there, a net income estimate could be derived; however, the values would not be exact without detail from each of the sections of the balance sheet.
