FSTM - parent companies SFP quick question

Rosierabbit

can someone explain to me when we are working out the Statements of Financial Position why we don't apportion the subsidiaries current assets and current liabilities. That is if a parent company owns 90% of a subsidiary you don't add only 90% of the current assets and liabilities of the subsidiary to the Statement of Financial Position. Also why in the Equity section you only include the Share Capital of the Parent company, but review the retained earnings to include a percentage of the amount the retained earnings have increased over the year of the subsidiary plus the retained earnings of the parent company.

Thank you so much
