Are you asking about Dividend Received by Subsidiary or Dividend Declared by Subsidiary company?
In case of Dividend Received AS 9 permit the recognition only when right to receive dividend arise i.e. when declared in AGM. Hence Dividend of last year (Say FY 2013-14) should be surrendered as income only in the FY 2014-15 after declaration thereof in the AGM of Paying Company.

But in question it is generally assumed that expense in P&L is charged only when liability to pay has arise i.e. declaration in AGM
