The peak of this phenomena took place at the end of March and it is the end of the financial year 2011.
The standards followed to prepare the financial statements ask to adjust the foreign exchange loss or gain at the end of the financial year.
But it does not ask to re-state or mention in notes as a post balance sheet event the appreciation of rupee after 31- March.
The effect on financial statements year ended 13 March 2012 is overstating of foreign exchange gain as now US$ has came down to Rs.128/-
At 31-March it was at Rs.131/-
This difference will depict in large numbers if they are dealing with foreign currencies significantly.
