Dear Nishant as per my own understanding..Realisation A/c is prepared so as to close the books of account of the amalgamated companies.This is done by the payment of the liabilities that the amalgamted co. has prior to the amalgamation by its assets (in other words these items are taken to the new balance sheet at their book values).
The amount realised from the assets are used to pay off liabilities.
hence if Assets>Liabilities-Realisation profit(shown on the debit side of Realisation A/c) shared among the old shareholders
or if Assets<liabilities-Realisation Loss(which means the Co. did not have enough money to pay for the liabilities.also means the company is not getting anything from the reakoisation of assets,which is barely enough even to cover the liabilities amount)
furthermore im not totally convinced if the Realistion A/c is a nominal a/c ..because it contains items of Capital and Personal nature too..like Fixed Assets,Current Assets,Creditors etc.
I would rather say Realisation a/c is a mixture of Nominal,Personal,and Capital A/c
To conclude..Accounting is not an exact science,but its a mixture of art and science itself.Sometimes the rules are applicable,sometimes they are not.It is what you think it is..but sometimes its not what you think it is...
