Your doubts are concepts related. The answers are as follows:-
1-- As per AS-14 , Purchase Consideration(PC) denotes amount paid to equity shareholders. Moreover, amalgamation takes place at ownership level i.e. owners are involved or equity shareholders. So in such case we don't take any amount due towards outsiders( Creditors or any outside 3rd party like Liquidator).
PC is to be given to owner & not to outsiders. In simple language, will you pay amount due to purchase of building to its owner or to any other 3rd party??? Obviously, you will pay to its owners to acquire ownership & not to any outsiders.
2-- Intrinsic value of shares means the real worth of Company shares & not merely its face value. To determine intrinsic value, we take net assets method because the value of shares is reflected in the form of Assets/ Outside liabilities.
In other words, the effect of transactions from investment of equity shares in company gets its real time value from various Assets acquired/ disposed & liabilities paid / taken over. The value that appear in balance sheet is the face value of shares. So to know correct value as on date we take real time figures of Assets & Outsiders Liabilities.
I can give you an example from your life which is true to understand intrinsic value concept. See a person who writes B.com from some tom n d**k University by mere presentation and just beating around the bush to fill pages is like a share having only face value. Similarly a candidate evaluated on ICAI benchmark is the real value of that candidate or the value is intrinsic(real strength). This is just for explanation , I feel it is apt example. If anyone is offended, then No Sorry as its the harsh reality..
3---- The answer lies in 1st reply itself.
Hope you understood.
