giving away assets in exchange for equity interest

sir i understand that when assets are contributed by entities in exchange for equity interest in Joint Venture or Associate, then the contributor recognises a portion of gain/loss accruing to other investors, in the contributor’s individual financial statements.

case 1: However, what am not clear with is, when an entity contributes assets in exchange for a CONTROLLING stake in another company then how should gain/loss on transfer be recognised in the individual financial statements of the co which is intending to become parent? full gain/loss? or only NCI %?

case 2: what about situation when a transfer is done in a joint operation? full gain/loss or only that accruing to other joint operators?
