Answer: the correct answer is $70000
Explanation: the fair value of the shares given plus the fair value of the contingent consideration is the total amount paid by the buyer which is (20000 shares * $10 price per share) = $200000+$10000= $210000.
The gain of the transaction is registered as the net fair value of the acquiree that is $350000-$70000= $280000 less the sum paid by the Acquirer that is $280000-$210000= $70000.
The $15000 in direct acquisition costs are registered as period expenses and not relevant for the calculation of the gain of the transaction.
