This is the case, for example, when the acquirer guarantees the market price of equity or debt
instruments issued as part of the cost of the business combination and is
required to issue additional equity or debt instruments to restore the
originally determined cost. In such cases, no increase in the cost of the
business combination is recognised. In the case of equity instruments, the
fair value of the additional payment is offset by an equal reduction in the
value attributed to the instruments initially issued
