When shares are forfeited, the share capital account is debited by the amount called up on the shares. The credited entries include:
- Calls in Arrears account for unpaid amounts, and
- Share Forfeiture account for amounts already received.
The securities premium account, if any, is not reversed during forfeiture because it represents a legitimate premium received on the shares and is not affected by forfeiture. Thus, both the Assertion (A) and Reason (R) are correct, and Reason (R) correctly explains the Assertion (A).
