Proceeds from a tender offer transaction will be credited into your COL account's cash balance after the cross or settlement date. The cross or settlement date is the day the shares will be transacted. Shareholders will sell their shares and the company would buy the shares at a fixed price. The cash from the selling proceeds will then be given and credited to the respective shareholders. 

Don't worry if your shares have already been debited from your portfolio but no cash proceeds have reflected yet. We are just waiting for the cross  or settlement date to happen and then the proceeds will be credited to your COL account.
