Allotment and refund obligations require timely electronic allotment and refunds, with interest payable for delayed action. Regulation 205 requires issuers to dispatch letters of allotment simultaneously and, if letters of regret cannot be issued at the same time, publish a media notice the morning after dispatch. Issuers and lead managers must allot securities and refund or unblock application monies within Board specified periods, with lead managers ensuring electronic allotment, credit and refunds. If allotment or refunds are delayed beyond the stipulated period, the issuer must pay interest as disclosed in the offer document and lead managers must ensure such payment.
