Public issue procedures for InvITs refined to restrict anchor investor eligibility and require ASBA-only bidding and electronic platform use. Subscription and bidding mechanics are standardized to an ASBA-only payment mechanism and exclusive use of recognised stock exchanges' electronic bidding platforms. Investors must submit bid-cum-application forms through SCSBs or prescribed intermediaries, who are responsible for uploading bids, stamping and acknowledging applications and submitting them for fund-blocking. Stock exchanges must validate DP/Client/PAN details daily, permit limited on-file modifications to specified fields, provide transparent electronic bidding facilities, and enable investor status viewing and alerts via websites, SMS and email.
