Allocation in non-book-built issues: retail investors must receive a majority share, with remainder allocated and reallocation rules. The amendment mandates that in issues other than by book building the net offer must allocate a minimum fifty per cent to retail individual investors, with the balance to other individual and institutional applicants; unsubscribed portions may be reallocated between categories, and if retail entitlement on a proportionate basis exceeds fifty per cent they receive that higher share.
