Proportional allotment: retail applicants receive rounded entitlements with minimum application size and lot draw on oversubscription. Allotment on oversubscription is made by computing each retail applicant's entitlement on a proportional basis, dividing shares applied by the category oversubscription multiple, then rounding entitlements to marketable lots or the minimum application size. Entitlements below the minimum are rejected; rounding and category shortfalls create surpluses which are redistributed to other categories. Final successful applicants may be selected by drawal of lots after proportional allocation and rounding adjustments.
