Enhanced Profile
Shareholding percentage rangesShareholdings can now express an ownership range when a registry does not report an exact percentage.
  • CoreShareholderDetail.percentageField is now nullable. When a range applies, percentageField is null and percentageIsRangeField, percentageRangeField, percentageLowerLimitField, and percentageUpperLimitField carry the range.
