Hi Carla
Table 2a relates to Company title properties where instead of a person having separate title against a lot in a strata plan which in turn has a unit entitlement they buy shares in a Company.
Holding shares in the Company allows them to occupy a part of a building with one or more persons who also hold shares in the company.
The VG is requesting the share entitlement for each shareholder in the Company as unlike strata plans they do not know how the shares are allocated against each property.
If you want to know more about company title have a look at Section 547 of the LGA 1993.
Hope this helps.
