I have found companies with multiples PSC with ownership of shares – 75% or more.
An example may help:https://beta.companieshouse.gov.uk/company/01216730/persons-with-significant-control
This is normal?In this way the sum of shares (although it is not possible to quantify accurately) surpasses 100%.
This could be explained by joint share holders. For example, 10 people could all own joint shareholding(s) that accounts for 75% of the company shares.Hope that helps.
@MArkWilliams thanks for the explanation.
