A conversion clause (Swedish: omvandlingsförbehåll) is a provision in the articles of association that allows a share of one share class to be converted to another, for example from an A-share to a B-share. It sets out the conditions and who can request it.
A conversion clause must be shown in the share ledger. When a conversion takes place, the change of class is registered with Bolagsverket. The share ledger must then show which class each share belongs to, since this can affect voting rights.

A transfer restriction is a condition in the articles of association that limits how shares may be transferred.
