A C-share (Swedish: C-aktie) is a share class whose rights are set out in the articles of association. C-shares often carry lower voting power than A-shares, for example one tenth of a vote, and sometimes a limited right to dividends. They are used, among other things, in connection with incentive programs.
The letter itself says nothing about the rights; the articles of association decide. The share ledger must show which share class each share belongs to, so that votes and holdings can be calculated correctly.

Share class refers to different types of shares in a company, e.g. A and B shares, with different rights.
