An A-share (Swedish: A-aktie) is a share class that usually has higher voting power than the company's other shares, most often B-shares. A common arrangement is that an A-share carries ten votes and a B-share one vote. The rights that apply are set out in the articles of association.
A-shares often let founders or long-term owners keep influence when the company raises capital. The share ledger must show which share class each share belongs to, so the distribution of votes between owners can be followed.

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