A split, or division of shares, means that each share in a limited company is divided into several shares. The number of shares increases while the share capital is unchanged, which lowers the quota value per share.
A split can make the share easier to handle, for example ahead of a new share issue or to facilitate a transfer of shares. Owners' stake in the company is unaffected. The opposite is a reverse split. The decision is made by the general meeting and recorded as a share ledger event.

A reverse split merges several shares into fewer, with a higher value per share.
