A bond with warrants (Swedish: optionslån) is a loan a limited company raises through debt instruments with a right to subscribe for new shares. The right takes the form of warrants, which can often be detached and transferred separately.
When the right is exercised, new shares are subscribed at the set subscription price, and the new owner is entered in the share ledger. Outstanding warrants belong in the cap table as they can cause dilution.
