Warrants, options and convertible loans, in plain words.
What each of them is, what happens in real life step by step, and what you enter in aktiebok.io at each step.
In short
None of these are shares. A share register lists shares and who holds them. A warrant, an option or a convertible loan is a right to get shares later, so it is not in the register, and the law does not ask for it there. The register gets a new line on the day the right is used and shares are handed out.
aktiebok.io keeps warrants and options beside the register, so that the cap table can answer the question every investor asks: who would own what if all of it were used. That view is called fully diluted.
- A right to subscribe for new shares at a set price, issued by the company
- Investors, founders, key people
- Usually the market value of the warrant
- Yes
- A programme, shown fully diluted
- Only the shares, from the day they are allotted
- A promise in an agreement between the company and an employee
- Employees
- Nothing
- No
- A programme, shown fully diluted
- Only the shares, from the day they are allotted
- A loan that can be swapped for shares
- Lenders, often existing owners before a round
- The loan amount
- Yes, when it is a konvertibel in the law's sense
- Nothing; it is planned in the simulator
- Only the shares, from the day of conversion
In aktiebok.io: six things to do
A programme is entered once, with its terms. After that you only move its warrants or options. Four of the six things to do are under Add entry, in the group Warrants & options; the two done less often are under More entry types.
- New programme
- The kind, the terms once, how many in all, and the holders with how many each.
- Give out
- To a holder, out of what is unallocated.
- Take back
- From a holder, back to unallocated. One line on the form says they were cancelled instead.
- Exercise
- A holder's warrants or options become shares, in the holder's name.
- Transfer warrants
- Warrants from one holder to another. Under More entry types.
- Cancel units
- The board cancels what is unallocated. Under More entry types.
Each of them is an entry in a draft: you review it, in words and in figures, and nothing is registered until you confirm. Each stays in the History under the same name.
What the cap table then shows is in The cap table and dilution, and what is filed with Bolagsverket in Filing with Bolagsverket.
Teckningsoptioner
In plain words. The company promises that the holder may subscribe for new shares later, at a price set today. If the company has grown, that price is a bargain and the holder uses the right. If not, the holder lets it run out.
In real life, and in aktiebok.io
1 000 000 shares. The meeting issues 50 000 warrants at 40 kr per share, to be used by 30 June 2029. Elin Berg takes 30 000 and Omar Lind 20 000.
- The share register is unchanged: 1 000 000 shares.
- The cap table, fully diluted, shows 1 050 000, with Elin and Omar on their own rows.
- In June 2029 Elin uses hers. The register gets 30 000 new shares in her name, and the company gets 1 200 000 kr.
- Omar does not use his. After 30 June they are gone from the fully diluted view, with no entry made.
Personaloptioner, and the kvalificerade kind
In plain words. The company promises an employee, in an agreement, the right to get shares later at a set price, usually on the condition that they stay for some years. The employee pays nothing for the promise.
Kvalificerade personaloptioner (KPO, in English QESO) are the same thing arranged to meet the conditions of a tax rule for young, small companies, which removes the tax on the benefit when the options are used. Whether a programme meets those conditions is a question for the company's adviser and Skatteverket; a register cannot tell. In aktiebok.io both are entered as Employee options.
The part that confuses everyone. An option is only a promise. To be sure the shares can be delivered years later, most companies issue warrants to themselves when the programme starts and keep them in store. When an employee uses options, the company hands over the same number of warrants and the employee uses them at once to subscribe for shares. The other way is for a general meeting to decide on a new issue to the employee when the time comes, with no warrants at all.
In aktiebok.io you do not have to think about that. You enter one thing, the programme: how many options the meeting decided in all, and who has been promised how many. What is not yet promised to anyone shows as one row, Unallocated. If the company holds warrants in store, that row is them. You never enter the stored warrants separately, so nothing is counted twice.

Fully diluted is what the programme adds on top of the shares. It moves only when options become shares or the programme is made smaller. Giving options to a person only moves them from Unallocated to that person's row.
Vesting (earning the options over time) is in the option agreement, with its rules for someone who leaves. aktiebok.io does not calculate it. When the agreement says options are lost, you take them back.
Employee options are personal. The Transfer warrants form lists programmes of warrants only. When options pass from one employee to the next, take them back and give them out again.
Convertible loans
In plain words. Someone lends the company money, with the idea that the loan becomes shares instead of being repaid, usually at the next funding round and often at a discount to the round's price.
Two things go by this name.
- A konvertibel in the law's sense is issued by a decision of the general meeting and filed with Bolagsverket within six months, like warrants. The lender has a right to swap the claim for shares on the terms decided.
- A loan agreement with a promise to convert is an ordinary loan. Nothing is registered. At the next round the general meeting decides on a new issue to the lender, paid by setting off the loan against the price (a kvittningsemission).
Neither is entered as a programme. How many shares a loan becomes is often not known until the round it converts in, and a loan is not in a share register.
In real life, and in aktiebok.io
An owner lends the company 500 000 kr, to convert at the next round at a 20 % discount.
- The round is priced at 50 kr per share, so the loan converts at 40 kr into 12 500 shares.
- Before the round, the simulator shows the round with and without the loan.
- At the round, one Issue entry gives the lender 12 500 shares at 40 kr.
Questions that come up
- Are options and warrants in the share register?
- No. The printed register lists shares only. They show in the cap table's fully diluted columns and in their own list under it, Warrants and options, where you open a programme to see its holders.
- Who can see them?
- Everyone who can read the company's register sees the programmes and who holds what.
- What does "fully diluted" count?
- Every share, plus every share that warrants and options still running would give, including what is unallocated in a programme. Convertible loans are not counted, since they are not entered.
- What is the Unallocated row?
- The warrants or options of a programme that no holder has yet. It is not a shareholder: it has no shares, no votes and no value, and it belongs to no group. It is there so that the fully diluted total is the whole programme.
- When do the new shares count?
- In the register from the day the board allots them. In the share capital from the day Bolagsverket registers them.
- We promised options but have not issued any warrants.
- Enter the programme the same way. How the shares will be delivered does not change what you enter.
- Someone left. Take back or cancel?
- Take back when the warrants or options still exist and can go to someone else: they return to Unallocated and still count fully diluted. Say they were cancelled when the board has cancelled them: they leave the programme for good.
- A holder used warrants in the last days, and we enter it afterwards.
- Enter the Exercise dated on the day the shares were allotted. After the last day you can still enter it, as long as it is dated on or before that day.
- We split the shares, or made a bonus issue.
- Enter the split or the bonus issue and nothing else. Every programme that exists on its date is recalculated, as terms normally say: the number of warrants or options stays, each gives proportionally more or fewer shares, and the price per share changes the other way. The review says what happens to each programme before you confirm, and the programme's own page shows its terms before the change. Do not cancel a programme and enter it again for this.
- We entered a programme wrong.
- Reverse it from History and enter it again, like any entry. Entries that moved its warrants or options are reversed first.
