Unilever's Dutch shareholders have agreed to the company's plans to become 100 percent British, the food group announced Monday.
Next month, British shareholders have to consider the plans.
Unilever is currently still partly Dutch and partly British.
The company, which produces Magnum ice creams, Calvé peanut butter and Cup-a-Soup, wants to get rid of this so-called dual structure.
This should make it easier for Unilever to make large purchases or sell parts.
The main offices of the company's major competitors are located in only one country.
For example, in the event of a takeover, Unilever's current dual structure poses problems, making the group less flexible.
If everything goes according to plan, the group will switch to the new structure in the weekend of 21 and 22 November.
For this, both the Dutch and the British shareholders must have agreed.
On Monday it became clear that more than 99 percent of Dutch shareholders are happy with the plan.
The British must decide on October 12 whether to agree.
If they later vote against, the change will not go through.
GroenLinks wants to impose a fine on Unilever
Even if the British do give permission, it is not yet 100 percent certain that the dual structure will go overboard.
An additional hurdle is looming from Dutch politics.
Opposition party GroenLinks does not like it that large Dutch companies want to relocate their head offices and wants to impose a fine on such a departure.
In the case of Unilever, this fine could amount to an amount of 11 billion euros.
Earlier, the company said that the transition to a fully British structure has been canceled.
On Friday, GroenLinks made it clear that the fine must be coughed up by the shareholders and not by the company itself.
This did not affect the vote, as shareholders had to vote on Wednesday, September 16.
Probably few consequences for employment in the Netherlands
The proposed change will probably have little or no consequences for employment in the Netherlands.
The office in Rotterdam, which now serves as one of the company's two headquarters, will continue to exist and the employees can continue to work there.
The location will no longer function as a head office.
The company also remains listed on both the London and Amsterdam stock exchanges.
However, the company is then no longer a public limited company (NV), but exclusively a PLC (public limited company, the British legal counterpart of the Dutch NV).
This does have consequences for the Dutch treasury.
If the transition goes ahead, the group will only pay profit tax in the United Kingdom and no longer in the Netherlands.
The income from dividend tax will then also be lost.
