Nigeria bourse set to make history as worlds 57th demutualised exchange

I think there may be a slight mistake in your statement. Nigeria's stock exchange, the Nigerian Stock Exchange (NSE), is already a demutualized exchange, not set to become one.

Demutualization is the process of converting a mutual organization, such as a stock exchange, into a publicly traded company. This allows the exchange to raise capital, increase its transparency, and improve its governance.

The Nigerian Stock Exchange (NSE) demutualized in 2015, when it converted from a non-profit organization to a publicly traded company, listed on the NSE itself. This made it the first stock exchange in West Africa to demutualize.

As a result, the NSE is already a demutualized exchange, and it is not set to become the 57th demutualized exchange in the world.
