Temporary recruitment of audit partner

Hello tutor, I don’t understand the answer of BPP kit.

In particular, the safeguard of management decision making threat. The answer is extracted:

In order to reduce this risk, the use of a less senior member of staff with relevant experience of the flotation process could be proposed and make it clear in the contract that they are not able to make decisions for Gull Co and that decision making will always remain their responsibility. Alternatively, it could be recommended that Gull Co recruit the assistance of either the management or transaction advisory services team to assist them with the flotation as a separate engagement, thus circumventing the ethical threats identified.

My question: What is the flotation process ? To be honest I don’t understand what it is. Thanks tutor a lot !
