Mr. Bernard Gloster:

A letter of determination is a provision under the Act. Within a certain period of the budget, the Minister issues a determination to the HSE of the parameters of the budget available for 2024 and the policy requirements of the Government of the day in the context of how it is spent. We turn that into a service plan for submission and consideration by the Minister.

It is a formal statutory requirement that tells one exactly how much one has, as opposed to how much one thinks one has.
