As soon as is reasonably practicable after a local government finance report for a financial year has been approved by resolution of the Assembly, the Welsh Ministers shall calculate what sum, if any, falls to be paid to each receiving authority by way of revenue support grant for the year in accordance with the basis of distribution specified in the report as so approved.
The Welsh Ministers may carry out the subsection (1) calculation again at any time before the end of the financial year immediately following the one to which the report relates.
The power under sub-section (2) may only be exercised once and shall not be exercisable after the approval by resolution of the Assembly of any amending report made under section 84L in relation to the local government finance report.
As soon as is reasonably practicable after making a calculation under subsection (1) or by virtue of subsection (2), the Welsh Ministers shall inform each receiving authority to which the report relates of the outcome, so far as relating to it.
