An integrated care board must exercise its functions with a view to ensuring that expenditure incurred by the board in a financial year does not exceed the sums received by it in that year.
NHS England may by direction—
specify descriptions of expenditure that are, or are not, to be treated for the purposes of this section as expenditure incurred by an integrated care board, or expenditure incurred by it in a particular financial year;
specify descriptions of sums that are, or are not, to be treated for the purposes of this section as having been received by an integrated care board, or as having been received by it in a particular financial year;
provide for sums received by an integrated care board under section 223G in a year but not spent to be treated for the purposes of this section as expenditure incurred by it in a particular financial year.
For the purposes of this section any sum allotted to an integrated care board for a year under section 223G is to be treated as received by it in that year (subject to any direction under subsection (2)(b)).
