Related to it (I suspect) is that there's been a re-statement of DH14's Revenue and Employee Expenses (both commensurately upwards), and I suspect there has been a re-allocation of some Revenue retained by the self-employed dentists in that year to Stat. Revenue.
The notes to the accounts are limited at the interim, so clarity will have to be garnered from some direct interaction with the company's bean counters.
