Item 8 determination - Interest on notional balances

The Item 8 determination from 1 April 2017 says:


Interest on notional cash balance means the interest credited to the Housing Revenue Account on notional credit balances attributed to the Housing Revenue Account, the Housing Revenue Account Repairs Account and the Major Repairs Reserve

The previous determination stated:

Interest on notional cash balance means the interest credited to the Housing Revenue Account on notional credit balances attributed to the
Housing Revenue Account, the Housing Repairs Account, unapplied housing capital receipts and the Major Repairs Reserve

We are struggling to find an explanation for the removal of unapplied housing capital receipts. Has anyone else noticed this or found an explanation or guidance anywhere?
