OT66030 - Transferable tax history - TTH allocation on a loss carry back - Total activated TTH amount – subsequent loss-making period

In any loss-making period other than the first loss-making period, the total activated TTH amount is the lower of:

  1. The adjusted activated TTH amount and
  2. The closing balance of the total TTH amount for the immediately preceding period.

The adjusted activated TTH amount is calculated by taking the closing balance of activated TTH for the immediately preceding period and either:

  1. Adding to that amount the additional activated TTH amount, if in the period additional TTH is activated (as a result of the relevant proportion of the decommissioning expenditure attributable to the TTH asset for that period exceeding the tracked profit or loss amount attributable the TTH asset for that period), or
  2. Deducting from that amount the TTH reduction amount, if the tracked profit amount attributable to the TTH asset for that period exceeds the relevant proportion of the decommissioning expenditure attributable to the TTH asset for the period.

If neither of those scenarios applies, the adjusted activated TTH amount is the closing balance of activated TTH for the immediately preceding period, or nil, if the balance is nil or negative.
