DAVID SEYMOUR (Leader—ACT): Mr Chairman, thank you for that clarification. Just on the second part of this bill, the minimum family tax credit increase, I was under the impression that this was in order to create some sort of, I guess, co-linearity with the benefit changes that were made during last April's lockdown or last March's lockdown. You've said in passing, in your speech, that that was not the reason, that it was actually to do with an adjustment to abatement rates. Can you please explain abatement rates of what exactly, and when were those changes made?
