National Insurance Contributions Bill

I greatly appreciate the Minister giving way. Before he sits down, will he or one of his colleagues answer on the financial costs of the employment allowance contained in the Treasury documents? What impact on the take-up of tax credits were included in the estimate of £1.25 billion impact on the Exchequer in 2014 through to £1.7 billion in 2017-18? I do not expect the Minister to have those numbers to hand, but if his colleagues could reply to that later, or send me a note, I would appreciate it.
