2.For households where more than one member is working, the assumption is made that the household's total earnings are 500, 700, 1,000 and 2,000 per cent. of average gross male earnings.

5.All National Insurance Contributions are at the Class I standard rate for employment not contracted out of the state additional (earnings related) pension scheme.
