613.This Chapter sets out how two key amounts, the “tested expense amount” and the “tested income amount”, are to be calculated. The “tested expense amount” must be calculated so that, by comparison with the “available amount” dealt with in Chapter 9, it can be determined whether the adjustments provided for by Chapters 3 and 4 are necessary. In calculating the amount of financing income the “tested income amount” is exempted from corporation tax by Chapter 4.
