In applying this step, ignore any lack of profits of the claimant company from which deductions could have been made as mentioned in section 137(1).\nStep 2 Deduct from the amount arrived at under step 1 the amount of any group relief actually given to the claimant company under Part 5 in relation to losses or other amounts within section 99(1) which the surrendering company had for the specified loss-making period.\nStep 3 Multiply the amount arrived at following step 2 by the fraction in subsection (2).\nStep 4 Deduct from the amount arrived at following step 3 any group relief for carried-forward losses previously given to the claimant company on claims under section 188CC which are related to the current claim.\n(2) The fraction referred to in step 3 is—\nABwhere—\nA is the sum of the losses or other amounts within section 99(1)(a), (c), (e), (f) and (g) which the surrendering company had for the specified loss-making period, and\nB is the sum of the losses or other amounts within section 99(1) (a) to (g) which the surrendering company had for the specified loss-making period.\n(3) References in subsection (2) to losses or other amounts are references to losses or other amounts only in so far as they were eligible for surrender under Chapter 2 of Part 5.\n(4) A claim under section 188CC is related to the current claim if the surrendering company and the specified loss-making period are the same in relation to both claims.",
