Step 2In relation to each of the amounts (“R1” and “R2”) so apportioned to the two tax years, calculate the amounts (“X1” and “X2”) that would be given by the formula if there were separate issues of shares in those tax years.In calculating amounts X1 and X2, apply section 229 if appropriate but do not apply section 226 or 227.Step 3Add amounts X1 and X2 together.The result is the required amount.
