Why does IFRS 18 treat the operating category as a leftover, and what does that mean for the profit figure most readers look at first? If you are searching for how operating profit works under IFRS 18, the answer starts with a change of habit. You stop asking whether a line feels like trading and start asking what has claimed it already.
Operating as the residual
IFRS 18.52 defines operating by exclusion. An item lands there when no other category takes it. The lesson explains why that definition makes the category a catch-all and why it matters when you meet an unfamiliar line.
A sorting routine you can reuse
We treat the statement of profit or loss as trays for investing, financing, income taxes and discontinued operations, with operating taking the remainder. The order is a teaching device, since the standard defines operating by exclusion without prescribing a sequence of tests.
Watching items leave
Using AmaTrade, a retailer, the lesson follows one income line and one expense line as they test their way out of operating. The point to look for is what each line must show before it leaves, and what happens when it shows nothing.
What the subtotal can and cannot tell you
IFRS 18 para 69 requires operating profit as a subtotal. The lesson is candid about its limits. It says little about how a business is funded, what its cash earned or what tax it paid, and one-off items can sit inside it without being core trading.
Working down the statement
You then build operating profit for AmaTrade and carry it down to profit after tax, with a journal for the tax line. Try predicting each step before you reach it, then compare your reasoning with ours.
What sits outside this lesson
Entities with specified main business activities need a separate assessment, so AmaTrade is not a template for them. Foreign exchange, derivatives and hedging are beyond today’s scope.

Questions about this topic
Why is operating called the residual category in IFRS 18?
IFRS 18.52 defines it by exclusion, so an item is operating when no other category claims it.
Does IFRS 18 require an operating profit subtotal?
Yes. IFRS 18 para 69 requires operating profit to be presented as a subtotal in the statement of profit or loss.
Does the sorting routine work for every entity?
Not without care. Entities with specified main business activities need a separate assessment, so the routine in the lesson suits an entity without one.
