How Do Unusual Items Influence Profit?

Importantly, our data indicates that Choil Aluminum's profit received a boost of ₩876m in unusual items, over the last year. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. Which is hardly surprising, given the name. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that Choil Aluminum received a tax benefit of ₩932m. This is meaningful because companies usually pay tax rather than receive tax benefits. The receipt of a tax benefit is obviously a good thing, on its own. And since it previously lost money, it may well simply indicate the realisation of past tax losses. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. So while we think it's great to receive a tax benefit, it does tend to imply an increased risk that the statutory profit overstates the sustainable earnings power of the business.

Our Take On Choil Aluminum's Profit Performance

In the last year Choil Aluminum received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. And on top of that, it also saw an unusual item boost its profit, suggesting that next year might see a lower profit number, if these events are not repeated. For the reasons mentioned above, we think that a perfunctory glance at Choil Aluminum's statutory profits might make it look better than it really is on an underlying level. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks.
