Operating Revenue Or Not?

Most companies divide classify their revenue as either 'operating revenue', which comes from normal operations, and other revenue, which could include government grants, for example. Where possible, we prefer rely on operating revenue to get a better understanding of how the business is functioning. Importantly, the non-operating revenue often comes without associated ongoing costs, so it can boost profit by letting it fall straight to the bottom line, making the operating business seem better than it really is. Notably, BOC Aviation had a significant increase in non-operating revenue over the last year. In fact, our data indicates that non-operating revenue increased from US$123.4m to US$226.9m. The high levels of non-operating revenue are problematic because if (and when) they do not repeat, then overall revenue (and profitability) of the firm will fall. In order to better understand a company's profit result, it can sometimes help to consider whether the result would be very different without a sudden increase in non-operating revenue.

The Impact Of Unusual Items On Profit

As well as that spike in non-operating revenue, we should also consider the US$284m boost to profit coming from 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. And that's as you'd expect, given these boosts are described as 'unusual'. 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).

Our Take On BOC Aviation's Profit Performance

In the last year BOC Aviation's non-operating revenue really gave it a boost, but not in a way that is necessarily going to be sustained. 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 and everything else is equal. Considering all this we'd argue BOC Aviation's profits probably give an overly generous impression of its sustainable level of profitability.
