The Power Of Non-Operating Revenue

At most companies, some revenue streams, such as government grants, are accounted for as non-operating revenue, while the core business is said to produce operating revenue. 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. It's worth noting that BOC Aviation saw a big increase in non-operating revenue over the last year. Indeed, its non-operating revenue rose from US$226.9m last year to US$356.4m this year. 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$286m boost to profit coming from unusual items, over the last year. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And, after all, that's exactly what the accounting terminology implies. 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 its last report BOC Aviation benefitted from a spike in non-operating revenue which may have boosted its profit in a way that may be no more sustainable than low quality coal mining. 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.
