Despite posting some strong earnings, the market for China Transinfo Technology Co., Ltd's (SZSE:002373) stock hasn't moved much. We did some digging, and we found some concerning factors in the details.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that China Transinfo Technology's profit was reduced by CN¥15m, due to unusual items, over the last year. It's never great to see unusual items costing the company profits, but on the upside, things might improve sooner rather than later. We looked at thousands of listed companies and found that unusual items are very often one-off in nature. And, after all, that's exactly what the accounting terminology implies. If China Transinfo Technology doesn't see those unusual expenses repeat, then all else being equal we'd expect its profit to increase over the coming year.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that China Transinfo Technology received a tax benefit which contributed CN¥94m to the bottom line. This is of course a bit out of the ordinary, given it is more common for companies to be paying tax than receiving tax benefits! The receipt of a tax benefit is obviously a good thing, on its own. And given that it lost money last year, it seems possible that the benefit is evidence that it now expects to find value in its past tax losses. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. In the likely event the tax benefit is not repeated, we'd expect to see its statutory profit levels drop, at least in the absence of strong growth. 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 China Transinfo Technology's Profit Performance

In the last year China Transinfo Technology 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. But on the other hand, it also saw an unusual item depress its profit. Based on these factors, we think it's very unlikely that China Transinfo Technology's statutory profits make it seem much weaker than it is.
