The Impact Of Unusual Items On Profit

Importantly, our data indicates that L.B. Foster's profit received a boost of US$1.4m 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. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. And that's as you'd expect, given these boosts are described as 'unusual'. If L.B. Foster doesn't see that contribution repeat, then all else being equal we'd expect its profit to drop over the current year.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that L.B. Foster received a tax benefit which contributed US$29m 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 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. 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. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On L.B. Foster's Profit Performance

In its last report L.B. Foster received a tax benefit which might make its profit look better than it really is on a underlying level. 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 L.B. Foster's statutory profits might make it look better than it really is on an underlying level.
