The Impact Of Unusual Items On Profit

Importantly, our data indicates that Flex's profit was reduced by US$130m, due to unusual items, over the last year. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. 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. Assuming those unusual expenses don't come up again, we'd therefore expect Flex to produce a higher profit next year, all else being equal.

An Unusual Tax Situation

Just as we noted the unusual items, we must inform you that Flex received a tax benefit which contributed US$150m to the bottom line. It's always a bit noteworthy when a company is paid by the tax man, rather than paying the tax man. We're sure the company was pleased with its tax benefit. 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.

Our Take On Flex's Profit Performance

In the last year Flex 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. Having said that, it also had a unusual item reducing its profit. Given the contrasting considerations, we don't have a strong view as to whether Flex's profits are an apt reflection of its underlying potential for profit.
