Preformed Line Products Company's (NASDAQ:PLPC) earnings announcement last week didn't impress shareholders. Despite the soft profit numbers, our analysis has optimistic about the overall quality of the income statement.

The Impact Of Unusual Items On Profit

For anyone who wants to understand Preformed Line Products' profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit was reduced by US$12m due to unusual items. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And that's hardly a surprise given these line items are considered unusual. Assuming those unusual expenses don't come up again, we'd therefore expect Preformed Line Products to produce a higher profit next year, all else being equal.
