The Impact Of Unusual Items On Profit

For anyone who wants to understand Williams Companies' profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit gained from US$524m worth of unusual items. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. 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. Which is hardly surprising, given the name. 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).
