Should have read: "If you rely on the incorrect numbers in the Q1 2011 filing you are likely to believe that Yellows revenues have not fallen much versus Q1 2010 a year ago. If you look at the real original reported numbers from Q1 2010, the Q1 2011 income statement shows a very substantial shrinkage of revenues."
They had not closed the sale for Trader at the time of that release, so looking at financials without reading the full text of the release there was no reason to believe they would restate prior quarters.
Now that I read the text of the release and not just the financials, yes I see they did restate current and prior quarters by taking out Trader. It's very unusual for a company to restate like that prior to actually closing the sale of the asset.
