This means that the results for this quarter are not necessarily indicative of future quarters or full year results given the seasonality of our business.         Our interim financial statements on the previous pages reflect all adjustments that management believes are necessary for the fair statement of the results of operations for the interim periods presented. These adjustments are of a normal recurring nature.         We have evaluated events or transactions that occurred after September 30, 2009 for inclusion in these financial statements through November 6, 2009, the date these financial statements were issued.
