It is possible that actual results and events may differ, possibly materially, from the anticipated results or events indicated in these forward-looking statements. Forward-looking statements are not guarantees of future performance, and we caution you not to place undue reliance on these statements. Forward-looking statements are made only as of the date hereof, and we undertake no obligation to update any forward-looking statements to reflect new information or events or conditions after the date hereof.
