Our current monthly closing schedule is a 4/4/5 weekly-based cycle for each fiscal quarter, as opposed to a calendar month-based cycle for each fiscal quarter. Prior to January 1, 2011, we utilized a 5/4/4 weekly-based cycle for each fiscal quarter. While the actual dates for the quarter-ends will change slightly each year, we believe that there are not any material differences when making quarterly comparisons. Quarterly and year-to-date computations of per share amounts are made independently; therefore, the sum of per share amounts for the quarters may not equal per share amounts for the year.
