Early Closings
* New Years' Day (January 1) in 2011 falls on a Saturday. The rules of the applicable exchanges state that when a holiday falls on a Saturday, the preceding Friday is observed unless the Friday is the end of a monthly or yearly accounting period. In this case, Friday, December 31, 2010 is the end of both a monthly and yearly accounting period; therefore the exchanges will be open that day and the following Monday.

** The NYSE, NYSE AMEX and NASDAQ will close trading early (at 1:00 PM ET) on Friday, November 25, 2011 (the day after Thanksgiving).
