*Due to a technical problem, for 66 trade dates between January 1, 2010 and February 22, 2011, the Threshold Securities Lists published for NYSE, NYSE American and NYSE Arca incorrectly omitted securities that met the requirements for a Threshold Security. The Threshold Securities Lists for those trade dates were republished on February 24, 2011 with corrected information. The affected dates are noted by an asterisk.
