Today's earnings release did not elaborate on any details of the search process, but investors will surely be listening in on the company's conference call this morning to hear any news. This year "continues to be the most important and most productive year in lululemon's history," Day said in the earnings statement. "We have not only worked our way back from the black luon setback, but have also added very talented people in important functions and have taken major steps forward on a number of key fronts including the expansion of our international and men's businesses and many logistical initiatives." "We are well on our way to finishing 2013 as a much stronger company than when the year began. I am confident that the leadership currently in place coupled with a new CEO will have tremendous success leveraging the platform for growth," Day said. -- Written by Laurie Kulikowski in New York.
