[1] On October 1, 2009, all of the shares of QLT USA, Inc. ("QLT USA") were sold to TOLMAR Holding, Inc. ("Tolmar") for up to an aggregate $230.0 million, plus cash on hand of $118.3 million. The purchase price included contingent consideration of $200.0 million which had a fair value of $156.2 million on October 1, 2009, representing a non-cash investing activity. During the three months ended June 30, 2011, proceeds received on collection of the contingent consideration totalled $7.4 million (2010 - $8.0 million). Approximately $4.6 million (2010 - $5.5 million) of the proceeds were included within cash provided by investing activities. The remaining $2.8 million (2010 - $2.5 million) of the proceeds were recorded in the Statement of Operations as the fair value change in contingent consideration and were therefore reflected in the net (loss) income line item within cash used in operating activities. During the six months ended June 30, 2011, proceeds received on collection of the contingent consideration totalled $18.6 million (2010 - $18.3 million). Approximately $13.5 million (2010 - $13.3 million) of the proceeds were included within cash provided by investing activities. The remaining $5.1 million (2010 - $5.0 million) of the proceeds were recorded in the Statement of Operations as the fair value change in contingent consideration and were therefore reflected in the net (loss) income line item within cash used in operating activities
