The weighted number of shares and dilutive potential shares for the year ended December 31, 2013 includes the conversion of the first tranche of 659,926 shares of Performance Stock to common stock. The first tranche of Performance Stock was included in the weighted number of shares and dilutive potential shares for the year ended December 31, 2012, at the time the performance target was achieved in December 2012. The weighted number of shares for the year ended December 31, 2011, does not include the dilutive effect of the first tranche of Performance Stock since the revenue target was not achieved at that time. The weighted number of shares and dilutive potential shares for the years ended December 31, 2013, 2012 and 2011 do not include the Performance Stock related to the second tranche, which will be included in the Company's share count at the time the revenue target is achieved. If the revenue target for the second tranche is not achieved, the contingent convertible preferred shares in that tranche will be canceled.
