(1) | Shares related to unvested share-based payment awards we included in our basic and diluted share counts are 224,662 and 251,525 for the three and six months ended June 30, 2013, respectively compared to 76,500 and 169,209 shares for the three and six months ended June 30, 2012, respectively.
(2) | The effect of dilutive options is shown only for informational purposes where we are in a net loss position. In such situations, the effect of including outstanding options and restricted stock would be anti-dilutive, and they are thus excluded from all loss period calculations.
