6. Per Common Share Data

We calculate basic earnings per common share data using the weighted average number of common shares outstanding during the period. Diluted per share data reflects the potential dilution that would occur if common stock equivalents were exercised or converted to common stock but only to the extent that they are considered dilutive to our earnings. The following table is a reconciliation of basic and diluted per share data for the following periods (dollars in thousands, except per share amounts):

For the three and six month periods ended June 30, 2011 and 2010, we excluded all outstanding stock options and restricted stock awards from the computation of our diluted earnings per share because the effect of these share-based awards was antidilutive due to our net loss. For the three and six months ended June 30, 2011, the total number of outstanding options and restricted stock awards that were antidilutive was 668,531 and 400,877, respectively. For the three and six months ended June 30, 2010, the total number of outstanding options and restricted stock awards that were antidilutive was 614,228 and 505,771, respectively.
