Loss per share
Note 5: Loss per share
The Company is required to present basic income (loss) per share and diluted income (loss) per share in its consolidated statements of operations. Basic income (loss) per share amounts are computed by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted income (loss) per share reflects additional common shares that would have been outstanding if potentially dilutive common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options and are determined using the treasury stock method. The Company is also required to provide a reconciliation of the numerator and denominator used in the computation of both basic and diluted loss per share.
The following is information about the computation of loss per share for the three and six months ended June 30, 2011 and 2010:
