Basic net loss per common share is computed by dividing net loss attributable to the Company, decreased in the case of income and increased in the case of loss by dividends declared on preferred stock, by the weighted-average number of common shares outstanding.

The dilutive effect of incremental common shares potentially issuable under outstanding options and warrants and unvested restricted stock is included in diluted earnings per share utilizing the treasury stock method. A reconciliation of basic and diluted common shares used in the computation of per share data follows:
