able common stock is calculated by dividing the net loss, adjusted for income or loss on marketable securities attributable to common stock subject to possible redemption, by the weighted-average number of non-redeemable common stock outstanding for the period, basic and diluted.

When calculating its diluted net loss per share, the Company has not considered the effect of (i) the incremental number of shares of common stock to settle warrants sold in the Offering and Private Placement, as calculated using the treasury stock method and (ii) the shares issued to Mr. Weightman subject to forfeiture representing 5,000shares of common stock underlying a restricted stock award for the period it was outstanding. Since the Company was in a net loss position during the period after deducting net income attributable to common stock subject to redemption, diluted net loss per common share is the same as basic net loss per common share for the periods presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.

Accordingly, net loss per common share, basic and diluted, is calculated as follows:
