(A)
The net effect of the Recapitalization includes amounts attributable to the Series C Offer and the Series D Exchange and was calculated in accordance with applicable Earnings per Share guidance. The Series C Offer amount is calculated as the difference between (1) the fair value of the consideration transferred to the holders of the Series C Preferred Stock and (2) the carrying amount of the Series C Preferred Stock. The Series D Exchange amount consists of the excess of (1) the fair value of all securities and other consideration transferred by the Company to the Series D Holders over (2) the fair value of securities issuable pursuant to the original conversion terms. See Note 14 to the condensed consolidated financial statements for further details.
Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share
The following weighted-average stock options to purchase shares of Common Stock were outstanding during each period presented, but were not included in the computation of diluted earnings (loss) per share because the number of shares assumed to be repurchased, as calculated was greater than the number of shares to be obtained upon exercise, therefore, the effect would be antidilutive (in thousands, except exercise prices):
