Basic loss per share is computed by dividing net loss by the weighted-average number of shares of Class A and Class B common stock outstanding, but excluding shares of common stock subject to repurchase for the period. The number of common stock shares subject to repurchase was determined prospectively from the date of the Stock Restriction Agreement entered into by the Company and David Hung, M.D. Diluted loss per share reflects the potential dilution that could occur if the stock options to issue common stock were exercised. The Company had a net loss in all periods presented thus the dilutive net loss per common share is the same as the basic net loss per common share as the effect of any options or conversions is anti-dilutive.

The earnings per share amounts are the same for the different classes of common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or liquidation.
