2. EARNINGS PER SHARE

The number of shares and earnings per share data (“EPS”) for all periods presented are based on the historical weighted-average shares of common stock outstanding. EPS is computed using the two-class method. The two-class method determines EPS for common stock and participating securities according to dividends and dividend equivalents and their respective participation rights in undistributed earnings. The Company’s convertible preferred stockholders were entitled to receive dividends in the event dividends on the Company’s common stock were declared. As a result, the shares of the Company’s convertible preferred stock were deemed to be participating securities.

In connection with the IPO, all preferred stock mandatorily converted to common stock on a 1:1 basis.

Basic EPS of common stock was computed by dividing net income, less the undistributed earnings allocated to participating interests, by the weighted-average number of shares of common stock outstanding for the period. Due to the issuance of the series X preferred stock in 2010, the basic EPS was computed by dividing net income, less the original investment of $5,000 in series X preferred stock and annualized 20.0% preferred return and the undistributed earnings allocated to participating interests, by the weighted-average number of shares of common stock outstanding for the period. The original investment in series X preferred stock and the 20.0% preferred return was required to be paid to series X preferred stockholders prior to any payment of dividends to the common stockholders. For the year ended December 26, 2010, after adjusting net income for the original investment in and the preferred return on the series X preferred stock, there was no income remaining to be allocated to the Company’s common stock or participating interests.

Diluted EPS of common stock is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential shares of common stock equivalents outstanding during the period using the treasury stock method for dilutive options and the if converted method for dilutive convertible preferred stock. The numerator is net income less the preferred return and undistributed earnings on the series X preferred stock as this series of preferred stock was anti-dilutive using the if converted method. Options to purchase 50,026 shares of common stock for the year ended December 26, 2010, were outstanding but not included in the computation of diluted net EPS because their inclusion would have an anti-dilutive effect. For all periods presented undistributed earnings allocated to participating interests related to the series A preferred stock and series B preferred stock were not deducted from net income for purposes of calculating diluted earnings per share because the diluted earnings per share gave effect to the conversion of this preferred stock into common stock as of the beginning of the year. For the year ended December 26, 2010, the series A preferred stock and the series B preferred stock were antidilutive as a result of the net loss available to common stockholders.

The computation of basic and diluted earnings per share is as follows:
