As of June 30, 2013, 809,772 shares of Class A common stock issued to Walmart were subject to our repurchase right. Basic and diluted EPS for these shares were the same as basic and diluted EPS for our Class A common stock for the three and six-month periods ended June 30, 2013 and June 30, 2012.

We excluded from the computation of basic EPS all shares issuable under an unvested warrant to purchase 4,283,456 shares of our Class B common stock, as the related performance conditions had not been satisfied.

For the periods presented, we excluded all shares of convertible preferred stock and certain stock options outstanding, which could potentially dilute basic EPS in the future, from the computation of diluted EPS as their effect was anti-dilutive. The following table shows the weighted-average number of anti-dilutive shares excluded from the diluted EPS calculation:
