Equity [Abstract] |
Stockholders' Equity | Stockholders' Equity Stock Repurchase Program In May 2017, our Board of Directors authorized, subject to regulatory approval, expansion of our stock repurchase program by an additional $150 million. We sought and received regulatory approval during the second quarter of 2019 and entered into an accelerated share repurchase agreement for $100 million in May 2019. In August 2019, we completed final settlement of shares purchased under this agreement, receiving in total approximately 2.1 million shares at an average repurchase price of $48.26. As of June 30, 2020, we have an authorized $50 million remaining under our current stock repurchase program for any additional repurchases. Walmart Restricted Shares On January 2, 2020, we issued Walmart, in a private placement, 975,000 restricted shares of our Class A Common Stock. The shares vest in equal monthly increments through December 1, 2022. Walmart is entitled to voting rights and participate in any dividends paid from the issuance date on the unvested balance, and therefore, the total amount of restricted shares issued are included in our total Class A shares outstanding. As of June 30, 2020, there were 812,502 unvested shares outstanding. The estimated grant-date fair value of the restricted shares is recorded as a component of stock-based compensation expense over the related period we expect to benefit under our relationship with Walmart.
