Common stock outstanding abstract         Our outstanding shares of common stock typically include shares that are deemed delivered under US GAAP. Shares that are deemed delivered currently include shares that have vested, but have not yet been delivered, under tax-deferred equity awards, as well as shares purchased under the ESPP where actual transfer of shares normally occurs a few days after the completion of the purchase periods. There are no voting rights for shares that are deemed delivered under US GAAP until the actual delivery of shares takes place. There are currently 200,000,000 shares of common stock authorized for issuance.
