Shares of common stock reserved for issuance upon the conversion of our convertible preferred stock were proportionately reduced and the respective conversion prices were proportionately increased. All references to shares in the accompanying consolidated financial statements and the notes thereto, including but not limited to the number of shares and per share amounts, unless otherwise noted, have been adjusted to reflect the reverse stock split retroactively.
