Shareholders' Equity

On July 2, 2013, the Company completed an IPO of 23,250,000 shares of common stock. On July 31, 2013, the Company completed the sale of an additional 3,487,500 shares of common stock to the underwriters of the IPO pursuant to the underwriters' July 26, 2013 exercise in full of the overallotment option granted to them in connection with the IPO. Such shares were registered under the Securities Act of 1933, as amended, pursuant to the Company's Registration Statement on Form S-1, which was declared effective by the SEC on June 26, 2013. The shares of common stock are listed on the NASDAQ Global Select Market under the symbol “CDW.” The Company's shares of common stock were sold to the underwriters at a price of $17.00 per share in the IPO and upon the exercise of the overallotment option, which together, generated aggregate net proceeds of $424.7 million to the Company after deducting underwriting discounts, expenses and transaction costs.

On November 19, 2013, the Company completed a secondary public offering, whereby certain selling stockholders sold 15,000,000 shares of common stock. On December 18, 2013, such selling stockholders sold an additional 2,250,000 shares of common stock to the underwriters of the secondary public offering pursuant to the underwriters' December 13, 2013 exercise in full of the overallotment option granted to them in connection with the secondary public offering.

No shares of preferred stock have been issued or are outstanding as of December 31, 2013. Additionally, the amended and restated certificate of incorporation increased the number of authorized common shares to 1,000,000,000.
