Shareholders' Equity

In June 2013, the Company’s Board of Directors and the Company's sole shareholder at that time, CDW Holdings, approved the reclassification of the Company’s Class A common shares and Class B common shares into a single class of common shares and a 143.0299613-for-1 stock split, effective immediately. The par value of the common shares was maintained at $0.01 per share. All references to common shares and per share amounts in the accompanying consolidated financial statements have been adjusted to reflect the reclassification and stock split on a retroactive basis.

In June 2013, the Company amended and restated its certificate of incorporation to authorize the issuance of 100,000,000 shares of preferred stock with a par value of $0.01. No shares of preferred stock have been issued or are outstanding as of June 30, 2013. Additionally, the amended and restated certificate of incorporation increased the number of authorized common shares to 1,000,000,000.

On July 2, 2013, the Company completed an IPO of its common shares. See Note 13 for additional discussion of the Company's IPO.
