See Note 13 for a discussion of the dividend declared during the second quarter of 2014. Future dividends will be subject to the approval of the Company's board of directors and will depend upon the Company’s results of operations, financial condition, business prospects, capital requirements, contractual restrictions, any potential indebtedness the Company may incur, restrictions imposed by applicable law, tax considerations and other factors that the Company’s board of directors deems relevant. In addition, the Company’s ability to pay dividends on its common stock will be limited by restrictions on the Company’s ability to pay dividends or make distributions to its stockholders and on the ability of subsidiaries to pay dividends or make distributions to the Company, in each case, under the terms of current and any future agreements governing the Company’s indebtedness.

On January 1, 2014, the first offering period under the Company's Coworker Stock Purchase Plan (the “CSPP”) commenced. The CSPP provides the opportunity for eligible coworkers to acquire shares of the Company's common stock at a 5% discount from the closing market price on the final day of the offering period. There is no compensation expense associated with the CSPP.

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. The Company did not receive any proceeds from the sale of shares in the secondary public offering or upon the exercise of the overallotment option.

On March 12, 2014, the Company completed a secondary public offering, whereby certain selling stockholders sold 11,500,000 shares of common stock, including 1,500,000 shares of common stock sold to the underwriters of the secondary public offering on the same date pursuant to the underwriters' exercise in full of the overallotment option granted to them in connection with the secondary public offering. The Company did not receive any proceeds from the sale of shares in the secondary public offering or upon the exercise of the overallotment option. Secondary-offering related expenses of $0.4 million were included within selling and administrative expenses in the consolidated statement of operations for the three months ended March 31, 2014.

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.
