See Note 20 for a discussion of the dividend declared during the first quarter of 2015. 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 ability of subsidiaries to pay dividends or make distributions to the Company, in each case, under the terms of certain current and future agreements governing the Company’s indebtedness.

On November 6, 2014, the Company announced that its Board of Directors approved a $500.0 million share repurchase program effective immediately under which the Company may repurchase shares of its common stock in the open market or through privately negotiated transactions, depending on share price, market conditions and other factors. The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and repurchases may be commenced or suspended from time to time without prior notice. As of the date of this filing, no shares have been repurchased under the share repurchase program.

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.

The Company has completed the following secondary public offerings, whereby certain selling stockholders sold shares of common stock to the underwriters. The Company did not receive any proceeds from these sales of shares.

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 December 31, 2014. Additionally, the amended and restated certificate of incorporation increased the number of authorized common shares to 1,000,000,000.
