Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our common stock has been listed on the Nasdaq Global Select Market since June 27, 2013 under the symbol "CDW."

Holders

As of February 23, 2021, there were 12 holders of record of our common stock. The number of beneficial stockholders is substantially greater than the number of holders of record because a portion of our common stock is held through brokerage firms.

Dividends

On February 10, 2021, we announced that our Board of Directors declared a quarterly cash dividend on our common stock of $0.400 per share. The dividend will be paid on March 10, 2021 to all stockholders of record as of the close of business on February 25, 2021.

We expect to continue to pay quarterly cash dividends on our common stock in the future, but such payments remain at the discretion of our Board of Directors and will depend upon our results of operations, financial condition, business prospects, capital requirements, contractual restrictions, any potential indebtedness we may incur, restrictions imposed by applicable law, tax considerations and other factors that our Board of Directors deems relevant. In addition, our ability to pay dividends on our common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current and any future agreements governing our indebtedness. For additional information on our cash resources and needs and restrictions on our ability to pay dividends, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" included elsewhere in this report. For additional information on restrictions on our ability to pay dividends, see Note 10 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Issuer Purchases of Equity Securities

On February 7, 2019, we announced that our Board of Directors authorized a $1.0 billion increase to our share repurchase program under which we may repurchase shares of our common stock in the open market through privately negotiated or other transactions, depending on share price, market conditions and other factors. On February 10, 2021, we announced that our Board of Directors authorized a $1.25 billion increase to our share repurchase program.

In March 2020, we elected to temporarily suspend share repurchases as a precautionary measure in light of the COVID-19 pandemic. We made no share repurchases during the second and third quarters of 2020. In November 2020, we resumed our share repurchase program.

Information relating to the Company's purchases of its common stock during the quarter ended December 31, 2020 is as follows:
