Common Stock

The Company's common stock is listed on Cboe BZX and the NASDAQ Global Select Market under the trading symbol CBOE. As of January 31, 2018, there were approximately 186 holders of record of our common stock.

The following table sets forth the high and low sales prices by quarter for shares of our common stock as reported on BZX and NASDAQ and cash dividends declared per quarter:

Dividends

Each share of common stock, including restricted stock awards and restricted stock units, is entitled to receive dividend and dividend equivalents, respectively, if, as and when declared by the board of directors of the Company.

The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's board of directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our board of directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends.

As a holding company, the Company's ability to declare and continue to pay dividends in the future with respect to its common stock will also be dependent upon the ability of its subsidiaries to pay dividends to it under applicable corporate law.

Share Repurchase Program

In 2011, the board of directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and approved additional authorizations of $100 million in each of 2012, 2013, 2014, 2015, and February 2016 for a total authorization of $600 million. The program permits the Company to

purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

The program was not utilized during the year ended December 31, 2017. As of December 31, 2017, the Company had $97 million of availability remaining under its existing share repurchase authorization.
