CHICAGO, Dec. 5, 2012

CHICAGO, Dec. 5, 2012 /PRNewswire/ -- CME Group Inc. (NASDAQ: CME) today
declared its annual variable dividend, amounting to $1.30 per share. The
dividend is payable December 28, 2012, to shareholders of record December 17,
2012. When CME Group adopted its annual variable dividend structure in
February 2012, the intention was to determine the amount after the end of each
year, with the level to increase or decrease from year to year based on
operating results, potential investment activity, and other forms of capital
return including regular dividends and share buybacks during the prior year.
Because of uncertainty regarding future taxation of dividends, CME Group's
board of directors has accelerated the timing of this dividend – which would
have been paid in first-quarter 2013 – into the fourth quarter of 2012 in
order to maximize the after-tax value to its shareholders.

CME Group paid its first annual variable dividend in March 2012, in the amount
of $0.60 per share on a post-split basis.

The accelerated annual variable dividend is supplemental to the regular
quarterly dividend of $0.45 per share payable December 26, 2012, to
shareholders of record December 10, 2012. In total during calendar year 2012,
considering four quarterly dividends and two variable annual dividends, the
company will have returned $3.69 per share to shareholders.

business without violating the intellectual property rights of others; our
ability to generate revenue from our market data that may be reduced or
eliminated by the growth of electronic trading, the state of the overall
economy or declines in subscriptions; changes in our rate per contract due to
shifts in the mix of the products traded, the trading venue and the mix of
customers (whether the customer receives member or non-member fees or
participates in one of our various incentive programs) and the impact of our
tiered pricing structure; the ability of our financial safeguards package to
adequately protect us from the credit risks of clearing members; the ability
of our compliance and risk management methods to effectively monitor and
manage our risks, including our ability to prevent errors and misconduct and
protect our infrastructure against security breaches and misappropriation of
our intellectual property assets; changes in price levels and volatility in
the derivatives markets and in underlying fixed income, equity, foreign
exchange, interest rate and commodities markets; economic, political and
market conditions, including the volatility of the capital and credit markets
and the impact of economic conditions on the trading activity of our current
and potential customers stemming from the financial crisis that began in 2008
and any other future crises; our ability to accommodate increases in trading
volume and order transaction traffic without failure or degradation of
performance of our trading and clearing systems; our ability to execute our
growth strategy and maintain our growth effectively; our ability to manage the
risks and control the costs associated with our acquisition, investment and
alliance strategy; our ability to continue to generate funds and/or manage our
indebtedness to allow us to continue to invest in our business; industry and

seasonality of the futures business. More detailed information about factors
