CME Group threatens to leave Illinois over taxes

Tax increases have consequences. The Chicago Tribune reports:

CME's Executive Chairman, Terry Duffy, said the company was exploring a potential move of its corporate base, after Illinois earlier this year sharply lifted the corporate tax rate paid by the Chicago-based exchange company.

He and other top executives of CME Group Inc. on Wednesday also acknowledged investor frustration with the exchange company's share price and promised to consider moves such as a special dividend or a stock split to improve it.

No word yet from former CME board member Rahm Emanuel on this one. Going Galt in Barack Obama's hometown.
