McGuireWoods Consulting, led by Mike Cassidy and assisted by Darren
Collier, John Dunn and Tom Londrigan, succeeded in steering a $330 million tax relief package through
the Illinois General Assembly during last week’s special legislative session.
The package includes a tax restructure that will save their client, the CME
Group, $85 million per year. The bill was signed into law by the governor on
Dec. 16, 2011.
