The Senate approved measures last week aimed at making it more difficult for executives to protect their compensation from creditors in the event of a bankruptcy. These measures came in response to Enron, Worldcom, and other scandals in which executives made away with millions while shareholders lost their entire investment. The new regulations put a $1 million limit on what many highly paid executives can place into a tax-free deferred compensation plan. The new provision, which was passed unanimously with a larger bundle of legislation, will also greatly increase taxes for a number of highly paid executives by millions of dollars over the next 10 years. The measure is part of a dozen other provisions aimed at limiting corporate and executive tax loopholes, after widespread abuses in the corporate world.
