A group of 92 large law firms has written to the Internal Revenue Service requesting a one-year extension on compliance with �409A of the Internal Revenue Code.

Created by the 2004 Jobs Creation Act, �409A was intended to eliminate abuses associated with executive deferred compensation plans. The final rules were issued in April and provided for a Dec. 31, 2007, deadline for compliance, with participants in noncompliant plans to be assessed a 20 percent penalty.
