RESPECT
TO
EFFECTIVELY
CONNECTED

amounts shall be includible in gross income in the

added by this section).

ance issued under paragraph (3) shall permit such 
arrangements to be amended to conform the dates of
distribution under such arrangement to the date 
amounts are required to be included in the income 
of such taxpayer under this subsection. 
(5) ACCELERATED PAYMENT NOT TREATED AS 
MATERIAL
MODIFICATION.—Any amendment to a 
nonqualified deferred compensation arrangement 
made pursuant to paragraph (3) or (4) shall not be
