Nuveen Unit Trusts, Series 18
Nuveen Communications Sector Portfolio, October 1998 (the "Trust")
- --------------------------------------------------------------------------------
On November 24, 1998, Sprint Corporation ("Sprint") recapitalized its
shares of common stock into two separate classes. Primarily, the split separates
Sprint's wireless services from the rest of its operations. Each holder of one
share of the old Sprint stock received one share of Sprint FON stock and
one-half share of Sprint PCS stock. Accordingly, the Trust's Schedule of
Investments on page 27 of the Prospectus is hereby revised to reflect the
exchange and that, as of November 24, 1998, the shares of Sprint FON and Sprint
PCS held by the Trust represented 2.90% and 0.34%, respectively, of the
aggregate offering price of the Trust. Please be advised that such percentages
are subject to change.
