SECTION 8 - OTHER EVENTS.

Item 8.01 Other Events.

Registrant  is  furnishing  as Exhibit  99.1 the  attached  amended and restated
"Frequently Asked Questions About Regulatory Matters" dated October 2, 2006.

This information supersedes and replaces the information contained in that
certain Current Report on Form 8-k filed by the Registrant on September 27,
2006.

In late 2003,  Seligman  conducted an extensive  internal  review in response to
public  announcements  concerning mutual fund trading  practices.  The following
discussion has been prepared to provide shareholders with important information.

For purposes of this  discussion,  J. & W. Seligman & Co.  Incorporated  and its
affiliates  and related  parties are referred to as "Seligman" or the "Manager,"
and  the  Seligman  registered  investment  companies  are  referred  to as  the
"Seligman Funds."

Q1. Have any Seligman employees engaged in improper trading?

A. The Manager conducted an internal review of employee trading in shares of the
Seligman Funds in the fall of 2003 and continues to monitor  employee trading in
the Seligman Funds.  The Manager has not found any improper  trading activity by
Seligman employees.

Q2. Does  Seligman  have any  policies  relating to employee  investment  in the
Seligman Funds?

A. A  majority  of  Seligman  employees  invest in the  Seligman  Funds,  either
directly or through the Seligman 401(k) plans. Trading by employees is monitored
by the  Manager's  legal  department  and is  subject to the  Manager's  Code of
Ethics.  In addition,  unlike many 401(k) plans that permit daily  trading,  the
Seligman  401(k)  plans  permit  only  weekly  trading  activity.  All  Seligman
employees have been informed that excessive trading with respect to the Seligman
Funds,  or trading in the  Seligman  Funds  based upon  inside  information,  is
inappropriate  and may, in certain  cases,  be illegal.  Employees who engage in
inappropriate  trading will be subject to disciplinary action, which may include
termination of employment.

Q3. Has Seligman engaged in improper disclosure of a Fund's portfolio holdings?

A. The Manager has found no improprieties relating to the disclosure of a Fund's
portfolio holdings. The Manager has not disclosed and does not disclose a Fund's
portfolio holdings prior to public dissemination, unless such disclosure is made
for  legitimate  business  purposes and only if the Manager  believes  that such
disclosure  will not be detrimental to a Fund's  interest.  A description of the
policies and procedures with respect to the disclosure of each Fund's  portfolio
securities is set forth in each Fund's Statement of Additional Information.

Q4. What is Seligman's policy with regard to receipt of late trades (i.e., after
4:00 pm Eastern Time)?

A.  Seligman  does not accept late trades  directly  from Fund  shareholders  or
prospective shareholders.  The large majority of mutual fund trades submitted to
Seligman are from  broker-dealer  firms and other  financial  intermediaries  on
behalf of their clients.  These intermediaries have an obligation to ensure that
trades  submitted to the Seligman  Funds after 4:00 pm on a trading day for that
day's net asset value were,  in fact,  received by those  entities by 4:00 pm on
that day. This applies to all trades from  intermediaries,  including those that
are transmitted electronically to Seligman after the market closes. Although the
Seligman Funds and the Manager,  like other mutual fund groups, cannot determine
the time at which orders received through financial  intermediaries were placed,
the  Manager  expects  mutual  fund trades  submitted  to Seligman by  financial
intermediaries to comply with all applicable laws and regulations.  Seligman has
contacted every financial  intermediary that offers,  sells, or purchases shares
of the Seligman Funds in order to remind all of them of their  responsibility to
have  reasonable  policies and  procedures to ensure that they comply with their
legal and  contractual  obligations.  The Manager has found no instances of Fund
shareholders engaging in late trading directly with the Seligman Funds. Seligman
will cooperate with and support



any  governmental or regulatory  investigation  to identify and hold accountable
any financial  intermediary that has submitted orders in violation of applicable
laws or regulations.

Q5. What is Seligman's policy regarding market timing?

A. Seligman has policies and procedures in place to restrict trades that, in its
judgment, could prove disruptive in the management of portfolios of the Seligman
Funds.  As part of the  Manager's  procedures,  the Manager  frequently  rejects
trades,  issues  warning  letters,  and prohibits  accounts from making  further
exchanges.  Since September 2003, when the first proceedings relating to trading
practices within the mutual fund industry were publicly announced,  Seligman has
taken  additional  steps to strengthen  its policies and  procedures.  A general
description  of the  Seligman  Funds'  policies  is set  forth  in  each  Fund's
prospectus.

Q6. Has Seligman conducted an internal review relating to market timing?

A. The  Manager  completed  its  internal  review  in the  fall of  2003.  As of
September 2003, the Manager had one arrangement that permitted frequent trading.
This  arrangement  was in the process of being closed down by the Manager before
September  2003.  Based on a review of the  Manager's  records for 2001  through
2003,  the  Manager  identified  three  other  arrangements  that had  permitted
frequent  trading in the Seligman  Funds.  All three had already been terminated
prior to the end of September 2002. The results of the Manager's internal review
were presented to the  Independent  Directors of the Seligman Funds. In order to
resolve   matters  with  the   Independent   Directors   relating  to  the  four
arrangements,  the  Manager in May 2004 paid  approximately  $75,000 to Seligman
Global Growth Fund,  $300,000 to Seligman Global Smaller Companies Fund and $1.6
million to Seligman  Global  Technology  Fund in  recognition  that these global
investment  funds presented some potential for time zone arbitrage.  The amounts
paid by the  Manager  represented  less than 1/2 of 1% of each such  Fund's  net
asset value as of the date such payments were made. In addition, with respect to
Seligman  Communications and Information Fund and notwithstanding that time zone
arbitrage  opportunities  did not  exist,  the  Manager,  at the  request of the
Independent  Directors,  agreed  to  waive  a  portion  of its  management  fee,
amounting to five basis points (0.05%) per annum,  for that Fund for a period of
two years commencing on June 1, 2004.

Q7. Does Seligman disclose its internal market timing control procedures?

A.  Seligman's  market timing control  procedures are  proprietary.  The Manager
believes that disclosing these procedures will reduce their effectiveness.

Q8. What new practices are being considered to prevent market timing abuses?

A. Like other members of the mutual fund industry,  Seligman has considered, and
continues  to  consider,  numerous  options,  including  the  implementation  of
redemption fees.  Seligman also has contacted every financial  intermediary that
offers,  sells, or purchases shares of the Seligman Funds in order to inform all
of them that they must have  reasonable  policies and  procedures to ensure that
they do not  knowingly  permit or facilitate  excessive  trading of the Seligman
Funds or  knowingly  use or  facilitate  any methods  designed to disguise  such
trading in the Seligman Funds.

Q9. Is Seligman  involved  with any federal or state  investigation  relating to
market timing or late trading?

A.  Beginning in February 2004,  Seligman was in  discussions  with the New York
staff of the SEC and the  Office  of the New York  Attorney  General  ("Attorney
General") in connection with their review of frequent  trading in certain of the
Seligman mutual funds.  No late trading is involved.  This review was apparently
stimulated  by  Seligman's   voluntary   public   disclosure  of  the  foregoing
arrangements  in January 2004. In March 2005,  negotiations to settle the matter
were  initiated  by the New York  staff  of the SEC.  After  several  months  of
negotiations,  tentative agreement was reached,  both with the New York staff of
the SEC and the  Attorney  General,  on the  financial  terms  of a  settlement.
However,  settlement  discussions  with  the  Attorney  General  ended  when the
Attorney  General  sought to impose  operating  conditions on Seligman that were
unacceptable  to  Seligman,  would  have  applied  in  perpetuity  and  were not
requested  or required by the SEC.  Subsequently,  the New York staff of the SEC
indicated  that,  in lieu of moving  forward  under  the terms of the  tentative
financial   settlement,   the  staff  was   considering   recommending   to  the
Commissioners  of the SEC the  instituting of a formal action against  Seligman.
Seligman  believes that any action would be both  inappropriate and unnecessary,
especially in light of the fact that Seligman previously resolved the underlying
issue with the  Independent  Directors of the Seligman Funds and made recompense
to the affected Funds.

Immediately  after  settlement  discussions with the Attorney General ended, the
Attorney  General  issued  subpoenas to certain of the Seligman  Funds and their
directors. The subpoenas sought various Board materials and information relating
to the  deliberations of the Independent  Directors as to the advisory fees paid
by the  Seligman  mutual funds to  Seligman.  Seligman  objected to the Attorney
General's  seeking of such  information and, on September 6, 2005, filed suit in
federal  district  court seeking to enjoin the Attorney  General from pursuing a
fee inquiry.  Seligman believes that the Attorney  General's inquiry is improper
because Congress has vested exclusive regulatory oversight of investment company
advisory fees in the SEC.

At the end of September 2005, the Attorney General indicated that it intended to
file an action at some point in the future alleging, in substance, that Seligman
permitted   other  persons  to  engage  in  frequent   trading  other  than  the
arrangements described above and, as a result, the prospectus disclosure used by
the  Seligman  Funds is and has been  misleading.  On September  26,  2006,  the
Attorney  General  commenced  a civil  action in New York  State  Supreme  Court
against J. & W. Seligman & Co. Incorporated,  Seligman Advisors,  Inc., Seligman
Data Corp. and Brian T. Zino,  reiterating,  in substance,  the foregoing claims
and various other  related  matters.  The Attorney  General also claims that the
fees charged by Seligman are excessive.  The Attorney General is seeking damages
and restitution,  disgorgement,  penalties and costs (collectively,  "Damages"),
including  Damages of at least $80 million  relating to alleged timing occurring
in the Seligman  Funds and  disgorgement  of profits and  management  fees,  and
injunctive  relief.  Seligman  and Mr. Zino  believe that the claims are without
merit and intend to defend themselves vigorously.

Any resolution of these matters with regulatory authorities may include, but not
be limited to, the relief sought by the Attorney  General or other  sanctions or
changes in  procedures.  Any  Damages  will be paid by  Seligman  and not by the
Seligman Funds. If Seligman is unsuccessful in its defense of these proceedings,
it and its affiliates  could be barred from  providing  services to the Seligman
Funds,  including  serving as an investment  adviser for the Seligman  Funds and
principal  underwriter for the open-end  Seligman Funds. If these results occur,
Seligman will seek exemptive relief from the SEC to permit it and its affiliates
to continue to provide  services to the  Seligman  Funds.  There is no assurance
that such exemptive relief will be granted.

Seligman  does not believe that the  foregoing  legal  action or other  possible
actions should have a material adverse impact on Seligman or the Seligman Funds;
however, there can be no assurance of this or that these matters and any related
publicity  will not result in reduced demand for shares of the Seligman Funds or
other adverse consequences.

Q10. Does Seligman have any market timing arrangements at the current time?

A. Market timing  arrangements  in the Seligman Funds have been  prohibited.  In
addition,  Seligman has  strengthened  existing  controls to discourage and help
prevent market timing.

Q11.  Have any  employees  been  disciplined  in  connection  with the Manager's
overall internal review?

A. One employee has left Seligman.
