CUSIP NO. 000918 102
This Amendment No. 6 (this "Amendment") amends and supplements the
Schedule 13D filed with the Securities and Exchange Commission on December 10,
1999 (the "Schedule 13D") by Aon Corporation, a Delaware corporation ("Aon"),
Aon Advisors, Inc., a Virginia corporation ("Aon Advisors"), Combined Insurance
Company of America, an Illinois corporation ("CICA"), and Virginia Surety
Company, an Illinois corporation ("VSC"), as previously amended. Aon, Aon
Advisors and CICA are sometimes referred to herein as the "Filing Persons". The
Schedule 13D as previously amended and this Amendment relate to the Common Stock
(the "Common Stock") of ACM Government Opportunity Fund, Inc. (the "Issuer").
Capitalized terms used but not defined herein have the meanings ascribed to such
terms in the Schedule 13D.
Item 5 of the Schedule 13D as previously amended is hereby amended and
restated in its entirety as follows:
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
See rows 7 through 11 and row 13 on pages 2 through 4.
The Issuer's Quarterly Report dated April 1, 2004 states that, as of
January 31, 2004, there were 12,864,505 shares of Common Stock outstanding. The
percentage ownership of Aon, Aon Advisors and CICA was derived using this number
of shares of Common Stock outstanding.
Pursuant to an Investment Advisory Agreement between Aon Advisors and
CICA, Aon Advisors is invested in, on behalf of and as investment adviser to
CICA, 3,918,136 shares of Common Stock. Because Aon is the parent holding
company to CICA, Aon indirectly beneficially owns all shares of Common Stock
held by CICA.
By reason of the purchases of Common Stock made on behalf of CICA, as
of the date of this Amendment, Aon, Aon Advisors and CICA share the power to
vote or direct the vote and the power to dispose or direct the disposition of
3,918,136 shares of Common Stock, or 30.5% of the total outstanding shares of
Common Stock as of January 31, 2004.
During the sixty day period preceding the date of this Amendment, none
of the Filing Persons effected any transactions in any shares of Common Stock
other than the following sales by Aon Advisors on behalf of CICA:
