Supplement Dated December 23, 1997 to
Prospectus Dated May 1, 1997
as Supplemented November 6, 1997
On December 23, 1997, shareholders of the Short Term Global Government Fund of
The Sierra Variable Trust ("Trust") approved an Agreement and Plan of
Reorganization that would result in the Short Term Global Government Fund being
reorganized ("merged") into and with the Short Term High Quality Bond Fund of
the Trust. It is anticipated that this reorganization would take place on or
about January 16, 1998. As a result, the Short Term Global Government Fund
would cease to exist. In anticipation of this reorganization, the Trust will
discontinue the offering of shares of the Short Term Global Government Fund to
American General Life Insurance Company ("AGL"), effective January 12, 1998.
Accordingly, AGL will remove the Short Term Global Government Division of its
Separate Account D, effective January 12, 1998.
You may invest, through Separate Account D Divisions, in the other Funds of the
Trust -- but not the Short Term Global Government Fund of the Trust.
The Trust Prospectus is amended and supplemented as follows: Effective January
12, 1998, shares of Short Term Global Government Fund will no longer be offered
or sold to AGL, except for the reinvestment of dividends, payable between
January 12, 1998 and the effective date of the reorganization, attributable to
current shares of the Fund.
The Separate Account D Prospectus is amended and supplemented as follows:
Effective January 12, 1998, no portion of purchase payments under the Contracts
may be allocated, and no portion of your Account Value may be reallocated, to
the Short Term Global Government Division of Separate Account D.
Upon the reorganization, a Contract owner's Account Value allocated to the Short
Term Global Government Division would be converted into the same dollar amount
of Account Value in the Short Term High Quality Bond Division, based on values
on the date of the reorganization. AGL would send to each such Contract owner a
confirmation specifying, as of the reorganization, the number of units, and
their value, allocated to the Short Term High Quality Bond Division. The
Contract owner will not bear any expenses directly attributable to the
reorganization.
