PROSPECTUS DATED MAY 3, 1999
AS SUPPLEMENTED AUGUST 9, 1999
Effective March 31, 2000, all American
General Life Insurance Company Separate
Account D, Platinum Investor Contracts will
be changed to reflect a revision in the
method used to calculate death proceeds. The
revised method affects Contracts under which
the Annuitant or the Owner dies before the
Annuity Commencement Date. The revision in
the method used to calculate death proceeds
is subject to applicable state insurance
department approvals.
Please delete all of the
information beginning on page 32
and continuing through the first
paragraph of page 33 and insert in
its place the following:
DEATH PROCEEDS
Death Proceeds Before the Annuity
Commencement Date
The death proceeds described below are
payable to the Beneficiary under the
Contract if any of the following events
occurs before the Annuity Commencement Date:
o the Annuitant dies, and no Contingent
Annuitant has been named under a Non-
Qualified Contract;
o the Annuitant dies, and we also receive
proof of death of any named Contingent
Annuitant; or
o the Owner (including the first to die
in the case of joint Owners) of a Non-
Qualified Contract dies, regardless of
whether the deceased Owner was also the
Annuitant. (However, if the
Beneficiary is the Owner's surviving
spouse, or the Owner's surviving spouse
is a joint Owner, the surviving spouse
may elect to continue the Contract as
described later in this Section).
There is a standard manner for us to pay the
death proceeds when a joint Owner dies: we
treat the surviving joint Owner as the
Beneficiary and we pay the death proceeds to
the surviving joint Owner. Joint Owners may
give us written instructions to pay death
proceeds in a different manner.
The death proceeds, before deduction of any
premium taxes and other applicable tax, will
equal the greatest of --
o the sum of all net purchase payments
made reduced upon a partial withdrawal
in the same proportion as the reduction
in Account Value (for example, let's
say that your Account Value immediately
after you make a partial withdrawal is
5% less than what your Account Value
was immediately before you made the
partial withdrawal, then the death
proceeds immediately after you make the
partial withdrawal will be 5% less than
what the death proceeds would have been
immediately before you made the partial
withdrawal);
o the Owner's Account Value as of the end
of the Valuation Period in which we
receive, at our Home Office, proof of
death and a Written request as to the
manner of payment; or
o the "highest anniversary value" before
the date of death, as defined below.
The highest anniversary value before
the date of death will be determined
as follows:
(a) First, we will calculate the Account
Values at the end of each of the past
Contract Anniversaries that occur before the
deceased's 81st birthday (we will thereafter
use only the highest of the Contract
Anniversary Account Values that occurred
before the deceased's 81st birthday);
(b) Second, we will increase each of the
Account Values by the amount of net purchase
payments the Owner has made since the end of
such Contract Anniversaries; and
(c) Third, we will reduce the result upon a
partial withdrawal in the same proportion as
the reduction in Account Value (for example,
let's say that your Account Value
immediately after you make a partial
withdrawal is 5% less than what your Account
Value was immediately before you made the
partial withdrawal, then the highest of the
Contract Anniversary Account Values
immediately after you make the partial
withdrawal will be 5% less than what the
highest of the Contract Anniversary Account
Values would have been immediately before
you made the partial withdrawal).
The highest anniversary value will
be an amount equal to the highest
of such values. Net purchase
payments are purchase payments
less applicable taxes deducted at
the time the purchase payment is
made.
