This supplement updates certain information in the above-referenced prospectus
(the "Prospectus"). The terms used in this supplement have the same meaning as
in the Prospectus. This Supplement must be used in conjunction with the
Prospectus. If you need a copy of the current Prospectus, please call our
Annuity Service Center at (800) 445-7862 or visit our website at
www.corebridgefinancial.com/rila-documents.

The following replaces the definition included on page 7 in the SPECIAL TERMS
section:

Renewal Notice - The notification we send to Owners at least 10 days before the
Term End Date (or Contract Anniversary after a Performance Capture or a Lock
Threshold is met). Among other information, your Renewal Notice will, as
applicable, provide you with instructions to obtain (i) the Allocation Accounts
that will be available for investment and (ii) the rates applicable to each
Allocation Account that will be available for investment. The notification
will remind you to submit instructions to us before Market Close on the
Term End Date (or the next Contract Anniversary after a Performance Capture
or a Lock Threshold is met). If The Term End Date (or the next Contract
Anniversary after a Performance Capture or a Lock Threshold is met) is not a
Business Day, we must receive your instructions before Market Close on the
Business Day before the Term End Date (or the next Contract Anniversary after
a Performance Capture or a Lock Threshold is met). "Market Close" is the close
of the New York Stock Exchange on Business Days, usually at 4:00 p.m.
Eastern Time.

The following replaces the sixth bullet under Performance Capture Risk on
page 24 in the PRINCIPAL RISKS OF INVESTING IN THE CONTRACT section:

*	The Performance Capture Fixed Rate may change at each Contract Anniversary,
subject to a guaranteed minimum interest rate of 0.25%. If you are invested in
a Strategy Account Option with a multi-year Term, your Performance Captured
Fixed Rate may change from one Contract Anniversary to the next within
the Term.

The following replaces the second paragraph on page 29 in the ALLOCATION
ACCOUNTS section:

The Strategy Account Option rates are guaranteed for their applicable Term.
For all Allocation Account Options, we will send you a notice at least
ten (10) days prior to the Term End Date (or Contract Anniversary after a
Performance Capture or a Lock Threshold is met) explaining how you may obtain
the Allocation Accounts available to you for transfer on the Term End Date
(or Contract Anniversary after a Performance Capture or a Lock Threshold
is met) and the renewal interest rates and Strategy Account Option rates
declared for the next Term. You may obtain renewal interest rates and Strategy
Account Option rates online at www.corebridgefinancial.com/rila-rates
or by contacting your financial representative.

The following replaces the third from the last paragraph on page 29 under
Fixed Account Option in the ALLOCATION ACCOUNTS section:

We will send you a notice at least ten (10) days prior to the Term End Date
(or Contract Anniversary after a Performance Capture or a Lock Threshold
is met) explaining how you may obtain the Strategy Account Options available
to you for transfer on the Term End Date (or Contract Anniversary after a
Performance Capture or a Lock Threshold is met) and the renewal interest rates
and current Strategy Account Option rates declared for the next Term.

The following replaces the paragraph starting with "Term End Date" on page 41
in the SELECTING ALLOCATION ACCOUNTS FOR INVESTMENT section:

Term End Date. If you are coming to a Term End Date, we will send you a
Renewal Notice (which will include instructions to obtain then-current rates)
at least ten (10) days before the Term End Date. We must receive your
instructions before Market Close on the Term End Date. If the Term End Date
is not a Business Day, we must receive your instructions before Market Close
on the Business Day before the Term End Date.

The following replaces the last paragraph starting on page 41 in the
SELECTING ALLOCATION ACCOUNTS FOR INVESTMENT section:

We will send you a Renewal Notice (which will include instructions to obtain
then-current rates) at least ten (10) days before the next Contract
Anniversary, if you exercised a Performance Capture for a Strategy Account
Option or a Lock Threshold is met at Market Close for a Strategy Account Option
with Lock Upside Parameter. If you exercised a Performance Capture for a
Strategy Account Option or a Lock Threshold is met at Market Close for a
Strategy Account Option with Lock Upside Parameter within ten (10) days of the
next Contract Anniversary, you may not receive a Renewal Notice and should
obtain then current rates online at www.corebridgefinancial.com/rila-rates
or by contacting your financial representative.

The following replaces the bullet on page 47 in the VALUING YOUR INVESTMENT
IN A STRATEGY ACCOUNT OPTION section:

*	We may change the Performance Capture Fixed Rate at each Contract
Anniversary, subject to a guaranteed minimum interest rate of 0.25%. If you are
invested in a Strategy Account Option with a multi-year Term, your Performance
Captured Fixed Rate may change from one Contract Anniversary to the next
within the Term. Once a Strategy Account Option is Performance Captured,
the Performance Capture Fixed Rate used to credit daily interest will not
change before the next Contract Anniversary when the value is eligible for
transfer. For any date on which a fee, charge, or Withdrawal is deducted from
the applicable Strategy Account Option, daily interest will have been credited
before the deduction of the fee, charge, or Withdrawal.

         Please keep this supplement with your Prospectus for future reference.
