This supplement is intended to update certain information in the prospectus you received for the Index Achiever Advisory Annuity and the Index Achiever Annuity and in any supplements to that prospectus (collectively, the “Prospectus”). All other provisions outlined in the Prospectus remain unchanged. Unless otherwise indicated, terms used in this supplement have the same meaning as in the Prospectus.

The “STATE VARIATIONS” section of each Prospectus is replaced in its entirety with the following:

STATE VARIATIONS

This prospectus describes the material features of the Contract. Contracts issued in your state may provide different features and benefits from, and impose different costs than, those described in this prospectus because of state law variations. However, please note that the maximum charge is set forth in this prospectus. If you would like to review a copy of the Contract and any endorsements, contact us at P.O. Box 5423, Cincinnati, OH 45201-5423, visit our website at www.GAIGannuities.com or call us at 1-800-789-6771.

The following information is a summary of material state variations as of the date of this prospectus.

Temporary Holding Account

For Contracts Issued in Missouri

For Contracts issued in Missouri, there is no Declared Rate Strategy. Amounts can be allocated or reallocated to a Temporary Holding Account. The value of the Temporary Holding Account is equal to: (1) the amounts applied to the Temporary Holding Account at the start of the current Term; minus (2) each withdrawal taken from the Temporary Holding Account during the current Term; minus (3) each rider charge taken from the Temporary Holding Account during the current Term; and plus (4) interest that we have credited on the balances in the Temporary Holding Account for the current Term.

The Temporary Holding Account earns interest daily at an annual effective rate equal to the interest rate used to calculate the minimum value under Missouri standard nonforfeiture law for a fixed annuity contract on the Contract issue date.

Allocations and reallocations to the Temporary Holding Account are subject to the Allocation Limit.

At the end of a Term, to the extent any amount cannot be applied to a Temporary Holding Account for the next Term because the amount is over the Allocation Limit, unless you send us a request to reallocate that amount we will apply the amount to the S&P 500 –10% Floor Strategy.

Amounts taken from the Temporary Holding Account on a withdrawal or a Surrender are not subject to a Market Value Adjustment.

Market Value Adjustment

For Contracts Issued in Connecticut, Indiana, and Maryland

The MVA formula does not include a spread factor. The MVA factor is equal to:

(A – B) x N

Where:

= the MVA Index Interest Rate on the Contract Effective Date;

= the MVA Index Interest Rate for the date of the withdrawal or Surrender; and

= the number of whole and partial years remaining to the sixth Contract Anniversary.

General

For Contracts Issued in Illinois

References to “spouse” have been changed to “spouse or civil union partner.”

For Contracts Issued in New Jersey

References to “spouse” have been changed to “spouse or civil union partner.”

Extended Care Waiver Rider

For Contracts Issued in California

The Waiver of Market Value Adjustments for Facility Care or Home Care or Community-Based Services Rider (CA Rider) provides a waiver under an expanded set of circumstances. The waiver will apply if, at the time of a Surrender, or within the immediately preceding 90 days, the following conditions are met: (1) the insured is confined in a facility or is receiving, as prescribed by a physician, registered nurse or licensed social worker, home care or community-based services; (2) the insured’s confinement in a facility, the insured’s receipt of home care or community-based services, or any combination thereof has continued for a period of at least 90 consecutive days; and (3) the first day of such 90-day period was at least one year after the contract effective date. Facility includes a skilled nursing facility, a convalescent nursing home, or an extended care facility or a residential care facility or a residential care facility for the elderly. Home care or community-based services includes home health care, adult day care, personal care, homemaker services, hospice services and respite care as defined in the rider. Additional conforming changes have been made including revised and new definitions, and inclusion of a description of circumstances under which the waiver does not apply. The termination provision has been modified to reflect that the rider will not terminate if you transfer or assign an interest in the contract to a person or entity other than the insured.

For Contracts Issued in Connecticut

The conditions under which the waiver applies have been modified. The waiver will apply if at the time of a Surrender or within the immediately preceding 90 days all of the following conditions are met: (1) an insured is confined in a long-term care facility or hospital; and (2) the confinement has continued for a period of at least 90 consecutive days.

The definition of long-term care facility has been modified. The following facilities have been deleted from the list of facilities excluded from that definition: a facility that primarily treats drug addicts and a facility that is a home for the mentally ill. An exclusion provision has been added to clarify that the waiver will not apply if the insured is confined in a long-term care facility or hospital for the treatment of certain types of drug addiction or mental illnesses.

The definition of hospital has been modified by changing the phrase “it maintains, or has access to, medical, diagnostic, and major surgical facilities” to “it maintains, or has access to, medical and diagnostic facilities.”

For Contracts Issued in Vermont

The definition of long-term care facility has been modified. The following facilities have been deleted from the list of excluded facilities: a facility that primarily treats drug addicts, a facility that primarily treats alcoholics, and a facility that is a home for the mentally ill. In addition, the definition of physician has been modified by changing the phrase “a person who is licensed in the United States as a medical doctor or a doctor of osteopathy and who is practicing within the scope of his or her license” to “a person who is licensed in the United States who is providing medical care and treatment when such services are provided within the scope of his or her license and provided pursuant to applicable law.”

For Contracts Issued in Washington

The waiver is based on confinement to an extended care facility or hospital rather than a long-term care facility or hospital. Definitions are modified to reflect the new terminology, references to “skilled nursing facility” are changed to “nursing facility” and the related definition is modified.
