Registered Products to Which This Filing Relates:
This notice is being filed with the U.S. Securities and Exchange Commission (the “SEC”) only with respect to the variable annuity contracts and variable life insurance policies listed in the table above, which are issued by AuguStar Life Insurance Company and National Security Life and Annuity Company through separate accounts registered with the SEC.
The same notice is also being sent to owners of certain variable life insurance policies that are not registered with the SEC and that have contract value allocated to one or more of the portfolios described below. The inclusion of this notice in an SEC filing does not mean that any such unregistered contract or policy, or the separate account through which it is issued, is registered with the SEC. This notice is not an offer to sell, or a solicitation of an offer to buy, any contract or policy.
November 3, 2026
Dear Contract Owner:
We’re contacting you to notify you that the Board of Directors (the “Board”) of the AuguStar Variable Insurance Products Fund, Inc. (the “Fund”) has approved three reorganizations (each, a “reorganization”), and each such reorganization involves portfolios available within your AuguStar variable annuity contract and/or variable life insurance policy (your “Contract”). After considering a number of factors, the Board concluded that each reorganization is in the best interests of each portfolio involved in that reorganization. For each reorganization, total annual operating expenses of the survivor portfolio are expected to be the same or lower than those of the target portfolio.
You are receiving this notice because you have Contract value allocated to one or more of the target portfolios listed in the table below. Depending on how your Contract value is allocated, you may be affected by one or more of the reorganizations. The information in this notice applies to you only with respect to each target portfolio to which you have Contract value allocated. As of the close of business on or about December 18, 2026, each target portfolio’s assets will be transferred to its corresponding survivor portfolio, and any Contract value you have allocated to a target portfolio immediately before its reorganization will be allocated to the corresponding survivor portfolio. Please note that the Fund may postpone or abandon the reorganization under certain circumstances.
| Target Portfolio | Survivor Portfolio |
| AVIP Fidelity Institutional AM® Equity Growth Portfolio | AVIP BlackRock Advantage Large Cap Growth Portfolio¹ |
| AVIP AB Relative Value Portfolio | AVIP S&P 500® Index Portfolio² |
| AVIP BlackRock Advantage Small Cap Growth Portfolio | AVIP AB Small Cap Portfolio³ |
| 1 | The survivor portfolio pursues a similar investment objective and substantially similar principal investment strategies as the target portfolio. |
| 2 | The survivor portfolio is an index portfolio that seeks to track the S&P 500® Index and, unlike the target portfolio, is not actively managed. |
| 3 | The survivor portfolio pursues a similar investment objective and substantially similar principal investment strategies as the target portfolio. |
Please note that you may not have money invested in all the portfolios listed above. These changes will take place automatically, and any future allocations under your Contract that are affected will also be updated automatically. You do not need to take any action unless you would prefer to reallocate your Contract value to other portfolios. From October 19, 2026, through February 16, 2027, you may make one transfer of Contract value out of a target portfolio or, after its reorganization, the corresponding survivor portfolio, without charge and without the transfer counting toward any transfer limit under your Contract. Transfer requests received in good order before the close of regular trading on the New York Stock Exchange on December 18, 2026 will be processed before the reorganizations. No sales charges, redemption fees or other transaction fees will result from the reorganizations.
Please note: If your plan maintains individual participant accounts, please provide a copy of this notice to the affected participants
