Replace the "Cybersecurity and Certain Business Continuity Risks" and "COVID-19 and Market Conditions" paragraphs in the "OTHER INFORMATION" section with the following new paragraphs:

Cybersecurity and Certain Business Continuity Risks. Our variable annuity contract business is largely conducted through complex information technology and communications systems operated by us and our service providers and business partners (e.g., the Investment Portfolios and the firms involved in the distribution and sale of our variable annuity contracts). Our operations rely on the secure processing, storage and transmission of confidential and other information in our systems and the systems of third party service providers. For example, many routine operations, such as processing Owners' requests and elections and day-to-day recordkeeping, are all executed through computer networks and systems. We have established administrative and technical controls and business continuity and resilience plans to protect our operations against attempts by unauthorized third parties to improperly access, modify, disrupt the operation of, or prevent access to critical networks or systems or data within them (a "cyber-attack"). Despite these protocols, the techniques used to attack systems ad networks change frequently, are becoming more sophisticated, and can originate from a wide variety of sources including terrorists, nation states, financially motivated actors, internal actors, or third parties, such as external service providers, and the techniques used change frequently or are often not recognized until after they have been launched. The rapid evolution and increased adoption of artificial intelligence technologies may intensify our cybersecurity risks, including the deployment of artificial intelligence technologies by threat actors. There may be an increased risk of cyber-attacks during periods of geo-political or military conflict.

A cyber-attack could have a material, negative impact on the Company and the Separate Account, as well as individual Owners and their contracts. There are inherent limitations in our plans and systems, including the possibility that certain risks have not been identified or that unknown threats may emerge in the future. Unanticipated problems with, or failures of, our disaster recovery systems and business continuity plans could have a material impact on our ability to conduct business and on our financial condition and operations, and such events could result in regulatory fines or sanctions, litigation, penalties or financial losses, reputational harm, loss of customers, and/or additional compliance costs for us. Our operations also could be negatively impacted by a cyber-attack affecting a third party, such as a service provider, business partner, another participant in the financial markets, or a governmental or regulatory authority. Potential attacks can occur through a variety of sources, including, but not limited to, cyber-attacks, phishing attacks, account takeover attempts, the introduction of computer viruses or malicious code, ransomware or other extortion tactics, denial of service attacks, credential stuffing, and other computer-related penetrations. Hardware, software or applications developed by us or received from third parties may contain exploitable vulnerabilities, bugs, or defects in design, maintenance or manufacture or other issues that could compromise information and cybersecurity. Malicious actors may attempt to fraudulently induce employees, customers, or other users of our systems to disclose credentials or other similar sensitive information in order to gain access to our systems or data, or that of our customers, through social engineering, phishing, mobile phone malware, and other methods. Cybersecurity threats can originate from a wide variety of sources including, but not limited to, natural catastrophe, military or terrorist actions, public health crises (such as the COVID-19 pandemic), and unanticipated problems with our or our service providers' disaster recovery systems. Such disasters and events may adversely affect our ability to conduct business or administer the contract, particularly if our employees or the employees of our service providers are unable or unwilling to perform their responsibilities as a result of any such event.

Cyber-attacks, disruptions or failures to our business operations can interfere with our processing of contract transactions, including the processing of transfer orders from our website or with the Investment Portfolios; impact our ability to calculate Accumulation Unit values; cause the release and/or possible loss, misappropriation or corruption of confidential Owner or business information; or impede order processing or cause other operational issues. Cyber-attacks, disruptions or failures may also impact the issuers of securities in which the Investment Portfolios invest, and it is possible the funds underlying your contract could lose value. There can be no assurance that we or our service providers or the Investment Portfolios will avoid losses affecting your contract due to cyber-attacks, disruptions or failures in the future. Although we continually make efforts to identify and reduce our exposure to cybersecurity risk, there is no guarantee that we will be able to successfully manage and mitigate this risk at all times. Furthermore, we cannot control the cybersecurity plans and systems implemented by third parties, including service providers or issuers of securities in which the Investment Portfolios invest.

The information shown in the table above was provided by the Investment Portfolios. Certain Investment Portfolios and their investment adviser have entered into expense reimbursement and/or fee waiver arrangements that will continue at least until April 28, 2025. These arrangements can be terminated with respect to these Investment Portfolios only with the approval of the Investment Portfolio's board of directors or trustees. Please see the Investment Portfolios' prospectuses for additional information regarding these arrangements.

Certain Investment Portfolios that have "Acquired Fund Fees and Expenses" are "funds of funds." A fund of funds invests substantially all of its assets in other underlying funds. Because the Investment Portfolio invests in other funds, it will bear its pro rata portion of the operating expenses of those underlying funds, including the management fee.
