Risks [Table Text Block]
RISKS
Is There a Risk of Loss from Poor Performance?
 
Yes.
The contract is subject to the risk of loss. You could lose some or all of your account value depending on the investment options you choose.
 
For additional information about the risk of loss see “Principal risks of investing in the contract” in this prospectus.
Is this a Short-Term Investment?
 
No.
The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash because the contract is designed to provide for the accumulation of retirement savings and income on a long-term basis. As such, you should not use the contract as a short-term investment or savings vehicle. A withdrawal charge may apply in certain circumstances and any withdrawals may also be subject to federal and state income taxes and tax penalties.
 
For additional information about the investment profile of the contract see “Fee table” in this prospectus.
What Are the Risks Associated with the Investment Options?
 
An investment in the contract is subject to the risk of poor investment performance and can vary depending on the performance of the investment options available under the contract (e.g., the Pooled Separate Accounts and the Portfolios). Each investment option, including the fixed investment options, has its own unique risks. You should review the investment options available under the contract before making an investment decision.
 
For additional information about the risks associated with investment options see “Portfolios of the trusts” in “MRP Investment options” and Appendix: “Investment Options Available Under the Contract” in this prospectus.
What Are the Risks Related to the Insurance Company?
 
An investment in the contract is subject to the risks related to the Company. Equitable Financial Life Insurance Company is solely responsible to the contract owner and participants for the contract’s account value. The general obligations under the contract, including the fixed investment options, are supported by our general account and are subject to our claims paying ability. An owner and participant should look solely to our financial strength for our claims-paying ability. More information about Equitable Financial Life Insurance Company, including our financial strength ratings, may be obtained upon request by calling
1-800-789-7771.
 
For additional information about insurance company risks see “About the general account” in “More information” in this prospectus.
 
Investment Restrictions [Text Block]
Yes.
You may transfer accumulated amounts among the investment options under your contract at any time and in any amount, subject to certain transfer limitations described in this prospectus. We reserve the right to remove or substitute Portfolios and Pooled Separate Accounts as investment options.
 
For additional information about restrictions on the investment options see “MRP Investment options” and “Transferring your money among investment options” in this prospectus.
 
Transfers from the guaranteed interest option may be subject to limitations. From time to time, we may remove certain restrictions that apply to transferring amounts out of the guaranteed interest option. If we do so, we will tell you. We will also tell you at least 45 days in advance of the day that we intend to reimpose those transfer restrictions.
 
Contributions and transfers into and out of the guaranteed interest option are limited.
 
For additional information about the guaranteed interest option see “Guaranteed interest option” in “MRP Investment Options” in this prospectus.
Key Information, Benefit Restrictions [Text Block]
Yes.
Participant Loans. Not all employer plans will offer loans. Loans are subject to restrictions under federal tax rules and ERISA. The minimum loan amount and maximum loan amount is determined by your employer plan. The maximum amount of a loan is also limited by federal tax rules. Any interest charged on participant loans is determined by the employer plan.
 
See “Participant Loans” in “Benefits Available Under the Contract” in this prospectus.
Tax Implications [Text Block]
You should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract. There is no additional tax benefit to you if the contract is purchased through a
tax-qualified
plan or individual retirement account (IRA). Withdrawals will be subject to ordinary income tax and may be subject to tax penalties. Generally, you are not taxed until you make a withdrawal from the contract.
 
For additional information about tax implications see “Tax information” in this prospectus.
Investment Professional Compensation [Text Block]
Some employees may receive incentive compensation for performing marketing and service functions under the contract.
 
For additional information about compensation see “Distribution of the contracts” in “More information” in this prospectus.
Exchanges [Text Block]
Some financial professionals may have a financial incentive to offer a new contract in place of the one you already own. You should only exchange your contract if you determine, after comparing the features, fees, and risks of both contracts, as well as any fees or penalties to terminate your existing contract, that it is preferable to purchase the new contract rather than continue to own your existing contract.
 
For additional information about the charges you might incur in connection with an exchange see “Charges and expenses” in this prospectus.

Examples
 
These examples are intended to help you compare the cost of investing in the variable investment options with the cost of investing in other annuity contracts that offer variable investment options. These costs include transaction expenses, annual contract expenses, and annual Portfolio and Pooled Separate Account fees and expenses. The first set of examples assumes you invest all of your account value in the most expensive underlying Portfolio. The second set of examples assumes you invest all of your account value in the most expensive Pooled Separate Account, the AllianceBernstein Balanced Pooled Separate Account.

3.
Principal Risks of Investing in the Contract
 
 
 
The risks identified below are the principal risks of investing in the contract. The contract may be subject to additional risks other than those identified and described in this prospectus.
 
Risks Associated with Variable Investment Options and Pooled Separate Accounts
 
You take all the investment risk for amounts allocated to one or more of the investment options. If the investment options you select increase in value, then your account value goes up; if they decrease in value, your account value goes down. How much your account value goes up or down depends on the performance of the investment options in which you invest. We do not guarantee the investment results of any investment option. An investment in the contract is subject to the risk of poor investment performance, and the value of your investment can vary depending on the performance of the selected investment option, each of which has its own unique risks. You should review the variable investment options and Pooled Separate Accounts before making an investment decision.
 
Insurance Company Risk
 
No company other than Equitable Financial Life Insurance Company has any legal responsibility to pay amounts that we owe under the contract, including amounts allocated to the guaranteed interest option. The general obligations and any guaranteed interest option under the contract are supported by our general account and are subject to our claims paying ability. You should look solely to our financial strength for our claims-paying ability.
 
Possible Fees on Access to Account Value
 
We may apply fees if you access your account value during the accumulation period or surrender your contract. For example, in addition to possible tax consequences you may incur fees for accessing your account value such as a program expense charge.
 
Limitations on Access to Account Value Through Withdrawals
 
Withdrawals are generally subject to federal and state income tax, and may be subject to tax penalties if taken before age 59
1
2
. Additionally, there could be a delay in withdrawals from the guaranteed interest option of up to 5 years.
 
Possible Adverse Tax Consequences
 
The tax considerations associated with the contract vary and can be complicated. The applicable tax rules can differ,
depending on the type of plan. We cannot provide detailed information on all tax aspects of the contract. Moreover, the tax
aspects
that apply to a particular person’s contract may vary depending on the facts applicable to that person. Tax rules may change without notice. We cannot predict whether, when, or how these rules could change. Any change could affect contracts purchased before the change. Congress may also consider further proposals to comprehensively reform or overhaul the United States tax and retirement systems, which if enacted, could affect the tax benefits of a contract. We cannot predict what, if any, legislation will actually be proposed or enacted. Before making contributions to your contract or taking other action related to your contract, you should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract.
 
Not a Short-Term Investment
 
The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash because the contract is designed to provide for the accumulation of retirement savings and income on a long-term basis. As such, you should not use the contract as a short-term investment or savings vehicle and you should consider whether investing in the contract is consistent with the purpose for which the investment is being considered.
 
Risk of Loss
 
All investments have risks to some degree and it is possible that you could lose money by investing in the contract. An investment in the contract is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
 
Risk Associated with Taking a Loan
 
Loans will decrease your account value and death benefit, and loaned amounts will not participate in the investment experience of your investment options. There may be adverse tax consequences associated with taking a loan from your contract.
 
Contract Changes Risk
 
We may, at any time, exercise our rights to limit or terminate your contributions, allocations and transfers to any of the variable investment options. We reserve the right, subject to compliance with laws that apply, to remove variable investment options from the Separate Account, to combine any two or more variable investment options, to restrict or eliminate any voting rights as to the Separate Account, to limit or
 
terminate contributions or transfers into any of the variable investment options, and to limit the number of variable investment options you may select.
 
You should evaluate whether our ability to make the changes described above, and your ability to react to such changes, are appropriate based on your investment goals. When such changes occur, you should also evaluate whether those changes are appropriate based on your investment goals and, if not, you should evaluate your options under the Contract, which may be limited and may have negative consequences associated with them, as described in this prospectus.
 
Business disruption, cybersecurity, and artificial intelligence (“AI”) technologies risks
 
We rely heavily on technology, including interconnected computer systems and data storage networks and digital communications, to conduct our business. Because our business is highly dependent upon the effective operation of our computer systems and those of our service providers and other business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyberattacks. Cyberattacks may be systemic (e.g., affecting the internet, cloud services, or other infrastructure) or targeted (e.g., failures in or breach of our systems or those of third parties on whom we rely, including ransomware and malware attacks). Cybersecurity risks include, among other things, the loss, theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on our websites (or the websites of third parties on whom we rely), other operational disruption and unauthorized release, use or abuse of confidential customer information. The risk of cyberattacks may be higher during periods of geopolitical turmoil. Due to the increasing sophistication of cyberattacks, a cybersecurity breach could occur and persist for an extended period of time without detection. Systems failures and cyberattacks, as well as, any other catastrophic event, including natural and manmade disasters, public health emergencies, pandemic diseases, terrorist attacks, floods or severe storms affecting us, any third-party administrator, the underlying funds, intermediaries and other affiliated or third-party service providers may adversely affect us, our business operations and your account value and interfere with our ability to process contract transactions and calculate account values. Systems failures and cyberattacks may also interfere with our processing of contract transactions, including the processing of orders from our website or with the underlying funds, impact our ability to calculate account values and unit values and/or the underlying funds to be unable to calculate share values, cause the release or possible destruction of confidential customer and/or business information, impede order processing or cause other operational issues, subject us and/or our service providers and intermediaries to regulatory fines, litigation and financial losses and/or cause reputational damage. Cybersecurity risks may also impact the issuers of
securities in which the underlying funds invest, which may cause the underlying funds to lose value. The preventative actions we take to reduce the frequency and severity of cybersecurity incidents and protect our computer systems may be insufficient to prevent a cybersecurity breach from impacting our operations or your contract value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid cybersecurity breaches affecting your contract.
 
The development and deployment of AI tools and technologies, including generative AI, and its use and anticipated use by us or by third parties on whom we rely, may increase our existing operational risks or create new operational risks that we are not currently anticipating. AI and generative AI may be misused by us or by third parties upon which we rely, and that risk is increased by the relative newness of the technology, the speed at which it is being adopted, and the uncertain and evolving policy and regulatory landscape governing its use. Such misuse could expose us to legal or regulatory risk. Because the generative AI technology is so new, many of the potential risks of generative AI are currently unknowable.
 
In addition, we are also exposed to risks related to natural and man-made disasters, including, but not limited to, the occurrence of any storms, fires, floods, earthquakes, public health crises, malicious acts, and terrorist acts or any other event, which could adversely affect our ability to conduct business. A natural or man-made disaster, including a pandemic such as COVID-19, could result in our workforce, and/or employees of service providers and/or third-party administrators, being compromised and unable or unwilling to fully perform their responsibilities, which could likewise result in interruptions in our service. This could interfere with our processing of contract transactions, including processing orders from owners and orders with the underlying funds, impact our ability to calculate contract value, or have other adverse impacts on our operations. These events may also negatively affect our service providers and intermediaries, the underlying funds and issuers of securities in which the underlying funds invest, which may cause the funds underlying your contract to lose value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid negative impacts associated with natural and man-made disasters.

Participant Recordkeeping Services
 
Services Provided.
Depending on the type of plan your employer elected, we may provide either plan-level and participant-level recordkeeping or recordkeeping services for plan assets in the Pooled Trust. Where we provide participant recordkeeping services, we:
 
  establish an individual participant account for each participant covered by your employer’s plan based on data your employer provides;
 
  receive and deposit contributions on behalf of participants to individual participant accounts;
 
  maintain records reflecting, for each participant, contributions, transfers, loan transactions, withdrawals and investment experience and interest accrued, as applicable, on an individual participant’s proportionate values in the plan;
 
  provide to your employer individual participant’s reports reflecting the activity in the individual participant’s proportionate interest in the plan; and
 
  process transfers and distributions of the participant’s portion of his or her share of the employer plan assets among the investment options as your employer instructs.
 
Fees.
We charge an annual fee of $15 per participant paid in quarterly installments of $3.75. We deduct the fee from the amounts attributable to each individual participant at the end of each quarter by means of a reduction of units or a cash withdrawal from the guaranteed interest option.
 
Enrollment.
Only your employer can choose to enroll in a plan that offers participant level recordkeeping services.
 
Participant Loans
 
Participant loans are available if the employer plan permits them. Participants must apply for a plan loan through the
employer. The number of plan loans outstanding are subject to the terms of the employer’s plan. Loans are subject to restrictions under federal tax laws and ERISA, and are also subject to the limits of the plan. Loan packages containing all necessary forms, along with an explanation of how interest rates are set, are available from our Retirement Plan Account Managers. If a participant is married, written spousal consent may be required for a loan.
 
Generally, the loan amount will be transferred from the investment options into a loan account. The loan amount will not earn interest under the contract while the loan is outstanding, and you may be charged interest as set by the employer plan. The participant must repay the amount borrowed with interest as required by federal income tax rules. If you fail to repay the loan when due, the amount of the unpaid balance may be taxable and subject to additional penalty taxes. No participant who has defaulted on a loan under the employer plan shall be granted any additional loans under this plan. Interest paid on a retirement plan loan is not deductible.
 
Amounts borrowed from your contract do not participate in separate account investment experience and therefore, loans can affect the account value whether or not you repay the loan. The account value when you surrender, die, or terminate your contract will be reduced by the amount of any outstanding loan plus accrued interest.

You take all the investment risk for amounts allocated to one or more of the investment options. If the investment options you select increase in value, then your account value goes up; if they decrease in value, your account value goes down. How much your account value goes up or down depends on the performance of the investment options in which you invest. We do not guarantee the investment results of any investment option. An investment in the contract is subject to the risk of poor investment performance, and the value of your investment can vary depending on the performance of the selected investment option, each of which has its own unique risks.

Possible Adverse Tax Consequences
 
The tax considerations associated with the contract vary and can be complicated. The applicable tax rules can differ,
depending on the type of plan. We cannot provide detailed information on all tax aspects of the contract. Moreover, the tax
aspects
that apply to a particular person’s contract may vary depending on the facts applicable to that person. Tax rules may change without notice. We cannot predict whether, when, or how these rules could change. Any change could affect contracts purchased before the change. Congress may also consider further proposals to comprehensively reform or overhaul the United States tax and retirement systems, which if enacted, could affect the tax benefits of a contract. We cannot predict what, if any, legislation will actually be proposed or enacted. Before making contributions to your contract or taking other action related to your contract, you should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract.

Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block]
Business disruption, cybersecurity, and artificial intelligence (“AI”) technologies risks
 
We rely heavily on technology, including interconnected computer systems and data storage networks and digital communications, to conduct our business. Because our business is highly dependent upon the effective operation of our computer systems and those of our service providers and other business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyberattacks. Cyberattacks may be systemic (e.g., affecting the internet, cloud services, or other infrastructure) or targeted (e.g., failures in or breach of our systems or those of third parties on whom we rely, including ransomware and malware attacks). Cybersecurity risks include, among other things, the loss, theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on our websites (or the websites of third parties on whom we rely), other operational disruption and unauthorized release, use or abuse of confidential customer information. The risk of cyberattacks may be higher during periods of geopolitical turmoil. Due to the increasing sophistication of cyberattacks, a cybersecurity breach could occur and persist for an extended period of time without detection. Systems failures and cyberattacks, as well as, any other catastrophic event, including natural and manmade disasters, public health emergencies, pandemic diseases, terrorist attacks, floods or severe storms affecting us, any third-party administrator, the underlying funds, intermediaries and other affiliated or third-party service providers may adversely affect us, our business operations and your account value and interfere with our ability to process contract transactions and calculate account values. Systems failures and cyberattacks may also interfere with our processing of contract transactions, including the processing of orders from our website or with the underlying funds, impact our ability to calculate account values and unit values and/or the underlying funds to be unable to calculate share values, cause the release or possible destruction of confidential customer and/or business information, impede order processing or cause other operational issues, subject us and/or our service providers and intermediaries to regulatory fines, litigation and financial losses and/or cause reputational damage. Cybersecurity risks may also impact the issuers of
securities in which the underlying funds invest, which may cause the underlying funds to lose value. The preventative actions we take to reduce the frequency and severity of cybersecurity incidents and protect our computer systems may be insufficient to prevent a cybersecurity breach from impacting our operations or your contract value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid cybersecurity breaches affecting your contract.
 
The development and deployment of AI tools and technologies, including generative AI, and its use and anticipated use by us or by third parties on whom we rely, may increase our existing operational risks or create new operational risks that we are not currently anticipating. AI and generative AI may be misused by us or by third parties upon which we rely, and that risk is increased by the relative newness of the technology, the speed at which it is being adopted, and the uncertain and evolving policy and regulatory landscape governing its use. Such misuse could expose us to legal or regulatory risk. Because the generative AI technology is so new, many of the potential risks of generative AI are currently unknowable.
 
In addition, we are also exposed to risks related to natural and man-made disasters, including, but not limited to, the occurrence of any storms, fires, floods, earthquakes, public health crises, malicious acts, and terrorist acts or any other event, which could adversely affect our ability to conduct business. A natural or man-made disaster, including a pandemic such as COVID-19, could result in our workforce, and/or employees of service providers and/or third-party administrators, being compromised and unable or unwilling to fully perform their responsibilities, which could likewise result in interruptions in our service. This could interfere with our processing of contract transactions, including processing orders from owners and orders with the underlying funds, impact our ability to calculate contract value, or have other adverse impacts on our operations. These events may also negatively affect our service providers and intermediaries, the underlying funds and issuers of securities in which the underlying funds invest, which may cause the funds underlying your contract to lose value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid negative impacts associated with natural and man-made disasters.

For example, if you make a withdrawal in the first year, you could pay a CWC of up to $6,000 on a $100,000 withdrawal.
 
For additional information about CWCs see “Contingent withdrawal charge” in “Charges and expenses” in this prospectus.
Are There Transaction Charges?

RISKS
Is There a Risk of Loss from Poor Performance?
 
Yes.
The contract is subject to the risk of loss. You could lose some or all of your account value depending on the investment options you choose.
 
For additional information about the risk of loss see “Principal risks of investing in the contract” in this prospectus.
Is this a Short-Term Investment?
 
No.
The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash because the contract is designed to provide for the accumulation of retirement savings and income on a long-term basis. As such, you should not use the contract as a short-term investment or savings vehicle. A withdrawal charge may apply in certain circumstances and any withdrawals may also be subject to federal and state income taxes and tax penalties.
 
For additional information about the investment profile of the contract see “Fee table” in this prospectus.
What Are the Risks Associated with the Investment Options?
 
An investment in the contract is subject to the risk of poor investment performance and can vary depending on the performance of the investment options available under the contract, (e.g., the Pooled Separate Accounts and the Portfolios). Each investment option, including the fixed investment options, has its own unique risks. You should review the investment options available under the contract before making an investment decision.
 
For additional information about the risks associated with investment options see “Investment options” and “Portfolios of the Trust” in “RIA Investment Options” and Appendix: “Investment Options Available Under the Contract” in this prospectus.
What Are the Risks Related to the Insurance Company?
 
An investment in the contract is subject to the risks related to the Company. Equitable Financial Life Insurance Company is solely responsible to the contract owner and participants for the contract’s account value. The general obligations under the contract, including the fixed investment options, are supported by our general account and are subject to our claims paying ability. An owner and participant should look solely to our financial strength for our claims-paying ability.

For additional information about insurance company risks see “About the general account” in “More information” in this prospectus.
Investment Restrictions [Text Block]
Yes.
The availability of investment options will vary by employer, and you should refer to your plan documents for a list of the investment options available to you. You may transfer accumulated amounts among the investment options under your contract at any time and in any amount, subject to certain transfer limitations described in this prospectus. We reserve the right to remove or substitute Portfolios and Pooled Separate Accounts as investment options.
 
For additional information about restrictions on the investment options see “Investment options” in “RIA Investment Options” and “Transferring your money among investment options” in this prospectus.
 
Transfers from the guaranteed interest option may be subject to limitations. From time to time, we may remove certain restrictions that apply to transferring amounts out of the guaranteed interest option. If we do so, we will tell you. We will also tell you at least 45 days in advance of the day that we intend to reimpose those transfer restrictions.
 
Contributions and transfers into and out of the guaranteed interest option are limited.
 
For additional information about the guaranteed interest option see “Guaranteed interest option” in “RIA Investment Options” in this prospectus.
Key Information, Benefit Restrictions [Text Block]
Yes.
Participant Loans. Not all employer plans will offer loans. Loans are subject to restrictions under federal tax rules and ERISA. Loans generally must be taken from the guaranteed interest option. The minimum loan amount is $1000 and the maximum loan amount is 90% of the balances attributable to the plan participant. We charge a 1% fee at the time a loan is made, and the employer plan may charge interest on the loan, at a rate they set. If a participant fails to repay a loan when due the amount of the unpaid balance may be treated as a withdrawal and as such, be subject to taxes, additional penalty taxes, and a CWC of up to 6% of the unpaid balance if this occurs within 9 years of the date on which the employer began it’s participation in the RIA. See “Participant Loans” in “Benefits Available Under the Contract” in this prospectus.
 
Optional Participant Recordkeeping Services. This service must be selected by the employer. If it is selected by the employer than the participants must be enrolled and pay the annual fee. Employers who did not elect the option may no longer do so.
Tax Implications [Text Block]
You should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract. There is no additional tax benefit to you if the contract is purchased through a tax-qualified plan or individual retirement account (IRA). Withdrawals will be subject to ordinary income tax and may be subject to tax penalties. Generally, you are not taxed until you make a withdrawal from the contract.
 
For additional information about tax implications see “Tax information” in this prospectus.
Investment Professional Compensation [Text Block]
Some financial professionals may receive compensation for selling the contract, both in the form of commissions or in the form of contribution-based compensation. Financial professionals may also receive additional compensation for enhanced marketing opportunities and other services (commonly referred to as “marketing allowances”). This conflict of interest may influence the financial professional to recommend this contract over another investment.
 
For additional information about compensation to financial professionals see “Distribution of the contracts” in “More information” in this prospectus.
Exchanges [Text Block]
Some financial professionals may have a financial incentive to offer a new contract in place of the one you already own. You should only exchange your contract if you determine, after comparing the features, fees, and risks of both contracts, as well as any fees or penalties to terminate your existing contract, that it is preferable to purchase the new contract rather than continue to own your existing contract.
 
For additional information about the charges you might incur in connection with an exchange see “Contingent withdrawal charge” in “Charges and expenses” in this prospectus.

Examples
 
These examples are intended to help you compare the cost of investing in the variable investment options with the cost of investing in other annuity contracts that offer variable investment options. These costs include transaction expenses, annual contract expenses, and annual Portfolio and Pooled Separate Account fees and expenses. These examples assume that no loans are taken. The first set of examples assumes you invest all of your account value in the most expensive underlying Portfolio. The second set of examples assumes you invest all of your account value in the most expensive Pooled Separate Account, the Alliance Bernstein Balanced Pooled Separate Account.
 
Separate Account No. 66 Variable Investment Options.
 The examples assume all account value is allocated to the variable investment options. Your costs could differ from those shown below if you invest in the fixed investment options.
 
These example assume that you invest $100,000 in the variable investment options for the time periods indicated. The examples also assume that your investment has a 5% return each year and assume the most expensive combination of annual portfolio expenses and the participant recordkeeping services available for an additional charge.

Portfolio Turnover
 
Each of the Pooled Separate Accounts pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual contract expenses or in the example, affect the Pooled Separate Account’s performance. During the most recent fiscal year, each Pooled Separate Account’s portfolio turnover rate as a percentage of the average value of its portfolio was:
 
   
AllianceBernstein Balanced — Separate Account No. 10
    
151.63
AllianceBernstein Common Stock — Separate Account No. 4

Item 5. Principal Risks [Line Items]  
Item 5. Principal Risks [Table Text Block]
3.
Principal Risks of Investing in the Contract
 
 
 
The risks identified below are the principal risks of investing in the contract. The contract may be subject to additional risks other than those identified and described in this prospectus.
 
Risks Associated with Variable Investment Options
and Pooled Separate Accounts
 
You take all the investment risk for amounts allocated to one or more of the investment options. If the investment options you select increase in value, then your account value goes up; if they decrease in value, your account value goes down. How much your account value goes up or down depends on the performance of the investment options in which you invest. We do not guarantee the investment results of any investment option. An investment in the contract is subject to the risk of poor investment performance, and the value of your investment can vary depending on the performance of the selected investment option, each of which has its own unique risks. You should review the variable investment options and Pooled Separate Accounts before making an investment decision.
 
Insurance Company Risk
 
No company other than Equitable Financial Life Insurance Company has any legal responsibility to pay amounts that we owe under the contract, including amounts allocated to the guaranteed interest option. The general obligations and any guaranteed interest option under the contract are supported by our general account and are subject to our claims paying ability. You should look solely to our financial strength for our claims-paying ability.
 
Possible Fees on Access to Account Value
 
We may apply fees if you access your account value during the accumulation period or surrender your contract. For example, in addition to possible tax consequences you may incur fees for accessing your account value such as a withdrawal charge and/or a charge for any optional benefits, if applicable.
 
Limitations on Access to Account Value Through Withdrawals
 
We may impose a contingent withdrawal charge (“CWC”) against withdrawals made from any of the Pooled Separate Accounts, Variable Investment options or the guaranteed interest option at any time up to and including the ninth anniversary of the date on which the employer plan began its participation in RIA. Withdrawals are generally subject to federal and state income tax, and may be subject to tax penalties if taken before age 59 1/2. Additionally, there could be a delay in withdrawals from the guaranteed interest option of up to 5 years.
Possible Adverse Tax Consequences
 
The tax considerations associated with the contract vary and can be complicated. The applicable tax rules can differ, depending on the type of plan. We cannot provide detailed information on all tax aspects of the contract. Moreover, the tax aspects that apply to a particular person’s contract may vary depending on the facts applicable to that person. Tax rules may change without notice. We cannot predict whether, when, or how these rules could change. Any change could affect contracts purchased before the change. Congress may also consider further proposals to comprehensively reform or overhaul the United States tax and retirement systems, which if enacted, could affect the tax benefits of a contract. We cannot predict what, if any, legislation will actually be proposed or enacted. Before making contributions to your contract or taking other action related to your contract, you should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract.
 
Not a Short-Term Investment
 
The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash because the contract is designed to provide for the accumulation of retirement savings and income on a long-term basis. As such, you should not use the contract as a short-term investment or savings vehicle and you should consider whether investing in the contract is consistent with the purpose for which the investment is being considered.
 
Risk of Loss
 
All investments have risks to some degree and it is possible that you could lose money by investing in the contract. An investment in the contract is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
 
Risk Associated with Taking a Loan
 
Loans will decrease your account value and death benefit, and loaned amounts will not participate in the investment experience of your investment options. There may be adverse tax consequences associated with taking a loan from your contract.
 
Contract Changes Risk
 
We may, at any time, exercise our rights to limit or terminate your contributions, allocations and transfers to any of the variable investment options. We reserve the right, subject to compliance with laws that apply, to remove variable investment options from the Separate Account, to combine any two or more variable investment options, to restrict or eliminate any voting rights as to the Separate Account, to
 
limit or terminate contributions or transfers into any of the variable investment options, and to limit the number of variable investment options you may select.
 
You should evaluate whether our ability to make the changes described above, and your ability to react to such changes, are appropriate based on your investment goals. When such changes occur, you should also evaluate whether those changes are appropriate based on your investment goals and, if not, you should evaluate your options under the Contract, which may be limited and may have negative consequences associated with them, as described in this prospectus.
 
Business disruption, cybersecurity, and artificial intelligence (“AI”) technologies risks
 
We rely heavily on technology, including interconnected computer systems and data storage networks and digital communications, to conduct our business. Because our business is highly dependent upon the effective operation of our computer systems and those of our service providers and other business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyberattacks. Cyberattacks may be systemic (e.g., affecting the internet, cloud services, or other infrastructure) or targeted (e.g., failures in or breach of our systems or those of third parties on whom we rely, including ransomware and malware attacks). Cybersecurity risks include, among other things, the loss, theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on our websites (or the websites of third parties on whom we rely), other operational disruption and unauthorized release, use or abuse of confidential customer information. The risk of cyberattacks may be higher during periods of geopolitical turmoil. Due to the increasing sophistication of cyberattacks, a cybersecurity breach could occur and persist for an extended period of time without detection. Systems failures and cyberattacks, as well as, any other catastrophic event, including natural and manmade disasters, public health emergencies, pandemic diseases, terrorist attacks, floods or severe storms affecting us, any third-party administrator, the underlying funds, intermediaries and other affiliated or third-party service providers may adversely affect us, our business operations and your account value and interfere with our ability to process contract transactions and calculate account values. Systems failures and cyberattacks may also interfere with our processing of contract transactions, including the processing of orders from our website or with the underlying funds, impact our ability to calculate account values and unit values and/or the underlying funds to be unable to calculate share values, cause the release or possible destruction of confidential customer and/or business information, impede order processing or cause other operational issues, subject us and/or our service providers and intermediaries to regulatory fines, litigation and financial losses and/or
cause reputational damage. Cybersecurity risks may also impact the issuers of securities in which the underlying funds invest, which may cause the underlying funds to lose value. The preventative actions we take to reduce the frequency and severity of cybersecurity incidents and protect our computer systems may be insufficient to prevent a cybersecurity breach from impacting our operations or your contract value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid cybersecurity breaches affecting your contract.
 
The development and deployment of AI tools and technologies, including generative AI, and its use and anticipated use by us or by third parties on whom we rely, may increase our existing operational risks or create new operational risks that we are not currently anticipating. AI and generative AI may be misused by us or by third parties upon which we rely, and that risk is increased by the relative newness of the technology, the speed at which it is being adopted, and the uncertain and evolving policy and regulatory landscape governing its use. Such misuse could expose us to legal or regulatory risk. Because the generative AI technology is so new, many of the potential risks of generative AI are currently unknowable.
 
In addition, we are also exposed to risks related to natural and man-made disasters, including, but not limited to, the occurrence of any storms, fires, floods, earthquakes, public health crises, malicious acts, and terrorist acts or any other event, which could adversely affect our ability to conduct business. A natural or man-made disaster, including a pandemic such as COVID-19, could result in our workforce, and/or employees of service providers and/or third-party administrators, being compromised and unable or unwilling to fully perform their responsibilities, which could likewise result in interruptions in our service. This could interfere with our processing of contract transactions, including processing orders from owners and orders with the underlying funds, impact our ability to calculate contract value, or have other adverse impacts on our operations. These events may also negatively affect our service providers and intermediaries, the underlying funds and issuers of securities in which the underlying funds invest, which may cause the funds underlying your contract to lose value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid negative impacts associated with natural and man-made disasters.

Participant Recordkeeping Services
 
Services provided. 
If your employer elected the participant recordkeeping services program (“PRS”), we:
 
  establish an individual participant account for each participant covered by your employer’s plan based on data your employer provides;
 
  receive and deposit contributions on behalf of participants to individual participant accounts;
 
  maintain records reflecting, for each participant, contributions, transfers, loan transactions, withdrawals and investment experience and interest accrued, as applicable, on an individual participant’s proportionate values in the plan;
 
  provide to your employer individual participant’s reports reflecting the activity in the individual participant’s proportionate interest in the plan; and
 
  process transfers and distributions of the participant’s portion of his or her share of the employer plan assets among the investment options as your employer instructs.
 
Your employer is responsible for providing the Company with required information and for complying with our procedures relating to the PRS program. We will not be liable for errors in recordkeeping if the information your employer provides is not provided on a timely basis or is incorrect. The plan administrator retains full responsibility for the income tax withholding and reporting requirements including required notices to the plan participants, as set forth in the federal income tax rules and applicable Treasury Regulations.
 
The Company does not keep records or provide individual reports for individual participants for plans that do not elect PRS.
 
Investment options. 
Your employer must include the guaranteed interest option in the investment options.
 
Fees. 
We charge an annual fee of $25 per active participant paid in twelve equal monthly installments of $2.08. We deduct the fee from the amounts attributable to each individual participant at the end of each month by means of a reduction of units or a cash withdrawal from the guaranteed interest option. We retain the right to change the fee upon 30 days’ notice to the employer. See “Charges and expenses” in this prospectus.
 
Enrollment. 
Enrollment of your plan in PRS is no longer available.
 
Participant Loans
 
Loans to plan trustees on behalf of participants are permitted in our RIA program. It is the plan administrator’s responsibility to administer the loan program.
 
The following are important features of the RIA loan provision:
 
  We will only permit loans from the guaranteed interest option. If the amount requested to be borrowed plus the loan fee and loan reserve we discuss below is more than the amount available in the guaranteed interest option for the loan transaction, the employer can move the additional amounts necessary from one or more Pooled Separate Accounts or the variable investment options to the guaranteed interest option.
 
  The plan administrator determines the interest rate, the maximum term and all other terms and conditions of the loan.
 
  Repayment of loan principal and interest can be made only to the guaranteed interest option. The employer must identify the portion of the repayment amount which is principal and which is interest.
 
  Upon repayment of a loan amount, any repayment of loan principal and loan reserve (see below) taken from one or more Pooled Separate Accounts or the variable investment options for loan purposes may be moved back to a Pooled Separate Account or the variable investment option.
 
  We charge a loan fee in an amount equal to 1% of the loan principal amount on the date a loan is made. The contingent withdrawal charge will be applied to any unpaid principal, as if the amount had been withdrawn on the day the principal payment was due, and taxes and additional penalty taxes may also apply. See “Charges and expenses” in this prospectus.
 
  The minimum amount of a loan for a participant is $1,000, and the maximum amount is 90% of the balances in all the investment options for a participant, subject to the maximum loan amount permitted by the employer’s plan and the Code.
 
  On the date a loan is made, we create a loan reserve account in the guaranteed interest option in an amount equal to 10% of the loan amount. The 10% loan reserve is intended to cover (1) the ongoing operations fee applicable to amounts borrowed, (2) the possibility of our having to deduct applicable contingent withdrawal charges (see “Charges and expenses” in this prospectus) and (3) the deduction of any other withholdings, if required. The loan amount will not earn any interest under the contracts while the loan is outstanding but the plan administrator may charge interest on the loan amount at a rate they set. The amount of the loan reserve will continue to earn interest at the guaranteed interest option rate applicable for the employer plan.
 
  Amounts borrowed from your contract do not participate in separate account investment experience and therefore, loans can affect the account value whether or not you repay the loan. The account value when you surrender, die, or terminate your contract will be reduced by the amount of any outstanding loan plus accrued interest.
 
  The ongoing operations fee will apply to the sum of the investment option balances (including the loan reserve) plus any unpaid loan principal. If the employer plan is terminated or any amount is withdrawn, or if any withdrawal from RIA results in the reduction of the 10% loan reserve amount in the guaranteed interest option, during the time a loan is outstanding, the contingent withdrawal charge will be applied to any principal loan balances outstanding as well as to any employer plan balances (including the loan reserve) in the investment options. See “Charges and expenses” in this prospectus.

Possible Adverse Tax Consequences
 
The tax considerations associated with the contract vary and can be complicated. The applicable tax rules can differ, depending on the type of plan. We cannot provide detailed information on all tax aspects of the contract. Moreover, the tax aspects that apply to a particular person’s contract may vary depending on the facts applicable to that person. Tax rules may change without notice. We cannot predict whether, when, or how these rules could change. Any change could affect contracts purchased before the change. Congress may also consider further proposals to comprehensively reform or overhaul the United States tax and retirement systems, which if enacted, could affect the tax benefits of a contract. We cannot predict what, if any, legislation will actually be proposed or enacted. Before making contributions to your contract or taking other action related to your contract, you should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract.
C000050399 [Member] | Business disruption, cybersecurity, and artificial intelligence (AI) technologies risks [Member]  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block]
Business disruption, cybersecurity, and artificial intelligence (“AI”) technologies risks
 
We rely heavily on technology, including interconnected computer systems and data storage networks and digital communications, to conduct our business. Because our business is highly dependent upon the effective operation of our computer systems and those of our service providers and other business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyberattacks. Cyberattacks may be systemic (e.g., affecting the internet, cloud services, or other infrastructure) or targeted (e.g., failures in or breach of our systems or those of third parties on whom we rely, including ransomware and malware attacks). Cybersecurity risks include, among other things, the loss, theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on our websites (or the websites of third parties on whom we rely), other operational disruption and unauthorized release, use or abuse of confidential customer information. The risk of cyberattacks may be higher during periods of geopolitical turmoil. Due to the increasing sophistication of cyberattacks, a cybersecurity breach could occur and persist for an extended period of time without detection. Systems failures and cyberattacks, as well as, any other catastrophic event, including natural and manmade disasters, public health emergencies, pandemic diseases, terrorist attacks, floods or severe storms affecting us, any third-party administrator, the underlying funds, intermediaries and other affiliated or third-party service providers may adversely affect us, our business operations and your account value and interfere with our ability to process contract transactions and calculate account values. Systems failures and cyberattacks may also interfere with our processing of contract transactions, including the processing of orders from our website or with the underlying funds, impact our ability to calculate account values and unit values and/or the underlying funds to be unable to calculate share values, cause the release or possible destruction of confidential customer and/or business information, impede order processing or cause other operational issues, subject us and/or our service providers and intermediaries to regulatory fines, litigation and financial losses and/or
cause reputational damage. Cybersecurity risks may also impact the issuers of securities in which the underlying funds invest, which may cause the underlying funds to lose value. The preventative actions we take to reduce the frequency and severity of cybersecurity incidents and protect our computer systems may be insufficient to prevent a cybersecurity breach from impacting our operations or your contract value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid cybersecurity breaches affecting your contract.
 
The development and deployment of AI tools and technologies, including generative AI, and its use and anticipated use by us or by third parties on whom we rely, may increase our existing operational risks or create new operational risks that we are not currently anticipating. AI and generative AI may be misused by us or by third parties upon which we rely, and that risk is increased by the relative newness of the technology, the speed at which it is being adopted, and the uncertain and evolving policy and regulatory landscape governing its use. Such misuse could expose us to legal or regulatory risk. Because the generative AI technology is so new, many of the potential risks of generative AI are currently unknowable.
 
In addition, we are also exposed to risks related to natural and man-made disasters, including, but not limited to, the occurrence of any storms, fires, floods, earthquakes, public health crises, malicious acts, and terrorist acts or any other event, which could adversely affect our ability to conduct business. A natural or man-made disaster, including a pandemic such as COVID-19, could result in our workforce, and/or employees of service providers and/or third-party administrators, being compromised and unable or unwilling to fully perform their responsibilities, which could likewise result in interruptions in our service. This could interfere with our processing of contract transactions, including processing orders from owners and orders with the underlying funds, impact our ability to calculate contract value, or have other adverse impacts on our operations. These events may also negatively affect our service providers and intermediaries, the underlying funds and issuers of securities in which the underlying funds invest, which may cause the funds underlying your contract to lose value. There can be no assurance that we or the underlying funds or our service providers and intermediaries will be able to avoid negative impacts associated with natural and man-made disasters.

Risks Associated with Variable Investment Options
and Pooled Separate Accounts
 
You take all the investment risk for amounts allocated to one or more of the investment options. If the investment options you select increase in value, then your account value goes up; if they decrease in value, your account value goes down. How much your account value goes up or down depends on the performance of the investment options in which you invest. We do not guarantee the investment results of any investment option. An investment in the contract is subject to the risk of poor investment performance, and the value of your investment can vary depending on the performance of the selected investment option, each of which has its own unique risks. You should review the variable investment options and Pooled Separate Accounts before making an investment decision.
