RISKS

LOCATION IN PROSPECTUS

Risk of Loss

You can lose money by investing in the Contract, including loss of principal.

Principal Risks of Investing in the Contract

Not a Short-Term Investment

The Contract is not designed for short-term investing and is not appropriate for an investor who needs ready access to cash.

CDSCs may apply for up to seven years following your last Purchase Payment.

If CDSCs apply, they will reduce the value of your Contract if you withdraw money during the  CDSC period. The benefits of tax deferral also mean the Contract is more beneficial to investors with a long time horizon.

Principal Risks of Investing in the Contract

Risks Associated with Investment Options

An investment in the Contract is subject to the risk of poor investment performance of the Funds you choose and can vary depending upon the performance of the Funds available under the Contract.

Each Fund has its own unique risks.

You should review the prospectuses for the available Funds before making an investment decision.

Principal Risks of Investing in the Contract

Insurance Company Risks

Any obligations (including under any fixed account investment option), guarantees, and benefits of the Contract are subject to the claims-paying ability of MassMutual. If MassMutual experiences financial distress, it may not be able to meet its obligations to you. More information about MassMutual, including its financial strength ratings, is available at www.MassMutual.com/ratings.

RESTRICTIONS

LOCATION IN PROSPECTUS

Investments

MassMutual reserves the right to remove or substitute Funds as investment options available under the Contract.

We reserve the right to limit transfers if frequent or large transfers occur.

General Information about Massachusetts Mutual Life Insurance Company, the Separate Account and the Investment Choices – The Funds
Transfers and Transfer Programs – Limits on Frequent Trading and Market Timing Activity

Optional Benefits

Your Contract will be subject to investment allocation restrictions while RetirePay is in effect. This means you will be limited in your choice of Sub-Account investments, and may be limited in how much you can invest in certain Sub-Accounts. We impose these allocation restrictions to reduce the risk of investment losses that may require us to use our General Account assets to honor the guarantee under RetirePay.

Withdrawals that are prior to the Guaranteed Lifetime Withdrawal Date are Excess Withdrawals. On or after the Guaranteed Lifetime Withdrawal Date, the portion of a withdrawal (including CDSCs) from the Contract Value that causes the cumulative withdrawals to exceed the Annual Lifetime Benefit Amount in that Contract Year will be an Excess Withdrawal unless the withdrawal is taken as a part of the Company’s Systematic Withdrawal Program established for the payment of RMDs, under which the RMD is calculated by the Company and no other withdrawals are taken within the Contract Year. Any withdrawal that occurs after the cumulative withdrawals exceed the Annual Lifetime Benefit Amount in that Contract Year will also be an Excess Withdrawal. Excess Withdrawals can result in a significant reduction of your Benefit Base, depending upon the amount of the withdrawal.

You may not make additional Purchase Payments that total more than $10,000 in a Contract Year after the first Contract Year while RetirePay is in effect. You may not make additional Purchase Payments on or after the Guaranteed Lifetime Withdrawal Date while RetirePay is in effect or after you elect the RetirePay Charge Increase Opt-Out.

TAXES

LOCATION IN PROSPECTUS

Tax Implications

You should consult with a tax professional to determine the tax implications of an investment in and payments received under the Contract.

If you purchase the Contract through a qualified retirement plan or individual retirement annuity (IRA), you do not receive any additional tax benefit.

Earnings on your Contract are taxed at ordinary income tax rates when you withdraw them, and you may have to pay an additional income tax if you take a withdrawal before age 59½. Earnings for this purpose consist of Contract Value in excess of your after-tax investment in the Contract.

Taxes

CONFLICTS OF INTEREST

LOCATION IN PROSPECTUS

Investment Professional Compensation

Your registered representative may receive compensation, in the form of commissions, for selling the Contract to you. If your registered representative is also a MassMutual insurance agent, they are also eligible for certain cash and non-cash benefits from MassMutual. Cash compensation includes bonuses and allowances based on factors such as sales, productivity and persistency (contract retention). Non-cash compensation includes various recognition items such as prizes and awards as well as attendance at, and payment of the costs associated with attendance at, conferences, seminars and recognition trips, and also includes contributions to certain individual plans such as pension and medical plans. Sales of the Contract may help these registered representatives and their supervisors qualify for such benefits.

This conflict of interest may influence your registered representative to offer or recommend the Contract over another investment.

Distribution

Exchanges

In general you should be aware that some investment professionals may have a financial incentive to offer you a new contract in place of the one you already own. Thus, in general, you should only exchange your annuity contract if you determine, after comparing the features, fees, and risks of both contracts, that it is preferable for you to purchase the new annuity rather than continue to own the existing annuity.

(*) These Funds and their investment advisers have entered into contractual fee waivers or expense reimbursements. These temporary fee reductions are reflected in their current expenses. Those contractual arrangements are designed to reduce the Fund’s total current expenses for Owners and will continue past the current year.
(1) These are fund-of-funds investment choices. They are known as fund-of-funds because they invest in other underlying funds. A fund offered in a fund-of-funds structure may have higher expenses than a direct investment in its underlying funds because a fund-of-funds bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.
(2) You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. The yield of this Fund may become very low during periods of low interest rates. After deduction of Separate Account charges, the yield in the division that invests in this Fund could be negative.
(3) American Funds Insurance Series® Washington Mutual Investors Fund was added as an investment option on April 29, 2024.
(4) Columbia Variable Portfolio - Contrarian Core Fund was added as an investment option on April 29, 2024.
(5) Macquarie VIP Growth Series was added as an investment option on April 29, 2024.
(6) The Fund is a “feeder” fund, meaning that it does not buy investment securities directly, but instead invests in shares of a corresponding “master” fund, which in turn purchases investment securities. A fund offered in a master feeder structure may have higher expenses than those of a fund which invests directly in securities because the “feeder” fund bears its own expenses in addition to those of the “master” fund. You should read the Fund prospectuses for more information about this “feeder” fund.
(7) The MML American Funds Growth Fund invests all of its assets in the Class 1 shares of the American Funds Insurance Series® – Growth Fund. However, this Fund is not available directly as investment choices under your MassMutual variable product. You should read the prospectus along with the prospectus for the MML American Funds Growth Fund.
(8) Janus Henderson Enterprise Portfolio was added as an investment option on April 29, 2024.
(9) American Funds Insurance Series® Global Small Capitalization Fund was added as an investment option on April 29, 2024.
(10) American Funds Insurance Series® New World Fund® was added as an investment option on April 29, 2024.
(11) Janus Henderson Overseas Portfolio was added as an investment option on April 29, 2024.
(12) Specialty funds are an all-encompassing category that consists of funds that forgo broad diversification to concentrate on a certain segment of the economy or a specific targeted strategy. For example, sector funds are targeted strategy funds aimed at specific sectors of the economy, such as financial, technology, healthcare, and so on. Sector funds can, therefore, be more volatile than a more diversified equity fund since the stocks in a given sector tend to be highly correlated with each other.
(13) Macquarie VIP Asset Strategy Series formerly known as Delaware Ivy VIP Asset Strategy.

(14) Vest US Large Cap 10% Buffer Strategies VI Fund formerly known as Cboe Vest US Large Cap 10% Buffer Strategies VI Fund.
(15) Buffer funds employ a strategy to provide buffer protection, which includes a capped upside return risk and an outcome period risk. These strategies could limit the upside participation of the fund in rising equity markets relative to other funds and provide limited protection in the event of a market downturn. This may conflict with your investment objectives by limiting your ability to maximize growth of your Contract Value. For more information about the risks associated with buffer funds, please see “Principal Risks of Investing in the Contract – Defined Outcome Funds Risk” in the statutory prospectus. This fund is not available for policies issued in New York.
