Effective as of the date of this supplement,

Appendix A: Investment Options Available Under the Contract

(“Appendix A”) in the prospectus and the updating summary prospectus is deleted and replaced with the following Appendix A to reflect changes to the footnotes addressing the availability of certain strategies in

California

.

APPENDIX A: INVESTMENT OPTIONS AVAILABLE UNDER THE CONTRACT

The following is a list of Indexed Strategies currently available under the Contract. We may change the features of the Indexed Strategies listed below (including the Index and the current limits on Index gains and losses), offer new Indexed Strategies, and terminate existing Indexed Strategies. We will provide you with written notice before making any changes other than changes to current limits on Index gains. Information about current limits on Index gains is available at

www.massmutualascend.com/index-frontier-5-plus

. For additional information about the features of the Indexed Strategies, please see the “Indexed Strategies” section in the prospectus. The practical availability of investment options at the time of sale may vary depending on the broker-dealer through which the Contract is sold. See Appendix D – Financial Intermediary Variations in the prospectus.

Note: If amounts are removed from an Indexed Strategy before the end of its Term, we will apply a Daily Value Percentage adjustment. This may result in a significant reduction in your Strategy value that could exceed any protection from Index loss that would be in place if you held the Indexed Strategy until the end of the Term. You may not be able to invest in certain Indexed Strategies, as noted below.

The

S&P 500

is a “price return index,” not a “total return index,” and therefore does not reflect dividends paid on the securities composing the Index. This will reduce the Index return and cause the Index to underperform a direct investment in the securities composing the Index.

The

iShares MSCI EAFE ETF

deducts fees and costs when calculating Index performance. This will reduce the ETF’s return and cause the ETF to underperform a direct investment in the securities composing the ETF.

The

iShares US Real Estate ETF

deducts fees and costs when calculating Index performance. This will reduce the ETF’s return and cause the ETF to underperform a direct investment in the securities composing the ETF.

The

SPDR Gold Shares ETF

deducts fees and costs when calculating Index performance. This will reduce the ETF’s return and cause the ETF to underperform a direct investment in gold bullion.

The

First Trust Barclays Edge

is an “excess return index” that subtracts a risk-free interest rate from the price and dividend return of the securities. It also deducts fees and costs when calculating Index performance. This will reduce the Index’s return and cause the Index to underperform a direct investment in the securities composing the Index.
