DATA PAGE

CONTRACT DATA

Nonforfeiture Value: The Nonforfeiture Value is equal to 87.50% of the Premium Payments made, accumulated at the applicable Nonforfeiture Rate since the Contract Date, minus any amounts surrendered, accumulated at the applicable Nonforfeiture Rate since the date of Surrender. The Nonforfeiture Value only applies to the Initial Holding Account and Fixed Segment Options, if any.

The Nonforfeiture Rate will be calculated at the beginning of each calendar quarter by taking an average of selected 5-year Constant Maturity Treasury (CMT) rates, less 1.25%, rounded to the nearest 0.05%. The Nonforfeiture Rate will be no less than 0.15%, and no greater than 3.00%.

The CMT rates for six calendar months will be selected as the averaging period for Nonforfeiture Rate calculations. The averaging period will begin with the ninth calendar month prior to the beginning of the next calendar quarters and will end with the fourth calendar month prior to the beginning of the next calendar quarter. For example, the Nonforfeiture Rate for the calendar quarter beginning January 1 would be the average of the 5-year CMT rates during the months of April through September of the prior year.

The Nonforfeiture Rate implemented for any calendar quarter will be updated to reflect the most recent calculation only if the calculation results in a Nonforfeiture Rate that is more than 0.25% different, higher or lower, from the actual Nonforfeiture Rate applicable in the most recently concluded calendar quarter. We will automatically reset the Nonforfeiture Rate for calendar quarters beginning January 1 and July 1 equal to the actual calculation associated with that time.

[SG Smart Climate

The SG Smart Climate Index (Bloomberg Ticker: SGIXSMAC) is a rules-based index that aims to provide investment exposure to the performance of stocks of U.S. large-capitalization companies that are selected based on proprietary climate risk preparedness scores and certain environmental, social, and governance (ESG) exclusion filters. Climate risk generally refers to the risk of negative impacts on a company’s business or financial condition due to climate-related conditions around the globe or the transition to a lower carbon economy. The climate risk models used in connection with the Index seek to identify large U.S. companies that are more likely to perform well in future climate scenarios.

The Index is an “excess return” index. The Index’s return reflects the total return on an investment in the underlying component stocks (including reinvestment of all dividends, interest, and other income), less certain negative adjustments and deductions that reduce the performance of the Index. See “Performance Drags” below.

The sponsor of the Index and the Underlying SGI Index (as defined below) is Société Générale. The index calculator is S&P Opco, LLC (a subsidiary of S&P Dow Jones Indices LLC). The climate risk models used in connection with the Index are produced by Entelligent, Inc. Sustainalytics provides the data used to support the ESG exclusion filters. None of these companies are affiliated with Principal.]
