Limited Availability

This Strategy is only available for Terms that begin before the end of the fourth Contract Year.

Gain or Loss

Each day, the value of the Strategy includes the Gain or Loss for the Term.

Gain or Loss is calculated as a percentage of the then remaining investment base of the Strategy for the current Term. For this purpose, the investment base is equal to:

 

  1)

the amount applied to this Strategy at the start of the Term; minus

 

  2)

the amount deducted from the investment base for each withdrawal or charge that is taken from this Strategy during the Term.

Gain or Loss at the End of a Term

After the final Market Close of a Term, unless you have elected a Performance Lock, any Gain or Loss is determined based on the increase or decrease in the S&P 500 Index since the start of the Term. This increase or decrease is expressed as a percentage of the value of the S&P 500 Index at the start of the Term. It is measured from the Index value at the last Market Close on or before the first day of the Term to the Index value at the final Market Close of the Term. The Index value is the standard industry value of the S&P 500 Index.

If the S&P 500 Index has decreased, then the Loss for the Term is equal to the percentage decrease in the Index, but only to the extent such decrease exceeds the 20% Buffer.

If the S&P 500 Index has increased and the Term does not have a Cap, then the Gain for the Term is equal to the percentage increase in the Index, multiplied by the Upside Participation Rate.

If the S&P 500 Index has increased and the Term has a Cap, then the Gain for the Term is equal to the lesser of:

 

  1)

the percentage increase in the Index, multiplied by the Upside Participation Rate; or

 

  2)

the Cap.

The Gain or Loss for the Term is illustrated below:

 

Percentage Change in Index for the Term

   Gain or Loss for Term

Decrease of more than 20%

   Loss equal to percentage decrease in Index over 20%

Decrease of 20% or less

   No Gain or Loss

No increase or decrease

   No Gain or Loss

Increase if no Cap, or increase of less than Adjusted Cap

   Gain equal to percentage increase in Index multiplied by Upside Participation Rate

Increase of equal to or greater than Adjusted Cap

   Gain equal to the Cap

Gain or Loss before the End of a Term

Before the final Market Close of a Term, unless you have elected a Performance Lock, the Gain or Loss for the Term is equal to the Daily Value Percentage.

 

ICC25-E1861925NW    2    [XX]


Performance Lock

A Performance Lock is an election to lock in the Gain or Loss for the remainder of a Term. You may make a Performance Lock election for a Term by a Request in Good Order. Once we receive your Request in Good Order, a Performance Lock election for a Term cannot be changed or revoked.

A Performance Lock election for a Term is effective on the second Market Close following our receipt of your Request in Good Order. After the second Market Close, the Gain or Loss before the end of the Term and the Gain or Loss at the end of the Term is equal to the Daily Value Percentage as determined for that second Market Close.

If you elect a Performance Lock, the Term will end on the earliest anniversary of the Term start date that is on or after the date that the Performance Lock is effective.

Daily Value Percentage

The Daily Value Percentage is equal to:

 

  1)

the Net Option Price for the Strategy as of the most recent Market Close of the Term; minus

 

  2)

the Residual Option Cost as of the most recent Market Close of the Term; and minus

 

  3)

the Trading Cost.

Net Option Price

If a Term does not have a Cap, then the Net Option Price as of a Market Close is a percentage equal to:

 

  1)

the ATM Call Option price calculated for the Market Close, multiplied by the Upside Participation Rate; minus

 

  2)

the OTM Put Option price calculated for the Market Close.

If a Term has a Cap, then the Net Option Price as of a Market Close is a percentage equal to:

 

  1)

the ATM Call Option price calculated for the Market Close, multiplied by the Upside Participation Rate; minus

 

  2)

the OTM Call Option price calculated for the Market Close, multiplied by the Upside Participation Rate; and minus

 

  3)

the OTM Put Option price calculated for the Market Close.

Residual Option Cost

The Residual Option Cost is a percentage equal to:

 

  1)

the Net Option Price for the Strategy calculated for the beginning of the Term; multiplied by

 

  2)

the number of days remaining until the final Market Close of the Term divided by 1096.

Trading Cost

The Trading Cost is the estimated cost of selling the hypothetical option before the end of a Term to the extent that such cost is not already reflected in the Option Prices. It is a percentage set by us from time to time to reflect the average difference between the Option Prices and market bid prices.

ATM Call Option

The ATM Call Option is a hypothetical call option that will pay the holder an amount equal to the percentage increase, if any, in the S&P 500 Index from the last Market Close on or before the start of the Term to the final Market Close of the Term.

OTM Call Option

The OTM Call Option is a hypothetical call option that will pay the holder an amount equal to the percentage increase, if any, in the S&P 500 Index from the last Market Close on or before the start of the Term to the final Market Close of the Term, but only to the extent the percentage increase exceeds the Adjusted Cap for the Term.

 

ICC25-E1861925NW    3    [XX]


OTM Put Option

The OTM Put Option is a hypothetical put option that will pay the holder an amount equal to the percentage decrease, if any, in the S&P 500 Index from the last Market Close on or before the start of the Term to the final Market Close of the Term, but only to the extent the percentage decrease exceeds the Buffer for the Term.

Option Prices

The ATM Call Option, OTM Call Option, and OTM Put Option prices are calculated by us using an option pricing model for valuing an option. The price of each option is stated as a percentage of the value of the S&P 500 Index at the last Market Close on or before the first day of the Term.

Buffer

The Buffer is the decrease in the value of the S&P 500 Index for a Term that is disregarded when determining the Loss for the Term. The Buffer for each Term of this Strategy is 20%.

Upside Participation Rate

The Upside Participation Rate is the portion of the increase in the S&P 500 Index for a Term taken into account when determining the Gain for the Term. We will set the Upside Participation Rate for each initial or renewal Term of this Strategy before the first day of that Term. For a given Term, we may set a different Upside Participation Rate for amounts attributable to Purchase Payments received on different dates. The Upside Participation Rate for each Term of this Strategy shall never be less than the minimum shown in the Endorsement Specifications.

Cap

The Cap is the largest possible Gain for the Term. We may set a Cap for any initial or renewal Term of this Strategy. If we set a Cap for a Term of this Strategy, we will set the Cap before the first day of that Term. For a given Term, we may set a different Cap for amounts attributable to Purchase Payments received on different dates. A Cap for each Term of this Strategy shall never be less than the minimum shown in the Endorsement Specifications.

Adjusted Cap

The Adjusted Cap is the largest increase in the S&P 500 Index for a Term taken into account, when determining the Gain for the Term. It is equal to the Cap for the Term divided by the Upside Participation Rate for the Term.

Merger of Crediting Strategies

At the end of a Term, if a new Term of this Strategy is not available, this Strategy shall merge into and become a part of the S&P 500 1-Year Indexed Strategy designated by the Company on a nondiscriminatory basis. Unless moved under the reallocation provision of the Contract, the value of this Strategy at the end of a Term shall be applied to a new Term of such S&P 500 1-Year Indexed Strategy.
