Appendix A — Investment Options Available Under The Contract

Indexed Accounts

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

Note: If amounts are removed from an Indexed Account before the end of its Indexed Term, we will apply a Contract Adjustment based on Interim Value. This may result in significant reduction in your Contract Value that could exceed any protection from Index loss that would be in place if you held the Indexed Segment until the end of the Indexed Term. See Indexed Accounts – Interim Value in the prospectus for additional details.

1 The Index 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 may cause the Index to underperform a direct investment in the securities composing the Index.

2 This Indexed Account provides total protection from Index losses at the end of the Indexed Term.

The Capital Strength Net Fee IndexSM and First American Trust Leadership IndexTM deduct fees and costs when calculating Index performance which will reduce the Index return and cause each Index to underperform a direct investment in the securities composing the Index.

Each Indexed Account’s limit on Index losses is guaranteed not to change for as long as that Indexed Account remains available under the Contract. We will not offer a 1-Year Indexed Account with a Performance Cap, Performance Trigger, or Dual Performance Trigger below 1.00% (except in the case of the 100% Protection Level, which has a minimum Performance Cap of 0.10%) or a 6-Year Annual Lock Indexed Account with a Performance Cap below 1.00%. We will not offer a 6-Year Performance Cap below 10% on a Performance Cap Indexed Account, or below 15% on a Dual15 Plus Indexed Account. We will not offer a 3-Year or 6-Year Participation Rate Indexed Account with a Participation Rate below 15%. We will not offer a Spread Rate Indexed Account with a Spread Rate greater than 25%. However, we reserve the right to add and remove Indexed Accounts and to offer Indexed Accounts with different Crediting Methods or Protection Methods. As such, the limits on Index loss offered under the Contract may change from one Indexed Term to the next. We do not guarantee that the Contract will always offer Indexed Accounts that limit Index losses. See Indexed Accounts in the prospectus for additional details.
