Each Reorganization contemplates: (1) the transfer of all of the assets of an Acquired Fund to the corresponding Acquiring Fund in exchange for shares of the corresponding Acquiring Fund that have an aggregate net asset value equal to the aggregate net asset value of the shares of the Acquired Fund as of the close of business on the Reorganization Date; (2) the assumption by the corresponding Acquiring Fund of all of the liabilities of the Acquired Fund; and (3) the distribution of shares of the corresponding Acquiring Fund to the shareholders of the Acquired Fund in complete liquidation of the Acquired Fund. Each shareholder of an Acquired Fund will receive shares of the corresponding Acquiring Fund of the same class, and in equal value to, the shares of the Acquired Fund held by that shareholder as of the close of business on the Reorganization Date. Each Reorganization does not require shareholder approval.

Due to the Reorganizations, as of the close of business on the Closing Dates listed above, you will no longer be able to allocate new Premium Payments or make transfers to the Acquired Fund Sub-Accounts, including by way of program trades (identified below).

As a result of the Reorganizations, as of the close of business on the applicable Reorganization Date:

(i) if any of your Contract Value is currently invested in one of the Acquired Fund Sub-Accounts, that Contract Value will be transferred into the corresponding Acquiring Fund Sub-Account;

(ii) unless you direct us otherwise, if any portion of your future Premium Payments is allocated to one of the Acquired Fund Sub-Accounts, those future payments will automatically be allocated to the corresponding Acquiring Fund Sub-Account;

(iii) any transaction that includes an allocation to one of the Acquired Fund Sub-Accounts will automatically be allocated to the corresponding Acquiring Fund Sub-Account;

(iv) unless you direct us otherwise, if you are enrolled in any administrative program that includes transfers of Contract Value or allocation to one of the Acquired Fund Sub-Accounts (i.e., DCA, DCA Plus, InvestEase®, Asset Rebalancing Program or other program trades), your enrollment will automatically be updated to reflect the corresponding Acquiring Fund Sub-Account;

(v) If you are currently invested in one of the investment models that includes one of the Acquired Fund Sub-Accounts, the model will be automatically updated to reflect the corresponding Acquiring Fund Sub-Account. The percentage allocation of the Acquired Fund Sub-Account will also be moved to the total allocation of the Acquiring Fund Sub-Account. For example, if your model allocated 5% to one of the Acquired Fund Sub-Accounts, that 5% will now be allocated to the corresponding Acquiring Fund Sub-Account. If you are in a “self-select” model and would like to change your selections or invest in a different model, you may provide us with new instructions at any time.

(vi) all references and information contained in the prospectus for your Contract related to any of the Acquired Funds are deleted and replaced with the corresponding Acquiring Fund.
