We were notified of a problem with our affiliated portfolios’ accounting agent’s system on Monday, August 24, 2015. Due to a system problem, the values of the units for certain Subaccounts may reflect pricing and holdings as of a prior date and/or may not have been reported accurately. Once the accurate unit prices of the Subaccounts are determined, we will correct all account values and transactions, as needed, to reflect the correct unit values. This system failure did not affect the unaffiliated portfolios in this Annuity.

PLEASE RETAIN THIS SUPPLEMENT WITH YOUR PROSPECTUS
