IMPORTANT INFORMATION REGARDING AN UPCOMING FUND REORGANIZATION
1.    The Board of Trustees of ING Investors Trust and ING Variable Funds have approved a proposal
to reorganize a certain fund. Subject to shareholder approval, effective after the close of
business on or about December 2, 2011, (the “Reorganization Date”) the following Disappearing
Portfolio will reorganize into and become part of the following Surviving Portfolio:
Disappearing Portfolio			Surviving Portfolio
ING Core Growth and Income Portfolio (Class S)			ING Growth and Income Portfolio (Class S)
IMPORTANT INFORMATION ABOUT THE UPCOMING FUND REORGANIZATION
·	Prior to the Reorganization Date, you may transfer amounts allocated to a subaccount that
	invests in a Disappearing Portfolio to any other available subaccount or any available fixed
	interest option. See also the Transfers section of your Contract Prospectus or the
	Investment Options section of your Contract Prospectus Summary for further
	information about making transfers, including limits on transfers.
·	On the Reorganization Date, your investment in a subaccount that invests in a Disappearing
	Portfolio will automatically become an investment in the subaccount that invests in the
	corresponding Surviving Portfolio with an equal total net asset value.
·	You will not incur any fees or charges or any tax liability because of the reorganization.
·	Unless you provide us with alternative allocation instructions, all future allocations directed to
	the subaccount that invests in the Disappearing Portfolio after the Reorganization Date will be
	automatically allocated to the subaccount that invests in the corresponding Surviving Portfolio.
	You may give us alternative allocation instructions at any time by contacting our Customer

·	After the Reorganization Date, the Disappearing Portfolio will no longer exist and all
	references to it in the Contract Prospectus and Contract Prospectus Summary will be replaced
	by the corresponding Surviving Portfolio.
·	The ING Growth and Income Portfolio (Class S) is available only to those contracts that were
	offering the ING Growth and Income Portfolio II (Class S) as of August 7, 2009 or to contracts
	that were offering ING Core Growth and Income Portfolio (Class S) as of December 2, 2011.
2.    The minimum and maximum Total Annual Fund Operating Expenses shown in the Contract
Prospectus will not change as a result of the reorganization. Therefore, there will be no change to the
