The “Selection of the Annuity Commencement Date” section is hereby deleted and replaced with the following:

You select the Annuity Commencement Date in your Application. The following restrictions apply to the date you may select:

l	The earliest possible Annuity Commencement Date is the first day of the second month following your Contract Date.
l	The latest possible Annuity Commencement Date is the first day of the month following the Annuitant’s 95th birthday (“maximum Annuity Commencement Date”) or, if there is a Co-Annuitant, the 95th birthday of the younger of the Annuitant and Co-Annuitant.
l	The Annuity Commencement Date must always be the first day of a calendar month.

You may change the Annuity Commencement Date from time to time by sending us written notice, in a form acceptable to us, with the following additional limitations:

l	We must receive your notice, in good order, at least 30 days before the current Annuity Commencement Date.
l	The new Annuity Commencement Date must be at least 30 days after we receive the notice.

There may be other restrictions on your selection of the Annuity Commencement Date imposed by your retirement plan or applicable law. In most situations, current law requires that for a Qualified Contract, certain minimum distributions must commence no later than April 1 following the year the Annuitant reaches age 70½ (or, for Qualified Contracts other than IRAs, no later than April 1 following the year the Annuitant retires, if later than the year the Annuitant reaches age 70½).

THIS SUPPLEMENT SHOULD BE READ AND RETAINED FOR FUTURE REFERENCE.
