  7790-PTB 2  2) The following language is added to the CONTRACT OPTION PROVISIONS of the Contract.    "Index-linked returns do not include the portion of returns generated by the underlying Index that  come from dividends. The Index Adjustment Factors used in determining the Index Adjustment  are not guaranteed and can be changed by the Company on any Index Account Option Term  Anniversary, subject to the guarantees in the Supplemental Contract Data pages. Any such  changes can affect the Index Adjustment.    The Index Adjustment is determined as follows:    Performance Trigger with Buffer    Index Adjustment = IF Pe– Pb >= 0, THEN = IAOV x PTR,  IF Pe– Pb < 0, THEN = IAOV x MINIMUM [(Pe– Pb) / Pb + B, 0]    During the Index Account Option term:     The Index Account Option value will be equal to the Interim Value. The Index Adjustment to the  Interim Value will be calculated according to the preceding formula using the following  definitions:    Pb = the Index price at the beginning of the Index Account Option term.   Pe = the Index price on the date the Interim Value is calculated.   IAOV = the greater of the Index Account Option value at the beginning of the Index  Account Option term, reduced for any gross partial withdrawals in the same  proportion that the Interim Value was reduced on the date of the withdrawal, or  zero.   PTR =        ×   × the PTR declared at the beginning of the Index   Account Option term.   B =        ×   × the Buffer declared at the beginning of the Index   Account Option term.     The Index Adjustment will be calculated by the Company based on the closing price of the Index  on the date the Interim Value is calculated.
