*The Portfolio's returns are after deduction of expenses and
do not include Contract charges. If Contract charges were
included, the annual returns would have been lower than
those shown. During certain periods shown, fee waivers
and/or expense reimbursements may be in effect. Without such
fee waivers and/or expense reimbursements, the returns for
the Portfolio would have been lower.
**Returns of Portfolios in existence for less than one year
are not annualized. Portfolio (Class I) inception: 5/1/88.
Portfolio (Class II) inception: 4/28/05.
***The Standard   & Poor's 500 Composite Stock Price Index
(S&P 500 Index)-an unmanaged index of 500 stocks of large
U.S. companies-gives a broad look at how stock prices have
performed.   These returns do not include the effect of any
investment management expenses.    These returns would have
been lower if they included the effect of these expenses.
The "Since Inception" return reflects the closest calendar
month end return to the inception date of the Portfolio's
Class II shares.
****The Lipper Natural Resources Fund Index is an unmanaged,
equally-weighted index of the largest mutual funds in the
Lipper Natural Resources category of funds. These returns do
not include the effect of any investment management
expenses.    These returns would have been lower if they
included the effect of these expenses. The "Since Inception"
return reflects the closest calendar month end return to the
inception date of the Portfolio's Class II shares.
*****The Lipper Average is calculated by Lipper Analytical
Services,   Inc. and reflects the return of certain
portfolios underlying variable life and annuity products.
The returns are net of investment fees and fund expenses but
not product charges.   These returns would have been lower
if they included the effect of product charges. The "Since
Inception" return reflects the closest calendar month end
return to the inception date of the Portfolio's Class II
shares.
