with the cost of investing in other mutual funds. The Example does not include any separate account or 
policy fees or charges imposed under the variable annuity policies and variable universal life insurance 
policies for which the Portfolio is an investment option. If they were included, your costs would be 
higher. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated whether 
or not you redeem all of your shares at the end of those periods. The Example also assumes that your 
investment has a 5% return each year and that the Portfolio's operating expenses remain the same. The 
Example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, 
for the current duration of the arrangement only. Although your actual costs may be higher or lower,

be subject to the risks associated with securities issued by companies of the applicable market capitalization.&#160; 
Securities of small-cap and mid-cap companies may be subject to greater price volatility, significantly 
lower trading volumes, cyclical, static or moderate growth prospects and greater spreads between their 
bid and ask prices than securities of larger companies. Smaller capitalization companies frequently rely 
on narrower product lines and niche markets and may be more vulnerable to adverse business or market 
developments.&#160; Securities issued by larger companies may have less growth potential and may not be able 
to attain the high growth rates of successful smaller companies, especially during strong economic periods.&#160; 
In addition, larger companies may be less capable of responding quickly to competitive challenges and 
industry changes, including those resulting from improvements in technology, and may suffer sharper price 
declines as a result of earnings disappointments.&#160; There is a risk that the securities issued by companies 
of a certain market capitalization may underperform the broader market at any given time.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Securities Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; An issuer of a security is considered to be a U.S. or foreign issuer based on 
the issuer&#x2019;s &#x201c;country of risk&#x201d; (or similar designation) as determined by a third party such as 
Bloomberg (or another similar third party). The issuer&#x2019;s &#x201c;country of risk&#x201d; is determined based 
on a number of criteria, which may change from time to time and currently include, but are not limited 
to, its country of domicile, the primary stock exchange on which it trades, the location from which the 
majority of its revenue comes, and its reporting currency. Although a Portfolio will generally rely on 
an issuer&#x2019;s &#x201c;country of risk&#x201d; (or similar designation) as determined by Bloomberg (or another similar 
third party) when categorizing securities as either U.S. or foreign-based, it is not required to do so. 
&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;Investments in foreign (non-U.S.) securities may be riskier than investments in 
U.S. securities. Foreign regulatory regimes and securities markets can have less stringent investor protections 
and disclosure standards and less liquid trading markets than U.S. regulatory regimes and securities 
markets, and can experience political, social and economic developments that may affect the value of 
investments in foreign securities. Foreign securities may also subject the Portfolio's investments to 
changes in currency rates. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. Economic sanctions 
may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and thus may make the Portfolio&#x2019;s investments in such securities less 
liquid or more difficult to value. Such sanctions may also cause a decline in the value of securities 
issued by the sanctioned country or companies located in or economically &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;tied to the sanctioned country. In addition, as a result of economic sanctions 
and other similar governmental actions or developments, the Portfolio may be forced to sell or otherwise 
dispose of foreign investments at inopportune times or prices. The Portfolio may seek to hedge against 
its exposure to changes in the value of foreign currency, but there is no guarantee that such hedging 
techniques will be successful in reducing any related foreign currency valuation risk. &lt;/p&gt;</rr:RiskTextBlock>

If growth companies do not increase their earnings at a rate expected by investors, the market price 
of the stock may decline significantly, even if earnings show an absolute increase. Growth company stocks

To the extent the Portfolio focuses its investments in particular sectors of the economy, the Portfolio&#x2019;s 
performance may be more subject to the risks of volatile economic cycles and/or conditions or developments 
adversely affecting such sectors than if the Portfolio held a broader range of investments. Individual 
sectors may fluctuate more widely than the broader market. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;Companies in the same 
economic sector may be similarly affected by economic, regulatory, political or market events or conditions, 
which may make the Portfolio more vulnerable to unfavorable developments in that economic sector than 
funds that invest more broadly. Generally, the more broadly the Portfolio invests, the more it spreads 
risk and potentially reduces the risks of loss and volatility.&lt;/p&gt;</rr:RiskTextBlock>

at the time of purchase and subsequently become illiquid due to, among other things, events relating 
to the issuer of the securities, market events, operational issues, economic conditions, investor perceptions 
or lack of market participants. The lack of an active trading market may make it difficult to sell or 
obtain an accurate price for a security. If market conditions or issuer specific developments make it 
difficult to value securities, the Portfolio may value these securities using more subjective methods, 
such as fair value pricing. In such cases, the value determined for a security could be different than 
the value realized upon such security's sale. As a result, an investor could pay more than the market 
value when buying shares or receive less than the market value when selling shares. This could affect 
the proceeds of any redemption or the number of shares an investor receives upon purchase. The Portfolio 
is subject to the risk that it could not meet redemption requests within the allowable time period without 
significant dilution of remaining investors' interests in the Portfolio. To meet redemption requests 
or to raise cash to pursue other investment opportunities, the Portfolio may be forced to sell securities 
at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Portfolio&#x2019;s

Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing 
in other mutual funds. The Example does not include any separate account or policy fees or charges imposed 
under the variable annuity policies and variable universal life insurance policies for which the Portfolio 
is an investment option. If they were included, your costs would be higher. The Example assumes that 
you invest $10,000 in the Portfolio for the time periods indicated whether or not you redeem all of your 
shares at the end of those periods. The Example also assumes that your investment has a 5% return each 
year and that the Portfolio's operating expenses remain the same. The Example reflects the contractual 
fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement 
only. Although your actual costs may be higher or lower, based on these assumptions your costs would

to be a U.S. or foreign issuer based on the issuer&#x2019;s &#x201c;country of risk&#x201d; (or similar designation) 
as determined by a third party such as Bloomberg (or another similar third party). The issuer&#x2019;s &#x201c;country 
of risk&#x201d; is determined based on a number of criteria, which may change from time to time and currently 
include, but are not limited to, its country of domicile, the primary stock exchange on which it trades, 
the location from which the majority of its revenue comes, and its reporting currency. Although a Portfolio 
will generally rely on an issuer&#x2019;s &#x201c;country of risk&#x201d; (or similar designation) as determined by 
Bloomberg (or another similar third party) when categorizing securities as either U.S. or foreign-based,

U.S. securities. Foreign regulatory regimes and securities markets can have less stringent investor protections 
and disclosure standards and less liquid trading markets than U.S. regulatory regimes and securities 
markets, and can experience political, social and economic developments that may affect the value of 
investments in foreign securities. Foreign securities may also subject the Portfolio's investments to 
changes in currency rates. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. Economic sanctions 
may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and thus may make the Portfolio&#x2019;s investments in such securities less 
liquid or more difficult to value. Such sanctions may also cause a decline in the value of securities 
issued by the sanctioned country or companies located in or economically tied to the sanctioned country. 
In addition, as a result of economic sanctions and other similar governmental actions or developments, 
the Portfolio may be forced to sell or otherwise dispose of foreign investments at inopportune times 
or prices. The Portfolio may seek to hedge against its exposure to changes in the value of foreign currency, 
but there is no guarantee that such hedging techniques will be successful in reducing any related foreign 
currency valuation risk. &lt;/p&gt;</rr:RiskTextBlock>

at the time of purchase and subsequently become illiquid due to, among other things, events relating 
to the issuer of the securities, market events, operational issues, economic conditions, investor perceptions 
or lack of market participants. The lack of an active trading market may make it difficult to sell or 
obtain an accurate price for a security. If market conditions or issuer specific developments make it 
difficult to value securities, the Portfolio may value these securities using more subjective methods, 
such as fair value pricing. In such cases, the value determined for a security could be different than 
the value realized upon such security's sale. As a result, an investor could pay more than the market 
value when buying shares or receive less than the market value when selling shares. This could affect 
the proceeds of any redemption or the number of shares an investor receives upon purchase. The Portfolio 
is subject to the risk that it could not meet redemption requests within the allowable time period without 
significant dilution of remaining investors' interests in the Portfolio. To meet redemption requests 
or to raise cash to pursue other investment opportunities, the Portfolio may be forced to sell securities 
at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Portfolio&#x2019;s

it believes can generate profits over time. The Subadvisor identifies companies with the potential for

growth, product or market cycles and/or favorable valuations.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio also may 
invest in U.S. dollar-denominated American Depositary Receipts (&#x201c;ADRs&#x201d;). ADRs typically are issued 
by U.S. banks or trust companies and represent indirect ownership interests in securities of non-U.S. 
issuers that are publicly traded in overseas markets. ADRs are traded in the United States on national 
securities exchanges and in the over-the-counter market, and may be converted into the underlying foreign 
securities. The Portfolio may purchase ADRs through "sponsored" or "unsponsored" facilities. A sponsored 
facility is established jointly by the issuer of the underlying security and a depositary. A depositary 
may establish an unsponsored facility without participation by the issuer of the underlying security. 
To the extent such ADRs have similar economic characteristics to stocks of companies as described in 
the Portfolio's policy with respect to the investment of at least 80% of its net assets, the market value 
of such ADRs will be included in the 80% calculation.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio typically 
sells a stock when the Subadvisor believes there is a more attractive alternative, or there are deteriorating 
fundamentals, such as a loss of competitive advantage, a failure in management execution or deteriorating 
capital structure. The Portfolio may sell stocks when the Subadvisor&#x2019;s evaluation of a sector has changed.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

companies may have limited product lines, markets or financial resources, or may depend on a limited 
management group.  In addition, these companies are strongly affected by worldwide technological developments, 
and their products and services may not be economically successful or may quickly become outdated. Investor 
perception may play a greater role in determining the day-to-day value of tech stocks than it does in 
other sectors.  Investments made in anticipation of future products and services may decline dramatically 
in value if the anticipated products or services are delayed or cancelled. The risks associated with 
technology companies are magnified in the case of small-cap technology companies. The shares of smaller 
technology companies tend to trade less frequently than those of larger, more established companies, 
which can have an adverse effect on the pricing of these securities and on the &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Portfolio&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;'s

investments in particular sectors of the economy, the Portfolio&#x2019;s performance may be more subject to 
the risks of volatile economic cycles and/or conditions or developments adversely affecting such sectors 
than if the Portfolio held a broader range of investments. Individual sectors may fluctuate more widely 
than the broader market. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;Companies in the same economic sector may 
be similarly affected by economic, regulatory, political or market events or conditions, which may make 
the Portfolio more vulnerable to unfavorable developments in that economic sector than funds that invest 
more broadly. Generally, the more broadly the Portfolio invests, the more it spreads risk and potentially 
reduces the risks of loss and volatility. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may be more susceptible to

may have less growth potential and may not be able to attain the high growth rates of successful smaller

of responding quickly to competitive challenges and industry changes, including those resulting from 
improvements in technology, and may suffer sharper price declines as a result of earnings disappointments.&#160;

security is considered to be a U.S. or foreign issuer based on the issuer&#x2019;s &#x201c;country of risk&#x201d; (or 
similar designation) as determined by a third party such as Bloomberg (or another similar third party). 
The issuer&#x2019;s &#x201c;country of risk&#x201d; is determined based on a number of criteria, which may change from 
time to time and currently include, but are not limited to, its country of domicile, the primary stock 
exchange on which it trades, the location from which the majority of its revenue comes, and its reporting 
currency. Although a Portfolio will generally rely on an issuer&#x2019;s &#x201c;country of risk&#x201d; (or similar 
designation) as determined by Bloomberg (or another similar third party) when categorizing securities 
as either U.S. or foreign-based, it is not required to do so. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; text-align:left; font-weight:normal; text-decoration:none;"&gt;Investments 
in foreign (non-U.S.) securities may be riskier than investments in U.S. securities. Foreign regulatory 
regimes and securities markets can have less stringent investor protections and disclosure standards 
and less liquid trading markets than U.S. regulatory regimes and securities markets, and can experience 
political, social and economic developments that may affect the value of investments in foreign securities. 
Foreign securities may also subject the Portfolio's investments to changes in currency rates. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. Economic sanctions may be, and have been, imposed 
against certain countries, organizations, companies, entities and/or individuals. Economic sanctions 
and other similar governmental actions or developments could, among other things, effectively restrict 
or eliminate the Portfolio&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign 
securities, and thus may make the Portfolio&#x2019;s investments in such securities less liquid or more difficult 
to value. Such sanctions may also cause a decline in the value of securities issued by the sanctioned 
country or companies located in or economically tied to the sanctioned country. In addition, as a result 
of economic sanctions and other similar governmental actions or developments, the Portfolio may be forced 
to sell or otherwise dispose of foreign investments at inopportune times or prices. The Portfolio may 
seek to hedge against its exposure to changes in the value of foreign currency, but there is no guarantee 
that such hedging techniques will be successful in reducing any related foreign currency valuation risk.

respect to securities of companies that conduct their business activities in emerging markets or whose

recordkeeping, financial reporting and other requirements, which limit the quality and availability of 
financial information; (iii) the absence of developed legal systems, including structures governing private

The Portfolio&#x2019;s investments may be illiquid at the time of purchase or liquid at the time of purchase 
and subsequently become illiquid due to, among other things, events relating to the issuer of the securities, 
market events, operational issues, economic conditions, investor perceptions or lack of market participants. 
The lack of an active trading market may make it difficult to sell or obtain an accurate price for a 
security. If market conditions or issuer specific developments make it difficult to value securities, 
the Portfolio may value these securities using more subjective methods, such as fair value pricing. In 
such cases, the value determined for a security could be different than the value realized upon such 
security's sale. As a result, an investor could pay more than the market value when buying shares or 
receive less than the market value when selling shares. This could affect the proceeds of any redemption 
or the number of shares an investor receives upon purchase. The Portfolio is subject to the risk that 
it could not meet redemption requests within the allowable time period without significant dilution of 
remaining investors' interests in the Portfolio. To meet redemption requests or to raise cash to pursue 
other investment opportunities, the Portfolio may be forced to sell securities at an unfavorable time 
and/or under unfavorable conditions, which may adversely affect the Portfolio&#x2019;s performance. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>
