fund seeks to achieve its investment objective by normally investing in a combination of common stocks 
and other equity securities, debt securities and convertible securities. It is expected that substantially 
all of the fund&#x2019;s debt securities and a substantial portion of its convertible securities will consist 
of securities rated below investment grade (sometimes referred to as &#x201c;high yield securities&#x201d; or &#x201c;junk 
bonds&#x201d;). The allocation of the fund&#x2019;s investments across these asset classes will vary from time 
to time, but as of the date of this prospectus, the fund expects its assets to be allocated approximately 
evenly to the following three strategies: &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:bold; text-decoration:none;"&gt;U.S. Growth Equities: &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;This strategy&#x2019;s subadviser invests the fund&#x2019;s assets primarily in equity securities 
of U.S. companies with market capitalizations of at least $1 billion. The portfolio managers attempt 
to include securities in the fund&#x2019;s portfolio that exhibit the greatest combination of earnings growth 
potential, quality (as reflected by consistent business fundamentals), and attractive valuation. This 
strategy may also include non-U.S. securities, including through American Depositary Receipts (ADRs), 
as well as securities issued in initial public offerings (IPOs) and real estate investment trusts (REITs).&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;Under 
normal circumstances, this strategy&#x2019;s subadviser expects to employ a strategy of writing (selling) 
options on stocks and/or indexes related to the fund&#x2019;s equity portfolio. The extent of the fund&#x2019;s 
use of this strategy will vary depending on market conditions and other factors, and the fund may from 
time to time write options on only a portion, or none, of the fund&#x2019;s equity portfolio. This strategy&#x2019;s 
subadviser may also seek to generate additional income for the fund by buying equity-linked notes (ELNs) 
that are designed by this strategy&#x2019;s subadviser to have the effect of writing (selling) options on 
a portion of its equity portfolio.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:bold; text-decoration:none;"&gt;Convertible Securities: &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;This strategy&#x2019;s subadviser follows a disciplined, fundamental bottom-up research 
process, which facilitates the early identification of issuers demonstrating the ability to improve their 
fundamental characteristics. The portfolio managers use fundamental analysis and qualitative measures 
to assess and select issuers they believe exhibit high visibility of future expected operating performance. 
The fundamental research process generally includes: a breakdown of a company and its growth by division 
and region, including revenue model analysis; profit margin analysis; analysis of experience and quality 
of its management; industry dynamics and competitive analysis; distribution channel and supply chain 
analysis; and macroeconomic climate analysis. Also, the portfolio managers typically look for the following 
in candidates: the potential for bond rating upgrades; debt reduction capabilities; the ability to secure 
other sources of capital; the potential to be recognized as an acquisition candidate; and corporate dividend 
policy. The subadvisers may consider selling a particular security when the portfolio managers perceive 
a change in company fundamentals; a decline in relative attractiveness to other issues; and/or a decline 
in industry fundamentals, or if any of the original reasons for purchase materially changes. The convertible 
securities in which the fund may invest include bonds, debentures, notes, preferred stocks, &#x201c;synthetic&#x201d; 
convertibles and other securities or investments that may be converted or exchanged (by the holder or 
by the issuer) into equity securities of the issuer (or cash or securities of equivalent value). The 
weighted average maturity of the portion of the fund&#x2019;s assets invested in convertible and debt securities 
will typically be 10 years or less, although the weighted average maturity may vary depending on market 
and other conditions.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;With respect to convertible securities, the portfolio managers 
evaluate each such security&#x2019;s investment characteristics as a fixed income instrument as well as its 
potential for capital appreciation. Under normal market conditions, the portfolio managers seek to invest 
in securities that can participate in the upside of the underlying equity and provide downside protection 
from the bond.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:bold; text-decoration:none;"&gt;High-Income Credits: &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; color:#000000; font-weight:normal; text-decoration:none;"&gt;Under 
normal circumstances, this strategy invests in various types of lower-rated, higher yielding debt instruments, 
including corporate obligations, first- and second- lien senior floating rate loans and other debt obligations. 
In selecting investments for purchase and sale, the subadviser will emphasize instruments which are within 
the segment of the high yield market it has targeted, which are loans and instruments rated below investment 
grade (sometimes referred to as &#x201c;high yield securities&#x201d; or &#x201c;junk bonds&#x201d;) or unrated instruments 
that the subadviser believes are of comparable quality. The fund&#x2019;s loan investments will include both 
secured loans and &#x201c;covenant lite&#x201d; loans which have few or no financial maintenance covenants that 
would require a borrower to maintain certain financial metrics. In addition, to implement this investment 
strategy, the fund may buy or sell derivative instruments (such as swaps, including credit default swaps, 
futures and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets 
and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit 
risks. The fund may invest in debt obligations of U.S. and non-U.S. issuers, including emerging market 
debt. It is expected that a high percentage of the fund&#x2019;s investments in this strategy will be rated 
below investment grade. The fund&#x2019;s fixed income portfolio will be managed with a duration that is close 
to the fund&#x2019;s comparative benchmark, the ICE BofA US High Yield BB-B Constrained Index, which is generally 
between 3 and 6 years. Duration measures a bond or fund&#x2019;s sensitivity to interest rate or other changes 
(such as changes in a bond&#x2019;s yield) and is &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;expressed as a number of years. The higher the number, the greater the risk. Under 
normal circumstances, for example, if a portfolio has a duration of five years, its value will change 
by 5% if yields change by 1%. Shorter duration bonds generally result in lower expected volatility. The 
fund may also invest a portion of its assets in instruments that are restricted as to resale. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:11.0pt; font-family:Sans-Serif; text-align:left; color:#000000; font-weight:normal; text-decoration:none;"&gt;The &#x201c;Principal Risks&#x201d; section in the summary prospectus and the summary section

the overall economy, specific industries or companies in which the fund invests can be worse than expected, 
and investments may fail to perform as the subadvisers expect. As a result, the value of your shares 
may decrease. Purchase and redemption activities by fund shareholders may impact the management of the

ELNs, it receives cash but limits its opportunity to profit from an increase in the market value of the 
reference benchmark because of the limits relating to the call options written within the particular 
ELN. Investments in ELNs often have risks similar to the reference benchmark, which include market risk. 
Should the price of the reference benchmark move in an unexpected manner, the fund may not achieve the 
anticipated benefits of an investment in an ELN, and may realize losses, which could be significant and 
could include the fund&#x2019;s entire principal investment.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>
