The value of an individual issuer&amp;#146;s securities can be more volatile than the market as a whole and can perform differently than the market as a whole. &amp;nbsp;Debt obligations rated within the lowest of the four highest debt rating categories have speculative characteristics and changes in economic conditions or other circumstances are more likely to lead to a weaker capacity of the issuer to make principal and interest payments than would be the case with higher rated securities. &amp;nbsp;If after acquisition by the Portfolio, a change in the credit quality of a debt security causes the security to fall below investment grade, the investment adviser will consider selling the security if the sale will not have an adverse effect on the Portfolio.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Credit Risk&lt;/i&gt;. &amp;nbsp;If the issuer of a debt security fails to pay interest or principal in a timely manner, the Portfolio&amp;#146;s return will be lower.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;U.S. Government Agency Securities&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio invests in securities that are issued or guaranteed by the U.S. Treasury or by an agency or instrumentality of the U.S. Government, including the Government National Mortgage Association (&amp;#147;Ginnie Mae&amp;#148;), the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), the Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;), the Federal Home Loan Banks (&amp;#147;FHLBs&amp;#148;) and the Federal Farm Credit Bank (&amp;#147;FFCB&amp;#148;). &amp;nbsp;U.S. Government securities may be backed by the full faith and credit of the U.S. Treasury, the right to borrow from the U.S. Treasury, or the credit of the agency or instrumentality issuing or guaranteeing the security. Securities issued by Ginnie Mae are supported by the full faith and credit of the U.S. Treasury. Obligations of the FHLBs, FFCB, Fannie Mae and Freddie Mac are backed by the credit of the agency or instrumentality issuing the obligation. &amp;nbsp;In September 2008, the U.S. Treasury placed Fannie Mae and Freddie Mac under conservatorship and appointed the Federal Housing Finance Agency to manage their daily operations. &amp;nbsp;The U.S. Government may not provide support for obligations of its agencies or instrumentalities if not obligated by law to do so.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Mortgage-Backed Securities&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio invests in securities that are issued or guaranteed by Ginnie Mae, Fannie Mae and Freddie Mac that are backed by pools of mortgage loans. Mortgage-backed securities are based upon different types of mortgage loans, and may include &amp;#147;sub-prime,&amp;#148; &amp;#147;alt-A&amp;#148; or other types of loans that carry greater repayment risks. &amp;nbsp;Since mortgage-backed securities issued by Ginnie Mae, Fannie Mae and Freddie Mac are not registered under the Securities Act of 1933, information about such securities may not be as readily available as for registered securities. &amp;nbsp;Only those mortgage-backed securities that are issued by Ginnie Mae are backed by the full faith and credit of the U.S. Treasury. &amp;nbsp;During periods of declining interest rates, prepayment of the mortgages underlying the securities can be expected to accelerate, shortening the estimated average life of the security, while increasing interest rates could extend the estimated average life of the securities. &amp;nbsp;Because of the unpredictable payment characteristics, it is often not possible to predict accurately the average life or realized yield of a particular issue. &amp;nbsp;If the Portfolio purchases a mortgage-backed security at a premium, it may experience a loss if there is a decline in the market value of the security, whether resulting from changes in interest rates or prepayments of the underlying mortgage loans.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Credit Quality&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio may invest up to 20% of its assets in debt obligations rated in one of the top four rating categories by nationally recognized rating organizations such as Moody&amp;#146;s or Standard &amp;#38; Poor&amp;#146;s. &amp;nbsp;Credit ratings evaluate the expectation that scheduled interest and principal payments will be made in a timely manner. &amp;nbsp;They do not reflect any judgment of market risk and are not a recommendation to purchase, sell or hold securities. &amp;nbsp;Conflicts of interest can arise in the securities rating process since issuers or underwriters make payments to the rating agencies to determine the credit ratings for securities they issue or underwrite. &amp;nbsp;Downgrades in ratings of securities held by the Government Securities Portfolio may adversely affect the price of those securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Income Risk&lt;/i&gt;. &amp;nbsp;Falling interest rates will cause the Portfolio&amp;#146;s income to decline.&lt;/li&gt;&lt;/ul&gt;When you sell shares of the Portfolio, they could be worth less than what you paid for them. &amp;nbsp;An investment in the Portfolio is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</rr:RiskNarrativeTextBlock>

&amp;nbsp;If during periods of falling interest rates an issuer of a debt security held by the Portfolio repays a higher yielding bond before its maturity date, the Portfolio will reinvest these unanticipated proceeds at lower rates. &amp;nbsp;As a result the Portfolio would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Issuer-Specific Risk.&lt;/i&gt; &amp;nbsp;&amp;nbsp;The value of an individual issuer&amp;#146;s securities can be more volatile than the market as a whole and can perform differently than the market as a whole. &amp;nbsp;Debt obligations rated within the lowest of the four highest debt rating categories have speculative characteristics and changes in economic conditions or other circumstances are more likely to lead to a weaker capacity of the issuer to make principal and interest payments than would be the case with higher rated securities. &amp;nbsp;If after acquisition by the Portfolio, a change in the credit quality of a debt security causes the security to fall below investment grade, the investment adviser will consider selling the security if the sale will not have an adverse effect on the Portfolio.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Credit Risk.&lt;/i&gt; &amp;nbsp;If the issuer of a debt security fails to pay interest or principal in a timely manner, the Portfolio&amp;#146;s return will be lower.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;U.S. Government Agency Securities&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio invests in securities that are issued or guaranteed by the U.S. Treasury or by an agency or instrumentality of the U.S. Government, including the Government National Mortgage Association (&amp;#147;Ginnie Mae&amp;#148;), the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), the Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;), the Federal Home Loan Banks (&amp;#147;FHLBs&amp;#148;) and the Federal Farm Credit Bank (&amp;#147;FFCB&amp;#148;). &amp;nbsp;U.S. Government securities may be backed by the full faith and credit of the U.S. Treasury, the right to borrow from the U.S. Treasury, or the agency or instrumentality issuing or guaranteeing the security. &amp;nbsp;Securities issued by Ginnie Mae are supported by the full faith and credit of the U.S. Treasury. &amp;nbsp;Obligations of the FHLBs, FFCB, Fannie Mae and Freddie Mac are backed by the credit of the agency or instrumentality issuing the obligation. &amp;nbsp;In September 2008, the U.S. Treasury placed Fannie Mae and Freddie Mac under conservatorship and appointed the Federal Housing Finance Agency to manage their daily operations. &amp;nbsp;The U.S. Government may not provide support for obligations of its agencies or instrumentalities if not obligated by law to do so.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Mortgage-Backed Securities&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio invests in securities that are issued or guaranteed by Ginnie Mae, Fannie Mae and Freddie Mac that are backed by pools of mortgage loans. &amp;nbsp;Mortgage-backed securities are based upon different types of mortgage loans, and may include &amp;#147;sub-prime,&amp;#148; &amp;#147;alt-A&amp;#148; or other types of loans that carry greater repayment risks. &amp;nbsp;Since mortgage-backed securities issued by Ginnie Mae, Fannie Mae and Freddie Mac are not registered under the Securities Act of 1933, information about such securities may not be as readily available as for registered securities. &amp;nbsp;Only those mortgage-backed securities that are issued by Ginnie Mae are backed by the full faith and credit of the U.S. Treasury. &amp;nbsp;During periods of declining interest rates, prepayment of the mortgages underlying the securities can be expected to accelerate, shortening the estimated average life of the security, while increasing interest rates could extend the estimated average life of the securities. &amp;nbsp;Because of the unpredictable payment characteristics, it is often not possible to predict accurately the average life or realized yield of a particular issue. &amp;nbsp;If the Portfolio purchases a mortgage-backed security at a premium, it may experience a loss if there is a decline in the market value of the security, whether resulting from changes in interest rates or prepayments of the underlying mortgage loans.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Credit Quality&lt;/i&gt;. &amp;nbsp;The Government Securities Portfolio may invest up to 20% of its assets in debt obligations rated in one of the top four rating categories by nationally recognized rating organizations such as Moody&amp;#146;s or Standard &amp;#38; Poor&amp;#146;s. &amp;nbsp;Credit ratings evaluate the expectation that scheduled interest and principal payments will be made in a timely manner. &amp;nbsp;They do not reflect any judgment of market risk and are not a recommendation to purchase, sell or hold securities. &amp;nbsp;Conflicts of interest can arise in the securities rating process since issuers or underwriters make payments to the rating agencies to determine the credit ratings for securities they issue or underwrite. &amp;nbsp;Downgrades in ratings of securities held by the Government Securities Portfolio may adversely affect the price of those securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;i&gt;Income Risk.&lt;/i&gt; &amp;nbsp;Falling interest rates will cause the Portfolio&amp;#146;s income to decline.&lt;/li&gt;&lt;/ul&gt;When you sell shares of the Portfolio, they could be worth less than what you paid for them. &amp;nbsp;An investment in the Portfolio is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</rr:RiskNarrativeTextBlock>
