A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations except for those debt obligations that are privately rated. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the credit worthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change. &lt;/div&gt;</oef:HoldingsTableTextBlock>

A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations except for those debt obligations that are privately rated. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the credit worthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.</oef:CreditQualityExplanationTextBlock>

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. A credit rating is an assessment provided by a NRSRO of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under &#x201c;Government &amp;amp; Agency.&#x201d; Credit ratings are subject to change.&lt;/div&gt;

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. A credit rating is an assessment provided by a NRSRO of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under &#x201c;Government &amp;amp; Agency.&#x201d; Credit ratings are subject to change.</oef:CreditQualityExplanationTextBlock>

A credit rating is an assessment provided by a NRSRO, of the creditworthiness of an issuer with respect to debt obligations.

Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under &#x201c;Government &amp;amp; Agency.&#x201d; Credit ratings are subject to change.&lt;/div&gt;

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. Ratings are measured highest to lowest on a scale that generally ranges from AAA to D for long-term ratings and A-1+ to C for short-term ratings. Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher or a short-term credit rating of A-3 or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Treasury, U.S. Agency and U.S. Agency mortgage-backed securities appear under &#x201c;Government &amp;amp; Agency&#x201d;. Credit ratings are subject to change. &lt;/div&gt;</oef:HoldingsTableTextBlock>

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. Ratings are measured highest to lowest on a scale that generally ranges from AAA to D for long-term ratings and A-1+ to C for short-term ratings. Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher or a short-term credit rating of A-3 or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Treasury, U.S. Agency and U.S. Agency mortgage-backed securities appear under &#x201c;Government &amp;amp; Agency&#x201d;. Credit ratings are subject to change.</oef:CreditQualityExplanationTextBlock>

A credit rating is an assessment provided by a NRSRO of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under &#x201c;Government &amp;amp; Agency.&#x201d; Credit ratings are subject to change.&lt;/div&gt;

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. A credit rating is an assessment provided by a NRSRO of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under &#x201c;Government &amp; Agency.&#x201d; Credit ratings are subject to change.</link:footnote>

For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. Ratings are measured highest to lowest on a scale that generally ranges from AAA to D for long-term ratings and A-1+ to C for short-term ratings. Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher or a short-term credit rating of A-3 or higher. &#x201c;NR&#x201d; indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Treasury, U.S. Agency and U.S. Agency mortgage-backed securities appear under &#x201c;Government &amp; Agency&#x201d;. Credit ratings are subject to change.</link:footnote>
