In assigning a credit rating to a security, the fund looks specifically to the ratings assigned to the issuer of the security by Standard &amp;amp; Poor&#x2019;s, Moody&#x2019;s and/or Fitch. If agency ratings differ, the security will be considered to have received the highest of those ratings, consistent with the fund&#x2019;s investment policies. Securities in the &#x201c;unrated&#x201c; category (above) have not been rated by a rating agency; however, the investment adviser performs its own credit analysis and assigns comparable ratings that are used for compliance with the fund&#x2019;s investment policies.&lt;/div&gt;&lt;div style="margin-top: 0; font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 4pt; margin-left: 32pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;&#x2020;&lt;/div&gt; Includes derivatives.&lt;/div&gt;&lt;/div&gt;</oef:HoldingsTableTextBlock>

In assigning a credit rating to a security, the fund looks specifically to the ratings assigned to the issuer of the security by Standard &amp;amp; Poor&#x2019;s, Moody&#x2019;s and/or Fitch. If agency ratings differ, the security will be considered to have received the highest of those ratings, consistent with the fund&#x2019;s investment policies. Securities in the &#x201c;unrated&#x201c; category (above) have not been rated by a rating agency; however, the investment adviser performs its own credit analysis and assigns comparable ratings that are used for compliance with the fund&#x2019;s investment policies.&lt;/div&gt;&lt;div style="margin-top: 0; font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 4pt; margin-left: 32pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;&#x2020;&lt;/div&gt; Includes derivatives.&lt;/div&gt;&lt;/div&gt;</oef:HoldingsTableTextBlock>
