When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. If a security is not rated by Moody's, S&amp;amp;P and Fitch, but has a rating by Kroll and/or DBRS, the same methodology is applied to those bonds that would otherwise be not rated. When a bond is not rated by any rating agency, it is designated as &#x201c;Not rated.&#x201d; Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily.&lt;/div&gt;&lt;div style="border-bottom-width: 0.5pt; border-bottom-style: solid; font-family: 'ITCFrankGothForAMPF-Md'; color: rgb(0, 63, 107); text-transform: none; letter-spacing: normal; font-size: 10pt; border-bottom-color: rgb(190, 231, 248); text-align: center; margin-bottom: 5pt; margin-top: 5pt; padding-bottom: 5pt;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;Credit &lt;div style="display:inline;"&gt;Quality&lt;/div&gt;&lt;div style="display:inline;"&gt;&lt;/div&gt;&lt;/div&gt; &lt;/div&gt;&lt;div style="padding-right: 6pt; padding-left: 6pt;"&gt;&lt;div style="padding-right: 6pt; padding-left: 6pt;"&gt;&lt;img alt="Graphical Representation - Allocation 1 Chart" src="chartimages_3318005.jpg" style="width: 172.8pt;"/&gt;  &lt;/div&gt;&lt;/div&gt;</oef:CreditQualityExplanationTextBlock>
