&lt;div style="text-align:left;text-align-last:auto;text-indent:-24px;margin-bottom:2px;margin-left:24px;margin-top:5px;margin-right:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;The fund's "carry" advantage, meaning its proportionately larger stake in higher-yielding bonds, helped.&lt;/span&gt;&lt;/div&gt;

Fund holdings are priced by a third-party pricing service and validated daily by Fidelity Management &amp;amp; Research's fair-value processes. Securities within the index, however, are priced by the index provider. These two approaches employ somewhat different methodologies in setting the prices of municipal securities, most of which trade infrequently.&lt;/span&gt;&lt;/div&gt;
