The full 12-month period was marked by high volatility.&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;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;Against this backdrop, the fund's strategy of overweighting corporate bonds, while underweighting U.S. Treasurys, contributed to its performance versus the composite index. Within corporates, debt holdings among financial institutions - especially banks - and industrial firms, particularly in the consumer cyclical segment, added notable value.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;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;Non-composite exposure to asset-backed securities, including car loan debt and credit card receivables, also meaningfully contributed. A small, out-of-index allocation to commercial mortgage-backed securities helped as well.&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;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;In contrast, the fund's yield-curve positioning detracted from relative performance.&#160;&#160;&lt;/span&gt;&lt;/div&gt;
&lt;div style="text-align:left;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;At period end, corporates made up about 33% of fund assets, up from roughly 26% a year ago and notably overweight versus the composite index average of 17%. Exposure to U.S. Treasurys stood at 49% at the end of the fiscal year, compared with an average of 75% for the composite index, while out-of-index exposure to asset-backed securities composed roughly 13% of fund assets as of August 31.&#160;&lt;/span&gt;&lt;/div&gt;
