The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August,&lt;div style="display:inline;"&gt; and&lt;/div&gt; hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;  &lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt; &lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt; </oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

Any market index shown is unmanaged, and therefore, has no expenses. Investors cannot invest directly in an index. Source(s): Bloomberg Index Services Ltd.&lt;/div&gt;</oef:AvgAnnlRtrTableTextBlock>

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has sel&lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;ec&lt;/div&gt;ted the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class T shares were first offered on April 7, 2017.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;Bloomberg &lt;/div&gt;75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;particularly &lt;/div&gt;additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class F-3 shares were first offered on January 27, 2017.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;during &lt;/div&gt;the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;market &lt;/div&gt;index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;Securitized &lt;/div&gt;Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class 529-T shares were first offered on April 7, 2017.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;re&lt;/div&gt;sults to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change.

The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class 529-F-2 shares were first offered on October 30, 2020.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class 529-F-3 shares were first offered on October 30, 2020.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

Any market index shown is &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;unmanaged&lt;/div&gt;, and therefore, has no expenses. Investors cannot invest directly in an index.

The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

Any market index shown is unmanaged, and therefore, has no expenses. Investors cannot invest directly in an index. Source(s): Bloomberg Index Services Ltd.&lt;/div&gt;</oef:AvgAnnlRtrTableTextBlock>

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;75&lt;/div&gt;% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;1&lt;/div&gt; Class R-5E shares were first offered on November 20, 2015.&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: 0; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;2&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;fund&#x2019;s &lt;/div&gt;primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

The Fed&#x2019;s potential move comes as inflation has cooled, hitting a three-year low in August, and hiring has slowed. Corporate issuance continued apace during the period.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;Within the fund, each sector contributed positively to overall returns. The fund&#x2019;s holdings in mortgage-backed securities and other asset-backed securities were particularly additive to results during the period. Corporate bonds also helped the fund&#x2019;s absolute returns.&lt;/div&gt;&lt;div style="margin-top: 0; font-weight: normal; font-family: 'Arial'; font-size: 9pt; line-height: 11pt; letter-spacing: -0.04pt; color: rgb(0, 0, 0); margin-bottom: 4.0032pt;"&gt;The fund&#x2019;s overall duration positively contributed to relative returns compared to the benchmark. However, its strategic allocation of bond investments across different maturities, known as yield curve positioning, slightly detracted from results. This was due to less favorable yield movements for longer-duration securities compared to shorter-duration ones amid the yield curve shifts during the period.&lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

margin-bottom: 0;"&gt;Effective July 24, 2024, the fund&#x2019;s primary benchmark changed from the Bloomberg U.S. Government/Credit 1&#x2013;7 Years ex BBB Index to the Bloomberg U.S. Aggregate Index, a broad-based index that represents the overall applicable securities market, as required by the SEC. There is no change in the fund&#x2019;s investment strategies as a result of the benchmark change. The fund has selected the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index to replace the Bloomberg U.S. &lt;div style="letter-spacing: 0px; top: 0px;display:inline;"&gt;Government&lt;/div&gt;/Credit 1&#x2013;7 Years ex BBB Index as its secondary market index. The fund&#x2019;s investment adviser believes that the Bloomberg 75% Government Credit 1&#x2013;7 Years 25% Securitized Index provides a means to compare the fund&#x2019;s results to a benchmark that is more representative of the fund&#x2019;s investment universe.&lt;/div&gt;&lt;div style="font-family: 'Arial'; font-weight: normal; font-size: 8pt; line-height: 10pt; color: rgb(0, 0, 0); margin-bottom: 0; margin-top: 6.5pt; margin-left: 5pt; text-indent: -5pt;"&gt;&lt;div style=";display:inline;vertical-align: super;font-size:7.4px"&gt;*&lt;/div&gt; Investment results assume all distributions are reinvested and reflect applicable fees and expenses.
