**What were your Fund costs for the last year?**

| Fidelity® Sustainable Target Date 2015 Fund  | $44  | 0.42% |

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**How did the Fund perform over the life of Fund?**

**CUMULATIVE PERFORMANCE**

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**How did the Fund perform over the life of Fund?**

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**How did the Fund perform over the life of Fund?**

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**How did the Fund perform over the life of Fund?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

**What affected the Fund's performance this period?**

• Global risk assets posted strong gains for the 12 months ending March 31, 2026, supported by healthy corporate fundamentals in several regions, a resilient global economy, robust corporate spending on artificial intelligence and dovish monetary policy from some central banks, though momentum faded in late February, as conflict in the Middle East took center stage.

• Against this backdrop, an overweight positioning in non-U.S. equities and investment performance among the underlying U.S. equity portfolio notably contributed to the fund's performance versus the composite index for the fiscal year. Also helping on a relative basis was an underweight positioning, on average, in U.S. investment-grade bonds.

• From an underlying portfolio standpoint, the largest individual relative contributor this period was an investment in Fidelity® Series Sustainable U.S. Markets Fund (+21.93%), which outpaced its benchmark, the MSCI USA IMI ESG Focus Dynamic Weighted Index (+18.10%) for the 12 months.

• Also contributing was Fidelity® Series Sustainable Emerging Markets Fund (+34.95%), which topped the 29.50% return of its benchmark, the MSCI EM ESG Focus Index.

• In contrast, investment performance in the underlying non-U.S. developed-markets equities portfolio detracted from the Fund's relative result. Here, Fidelity® Series Sustainable Non-U.S. Developed Markets Fund (+19.09%) trailed its benchmark, the MSCI World ex USA ESG Focus Index (+22.24%).

• An overweight allocation to long-term U.S. Treasury bonds also hurt the Fund's relative performance this period.

*Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.*

The trust's Audit Committee has considered non-audit services that were not pre-approved that were provided by PwC to Fund Service Providers to be compatible with maintaining the independence of PwC in its(their) audit of the Fund(s), taking into account representations from PwC, in accordance with Public Company Accounting Oversight Board rules, regarding its independence from the Fund(s) and its(their) related entities and FMR's review of the appropriateness and permissibility under applicable law of such non-audit services prior to their provision to the Fund(s) Service Providers.

<u>Audit Committee Pre-Approval Policies and Procedures</u>

The trust's Audit Committee must pre-approve all audit and non-audit services provided by a fund's independent registered public accounting firm relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee's consideration of non-audit services by the audit firms that audit the Fidelity funds. The policies and procedures require that any non-audit service provided by a fund audit firm to a Fidelity fund and any non-audit service provided by a fund auditor to a Fund Service Provider that relates directly to the operations and financial reporting of a Fidelity fund ("Covered Service") are subject to approval by the Audit Committee before such service is provided.

All Covered Services must be approved in advance of provision of the service either: (i) by formal resolution of the Audit Committee, or (ii) by oral or written approval of the service by the Chair of the Audit Committee (or if the Chair is unavailable, such other member of the Audit Committee as may be designated by the Chair to act in the Chair's absence). The approval contemplated by (ii) above is permitted where the Treasurer determines that action on such an engagement is necessary before the next meeting of the Audit Committee.

Non-audit services provided by a fund audit firm to a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund are reported to the Audit Committee periodically.

<u>Non-Audit Services Approved Pursuant to Rule 2-01(c)(7)(i)(C) and (ii) of Regulation S-X ("De Minimis Exception")</u>

There were no non-audit services approved or required to be approved by the Audit Committee pursuant to the De Minimis Exception during the Fund's(s') last two fiscal years relating to services provided to (i) the Fund(s) or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Fund(s).

The Registrant has not retained, for the preparation of the audit report on the financial statements included in the Form N-CSR, a registered public accounting firm that has a branch or office that is located in a foreign jurisdiction and that the Public Company Accounting Oversight Board (the "PCAOB") has determined that the PCAOB is unable to inspect or investigate completely because of a position taken by an authority in the foreign jurisdiction.

The Registrant is not a "foreign issuer," as defined in 17 CFR 240.3b-4.

**Notes to Financial Statements**

For the period ended March 31, 2026

**1. Organization.**

Fidelity Sustainable Target Date Retirement Fund (formerly Fidelity Sustainable Target Date Income Fund), Fidelity Sustainable Target Date 2010 Fund, Fidelity Sustainable Target Date 2015 Fund, Fidelity Sustainable Target Date 2020 Fund, Fidelity Sustainable Target Date 2025 Fund, Fidelity Sustainable Target Date 2030 Fund, Fidelity Sustainable Target Date 2035 Fund, Fidelity Sustainable Target Date 2040 Fund, Fidelity Sustainable Target Date 2045 Fund, Fidelity Sustainable Target Date 2050 Fund, Fidelity Sustainable Target Date 2055 Fund, Fidelity Sustainable Target Date 2060 Fund, Fidelity Sustainable Target Date 2065 Fund and Fidelity Sustainable Target Date 2070 Fund (the Funds) are funds of Fidelity Aberdeen Street Trust (the Trust). The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust. Each Fund is authorized to issue an unlimited number of shares. Each Fund offers Class A, Class M, Class C, Fidelity Sustainable Target Date, Class K, Class K6, Class I and Class Z, each of which has equal rights as to assets and voting privileges. Class Z6 was consolidated into Class K6 on May 24, 2024. Class A, Class M, Class C, Class I and Class Z are Fidelity Advisor classes. Each class has exclusive voting rights with respect to matters that affect that class. Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions.

Each Fund is a fund of funds, and therefore invests in other funds instead of individual securities. Each Fund invests primarily in a combination of Fidelity U.S. equity funds, international equity funds, bond funds, and short-term funds.

**2. Significant Accounting Policies.**

Each Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 *Financial Services - Investment Companies*. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Each Fund operates as a single operating segment. Each Fund's income, expenses, assets, and performance are regularly monitored and assessed as a whole by the investment adviser and other individuals responsible for oversight functions of the Trust, using the information presented in the financial statements and financial highlights. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. Each Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of each Fund:

**Investment Valuation.** Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. Each Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value each Fund's investments by major category are as follows:

Investments in open-end mutual funds are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

The aggregate value of investments by input level as of March 31, 2026 is included at the end of each Fund's Schedule of Investments.

**Investment Transactions and Income.** For financial reporting purposes, the Funds' investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from any underlying mutual funds or exchange-traded funds are recorded on the ex-dividend date. Distributions from any underlying mutual funds or exchange-traded funds that are deemed to be return of capital are recorded as a reduction of cost of investments.

**Class Allocations and Expenses.** Investment income, realized and unrealized capital gains and losses, common expenses of a fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of a fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred, as applicable. Certain expense reductions may also differ by class, if applicable. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

**Income Tax Information and Distributions to Shareholders.** Each year, each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of March 31, 2026, each Fund did not have any unrecognized tax benefits in the financial statements; nor is each Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. In addition, certain funds claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to the short-term gain distributions from the underlying mutual funds or exchange-traded funds (ETFs), capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows for each Fund:

---

**5. Fees and Other Transactions with Affiliates.**

**Management Fee and Expense Contract.** Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Funds with investment management related services. Under the management contract, each Class of each Fund pays a monthly management fee that is set at an annual rate by referring to each Fund's target date, indicated by its name, such that the management fee rate applicable to each Class of each Fund is reduced as the fund approaches, and then passes, its target date. In addition, under the management contract, the investment adviser pays all ordinary operating expenses of each Fund, except distribution and service plan fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses. For the reporting period, the total annual management fee rate for each Class of each Fund was as follows:

**8. Other.**

A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.

**9. Risk and Uncertainties.**

Many factors affect a fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance. The effects of these developments to a fund will be impacted by the types of securities in which a fund invests, the financial condition, industry, economic sector, and geographic location of an issuer, and a fund's level of investment in the securities of that issuer. Significant concentrations in security types, issuers, industries, sectors, and geographic locations may magnify the factors that affect a fund's performance.

***Basis for Opinions***

These financial statements are the responsibility of the Funds' management. Our responsibility is to express an opinion on the Funds' financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2026 by correspondence with the custodian and broker; when replies were not received from the broker, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

## Ex-99.Code

**Fidelity Investments**

**FIDELITY FUNDS'**

**CODE OF ETHICS**

**FOR PRESIDENT, TREASURER**

**AND PRINCIPAL ACCOUNTING OFFICER**

2023

**FIDELITY FUNDS' CODE OF ETHICS FOR**

**PRESIDENT, TREASURER AND PRINCIPAL ACCOUNTING OFFICER**

**I. Purposes of the Code/Covered Officers**

This document constitutes the Code of Ethics (Code) adopted by the Fidelity Funds (Funds) pursuant to Section 406 of the Sarbanes-Oxley Act of 2002. The Code applies to the Fidelity Funds' President and Treasurer, and Chief Financial Officer (Covered Officers). Fidelity's Ethics Office, within Enterprise Compliance, administers the Code.

The purposes of the Code are to deter wrongdoing and to promote, on the part of the Covered Officers:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· full, fair, accurate, timely and understandable disclosure in reports and documents that the Fidelity Funds submit to the Securities and Exchange Commission (SEC), and in other public communications by a Fidelity Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· compliance with applicable laws and governmental rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the prompt internal reporting to an appropriate person or persons identified in the Code of violations of the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

**II.** **Covered Officers Should Handle Ethically** 

**Actual and Apparent Conflicts of Interest**

**Overview.** A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or their service to, the Fidelity Funds. For example, a conflict of interest would arise if a Covered Officer, or a member of their family, receives improper personal benefits as a result of their position with the Fidelity Funds.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fidelity Funds and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (Investment Company Act) and the Investment Advisers Act of 1940 (Investment Advisers Act). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with a Fidelity Fund because of their status as "affiliated persons" of the Fund. Separate compliance programs and procedures of the Fidelity Funds, Fidelity Management & Research Company (FMR) and the other Fidelity companies are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fidelity Funds and FMR (or another Fidelity company) of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fidelity Funds, FMR or another Fidelity company), be involved in establishing policies and implementing decisions that have different effects on the Fidelity Funds, FMR and other Fidelity companies. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fidelity Funds and FMR (or another Fidelity company) and is consistent with the performance by the Covered Officers of their duties as officers of the Fidelity Funds. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Funds' Board of Trustees (Board) that the Covered Officers also may be officers or employees of one or more other Fidelity Funds covered by this Code.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of a Fidelity Fund.

\* \* \*

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· not use their personal influence or personal relationships improperly to influence investment decisions or financial reporting by any Fidelity Fund whereby the Covered Officer would benefit personally to the detriment of any Fidelity Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· not cause a Fidelity Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fidelity Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· not engage in any outside business activity, including serving as a director or trustee, that prevents the Covered Officer from devoting appropriate time and attention to the Covered Officer's responsibilities with the Fidelity Funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· not have a consulting or employment relationship with any of the Fidelity Funds' service providers that are not affiliated with Fidelity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· not retaliate against any employee or Covered Officer for reports of actual or potential misconduct, which are made in good faith.

With respect to other fact patterns, if a Covered Officer is in doubt, other potential conflict of interest situations should be described immediately to the Fidelity Ethics Office for resolution. Similarly, any questions a Covered Officer has generally regarding the application or interpretation of the Code should be directed to the Fidelity Ethics Office immediately.

**III. Disclosure and Compliance**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Each Covered Officer should familiarize themself with the disclosure requirements generally applicable to the Fidelity Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about any Fidelity Fund to others, whether within or outside Fidelity, including to the Board and auditors, and to governmental regulators and self-regulatory organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Each Covered Officer should, to the extent appropriate within their area of responsibility, consult with other officers and employees of the Fidelity Funds, FMR and the Fidelity service providers, and with the Board's Compliance Committee, with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fidelity Funds file with, or submit to, the SEC and in other public communications made by the Fidelity Funds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

**IV. Reporting and Accountability**

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· upon receipt of the Code, and annually thereafter, submit to the Fidelity Ethics Office an acknowledgement stating that they have received, read, and understand the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· notify the Fidelity Ethics Office promptly if they know of any violation of the Code. <u>Failure to do so is itself a violation of this Code</u>.

The Fidelity Ethics Office shall take all action it considers appropriate to investigate any actual or potential violations reported to it. Upon completion of the investigation, if necessary, the matter will be reviewed with senior management or other appropriate parties, and a determination will be made as to whether any action should be taken as detailed below. The Covered Officer will be informed of any action determined to be appropriate. The Fidelity Ethics Office will inform the Personal Trading Committee of all Code violations and actions taken in response. Without implied limitation, appropriate remedial, disciplinary or preventive action may include a written warning, a letter of censure, suspension, dismissal or, in the event of criminal or other serious violations of law, notification of the SEC or other appropriate law enforcement authorities. Additionally, other legal remedies may be pursued.

The policies and procedures described in the Code do not create any obligations to any person or entity other than the Fidelity Funds. The Code is intended solely for the internal use by the Fidelity Funds and does not constitute a promise, contract or an admission by or on behalf of any Fidelity Fund as to any fact, circumstance, or legal conclusion. The Fidelity Funds, the Fidelity companies and the Fidelity Head of Ethics retain the discretion to decide whether the Code applies to a specific situation, and how it should be interpreted.

**V. Oversight**

Material violations of this Code will be reported promptly by FMR (or another Fidelity company) to the Board's Compliance Committee. In addition, at least once each year, FMR (or another Fidelity company) will provide a written report to the Board, which describes any issues arising under the Code since the last report to the Board, including, but not limited to, information about material violations of the Code and action taken in response to the material violations.

**VI. Other Policies and Procedures** 

This Code shall be the sole code of ethics adopted by the Fidelity Funds for purposes of Section 406 of the Sarbanes-Oxley Act. Other Fidelity policies or procedures that cover the behavior or activities of Covered Officers are separate requirements applying to the Covered Officers (and others) and are not part of this Code.

**VII. Amendments**

Any material amendments or changes to this Code must be approved or ratified by a majority vote of the Board, including a majority of the Trustees who are not interested persons of the Fidelity Funds.

**VIII. Records and Confidentiality**

Records of any violation of the Code and of the actions taken as a result of such violations will be kept by the Fidelity Ethics Office. All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Fidelity Ethics Office, the Personal Trading Committee, the Board, appropriate personnel at the relevant Fidelity company or companies and the legal counsel of any or all of the foregoing.
