Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•High-yield bonds achieved a strong gain for the 12 months ending August 31, 2025, helped by resilient fundamentals, falling yields, compressed spreads and a steady economy against the backdrop of a possible September rate cut.

•Against this backdrop, the fund's core investment in high-yield bonds gained 8.45% and contributed to performance versus the ICE BofA US High Yield Constrained Index for the fiscal year. By industry, security selection was the primary contributor, led by telecommunications. Security selection in real estate and automotive also boosted the fund's relative performance.

•The top individual relative contributor was an overweight in EchoStar (+86%). The second-largest relative contributor was our stake in Windstream (+27%), which was not held at period end. A non-benchmark stake in Rivian gained 24% and notably helped.

•In contrast, the biggest detractor from performance versus the benchmark was security selection in health care. Also hurting our result were security selection and an overweight in utility and security selection and an underweight in media.

•The biggest individual relative detractor was an overweight in Sunnova Energy (-100%). A second notable relative detractor was our stake in Bausch Health (+2%).

•Notable changes in positioning include increased exposure to the health care industry and a lower allocation to capital goods.

Application of FMR's environmental, social and governance 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.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection in the utility industry was the primary detractor from the fund's performance versus the ICE U.S. All Capital Securities Constrained Custom Index for the fiscal year. Security selection in real estate hampered the fund's relative result to a much lesser extent.

•The largest individual relative detractor was an overweight in Southern (-7%). This period we increased our position in Southern, which was one of the fund's biggest holdings. A second notable relative detractor was an overweight in SCE Trust VI (-16%). This period we increased our position in SCE Trust VI. A non-index stake in U.S. Treasury bonds returned -1% and notably hurt.

•In contrast, the biggest contributors to performance versus the index were security selection and an overweight in energy. Picks in consumer goods and financial services also boosted the fund's relative result.

•The top individual relative contributor was an overweight in Enbridge (+10%). This period we increased our stake in Enbridge. The company was the top holding this period. The second-largest relative contributor was an overweight in Energy Transfer (+9%). It was the fund's largest holding at period end. Not owning QVC Group, an index component that returned -81%, was another notable relative contributor.

•Notable changes in positioning include decreased exposure to the sovereign industry and a higher allocation to utility.
