Fidelity High Income Fund

Fidelity High Income Fund Key Takeaways For the fiscal year ending April 30, 2018, the fund gained 4.27%, topping the 3.22% advance of its benchmark, the ICE BofAML US High Yield Constrained Index. Portfolio Manager Frederick Hoff is happy with the fund's outperformance of the benchmark the past 12 months. He partly attributes it to his willingness to take advantage of market volatility, especially in the energy sector, where he found several opportunities due to a falling oil price and lower bond valuations. Compared with the benchmark, the fund was helped most by security selection in energy, utilities, technology and capital goods. Overweighting utilities and banks & thrifts also helped. Looking at credit quality, security selection among bonds rated B and CCC/C contributed. In the lagging BB tier, the fund benefited from underweighting the category, as well as modestly helpful bond picking within it. During the period, Fred temporarily moved to an overweighting in the energy sector, based on attractive valuations, but shifted back to a modest underweighting as the price of oil rose and valuations became less attractive to him. As of April 30, Fred acknowledged higher valuations in the highyield market but continued to see opportunity in the asset class. MARKET RECAP U.S. corporate high-yield bonds gained 3.22% for the 12 months ending April 30, 2018, as measured by the ICE BofAML US High Yield Constrained Index. High-yield bonds began the period on a strong note and maintained momentum into July, rising along with other risk assets. Although heightened geopolitical risk and some industryspecific developments hampered high yield for a brief stretch in early August, the favorable environment for risk assets in the first half of the period generally prevailed overall, as the index continued on an uptrend through the end of 2017. High yield began the new year by extending its rise, but reversed course in early February and continued downward in March amid broad-based market volatility. The short-term decline was largely attributable to a policy rate hike by the U.S. Federal Reserve, a selloff in technology shares and an escalating trade dispute with China. For the full 12 months, lower-quality bonds within the index advanced 7%, topping credits rated B (+3%) and BB (+2%). By industry, gains were broad-based, with steel (+6%), chemicals (+4%) and metals/mining (+4%) boosted by the potential for increased infrastructure spending in the U.S. The index's largest component the past year, energy, rose about 5% amid higher oil prices. Notable laggards included cable/satellite TV (-1%), consumer products (0%) and telecommunications (+1%). Not FDIC Insured May Lose Value No Bank Guarantee

Q&A An interview with Portfolio Manager Frederick Hoff Fund Facts Trading Symbol: Frederick Hoff Portfolio Manager SPHIX Start Date: August 29, 1990 Size (in millions): $4,309.34 Investment Approach Fidelity High Income Fund is a diversified high-yield bond strategy focused on investing primarily in the bonds of non-investment-grade companies. We apply a core investment approach, with a high concentration in B-rated securities, the heart of the highyield market, where we believe research can be highly leveraged in seeking to achieve consistent risk-adjusted returns over a full credit cycle. In particular, we favor companies with strong balance sheets, improving business/industry fundamentals and strong management teams, focusing on the best values within the capital structure. In doing so, we take a longer-term investment outlook, with an eye to where we are in the credit cycle. We strive to uncover these companies through in-depth fundamental credit analysis, working in concert with Fidelity's high-income and global research teams, with the goal of identifying attractive risk/reward opportunities in the market. Q: Fred, how did the fund perform for the fiscal year ending April 30, 2018 The fund gained 4.27%, outpacing the 3.22% result of its benchmark, the ICE BofAML US High Yield Constrained Index. The fund outperformed the peer group average by a slightly wider margin. Versus the benchmark, the fund benefited from security selection in energy and utilities, as well as in technology and capital goods. Overweightings in utilities and banks & thrifts also contributed, as these industries outperformed. On a credit-quality basis, the fund benefited most from very good security selection among B-rated issues, followed by my picks in the CCC/C tier. In the lagging BB tier of the market, we benefited from underweighting this category, as well as from modestly helpful bond picking. Q: How would you assess the fund's result I'm pleased that the fund outperformed the high-yield index during a volatile market environment. Coming into the period, I was confident in the fundamental characteristics of the businesses we were investing in, and I'm happy we proved able to find companies that were successfully improving their earnings over time. To remind shareholders of the approach I follow in all types of market backdrops: I favor issuers with strong business fundamentals, well-defined business plans and the potential to improve their credit quality over time. My approach is long term in nature, normally based on an investment horizon of at least two years, as I believe this allows time for companies to generate cash flow or initiate corporate actions to improve their balance sheets. Also, my investment process generally leads me to limit the fund's exposure to the lowest-rated issues. When I do invest here, I rely heavily on the capabilities of Fidelity's high-yield credit research team, trying to find bonds that offer suitable potential reward relative to the securities' risks. Q: How did you implement this strategy in response to market conditions Applying our bottom-up (bond-by-bond) research process, I found various opportunities to capitalize upon market 2 For definitions, fund risks and other important information, please see the Definitions and Important Information section of this Q&A.

volatility by investing in issuers whose debt was temporarily priced well below what I thought was warranted. The most notable of these opportunities came in the energy industry. I typically underweight this area, because I don't like the combination of high financial leverage combined with exposure to commodity-price volatility that many energy issuers have, especially exploration and production companies. However, in the first half of 2017, as the per-barrel price of oil dropped to the low $40s, I thought the risk/reward tradeoff was starting to make good sense for a number of issuers, whose bond prices were not accurately capturing what I saw as the companies' good long-term asset values. Thus, as I added aggressively to the fund's position in energy, the fund moved from a previously large underweighting in the industry to an overweighting by November 2017. This move proved well-timed. As I was building this larger energy position, the price of oil was rising, as global inventories started to shrink amid healthy demand for the commodity. Bonds of many energy issuers regained some of their lost value, boosting the fund's relative result. More recently, as the price of oil has risen dramatically lifting bond valuations along with it the risk/reward tradeoff among many of the issuers I had favored began to look less favorable to me. So, I again reduced the fund's exposure to energy, finishing the fund's fiscal year at slightly less than that of the benchmark. Other, less-pronounced investment themes this period included reducing exposure to issuers in the telecommunications industry, which we believe is maturing and features increased risk for several incumbent wireline carriers. I also added a bit more cash, which, among other benefits, provided the fund with some more capital to reinvest should attractive opportunities emerge in a morevolatile market. Q: How else did your portfolio positioning change the past 12 months Following my bottom-up approach, the fund's exposure to the B credit tier of the market grew from about 45% to 49% of the fund. I regularly overweight this area of the market, as my approach emphasizes the simultaneous monitoring of interest rate risk and credit risk. High-yield bonds with higher credit ratings tend to be more sensitive to changes in interest rates, experiencing more volatility because of their typically lower yields. Conversely, lower-rated issues generally are less affected by movement in rates, although this area of the market has more credit risk and can suffer disproportionately, should an issuer's financial position weaken. This helps to explain why I like B-rated bonds. They are in the middle of the quality spectrum and, in my opinion, provide a reasonable balance between interest rate risk and credit risk. Later, I'll have a bit more to say about how I handled the fund's exposure to rising interest rates. Q: Which investments notably influenced performance versus the benchmark Our top individual relative contributor was Bi-Lo, a supermarket operator that made very good progress in its financial restructuring and also reported better-thanexpected financial results. In March, Bi-Lo announced it had filed for bankruptcy protection, and, as part of the agreement, some of our debt was to be converted to equity in the company. Another troubled grocery store operator, however, Tops, did not fare well and hurt our relative result. We ultimately sold our position in Tops, anticipating a painful restructuring process for the firm. Another strong-performing holding was Dynegy, whose bonds rose after the company agreed last October to be acquired by Vistra Energy. The transaction ultimately closed in April. As I mentioned, bond selection was strong in the energy industry, led by California Resources Group, Denbury and Frac Tech, all of which benefited from a rising oil price. In contrast, our biggest individual detractor was Community Health Systems, a highly levered hospital provider that continued to experience margin declines, as well as a drop in patient admissions. Of final note, relative performance was hurt by an underweighting in Intelsat, a satellite provider that benefited from investors' increased optimism about the company's financial prospects, even as we continued to see a challenging risk/reward environment for the firm and remained underweight in the name at period end. Q: What's your outlook as of April 30, Fred I think the fund is reasonably well-positioned for the current economic environment. Even though valuations are no longer particularly cheap, credit spreads remain decent, with the market yielding roughly double the yield of 10-year U.S. Treasuries. We're keeping close watch for any signs of an economic slowdown, but aren't yet seeing concerning data on this front. Even as rising rates are worth monitoring, I'm generally optimistic about the medium-term prospects for the credit quality of high-yield issuers. 3 For definitions, fund risks and other important information, please see the Definitions and Important Information section of this Q&A.

LARGEST HOLDINGS BY ISSUER Fred Hoff on how he's managing interest rate risk: "These days, the market is very focused on interest rate risk, given concern about inflation and the U.S. Federal Reserve's continued program of short-term rate hikes. Rising rates is always a concern for bonds, but I'd note that rates and inflation expectations are higher due to increased economic activity a good thing for issuer credit quality. Investors' main fear seems to be that the Fed could overshoot and raise rates too high, ultimately triggering recession. I don't see any immediate signs of that happening. "In the meantime, I've taken a few steps to help insulate the fund from the effects of rising interest rates. First, I've managed the fund's duration its sensitivity to interest rates by adding shorter-term bonds and increasing cash in the portfolio. "Second, at period end, the fund included a roughly 5% stake in floating-rate bank loans. These securities lack sensitivity to interest rates because their coupon income regularly resets along with rate changes. "Third, I've maintained a higher-than-normal allocation to commodity-oriented industries, such as energy, metals/mining and chemicals, all of which tend to benefit from higher inflation. "Although we like to limit interest rate risk in the portfolio, we do tend to be relatively comfortable taking on credit risk. This preference often entails underweighting the highest tier of the high-yield market which tends to feature lower coupons and more interest rate sensitivity and relying on our research capabilities to find fundamentally strong high-yield issuers with what we believe are good long-term prospects."

Definitions and Important Information Unless otherwise disclosed to you, in providing this information, Fidelity is not undertaking to provide impartial investment advice, act as an impartial adviser, or to give advice in a fiduciary capacity. DIVIDENDS AND YIELD 30-Day SEC Restated Yield is the fund's 30-day yield without applicable waivers or reimbursements, stated as of month-end. 30-day SEC Yield is a standard yield calculation developed by the Securities and Exchange Commission for bond funds. The yield is calculated by dividing the net investment income per share earned during the 30-day period by the maximum offering price per share on the last day of the period. The yield figure reflects the dividends and interest earned during the 30-day period, after the deduction of the fund's expenses. It is sometimes referred to as "SEC 30-Day Yield" or "standardized yield". Dividends per share show the income paid by the fund for a set period of time. If you annualize this number, you can compare the fund's income over different periods. FUND RISKS The fund's yield and share price change daily and are based on changes in interest rates and market conditions, and in response to other economic, political, or financial developments. Foreign markets, particularly emerging markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. In general, bond prices rise when interest rates fall, and vice versa. This effect is usually more pronounced for longer-term securities. The fund may invest in lower-quality debt securities which generally offer higher yields, and carry more risk. You may have a gain or loss when you sell your shares.
