Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the twelve months ended October 31, 2025, Class A shares of Franklin Convertible Securities Fund returned 16.44%. The Fund compares its performance to the ICE BofA Convertibles Total Return Alternatives Index, which returned 25.63% for the same period.
PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
The Fund posted widespread gains as nine out of 11 sector allocations added to its absolute returns. The most impressive gains were provided by convertible bond holdings in the information technology (IT), health care, consumer discretionary, industrials and materials sectors. When combined, these allocations covered just over two-thirds of the portfolio (on average).
↑
Select outliers to the upside gained more than 60%, including key contributors Axon Enterprise in the industrials sector, Snowflake in IT, Wayfair and The RealReal in consumer discretionary, and Mirum Pharmaceuticals (sold by period-end) in health care.
↑
In general, the Fund was supported by robust new convertible security issuance—especially in the U.S.—and strong investor demand as issuers used convertibles to refinance higher-cost debt, plus favorable conditions for growth-sector equities and occasional bouts of elevated volatility, which typically boosts the embedded option value (i.e., the worth of the bondholder’s right to convert the bond into shares of the issuing company’s stock at a set price).
Top detractors from performance:
↓
Holdings in the consumer staples and financials sectors had mixed results and collectively failed to advance, but their negative impact on absolute performance was minimal by comparison to the Fund’s overall gains. Freshpet was a major detractor in consumer staples, while Shift4 Payments and Apollo Global Management anchored the downside in financials.
↓
The other key detractors reduced the Fund’s gains within sectors that were net contributors, including Wolfspeed and BILL Holdings in IT; Integer Holdings, which was the sole outlier to the downside in health care (countered by 13 net contributors); Booking Holdings (sold by period-end) in consumer discretionary; and Zillow Group (sold by period-end), which was our only detractor in real estate.
↓
Overall, the U.S. and global convertible markets faced a few challenges during an otherwise strong year driven by broad-based gains and healthy new issuance. The short list of detrimental factors included pressure from elevated interest rates and relatively weak small- and mid-capitalization equity performance, along with some issuance caution amid geopolitical/trade-policy risk, which constrained upside and widened spreads.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the twelve months ended October 31, 2025, Class A shares of Franklin Equity Income Fund returned 13.95%. The Fund compares its performance to the Russell 1000 Value Index and the S&P 500 Index, which returned 11.15% and 21.45%, respectively, for the same period.  
PERFORMANCE HIGHLIGHTS
Top contributors to absolute performance:
↑
The financials, information technology (IT) and industrials sectors contributed most to absolute performance over the period. In the financials sector, the recovery in capital markets, improvement in the economic growth outlook following initial fears about tariffs in April and expectations of interest rate cuts lifted shares of JPMorgan Chase and Morgan Stanley.
↑
In the IT sector, chipmaker Broadcom was a top contributor. Demand for artificial intelligence (AI)-related semiconductors remained quite strong. Expectations for cash flow and earnings continued to rise throughout the period under review.
↑
In the industrials sector, RTX was a meaningful contributor delivering robust performance along with solid earnings and optimistic guidance. Overall, contractors that make weapons and defense equipment rallied during the period with growth driven by rising global defense budgets.
Top detractors from absolute performance:
↓
The health care and materials sectors were the only detractors from absolute performance. The health care sector was particularly hard hit by an investment in UnitedHealth Group. The health insurer’s stock declined following several notable events, including the resignation of the company’s chief executive officer, the withdrawal of its 2025 outlook and an investigation by the U.S. Department of Justice into its billing practices. The Fund significantly reduced exposure over the period.
↓
While IT and industrials were leading contributors to returns, these sectors included several detractors that hurt fund performance. A position in Texas Instruments hindered returns in the IT sector. A slow recovery in key markets along with competition from AI-focused peers weighed on the chipmaker.
↓
A slowdown in volume hindered results for United Parcel Service in the industrials sector, which the Fund exited over the period. A decline in full-year revenue, structural challenges and trade headwinds kept pressure on the package delivery company.

The health insurer’s stock declined following several notable events, including the resignation of the company’s chief executive officer, the withdrawal of its 2025 outlook and an investigation by the U.S. Department of Justice into its billing practices. The Fund significantly reduced exposure over the period.
↓
While IT and industrials were leading contributors to returns, these sectors included several detractors that hurt fund performance. A position in Texas Instruments hindered returns in the IT sector. A slow recovery in key markets along with competition from AI-focused peers weighed on the chipmaker.
↓
A slowdown in volume hindered results for United Parcel Service in the industrials sector, which the Fund exited over the period. A decline in full-year revenue, structural challenges and trade headwinds kept pressure on the package delivery company.

PERFORMANCE HIGHLIGHTS
Top contributors to absolute performance:
↑
The financials, information technology (IT) and industrials sectors contributed most to absolute performance over the period. In the financials sector, the recovery in capital markets, improvement in the economic growth outlook following initial fears about tariffs in April and expectations of interest rate cuts lifted shares of JPMorgan Chase and Morgan Stanley.
↑
In the IT sector, chipmaker Broadcom was a top contributor. Demand for artificial intelligence (AI)-related semiconductors remained quite strong. Expectations for cash flow and earnings continued to rise throughout the period under review.
↑
In the industrials sector, RTX was a meaningful contributor delivering robust performance along with solid earnings and optimistic guidance. Overall, contractors that make weapons and defense equipment rallied during the period with growth driven by rising global defense budgets.
Top detractors from absolute performance:
↓
The health care and materials sectors were the only detractors from absolute performance. The health care sector was particularly hard hit by an investment in UnitedHealth Group. The health insurer’s stock declined following several notable events, including the resignation of the company’s chief executive officer, the withdrawal of its 2025 outlook and an investigation by the U.S. Department of Justice into its billing practices. The Fund significantly reduced exposure over the period.
↓

The Linked benchmark replaced the Blended Benchmark effective March 1, 2025, as the Fund’s investment manager believes the new Linked Benchmark better reflects the composition of the Fund.
PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
Securitized products, along with the financials and consumer staples sectors, led absolute fixed income returns during the period. JBS was a top contributor within consumer staples, while Freddie Mac and Fannie Mae added value among securitized products.
↑
Among equities, returns were driven by the information technology (IT), industrials, and financials sectors. Cisco Systems and International Business Machines performed best within IT, while Boeing benefited returns within industrials.
↑
Overweight allocation and selection within the consumer staples, financials, and industrials sectors assisted relative fixed income returns. Meanwhile, equity returns benefited from underweight positioning and selection within consumer staples, in addition to stock selection within the industrials and energy sectors.
Top detractors from performance:
↓
Aside from U.S. Treasuries (USTs), no fixed income sectors or individual issuers meaningfully detracted from absolute returns.
↓
The communication services, materials, and consumer discretionary sectors hindered equity returns. In terms of individual issuers, UnitedHealth Group, Texas Instruments, and Edison International detracted.
↓
Relative fixed income returns were weakened by selection within USTs and underweight allocations to securitized products and government related securities. Further, stock selection among the health care and utilities sectors detracted from relative equity returns, as did an overweight allocation to materials companies.
Use of derivatives and the impact on performance:
The Fund utilized equity call and put options to sell and reduce positions and/or to initiate and add to positions, which contributed to performance.

HOW HAS THE FUND CHANGED?

Related disclosure regarding the risks involved with investing in issuers of lower-rated or high-yield debt securities (also known as “junk bonds”) was removed.
In addition, effective January 9, 2025, investments of $250,000 or more in Class A shares of the Fund will not be charged a sales charge, but will be subject to a 1% contingent deferred sales charge, if sold within 18 months of purchase.
