Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 34 in the Fund's Prospectus and under “Buying and Selling Shares” on page 55 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific intermediaries is set forth in Appendix A – Intermediary Sales Charge Discounts and Waivers to the Fund’s prospectus.

Please note that the tables and examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or Advisor Class shares.

Shareholder Fees (fees paid directly from your investment)

	Class A	Class C	Class R	Class R6	Advisor Class
Maximum Sales Charge (Load) Imposed on Purchases (as percentage of offering price)	4.25%	None	None	None	None
Maximum Deferred Sales Charge (Load) (as percentage of the lower of original purchase price or sale proceeds)	None¹	1.00%	None	None	None

1. There is a 0.75% contingent deferred sales charge that applies to investments of $1 million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

	Class A	Class C	Class R	Class R6	Advisor Class
Management fees	0.45%	0.45%	0.45%	0.45%	0.45%
Distribution and service (12b-1) fees	0.15%	0.65%	0.50%	None	None
Other expenses	0.18%	0.18%	0.18%	0.02%	0.18%
Acquired fund fees and expenses¹	0.01%	0.01%	0.01%	0.01%	0.01%
Total annual Fund operating expenses¹	0.79%	1.29%	1.14%	0.48%	0.64%
Fee waiver and/or expense reimbursement²	-0.01%	-0.01%	-0.01%	-0.01%	-0.01%
Total annual Fund operating expenses after fee waiver and/or expense reimbursement^1,²	0.78%	1.28%	1.13%	0.47%	0.63%

1. Total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights, which reflect the operating expenses of the Fund and do not include acquired fund fees and expenses.

2. The investment manager has contractually agreed in advance to reduce its fee as a result of the Fund's investment in a Franklin Templeton money fund (acquired fund) for the next 12-month period. Contractual fee waiver and/or expense reimbursement agreements may not be changed or terminated during the time periods set forth above.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management as described above for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A	$ 501	$ 666	$ 844	$ 1,361
Class C	$ 230	$ 408	$ 707	$ 1,556
Class R	$ 115	$ 361	$ 627	$ 1,386
Class R6	$ 48	$ 153	$ 268	$ 603
Advisor Class	$ 64	$ 204	$ 356	$ 798
If you do not sell your shares:
Class C	$ 130	$ 408	$ 707	$ 1,556

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 18.58% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests predominantly in high yield, lower-rated debt securities. Lower-rated securities generally pay higher yields than more highly rated securities to compensate investors for the higher risk. These securities include bonds, notes, debentures, convertible securities and senior and subordinated debt securities. The Fund may also invest in preferred stock.

The Fund may invest up to 100% of its total assets in debt securities that are rated below investment grade, also known as “junk bonds.” Investment grade debt securities are rated in one of the top four ratings categories by at least one independent rating agency such as Standard & Poor’s (S&P^®) and Moody’s Investors Service (Moody’s). The Fund may buy both rated and unrated debt securities, including securities rated below B by Moody's or S&P^{^®}(or deemed comparable by the Fund's investment manager). The Fund may also invest in defaulted debt securities and in securities issued by issuers in any foreign country, developed or developing. Foreign securities held by the Fund generally will be denominated in U.S. dollars and traded on U.S. markets.

The Fund's investment manager is a research driven, fundamental investor that relies on a team of analysts to provide in-depth industry expertise and uses both qualitative and quantitative analysis to evaluate issuers. As a "bottom-up" investor, the investment manager focuses primarily on individual securities. The investment manager also considers sectors when choosing investments and, from time to time, may have significant investments in certain sectors.

In selecting securities for the Fund’s investment portfolio, the investment manager does not rely principally on the ratings assigned by rating agencies, but performs its own independent investment analysis to evaluate the creditworthiness of the issuer. The investment manager considers a variety of factors, including the issuer’s experience and managerial strength, its sensitivity to economic conditions, and its current and prospective financial condition.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Credit An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.

High-Yield Debt Securities Issuers of lower-rated or “high-yield” debt securities (also known as “junk bonds”) are not as strong financially as those issuing higher credit quality debt securities. High-yield debt securities are generally considered predominantly speculative by the applicable rating agencies as their issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

Income Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

Liquidity From time to time, the trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and will also generally lower the value of a security or other investments. Market prices for such securities or other investments may be volatile.

Interest Rate When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand of bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

Foreign Securities Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies. The risks of foreign investments may be greater in developing or emerging market countries.

Focus To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

Prepayment Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. A security's market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Management The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at franklintempleton.com or by calling (800) DIAL BEN/342-5236.

The secondary index in the table below shows how the Fund's performance compares with the returns of an index of funds with similar investment objectives as the Fund.
