Portfolio holdings are based on total portfolio, and are subject to change at any time. Holdings are provided for informational purposes only and should not be construed as a recommendation to purchase or sell any security. Any negative allocations or allocations in excess of 100% are primarily due to unsettled trade activities.

Derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses and have a potentially large impact on Fund performance.

Distributions & Tax

Federal ID Number 04-3035821

Distributions per Share ($)

Year

Tax Information
Record Date	Ordinary Dividends Dividends paid by a fund that are derived from interest, dividends, net short-term capital gains and other types of ordinary income earned by the fund. For a fund that elects to pass through its foreign taxes paid (a non-cash item), a shareholder's allotted share of foreign taxes has been added to the “Ordinary Dividends” cash distributions received by the shareholder. If the fund passed through foreign taxes paid and later is refunded any portion of those taxes by a foreign tax authority, any interest paid to the fund on that refund is also required to be included in “Ordinary Dividends”.	Qualified Dividends The portion of a fund’s “Ordinary Dividends” that may be eligible for a reduced capital gain tax rate. To be eligible for the lower tax rates, certain holding periods apply and shareholders should consult their tax advisor to determine the amount eligible for the reduced rate. This amount represents both cash distributions and non-cash amounts, such as foreign taxes paid, that have been allocated to shareholders.	Capital Gain Distributions	Unrecaptured Section 1250 Gain	Non-Taxable Return Of Capital	Section 199a Dividends The portion of a fund’s “Ordinary Dividends” generated by a real estate investment trust or earned by a fund from its investments in real estate investment trusts, subject to limitations. Individual (non-corporate) shareholders may be entitled to a special deduction from gross income for “Section 199A Dividends” received from a fund. To qualify for this deduction certain holding periods apply and shareholders should consult their tax advisor.	Foreign Tax Paid	Exempt Interest Dividends	Interest on Tax Reclaim Refunds

Risks

All investments involve risks, including possible loss of principal. Fixed income securities involve interest rate, credit, inflation and reinvestment risks, and possible loss of principal. As interest rates rise, the value of fixed income securities falls. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on performance. An investor may be subject to the federal Alternative Minimum Tax, and state and local taxes may apply.

Important Information

The Closed-End Funds are not sold or distributed by Franklin Distributors, LLC. (FD, LLC) or any Franklin Templeton affiliated companies. Unlike open-end funds, shares are not continually offered. Like other public companies, closed-end funds have a one-time initial public offering, and once their shares are first issued, are generally bought and sold through non-affiliated broker/dealers and trade on nationally recognized stock exchanges. Share prices will fluctuate with market conditions and, at the time of sale, may be worth more or less than your original investment. Shares of exchange-traded closed-end funds may trade at a discount or premium to their original offering price, and often trade at a discount to their net asset value. Investment return, market price and net asset value will fluctuate with changes in market conditions. The Funds are subject to investment risks, including the possible loss of principal invested.

Footnotes

Net Asset Value (NAV) represents the value of a closed-end fund's underlying holdings per share. NAV is determined by dividing the total net assets of the fund by the number of shares outstanding. The fund calculates the NAV per share each business day normally coinciding with the close of trading on the New York Stock Exchange (NYSE).
Market Price, determined by supply and demand, is the price an investor purchases or sells the fund. The Market Price shown reflects the last trade on the listing exchange at the time that the fund's NAV is calculated.
Premium / Discount reflects the difference between the NAV and the Market Price of the fund, and represents the amount that the fund is trading above or below its NAV, expressed as a percentage of the NAV.
Distribution Rate is calculated by annualizing the most recent distribution amount paid, divided by the closing market price or NAV as of the date indicated. The Distribution Rate calculation includes income and return of capital, and excludes special distributions. The Distribution Rate is not guaranteed, subject to change, and is not a quotation of fund performance.

The information contained herein: (1) is proprietary to Morningstar and/or its content providers; (2) may not be copied or distributed and (3) is not warranted to be accurate, complete or timely. Neither Morningstar nor its content providers are responsible for any damages or losses arising from any use of this information.
Includes operating and other expenses.
Based on the Fund’s net assets of the common shares, as of the most recent Annual Report. See the fund’s Annual Report for information on the fund’s expenses.
The difference between total assets and net assets, if any, is due primarily to the Fund’s use of borrowings and other liabilities; net assets do not include borrowings. The Fund may employ leverage in the form of loans, preferred stock, reverse repurchase agreements and/or other instruments. When the Fund engages in transactions that have a leveraging effect on the Fund’s portfolio, the value of the Fund will be more volatile and all other risks will tend to be compounded.
Credit Quality is a measure of a bond issuer's ability to repay interest and principal in a timely manner. The credit ratings shown are based on each portfolio security's rating as provided by S&P Global Ratings, Moody's Investors Service and/or Fitch Ratings, Inc. and typically range from AAA (highest) to D (lowest), or an equivalent and/or similar rating. For this purpose, if two or more of the agencies have assigned differing ratings to a security, the lowest rating is used. Securities that are unrated by all three agencies are reflected as such. The credit quality of the investments in the portfolio does not apply to the stability or safety of the portfolio. The methodology used for the calculation of credit quality ratings displayed may differ from the methodology for monitoring investment limits, if applicable. Please note, the portfolio itself has not been rated by an independent rating agency.
Based on the fund’s Net Asset Value (NAV)
