PIMCO Municipal Income Funds III Letter to Shareholders

May 15, 2009

Dear Shareholder:

Please find enclosed the semi-annual report for the PIMCO Municipal Income Fund III, PIMCO California Municipal Income Fund III and PIMCO New York Municipal Income Fund III (the “Funds”) for the six months ended March 31, 2009.

The U.S. bond market provided positive returns during the fiscal six-month period, with municipal and high quality corporate bonds showing marked improvement as liquidity infusions improved credit market conditions and bolstered investor sentiment. In this environment, the Barclays Capital Municipal Bond Index returned a tax-advantaged 5.00% for the fiscal six-month period, outperforming the taxable, broad bond market return of 4.70% as represented by the Barclays Capital U.S. Aggregate Index. The Federal Reserve (the “Fed”) and U.S. Treasury Department moved aggressively during the fiscal six-month period to stave off bank failures and to inject liquidity into the banking system. The Fed reduced the Federal Funds rate three times during the fiscal six-month period, lowering the benchmark rate on loans between member banks from 2.00% to a target of 0% to 0.25%. In addition, the Fed pursued a policy of quantitative easing, buying securities from banks in order to add to the supply of cash available for lending.

On April 6, 2009, the Funds announced a change increasing the amount of Residual Interest Municipal Bonds (“RIBs”) in which a Fund may invest to 15% from 10% of their total assets. The change potentially allows the Funds to earn additional tax-free income. In addition, the use of RIBs, which results in a form of economic leverage, will allow the Funds to replace or increase leverage to some degree.

Please refer to the following pages for information on the Funds. If you have any questions regarding the information provided, we encourage you to contact your financial advisor or call the Funds’ shareholder servicing agent at (866) 298-8462. In addition, a wide range of information and resources is available on our Web site, www.allianzinvestors.com/closedendfunds.

Together with Allianz Global Investors Fund Management LLC, the Funds’ investment manager, and Pacific Investment Management Company LLC (“PIMCO”), the Funds’ sub-adviser, we thank you for investing with us.

We remain dedicated to serving your investment needs.

Sincerely,



Hans W. Kertess		Brian S. Shlissel

PIMCO Municipal Income Fund III Fund Insights
March 31, 2009 (unaudited)


•	For the fiscal six-month period ended March 31, 2009, PIMCO Municipal Income Fund III (“Muni III”) declined 23.73% on net asset value (“NAV”) and 18.27% on market price, compared with the decrease of 3.33% and rise of 3.94%, respectively, for the Lipper Analytical General Municipal Debt Funds (Leveraged) average.

•	High-quality municipal bond yields decreased across the curve for the fiscal six-month period ended March 31, 2009. The market began to rebound at the end of 2008 and continued into the first quarter of 2009.

•	Duration hedging strategies detracted from performance during the fiscal six-month period. Interest rates for Treasuries and London Inter-bank Offered Rate (“LIBOR”) swaps moved significantly lower due to a flight-to-quality and uncertain economic conditions. This move lower was larger than the move in high-quality municipal yields, causing municipals to underperform. However these rates moved higher off their lows in the first quarter of 2009, helping to recoup some of the negative performance for the hedge from the last quarter of 2008.

•	Municipal-to-Treasury yield ratios moved higher, remaining at very high levels compared to historical averages during the fiscal six-month period. The 10-year ratio increased to 118% and 30-year ratio increased to 135%.

•	Tobacco securitization sector holdings detracted from performance as municipal investors avoided all but the highest quality, most liquid issues during the period. The sector lost in excess of 15% during the fiscal six-month period due to this flight-to-quality.

•	Exposures to healthcare related municipals detracted from Muni III’s performance while exposure to the education sector contributed to performance during the fiscal six-month period.

•	Pre-refunded bond exposure contributed positively to performance as the sector performed well due to continued investor demand for the highest quality securities.

•	Exposure to zero coupon municipals detracted from performance as these securities underperformed coupon bonds during the period. The Barclays Capital Zero Coupon Index declined 1.46% for the fiscal six-month period.

•	The municipal yield curve saw a significant steepening during the fiscal six-month period as yields on the front end of the curve declined more than the longer end. The 15-, 20-, and 30-year maturity AAA General Obligation yields decreased by 105, 67, and 51 basis points, respectively while the two-year yield decreased by 155 basis points. Significant exposure in the long end of the yield curve detracted from Muni III’s performance as that area underperformed during the period.

•	Compared to long taxable sectors, long municipals underperformed due to the Treasury rally with the Barclays Capital Long Municipal Bond Index returning 1.63%% while the Barclays Capital U.S. Long Government/Credit and the Barclays Capital U.S. Long Treasury Indices returned 6.10% and 12.45%, respectively.

•	Municipal bond issuance continued to trend lower during the fourth quarter of 2008, remaining consistent with the previous year for the first quarter in 2009. During the fiscal six-month period, the overall municipal bond issuance was $35 billion, less than the same period in the prior year at $155 billion.

(1)

Past performance is no guarantee of future results. Total return is calculated by determining the percentage change in net asset value or market share price (as applicable) in the specified period. The calculation assumes that all income dividends and capital gain distributions have been reinvested. Total return does not reflect broker commissions or sales charges. Total return for a period of less than one year is not annualized. Total return for a period of more than one year represents the average annual total return.

Performance at market price will differ from its results at NAV. Although market price returns typically reflect investment results over time, during shorter periods returns at market price can also be influenced by factors such as changing views about the Fund, market conditions, supply and demand for the Fund’s shares, or changes in Fund distributions.

An investment in the Fund involves risk, including the loss of principal. Total return, market price, market yield and net asset value will fluctuate with changes in market conditions. This data is provided for information only and is not intended for trading purposes. Closed-end funds, unlike open-end funds, are not continuously offered. There is a onetime public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange. Net asset value is equal to total assets attributable to common shareholders less total liabilities divided by the number of common shares outstanding. Holdings are subject to change daily.


(2)	Market Price Yield is determined by dividing the annualized current monthly per share dividend payable to common shareholders by the market price per common share at March 31, 2009.

1. Organization and Significant Accounting Policies

PIMCO Municipal Income Fund III (“Municipal III”), PIMCO California Municipal Income Fund III (“California Municipal III”) and PIMCO New York Municipal Income Fund III (“New York Municipal III”), collectively referred to as the “Funds” or “PIMCO Municipal Income Funds III”, were organized as Massachusetts business trusts on August 20, 2002. Prior to commencing operations on October 31, 2002, the Funds had no operations other than matters relating to their organization and registration as non-diversified, closed-end management investment companies registered under the Investment Company Act of 1940 and the rules and regulations thereunder, as amended. Allianz Global Investors Fund Management LLC (the “Investment Manager”) serves as the investment manager and is an indirect, wholly-owned subsidiary of Allianz Global Investors of America L.P. (“Allianz Global”). Allianz Global is an indirect, wholly-owned subsidiary of Allianz SE, a publicly traded European insurance and financial services company. Each Fund has an unlimited amount of $0.00001 par value per share of common stock authorized.

Under normal market conditions, Municipal III invests substantially all of its assets in a portfolio of municipal bonds, the interest from which is exempt from federal income taxes. Under normal market conditions, California Municipal III invests substantially all of its assets in municipal bonds which pay interest that is exempt from federal and California state income taxes. Under normal market conditions, New York Municipal III invests substantially all of its assets in municipal bonds which pay interest that is exempt from federal, New York State and New York City income taxes. The Funds will generally seek to avoid investing in bonds generating interest income which could potentially subject individuals to alternative minimum tax. The issuers’ abilities to meet their obligations may be affected by economic and political developments in a specific state or region.

The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

In the normal course of business, the Funds enter into contracts that contain a variety of representations which provide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet been asserted. However, the Funds expect the risk of any loss to be remote.

The Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109” (the “Interpretation”). The Interpretation establishes for all entities, including pass-through entities such as the Funds, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. The Funds’ management has determined that its evaluation of the Interpretation has resulted in no material impact to the Funds’ financial statements at March 31, 2009. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

The following is a summary of significant accounting policies consistently followed by the Funds:

(a) Valuation of Investments

Portfolio securities and other financial instruments for which market quotations are readily available are stated at market value. Market value is generally determined on the basis of last reported sales prices, or if no sales are reported, on the basis of quotes obtained from a quotation reporting system, established market makers, or independent pricing services.

Portfolio securities and other financial instruments for which market quotations are not readily available or for which a development/event occurs that may significantly impact the value of a security, are fair-valued, in good faith, pursuant to procedures established by the Board of Trustees, or persons acting at their discretion pursuant to procedures established by the Board of Trustees. The Funds’ investments are valued daily using prices supplied by an independent pricing service or dealer quotations, or by using the last sale price on the exchange that is the primary market for such securities, or the last quoted mean price for those securities for which the over-the-counter market is the primary market or for listed securities in which there were no sales. Independent pricing services use information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Exchange-traded options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Securities purchased on a when-issued or delayed-delivery basis are marked to market daily until settlement at the forward settlement value. Short-term securities maturing in 60 days or less are valued at amortized cost, if their original term to maturity was 60 days or less, or by amortizing their value on the 61st day prior to maturity, if the original term to maturity exceeded 60 days.

PIMCO Municipal Income Funds III Semi-Annual Report 29

PIMCO Municipal Income Funds III Notes to Financial Statements
March 31, 2009 (unaudited)

1. Organization and Significant Accounting Policies (continued)

The prices used by the Funds to value securities may differ from the value that would be realized if the securities were sold and these differences could be material to the financial statements. Each Fund’s net asset value is normally determined as of the close of regular trading (normally, 4:00 p.m. Eastern time) on the New York Stock Exchange (“NYSE”) on each day the NYSE is open for business.

(b) Fair Value Measurement

Effective October 1, 2008, the Funds adopted FASB Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosure about the use of the fair value measurements. Under this standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants. The three levels of the fair value hierarchy under SFAS 157 are described below:


•	Level 1 – quoted prices in active markets for identical investments that the Funds have the ability to access

•	Level 2 – valuations based on other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.) or quotes from inactive exchanges

•	Level 3 – valuations based on significant unobservable inputs (including the Funds’ own assumptions in determining the fair value of investments)

The valuation techniques used by the Funds to measure fair value during the six months ended March 31, 2009 maximized the use of observable inputs and minimized the use of unobservable inputs.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of March 31, 2009 in valuing each Fund’s investments carried at value:


	Municipal Income III		California Municipal III		New York Municipal III
	Investments in		Investments in		Investments in
Valuation Inputs	Securities		Securities		Securities


Level 1 – Quoted Prices		$—		$—		$—
Level 2 – Other Significant Observable Inputs		506,749,768		320,290,712		81,852,006
Level 3 – Significant Unobservable Inputs		—		—		—


Total		$506,749,768		$320,290,712		$81,852,006

A roll forward of fair value measurements using significant unobservable inputs (Level 3) as of March 31, 2009, were as follows:

Municipal Income III:


	Investments in
	Securities


Beginning balance, 10/01/08		$149,999

PIMCO Municipal Income Funds III Notes to Financial Statements

1. Organization and Significant Accounting Policies (continued)

In April 2009, the FASB issued FASB Staff Position No. 157-4. “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly” (“FSP 157-4”). FSP 157-4 provides additional guidance for estimating fair value in accordance with SFAS 157, when the volume and level of activity for the asset or liability have significantly decreased as well as guidance on identifying circumstances that indicate a transaction is not orderly. FSP 157-4 is effective for fiscal years and interim periods ending after June 15, 2009. The Funds’ management is currently evaluating the impact the adoption of FSP 157-4 will have on the Funds’ financial statement disclosures.

(c) Disclosures about Credit Derivatives

The Funds have adopted FASB Staff Positions No. 133-1 and FIN 45-4 “Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FAS Interpretation No. 45; and Clarification of the Effective Date of FASB Statement No. 161” (“FSP”), which required enhanced transparency of the effect of credit derivatives and guarantees on an issuer’s financial position, financial performance and cash flows. FSP is effective for reporting periods after November 15, 2008. FSP applies to certain credit derivatives, hybrid instruments that have embedded credit derivatives (for example, credit-linked notes), and certain guarantees and it requires additional disclosures regarding credit derivatives with sold protection. Fund management has determined that FSP has no material impact on the Funds’ financial statements.

See also “Swap Agreements” – Note 1(h) for description of the nature of each credit derivative, maximum potential amount of future payments (undiscounted) the Fund could be required to make under the credit derivatives with sold protection and fair value of each credit derivative at March 31, 2009. Potential losses related to hybrid instruments that have embedded credit derivatives are limited to the initial cost of investments.

In March 2008, FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). was issued and is effective for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about a fund’s derivative and hedging activities. Fund management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund’s financial statement disclosures.

(d) Investment Transactions and Investment Income

Investment transactions are accounted for on the trade date. Securities purchased and sold on a when-issued or delayed-delivery basis may be settled a month or more after the trade date. Realized gains and losses on investments are determined on an identified cost basis. Interest income adjusted for the accretion of discounts and amortization of premiums is recorded on an accrual basis. Discounts or premiums on debt securities purchased are accreted or amortized, respectively, to interest income over the lives of the respective securities using the effective interest method.

(e) Federal Income Taxes

The Funds intend to distribute all of their taxable income and to comply with the other requirements of the U.S. Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, no provision for U.S. federal income taxes is required.

(f) Dividends and Distributions — Common Stock

The Funds declare dividends from net investment income monthly to common shareholders. Distributions of net realized capital gains, if any, are paid at least annually. The Funds record dividends and distributions to their shareholders on the ex-dividend date. The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from generally accepted accounting principles. These “book-tax” differences are considered either temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal income tax treatment; temporary differences do not require reclassification. To the extent dividends and/or distributions exceed current and accumulated earnings and profits for federal income tax purposes; they are reported as dividends and/or distributions of paid-in-capital in excess of par.

(g) Futures Contracts

The Funds may enter into futures contracts. A futures contract is an agreement between two parties to buy and sell a financial instrument at a set price on a future date. Upon entering into such a contract, the Funds are required to pledge to the broker an amount of cash or securities equal to the minimum “initial margin” requirements of the exchange. Pursuant to the contracts, the Funds agree to receive from or pay to the broker an amount of cash or securities equal to the daily fluctuation in the value of the contracts. Such receipts or payments are known as “variation margin” and are recorded by the Funds as unrealized appreciation or depreciation. When the contracts are closed, the Funds record a realized gain or loss equal to the difference between the value of the contracts at the time they were opened and the value at the time

3.31.09

PIMCO Municipal Income Funds III Semi-Annual Report 31

PIMCO Municipal Income Funds III Notes to Financial Statements
March 31, 2009 (unaudited)

1. Organization and Significant Accounting Policies (continued)

they were closed. Any unrealized appreciation or depreciation recorded is simultaneously reversed. The use of futures transactions involves the risk of an imperfect correlation in the movements in the price of futures contracts, interest rates and the underlying hedged assets, and the possible inability of counterparties to meet the terms of their contracts.

(h) Swap Agreements

The Funds may enter into in swap agreements. Swap agreements are privately negotiated agreements between the Funds and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. The Funds may enter into credit default, cross- currency, interest rate, total return, variance and other forms of swap agreements in order to manage their exposure to credit, currency and interest rate risk. In connection with these agreements, securities may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Payments received or made at the beginning of the measurement period are reflected as such on the Statements of Assets and Liabilities and represent payments made or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). These upfront payments are recorded as realized gains or losses on the Statements of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain or loss on the Statements of Operations. Net periodic payments received or paid by the Funds are included as part of realized gains or losses on the Statement of Operations.

Entering into these agreements involves, to varying degrees, elements of credit, legal market and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks include the possibility that there will be no liquid market for these agreements, that the counterparties to the agreements may default on their obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates.

Interest Rate Swap Agreements – Interest rate swap agreements involve the exchange by the Funds with another party of their respective commitments to pay or receive interest with respect to the notional amount of principal. Certain forms of interest rate swap agreements may include: (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”, (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”, (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels, (iv) callable interest rate swaps, under which the counterparty may terminate the swap transaction in whole at zero cost by a predetermined date and time prior to the maturity date, (v) spreadlocks, which allow the interest rate swap users to lock in the forward differential (or spread) between the interest rate swap rate and a specified benchmark, or (vi) basis swap, under which two parties can exchange variable interest rates based on different money markets.

(i) Reverse Repurchase Agreements

The Funds may enter into reverse repurchase agreements. In a reverse repurchase agreement, the Funds sell securities to a bank or broker-dealer and agree to repurchase the securities at a mutually agreed date and price. Generally, the effect of such a transaction is that the Funds can recover and reinvest all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement and still be entitled to the returns associated with those portfolio securities. Such transactions are advantageous if the interest cost to the Funds of the reverse repurchase transaction is less than the returns it obtains on investments purchased with the cash. Unless the Funds covers their positions in reverse repurchase agreements (by segregating liquid assets at least equal in amount to the forward purchase commitment), their obligations under the agreements will be subject to the Funds’ limitations on borrowings. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Fund are obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Funds’ use of the proceeds of the agreement may be restricted pending determination by the other party, or its trustee or receiver, whether to enforce the Funds’ obligation to repurchase the securities.

(j) Inverse Floating Rate Transactions — Residual Interest Municipal Bonds (“RIBs”) / Residual Interest Tax Exempt Bonds (“RITEs”)

The Funds may invest in RIBs and RITEs, (“Inverse Floaters”) whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. In inverse floating rate transactions, the Funds sell a fixed rate municipal bond (“Fixed Rate Bond”) to a broker who places the Fixed Rate Bond in a special purpose trust (“Trust”) from

which floating rate bonds (“Floating Rate Notes”) and Inverse Floaters are issued. The Funds simultaneously or within a short period of time purchase the Inverse Floaters from the broker. The Inverse Floaters held by the Funds provide the Funds with the right to: (1) cause the holders of the Floating Rate Notes to tender their notes at par, and (2) cause the broker to transfer the Fixed-Rate Bond held by the Trust to the Funds, thereby collapsing the Trust. Pursuant to Statement of Financial Accounting Standards No. 140 (“FASB Statement No. 140”), the Funds account for the transaction described above as a secured borrowing by including the Fixed Rate Bond in their Schedules of Investments, and account for the Floating Rate Notes as a liability under the caption “Payable for floating rate notes” in the Funds’ Statements of Assets and Liabilities. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option to tender their notes to the broker for redemption at par at each reset date.

The Funds may also invest in Inverse Floaters without transferring a fixed rate municipal bond into a special purpose trust, which are not accounted for as secured borrowings.

Inverse Floaters are created by dividing the income stream provided by the underlying bonds to create two securities, one short-term and one long-term. The interest rate on the short-term component is reset by an index or auction process typically every 7 to 35 days. After income is paid on the short-term securities at current rates, the residual income from the underlying bond(s) goes to the long-term securities. Therefore, rising short-term rates result in lower income for the long-term component and vice versa. The longer-term bonds may be more volatile and less liquid than other municipal bonds of comparable maturity. Investments in Inverse Floaters typically will involve greater risk than in an investment in Fixed Rate Bonds. The Funds may also invest in Inverse Floaters for the purpose of increasing leverage.

The Funds’ restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes pursuant to FASB Statement No. 140. Inverse Floaters held by the Funds are exempt from registration under Rule 144A of the Securities Act of 1933.

(k) When-Issued/Delayed-Delivery Transactions

The Funds may purchase or sell securities on a when-issued or delayed-delivery basis. The transactions involve a commitment to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When delayed-delivery purchases are outstanding, the Funds will set aside and maintain until the settlement date in a designated account, liquid assets in an amount sufficient to meet the purchase price. When purchasing a security on a delayed-delivery basis, the Funds assume the rights and risks of ownership of the security, including the risk of price and yield fluctuations. Consequently, such fluctuations are taken into account when determining the net asset value. The Funds may dispose of or renegotiate a delayed-delivery transaction after it is entered into, and may sell when-issued securities before they are delivered, which may result in a realized gain or loss. When a security on a delayed-delivery basis is sold, the Funds do not participate in future gains and losses with respect to the security.

(l) Custody Credits on Cash Balances

The Funds benefit from an expense offset arrangement with their custodian bank whereby uninvested cash balances earn credits which reduce monthly custodian and accounting agent expenses. Had these cash balances been invested in income-producing securities, they would have generated income for the Funds.

(m) Interest Expense

Interest expense relates to the Funds’ liability in connection with floating rate notes held by third parties in conjunction with Inverse Floater transactions. Interest expense is recorded as it is incurred.

2. Investment Manager/Sub-Adviser

The Funds have Investment Management Agreements (collectively the “Agreements”) with the Investment Manager. Subject to the supervision of each Fund’s Board of Trustees, the Investment Manager is responsible for managing, either directly or through others selected by it, each Fund’s investment activities, business affairs and administrative matters. Pursuant to the Agreements, the Investment Manager receives an annual fee, payable on a monthly basis, at an annual rate of 0.65% of each Fund’s average daily net assets, inclusive of net assets attributable to any preferred shares that may be outstanding. In order to reduce each Fund’s expenses, the Investment Manager has contractually agreed to waive a portion of its investment management fees for each Fund at the annual rate of 0.10% of each Fund’s average daily net assets, inclusive of net assets attributable to any preferred shares that may be outstanding through October 31, 2008. On November 1, 2008, the contractual fee waiver was reduced to 0.05% of each Funds’ average daily net assets, including net assets attributable to any preferred shares that may be outstanding through October 31, 2009. For the fiscal year

2. Investment Manager/Sub-Adviser (continued)

ended March 31, 2009, each Fund paid investment management fees at an annualized effective rate of 0.59% of each Fund’s average daily net assets inclusive of net assets attributable to any preferred shares that may be outstanding.

The Investment Manager has retained its affiliate, Pacific Investment Management Company LLC (the “Sub-Adviser”), to manage each Fund’s investments. Subject to the supervision of the Investment Manager, the Sub-Adviser is responsible for making all the Funds’ investment decisions. The Investment Manager, not the Funds, pays a portion of the fees it receives to the Sub-Adviser in return for its services.

5.	Auction-Rate Preferred Shares (continued)

For the six months ended March 31, 2009, the annualized dividend rates for each Fund ranged from:


	High	Low	At March 31, 2009


Municipal III:
Series A	8.499%	0.640%	0.685%
Series B	8.652%	0.640%	0.746%
Series C	12.261%	0.625%	0.746%
Series D	11.728%	0.594%	0.746%

California Municipal III:

Series B	11.728%	0.594%	0.746%
New York Municipal III:
Series A	8.499%	0.685%	0.685%

The Funds are subject to certain limitations and restrictions while Preferred Shares are outstanding. Failure to comply with these limitations and restrictions could preclude the Funds from declaring any dividends or distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of Preferred Shares at their liquidation value.

Preferred shareholders, who are entitled to one vote per share, generally vote with the common stock but vote separately as a class to elect two Trustees and on any matters affecting the rights of the preferred shareholders.

Since mid-February 2008, holders of auction-rate preferred shares (“ARPS”) issued by the Funds have been directly impacted by an unprecedented lack of liquidity, which has similarly affected ARPS holders in many of the nation’s closed-end funds. Since then, regularly scheduled auctions for ARPS issued by the Funds have consistently “failed” because of insufficient demand (bids to buy shares) to meet the supply (shares offered for sale) at each auction. In a failed auction, ARPS holders cannot sell all, and may not be able to sell any, of their shares tendered for sale. While repeated auction failures have affected the liquidity for ARPS, they do not constitute a default or automatically alter the credit quality of the ARPS, and ARPS holders have continued to receive dividends at the defined “maximum rate” as the higher of the 30-day “AA” Composite Commercial Paper Rate multiplied by 110% or the Taxable Equivalent of the Short-Term Municipal Obligations Rate-defined as 90% of the quotient of (A) the per annum rate expressed on an interest equivalent basis equal to the Kenny S&P 30-day High Grade Index divided by (B) 1.00 minus the Marginal Tax Rate (expressed as a decimal) multiplied by 110% (which is a function of short-term interest rates and typically higher than the rate that would have otherwise been set through a successful auction).

These developments with respect to ARPS have not affected the management or investment policies of the Funds, and the Funds’ outstanding common shares continue to trade on the NYSE without any change. If the Funds’ ARPS auctions continue to fail and the “maximum rate” payable on the ARPS rises as a result of changes in short-term interest rates, returns for the Funds’ common shareholders could be adversely affected.

During the six months ended March 31, 2009, the Funds redeemed a portion of their ARPS. The redemptions were intended to increase asset coverage for each Fund’s ARPS above the 200% Level (subject to future market conditions), permitting the Funds to pay previously declared common share dividends and: to declare and pay future common share dividends. The Funds redeemed, at the full liquidation preference of $25,000 per share plus accumulated but unpaid dividends, up to each series respective dates of redemption.

6.	Subsequent Common Dividend Declarations

On April 1, 2009, the following dividends were declared to common shareholders payable May 1, 2009 to shareholders of record on April 13, 2009:


Municipal III		$0.07 per common share
California Municipal III		$0.06 per common share
New York Municipal III		$0.0525 per common share

On May 1, 2009, the following dividends were declared to common shareholders payable June 1, 2009 to shareholders of record on May 11, 2009:


Municipal III		$0.07 per common share
California Municipal III		$0.06 per common share
New York Municipal III		$0.0525 per common share


7.	Legal Proceedings

In June and September 2004, the Investment Manager and certain of its affiliates (including PEA Capital LLC (“PEA”), Allianz Global Investors Distributors LLC and Allianz Global Investors of America, L.P.), agreed to settle, without admitting or denying the allegations, claims brought by the SEC and the New Jersey Attorney General alleging violations of federal and state securities laws with respect to certain open-end funds for which the Investment Manager serves as investment adviser. The settlements related to an alleged “market timing” arrangement in certain open-end funds formerly sub-advised by PEA. The Investment Manager and its affiliates agreed to pay a total of $68 million to settle the claims. In addition to monetary payments, the settling parties agreed to undertake certain corporate governance, compliance and disclosure reforms related to market timing and consented to cease and desist orders and censures. Subsequent to these events, PEA deregistered as an investment adviser and dissolved. None of the settlements alleged that any inappropriate activity took place with respect to the Funds.

Since February 2004, the Investment Manager, the Sub-Adviser and certain of their affiliates and their employees have been named as defendants in a number of pending lawsuits concerning “market timing” which allege the same or similar conduct underlying the regulatory settlements discussed above. The market timing lawsuits have been consolidated in a multi-district litigation proceeding in the U.S. District Court for the District of Maryland. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against the Investment Manager, the Sub-Adviser, or their affiliates or related injunctions.

The Investment Manager and the Sub-Adviser believe that these matters are not likely to have a material adverse effect on the Funds or on their ability to perform their respective investment advisory activities relating to the Funds.

The foregoing speaks only as of the date hereof.


8	Portfolio Manager Change

Effective December 11, 2008, Mr. John Cummings assumed primary responsibility for the day-to-day portfolio management of each of the Funds. Mr. Cummings is an Executive Vice President at PIMCO. He joined PIMCO in 2002, and previously was at Goldman Sachs as an institutional trader, responsible for a number of municipal sectors including industrials, airlines, utilities, healthcare and high-yield. Mr. Cummings has over 20 years of investment experience and earned an MBA and undergraduate degree from Rutgers University.


9.	Subsequent Event-Change to the Funds’ Investment Policies and Related Risks

Effective April 6, 2009, each Fund’s investment policy has been revised to increase the amount of Residual Interest Municipal Bonds (“RIBs”) in which each Fund may invest to 15% from 10% of its total assets. The Board of Trustees approved the changes based on the recommendation of the Funds’ Investment Manager and Sub-Adviser that this limit increase in RIBs would be in the best interest of the Funds and the Funds’ shareholders. In addition, this change potentially allows the Funds to earn additional tax-free income. In addition, the use of RIBs, which results in a form of economic leverage, will allow the Funds to replace or increase leverage to some degree.

March 31, 2009 (unaudited)


9.	Subsequent Event Change to the Funds’ Investment Policies and Related Risks (continued)

In addition to general market risks, the Funds’ investments in RIBs may involve greater risk and volatility than an investment in a fixed rate bond, and the value of RIBs may decrease significantly when market interest rates increase. RIBs have varying degrees of liquidity, and the market for these securities may be volatile. These securities tend to underperform the market for fixed rate bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, RIBs typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Trusts in which RIBS may be held could be terminated due to market, credit or other events beyond the Funds’ control, which could require a Fund to reduce leverage and dispose of portfolio investments at inopportune times and prices.

(1)		Total investment return is calculated assuming a purchase of a share of common stock at the current market price on the first day of each period and a sale of a share of common stock at the current market price on the last day of each period reported. Dividends and distributions are assumed, for purposes of this calculation, to be reinvested at prices obtained under the Fund’s dividend reinvestment plan. Total investment return does not reflect brokerage commissions or sales charges. Total investment return for a period of less than one year is not annualized.

(2)		Calculated on the basis of income and expenses applicable to both common and preferred shares relative to the average net assets of common shareholders.

(3)		Inclusive of expenses offset by custody credits earned on cash balances at the custodian bank. (See Note 1(l) in Notes to Financial Statements).

(4)		Interest expense relates to the liability for floating rate notes issued in connection with inverse floater transactions and reverse repurchase agreement transactions.

(5)		During the periods indicated above, the Investment Manager waived a portion of its investment management fee. (See Note 2 in Notes to Financial Statements). The effect of such waiver relative to the average net assets of common shareholders was 0.11% (annualized), 0.17%, 0.24%, 0.24%, 0.24% and 0.24%, for the six months ended March 31, 2009, the years ended September 30, 2008, September 30, 2007, September 30, 2006, September 30, 2005 and September 30, 2004, respectively.
