10.31.10 ï PIMCO Municipal Income Funds Semi-Annual Report 1

Dear Shareholder:


Municipal bonds rose in price during the fiscal six-month period ended October 31, 2010, as the U.S. economy continued to recover from the recession that ended in mid-2009. But the recovery has slowed from its pace of a year ago, and there are legitimate concerns about ongoing fiscal woes in many states and the impact this could have on the municipal bond market.		Hans W. Kertess Chairman


Six Months In Review For the fiscal six-month period ended October 31, 2010: • PIMCO Municipal Income Fund rose 8.32% on net asset value (“NAV”) and 7.96 % on market price. • PIMCO California Municipal Fund rose 8.20% on NAV and 8.84% on market price. • PIMCO New York Municipal Income Fund rose 7.16% NAV and 3.63% on market price.		Brian S. Shlissel President & CEO

After growing at an annual rate of 5.0% during the fourth quarter of 2009, the U.S. economy slowed considerably in 2010: 3.7% in the first quarter, 1.7% in the second and 2.5% in the third. As it deaccelerated, the Federal Reserve (“the Fed”) decided to resume its purchase of U.S. Treasury bonds. The goal of this “quantitative easing II” was to lower interest rates and boost economic activity. But the Fed’s purchase program focused on short-to-medium term Treasuries and generally excluded bonds with longer maturities. Thus, long-term Treasuries fell in price. Since municipal bonds tend to move in tandem with Treasuries, the prices of longer-term municipal securities also fell.

The Road Ahead

Concerns about the fiscal situation at the state and local level – and the impact this could have on municipal bonds – are clearly justified. According to the non-partisan Center on Budget and Policy Priorities, for 2011 46 states face budget shortfalls. In 18 of these states, the default represents more than 20% of planned expenditures.

2 PIMCO Municipal Income Funds Semi-Annual Report ï 10.31.10

As the recession neared bottom in early 2009, the Obama administration unveiled its $787 billion stimulus plan to boost the economy. Part of the stimulus package was the “Build America Bonds” (“BAB”) program. The BAB program was designed to help cash-strapped states and cities cope with the downturn by subsidizing borrowing costs for important municipal projects. But after Republicans reclaimed the House of Representatives and made sizable gains in the Senate, it became clear that the BAB program – due to expire on December 31, 2010 – would not be extended. Realizing this, many state and city governments flooded the municipal market with BABs. So much supply came onto market that it could not be absorbed, thus putting sudden, downward pressure on municipal bond prices.

The afore-mentioned quantitative easing strategy has hurt many municipal bonds as well. The Fed’s purchase of Treasury securities generally excludes bonds with longer maturities. This in turn has led to lower prices for longer-term municipal bond prices, which correlate somewhat closely to Treasuries. As a result, investor interest in long-term municipal bonds has waned. As calendar year 2010 comes to an end, we anticipate a large supply of tax-exempt municipal bonds to come to market, which may have an adverse effect on prices.

The tax deal compromise between President Obama and Congress has also hurt municipal bond prices. The compromise preserves the Bush-era tax cuts for upper income earners, thus making tax-exempt securities somewhat less attractive. The bill’s provisions cover calendar years 2011 and 2012 and are due to expire on December 31, 2012.

All that aside, we believe these developments should be largely short-term in nature. From a longer perspective, the expectation of higher taxes at all levels of government and historically low default rates should continue to make municipal securities compelling investments for many people.

PIMCO Municipal Income Funds Insights
October 31, 2010 (unaudited)

For the fiscal six-month period ended October 31, 2010, PIMCO Municipal Income Fund rose 8.32% on NAV and 7.96 % on market price. PIMCO California Municipal Fund rose 8.20% on NAV and 8.84% on market price. PIMCO New York Municipal Income Fund rose 7.16% NAV and 3.63% on market price.

The high-quality segment of the municipal bond market produced positive returns during the reporting period, as yields moved lower across the curve. On longer maturities, municipal bonds underperformed the stronger taxable bond market, with the Barclays Capital Long Municipal Bond Index returning 4.70% while the Barclays Capital Long Government/Credit index returned 9.05%, and the Barclays Capital Long U.S. Treasury index returned 11%. The Barclays Capital Zero Coupon Municipal Bond Index returned 5.27% for the reporting period. Municipal to Treasury yield ratios – a measure of the relative attractiveness of municipal and Treasury bonds – ended higher as Treasuries outperformed municipals. The 10-year ratio – a measure of the relative attractiveness of Treasuries and municipal bonds – increased to 97% and the 30-year ratio decreased to 97%.

Not all of the Funds’ positions were beneficial for returns. The Funds’ holdings in higher-quality credits detracted from performance, as lower credit-quality securities outperformed the high-grade market.

PIMCO Municipal Income Fund

Holdings in the health care sector added to the Fund’s returns, as the sector significantly outperformed most other sectors of the municipal bond market. The Fund also benefited from its interest rate positioning during the reporting period. Exposure to longer-maturity zero coupon and nominal municipal bonds allowed the Fund to participate in the widespread decline in yields at the longer end of the municipal market. The Fund also gained from its positions in corporate-backed municipals, which significantly outperformed the general municipal market during the period.

Amid generally declining yields, the municipal yield curve steepened slightly during the reporting period, following the lead of the Treasury market. Over the period, 30-year maturity AAA General Obligation (“GO”) yields decreased by 18 basis points, while 2-year yields decreased by 24 basis points.

PIMCO California Municipal Income Fund

California municipal bonds outperformed the national index, with the Barclays Capital California Municipal Bond Index returning 4.28% versus 3.95% for the Barclays Capital Municipal Bond index over the period. In spite of this outperformance, continued volatility is expected as the state continues to struggle through their budget process, even with the budget balance agreement. Long California municipal bonds outperformed their peers in the national index, returning 5.16% versus the Barclays Capital Long Municipal Bond Index gain of 4.70% cited above. The California municipal curve steepened even more significantly than the national markets during the reporting period, with 30-year yields decreased by 17 basis point while 2-year yields decreased by 32 basis points.

Holdings in the health care sector contributed to the Fund’s returns, as the sector significantly outperformed the rest of the municipal bond market. Exposure to longer-maturity nominal and zero coupon municipals allowed the Fund to participate in the widespread decline in yields at the longer end of the municipal market. The Fund also gained from its positions in corporate-backed municipals, which significantly outperformed the general municipal market.

PIMCO New York Municipal Income Fund

Amid generally declining yields, the New York municipal yield curve steepened, following the lead of the national municipal and Treasury markets. During the period, 30-year maturity yields decreased by 20 basis points while 2-year yields decreased by 25 basis points. New York municipals, as measured by the Barclays Capital New York Municipal Bond Index, returned 3.79% for the period, slightly trailing the national market’s 3.95% gain, as measured by the Barclays Capital Municipal Bond Index. The long-maturity segment of the New York market also underperformed the long segment of the national municipal bond market, returning 4.30% versus the Barclays Capital Long Municipal Bond Index gain of 4.70% cited above.

Holdings in the health care sector contributed to the Fund’s returns, as the sector outperformed most sectors of the municipal bond market. The Fund also gained from its positions in transportation municipals, which outperformed the general municipal market. Exposure to corporate-backed municipals contributed significantly to returns. Exposure to longer-maturity nominal and zero coupon municipal bonds in New York allowed the Fund to participate in the decline in yields at the longer end of the New York municipal market.

(1) Past performance is no guarantee of future results. Total return is calculated by determining the percentage change in NAV or market price (as applicable) in the specified period. The calculation assumes that all income dividends, and capital gain distributions, if any, 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 Funds, market conditions, supply and demand for each Fund’s shares, or changes in each dividends.

An investment in each Fund involves risk, including the loss of principal. Total return, market price, market yield and NAV asset will fluctuate with changes in market conditions. This data is provided for information purposes 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 traded in the open market through a stock exchange. NAV 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 (comprised of net investment income) payable to common shareholders by the market price per share at October 31, 2010.

1. Organization and Significant Accounting Policies

PIMCO Municipal Income Fund (”Municipal”), PIMCO California Municipal Income Fund (”California Municipal”) and PIMCO New York Municipal Income Fund (”New York Municipal”), each a “Fund” and collectively referred to as the ”Funds” or ”PIMCO Municipal Income Funds”, were organized as Massachusetts business trusts on May 10, 2001. Prior to commencing operations on June 29, 2001, 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 no par value per share of common shares authorized.

Under normal market conditions, Municipal 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 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 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. There is no guarantee that the Funds will meet their stated objectives.

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 Funds’ 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 that 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 occurred.

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 mean between the last quoted bid and ask price. 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. Securities purchased on a when-issued basis are marked to market daily until settlement at the forward settlement date. 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.

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 Funds’ 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 Measurements

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 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

PIMCO Municipal Income Funds Notes to Financial Statements
October 31, 2010 (unaudited)

1. Organization and Significant Accounting Policies (continued)


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

An investment asset’s or liability’s level within the fair value hierarchy is based on the lowest level input, individually or in aggregate, that is significant to fair value measurement. The objective of fair value measurement remains the same even when there is a significant decrease in the volume and level of activity for an asset or liability and regardless of the valuation technique used.

The valuation techniques used by the Funds to measure fair value during the six months ended October 31, 2010 maximized the use of observable inputs and minimized the use of unobservable inputs.

The inputs or methodology used for valuing securities is not necessarily an indication of the risk associated with investing in those securities. The following are certain inputs and techniques that the Funds generally use to evaluate how to classify each major category of assets and liabilities in accordance with Generally Accepted Accounting Principles (“GAAP”).

Municipal Bonds and Variable Rate Notes – Municipal bonds and variable rate notes are valued by independent pricing services based on pricing models that take into account, among other factors, information received from market makers and broker-dealers, current trades, bid-want lists, offerings, market movements, the callability of the bond, state of issuance, benchmark yield curves, and bond insurance. To the extent that these inputs are observable, the values of municipal bonds and variable rate notes are categorized as Level 2. To the extent that these inputs are unobservable the values are categorized as Level 3.

Equity Securities (Common and Preferred Stock) – Equity securities traded in inactive markets and certain foreign equity securities are valued using inputs which include broker-dealer quotes, recently executed transactions adjusted for changes in the benchmark index, or evaluated price quotes received from independent pricing services that take into account the integrity of the market sector and issuer, the individual characteristics of the security, and information received from broker-dealers and other market sources pertaining to the issuer or security. To the extent that these inputs are observable, the values of equity securities are categorized as Level 2. To the extent that these inputs are unobservable the values are categorized as Level 3.

The Funds’ policy is to recognize transfers between levels at the end of the reporting period.

A summary of the inputs used at October 31, 2010 in valuing each Fund’s assets and liabilities is listed below:


Municipal:
			Level 2 –		Level 3 –
			Other Significant		Significant
	Level 1 –		Observable		Unobservable		Value at

There were no significant transfers between Levels 1 and 2 during the six months ended October 31, 2010.

A roll forward of fair value measurements using significant unobservable inputs (Level 3) for Municipal for the six months ended October 31, 2010, was as follows:


Municipal:
			Net

Total Investments	$	470,000	$	2,350		—		—	$	472,350

The net change in unrealized appreciation/depreciation of Level 3 investments which Municipal held at October 31, 2010 was $2,350. Net change in appreciation/depreciation is reflected on the Statements of Operations.

(c) Investment Transactions and Investment Income

Investment transactions are accounted for on the trade date. Securities purchased and sold on a when-issued 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 discount and amortization of premium 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.

PIMCO Municipal Income Funds Notes to Financial Statements

1. Organization and Significant Accounting Policies (continued)

(d) 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.

Accounting for uncertainty in income taxes 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 has resulted in no material impact to the Funds’ financial statements at October 31, 2010. The Funds’ federal tax returns for the prior three years remain subject to examination by the Internal Revenue Service.

(e) Dividends and Distributions – Common Shares

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 respective 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 GAAP. These “book-tax” differences are considered either temporary or permanent in nature. To the extent that 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 to shareholders from return of capital.

(f) 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 upon 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 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. To the extent a Fund does not cover its positions in reverse repurchase agreements (by segregating liquid assets at least equal in amount to the forward purchase commitment), the Fund’s uncovered obligations under the agreements will be subject to the Fund’s limitations on borrowings. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Funds 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 their trustee or receiver, whether to enforce the Funds’ obligation to repurchase the securities.

(g) Inverse Floating Rate Transactions – Residual Interest Municipal Bonds (”RIBs”) / Residual Interest Tax Exempt Bonds (”RITEs”)

The Funds 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. 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 issued” 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. The Funds may also invest in Inverse Floaters for the purpose of increasing leverage.

1. Organization and Significant Accounting Policies (continued)

The 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’ restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes. Inverse Floaters held by the Funds are exempt from registration under Rule 144A of the Securities Act of 1933.

In addition to general market risks, the Funds’ investments in Inverse Floaters may involve greater risk and volatility than an investment in a fixed rate bond, and the value of Inverse Floaters may decrease significantly when market interest rates increase. Inverse Floaters 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, Inverse Floaters 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 Inverse Floaters may be held could be terminated due to market, credit or other events beyond the Funds’ control, which could require the Funds to reduce leverage and dispose of portfolio investments at inopportune times and prices.

(h) When-Issued/Delayed-Delivery Transactions

When-issued or delayed-delivery 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 is sold on a delayed-delivery basis, the Funds do not participate in future gains and losses with respect to the security.

(i) 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. Cash overdraft charges, if any, are included in custodian and accounting agent fees.

(j) Interest Expense

Interest expense primarily relates to the Funds’ participation in floating rate notes held by third parties in conjunction with Inverse Floater transactions and reverse repurchase agreement transactions. Interest expense on reverse repurchase agreements is recorded as it is incurred.

2. Principal Risks

In the normal course of business, the Funds trade financial instruments and enter into financial transactions where risk of potential loss exists due to, among other things, changes in the market (market risk) or failure of the other party to a transaction to perform (counterparty risk). The Funds also are exposed to various risks such as, but not limited to, interest rate and credit risks.

Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates. As nominal interest rates rise, the value of certain fixed income securities held by the Funds are likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations. Duration is used primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e. yield) movements.

Variable and floating rate securities generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not

2. Principal Risks (continued)

generally increase in value if interest rates decline. Inverse floating rate securities may decrease in value if interest rates increase. Inverse floating rate securities may also exhibit greater price volatility than a fixed rate obligation with similar credit quality. When the Funds hold variable or floating rate securities, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the net asset value of the Funds’ shares.

The Funds are exposed to credit risk which is the risk of losing money if the issuer or guarantor of a fixed income security is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or to otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

The Funds are exposed to counterparty risk, or the risk that an institution or other entity with which the Funds have unsettled or open transactions will default. The potential loss to the Funds could exceed the value of the financial assets recorded in the Funds’ financial statements. Financial assets, which potentially expose the Funds to counterparty risk, consist principally of cash due from counterparties and investments. The Funds’ Sub-Adviser, Pacific Investment Management Company LLC (the “Sub-Adviser”), an affiliate of the Investment Manager, seeks to minimize the Funds’ counterparty risks by performing reviews of each counterparty and by minimizing concentration of counterparty risk by undertaking transactions with multiple customers and counterparties on recognized and reputable exchanges. Delivery of securities sold is only made once the Funds have received payment. Payment is made on a purchase once the securities have been delivered by the counterparty. The trade will fail if either party fails to meet its obligation.

3. Investment Manager/Sub-Adviser

Each Fund has an Investment Management Agreement (each an ”Agreement”) with the Investment Manager. Subject to the supervision of the Funds’ 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 each Agreement, the Investment Manager receives an annual fee, payable monthly, 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.

The Investment Manager has retained 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 of the Funds’ investment decisions. The Investment Manager, and not the Funds, pays a portion of the fee it receives as Investment Manager to the Sub-Adviser in return for its services.

New York Municipal		121,966,627		7,785,295		1,448,215		6,337,080

The difference between book and tax cost is attributable to Inverse Floater transactions.

6. Auction-Rate Preferred Shares

Municipal has 1,520 shares of Preferred Shares Series A, 1,520 shares of Preferred Shares Series B, 1,520 shares of Preferred Shares Series C, 1,520 shares of Preferred Shares Series D and 1,520 shares of Preferred Shares Series E outstanding, each with a liquidation preference of $25,000 per share plus any accumulated, unpaid dividends.

California Municipal has 2,000 shares of Preferred Shares Series A, 2,000 shares of Preferred Shares Series B and 2,000 shares of Preferred Shares Series C outstanding, each with a liquidation preference of $25,000 per share plus any accumulated, unpaid dividends.

New York Municipal has 1,880 shares of Preferred Shares Series A outstanding, with a liquidation preference of $25,000 per share plus any accumulated, unpaid dividends.

Dividends are accumulated daily at an annual rate (typically re-set every seven days) through auction procedures. Distributions of net realized capital gains, if any, are paid annually.

For the six months ended October 31, 2010, the annualized dividend rates for each Fund ranged from:


	High			Low			At October 31, 2010


Municipal:
Series A		0.472	%		0.350	%		0.442	%
Series B		0.472	%		0.381	%		0.427	%
Series C		0.472	%		0.350	%		0.427	%
Series D		0.472	%		0.350	%		0.427	%
Series E		0.487	%		0.350	%		0.442	%
California Municipal:
Series A		0.472	%		0.350	%		0.442	%
Series B		0.472	%		0.350	%		0.427	%
Series C		0.487	%		0.350	%		0.442	%
New York Municipal:
Series A		0.472	%		0.381	%		0.427	%

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 or paying any dividends or distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of Preferred Shares at their liquidation preference, plus any accumulated, unpaid dividends.

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

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,

October 31, 2010 (unaudited)

6. Auction-Rate Preferred Shares (continued)

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 holders have continued to receive dividends at the defined “maximum rate”, the higher of the 30-day “AA” Composite Commercial Paper Rate multiplied by a minimum of 110% (depending on the credit rating of the ARPS) 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 a minimum of 110% (depending on the credit rating of the ARPS) (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). 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.

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 Securities and Exchange Commission (“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 and certain of its 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 (the “MDL Court”). After a number of claims in the lawsuits were dismissed by the MDL Court, the parties entered into a stipulation of settlement, which was publicly filed with the MDL Court in April 2010, resolving all remaining claims, but the settlement remains subject to the approval of the MDL Court.

In addition, the Sub-Adviser is the subject of a lawsuit in the Northern District of Illinois Eastern Division in which the complaint alleges that plaintiffs each purchased and sold a 10-year Treasury note futures contract and suffered damages from an alleged shortage when the Sub-Adviser held both physical and futures positions in 10-year Treasury notes for its client accounts. In July 2007, the court granted class certification of a class consisting of those persons who purchased futures contracts to offset short positions between May 9, 2005 and June 30, 2005. The Sub-Adviser currently believes that the complaint is without merit and the Sub-Adviser intends to vigorously defend against this action.

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.

PIMCO Municipal Income Funds
Matters Relating to the Trustees’ Consideration of the Investment Management & Portfolio Management Agreements
(unaudited)

The Investment Company Act of 1940, as amended, requires that both the full Board of Trustees (the “Trustees”) and a majority of the non-interested Trustees (the “Independent Trustees”), voting separately, approve the Funds’ Management Agreements with the Investment Manager (the “Advisory Agreements”) and Portfolio Management Agreement (the “Sub-Advisory Agreements”, and together with the Advisory Agreements, the “Agreements”) between the Investment Manager and the Sub-Adviser. The Trustees met in person on June 22-23, 2010 (the “contract review meeting”) for the specific purpose of considering whether to approve the continuation of the Advisory Agreements and the Sub-Advisory Agreements. The Independent Trustees were assisted in their evaluation of the Agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from Fund management during the contract review meeting.

Based on their evaluation of factors that they deemed to be material, including those factors described below, the Board of Trustees, including a majority of the Independent Trustees, concluded that the continuation of the Funds’ Advisory Agreements and the Sub-Advisory Agreements, should be approved for a one-year period commencing July 1, 2010.

In connection with their deliberations regarding the continuation of the Agreements, the Trustees, including the Independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. As described below, the Trustees considered the nature, quality, and extent of the various investment management, administrative and other services performed by the Investment Manager or the Sub-Adviser under the applicable Agreement.

In connection with their contract review meeting, the Trustees received and relied upon materials provided by the Investment Manager which included, among other items: (i) information provided by Lipper Inc. (“Lipper”) on the total return investment performance (based on net assets) of the Funds for various time periods and the investment performance of a group of funds with substantially similar investment classifications/objectives as the Funds identified by Lipper and the performance of applicable benchmark indices, (ii) information provided by Lipper on the Funds’ management fees and other expenses and the management fees and other expenses of comparable funds identified by Lipper, (iii) information regarding the investment performance and management fees of comparable portfolios of other clients of the Sub-Advisers, (iv) the profitability to the Investment Manager and the Sub-Adviser from their relationship with the Funds for the one year period ended March 31, 2010, (v) descriptions of various functions performed by the Investment Manager and the Sub-Adviser for the Funds, such as portfolio management, compliance monitoring and portfolio trading practices, and (vi) information regarding the overall organization of the Investment Manager and the Sub-Adviser, including information regarding senior management, portfolio managers and other personnel providing investment management, administrative and other services to the Funds.

The Trustees’ conclusions as to the continuation of the Agreements were based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, attributing different weights to various factors.

As part of their review, the Trustees examined the Investment Manager’s and the Sub-Adviser’s abilities to provide high quality investment management and other services to the Funds. The Trustees considered the investment philosophy and research and decision-making processes of the Sub-Adviser; the experience of key advisory personnel of the Sub-Adviser responsible for portfolio management of the Funds; the ability of the Investment Manager and the Sub-Adviser to attract and retain capable personnel; the capability and integrity of the senior management and staff of the Investment Manager and the Sub-Adviser; and the level of skill required to manage the Funds. In addition, the Trustees reviewed the quality of the Investment Manager’s and the Sub-Adviser’s services with respect to regulatory compliance and compliance with the investment policies of the Funds; the nature and quality of certain administrative services the Investment Manager is responsible for providing to the Funds; and conditions that might affect the Investment Manager’s or the Sub-Adviser’s ability to provide high quality services to the Funds in the future under the Agreements, including each organization’s respective business reputation, financial condition and operational stability. Based on the foregoing, the Trustees concluded that the Sub-Adviser’s investment process, research capabilities and philosophy were well suited to each of the Funds given their respective investment objectives and policies, and that the Investment Manager and the Sub-Adviser would be able to continue to meet any reasonably foreseeable obligations under the Agreements.

Based on information provided by Lipper, the Trustees also reviewed each Fund’s total return investment performance as well as the performance of comparable funds identified by Lipper. In the course of their deliberations, the Trustees took into account information provided by the Investment Manager in connection with the contract review meeting, as well as

44 PIMCO Municipal Income Funds Semi-Annual Report ï 10.31.10

PIMCO Municipal Income Funds
Matters Relating to the Trustees’ Consideration of the Investment Management & Portfolio Management Agreements
(unaudited) (continued)

during investment review meetings conducted with portfolio management personnel during the course of the year regarding each Fund’s performance.

In assessing the reasonableness of each Fund’s fees under the Agreements, the Trustees considered, among other information, each Fund’s management fee and the total expense ratio as a percentage of average net assets attributable to common and preferred shares and the management fee and total expense ratios of comparable funds identified by Lipper.

For each of the Funds, the Trustees specifically took note of how each Fund compared to its Lipper peers as to performance, management fee expenses and total expenses. The Trustees noted that the Investment Manager had provided a memorandum containing comparative information on the performance and expenses information of the Funds compared to their Lipper peer categories. The Trustees noted that while the Funds are not charged a separate administration fee, it was not clear whether the peer funds in the Lipper categories were charged such a fee by their investment managers.

Municipal:

The Trustees noted that the expense group for the Fund provided by Lipper is small, consisting of a total of nine leveraged closed-end funds, not including the peer Funds in the AGI Fund Complex. The Trustees also noted that average net assets of the common shares of the funds in the peer group ranged from $262 million to $591 million, and that all of the funds are larger in asset size than the Fund. The Trustees also noted that the Fund was ranked seven out of nine funds in the expense peer group for actual management fees and eight out of nine for actual total expenses (with funds ranked first having the lowest fees/expenses and ranked ninth having the highest fees/expenses in the peer group).

With respect to performance, the Trustees also noted that the Fund outperformed its benchmark and had first quintile performance for the one-year period ended March 31, 2010 against a peer group of fifty nine funds. The Trustees also noted that the Fund had fifth quintile performance for the three-year period against a peer group of fifty nine funds and fifth quintile performance for the five-year period ended March 31, 2010 against a peer group of fifty eight funds.

California Municipal:

The Trustees noted that the expense group for the Fund provided by Lipper is small, consisting of a total of seven leveraged closed-end funds, not including the peer Funds in the AGI Fund Complex. The Trustees also noted that average net assets of the common shares of the funds in the peer group ranged from $107.7 million to $282.6 million, and that four of the funds are smaller in asset size than the Fund. The Trustees also noted that the Fund was ranked six out of seven funds in the expense peer group for actual management fees and actual total expenses (with funds ranked first having the lowest fees/expenses and ranked seventh having the highest fees/expenses in the peer group).

With respect to performance, the Trustees also noted that the Fund outperformed its benchmark and had first quintile performance for the one-year period ended March 31, 2010 against a peer group of twenty one funds. The Trustees also noted that the Fund had fourth quintile performance for the three-year period against a peer group of twenty one funds and second quintile performance for the five-year period ended March 31, 2010 against a peer group of twenty one funds.

New York Municipal:

The Trustees noted that the expense group for the Fund provided by Lipper is small, consisting of a total of seven leveraged closed-end funds, not including the peer Funds in the AGI Fund Complex. The Trustees also noted that average net assets of the common shares of the funds in the peer group ranged from $45.8 million to $190.5 million, and that two of the funds are larger in asset size than the Fund. The Trustees also noted that the Fund was ranked six out of seven funds in the expense peer group for actual management fees and for actual total expenses (with funds ranked first having the lowest fees/expenses and ranked seventh having the highest fees/expenses in the peer group).

With respect to performance, the Trustees also noted that the Fund outperformed its benchmark and had first quintile performance for the one-year period ended March 31, 2010 against a peer group of seventeen funds. The Trustees also noted that the Fund had fifth quintile performance for the three-year period and five-year period ended March 31, 2010 against a peer group of seventeen funds.

At the request of the Trustees, the Investment Manager and Sub-Adviser agreed to continue to provide performance information related to the Fund on a monthly basis.

PIMCO Municipal Income Funds
Matters Relating to the Trustees’ Consideration of the Investment Management & Portfolio Management Agreements
(unaudited) (continued)

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the Agreements, that they were satisfied with the Investment Manager’s and the Sub-Adviser’s responses and efforts to continue to improve the Funds’ investment performance. The Trustees agreed to reassess the services provided by the Investment Manager and Sub-Adviser under the Agreements in light of the Fund’s ongoing performance at each quarterly Board meeting.

The Trustees also considered the management fees charged by Sub-Adviser to other clients, including accounts with investment strategies similar to those of the Funds. The Trustees noted that the management fees paid by the Funds are generally higher than the fees paid by the open-end funds offered for comparison but were advised that there are additional portfolio management challenges in managing the Funds, such as the use of leverage and meeting a regular dividend.

The Trustees also took into account that the Funds have preferred shares outstanding, which increases the amount of fees received by the Investment Manager and the Sub-Adviser under the Agreements (because the fees are calculated based on either the Fund’s net assets or total managed assets, including assets attributable to preferred shares and other forms of leverage outstanding but not deducting any liabilities connected to the leverage). In this regard, the Trustees took into account that the Investment Manager and the Sub-Adviser have a financial incentive for the Funds to continue to have preferred shares outstanding, which may create a conflict of interest between the Investment Manager and the Sub-Adviser, on one hand, and the Funds’ common shareholders, on the other. In this regard, the Trustees considered information provided by the Investment Manager and the Sub-Adviser indicating that each Funds’ use of leverage through preferred shares continues to be appropriate and in the interests of the respective Fund’s common shareholders.

Based on a profitability analysis provided by the Investment Manager, the Trustees also considered the profitability of the Investment Manager and the Sub-Adviser from their relationship with each Fund and determined that such profitability was not excessive.

The Trustees also took into account that, as closed-end investment companies, the Funds do not currently intend to raise additional assets, so the assets of the Funds will grow (if at all) only through the investment performance of each Fund. Therefore, the Trustees did not consider potential economies of scale as a principal factor in assessing the fee rates payable under the Agreements.

Additionally, the Trustees considered so-called “fall-out benefits” to the Investment Manager and the Sub-Adviser, such as reputational value derived from serving as Investment Manager and Sub-Adviser to the Funds.

After reviewing these and other factors described herein, the Trustees concluded with respect to each Fund, within the context of their overall conclusions regarding the Agreements, that the fees payable under the Agreements represent reasonable compensation in light of the nature and quality of the services being provided by the Investment Manager and Sub-Adviser to the Funds.
