Notes to Schedule 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. The Fund’s 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 or delayed-delivery basis are marked to market daily until settlement at the forward settlement date.

The Board of Trustees (the “Board”) has adopted procedures for valuing portfolio securities and other financial derivative instruments in circumstances where market quotes are not readily available, and has delegated the responsibility for applying the valuation methods to Allianz Global Investors Fund Management LLC (“the Investment Manager”) and Pacific Investment Management Company LLC (the “Sub-Adviser”). The Fund’s Valuation Committee was established by the Board to oversee the implementation of the Fund’s valuation methods and to make fair value determinations on behalf of the Board, as instructed. The Sub-Adviser monitors the continued appropriateness of methods applied and determines if adjustments should be made in light of market changes, events affecting the issuer, or other factors. If the Sub-Adviser determines that a valuation method may no longer be appropriate, another valuation method may be selected, or the Valuation Committee will be convened to consider the matter and take any appropriate action in accordance with procedures set forth by the Board. The Board shall review the appropriateness of the valuation methods and these methods may be amended or supplemented from time to time by the Valuation Committee.

Benchmark pricing procedures are used as the basis for setting the base price of a fixed income security and for subsequently adjusting the price proportionally to market value changes of a pre-determined security deemed to be comparable in duration, generally a U.S. Treasury or sovereign note based on country of issuance. The base price may be a broker-dealer quote, transaction price, or an internal value as derived by analysis of market data. The base price of the security may be reset on a periodic basis based on the availability of market data and procedures approved by the Valuation Committee. The validity of the fair value is reviewed by the Sub-Adviser on a periodic basis and may be amended as the availability of market data indicates a material change.

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 Fund to value investments may differ from the value that would be realized if the investments were sold, and these differences could be material. The Fund’s net asset value (“NAV”) 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.

(a) Private Placement—Restricted as to resale and may not have a readily available market. Securities with an aggregate value of $10,441,071, representing 2.0% of total investments.

(b) Illiquid.

(c) Pre-refunded bonds are collateralized by U.S. Government or other eligible securities which are held in escrow and used to pay principal and interest and retire the bonds at the earliest refunding date (payment date).

(d) 144A—Exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions exempt from registration, typically only to qualified institutional buyers. Unless otherwise indicated, these securities are not considered to be illiquid.

(e) When-issued or delayed-delivery. To be settled/delivered after July 31, 2013.

(f) In default.

(g) Fair—Valued—Security with a value of $468,468, representing 0.1% of total investments.

(h) Inverse Floater—The interest rate shown bears an inverse relationship to the interest rate on another security or the value of an index. The interest rate disclosed reflects the rate in effect on July 31, 2013.

(i) Variable Rate Notes—Instruments whose interest rates change on specified date (such as a coupon date or interest payment date) and/or whose interest rates vary with changes in a designated base rate (such as the prime interest rate). The interest rate disclosed reflects the rate in effect on July 31, 2013.

(j) Residual Interest Bonds held in Trust—Securities represent underlying bonds transferred to a separate securitization trust established in a tender option bond transaction in which the Fund acquired the residual interest certificates. These securities serve as collateral in a financing transaction.

(k) Restricted. The aggregate acquisition cost of such security is $932,489. The aggregate value is $468,468, representing 0.1% of total investments.

(l) Rates reflect the effective yields at purchase date.

(m) At July 31, 2013, the cost basis of portfolio securities for federal income tax purposes was $482,811,720. Gross unrealized appreciation was $31,903,399; gross unrealized depreciation was $10,977,993; and net unrealized appreciation was $20,925,406. The difference between book and tax cost was attributable to the differing treatment of Inverse Floater transactions.

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 Fund has the ability to access

• Level 2 – valuations based on other significant observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates or other market corroborated inputs

• Level 3 – valuations based on significant unobservable inputs (including the Sub-Adviser’s or Valuation Committee’s own assumptions and securities whose price was determined by using a single broker’s quote)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following are certain inputs and techniques that the Fund generally uses to evaluate how to classify each major category of assets and liabilities for Level 2 and Level 3, in accordance with Generally Accepted Accounting Principles.

U.S. Treasury Obligations — U.S. Treasury obligations are valued by independent pricing services based on pricing models that evaluate the mean between the most recently quoted bid and ask price. The models also take into consideration data received from active market makers and broker-dealers, yield curves, and the spread over comparable U.S. Treasury issues. The spreads change daily in response to market conditions and are generally obtained from the new issue market and broker-dealer sources. To the extent that these inputs are observable, the values of U.S. Treasury obligations are categorized as Level 2. To the extent that these inputs are unobservable, the values are categorized as Level 3.

Government Sponsored Enterprise and Mortgage-Backed Securities — Government sponsored enterprise and mortgage-backed securities are valued by independent pricing services using pricing models based on inputs that include issuer type, coupon, cash flows, mortgage prepayment projection tables and Adjustable Rate Mortgage evaluations that incorporate index data, periodic and life caps, the next coupon reset date, and the convertibility of the bond. To the extent that these inputs are observable, the values of government sponsored enterprise and mortgage-backed securities are categorized as Level 2. To the extent that these inputs are unobservable, the values are categorized as Level

Municipal Bonds & Notes and Variable Rate Notes — Municipal bonds & notes 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 or note insurance. To the extent that these inputs are observable, the values of municipal bonds & notes and variable rate notes are categorized as Level 2. To the extent that these inputs are unobservable, the values are categorized as Level 3.

The valuation techniques used by the Fund to measure fair value during the three months ended July 31, 2013 were intended to maximize the use of observable inputs and to minimize the use of unobservable inputs.

The Fund’s policy is to recognize transfers between levels at the end of the reporting period. 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 the 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 techniques used. Investments categorized as Level 1 or 2 as of period end may have been transferred between Levels 1 and 2 since the prior period due to changes in the valuation method utilized in valuing the investments.

A summary of the inputs used at July 31, 2013 in valuing the Fund’s assets and liabilities is listed below (refer to the Schedule of Investments for more detailed information on Investments in Securities):

	Level 1 - Quoted Prices		Level 2 - Other Significant Observable Inputs		Level 3 - Significant Unobservable Inputs		Value at 7/31/13

At July 31, 2013, there were no transfers between Levels 1 and 2.

A roll forward of fair value measurements using significant unobservable inputs (Level 3) for the three months ended July 31, 2013, was as follows:

	Beginning Balance 4/30/13		Purchases		Sales		Accrued Discount (Premiums)		Net Realized Gain (Loss)		Net Change in Unrealized Appreciation/ Depreciation			Transfers into Level 3*		Transfers out of Level 3		Ending Balance 7/31/13

The following table presents additional information about valuation techniques and inputs used for investments that are measured at fair value and categorized within Level 3 at July 31, 2013:

Investments in Securities - Assets	Ending Balance at 7/31/13		Valuation Technique Used	Unobservable Inputs	Input Values
Municipal Bonds & Notes
Alaska	$	451,800	Third-Party Pricing Vendor	Projected Revenue Stream	$	50.20
Kansas		550,000	Third-Party Pricing Vendor	Projected Revenue Stream	$	55.00
Tennessee		468,468	Benchmark Pricing	Security Price Reset	$	49.87

* Transferred out of Level 2 into Level 3 because updated information on evaluated prices by third-party pricing vendors were not available.

The net change in unrealized appreciation/depreciation of Level 3 investments held at July 31, 2013 was $(3,882).
