PIMCO Municipal Income Funds
Matters Relating to the Trustees Consideration of the Investment Management and Portfolio Management Agreements (unaudited)
The Investment Company Act of 1940 requires that both the full Board of Trustees (the ‘‘Trustees’’) and a majority of the non-interested (‘‘Independent’’) Trustees, voting separately, approve the Funds’ Management Agreements (the ‘‘Advisory Agreements’’) with the Investment Manager and Portfolio Management Agreements (the ‘‘Sub-Advisory Agreements’’, and together with the Advisory Agreements, the ‘‘Agreements’’) between the Investment Manager and the Sub-Adviser. The Trustees met on June 20 and 21, 2006 (the ‘‘contract review meeting’’) for the specific purpose of considering wheth er to approve 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 (the ‘‘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 Fund’s Advisory Agreements and the Sub-Advisory Agreements should be approved for a one-year period commencing July 1, 2006.
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 and the Sub-Adviser under the Agreements.
In connection with the Meeting, the Trustees received and relied upon materials provided by the Investment Manager which included, among other items: (i) information provided by Lipper Inc. 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, (ii) information provided by Lipper Inc. on the Funds’ management fees and other expenses and the management fees and other expenses of comparable funds identified by Lipper Inc., (iii) information regarding the investment performance and management fees of comparable portfolios of other clients of the Sub-Adviser, inclu ding institutional separate account and other clients, (iv) an estimate of the profitability to the Investment Manager from its relationship with the Funds for the twelve months ended March 31, 2006, (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, giving 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 In vestment 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 the Funds given their 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 Inc., the Trustees also reviewed each Fund’s total return investment performance as well as the performance of comparable funds identified by Lipper Inc. In the course of their deliberations, the Trustees took into account information provided by the Investment Manager in connection with the Meeting, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding each Fund’s performance.

PIMCO Municipal Income Funds
Matters Relating to the Trustees Consideration of the Investment Management and Portfolio Management Agreements (unaudited)
In assessing the reasonableness of each Fund’s fees under the Agreements, the Trustees considered, among other information, the Fund’s management fee and the total expense ratio as a percentage of average net assets attributable to common shares and the management fee and total expense ratios of comparable funds identified by Lipper Inc.
For each of the Funds, the Trustees specifically took note of how each Fund compared to its Lipper Inc. peers as to performance and management fee expenses. 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 Inc. categories were charged such a fee by their investment managers. Thus, the Trustees, at the recommendation of the Investment Manager, considered the total expenses of the Funds comparatively to the total expenses of the peer funds, recognizing that the fees for management and administrative services would be subsumed within the total expense ratio.
The Trustees noted that Municipal had outperformed its peer median and average group for the one-year and three-year periods ended April 30, 2006. The Trustees also noted that Municipal’s expense ratio (after taking into account waivers) was below the median and average for its peer group.
The Trustees noted that California Municipal outperformed its peer median and average group for the one-year and three-year periods ended April 30, 2006. The Trustees also noted that California Municipal’s expense ratio (after taking into account waivers) including the effect of preferred shares was significantly below the average and median for its peer group and excluding the effect of preferred shares was slightly below the median and average for its peer group.
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 relating to investment performance and the comparative positioning of each Fund with respect to the management fee paid to the Investment Manager.
The Trustees also considered the management fees charged by the Sub-Adviser to other clients, including institutional separate accounts with investment strategies similar to those of the Funds. Regarding the institutional separate accounts, they noted that the management fees paid by the Funds are generally higher than the fees paid by these clients of the Sub-Adviser, but were advised that the administrative burden for the Investment Manager and the Sub-Adviser with respect to the Funds are also relatively higher, due in part to the more extensive regulatory regime to which the Funds are subject in comparison to institutional separate accounts. The Trustees noted that the management fees paid by the Funds are generally higher t han the fees paid by the open-end funds but were advised that there are additional portfolio management challenge 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 the Fund’s total managed assets, including assets attributable to preferred shares and other forms of leverage outstanding). 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 Fund’s common shareholders, on the other. In this regard, the T rustees considered information provided by the Investment Manager and the Sub-Adviser indicating that each Fund’s use of leverage through preferred shares continues to be appropriate and in the interests of the Fund’s common shareholders.
Based on a profitability analysis provided by the Investment Manager, the Trustees also considered the estimated profitability of the Investment Manager from its 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, 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.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
There have been no material changes to the procedures by which shareholders may recommend nominees to the Fund’s Board of Trustees since the Fund last provided disclosure in response to this item.
ITEM 11. CONTROLS AND PROCEDURES
 |  |  |
| (a) | The Registrant’s principal executive and principal financial officers have evaluated the Registrant’s disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940) and have concluded that the Registrant’s disclosure controls and procedures were effective as of a date within 90 days of the filing. However subsequent to the Fund’s fiscal period ended October 31, 2006 as discussed below, the Registrant has enhanced controls related to the identification of relevant contractual terms and conditions of transfers of securities in connection with the purchase by the Registrant of certain inverse floating rate obligations that require accounting treatment under Statement of Financial Accounting Standards No. 140 (‘‘Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities’’) (‘‘SFAS 140’’). |
 |  |  |
| (b) | There were no changes in the Registrant’s internal controls over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940, as amended) that occurred during the second fiscal quarter of the period covered by this report that materially affected, or is reasonable likely to affect, the Registrant’s internal control over financial reporting. In December 2006, the principal executive and financial officers became aware of matters relating to the Registrant’s purchase of certain inverse floating rate obligations that required enhancements to certain controls. The Registrant’s management determined that controls relating to the review and analysis of the relevant contractual terms and conditions of transf ers of securities in connection with the purchase of certain inverse floating rate obligations were not effective in identifying whether these transfers qualified for sale accounting under the provisions of SFAS 140. The Registrant’s management is taking such further actions as are necessary to revise its controls and procedures in order to increase the effectiveness of these controls and procedures in identifying such transactions that require accounting treatment under SFAS 140. |
ITEM 12. EXHIBITS

| (a) | Exhibit 99.302 Cert. – Certification pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 |
