After its latest cut in the federal funds rate target on June 25, the Federal Reserve Open Market Committee (the "Fed") indicated that it intended to remain in an accommodative stance for a considerable period in an attempt to get the economy back onto a solid footing. The short end of the tax-free money market yield curve was largely flat through much of the year, though it inverted in the last quarter as seasonal redemptions pushed yields for the shortest maturities higher. Yields on municipal money market paper were highly attractive relative to taxable instruments. Among one-year maturities the ratio of municipals to taxable yields exceeded 90 percent for much of the year and for overnight paper the ratio at times rose above 100 percent. The accommodative monetary policy appeared to be having a positive effect as corporate profits and overall GDP growth began to show signs of life. As the year drew to a close, these improvements were reflected in better prospects for most municipalities, with tax receipts on the rise and the general trend toward widespread credit downgrades slowing. Many states worked to close budget gaps through a combination of increased fees and service cuts as well as one-time measures such as tobacco bond receipts and long-term refinancing. New York and California continued to lead the country in both issuance and deficits, with California experiencing downgrades in its general obligation bond ratings from both Standard & Poor's and Moody's. Against this backdrop, the issuance of traditional notes rose considerably in 2003. Rising deficits led many issuers to turn to the capital markets for temporary borrowing to meet shortfalls in cash flow. Long-term bond issuance also rose as many states and local issuers moved to lock in low financing rates for capital expenditures and to refinance higher-cost debt. Overall municipal issuance for calendar year 2003 exceeded the record levels of 2002, setting a new all-time high. PERFORMANCE ANALYSIS As of December 31, 2003, Morgan Stanley California Tax-Free Daily Income Trust had net assets of more than $249 million. For the twelve-month period ended December 31, 2003, the Fund provided a total return of 0.33 percent. For the seven-day period ended December 31, 2003, the Fund provided an effective annualized yield of 0.45 percent and a current yield of 0.45 percent, while its 30-day moving average yield for December was 0.35 percent. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. The general shape of the yield curve and the very low level of interest rates reduced incentives for extending the portfolio's maturity structure. As a result, Morgan Stanley California Tax-Free Daily Income Trust spent the period with an emphasis on the short-to-intermediate maturity range within the municipal money market. This approach had the added benefit of positioning the Fund defensively against any potential increases in interest rates at the short end of the curve. The uncertain state of the economy also made us largely unwilling to introduce added interest-rate risk into the Fund's portfolio. 2 <Page> Our general caution was reflected in the Fund's composition. By the end of the period, the portfolio was comprised of 75 percent short-term variable rate paper, with the remainder in short-term tax-exempt commercial paper and fixed-rate notes. As always, we remained highly selective in our security selection and thoroughly screened potential purchases to ensure that they met the Fund's credit criteria. We were especially cautious in our purchases of longer fixed-rate paper, given California's ongoing budgetary difficulties. <Table> PORTFOLIO COMPOSITION Variable Rate Municipal Obligations 75.3% Commercial Paper 15.4 Municipal Notes 9.3 MATURITY SCHEDULE 1 - 30 Days 82.8% 31 - 60 Days 2.4 61 - 90 Days -- 91 - 120 Days -- 121 + Days 14.8 </Table> SUBJECT TO CHANGE DAILY.

ORGANIZATION AND ACCOUNTING POLICIES Morgan Stanley California Tax-Free Daily Income Trust (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a diversified, open-end management investment company. The Fund's investment objective is to provide a high level of daily income which is exempt from federal and California income tax, consistent with stability of principal and liquidity. The Fund was organized as a Massachusetts business trust on April 25, 1988, and commenced operations on July 22, 1988. The following is a summary of significant accounting policies: A. VALUATION OF INVESTMENTS -- Portfolio securities are valued at amortized cost, which approximates market value. B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. C. FEDERAL INCOME TAX POLICY -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and nontaxable income to its shareholders. Accordingly, no federal income tax provision is required. D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and distributions to shareholders as of the close of each business day. E. USE OF ESTIMATES -- The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates. 2. INVESTMENT MANAGEMENT AGREEMENT Pursuant to an Investment Management Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Manager"), the Fund pays the Investment Manager a management fee, accrued daily and payable monthly, by applying the following annual rates to the net assets of the Fund determined as of the close of each business day: 0.50% to the portion of the daily net assets not exceeding $500 million; 0.425% to the portion of the daily net assets exceeding $500 million but not exceeding $750 million; 0.375% to the portion of the daily net assets exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of the daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.325% to the portion of the daily net assets exceeding $1.5 billion but not exceeding $2 billion; 0.30% to the portion 10 <Page> of the daily net assets exceeding $2 billion but not exceeding $2.5 billion; 0.275% to the portion of the daily net assets exceeding $2.5 billion but not exceeding $3 billion; and 0.25% to the portion of the daily net assets exceeding $3 billion. For the year ended December 31, 2003, the Investment Manager voluntarily waived $5,087 of its fee. 3. PLAN OF DISTRIBUTION Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager, is the distributor of the Fund's shares and in accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act, finances certain expenses in connection with the promotion of sales of Fund shares. Reimbursements for these expenses are made in monthly payments by the Fund to the Distributor, which will in no event exceed an amount equal to a payment at the annual rate of 0.15% of the Fund's average daily net assets during the month. Expenses incurred by the Distributor pursuant to the Plan in any fiscal year will not be reimbursed by the Fund through payments accrued in any subsequent fiscal year. For the year ended December 31, 2003, the distribution fee was accrued at the annual rate of 0.10%. 4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES The cost of purchases and proceeds from sales/maturities of portfolio securities for the year ended December 31, 2003, aggregated $575,750,850 and $601,322,000, respectively. Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is the Fund's transfer agent. At December 31, 2003, the Fund had transfer agent fees and expenses payable of approximately $900. The Fund has an unfunded noncontributory defined benefit pension plan covering certain independent Trustees of the Fund who will have served as independent Trustees for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. Aggregate pension costs for the year ended December 31, 2003, included in Trustees' fees and expenses in the Statement of Operations amounted to $7,264. At December 31, 2003, the Fund had an accrued pension liability of $60,294 which is included in accrued expenses in the Statement of Assets and Liabilities. On December 2, 2003, the Trustees voted to close the plan to new participants, eliminate the future benefits growth due to increases to compensation after July 31, 2003, and effective April 1, 2004, establish an unfunded deferred compensation plan which allows each independent Trustee to defer payment of all or a portion of the fees he receives for serving on the Board of Trustees throughout the year. 11 <Page> 5. SHARES OF BENEFICIAL INTEREST Transactions in shares of beneficial interest, at $1.00 per share, were as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED DECEMBER 31, 2003 DECEMBER 31, 2002 ----------------- ----------------- Shares sold 387,832,372 477,774,441 Shares issued in reinvestment of dividends 820,367 1,897,542 ------------- ------------- 388,652,739 479,671,983 Shares redeemed (414,427,878) (480,386,236) ------------- ------------- Net decrease in shares outstanding (25,775,139) (714,253) ============= ============= </Table> 6. EXPENSE OFFSET The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 7. LEGAL MATTERS The Investment Manager, certain affiliates of the Investment Manager and certain investment companies advised by the Investment Manager or its affiliates, including the Fund, are named as defendants in a number of recently filed, similar class action complaints. These complaints generally allege that defendants, including the Fund, violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Investment Manager and certain affiliates of the Investment Manager allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Investment Manager or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Investment Manager or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaints seek, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The defendants intend to move to dismiss these actions and otherwise vigorously to defend them. While the Fund believes that it has meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of the litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 12 <Page> MORGAN STANLEY CALIFORNIA TAX-FREE DAILY INCOME TRUST FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, -------------------------------------------------------------------- 2003 2002 2001 2000 1999 ---------- ---------- ----------- ---------- ---------- SELECTED PER SHARE DATA: Net asset value, beginning of period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 ---------- ---------- --------- --------- --------- Net income from investment operations 0.003 0.007 0.017 0.028 0.023 Less dividends from net investment income (0.003) (0.007) (0.017) (0.028) (0.023) ---------- ---------- --------- --------- --------- Net asset value, end of period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 ========== ========== ========= ========= ========= TOTAL RETURN 0.33% 0.71% 1.76% 2.86% 2.28% RATIOS TO AVERAGE NET ASSETS: Expenses (before expense offset) 0.70%(1)(2) 0.69% 0.69% 0.69% 0.72%(1) Net investment income 0.33%(2) 0.70% 1.72% 2.81% 2.25% SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 249,496 $ 275,271 $ 275,985 $ 272,990 $ 281,541 </Table> - ---------- (1) DOES NOT REFLECT THE EFFECT OF EXPENSE OFFSET OF 0.01%.

Our procedures included confirmation of securities owned as of December 31, 2003, by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

STATEMENT OF PRINCIPLES The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor's independence from the Fund. The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee's administration of the engagement of the independent auditor. The SEC's rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee ("GENERAL PRE-APPROVAL"); or require the specific pre-approval of the Audit Committee or its delegate ("SPECIFIC PRE-APPROVAL"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. - ---------- (1) This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the "POLICY"), adopted as of the date above, supercedes and replaces all prior versions that may have been adopted from time to time. 3 <Page> The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee's responsibilities to pre-approve services performed by the Independent Auditors to management. The Fund's Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors' independence. 2. DELEGATION As provided in the Act and the SEC's rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 3. AUDIT SERVICES The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund's financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items. In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 4. AUDIT-RELATED SERVICES 4 <Page> Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC's rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR. The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 5. TAX SERVICES The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor's independence, and the SEC has stated that the Independent Auditors may provide such services. Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 6. ALL OTHER SERVICES The Audit Committee believes, based on the SEC's rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC's rules on auditor independence. 5 <Page> The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. 8. PROCEDURES All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund's Chief Financial Officer and must include a detailed description of the services to be rendered. The Fund's Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund's Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence. The Audit Committee has designated the Fund's Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund's Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund's Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund's Chief Financial Officer or any member of management. 9. ADDITIONAL REQUIREMENTS The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor's independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 6 <Page> 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence. 10. COVERED ENTITIES Covered Entities include the Fund's investment adviser(s) and any entity controlling, controlled by or under common control with the Fund's investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund's audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include: MORGAN STANLEY RETAIL FUNDS Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc. Morgan Stanley Investment Management Morgan Stanley Investments LP Van Kampen Asset Management Inc. Morgan Stanley Services Company, Inc. Morgan Stanley Distributors Inc. Morgan Stanley Trust FSB MORGAN STANLEY INSTITUTIONAL FUNDS Morgan Stanley Investment Management Inc. Morgan Stanley Investments LP Morgan Stanley & Co. Incorporated Morgan Stanley Distribution, Inc. Morgan Stanley AIP GP LP Morgan Stanley Alternative Investment Partners LP (e)(2) Beginning with non-audit service contracts entered into on or after May 6, 2003, the audit committee also is required to pre-approve services to Covered Entities to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Registrant. 100% of such services were pre-approved by the audit committee pursuant to the Audit Committee's pre-approval policies and procedures (attached hereto). (f) Not applicable. (g) See table above. (h) The audit committee of the Board of Trustees has considered whether the provision of services other than audit services performed by the auditors to the Registrant and Covered Entities is compatible with maintaining the auditors' independence in performing audit services. 7 <Page> Item 5.
