Fund Report

(unaudited)

For the six months ended June 30, 2011

Market Conditions

State and local tax collections rose in the first half of 2011 as an expanding economy and tax increases passed during the recession eased city and state budget woes. State governments collect most of their revenue from sales and income taxes, which can fall fast in response to recessions but also snap back quickly. By contrast, local governments continue to struggle in large part because falling property values have depressed property taxes, their primary source of tax revenue.

June 30 marked the end of most state and local governments’ fiscal years. Almost all state and local governments are required by their constitutions or charters to pass balanced budgets. All but one state (Minnesota) passed their budgets before the start of fiscal year 2012. Furthermore, state tax revenues have grown in each of the past five quarters, and some states have made progress on the pension reform front. Given the improving credit picture for states and the lack of a significant default in the first half of 2011, the number of headlines about municipal credit risk has declined.

In response to budget pressures, most states have shown both an ability and willingness to raise taxes and cut expenditures. There have been various solutions so far including $23.9 billion of tax increases for fiscal year 2010. Spending cuts, as measured by the Rockefeller Institute, can be hard to quantify but have shown to be both widespread and deep. The Center on Budget Practice and Policies counted cuts in health care across 31 states, services to elderly and disabled across 29 states, K-12 education cuts in 33 states and cuts to higher education in 33 states. In addition, employee furloughs have been widespread and municipalities have employed temporary solutions to bridge gaps.

In keeping with the political shift toward fiscal tightening, municipal bond issuance remains about half of what it was last year, with volume for the first six months of 2011 down almost 44% relative to the same period in 2010. Variable rate demand note (VRDN) issuance so far in 2011 has totaled $4.6 billion through June, more than 45 percent below the total sales for the same period last year.

The California legislature passed an on-time fiscal 2012 budget that relies on one-time measures and includes up to $2.5 billion of “trigger cuts” if actual revenues fall short of estimates. Having an enacted budget and better-than-expected revenues in recent months should allow the state to avoid near-term shortfalls. Ratings agency Standard & Poor’s recently revised its outlook on California’s rating (A-) from Negative to Stable. California’s ratings (A1/A-/A-) now have Stable outlooks from each of the major rating agencies (Moody’s, Standard & Poor’s, and Fitch).

Performance Analysis

As of June 30, 2011, Morgan Stanley California Tax-Free Daily Income Trust had net assets of approximately $597 million and an average portfolio maturity of 34 days. For the six-month period ended June 30, 2011, the Fund provided a total return of 0.00 percent. For the seven-day period ended June 30, 2011, the Fund provided an effective annualized yield of 0.01 percent (subsidized) and –0.54 percent (non-subsidized) and a current yield of 0.01 percent (subsidized) and –0.54 percent (non-

2

subsidized), while its 30-day moving average yield for June was 0.01 percent (subsidized) and –0.50 percent (non-subsidized). Yield quotations more closely reflect the current earnings of the Fund. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Despite much improved market liquidity and strong demand for bonds, it is clearly a time for careful diligence and diversification of investment portfolios. Protecting the safety and liquidity of the Portfolio’s assets remained our first priority. In the recent uncertain markets, our emphasis has been on managing exposure to institutions under stress.

Recent economic data has been sending mixed signals and many investors are likely to continue to tread cautiously. Barring any unexpected shocks to the market, we believe that rates are likely to remain low through 2011. Moreover, while it may be difficult politically, simply practicing fiscal austerity should be enough for states to overcome near-term fiscal challenges. Raising taxes and cutting services should prove to be enough, budgets will likely be passed and state finances will likely improve as the economy continues to recover. During this period of ongoing uncertainty, we continue to maintain a watchful eye on state and local economies.

There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Fund in the future.

Investment Strategy

The Fund will normally invest at least 80 percent of its net assets in high quality, short-term securities that are municipal obligations that pay interest exempt from federal and California income taxes. The Investment Adviser seeks to maintain the Fund’s share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment.

An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Morgan Stanley also delivers the semiannual and annual reports to fund shareholders and makes these reports available on its public web site, www.morganstanley.com. Each Morgan Stanley fund also files a complete schedule of portfolio holdings with the SEC for the fund’s first and third fiscal quarters on Form N-Q and monthly holdings for each money market fund on form N-MFP. Morgan Stanley does not deliver these reports to shareholders, nor are the first and third fiscal quarter reports posted to the Morgan Stanley public web site. However, the holdings for each money market fund are posted to the Morgan Stanley public web site. You may obtain the Form N-Q filings (as well as the Form N-CSR, N-CSRS and N-MFP filings) by accessing the SEC’s web site, http://www.sec.gov.

Expense Example

(unaudited)

As a shareholder of the Fund, you incur ongoing costs, including advisory fees; shareholder servicing fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 01/01/11 – 06/30/11.

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the second line of the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds that have transactional costs, such as sales charges (loads) or exchange fees.

	Beginning		Ending		Expenses Paid
	Account Value		Account Value		During Period@
					01/01/11–
	01/01/11		06/30/11		06/30/11
Actual (0.00% return)	$	1,000.00	$	1,000.00	$	0.84
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,023.95	$	0.85

@ Expenses are equal to the Fund’s annualized expense ratio of 0.17% multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). If the fund had borne all of its expenses, the annualized expense ratio would have been 0.67%.

Investment Advisory Agreement Approval

(unaudited)

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and equity and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Fund’s Administrator (as defined herein) under the administration agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser’s expense. (The Investment Adviser and the Administrator together are referred to as the “Adviser” and the advisory and administration agreements together are referred to as the “Management Agreement.”) The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper, Inc. (“Lipper”).

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and advisory services to the Fund. The Board determined that the Adviser’s portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Fund and supported its decision to approve the Management Agreement.

Performance, Fees and Expenses of the Fund

The Board reviewed the performance, fees and expenses of the Fund compared to its peers, as determined by Lipper, and to appropriate benchmarks where applicable. The Board discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. When considering a fund’s performance, the Board and the Adviser place emphasis on trends and longer-term returns (focusing on one-year, three-year and five-year performance, as of December 31, 2010, or since inception, as applicable). When a fund underperforms its benchmark and/or its peer group average, the Board and the Adviser discuss the causes of such underperformance and, where necessary, they discuss specific changes to investment strategy or investment personnel. The Board noted that the Fund’s performance was below its peer group average for the one-, three- and five-year periods. The Board discussed with the Adviser the level of the advisory and administration fees (together, the “management fee”) for this Fund relative to comparable funds and/or other accounts advised by the Adviser and/or compared to its peers as determined by Lipper. In addition to the management fee, the Board also reviewed the Fund’s total expense ratio. The Board noted that the Fund’s management fee and total expense ratio were lower than its peer group average. After

6

discussion, the Board concluded that (i) the Fund’s performance was acceptable, and (ii) the management fee and total expense ratio were competitive with its peer group average.

Economies of Scale

The Board considered the size and growth prospects of the Fund and how that relates to the Fund’s total expense ratio and particularly the Fund’s management fee rate, which includes breakpoints. In conjunction with its review of the Adviser’s profitability, the Board discussed with the Adviser how a change in assets can affect the efficiency or effectiveness of managing the Fund and whether the management fee level is appropriate relative to current and projected asset levels and/or whether the management fee structure reflects economies of scale as asset levels change. The Board has determined that its review of the actual and potential economies of scale of the Fund supports its decision to approve the Management Agreement.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last year from their relationship with the Fund and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. The Board has determined that its review of the analysis of the Adviser’s expenses and profitability supports its decision to approve the Management Agreement.

Other Benefits of the Relationship

The Board considered other benefits to the Adviser and its affiliates derived from their relationship with the Fund and other funds advised by the Adviser. These benefits may include, among other things, “float” benefits derived from handling of checks for purchases and sales, research received by the Adviser generated from commission dollars spent on funds’ portfolio trading and fees for distribution and/or shareholder servicing. The Board reviewed with the Adviser each of these arrangements and the reasonableness of the Adviser’s costs relative to the services performed. The Board has determined that its review of the other benefits received by the Adviser or its affiliates supports its decision to approve the Management Agreement.

Resources of the Adviser and Historical Relationship Between the Fund and the Adviser

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board also reviewed and considered the historical relationship between the Fund and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Fund’s operations and the

7

Board’s confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement and that it is beneficial for the Fund to continue its relationship with the Adviser.

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund’s Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund’s business.

General Conclusion

After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of the Fund and its shareholders to approve renewal of the Management Agreement for another year. In reaching this conclusion the Board did not give particular weight to any single factor referenced above. The Board considered these factors over the course of numerous meetings, some of which were in executive session with only the independent Board members and their counsel present. It is possible that individual Board members may have weighed these factors differently in reaching their individual decisions to approve the Management Agreement.

1. 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 seek to provide as high a level of daily income exempt from federal and California income tax as is 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 fair value, in accordance with Rule 2a-7 under the Act. Investments in mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day.

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. Dividend income and other distributions are recorded on the ex-dividend date. Discounts are accreted and premiums are amortized over the life of the respective securities and are included in interest income. Interest income is accrued daily as earned.

C. Federal Income Tax Policy — It is the Fund’s policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and non-taxable income to its shareholders. Therefore, no federal income tax provision is required. The Fund files tax returns with the U.S. Internal Revenue Service, New York State and New York City. The Fund recognizes the tax effects of a tax position taken or expected to be taken in a tax return only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date. The more-likely-than-not threshold must continue to be met in each reporting period to support continued recognition of the benefit. The difference between the tax benefit recognized in the financial statements for a tax position taken and the tax benefit claimed in the income tax return is referred to as an unrecognized tax benefit. There are no unrecognized tax benefits in the accompanying financial statements. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in “other expenses” in the Statement of Operations. Each of the tax years in the four-year period ended December 31, 2010 remains subject to examination by taxing authorities.

D. Dividends and Distributions to Shareholders — The Fund records dividends and distributions to shareholders as of the close of each business day.

E. When-Issued/Delayed Delivery Securities — The Fund may purchase or sell when-issued and delayed delivery securities. Securities purchased on a when-issued or delayed delivery basis are purchased for

Morgan Stanley California Tax-Free Daily Income Trust

Notes to Financial Statements - June 30, 2011 (unaudited) continued

delivery beyond the normal settlement date at a stated price and yield, and no income accrues to the Fund on such securities prior to delivery. Payment and delivery for when-issued and delayed delivery securities can take place up to 120 days after the date of the transaction. When a Fund enters into a purchase transaction on a when-issued or delayed delivery basis, it establishes either a segregated account in which it maintains liquid assets in an amount at least equal in value to the Fund’s commitments to purchase such securities or designates such assets as segregated on a Fund’s records. Purchasing securities on a when-issued or delayed delivery basis may involve a risk that the market price at the time of delivery may be lower than the agreed upon purchase price, in which case there could be an unrealized loss at the time of delivery. Purchasing investments on a when-issued or delayed delivery basis may be considered a form of leverage which may increase the impact that gains (losses) may have on the Fund.

F. Use of Estimates — The preparation of financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates.

G. Indemnifications — The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

2. Fair Valuation Measurements

Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value as the value that the Fund would receive to sell an investment or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. ASC 820 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in valuing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs); and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in valuing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund’s investments. The inputs are summarized in the three broad levels listed below.

•  Level 1 — unadjusted quoted prices in active markets for identical investments

•  Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

19

Morgan Stanley California Tax-Free Daily Income Trust

Notes to Financial Statements - June 30, 2011 (unaudited) continued

•  Level 3 — significant unobservable inputs including the Fund’s own assumptions in determining the fair value of investments. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, or the appropriate stock exchange (for exchange-traded securities), analysis of the issuer’s financial statements or other available documents and, if necessary, available information concerning other securities in similar circumstances

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

The following is a summary of the inputs used as of June 30, 2011 in valuing the Fund’s investments carried at fair value:

			FAIR VALUE MEASUREMENTS AT JUNE 30, 2011 USING
			UNADJUSTED		OTHER
			QUOTED PRICES IN		SIGNIFICANT		SIGNIFICANT
			ACTIVE MARKETS FOR		OBSERVABLE		UNOBSERVABLE
			IDENTICAL INVESTMENTS		INPUTS		INPUTS

Total	$	629,811,033		—	$	629,811,033		—

Transfers between investment levels may occur as the markets fluctuate and/or the availability of data used in an investment’s valuation changes. The Fund recognizes transfers between the Levels as of the end of the period. As of June 30, 2011, the Fund did not have any investments transfer between investment levels.

3. Investment Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment Advisors Inc. (the “Investment Adviser”), the Fund pays the Investment Adviser an advisory 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: 0.45% to the portion of the daily net assets not exceeding $500 million; 0.375% to the portion of the daily net assets exceeding $500 million but not exceeding $750 million; 0.325% to the portion of the daily net assets exceeding $750 million but not exceeding $1 billion; 0.30% to the portion of the daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.275% to the portion of the daily net assets exceeding

Morgan Stanley California Tax-Free Daily Income Trust

Notes to Financial Statements - June 30, 2011 (unaudited) continued

$1.5 billion but not exceeding $2 billion; 0.25% to the portion of the daily net assets exceeding $2 billion but not exceeding $2.5 billion; 0.225% to the portion of the daily net assets exceeding $2.5 billion but not exceeding $3 billion; and 0.20% to the portion of the daily net assets exceeding $3 billion.

Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the “Administrator”), an affiliate of the Investment Adviser, the Fund pays an administration fee, accrued daily and payable monthly, by applying the annual rate of 0.05% to the Fund’s daily net assets.

Under a Sub-Administration Agreement between the Administrator and State Street Bank and Trust Company (“State Street”), State Street provides certain administrative services to the Fund. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Fund.

The Investment Adviser has agreed to cap the Fund’s operating expenses by assuming the Fund’s “other expenses” and/or waiving the Fund’s advisory fees, and the Administrator has agreed to waive the Fund’s administrative fees, to the extent that such operating expenses exceed 0.60% of the average daily net assets of the Fund on an annualized basis. These fee waivers and/or expense reimbursements are expected to continue for at least one year or until such time that the Board of Trustees acts to discontinue all or a portion of such waivers and/or expense reimbursements when it deems such action is appropriate.

4. Shareholder Services Plan

Pursuant to a Shareholder Services Plan (the “Plan”), the Fund may pay Morgan Stanley Distributors Inc. (the “Distributor”) as compensation for the provision of services to shareholders a service fee up to the rate of 0.15% on an annualized basis of the average daily net assets of the Fund.

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 six months ended June 30, 2011, the distribution fee was accrued at the annual rate of 0.10%.

The Distributor, Investment Adviser and Administrator have agreed to waive/reimburse all or a portion of the Fund’s shareholder servicing fee, investment advisory fee and administration fee, respectively, to the extent that total expenses exceed total income of the Fund on a daily basis. For the six months ended June 30, 2011, the Distributor waived $75,047, the Investment Adviser waived $612,050 and the Administrator waived $15,770. These fee waivers and/or expense reimbursements are expected to continue for one year or until such time that the Board of Trustees acts to discontinue all or a portion of such waivers and/or expense reimbursements when it deems such action is appropriate.

5. Security Transactions and Transactions with Affiliates

The Fund invests in the Institutional Class of the Morgan Stanley Institutional Liquidity Funds Government Portfolio (the “Liquidity Funds”), an open-end management investment company managed by the Adviser. Investment advisory fees paid by the Fund are reduced by an amount equal to its pro-rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Funds.

A summary of the Fund’s transactions in shares of the Liquidity Funds during the six months ended June 30, 2011 is as follows:

Value		Purchases		Sales		Dividend		Value
December 31, 2010		at cost		Proceeds		Income		June 30, 2011
$	0	$	57,800,000	$	57,800,000	$	40	$	0

Morgan Stanley Services Company Inc., an affiliate of the Investment Adviser and Distributor, is the Fund’s transfer agent.

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. The Trustees voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the six months ended June 30, 2011, included in “trustees’ fees and expenses” in the Statement of Operations amounted to $2,114. At June 30, 2011, the Fund had an accrued pension liability of $60,282, which is included in “accrued expenses and other payables” in the Statement of Assets and Liabilities.

The Fund has an unfunded Deferred Compensation Plan (the “Compensation Plan”), which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund.

6. Shares of Beneficial Interest

Transactions in shares of beneficial interest, at $1.00 per share, were as follows:

	FOR THE SIX			FOR THE YEAR
	MONTHS ENDED			ENDED
	JUNE 30, 2011			DECEMBER 31, 2010

Net increase (decrease) in shares outstanding		512,822,562			(21,784,196	)

7. Federal Income Tax Status

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 either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital.

As of December 31, 2010, the Fund had temporary book/tax differences primarily attributable to nondeductible expenses.

8. Expense Offset

The Fund has entered into an arrangement with State Street (“Custodian”), whereby credits realized on uninvested cash balances were used to offset a portion of the Fund’s expenses. If applicable, these custodian credits are shown as “expense offset” in the Statement of Operations.

9. Accounting Pronouncement

In May 2011, FASB issued Accounting Standards Update (“ASU”) 2011-04. The amendments in this update are the results of the work of FASB and the International Accounting Standards Board to develop common requirements for measuring fair value and for disclosing information about fair value measurements, which are effective during interim and annual periods beginning after December 15, 2011. Consequently, these amendments improve the comparability of fair value measurements presented and disclosed in the financial statements prepared in accordance with U.S. GAAP and International Financial Reporting Standards.

In connection with this approval, there will be no change in the nature of the services currently provided to the Fund through their existing advisory and distribution relationships.

Change in Independent Registered Public Accounting Firm (unaudited)

On June 7, 2011, Deloitte & Touche LLP were dismissed as Independent Registered Public Accounting Firm of the Fund.

The reports of Deloitte & Touche LLP on the financial statements of the Fund for the past two fiscal years contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

In connection with its audits for the two most recent fiscal years, there have been no disagreements with Deloitte & Touche LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte & Touche LLP, would have caused them to make reference thereto in their reports on the financial statements for such years.

On June 7, 2011, the Fund, with the approval of its Board of Trustees and its Audit Committee, engaged Ernst & Young LLP as its new Independent Registered Public Accounting Firm.
