The performance of the Fund's four share classes varies because each has
different expenses. The Fund's total returns assume the reinvestment of all
distributions but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. See Performance Summary for standardized
performance and benchmark information.

Because Class B shares incurred lower expenses under the 12b-1 Plan than did
Class A shares for the six months ended June 30, 2007, the total operating
expense ratio for Class B shares was lower and, as a result, the performance of
Class B shares was higher than that of the Class A shares. There can be no
assurance that this will continue to occur in the future as the maximum fees
payable by Class B shares under the 12b-1 Plan are higher than those payable by
Class A shares. Currently, the Distributor has agreed to waive the 12b-1 fee on
Class B shares to the extent it exceeds 0.24% of the average daily net assets of
such shares on an annualized basis. The Distributor may discontinue this waiver
in the future.

MARKET CONDITIONS

Economic growth was initially sluggish but became decidedly more positive as the
period progressed. Weaker consumer spending and rising energy prices weighed on
the economy in the first quarter of 2007. At the same time, troubles in the
sub-prime mortgage market surfaced, intensifying concerns about the already weak
residential housing sector. Against this backdrop, speculation began to emerge
that the Federal Open Market Committee (the "Fed") might reduce its target
federal funds rate. As the months progressed, energy prices continued to rise
and productivity gains slowed, but employment growth remained strong and various
economic indicators began to improve. This led to anticipation of a rebound in
economic growth and renewed concerns about inflation, which effectively
dispelled expectations of a near-term ease in Fed monetary policy and yields
moved higher across the Treasury curve. In the last weeks of June, however,
yields declined when news of the failure of two of Bear Stearns'
mortgage-related hedge funds fueled a flight-to-quality Treasury market rally.
Despite the market's volatility and the changing outlook for the economy and
monetary policy during the period, the target federal funds rate has remained
unchanged at 5.25 percent for the past year.

Municipal bond yields generally followed the same path as Treasury yields,
declining in January and February then rising for most of the remainder of the
period. Yields on long-term issues (as represented by the 30-year AAA rated
municipal bond) moved from 4.10 percent at the beginning of the period to 4.55
percent in mid-June, then declined to 4.45 percent by the end of the period.
Yields on 10-year bonds moved in a similar pattern while yields on short-term
municipals remained relatively stable. As such, the slope of the curve steepened
for the overall period, with a 75 basis point yield advantage, or "pick-up", for
30-year maturities relative to one-year maturities at the end of June. Despite
the steepening, however, the curve still ended the period relatively flat

 2


in historic terms as the yield pick-up from one to 30 years has averaged 150
basis points over the past three years.

Long-term municipal bonds performed relatively in line with Treasuries until
late June when the flight to quality helped Treasuries outperform. The 30-year
municipal-to-Treasury yield ratio, which measures the relative attractiveness of
these two sectors, held steady at 85 percent through March, then rose slightly
to end the period at 87 percent. A rising ratio indicates that municipals
underperformed Treasuries but became more attractive on a relative price basis.

Issuance of municipal bonds jumped nearly 50 percent in the first calendar
quarter, due primarily to a surge in refundings, but fell off in the second
quarter as rising interest rates discouraged borrowers from issuing new debt at
higher rates. Nonetheless, new issue volume for the first half of 2007 totaled
$226 billion, a 27 percent increase versus the same six-month period in 2006.
The top five issuing states during the reporting period were California, Texas,
Florida, New York, and Pennsylvania. Together, these states accounted for 47
percent of total market volume.

New issue volume in California totaled more than $41 billion during the period,
a 75 percent increase versus the same period last year. The state continued to
enjoy a generally good economic footing, with a large and diverse economic base,
a small positive general fund balance, an improved financial outlook, and a
relatively well-funded pension system. Additionally, California's debt levels
remain moderate despite accelerating debt issuance. Per capita and median
household incomes were above national averages but the state's unemployment rate
was slightly higher than the nation's average.

As a final note, the U.S. Supreme Court agreed in May to review Davis v. The
State of Kentucky Department of Revenue, a case that questions whether
differential tax treatment of in-state and out-of-state municipal bond interest
is constitutional. The executive branch of the Commonwealth of Kentucky is
seeking to overturn a state court ruling that it is unconstitutional to treat
interest on bonds issued by government entities in their state more favorably
for tax purposes than interest on bonds issued in other states. Given that the
majority of states currently exempt only interest on their municipal bonds from
state income taxes, the market will be closely watching this case.

PERFORMANCE ANALYSIS

All share classes of Morgan Stanley California Tax-Free Income Fund
underperformed the Lehman Brothers California Exempt Index and the Lipper
California Municipal Debt Funds Index for the six months ended June 30, 2007,
assuming no deduction of applicable sales charges.

During the reporting period, the Fund's interest-rate positioning continued to
reflect our anticipation of higher rates. As a result, at the end of June, the
Fund's option-adjusted duration* stood at 7.4 years. This defensive posture
proved additive to performance as interest rates rose for the overall period.
The Fund's performance was also enhanced by several holdings that appreciated
when they were pre-refunded.**

                                                                               3


The Fund maintained its high quality bias with approximately 86 percent of the
portfolio rated A or better as of end of period. In particular, the Fund was
overweighted in higher-rated bonds in sectors such as public power, higher
education, water and sewer, and transportation. This high credit-quality profile
impeded performance since lower-rated bonds outperformed during the period. That
said, we have been adding to positions in BBB rated securities, which helped
boost returns. It should also be noted that the Fund contained no bonds subject
to the Alternative Minimum Tax (AMT) during the period. These positions were
eliminated from the portfolio prior to the start of the year and we intend to
continue to run the Fund as AMT free at least through the end of 2007.

Reflecting a commitment to diversification, the Fund's net assets of
approximately $469 million were invested among 12 long-term sectors and 57
credits. As of the close of the period, the Fund's largest allocations were to
the water and sewer, hospital and transportation sectors.

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

* A measure of the sensitivity of a bond's price to changes in interest rates,
expressed in years. Each year of duration represents an expected 1 percent
change in the price of a bond for every 1 percent change in interest rates. The
longer a bond's duration, the greater the effect of interest-rate movements on
its price. Typically funds with shorter durations perform better in rising
interest-rate environments, while funds with longer durations perform better
when rates decline.

** Pre-refunding, or advance refunding, is a financing structure under which new
bonds are issued to repay an outstanding bond issue on its first call date.

Performance data quoted represents past performance, which is no guarantee of
future results and current performance may be lower or higher than the figures
shown. For most recent month-end performance figures, please visit
www.morganstanley.com or speak with your Financial Advisor. Investment returns
and principal value will fluctuate and fund shares, when redeemed, may be worth
more or less than their original cost. The table does not reflect the deduction
of taxes that a shareholder would pay on fund distributions or the redemption of
fund shares. Performance for Class A, Class B, Class C, and Class D shares will
vary due to differences in sales charges and expenses.

*   The maximum front-end sales charge for Class A is 4.25%.

**  The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%. The
    CDSC declines to 0% after six years.

+   The maximum contingent deferred sales charge for Class C is 1.0% for shares
    redeemed within one year of purchase.

++  Class D has no sales charge.

     California issued municipal bonds rated at least Baa or BBB by Moody's
     Investors Service, Inc. or Standard & Poor's Corporation, respectively and
     with maturities of 2 years or greater. The Index is unmanaged and its
     returns do not include any sales charges or fees. Such costs would lower
     performance. It is not possible to invest directly in an index.

(2)  The Lipper California Municipal Debt Funds Index is an equally weighted
     performance index of the largest qualifying funds (based on net assets) in
     the Lipper California Municipal Debt Funds classification. The Index, which
     is adjusted for capital gains distributions and income dividends, is
     unmanaged and should not be considered an investment. There are currently
     30 funds represented in this Index. The Fund is in the Lipper California
     Municipal Debt Funds classification as of the date of this report.

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments and redemption fees;
and (2) ongoing costs, including advisory fees; distribution and service (12b-1)
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 01/01/07 - 06/30/07.

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 and do not reflect any transactional costs, such as sales
charges (loads) and redemption fees. 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. In addition, if these transactional costs
were included, your costs would have been higher.

</Table>

- ------------------
* Expenses are equal to the Fund's annualized expense ratios of 1.02,% 0.95%,
  1.51% and 0.78% for Class A, Class B, Class C and Class D shares,
  respectively, 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 ratios would have been
  1.06%, 0.99%, 1.55% and 0.82% for Class A, Class B, Class C and Class D
  shares, respectively.

  Because Class B shares incurred lower expenses under the 12b-1 Plan than did
  Class A shares for the six months ended June 30, 2007, the total operating
  expense ratio for Class B shares was lower and, as a result the performance of
  Class B shares was higher than that of the Class A shares. There can be no
  assurance that this will continue to occur in the future as the maximum fees
  payable by Class B shares under the 12b-1 Plan are higher than those payable
  by Class A shares. Currently, the Distributor has agreed to waive the 12b-1
  fee on Class B shares to the extent it exceeds 0.24% of the average daily net
  assets of such shares on an annualized basis. The Distributor may discontinue
  this waiver in the future.

                                                                               9


INVESTMENT ADVISORY AGREEMENT APPROVAL

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 under the Advisory
Agreement, including portfolio management, investment research 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 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 advisory and administrative 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. The Board also concluded that the overall quality of the advisory and
administrative services was satisfactory.

PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


On a regular basis, the Board reviews the performance of all funds in the Morgan
Stanley Fund Complex, including the Fund, compared to their peers, paying
specific attention to the underperforming funds. In addition, the Board
specifically reviewed the Fund's performance for the one-, three- and five-year
periods ended November 30, 2006, as shown in a report provided by Lipper (the
"Lipper Report"), compared to the performance of comparable funds selected by
Lipper (the "performance peer group"). The Board discussed with the Adviser the
performance goals and the actual results achieved in managing the Fund. The
Board concluded that the Fund's performance was competitive with that of its
performance peer group.

FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE
INVESTMENT STRATEGIES


The Board noted that the Adviser did not manage any other proprietary funds with
investment strategies comparable to those of the Fund.

 10


FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


The Board reviewed the advisory and administrative fee (together, the
"management fee") rate and total expense ratio of the Fund as compared to the
average management fee rate and average total expense ratio for funds, selected
by Lipper (the "expense peer group"), managed by other advisers with investment
strategies comparable to those of the Fund, as shown in the Lipper Report. The
Board concluded that the Fund's management fee rate and total expense ratio were
competitive with those of its expense peer group.

BREAKPOINTS AND ECONOMIES OF SCALE


The Board reviewed the structure of the Fund's management fee schedule under the
Management Agreement and noted that it includes breakpoints. The Board also
reviewed the level of the Fund's management fee and noted that the fee, as a
percentage of the Fund's net assets, would decrease as net assets increase
because the management fee includes breakpoints. The Board concluded that the
Fund's management fee would reflect economies of scale as assets increase.

PROFITABILITY OF THE ADVISER AND AFFILIATES


The Board considered information concerning the costs incurred and profits
realized by the Adviser and 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. Based on its review of the information it received, the Board
concluded that the profits earned by the Adviser and affiliates were not
excessive in light of the advisory, administrative and other services provided
to the Fund.

FALL-OUT BENEFITS


The Board considered so-called "fall-out benefits" derived by the Adviser and
affiliates from their relationship with the Fund and the Morgan Stanley Fund
Complex, such as sales charges on sales of Class A shares and "float" benefits
derived from handling of checks for purchases and sales of Fund shares, through
a broker-dealer affiliate of the Adviser. The Board also considered that a
broker-dealer affiliate of the Adviser receives from the Fund 12b-1 fees for
distribution and shareholder services. The Board concluded that the float
benefits were relatively small and the sales charges and 12b-1 fees were
competitive with those of other broker-dealers.

                                                                              11


SOFT DOLLAR BENEFITS


The Board considered whether the Adviser realizes any benefits from commissions
paid to brokers who execute securities transactions for the Fund ("soft
dollars"). The Board noted that the Fund invests only in fixed income
securities, which do not generate soft dollars.

ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS


The Board considered whether the Adviser is financially sound and has the
resources necessary to perform its obligations under the Management Agreement.
The Board concluded that the Adviser has the financial resources necessary to
fulfill its obligations under the Management Agreement.

HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER


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 Board's confidence in the competence and integrity of
the senior managers and key personnel of the Adviser. The Board concluded 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


On April 25, 2007, 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
until April 30, 2008. On June 20, 2007, the Board again considered and weighed
all of the above factors and concluded that it would be in the best interest of
the Fund and its shareholders to approve renewal of the Management Agreement to
continue until June 30, 2008.

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley California Tax-Free Income Fund (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 current income which is exempt from federal and
California income tax, consistent with the preservation of capital. The Fund was
organized as a Massachusetts business trust on April 9, 1984 and commenced
operations on July 11, 1984. On July 28, 1997, the Fund converted to a multiple
class share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within eighteen
months, six years and one year, respectively. Class D shares are not subject to
a sales charge. Additionally, Class A shares, Class B shares and Class C shares
incur distribution expenses.

The Fund will assess a 2% redemption fee on Class A shares, Class B shares,
Class C shares, and Class D shares, which is paid directly to the Fund, for
shares redeemed within seven days of purchase, subject to certain exceptions.
The redemption fee is designed to protect the Fund and its remaining
shareholders from the effects of short-term trading.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; and (3) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized

 20

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED) continued

cost based on their value on the 61st day. Short-term debt securities having a
maturity date of sixty days or less at the time of purchase are valued at
amortized cost.

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 and are included in interest income. Interest income is
accrued daily.

C. Multiple Class Allocations -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

D. Floating Rate Note Obligations Related to Securities Held -- The Trust enters
into transactions in which it transfers to Dealer Trusts ("Dealer Trusts"),
fixed rate bonds in exchange for cash and residual interests in the Dealer
Trusts' assets and cash flows, which are in the form of inverse floating rate
investments. The Dealer Trusts fund the purchases of the fixed rate bonds by
issuing floating rate notes to third parties and allowing the Fund to retain
residual interest in the bonds. The Fund enters into shortfall agreements with
the Dealer Trusts which commit the Fund to pay the Dealer Trusts, in certain
circumstances, the difference between the liquidation value of the fixed rate
bonds held by the Dealer Trusts and the liquidation value of the floating rate
notes held by third parties, as well as any shortfalls in interest cash flows.
The residual interests held by the Fund (inverse floating rate investments)
include the right of the Fund (1) to cause the holders of the floating rate
notes to tender their notes at par at the next interest rate reset date, and (2)
to transfer the municipal bond from the Dealer Trusts to the Fund, thereby
collapsing the Dealer Trusts. The Fund accounts for the transfer of bonds to the
Dealer Trusts as secured borrowings, with the securities transferred remaining
in the Fund's investment assets, and the related floating rate notes reflected
as trust liabilities under the caption "floating rate note obligations" on the
Statement of Assets and Liabilities. The Fund records the interest income from
the fixed rate bonds under the caption "Interest Income" and records the
expenses related to floating rate note obligations and any administrative
expenses of the dealer trusts under the caption "Interest and residual trust
expenses" in the Fund's Statement of Operations. The notes issued by the Dealer
Trusts have interest rates that reset weekly and the floating rate note holders
have the option to tender their notes to the Dealer Trusts for redemption at par
at each reset date. At June 30, 2007, Fund investments with a value of
$38,832,970 are held by the Dealer Trusts and serve as collateral for the
$28,500,000 in floating rate note obligations outstanding at that date.

NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED) continued

obligations and interest rates in effect at June 30, 2007 are presented in the
Portfolio of Investments.

E. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Fund is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract. Such receipts or payments known as
variation margin are recorded by the Fund as unrealized gains and losses. Upon
closing of the contract, the Fund realizes a gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.

F. 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 nontaxable income to its shareholders. Therefore, no provision for
federal income taxes is required. The Fund files tax returns with the U.S.
Internal Revenue Service and various states. Generally, the tax authorities can
examine all tax returns filed for the last three years. 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. The Fund
adopted the provisions of the Financial Accounting Standards Board's (FASB)
Interpretation number 48 Accounting for Uncertainty in Income Taxes, on June 30,
2007. As of June 30, 2007, this did not result in an impact to the Fund's
financial statements.

G. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

H. 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 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 Fund's net assets determined as of the close of each
business day: 0.47% to the portion of the daily net assets not exceeding $500
million; 0.445% to the portion of the daily net assets exceeding $500 million
but not exceeding $750 million; 0.42% to the portion of the daily net assets
exceeding $750 million but not

 22

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED) continued

exceeding $1 billion; 0.395% to the portion of the daily net assets exceeding $1
billion but not exceeding $1.25 billion; and 0.37% to the portion of the daily
net assets in excess of $1.25 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 0.08% to the Fund's daily net assets.

The Investment Adviser has agreed to cap the Fund's operating expenses (except
for brokerage and 12b-1 fees) 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 such operating expenses exceed 0.60%
of the average daily net assets of the Fund on an annualized basis. Such
voluntary waivers may be terminated at any time without notice.

3. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Adviser and Administrator. The
Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act. The Plan provides that the Fund will pay the Distributor a fee
which is accrued daily and paid monthly at the following annual rates: (i) Class
A -- up to 0.25% of the average daily net assets of Class A shares; (ii) Class
B -- up to 0.75% of the lesser of: (a) the average daily aggregate gross sales
of the Class B shares since the inception of the Fund (not including
reinvestment of dividend or capital gain distributions) less the average daily
aggregate net asset value of the Class B shares redeemed since the Fund's
inception upon which a contingent deferred sales charge has been imposed or
waived; or (b) the average daily net assets of Class B shares; and (iii) Class
C -- up to 0.75% of the average daily net assets of Class C shares.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that there were no excess expenses as of
June 30, 2007.

At June 30, 2007, included in the Statement of Assets and Liabilities, is a
receivable from the Fund's Distributor which represents payments due to be
reimbursed to the Fund under the Plan. Because the Plan is what is referred to
as a "reimbursement plan", the Distributor reimburses to the Fund any

                                                                              23

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED) continued

12b-1 fees collected in excess of the actual distribution expenses incurred.
This receivable represents this excess amount as of June 30, 2007.

The Distributor has agreed to waive the 12b-1 fee on Class B shares to the
extent it exceeds 0.24% of the average daily net assets of such shares on an
annualized basis. The Distributor may discontinue this waiver in the future. For
the six months ended June 30, 2007, the distribution fee was accrued for Class B
shares at the annual rate of 0.17%.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.75% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors and other authorized
financial representatives at the time of sale may be reimbursed in the
subsequent calendar year. For the six months ended June 30, 2007, the
distribution fee was accrued for Class A shares and Class C shares at the annual
rate of 0.24% and 0.73%, respectively.

The Distributor has informed the Fund that for the six months ended June 30,
2007, it received contingent deferred sales charges from certain redemptions of
the Fund's Class A shares, Class B shares and Class C shares of $1,426 , $64,196
and $3,332, respectively and received $39,115 in front-end sales charges from
sales of the Fund's Class A shares. The respective shareholders pay such charges
which are not an expense of the Fund.

4. Security Transactions and Transactions with Affiliates

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended June 30, 2007 aggregated
$23,925,494 and $36,174,181, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator 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, 2007 included in Trustees' fees
and expenses in the Statement of Operations amounted to $2,945. At June 30,
2007, the Fund had an accrued pension liability of $60,316 which is included in
accrued expenses in the Statement of Assets and Liabilities.

 24

Morgan Stanley California Tax-Free Income Fund
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2007 (UNAUDITED) continued

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.

5. Purposes of and Risks Relating to Certain Financial Instruments

The Fund may invest a portion of its assets in inverse floating rate
instruments, either through outright purchases of inverse floating rate
securities or through the transfer of bonds to a Dealer Trust in exchange for
cash and residual interests in the Dealer Trust. These investments are typically
used by the Fund in seeking to enhance the yield of the portfolio. These
instruments typically involve greater risks than a fixed rate municipal bond. In
particular, these instruments are acquired through leverage or may have leverage
embedded in them and therefore involve many of the risks associated with
leverage. Leverage is a speculative technique that may expose the Fund to
greater risk and increased costs. Leverage may cause the Fund's net asset value
to be more volatile than if it had not been leveraged because leverage tends to
magnify the effect of any increases or decreases in the value of the Fund's
portfolio securities. The use of leverage may also cause the Fund to liquidate
portfolio positions when it may not be advantageous to do so in order to satisfy
its obligations with respect to inverse floating rate instruments.

To hedge against adverse interest rate changes, the Fund may invest in financial
futures contracts or municipal bond index futures contracts ("futures
contracts").

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the value of the underlying securities. Risks may also
arise upon entering into these contracts from the potential inability of the
counterparties to meet the terms of their contracts.

                                                                              25

8. 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 generally accepted accounting principles.
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, 2006, the Fund had temporary book/tax differences primarily
attributable to book amortization of discounts on debt securities.

9. Accounting Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Fund's financial statement disclosures.

                                                                              27
