                                       OF
                               CASH ASSETS TRUST

                                                                  November, 2005

Dear Investor:

      We are pleased to provide you with the Semi-Annual  Report for The Pacific
Capital Funds of Cash Assets Trust for the six-month  period ended September 30,
2005.

      The enclosed  Semi-Annual  Report includes the three series of Cash Assets
Trust (the "Trust"): Pacific Capital Cash Assets Trust, Pacific Capital Tax-Free
Cash Assets Trust and Pacific  Capital U.S.  Government  Securities  Cash Assets
Trust and its two classes of shares: Original Shares and Service Shares.

      As always,  the Federal Reserve (the "Fed") kept an  ever-watchful  eye on
the  economy  and as a result,  the Fed's  monetary  policy had an impact on the
short-term debt markets.

      Despite the  devastation  caused by hurricanes  Katrina and Rita, the U.S.
economy registered better than expected growth during the current report period.
Both  consumer  and business  spending  remained  relatively  strong in light of
rising interest rates and energy prices.  The  manufacturing  sector was upbeat,
indicating strength in both orders and production that suggests capital spending
by businesses will continue to expand at a reasonable pace. Real estate remained
a particular  area of strength as housing  starts kept rising and mortgage rates
stayed relatively low.  Additionally,  the labor market was quite resilient with
payrolls declining less than expected given the effects of the two hurricanes.

      While acknowledging the extraordinary  damage from this year's hurricanes,
the Fed's policy makers raised the target for its benchmark  short-term interest
rates to  3.75%,  the  11th  such  increase  in the  past  two  years.  (The Fed
subsequently  raised the Federal Funds rate yet again on November 2nd to a level
of 4.00%.) The Federal  Funds rate is the interest rate banks charge one another
on overnight loans and the Fed's primary tool for influencing economic activity.
As you are aware, rises in interest rates usually mean higher borrowing cost for
consumers and businesses and a slowdown in economic activity.

      In  raising  short-term  interest  rates on the  heels of the  devastation
caused  by the  hurricanes,  the Fed  concluded  that the  prospects  of  higher
inflation,  due in large part to rising energy  prices,  remained more worrisome
than the possibility of slower economic growth.

      As mentioned in previous report letters, yields on money market funds like
the Trust,  move in concert  with rate  policies  pursued by the Fed. By keeping
each of the funds' average weighted  portfolio  maturity  relatively  short, the
Trust's Investment Adviser, the Asset Management Group of



Bank of Hawaii,  has taken  advantage of the rise in short-term  interest rates.
Each of the  Trust's  portfolios  continues  to provide  competitive  returns to
alternative  short-term  investment  opportunities  without  wavering from their
conservative investment guidelines.

      Looking forward,  we are optimistic that each of the Pacific Capital Funds
of Cash Assets Trust will continue to provide investors with competitive returns
without compromising safety of principal.

      All those  associated  with the  management  of your cash reserves wish to
thank  you for the  continued  support  and  confidence  you have  placed in the
Pacific Capital Funds of Cash Assets Trust.

                                             Sincerely,


/s/ Diana P. Herrmann                                /s/ Lacy B. Herrmann

                            THE PACIFIC CAPITAL FUNDS
                              OF CASH ASSETS TRUST
                          NOTES TO FINANCIAL STATEMENTS
                         SEPTEMBER 30, 2005 (UNAUDITED)

1. ORGANIZATION

      Cash  Assets  Trust  (the  "Trust")  was  organized  on May 7,  1984  as a
Massachusetts  business trust and is registered under the Investment Company Act
of 1940 (the "1940 Act") as an open-end investment company.

      The Trust consists of the following three investment  portfolios (referred
to  individually as a "Fund" and  collectively as the "Funds"):  Pacific Capital
Cash  Assets  Trust  ("Cash  Fund") (a  diversified  portfolio  which  commenced
operations  on December 5, 1984),  Pacific  Capital  Tax-Free  Cash Assets Trust
("Tax-Free  Fund") (a  non-diversified  portfolio which commenced  operations on
April 4, 1989), and Pacific Capital U.S. Government Securities Cash Assets Trust
("Goverment Fund") (a diversified  portfolio which commenced operations on April
4, 1989).  The Trust is authorized to issue for each Fund an unlimited number of
shares of $0.01 par value in two classes of shares;  the  Original  Shares Class
and the Service Shares Class.  The Original  Shares Class includes all currently
outstanding  shares of each Fund that were issued prior to January 20, 1995, the
date on which the Capital  structure  was changed to include two classes  rather
than one.  The two classes of shares are  substantially  identical,  except that
Service  Shares  bear the fees that are payable  under the Trust's  Distribution
Plan.

2. SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant  accounting policies followed by
the Funds in the preparation of their financial statements.  The policies are in
conformity with U.S. generally accepted accounting principles.

a)    PORTFOLIO  VALUATION:  Each Fund's portfolio  securities are valued by the
      amortized  cost method  permitted in  accordance  with Rule 2a-7 under the
      1940 Act, which, after considering accrued interest thereon,  approximates
      market. Under this method, a portfolio security is valued at cost adjusted
      for  amortization of premiums and accretion of discounts.  Amortization of
      premiums and accretion of discounts are included in interest income.

b)    SECURITIES   TRANSACTIONS  AND  RELATED  INVESTMENT   INCOME:   Securities
      transactions  are  recorded on the trade date.  Realized  gains and losses
      from  securities  transactions  are reported on the identified cost basis.
      Interest income is recorded daily on the accrual basis and is adjusted for
      amortization  of premiums  and  accretion of discounts as discussed in the
      preceding paragraph.

c)    Determination  of net asset value and  calculation  of  expenses:  The net
      asset value per share for each class of the Funds' shares is determined as
      of 4:00 p.m.  New York time on each day that the New York  Stock  Exchange
      and the custodian are open by dividing the value of the assets of the Fund
      allocable to that class less Fund  liabilities  allocable to the class and
      any liabilities  charged directly to the class,  exclusive of surplus,  by
      the total number of shares of the class outstanding.

d)    MULTIPLE CLASS  ALLOCATIONS:  Investment  income,  realized and unrealized
      gains and losses, if any, and expenses other than class specific expenses,
      are allocated  daily to each class of shares based upon the  proportion of
      net  assets  of each  class.  Class  specific  expenses  are  borne by the
      affected



      class.  Service  fee  payments  under Rule  12b-1 are borne  solely by and
      charged to the Service Shares based on net assets of that class.

e)    FEDERAL INCOME TAXES: It is the policy of each Fund to continue to qualify
      as a regulated  investment company by complying with the provisions of the
      Internal  Revenue Code applicable to certain  investment  companies.  Each
      Fund  intends  to make  distributions  of income  and  securities  profits
      sufficient to relieve it from all, or  substantially  all,  Federal income
      and excise taxes.

f)    REPURCHASE  AGREEMENTS:  It is each Fund's  policy to monitor  closely the
      creditworthiness  of all  firms  with  which  it  enters  into  repurchase
      agreements,  and to take possession of, or otherwise  perfect its security
      interest  in,  securities   purchased  under  agreements  to  resell.  The
      securities purchased under agreements to resell are marked to market every
      business day in order to compare the value of the collateral to the amount
      of the "loan" (repurchase  agreements being defined as "loans" in the 1940
      Act),  including the accrued interest earned thereon.  If the value of the
      collateral  is less  than  102% of the  loan  plus  the  accrued  interest
      thereon, additional collateral is required from the borrower.

g)    USE OF ESTIMATES:  The  preparation of financial  statements in conformity
      with U.S. generally accepted accounting  principles requires management to
      make estimates and assumptions  that affect the reported amounts of assets
      and liabilities and disclosure of contingent assets and liabilities at the
      date of the financial statements and the reported amounts of increases and
      decreases  in net assets  from  operations  during the  reporting  period.
      Actual results could differ from those estimates.

3. FEES AND RELATED PARTY TRANSACTIONS

a)    MANAGEMENT ARRANGEMENTS:

      The Asset Management  Group of Bank of Hawaii (the  "Adviser"),  serves as
Investment  Adviser  to the  Funds.  In this  role,  under  Investment  Advisory
Agreements,  the Adviser  supervises the Funds' investments and provides various
services. Aquila Investment Management LLC the ("Administrator"), a wholly-owned
subsidiary of Aquila  Management  Corporation,  the Trust's founder and sponsor,
serves as the Administrator for the Trust under an Administration Agreement with
the Funds. The Administrator  provides all administrative  services to the Funds
other than those relating to the investment  portfolios.  Specific details as to
the  nature  and  extent  of the  services  provided  by  the  Adviser  and  the
Administrator  are  more  fully  defined  in the  Prospectus  and  Statement  of
Additional  Information of the Trust.  For their  services,  the Adviser and the
Administrator each receive a fee which is payable monthly and computed as of the
close of  business  each day on the net  assets  of each  Fund at the  following
annual rates:

            Cash Fund - On net assets up to $325 million, the fee is paid to the
            Adviser and the Administrator at the annual rate of 0.33% and 0.17%,
            respectively, and on net assets above that amount at the annual rate
            of 0.43% and 0.07%, respectively.



            Tax-Free Fund - On net assets up to $95 million,  the fee is paid to
            the  Adviser and the  Administrator  at the annual rate of 0.27% and
            0.13%,  respectively,  and on net assets  above  that  amount at the
            annual rate of 0.33% and 0.07%, respectively.

            Government  Fund - On net assets up to $60 million,  the fee is paid
            to the Adviser and the Administrator at the annual rate of 0.27% and
            0.13%,  respectively,  and on net assets  above  that  amount at the
            annual rate of 0.33% and 0.07%, respectively.

      The Adviser and the Administrator each agrees that the above fees shall be
reduced,  but not below  zero,  by an amount  equal to its  proportionate  share
(determined on the basis of the respective fees computed as described  above) of
the amount,  if any, by which the total  expenses of a Fund in any fiscal  year,
exclusive of taxes,  interest and brokerage fees, shall exceed the lesser of (i)
2.5% of the first $30  million of average  annual net assets of the Fund plus 2%
of the next $70 million of such assets and 1.5% of its average annual net assets
in excess of $100  million,  or (ii) 25% of the Fund's total  annual  investment
income. The payment of the above fees at the end of any month will be reduced or
postponed  so that at no time will there be any  accrued  but  unpaid  liability
under this  expense  limitation.  Advisory  and  administrative  fees in a given
fiscal year may be recouped prior to the end of such year if interest rates were
to increase.  Contractual  reduction of fees,  if any, is calculated on a fiscal
year basis.  No such  reduction  in fees was  required  for the six months ended
September 30, 2005.

      Under a Compliance Agreement with the Administrator,  the Administrator is
compensated for Chief Compliance Officer related services provided to enable the
Trust to comply with Rule 38a-1 of the Investment Company Act of 1940.

b)    DISTRIBUTION AND SERVICE FEES:

      Each Fund has adopted a  Distribution  Plan (the "Plan")  pursuant to Rule
12b-1  under the 1940 Act.  A part of the Plan  authorizes  payment  of  certain
distribution or service fees by the Service Shares Class of the respective Fund.
Such payments are made to "Designated Payees" - broker-dealers,  other financial
institutions and service providers who have entered into appropriate  agreements
with the  Distributor  and which have rendered  assistance  in the  distribution
and/or retention of the respective  Fund's Service Shares or in the servicing of
Service Share accounts.  The total payments under this part of a Fund's Plan may
not exceed 0.25% of its average annual assets  represented by Service Shares. No
such payments will be made by the Original Share Class.  Specific  details about
each Plan are more fully defined in the  Prospectus  and Statement of Additional
Information of the Trust.

      Under  a   Distribution   Agreement,   Aquila   Distributors,   Inc.  (the
"Distributor")  serves as the exclusive  distributor  of the Funds'  shares.  No
compensation or fees are paid to the Distributor for such share distribution.



c)    OTHER RELATED PARTY TRANSACTIONS:

      For the six months ended  September 30, 2005,  the following  amounts were
incurred for legal fees allocable to Hollyer Brady Barrett & Hines LLP,  counsel
to the Trust,  for legal  services in  conjunction  with the  respective  Fund's
ongoing  operations:  Cash Fund $21,579;  Tax-Free Fund $8,447;  Government Fund
$50,564. The Secretary of the Trust is a Partner of that firm.

4. GUARANTEES OF CERTAIN COMMERCIAL PAPER

      Various banks and other  institutions have issued  irrevocable  letters of
credit or guarantees for the benefit of the holders of certain commercial paper.
Payment at maturity of principal and interest of certain  commercial  paper held
by the Funds is supported by such letters of credit or guarantees.

5. EXPENSES

      The Funds  have  negotiated  an  expense  offset  arrangement  with  their
custodian,  wherein they receive  credit toward the reduction of custodian  fees
and other expenses  whenever there are uninvested cash balances.  The Statements
of Operations reflect the total expenses before any offset, the amount of offset
and the net expenses. It is the general intention of the Funds to invest, to the
extent  practicable,  some or all of cash  balances in  income-producing  assets
rather than leave cash on deposit.

6. PORTFOLIO ORIENTATION

      Since the Tax-Free Fund has a significant  portion of its  investments  in
obligations of issuers within Hawaii, it is subject to possible risks associated
with  economic,  political,  or legal  developments  or  industrial  or regional
matters  specifically  affecting Hawaii and whatever effects these may have upon
Hawaii issuers' ability to meet their obligations.

7. INCOME TAX INFORMATION AND DISTRIBUTIONS

      The Funds  declare  dividends  daily from net  investment  income and make
payments monthly in additional shares at the net asset value per share, in cash,
or a combination of both, at the shareholder's option.

      The tax  character of  distributions  during  fiscal 2005 and 2004 were as
follows:

      RECLASSIFICATION OF CAPITAL ACCOUNTS

      On the  statements  of assets  and  liabilities,  as a result  of  certain
differences in the computation of net investment income and net realized capital
gains under  federal  income tax rules and  regulations  versus  U.S.  generally
accepted  accounting  principles,  a reclassification  has been made to increase
(decrease)  undistributed net investment income  (distributions in excess of net
investment  income),  accumulated  net realized gain (loss) on  investments  and
additional paid-in capital for the Funds as follows:

                                                         Tax-Free     Government

                                           ---------     --------     ----------
Additional Paid-in Capital .............    $     --     $ 20,517      $     --
Undistributed net investment income ....          --      (20,517)           --

      These  reclassifications  are  primarily due to taxable  distributions  in
excess of net  investment  income  for the  Tax-Free  Fund.  Net  assets are not
affected by these changes.

8. CHANGE IN PRINCIPAL ACCOUNTANTS

      KPMG LLP was previously the principal  accountants for the Pacific Captial
Funds of Cash Assets Trust.  On July 27, 2005 KPMG LLP resigned as the principal
accountants  of the Trust  and Tait,  Weller  and Baker LLP was  engaged  as the
principal  accountants to audit the Fund's  financial  statements for the fiscal
year of 2006.  The  decision  was made by the  Audit  Committee  of the Board of
Trustees.

      The audit reports of KPMG LLP on the Funds' financial statements as of and
for the years ended  March 31, 2005 and 2004 did not contain an adverse  opinion
or disclaimer of opinion, nor were they qualified or modified as to uncertainty,
audit scope, or accounting principles.

      In connection with the audits of the two fiscal years ended March 31, 2005
and 2004 and the  subsequent  interim period through the opinion date of May 23,
2005  there  were no  reportable  events or  disagreements  with KPMG LLP on any
matter of accounting principles or practices, financial statement disclosure, or
auditing  scope  or  procedures,  which  disagreements  if not  resolved  to the
satisfaction  of KPMG LLP would have caused them to make reference in connection
with their opinion to the subject matter of the disagreements.

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

ANALYSIS OF EXPENSES (UNAUDITED) (CONTINUED)

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

      The table below provides information about hypothetical account values and
hypothetical  expenses  based on the actual expense ratio and an assumed rate of
return of 5.00% per year before  expenses,  which is not each of the  respective
Funds' 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 the  information  provided  in this  table to  compare  the
ongoing  costs of  investing  in the  Trust and other  mutual  funds.  To do so,
compare this 5.00% hypothetical example relating to the respective Fund with the
5.00%  hypothetical  examples  that appear in the  shareholder  reports of other
mutual funds.

ADDITIONAL INFORMATION (UNAUDITED)

RENEWAL OF INVESTMENT ADVISORY AGREEMENT

      Renewal  until June 30, 2006 of the  Investment  Advisory  Agreement  (the
"Advisory  Agreement")  for each fund  between  the Trust  and the  Adviser  was
approved by the Board of Trustees and the independent Trustees in June, 2005. At
a  meeting  called  and  held  for  that  purpose  at  which a  majority  of the
independent  Trustees  were  present in person,  the  following  materials  were
considered:

      o     Copies of the agreements to be renewed;

      o     A term sheet describing the material terms of the agreements;

      o     The Annual Report of the Trust for the year ended March 31, 2005;

      o     A Report by the Administrator  containing data about the performance
            of each of the  portfolios  and data about  their  respective  fees,
            expenses,  purchases and  redemptions  together with  comparisons of
            such data with similar data about other comparable funds, as well as
            data as to the  profitability of the Adviser and the  Administrator;
            and

      o     Quarterly  materials  reviewed  at  prior  meetings  on  each of the
            portfolio's performance, operations, portfolio and compliance.

      The Trustees considered each Advisory Agreement  separately.  The Trustees
reviewed materials relevant to, and considered, the factors set forth below, and
as to each agreement reached the conclusions described.

THE NATURE, EXTENT, AND QUALITY OF THE SERVICES PROVIDED BY THE ADVISER.

      The investment  objective of each of the Trust's  portfolios is to seek to
provide safety of principal  while  achieving as a high a level of liquidity and
of current income (and with respect to the Tax-Free Fund,  current income exempt
from Federal and Hawaii income taxes). To achieve these objectives,  the Adviser
has provided management of each fund's portfolio, as well as provided facilities
for credit analysis of each of the funds' portfolio securities.  With respect to
the Government Securities Fund, the Adviser has managed the investment portfolio
in order to achieve a Aaa/AAA  rating from both  Moody's  Investors  Service and
Standard and Poor's, respectively.

      The Board  considered that the Adviser had provided all services the Board
deemed necessary or appropriate,  including the specific services that the Board
has determined are required for the Trust,  given that its purpose is to provide
shareholders  with  safety of  principal  while  achieving  as a high a level of
liquidity and of current income.

      The Board  concluded  that a commendable  quality of services was provided
and that the Trust would be well served if they  continued.  Evaluation  of this
factor weighed in favor of renewal of the Advisory Agreements.

THE  INVESTMENT  PERFORMANCE  OF THE  TRUST  (AND  EACH OF ITS  PORTFOLIOS)  AND
ADVISER.

      The Board  determined it appropriate to consider each fund's  performance.
For the fiscal  year ended March 31,  2005 each  fund's  average  annual rate of
return was:

      Cash Fund (Original Shares): 1.36%
      Cash Fund (Service Shares): 1.11%
      Tax-Free Fund (Original Shares): 1.16%
      Tax-Free Fund (Service Shares): 0.90%
      Government Securities Fund (Original Shares): 1.41%
      Government Securities Fund (Service Shares): 1.16%



      The Board reviewed each aspect of each fund's performance and compared its
performance  with that of their  respective  benchmarks.  It was noted  that the
materials  provided by the Administrator  indicated that compared to each fund's
respective benchmark, the Trust's portfolios had investment performance that was
either  comparable  to or  favorable  for one-,  five- and  ten-year  periods as
compared with the benchmark. The Board considered these results to be consistent
with the purposes of each of the Trust's portfolios.

      The Board  concluded that the performance of each fund, in light of market
conditions,  was  satisfactory.  Evaluation  of  this  factor  indicated  to the
Trustees that renewal of the Advisory Agreements would be appropriate.

THE COSTS OF THE  SERVICES  TO BE  PROVIDED  AND  PROFITS TO BE  REALIZED BY THE
ADVISER AND ITS AFFILIATES FROM THE RELATIONSHIP WITH THE TRUST (AND EACH OF ITS
PORTFOLIOS).

      The information provided in connection with renewal contained expense data
for each fund and its  major  local  competitor  as well as data for each of the
funds with respect to their  respective  peer groups,  including  data for money
market  funds  of a  comparable  asset  size.  The  materials  also  showed  the
profitability to the Adviser of its services to the Trust.

      The Board  compared  the expense and fee data with  respect to each of the
portfolios  to similar data about other funds that it found to be relevant.  The
Board  concluded  that the expenses of the each of the  portfolios  and the fees
paid were similar to and were  reasonable as compared to those being paid by its
respective local competitor and other money market funds nationwide.

      The Board considered that the foregoing  indicated the  appropriateness of
the  costs of the  services  to the  Trust,  which  was being  well  managed  as
indicated by the factors considered previously.

      The Board further  concluded that the profitability to the Adviser did not
argue against approval of the fees to be paid under each Advisory Agreement.

THE EXTENT TO WHICH  ECONOMIES OF SCALE WOULD BE REALIZED AS THE TRUST,  AND ITS
PORTFOLIOS, GROWS.

      Data  provided to the  Trustees  showed that the asset size of each of the
portfolios  had  been  generally  increasing  in  recent  years.  However,  they
concluded that the uncertain  interest rate environment  might make it difficult
to achieve  substantial  growth in assets in the near future.  The Trustees also
noted that the materials indicated that the each portfolio's fees were generally
comparable to those of its peers,  including those with breakpoints.  Evaluation
of this factor  indicated  to the Board that the Advisory  Agreements  should be
renewed without addition of breakpoints at this time.

BENEFITS  DERIVED OR TO BE DERIVED BY THE  ADVISER AND ITS  AFFILIATES  FROM THE
RELATIONSHIP WITH THE TRUST (AND EACH OF ITS PORTFOLIOS).

      The Board observed that, as is generally true of most fund complexes,  the
Adviser and its affiliates,  by providing services to a number of funds or other
investment  clients including the Trust's three portfolios,  were able to spread
costs as they would  otherwise  be unable to do. The Board noted that while that
produces  efficiencies  and  increased  profitability  for the  Adviser  and its
affiliates,  it also makes their services  available to the three  portfolios of
the Trust at favorable levels of quality and cost which are more advantageous to
the Trust's portfolios than would otherwise have been possible.
