                            THE PACIFIC CAPITAL FUNDS
                              OF CASH ASSETS TRUST
                          NOTES TO FINANCIAL STATEMENTS
                                   (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  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 Trust. 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 Funds.  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.

      For the period April 1, 2002  through  September  30,  2004,  advisory and
administrative  fees have been  contractually  reduced (see ii above) due to the
low interest rate environment. For the six months ended September 30, 2004:

            Cash Fund incurred advisory and administration  fees of $744,960 and
            $310,739;  due to the expense limitation,  such fees were reduced by
            $491,568 and $205,044, respectively.

            Tax-Free Fund incurred advisory and administration  fees of $246,637
            and $86,955;  due to the expense limitation,  such fees were reduced
            by $191,909 and $67,660, respectively.

            Government  Fund  incurred  advisory  and  administration   fees  of
            $1,381,382 and $314,897;  due to the expense  limitation,  such fees
            were reduced by $997,133 and $227,304, respectively.

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 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 Funds'  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 Funds.

      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, 2004,  the following  amounts were
accrued for legal fees:  Cash Fund $16,096;  Tax-Free  Fund $11,394;  Government
Fund $33,769. Of these amounts, $14,767, $10,997 and $32,085, respectively, were
allocable to Hollyer Brady Barrett  &Hines LLP,  counsel to the Fund,  for legal
services in conjunction with the Fund's ongoing operations. The Secretary of the
Fund is a Partner of Hollyer Brady Barrett & Hines LLP.

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  paid  during  2004 and 2003 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 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
                                         CASH FUND        FUND          FUND
                                         ----------    ----------    ----------
Paid-in Capital .......................  $       --    $  (37,136)   $       --
Undistributed net investment income ...       1,319        37,174           421
Accumulated net realized gain (loss) ..      (1,319)          (38)         (421)

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

ANALYSIS OF EXPENSES (UNAUDITED)

      As a  shareholder  of the Trust,  you may incur ongoing  costs,  including
management fees; distribution (12b-1) fees; and other Trust expenses. The tables
below are intended to help you  understand  your  ongoing  costs (in dollars) of
investing  in the Trust and to compare  these  costs with the  ongoing  costs of
investing in other mutual funds.

      The tables below are based on an investment of $1,000 invested on April 1,
2004 and held for the six months ended September 30, 2004.

ACTUAL EXPENSES

      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".

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 the  Trust'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 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 Trust with the 5.00% hypothetical  examples
that appear in the shareholder reports of other mutual funds.
