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,
2007.

      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 their two classes of shares: Original Shares and Service Shares.

                      ************************************

      The  current  six-month  reporting  period  was  marked by the  widespread
turbulence in the financial markets with the impact felt across a broad range of
asset  classes.  The  financial  markets  became  more  volatile  in reaction to
increasing  defaults on sub-prime  mortgages,  or loans with weaker underwriting
standards.  The problems  and  concerns  surrounding  sub-prime  mortgage  loans
rippled  through  the  fixed-income  market,   including  short-term  investment
instruments which constitute a large portion of money market securities.

      As the  liquidity  crisis in the  financial  markets  continued  to unfold
during the summer  months,  the Federal  Reserve (the "Fed") voted to change the
course  of its  monetary  policy.  Citing a need to  induce  liquidity  into the
banking system and to possibly  curtail any threat of a slowdown in the economy,
the Fed lowered the target on the Federal Funds rate to 4.75%. 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,  a
reduction in interest rates usually means lower borrowing cost for consumers and
businesses, resulting in an increase in economic activity. The action by the Fed
was a bold attempt to restore  investor  confidence  and a clear signal that the
central bank viewed the turbulence and  disruptions of the past couple of months
as too dangerous to ignore.

      The move by the Fed was also the first rate  reduction of any kind in four
years,  the steepest in nearly five years and its most abrupt reversal of course
since January 2001, when Fed policy makers sharply reduced  interest rates at an
unscheduled emergency meeting just before the last recession.

                      NOT A PART OF THE SEMI-ANNUAL REPORT



      Over the past couple of years,  there has been a fundamental change in the
way people look at their  investments.  Investors  will always want  competitive
returns, yet, with the recent problem areas that have developed in the financial
markets, the words most often heard these days are, "How safe is my investment?"
This is  especially  true for  investors'  cash  reserves.  As you have  read in
previous  shareholder  report letters,  we have used this  opportunity to remind
investors  that safety of  principal  is first and  foremost in the eyes of your
Board of Trustees,  Investment Adviser and Administrator when managing your cash
reserves.  Each of the Trust's investment portfolios has successfully  weathered
the recent financial crisis by adhering to each  portfolios'  stated  objective.
Rest assured,  your  Investment  Adviser and its portfolio  management  team has
always  sought to ensure  that no undue  risks are taken in order to seek higher
yield.

      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.

      As always,  we again wish to express our  appreciation  for the confidence
you have shown by your  investment  in the Pacific  Capital Funds of Cash Assets
Trust.  We can  assure you that we will  consistently  do our best to merit your
continued level of trust.

Sincerely,


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

                              OF CASH ASSETS TRUST
                         NOTES TO FINANCIAL STATEMENTS
                         SEPTEMBER 30, 2007 (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 accounting principles generally accepted in the United States of
America.

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 each Fund's  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  accounting  principles  generally  accepted in the United  States of
      America 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.

h)    RECLASSIFICATION  OF CAPITAL  ACCOUNTS:  Accounting  principles  generally
      accepted in the United States of America  require that certain  components
      of net assets relating to permanent  differences be  reclassified  between
      financial and tax reporting. These reclassifications have no effect on net
      assets or net asset value per share. On March 31, 2007, a reclassification
      was  made to  increase  (decrease)  undistributed  net  investment  income
      (distributions  in excess of net investment  income) and  accumulated  net
      realized gain (loss) on investments for the Funds as follows:

                                                           TAX-FREE   GOVERNMENT
                                                CASH FUND    FUND       FUND
                                                ---------  --------   ----------
        Accumulated net realized gain (loss)
          on investements ....................  $      --  $ (10,337) $      --
        Undistributed net investment income...         --     10,337         --

      These reclassifications are primarily due to dividend redesignations. Net
      assets were not affected by these changes.

i)    ACCOUNTING   PRONOUNCEMENTS:   In  July  2006,  the  Financial  Accounting
      Standards Board ("FASB") released FASB  Interpretation  No. 48 "Accounting
      for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides  guidance for
      how uncertain tax positions should be recognized, measured,



      presented and disclosed in the financial  statements.  FIN 48 required the
      evaluation of tax positions taken or expected to be taken in the course of
      preparing  the Trust's tax returns to determine  whether the tax positions
      are  "more-likely-than-not"  of  being  sustained  by the  applicable  tax
      authority.  Tax  positions  not  deemed  to meet the  more-likely-than-not
      threshold  would  have been  recorded  as a tax  benefit or expense in the
      current year. FIN 48 was effective for the Trust on September 28, 2007 and
      there were no  uncertain  tax  positions  to be  reflected  in the Trust's
      financial statements at September 30, 2007.

      In  September  2006,  FASB issued  FASB  Statement  No.  157,  "Fair Value
      Measurement"  ("SFAS  157"),  which  defines  fair  value,  establishes  a
      framework for measuring  fair value,  and expands  disclosures  about fair
      value measurements. SFAS 157 is effective for fiscal years beginning after
      November 15, 2007,  and interim  periods  within those fiscal  years.  The
      Trust  believes  adoption of SFAS 157 will have no material  impact on the
      Trust's financial statements.

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  Administration  Agreements 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, 2007.

      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   Distribution   Agreements,   Aquila   Distributors,    Inc.   (the
"Distributor")  serves as the exclusive  distributor of each Fund's  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, 2007,  the following  amounts were
incurred for legal fees allocable to Hollyer Brady Barrett & Hines LLP ("Hollyer
Brady")  and its  successor,  Butzel  Long PC,  counsel to the Trust,  for legal
services in conjunction with the respective Fund's ongoing operations: Cash Fund
$15,711;  Tax-Free Fund $3,834;  Government  Fund $30,905.  The Secretary of the
Trust was a partner at Hollyer Brady and is a shareholder of its successor.



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.

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 2007 and 2006 were as follows:

ANALYSIS OF EXPENSES (UNAUDITED)

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

      The table below is based on an investment  of $1,000  invested on April 1,
2007 and held for the six months ended September 30, 2007.

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 actual return of each
of the respective Funds. 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  portfolios  of 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.

RENEWAL OF INVESTMENT ADVISORY AGREEMENT

      Renewal  until June 30, 2008 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, 2007. 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, 2007;

      o     A report,  prepared by the Adviser and Administrator and provided to
            the  Trustees in advance of the meeting  for the  Trustees'  review,
            containing  data about the performance of each of the portfolios and
            data  about  their   respective   fees,   expenses,   purchases  and
            redemptions of capital stock 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 portfolio's
            performance, operations, portfolio and compliance.

      The Trustees considered each Advisory Agreement  separately.  The Trustees
reviewed materials relevant to, and considered, the following factors as to each
agreement and 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 the  services  provided  were  appropriate  and
satisfactory  and  that  the  Trust  would  be well  served  if they  continued.
Evaluation of this factor weighed in favor of renewal of the Advisory Agreement.

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

      The Board reviewed each aspect of each fund's performance and compared its
performance  with  that of its  respective  benchmark.  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 each Advisory Agreement 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
local competitor and by 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 each  Advisory  Agreement  should be
renewed without additional 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.
