Dear Investor:

      It gives us  considerable  pleasure to present  the Annual  Report for The
Pacific  Capital  Funds of Cash Assets Trust for the fiscal year ended March 31,
2007.

      The enclosed  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. The Trust was
specifically created to meet the short-term investment needs of Hawaii investors
and others.

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

SLOWING ECONOMY

      During the current  report  period,  the U.S.  economy  continued to grow,
albeit at a somewhat  slower  pace.  It would  appear that the  Federal  Reserve
Board's (the "Fed") two-year  campaign of raising  short-term  interest rates to
slow the  economy  may have  taken  hold.  Recall,  when the Fed  began  raising
short-term  interest rates in March 2004, the Federal Fund's rate - the interest
rate member banks charge each other for overnight loans and the primary tool for
influencing  economic  activity - was 1%, a historically  low rate  environment.
After 17 consecutive  interest rate hikes of 0.25% each ending in June 2006, the
Fed Fund's rate was 5.25%. The Fed's action along with a weakening manufacturing
sector,  slumping  housing  market and high oil prices have  contributed  to the
slowing of the U.S. economy to its lowest level in four years.

      With  mounting  evidence of a slowing  economy and mixed signs of a rising
level  of  inflation,   the  Fed's  monetary  policy  has  remained  steady  and
noncommittal  about the  outlook  for  future  rate  action.  Economic  analysts
continue to debate the direction of the economy.  On the one hand, the Fed could
orchestrate an economic  "soft landing" with positive  growth and low inflation.
On the other hand, should the economy surprise and show signs of heating up with
inflation rising, the Fed may choose to raise short-term interest rates.

A WATCHFUL EYE

      Rest assured the Trust's  investment  management  team will seek to keep a
watchful  eye on economic  developments,  financial  markets and  interest  rate
movements, as they steer the course of


                        NOT A PART OF THE ANNUAL REPORT


each of the Trust's portfolios. In managing the portfolios,  the team intends to
continue  to be alert to market  opportunities  as it seeks to  produce a higher
return competitive with other short-term alternatives.

      You can be  assured  that in our  desire to  achieve  higher  returns  for
investors,  the Asset  Management  Group of the Bank of Hawaii will  continually
seek to manage investments in a cautious, but aggressive, manner. Safety of your
cash  reserves  remains  of utmost  concern  to us.  We  believe  that  there is
absolutely  no  substitute  for strict  adherence to high quality of  securities
which possess minimum credit risk.

      On behalf of the Board of Trustees and the Trust's management,  thank your
for your  continued  confidence and trust you have placed in us. We look forward
to serving your investment needs for many years to come.

                                   Sincerely,


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

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of
The Pacific Capital Funds of Cash Assets Trust:

      We have  audited the  accompanying  statement  of assets and  liabilities,
including the  schedules of  investments,  of The Pacific  Capital Funds of Cash
Assets Trust (the  "Trust")  (comprised  of Pacific  Capital Cash Assets  Trust,
Pacific Capital Tax-Free Cash Assets Trust, and Pacific Capital U.S.  Government
Securities  Cash  Assets  Trust)  (the  "Funds"),  as of March 31,  2007 and the
related statements of operations for the year then ended, and the changes in net
assets and the financial highlights for each of the two years in the period then
ended.   These   financial   statements   and  financial   highlights   are  the
responsibility of the Trust's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits. The financial  highlights for each of the years in the three year period
ended March 31, 2005 have been audited by other auditors, whose report dated May
23, 2005 expressed an unqualified opinion on such financial highlights.

      We conducted  our audits in  accordance  with the  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform our audits to obtain reasonable  assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have,  nor were we engaged to perform,  an audit of
the Trust's  internal  control over  financial  reporting.  Our audits  included
consideration  of  internal  control  over  financial  reporting  as a basis for
designing audit  procedures that are appropriate in the  circumstances,  but not
for the purpose of  expressing  an opinion on the  effectiveness  of the Trust's
internal  control  over  financial  reporting.  Accordingly,  we express no such
opinion. An audit also includes examining,  on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities  owned as of March 31, 2007, by  correspondence  with
the custodian  and brokers.  An audit also  includes  assessing  the  accounting
principles  used  and  significant  estimates  made  by  management,  as well as
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly,  in all material  respects,  the financial  position of
each of the Funds  comprising  the Trust as of March 31,  2007,  the  results of
their  operations  for the year then ended,  and the changes in their net assets
and the financial highlights for each of the two years in the period then ended,
in conformity with accounting principles generally accepted in the United States
of America.

                            THE PACIFIC CAPITAL FUNDS
                              OF CASH ASSETS TRUST
                          NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 2007

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 the 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)    NEW  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 requires 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
      be recorded as a tax benefit or expense in the current  year.  Adoption of
      FIN 48 is required to be  implemented no later than September 30, 2007 and
      is to be  applied  to all open tax years as of that  date.  At this  time,
      management  does not  believe  the  adoption  of FIN 48 will result in any
      material impact on the Trust's financial statements.

      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 year ended March 31,
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 year ended March 31, 2007, 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 $43,585; Tax-Free Fund $28,148; Government Fund $58,030. The Secretary
of the Trust is a Partner at 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

matters  specifically  affecting Hawaii and whatever effects these may have upon
Hawaii issuers' ability to meet their obligations.

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 October 1,
2006 and held for the six months ended March 31, 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.

ITEM 2.  CODE OF ETHICS.

(a) As of March 31, 2007 (the end of the reporting period) the
Trust has adopted a code of ethics that applies to the Trust's
principal executive officer(s)and principal financial officer(s)
and persons performing similar functions ("Covered Officers") as
defined in the Aquila Group of Funds Code of Ethics for Principal
Executive and Senior Financial Officers under Section 406 of the
Sarbanes-Oxley Act of 2002;

(f)(1) Pursuant to Item 10(a)(1), a copy of the Trust's Code of
 Ethics that applies to the Trust's principal executive officer(s)
 and principal financial officer(s) and persons performing similar
functions is included as an exhibit to its annual report on this
Form N-CSR;

(f)(2)  The text of the Trust's Code of Ethics that applies to the
Trust's principal executive officer(s) and principal financial
officer(s) and persons performing similar functions has been
posted on its Internet website which can be found at the Trust's
Internet address at aquilafunds.com.


ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

(a)(1)(ii) The Board of Trustees of the Fund has determined that
it does not have at least one audit committee financial expert
serving on its audit committee.  The Fund does not have such a
 person serving on the audit committee because none of the persons
 currently serving as Trustees happens to have the technical
accounting and auditing expertise included in the definition of
"audit committee financial expert" recently adopted by the Securities
and Exchange Commission in connection with this Form N-CSR, and the
Board has not heretofore deemed it necessary to seek such a person
for election to the Board.

The primary mission of the Board, which is that of oversight over
the operations and affairs of the Fund, confronts the Trustees with
 a wide and expanding range of issues and responsibilities. The
 Trustees believe that, accordingly, it is essential that the Board's
membership consist of persons with as extensive experience as possible
in fulfilling the duties and responsibilities of mutual fund directors
and audit committee members and, ideally, with extensive experience
 and background relating to the economic and financial sectors and
securities in which the Fund invests, including exposure to the
financial and accounting matters commonly encountered with respect
to those sectors and securities.  The Board believes that its current
 membership satisfies those criteria.  It recognizes that it would
also be helpful to have a member with the relatively focused accounting
and auditing expertise reflected in the applicable definition of
"audit committee financial expert," just as additional members with
 similarly focused technical expertise in other areas relevant to
the Fund's operations and affairs would also contribute added value.
However, the Board believes that the Fund is better served, and its
assets better employed, by a policy of hiring experts in various
areas, including the specialized area of technical accounting and
auditing matters, if and as the Board identifies the need, rather
than by seeking to expand its numbers by adding technical experts
in the areas constituting its domain of responsibility.  The Fund's
Audit Committee Charter explicitly authorizes the Committee to
retain such experts as it deems necessary in fulfilling its duties
under the Charter.
