                            TAX-FREE FUND OF COLORADO

                          "TAX-FREE IN BLACK AND WHITE"

                                                                  February, 2007

Dear Fellow Shareholder:

      We have all seen and heard the words  "tax-free"  over and over in various
contexts. In fact, the name of the Fund contains the words "tax-free." But, what
does that really mean to you in black and white?

      As you know,  you have to pay  federal,  state,  and/or local taxes on the
dividends  distributed to you by a taxable mutual fund.  Thus, a bond fund which
invests in tax-free  municipal  bonds,  such as Tax-Free  Fund of Colorado,  may
actually  generate  more net  dividend  income  than a taxable  bond fund with a
higher stated yield.

      How is this possible? Let's use a simple example.

      Suppose you invest $10,000 in a hypothetical  TAX-FREE municipal bond fund
with a yield of 4%, paying  dividends that are EXEMPT FROM FEDERAL INCOME TAXES,
and you also invest $10,000 in a hypothetical  TAXABLE bond fund with a yield of
5.5%,  paying dividends that are TAXABLE AT THE FEDERAL LEVEL. The example below
shows the outcome for an investor in the 33% federal income tax bracket.  As you
can see, your investment in the tax-free bond municipal fund would have ended up
with more after-tax income even though the fund's yield was lower.

                                  [BAR CHART]

Taxable Bond Fund Yielding 5.5%           $181.50             $368.50
                                       Tax Rate 33%

      To help you compare  taxable bond funds  versus  tax-free  municipal  bond
funds, a taxable-equivalent  yield is often used. The  taxable-equivalent  yield
provides  you with the rate that a taxable bond fund would have to yield to give
you the same after-tax  yield as a tax-free  municipal bond fund. (You should be
aware that the calculation does not take into account the impact of state income
taxes,  or any  alternative  minimum  taxes,  to  which  some  investors  may be
subject.)

                        NOT A PART OF THE ANNUAL REPORT



      In its simplest terms,

- --------------------------------------------------------------------------------
Yield of tax-free municipal bond fund
- --------------------------------------      =      Your taxable-equivalent yield
1.00 - your federal income tax rate
- --------------------------------------------------------------------------------

      Using the above  tax-free  example of a 4% yield and a federal tax bracket
of 33%, the calculation would be as follows:

- --------------------------------------------------------------------------------
    4
- ------------                                =      5.97%
1.00 - 0.33
- --------------------------------------------------------------------------------

      In other words, a tax-free investment of 4.00% and a taxable investment of
5.97% would provide the same yield after taxes.

Interest                                   $      400              $      597
33% Federal income tax                     $        0              $   197.01
Net return                                 $      400              $   399.99
Yield on investment after federal taxes           4.0%                    4.0%

      You should be aware that dividends paid by tax-free  municipal bond funds,
such as Tax-Free Fund of Colorado, are often also exempt from state and/or local
taxes. FACTORING IN THE EXEMPTION AT THE STATE AND/OR LOCAL LEVEL WOULD HAVE THE
EFFECT OF INCREASING THE TAXABLE EQUIVALENT YIELD EVEN FURTHER.

      So, the next time that you see the  phrase  "tax-free,"  remember  that in
black and white, it oftentimes means more money into your pocket.

                                   Sincerely,


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

For certain investors, some dividends of your Fund may be subject to Federal and
State taxes. These hypothetical  examples are not intended to predict or project
investment performance.  Your own results will vary. State and local taxes, fees
and expenses, if any, are not taken into account.

                              MANAGEMENT DISCUSSION

2006 REVIEW

      The  Federal  Reserve  Board (the  "Fed")  appeared to reach their goal of
equilibrium  during 2006. In the first six months of the year, the Fed continued
to raise the benchmark  Federal Funds rate by an additional 1.0% to 5.25%.  This
tight money  policy that the Fed pursued for the past few years was  designed to
maintain a low inflationary  environment.  As 2006  progressed,  it became clear
that the  residential  housing market was  experiencing a  retrenchment,  energy
prices  had  leveled  off and  actually  began  to  decline  and the  underlying
inflation rate was in the moderate 2.5% range.  These economic  factors  allowed
the Fed to break its string of 17 consecutive increases in short-term rates.

      The balancing factor to slower economic growth and tame inflation  numbers
was the  strength in the labor  markets.  U.S.  employers  added  about  153,000
workers per month during 2006.  The  unemployment  rate has dropped to 4.5% from
around  5.0%  a  year  ago.   While  a  strong  job  market  can  be  considered
inflationary,  increased worker productivity appears to have kept wage inflation
in check.

      The standoff between moderate  economic  activity and strong labor markets
has allowed the Federal Reserve to hold  short-term  rates steady for the last 6
months of the year.  Interest rates on U.S.  Treasury  securities  rose slightly
during  2006.  The  2-year  rate rose from  4.37% to 4.80%  while 10 and 20 year
yields only increased by about 0.30% to 4.72% and 4.91%, respectively. The yield
curve is now  inverted  which  means  that  short-term  rates  are  higher  than
long-term rates. Historically this condition has prefaced a slowdown in economic
activity.  If short-term  rates  continue to rise more than  long-term  rates, a
recession becomes more likely.

      The Colorado  economy also  continues  its  recovery.  The Office of State
Planning and Budgeting  reports that  unemployment has dropped to 4.5% from 5.0%
last year.  They predict that  personal  income growth will average 7.0% in 2006
and 6.2% in 2007. Retail sales are forecast to increase 5.6% and consumer prices
rose about 3.5% during  2006.  The major  weakness in the  Colorado  economy was
residential  real estate.  Colorado  experienced one of the highest  foreclosure
rates in the  nation.  Public  trustees  in the six  county  Denver  metro  area
reported more than 19,000 foreclosures initiated in 2006, a record amount. A few
of the many causes for this  lackluster  performance  are  over-building,  loose
lending practices and over-stretched  consumers.  The weakness in housing values
was  concentrated in Weld,  Adams,  Larimer,  El Paso and Pueblo  counties.  The
strongest real estate markets in Colorado were in the mountain  resort  counties
of  Pitkin,  Eagle and  Garfield  where  appreciation  rates  were in the double
digits. We are monitoring real estate values

very closely around the state as that is an important  factor in determining the
creditworthiness of many municipal entities.

      New  issuance in the  Colorado  municipal  bond market was robust in 2006.
Total new bond  sales were up 21% to $8.6  billion  for the year.  In  November,
voters approved approximately $1 billion in school bonds to be issued throughout
the state.  The  Regional  Transportation  District  issued $600 million for the
Fastracks  project,  an expansion  of light rail in the metro area,  in October.
This  project has  approval for $3.5 billion in total debt over the next several
years.  Special  District  financings,  which are  smaller  local  issuers  with
specific purposes, totaled $890 million for the year.

      The  investment  strategy  for  Tax-Free  Fund of  Colorado  continues  to
emphasize risk  reduction.  In our 2006 strategy  outlook,  we suggested that we
might reduce our holdings in shorter maturities and add to bonds in the 13 to 15
year range in the event that  short-term  interest  rates began to decline.  The
market  did not  cooperate  with  this  outlook.  Interest  rates on 1 to 5 year
municipals  rose  0.15% to 0.40%  while  rates on 10 to 20 year  bonds  actually
declined  by 0.10% to 0.20%.  This market  behavior  shows that  investors  were
willing to take more  interest rate risk by investing in longer  maturity  bonds
and were willing to accept lower  returns to do so! We do not believe that it is
prudent to buy longer bonds until we are earning yields that are higher than the
shorter  bonds we own.  We were also  prepared  to  purchase  bonds  with  lower
investment  grade ratings if those yields improved  relative to AAA rated bonds.
The relationship between AAA and A rated bonds remained largely unchanged during
the year.  An investor  could improve yield by about 0.30% by dropping down to A
rated bonds.  Again,  we do not believe this strategy would have provided enough
increased return for the additional risk added to the portfolio.

      The average  maturity on December 31, 2006 was 7.0 years, and 95.1% of the
portfolio  was  invested in AAA and AA rated  securities.  The total  return for
Class A  investors  based on the net asset  value was 3.11% in 2006.  The double
tax-exempt  dividend yield for Class A shares averaged  approximately  3.87% for
the year.

2007 STRATEGY

      As we approach our 20th  anniversary in May 2007, we think it is important
to review our  mission.  Tax-Free  Fund of  Colorado  was formed in 1987 after a
period of extremely  volatile  interest  rates.  Bond investors had  experienced
double  digit  negative  returns for the first time and were not too happy about
it. We decided at the outset of the Fund that we wanted to provide an investment
product that would seek to mitigate  the impact of dramatic  changes in interest
rates while providing steady double tax-exempt income. The two investment tenets
at  the  core  of  this   philosophy   are   intermediate   maturity  bonds  and
investment-grade  credit quality.  Historically,  intermediate maturity bonds do
not experience as much price  fluctuation as longer bonds with a given change in
interest rates.  Investment-grade bonds have also retained their value better in
hostile  market  conditions  such as recessions  and periods of rising  interest
rates.  In the past few years we have  experienced  the unusual  circumstance of
rising  short-term  rates and declining  long-term  rates. We have also seen the
yields on non-rated and lower rated investment grade bonds drop more than yields
of the highest



MANAGEMENT DISCUSSION OF FUND PERFORMANCE (CONTINUED)

quality  bonds.   These  temporary  market   conditions  have  not  favored  the
conservative  investment  strategy  of the Fund.  It has been very  tempting  to
increase  the yield of the Fund by adding  more  interest  rate risk from longer
bonds and more credit risk from lower rated bonds. We have chosen,  however, not
to add the additional risk to our portfolio  because we believe that these risks
are not priced  appropriately.  We also  believe  that it is important to remain
true to our original  mission of safety and  stability.  We may  sacrifice  some
yield in the short  term in order to  protect  the  value of our  shares in more
difficult  market  conditions.  Our  prospectus  allows us the  latitude to make
portfolio  changes to improve yield and we will intend to do so as opportunities
present  themselves.  At the present time, we plan to focus new purchases in the
14 to 17 year maturity  range as that is where the market offers the best value.
We will  monitor the  differences  between  high-grade  and lower  rated  credit
sectors  and seek to  emphasize  those  securities  with the best risk  adjusted
returns. We believe that our current portfolio of shorter maturity, high coupon,
high  quality  bonds is very  liquid  and  should,  therefore,  allow us to make
changes as the market  allows.  Our goal is to provide a safe,  stable  tax-free
income stream with low share price volatility.

      Thank you for your investment in Tax-Free Fund of Colorado.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of
Tax-Free Fund of Colorado:

      We have  audited the  accompanying  statement  of assets and  liabilities,
including  the  schedule  of  investments,  of  Tax-Free  Fund of Colorado as of
December  31, 2006 and the related  statement  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 Fund'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 December 31, 2004 have been audited by other  auditors,  whose
report  dated  February  18,  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 the audit to obtain  reasonable  assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Fund is not  required to have,  nor were we engaged to perform,  an audit of
the Fund'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 Fund'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 December 31, 2006, 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
Tax-Free Fund of Colorado as of December 31, 2006, the results of its operations
for the year then  ended,  and the  changes in its 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.

                            TAX-FREE FUND OF COLORADO
                          NOTES TO FINANCIAL STATEMENTS
                                DECEMBER 31, 2006

1. ORGANIZATION

      Tax-Free  Fund of  Colorado  (the  "Fund"),  a  non-diversified,  open-end
investment company, was organized in February,  1987 as a Massachusetts business
trust and commenced  operations on May 21, 1987. The Fund is authorized to issue
an  unlimited  number of shares  and,  since its  inception  to April 30,  1996,
offered  only one class of shares.  On that date,  the Fund began  offering  two
additional classes of shares, Class C and Class Y shares. All shares outstanding
prior  to that  date  were  designated  as Class A  shares  and are sold  with a
front-payment  sales charge and bear an annual  distribution fee. Class C shares
are sold with a  level-payment  sales charge with no payment at time of purchase
but level service and  distribution  fees from date of purchase through a period
of six years thereafter. A contingent deferred sales charge of 1% is assessed to
any Class C  shareholder  who redeems  shares of this Class within one year from
the date of purchase.  Class C Shares,  together with a pro-rata  portion of all
Class  C  Shares   acquired   through   reinvestment   of  dividends  and  other
distributions paid in additional Class C Shares,  automatically convert to Class
A Shares  after 6 years.  The Class Y shares are only  offered  to  institutions
acting for an investor in a fiduciary,  advisory,  agency,  custodian or similar
capacity and are not offered  directly to retail  investors.  Class Y shares are
sold at net asset value without any sales charge,  redemption  fees,  contingent
deferred  sales charge or  distribution  or service fees. On April 30, 1998, the
Fund  established  Class I shares,  which  are  offered  and sold  only  through
financial intermediaries and are not offered directly to retail investors. Class
I Shares are sold at net asset value without any sales charge,  redemption fees,
or contingent  deferred sales charge.  Class I Shares carry a  distribution  and
service  fee.  As of the report  date no Class I Shares  were  outstanding.  All
classes of shares  represent  interests in the same portfolio of investments and
are identical as to rights and  privileges but differ with respect to the effect
of sales  charges,  the  distribution  and/or  service fees borne by each class,
expenses  specific to each class,  voting  rights on matters  affecting a single
class and the exchange privileges of each class.

2. SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant  accounting policies followed by
the Fund in the  preparation  of its financial  statements.  The policies are in
conformity with accounting principles generally accepted in the United States of
America for investment companies.

a)    PORTFOLIO VALUATION:  Municipal securities which have remaining maturities
      of more than 60 days are valued at fair value each business day based upon
      information provided by a nationally prominent independent pricing service
      and periodically  verified through other pricing services.  In the case of
      securities for which market quotations are readily  available,  securities
      are valued by the pricing service at the mean of bid and asked quotations.
      If market  quotations  or a  valuation  from the  pricing  service  is not
      readily available, the security is valued at fair value determined in



      good  faith  under  procedures   established  by  and  under  the  general
      supervision of the Board of Trustees.  Securities  which mature in 60 days
      or less are valued at amortized cost if their term to maturity at purchase
      is 60 days or less,  or by amortizing  their  unrealized  appreciation  or
      depreciation on the 61st day prior to maturity,  if their term to maturity
      at purchase exceeds 60 days.

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  premium  and  accretion  of  original  issue and  market
      discount.

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

d)    MULTIPLE   CLASS   ALLOCATIONS:   All   income,   expenses   (other   than
      class-specific  expenses), and realized and unrealized gains or losses are
      allocated  daily to each class of shares  based on the relative net assets
      of each class.  Class-specific  expenses,  which include  distribution and
      service  fees and any other items that are  specifically  attributed  to a
      particular class, are charged directly to such class.

e)    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.

f)    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  December  31,  2006 the Fund
      increased  undistributed  net investment  income by $610,262 and decreased
      additional paid-in capital by $610,262 due primarily to differing book/tax
      treatment of distributions and bond amortization.

g)    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
      Fund'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 June 29,  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  Fund'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 Fund
      believes  adoption of SFAS 157 will have no material  impact on the Fund's
      financial statements.

Sub-Adviser  are more fully  defined in the Fund's  Prospectus  and Statement of
Additional Information.

b) DISTRIBUTION AND SERVICE FEES:

      The Fund has adopted a  Distribution  Plan (the  "Plan")  pursuant to Rule
12b-1 (the "Rule") under the Investment  Company Act of 1940.  Under one part of
the Plan, with respect to Class A Shares, the Fund is authorized to make service
fee payments to broker-dealers or others  ("Qualified  Recipients")  selected by
Aquila Distributors,  Inc. (the "Distributor"),  including,  but not limited to,
any principal  underwriter of the Fund,  with which the  Distributor has entered
into  written  agreements  contemplated  by the Rule  and  which  have  rendered
assistance  in the  distribution  and/or  retention  of  the  Fund's  shares  or
servicing of  shareholder  accounts.  The Fund  currently  makes payment of this
distribution  fee at the  annual  rate of 0.05 of 1% of the Fund's  average  net
assets  represented  by Class A Shares.  The Board of Trustees and  shareholders
approved an  amendment to the Fund's  Distribution  Plan  applicable  to Class A
Shares which  permits the Fund to make service fee payments at the rate of up to
0.15 of 1% on the entire net assets  represented by Class A Shares. For the year
ended  December  31,  2006,  distribution  fees on  Class A Shares  amounted  to
$103,635 of which the Distributor retained $3,496.

      Under  another part of the Plan,  the Fund is  authorized to make payments
with  respect to Class C Shares to  Qualified  Recipients  which  have  rendered
assistance in the distribution  and/or retention of the Fund's Class C shares or
servicing of shareholder accounts. These payments are made at the annual rate of
0.75% of the Fund's average net assets represented by Class C Shares and for the
year ended  December  31,  2006,  amounted  to  $91,514.  In  addition,  under a
Shareholder  Services  Plan, the Fund is authorized to make service fee payments
with respect to Class C Shares to Qualified  Recipients  for providing  personal
services and/or maintenance of shareholder accounts.  These payments are made at
the annual rate of 0.25 of 1% of the Fund's  average net assets  represented  by
Class C Shares and for the year ended December 31, 2006 amounted to $30,504. The
total of these  payments with respect to Class C Shares  amounted to $122,018 of
which the Distributor retained $28,385.



      Specific  details  about the Plans are more  fully  defined  in the Fund's
Prospectus and Statement of Additional Information.

      Under a Distribution  Agreement,  the Distributor  serves as the exclusive
distributor of the Fund's shares. Through agreements between the Distributor and
various  broker-dealer  firms ("dealers"),  the Fund's shares are sold primarily
through the facilities of these dealers having offices within Colorado, with the
bulk of sales commissions  inuring to such dealers.  For the year ended December
31, 2006,  total  commissions on sales of Class A Shares amounted to $266,785 of
which the Distributor received $49,437.

c) OTHER RELATED PARTY TRANSACTIONS:

      For the year ended December 31, 2006,  the Fund incurred  $67,122 of legal
fees  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 at that firm.

4. PURCHASES AND SALES OF SECURITIES

      During the year ended  December 31,  2006,  purchases  of  securities  and
proceeds from the sales of securities  aggregated  $17,100,030 and  $48,901,751,
respectively.

      At December  31,  2006,  the  aggregate  tax cost for all  securities  was
$208,742,557.  At December 31, 2006 the aggregate gross unrealized  appreciation
for all  securities  in which there is an excess of value over tax cost amounted
to $7,118,340 and aggregate gross unrealized  depreciation for all securities in
which  there is an excess of tax cost over value  amounted  to $85,211 for a net
unrealized appreciation of $7,033,129.

5. PORTFOLIO ORIENTATION

      Since the Fund  invests  principally  and may  invest  entirely  in double
tax-free  municipal  obligations  of issuers within  Colorado,  it is subject to
possible risks  associated with economic,  political,  or legal  developments or
industrial  or regional  matters  specifically  affecting  Colorado and whatever
effects these may have upon Colorado issuers' ability to meet their obligations.

6. EXPENSES

      The Fund has negotiated an expense offset  arrangement  with its custodian
wherein it receives credit toward the reduction of custodian fees and other Fund
expenses  whenever  there  are  uninvested  cash  balances.   The  Statement  of
Operations  reflects the total expenses before any offset,  the amount of offset
and the net expenses.

8. TRUSTEES' FEES AND EXPENSES

      At December  31, 2006 there were 7  Trustees,  one of which is  affiliated
with the Manager and is not paid any fees. The total amount of Trustees' service
and attendance fees paid during the year ended December 31, 2006 was $90,375, to
cover carrying out their  responsibilities and attendance at regularly scheduled
quarterly Board Meetings and meetings of the Independent  Trustees held prior to
each quarterly Board Meeting.  When additional or special meetings are held, the
meeting fees are paid to those Trustees in  attendance.  Trustees are reimbursed
for  their  expenses  such as  travel,  accommodations  and  meals  incurred  in
connection  with  attendance  at  Board  Meetings  and  the  Annual  Meeting  of
Shareholders.  For the  year  ended  December  31,  2006,  such  meeting-related
expenses amounted to $39,736.



9. SECURITIES TRADED ON A WHEN-ISSUED BASIS

      The  Fund  may  purchase  or  sell  securities  on  a  when-issued  basis.
When-issued transactions arise when securities are purchased or sold by the Fund
with payment and delivery  taking place in the future in order to secure what is
considered  to be an  advantageous  price  and  yield to the Fund at the time of
entering  into the  transaction.  Beginning  on the date the Fund  enters into a
when-issued  transaction,  cash or other liquid  securities are segregated in an
amount equal to or greater than the amount of the when-issued transaction. These
transactions  are  subject to market  fluctuations  and their  current  value is
determined in the same manner as for other securities.

10. INCOME TAX INFORMATION AND DISTRIBUTIONS

      The Fund declares  dividends  daily from net  investment  income and makes
payments monthly in additional shares at the net asset value per share, in cash,
or in a combination of both, at the shareholder's  option.  Net realized capital
gains, if any, are distributed annually and are taxable.

      The  Fund  intends  to  maintain,  to the  maximum  extent  possible,  the
tax-exempt  status  of  interest  payments  received  from  portfolio  municipal
securities in order to allow dividends paid to shareholders  from net investment
income to be exempt from  regular  Federal and State of Colorado  income  taxes.
However,  due  to  the  distribution  levels  maintained  by the  Fund  and  the
differences  between  financial  statement  reporting  and  Federal  income  tax
reporting  requirements,  distributions  made by the Fund may not be the same as
the Fund's net  investment  income,  and/or net realized  securities  gains.  At
December  31, 2006,  the Fund had a capital loss  carryover of $542,312 of which
$245,339  expires  in 2012 and  $296,973  expires  in 2014.  This  carryover  is
available to offset future net realized gains on securities  transactions to the
extent  provided for in the Internal  Revenue Code. To the extent that this loss
carryover is used to offset future  realized  capital gains,  it is probable the
gains so offset will not be distributed.

      The tax character of distributions:

      As of December 31, 2006, the components of distributable earnings on a tax
basis were as follows:

      Unrealized appreciation                 $7,033,129
      Accumulated net realized loss             (542,312)
                                              ----------
                                              $6,490,817
                                              ==========

      The difference between book basis and tax basis unrealized appreciation is
attributable primarily to premium/discount adjustments.

ANALYSIS OF EXPENSES (UNAUDITED)

      As a  shareholder  of the Fund,  you may  incur  two  types of costs:  (1)
transaction  costs,  including  front-end  sales charges with respect to Class A
shares or contingent  deferred  sales  charges  ("CDSC") with respect to Class C
shares; and (2) ongoing costs,  including  management fees;  distribution and/or
service  (12b-1) fees; and other Fund  expenses.  The table below is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare  these  costs with the ongoing  costs of  investing  in other  mutual
funds.

      The table below is based on an  investment  of $1,000  invested on July 1,
2006 and held for the six months ended December 31, 2006.

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".

      CONTINGENT DEFERRED SALES CHARGES ("CDSC") WITH RESPECT TO CLASS C SHARES.
      TOTAL RETURN IS NOT  ANNUALIZED,  AS IT MAY NOT BE  REPRESENTATIVE  OF THE
      TOTAL RETURN FOR THE YEAR.

(2)   EXPENSES ARE EQUAL TO THE  ANNUALIZED  EXPENSE  RATIO OF 0.77%,  1.72% AND
      0.73% FOR THE FUND'S CLASS A, C AND Y SHARES, RESPECTIVELY,  MULTIPLIED BY
      THE  AVERAGE  ACCOUNT  VALUE OVER THE  PERIOD,  MULTIPLIED  BY 184/365 (TO
      REFLECT THE ONE-HALF YEAR 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 the Fund's actual return.
The  hypothetical  account  values and  expenses may not be used to estimate the
actual ending account  balance or expenses you paid for the period.  You may use
the information provided in this table to compare the ongoing costs of investing
in the Fund and other mutual funds.  To do so,  compare this 5.00%  hypothetical
example relating to the Fund with the 5.00% hypothetical examples that appear in
the shareholder reports of other mutual funds.

      Please  note  that the  expenses  shown in the  table  below  are meant to
highlight  your ongoing  costs only and do not reflect any  transactional  costs
with respect to Class A shares.  The example  does not reflect the  deduction of
contingent  deferred  sales  charges  ("CDSC")  with  respect to Class C shares.
Therefore,  the table is useful in comparing  ongoing  costs only,  and will not
help you determine the relative total costs of owning different mutual funds. In
addition,  if these transaction costs were included,  your costs would have been
higher.

ITEM 2.  CODE OF ETHICS.

(a) As of December 31, 2006 (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
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.


ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

a) Audit Fees - The aggregate fees billed for professional services
rendered by the principal accountant for the audit of the Registrant's

b) Audit Related Fees - There were no amounts billed for audit-related

non-audit services other than those disclosed in a) thorough c) above.

e)(1)  Currently, the audit committee of the Registrant pre-approves audit
services and fees on an engagement-by-engagement basis

e)(2)  None of the services described in b) through d) above were approved
by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
Regulation S-X, all were pre-approved on an engagement-by-engagement basis.

f)  No applicable.

g) There were no non-audit services fees billed by the Registrant's accountant

ITEM 10.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

	The Board of Directors of the Registrant has adopted a Nominating
Committee Charter which provides that the Nominating Committee (the 'Committee')
may consider and evaluate nominee candidates properly submitted by shareholders
if a vacancy among the Independent Trustees of the Registrant occurs and if,
based on the Board's then current size, composition and structure, the Committee
determines that the vacancy should be filled.  The Committee will consider
candidates submitted by shareholders on the same basis as it considers and
evaluates candidates recommended by other sources.  A copy of the qualifications
and procedures that must be met or followed by shareholders to properly submit
a nominee candidate to the Committee may be obtained by submitting a request
in writing to the Secretary of the Registrant.


ITEM 11.  CONTROLS AND PROCEDURES.

(a)  Based on their evaluation of the registrant's disclosure controls and
procedures (as defined in Rule 30a-2(c) under the Investment Company Act of

deficiencies or material weaknesses that required corrective action.
