&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;The
Trust seeks monthly income that is exempt from federal and California state income taxes by investing in a pool of Closed-End Funds and
ETFs that invest primarily in California municipal bonds. However, certain distributions paid by certain Funds may be subject to federal
and California state income taxes. In addition, a portion of the income may be subject to the alternative minimum tax on individuals.
Under normal circumstances, the Trust will invest at least 80% of its assets in Closed-End Funds and ETFs that invest at least 80% of
their assets in California municipal bonds, the income from which is exempt from federal and California state income taxes. This 80% policy
is a fundamental policy and may not be changed without Unit holder approval.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: bold 11pt/12pt Times New Roman, Times, Serif; margin: 4pt 0 1pt"&gt;Portfolio Selection Process.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;The
Trust invests in Funds that invest primarily in California tax-exempt municipal bonds in order to seek monthly income that is exempt from
federal and California state income taxes. A portion of the income, however, may be derived from non-California bonds which would be taxable
to California residents. Municipal bonds are debt obligations issued by states or by political subdivisions or authorities of states.
Municipal bonds are typically designated as general obligation bonds, which are general obligations of a governmental entity that are
backed by the taxing power of such entity, or revenue bonds, which are payable from the income of a specific project or authority and
are not supported by the issuer&#x2019;s power to levy taxes. Municipal bonds are long-term fixed rate debt obligations that generally
decline in value with increases in interest rates, when an issuer&#x2019;s financial condition worsens or when the rating on a bond is
decreased.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;It
is important to note that certain Funds held by the Trust may hold securities, distributions from which would subject Unit holders to
federal income tax. Under normal circumstances, this will not account for more than 20% of the income distributed by the Trust. In addition,
certain of the Funds may hold tax-exempt securities, distributions from which may be taken into account for alternative minimum tax purposes
on individuals. Each year you will receive a tax statement which identifies what portion of your distributions, if any, are subject to
federal income taxes or the alternative minimum tax on individuals.&#160;Please refer to the &#x201c;Tax Status&#x201d; section of this
prospectus for more information.&lt;/span&gt;&lt;/p&gt;

Closed-End Funds and ETFs were selected by our research department based on a number of factors including, but not limited to, the size
and liquidity of the Closed-End Fund or ETF (requiring a minimum market capitalization of $50,000,000) and the current dividend yield
of the Closed-End Fund or ETF (prioritizing Closed-End Funds or ETFs with the highest dividend yields). The above factors are applied
separately to the Closed-End Funds and the ETFs. All other factors being equal, the Sponsor will select the Closed-End Fund or ETF with
lower expense ratios, while attempting to limit the overlap of the securities held by the Closed-End Fund or ETF.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;In
selecting the Funds for the Trust, we did not require any specific duration or maturity for the underlying municipal bonds. Moreover,
while we did not require any specific credit quality for the underlying municipal bonds, the Trust invests in Funds which primarily invest
in investment grade securities. The Funds held by the Trust may employ the use of leverage in their portfolios.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;In
connection with the Trust&#x2019;s investments in ETFs advised by First Trust Advisors L.P., an affiliate of the Trust&#x2019;s Sponsor,
First Trust Advisors L.P. will receive advisory fees from the underlying ETFs which it would not otherwise receive if the Trust invested
solely in ETFs advised by unaffiliated third-parties. This may provide an incentive for the Sponsor to select ETFs advised by First Trust
Advisors L.P. over ETFs advised by unaffiliated third-parties. &lt;/span&gt;The Sponsor may invest in an affiliated ETF even in circumstances
where an unaffiliated ETF may have lower fees or better performance over certain time periods. &lt;span style="letter-spacing: -0.05pt"&gt;However,
the Sponsor selected what it considered to be the best suited ETFs to achieve the Trust&#x2019;s investment objectives even though there
may be other ETFs, including those advised by unaffiliated third parties, that provide similar results.&lt;/span&gt;&lt;/p&gt;

assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating
leverage). Total assets for this purpose shall include assets attributable to the Fund&#x2019;s use of leverage (whether or not those assets
are reflected in the Fund&#x2019;s financial statements for purposes of generally accepted accounting principles), and derivatives will
be valued at their market value.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;The
Fund&#x2019;s investment policies provide that it will invest primarily in a portfolio of long-term, investment grade municipal obligations
issued by or on behalf of the State of California, its political subdivisions, agencies and instrumentalities and by other qualifying
issuers that pay interest which, in the opinion of bond counsel to the issuer, is exempt from federal and California income taxes (except
that the interest may be includable in taxable income for purposes of the federal alternative minimum tax) (&#x201c;California Municipal
Bonds&#x201d;). The Fund&#x2019;s investment policies provide that the Fund will seek to achieve its investment objective by seeking to
invest substantially all (a minimum of 80%) of its assets in California Municipal Bonds, except at times when, in the judgment of BlackRock
Advisors, LLC (the &#x201c;Manager&#x201d;), California Municipal Bonds of sufficient quality and quantity are unavailable for investment
at suitable prices by the Fund. For the purposes of the foregoing policy, &#x201c;assets&#x201d; are the Fund&#x2019;s net assets, plus the
amount of any borrowings for investment purposes. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus
the amount of any borrowings for investment purposes, in &#x201c;investment grade&#x201d; securities. The Fund&#x2019;s investments in derivatives
will be counted toward the foregoing 80% policies to the extent that they provide investment exposure to the securities included within
each policy or to one or more market risk factors associated with such securities. The Fund&#x2019;s investment objective and its policy
of investing at least 80% of its assets in California Municipal Bonds may not be changed without the approval of the holders of a majority
of the outstanding common shares and the outstanding preferred shares voting together as a single class, and of the holders of a majority
of the outstanding preferred shares voting as a separate class. A majority of the outstanding means (1) 67% or more of the shares present
at a meeting, if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (2) more than 50% of the
outstanding shares, whichever is less.&lt;/span&gt;&lt;/p&gt;

of its assets in California Municipal Bonds and at least 80% of its assets in California Municipal Bonds and other long-term municipal
obligations exempt from Federal income taxes, but not from California income taxes (&#x201c;Municipal Bonds&#x201d;). The Fund&#x2019;s investment
policies provide that, under normal market conditions, the Fund invests at least 80% of its assets in municipal securities with remaining
maturities of one year or more at the time of investment. The Fund ordinarily does not intend to realize significant investment income
not exempt from Federal and California income taxes. To the extent that suitable California Municipal Bonds are not available for investment
by the Fund, as determined by the Manager, the Fund may purchase Municipal Bonds&#x2026;&lt;/span&gt;&lt;/p&gt;

Fund may invest up to 20% of its managed assets in securities that are rated below investment grade, which are securities rated Ba or
below by Moody&#x2019;s, BB or below by S&amp;amp;P or Fitch or are considered by the Manager to be of comparable quality, at the time of purchase,
subject to the Fund&#x2019;s other investment policies. Below investment grade quality is regarded as predominantly speculative with respect
to the issuer&#x2019;s capacity to pay interest and repay principal. Such securities commonly are referred to as &#x201c;high yield&#x201d;
or &#x201c;junk&#x201d; bonds. &lt;/span&gt;&lt;/p&gt;

under pre-1986 law) (in general, bonds that benefit non-governmental entities) that may subject certain investors in the Fund to an alternative
minimum tax. The percentage of the Fund&#x2019;s total assets invested in private activity bonds will vary from time to time&#x2026;&lt;/span&gt;&lt;/p&gt;
