Portfolio Managers'
        COMMENTS


Portfolio managers Tom Spalding, Scott Romans and Cathryn Steeves review
economic and municipal market conditions, key investment strategies and the
annual performance of the Nuveen Select Portfolios. With 31 years of investment
experience, Tom has managed the three national Portfolios since 1999. Scott, who
joined Nuveen in 2000, has managed NXC since 2003, while Cathryn, who has been
with Nuveen since 1996, assumed portfolio management responsibility for NXN in
July 2006.


WHAT FACTORS AFFECTED THE U.S. ECONOMY AND MUNICIPAL MARKET DURING THE 12-MONTH
REPORTING PERIOD ENDED MARCH 31, 2007?

Between April 1, 2006, and March 31, 2007, we saw interest rates at the short
end of the yield curve rise modestly, while longer-term rates generally
declined. In May and June 2006, the Federal Reserve announced two additional
increases of 0.25% each in the Fed funds rate, bringing this short-term target
to 5.25%. Then, in the first pause in rate increases in more than two years, the
Fed left monetary policy unchanged during the remaining nine months of this
reporting period while it kept close tabs on inflationary pressures and the pace
of economic growth. Over the same 12-month period, the yield on the benchmark
10-year U.S. Treasury note fell 20 basis points to end March 2007 at 4.65%. In
the municipal market, the yield on the Bond Buyer 25 Revenue Bond Index, a
widely followed measure of longer-term municipal market rates, fell to 4.48% at
the end of March 2007, a decline of 66 basis points from the end of March 2006.
As shorter-term municipal bond interest rates approached the levels of
longer-term rates, the municipal bond yield curve continued to flatten, with
longer duration1 bonds generally outperforming those with shorter durations
during this period.

Although many market observers had expected to see the Fed funds rate begin to
ease in early 2007, slowing economic growth, higher energy prices, and a
slumping housing market kept the Fed on the sidelines. After posting an
annualized gain of 5.6% in the first quarter of 2006, the U.S. gross domestic
product, a closely watched measure, expanded 2.6% in the second quarter, 2.0% in
the third quarter, and 2.5% in the fourth quarter (all GDP numbers annualized).
In the first quarter of 2007, the rate of GDP growth slowed even further to an
annualized 1.3%, the weakest rate in four years.


1    Duration is a measure of a bond's price sensitivity as interest rates
     change, with longer duration bonds displaying more sensitivity to these
     changes than bonds with shorter durations.


                                       4



Over the 12 months ended March 2007, municipal bond issuance nationwide totaled
$417.8 billion, up 11% from the previous 12 months. This total reflected record
supply during the first three months of 2007, when $104 billion in new
securities came to market, an increase of 49% from the same period in 2006. A
major factor in the first quarter 2007 volume was an 88% increase in advance
refundings2, driven by attractive borrowing rates for issuers. Strong demand for
municipal bonds was more than adequate to absorb the surge in issuance, as
retail investors, institutional investors such as hedge funds and arbitragers,
and overseas investors all participated in the market.


HOW WERE ECONOMIC AND MARKET CONDITIONS IN CALIFORNIA AND NEW YORK DURING THIS
PERIOD?

During this reporting period, California's economy remained diverse, with
international trade, technology, tourism, finance, defense, and construction
serving as the key drivers. The state's economy continued to expand at a
moderate pace, slowed somewhat by a softening housing market, but buoyed by
gains in manufacturing. As of March 2007, California's unemployment rate was
4.8%, still above the national rate of 4.4%. In May 2006, both Moody's and
Standard & Poor's upgraded their ratings on California's general obligation (GO)
debt to A1 from A2 and to A+ from A, respectively. Fitch also upgraded its
rating to A1 from A2 in June 2006. In announcing the upgrades, the rating
agencies cited strong economic and tax revenue trends.

For the 12 months ended March 31, 2007, municipal issuance in California totaled
$59.9 billion, a increase of 10% from the previous 12 months. During the first
three months of 2007, supply of new issuance in the state hit $20.5 billion, up
122% from January-March 2006, due largely to two major deals: $4.5 billion in
Golden State Tobacco Securitization bonds and $4.1 billion in a California
general obligation (GO) bonds refunding issue. California continued to rank as
the largest state issuer in the nation for both time periods.


2    Advance refundings, also known as pre-refundings or refinancings, occur
     when an issuer sells new bonds and uses the proceeds to fund principal and
     interest payments of older existing bonds. This process often results in
     lower borrowing costs for bond issuers.


                                       5



New York's economy continued to be led by financial services, health care,
education, and professional and business services. Although more diversified
than it was a decade ago, the state's economy remained highly dependent on the
financial services sector, making it susceptible to economic cycles. Most of the
state's recent economic growth has been centered around New York City and its
suburbs, as the upstate area continued to experience losses in the manufacturing
sector. In March 2007, unemployment in New York stood at 4.0%, down from 4.7% in
March 2006, the lowest point in almost 19 years and well below the national
average at 4.4%. Following 20 years of late budgets, the enactment of the fiscal
2008 budget marked the third year in a row that New York met the legally
required April 1, 2007 deadline. As of March 2007, New York State general
obligation bonds were rated Aa3 by Moody's, AA by S&P, and AA- by Fitch.

During the reporting period ended March 31, 2007, municipal issuance in New York
totaled $33.9 billion, a decrease of 16% from the previous 12 months. The first
three months of 2007, however, saw an increase in state supply, with $7.4
billion in new issuance, up 13% from the first quarter of 2006. For both
periods, New York ranked third in the nation, following California and Texas, in
terms of municipal issuance.


WHAT KEY STRATEGIES WERE USED TO MANAGE THE NUVEEN SELECT PORTFOLIOS DURING THIS
REPORTING PERIOD?

In the municipal bond interest rate environment of the past 12 months, where the
flattening yield curve remained a dominant market factor, we continued to
emphasize a disciplined approach to duration management and yield curve
positioning. As part of this approach, our purchases for the Portfolios focused
mainly on attractively priced bonds maturing in 20 years and longer in the
national Portfolios, 20 to 25 years in NXC, and at least 25 years in NXN.
Overall, we believe that the bonds we purchased during this period offered
strong performance potential, superior value, and reward opportunities
commensurate with their risk levels.


                                       6



Our duration management strategies during this period also included adding
inverse floating rate trusts3, a type of derivative financial instrument, to
NXQ, NXR, NXC, and NXN roughly mid-way through the reporting period. The inverse
floaters had the dual benefit of increasing the Portfolios' distributable income
and bringing their durations closer to our preferred strategic target.

To help us maintain NXC's and NXN's durations within that strategic range and to
fund new purchases, we also selectively sold holdings with shorter durations
and, in NXC, insured credits where we believed the income component was not as
robust. In NXC, we also found opportunities when rates were higher during the
first four months of the period (April-July 2006) to sell some of our holdings
that were purchased when yields were lower and replace them with similar, newer
credits that yielded incrementally more. These transactions were carried out
only when new purchases offered strong and compelling income (e.g., lower-rated
hospital and tobacco bonds). This process allowed us to maintain NXC's current
characteristics while strengthening its income stream. In the national
Portfolios, new purchases were generally funded with proceeds from called bonds
rather than proceeds realized through active selling.

During this period, a number of large municipal deals were brought to market,
which provided us with more bonds from which to choose in implementing the
strategies we had planned for these Portfolios. In the national Portfolios,
these strategies included keeping them fully invested, purchasing bonds with
good cashflows to support their dividends, and adding zero coupon bonds to
maintain or lengthen durations. The majority of our purchases during this period
were essential services revenue bonds issued in Texas, Washington, Colorado and
South Carolina, which helped to keep the Portfolios well-diversified
geographically. One notable exception to the overall high quality of our
purchases was the recent addition of newly issued California tobacco bonds
(Golden State Tobacco Securitization) to NXQ and NXR.


3    A financial instrument designed to pay long-term tax-exempt interest at a
     rate that varies inversely with a short-term tax-exempt interest rate
     index. For the Nuveen funds, that index is typically The Securities
     Industry and Financial Markets (SIFM) Municipal Swap Index (previously
     referred to as the Bond Market Association Index or BMA.) Inverse floaters,
     including those inverse floating rate securities the Funds invested in
     during the 12 month period, are further defined within the Notes to
     Financial Statements and Glossary of Terms Used in This Report sections of
     this shareholder report.


                                       7



Despite the continued tightening of credit spreads over this period, the
California and New York municipal markets both offered some attractively
structured lower-rated credit opportunities in the primary as well as the
secondary markets. In NXC, we purchased the new bonds issued as part of the
Golden State Tobacco Securitization refunding as well as some lower-rated health
care credits, including A+ rated bonds issued for the Kaiser Permanente System.
We also continued to diversify the Portfolio by buying zero coupon bonds and
insured single-family housing bonds. In NXN, we continued to find value in
lower-rated health care credits.

4    The Lehman Brothers Municipal Bond Index is an unleveraged, unmanaged
     national index containing a broad range of investment-grade municipal
     bonds. The Lehman Brothers Tax-Exempt Bond Indexes for California and New
     York are also unleveraged and unmanaged and comprise a broad range of
     municipal bonds issued in California and New York, respectively. Results
     for the Lehman Brothers indexes do not reflect any expenses.

5    Each of the Lipper Municipal Debt Funds averages shown in this report are
     calculated using the returns of all closed-end funds in their respective
     categories for each period as follows: Lipper General and Insured
     Unleveraged category, 1 year, 9; 5 years, 8; and 10 years, 8; Lipper
     California category, 1 year, 25; 5 years, 21; and 10 years, 13; and Lipper
     New York category, 1 year, 18; 5 years, 14; and 10 years, 7. Portfolio and
     Lipper returns assume reinvestment of dividends.

For the 12 months ended March 31, 2007, the total returns on net asset value
(NAV) for NXQ and NXR outperformed the return on the Lehman Brothers Municipal
Bond Index, while NXP performed inline with the Index. NXC and NXN exceeded the
returns on the Lehman Brothers Tax-Exempt Bond Indexes for California and New
York, respectively.

Factors that influenced the Portfolios' returns during this period included
duration and yield curve positioning, exposure to lower-rated credits sector and
security selection, and advance refunding activity.

As previously mentioned, shorter-term rates rose while longer-term rates
declined over the course of this period, and as a result, bonds with longer
durations generally outperformed shorter duration bonds. However, the durations
of the national PortfoliosNXQ, and NXR--continued to be a little short of their
target range and this factor was a slight negative for performance. In NXC and
NXN, duration and yield curve positioning were positive contributors to
performance. Although NXN continued to be underexposed to bonds in the longest
part of the yield curve, this was offset by heavy weightings in the intermediate
part of the curve and only a small position in shorter bonds.

With bonds rated BBB or lower and non-rated bonds generally outperforming other
credit quality sectors during this period, all of the Portfolios benefited from
their exposure to lower-quality credits. The performance of these credit sectors
was largely the result of investor demand for the higher yields typically
associated with lower-rated bonds, which drove up their value. Overall, NXC, had
relatively heavier exposure to lower-rated credits than the other Portfolios,
which meant that this Portfolio benefited to a greater extent from the
outperformance of these credits.


                                       10



Among the lower-rated holdings making contributions to the Portfolios' returns
were health care (including hospitals) credits and industrial development and
resource recovery bonds, which ranked among the top performing revenue sectors
in the national Lehman Brothers Municipal Bond Index for this period.
Lower-rated bonds backed by the 1998 master tobacco settlement agreement also
performed well during this period. As of March 31, 2007, the national Portfolios
held between 2% and 4% of their portfolios in tobacco bonds, while NXC and NXN
had allocated approximately 5% and 2%, respectively, to these credits.

In addition, NXP, NXQ, NXR and NXC all had good exposure to zero coupon bonds,
which were among the best performing credits during this period due to their
very long durations. In NXC, for example, zero coupon bonds represented the top
six performing holdings for this 12-month period.

We also continued to see positive contributions from advance refunding activity,
which benefited each of these Portfolios through price appreciation and enhanced
credit quality. Identifying purchase candidates that have the potential to
appreciate in value through advance refundings or credit improvement is one way
our credit research capabilities help to add value to these Portfolios. Among
the national Portfolios' holdings that were pre-refunded during this period were
BBB rated Golden State Tobacco Securitization credits, while NXC's
advance-refunded credits included A2 rated bonds issued for the University of
the Pacific and uninsured A+ rated California state general obligation (GO)
bonds.

At the same time, the Portfolios' holdings of older, previously pre-refunded
bonds tended to underperform the general municipal market during this period,
due primarily to their shorter effective maturities. Among the three national
Portfolios, NXP had the heaviest allocation of pre-refunded bonds going into
this period.

Dividend and Share Price
       INFORMATION


During the 12-month reporting period ended March 31, 2007, the dividends of all
five of the Select Portfolios remained stable.

Due to normal portfolio activity, common shareholders of the following
Portfolios received capital gains distributions at the end of December 2006, as
follows:

             LONG-TERM CAPITAL GAINS
                         (PER SHARE)
--------------------------------------------------------------------------------
NXC                          $0.0224
--------------------------------------------------------------------------------
NXN                          $0.0364
--------------------------------------------------------------------------------

All of these Portfolios seek to pay stable dividends at rates that reflect each
Portfolio's past results and projected future performance. During certain
periods, each Portfolio may pay dividends at a rate that may be more or less
than the amount of net investment income actually earned by the Portfolio during
the period. If a Portfolio has cumulatively earned more than it has paid in
dividends, it holds the excess in reserve as undistributed net investment income
(UNII) as part of the Portfolio's NAV. Conversely, if a Portfolio has
cumulatively paid dividends in excess of its earnings, the excess constitutes
negative UNII that is likewise reflected in the Portfolio's NAV. Each Portfolio
will, over time, pay all of its net investment income as dividends to
shareholders. As of March 31, 2007, NXP had positive UNII balances for both
financial statement and tax purposes. NXQ, NXR, NXC and NXN had positive UNII
balances for tax purposes and negative UNII balances for financial statement
purposes.

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of Nuveen Select Tax-Free Income Portfolio,
Nuveen Select Tax-Free Income Portfolio 2, Nuveen Select Tax-Free Income
Portfolio 3, Nuveen California Select Tax-Free Income Portfolio, and Nuveen New
York Select Tax-Free Income Portfolio, as of March 31, 2007, and the related
statements of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

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. We were
not engaged to perform an audit of the Funds' 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 Funds' 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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of March 31, 2006, by correspondence with the custodian and
brokers, or by other appropriate auditing procedures where replies from brokers
were not received. 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 positions of
Nuveen Select Tax-Free Income Portfolio, Nuveen Select Tax-Free Income Portfolio
2, Nuveen Select Tax-Free Income Portfolio 3, Nuveen California Select Tax-Free
Income Portfolio, and Nuveen New York Select Tax-Free Income Portfolio at March
31, 2007, the results of their operations for the year then ended, changes in
their net assets for each of the two years in the period then ended, and their
financial highlights for each of the five years in the period then ended in
conformity with U.S. generally accepted accounting principles.

       FINANCIAL STATEMENTS


1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

The funds (the "Funds") covered in this report and their corresponding New York
Stock Exchange symbols are Nuveen Select Tax-Free Income Portfolio (NXP), Nuveen
Select Tax-Free Income Portfolio 2 (NXQ), Nuveen Select Tax-Free Income
Portfolio 3 (NXR), Nuveen California Select Tax-Free Income Portfolio (NXC) and
Nuveen New York Select Tax-Free Income Portfolio (NXN). The Funds are registered
under the Investment Company Act of 1940, as amended, as closed-end, diversified
management investment companies.

Each Fund seeks to provide stable dividends consistent with the preservation of
capital, exempt from regular federal and designated state income taxes, where
applicable, by investing primarily in a diversified portfolio of municipal
obligations.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with U.S.
generally accepted accounting principles.

Investment Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When market price
quotes are not readily available (which is usually the case for municipal
securities), the pricing service may establish fair value based on yields or
prices of municipal bonds of comparable quality, type of issue, coupon, maturity
and rating, indications of value from securities dealers, evaluations of
anticipated cash flows or collateral and general market conditions. If the
pricing service is unable to supply a price for a municipal bond, each Fund may
use a market price or fair market value quote provided by a major broker/dealer
in such investments. If it is determined that the market price or fair market
value for an investment is unavailable or inappropriate, the Board of Trustees
of the Funds, or its designee, may establish a fair value for the investment.
Temporary investments in securities that have variable rate and demand features
qualifying them as short-term investments are valued at amortized cost, which
approximates market value.

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and
losses from transactions are determined on the specific identification method.
Investments purchased on a when-issued/delayed delivery basis may have extended
settlement periods. Any investments so purchased are subject to market
fluctuation during this period. The Funds have instructed the custodian to
segregate assets with a current value at least equal to the amount of the
when-issued/delayed delivery purchase commitments. At March 31, 2007, there were
no such outstanding purchase commitments in any of the Funds.

Investment Income

Interest income, which includes the amortization of premiums and accretion of
discounts for financial reporting purposes, is recorded on an accrual basis.
Investment income also includes paydown gains and losses, if any.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute substantially all net investment income and net capital
gains to shareholders and to otherwise comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies. Therefore, no federal income tax provision is required. Furthermore,
each Fund intends to satisfy conditions which will enable interest from
municipal securities, which is exempt from regular federal and applicable state
income taxes, if any, to retain such tax-exempt status when distributed to
shareholders of the Funds. Net realized capital gains and ordinary income
distributions paid by the Funds are subject to federal taxation.


                                       52



Dividends and Distributions to Shareholders

Dividends from tax-exempt net investment income are declared monthly. Net
realized capital gains and/or market discount from investment transactions, if
any, are distributed to shareholders not less frequently than annually.
Furthermore, capital gains are distributed only to the extent they exceed
available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount, if any, are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from U.S. generally accepted
accounting principles.

Derivative Financial Instruments

The Funds are authorized to invest in certain derivative financial instruments
including futures, forward, swap and option contracts, and other financial
instruments with similar characteristics. Although the Funds are authorized to
invest in such instruments, and may do so in the future, they did not invest in
any such instruments during the fiscal year ended March 31, 2007.

Inverse Floating Rate Securities

Each Fund may invest in inverse floating rate securities. An inverse floating
rate security is created by depositing a municipal bond, typically with a fixed
interest rate, into a special purpose trust created by a broker-dealer. In turn,
this trust (a) issues floating rate certificates, in face amounts equal to some
fraction of the deposited bond's par amount or market value, that typically pay
short-term tax-exempt interest rates to third parties, and (b) issues to a
long-term investor (such as one of the Funds) an inverse floating rate
certificate (sometimes referred to as an "inverse floater") that represents all
remaining or residual interest in the trust. The income received by the inverse
floater holder varies inversely with the short-term rate paid to the floating
rate certificates' holders, and in most circumstances the inverse floater holder
bears substantially all of the underlying bond's downside investment risk and
also benefits disproportionately from any potential appreciation of the
underlying bond's value. The price of an inverse floating rate security will be
more volatile than that of the underlying bond because the interest rate is
dependent on not only the fixed coupon rate of the underlying bond but also on
the short-term interest paid on the floating rate certificates, and because the
inverse floating rate security essentially bears the risk of loss of the greater
face value of the underlying bond.

A Fund may purchase an inverse floating rate security in a secondary market
transaction without first owning the underlying bond (referred to as an
"externally-deposited inverse floater"), or instead by first selling a
fixed-rate bond to a broker-dealer for deposit into the special purpose trust
and receiving in turn the residual interest in the trust (referred to as a
"self-deposited inverse floater"). An investment in an externally-deposited
inverse floater is identified in the Portfolio of Investments as an "Inverse
floating rate investment". An investment in a self-deposited inverse floater is
accounted for as a financing transaction in accordance with Statement of
Financial Accounting Standards (SFAS) No. 140 "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities". In such
instances, a fixed-rate bond deposited into a special purpose trust is
identified in the Portfolio of Investments as an "Underlying bond of an inverse
floating rate trust", with the Fund accounting for the short-term floating rate
certificates issued by the trust as "Floating rate obligations" on the Statement
of Assets and Liabilities. In addition, the Fund reflects in Investment Income
the entire earnings of the underlying bond and accounts for the related interest
paid to the holders of the short-term floating rate certificates as "Floating
rate obligations interest expense and fees" in the Statement of Operations.

During the fiscal year ended March 31, 2007, Select Tax-Free 2 (NXQ), Select
Tax-Free 3 (NXR), California Select Tax-Free (NXC) and New York Select Tax-Free
(NXN) invested in externally deposited inverse floaters and/or self-deposited
inverse floaters. Select Tax-Free (NXP) did not invest in any such instruments
during the fiscal year ended March 31, 2007.

The average floating rate obligations outstanding and average annual interest
rate and fees related to self-deposited inverse floaters during the fiscal year
ended March 31, 2007, were as follows:


                                                                                              CALIFORNIA   NEW YORK

Notes to
    FINANCIAL STATEMENTS (continued)


Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian
fees and expenses are reduced by credits earned on each Fund's cash on deposit
with the bank. Such deposit arrangements are an alternative to overnight
investments.

Indemnifications

Under the Funds' organizational documents, their Officers and Trustees are
indemnified against certain liabilities arising out of the performance of their
duties to the Funds. In addition, in the normal course of business, the Funds
enter into contracts that provide general indemnifications to other parties. The
Funds' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Funds that have not yet
occurred. However, the Funds have not had prior claims or losses pursuant to
these contracts and expect the risk of loss to be remote.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities 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 may differ from those estimates.

4. INCOME TAX INFORMATION

The following information is presented on an income tax basis. Differences
between amounts for financial statement and federal income tax purposes are
primarily due to the treatment of paydown gains and losses, timing differences
in recognizing taxable market discount, timing differences in recognizing
certain gains and losses on investment transactions and the treatment of
investments in inverse floating rate transactions subject to SFAS No. 140. To
the extent that differences arise that are permanent in nature, such amounts are
reclassified within the capital accounts on the Statement of Assets and
Liabilities presented in the annual report, based on their federal tax basis
treatment; temporary differences do not require reclassification. Temporary and
permanent differences do not impact the net asset values of the Funds.

At March 31, 2007, the cost of investments was as follows:


                                                                                      CALIFORNIA       NEW YORK

5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Each Fund's management fee is separated into two components - a complex-level
component, based on the aggregate amount of all fund assets managed by Nuveen
Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen
Investments, Inc. ("Nuveen"), and a specific fund-level component, based only on
the amount of assets within each individual fund. This pricing structure enables
Nuveen fund shareholders to benefit from growth in the assets within each
individual fund as well as from growth in the amount of complex-wide assets
managed by the Adviser.

The annual fund-level fee, payable monthly, for each Fund is based upon the
average daily net assets of each Fund as follows:


                                                               SELECT TAX-FREE 2 (NXQ)

For the first $125 million                   .0500%                             .1000%
For the next $125 million                    .0375                              .0875
For the next $250 million                    .0250                              .0750

======================================================================================


The annual complex-level fee, payable monthly, which is additive to the
fund-level fee, for all Nuveen sponsored funds in the U.S., is based on the
aggregate amount of total fund assets managed as stated in the table below. As
of March 31, 2007, the complex-level fee rate was .1834%.

COMPLEX-LEVEL ASSETS(1)                                   COMPLEX-LEVEL FEE RATE
--------------------------------------------------------------------------------

For the next $1 billion                                                   .1800
For the next $1 billion                                                   .1600
For the next $3 billion                                                   .1425
For the next $3 billion                                                   .1325
For the next $3 billion                                                   .1250
For the next $5 billion                                                   .1200
For the next $5 billion                                                   .1175
For the next $15 billion                                                  .1150
For Managed Assets over $91 billion(2)                                    .1400
================================================================================
(1)  The complex-level fee component of the management fee for the funds is
     calculated based upon the aggregate Managed Assets ("Managed Assets" means
     the average daily net assets of each fund including assets attributable to
     preferred stock issued by or borrowings by the Nuveen funds) of
     Nuveen-sponsored funds in the U.S.

(2)  With respect to the complex-wide Managed Assets over $91 billion, the fee
     rate or rates that will apply to such assets will be determined at a later
     date. In the unlikely event that complex-wide Managed Assets reach $91
     billion prior to a determination of the complex-level fee rate or rates to
     be applied to Managed Assets in excess of $91 billion, the complex-level
     fee rate for such complex-wide Managed Assets shall be .1400% until such
     time as a different rate or rates is determined.

The management fee compensates the Adviser for overall investment advisory and
administrative services and general office facilities. The Funds pay no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its Officers, all of whom receive remuneration for their services
to the Funds from the Adviser or its affiliates. The Board of Trustees has
adopted a deferred compensation plan for independent Trustees that enables
Trustees to elect to defer receipt of all or a portion of the annual
compensation they are entitled to receive from certain Nuveen advised funds.
Under the plan, deferred amounts are treated as though equal dollar amounts had
been invested in shares of select Nuveen advised funds.

6. NEW ACCOUNTING PRONOUNCEMENTS

Financial Accounting Standards Board Interpretation No. 48

On July 13, 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 Funds' 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 for fiscal years beginning after December 15, 2006, and is to be
applied to all open tax years as of the effective date. Recent SEC guidance
allows funds to delay implementing FIN 48 into NAV calculations until the fund's
last NAV calculation in the first required financial statement reporting period.
As a result, the Funds must begin to incorporate FIN 48 into their NAV
calculations by September 28, 2007. At this time, management is continuing to
evaluate the implications of FIN 48 and does not expect the adoption of FIN 48
will have a significant impact on the net assets or results of operations of the
Funds.

Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 157

In September 2006, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 157, "Fair Value
Measurements." This standard establishes a single authoritative definition of
fair value, sets out a framework for measuring fair value and requires
additional disclosures about fair value measurements. SFAS No. 157 applies to
fair value measurements already required or permitted by existing standards.
SFAS No. 157 is effective for financial statements issued for fiscal years
beginning after November 15, 2007, and interim periods within those fiscal
years. The changes to current generally accepted accounting principles from the
application of this standard relate to the definition of fair value, the methods
used to measure fair value, and the expanded disclosures about fair value
measurements. As of March 31, 2007, the Funds do not believe the adoption of
SFAS No. 157 will impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements included within the Statement of
Operations for the period.

     price per share and the effect of reinvested dividend income and reinvested
     capital gains distributions, if any, at the average price paid per share at
     the time of reinvestment. Total Return on Net Asset Value is the

Reinvest Automatically
       EASILY AND CONVENIENTLY

Sidebar text: NUVEEN MAKES REINVESTING EASY. A PHONE CALL IS ALL IT TAKES TO SET
UP YOUR REINVESTMENT ACCOUNT.



NUVEEN CLOSED-END FUNDS
DIVIDEND REINVESTMENT PLAN

Your Nuveen Closed-End Fund allows you to conveniently reinvest dividends and/or
capital gains distributions in additional Fund shares.

By choosing to reinvest, you'll be able to invest money regularly and
automatically, and watch your investment grow through the power of tax-free
compounding. Just like dividends or distributions in cash, there may be times
when income or capital gains taxes may be payable on dividends or distributions
that are reinvested.

It is important to note that an automatic reinvestment plan does not ensure a
profit, nor does it protect you against loss in a declining market.

EASY AND CONVENIENT

To make recordkeeping easy and convenient, each month you'll receive a statement
showing your total dividends and distributions, the date of investment, the
shares acquired and the price per share, and the total number of shares you own.

HOW SHARES ARE PURCHASED

The shares you acquire by reinvesting will either be purchased on the open
market or newly issued by the Fund. If the shares are trading at or above net
asset value at the time of valuation, the Fund will issue new shares at the
greater of the net asset value or 95% of the then-current market price. If the
shares are trading at less than net asset value, shares for your account will be
purchased on the open market. If the Plan Agent begins purchasing Fund shares on
the open market while shares are trading below net asset value, but the Fund's
shares subsequently trade at or above their net asset value before the Plan
Agent is able to complete its purchases, the Plan Agent may cease open-market
purchases and may invest the uninvested portion of the distribution in
newly-issued Fund shares at a price equal to the greater of the shares' net
asset value or 95% of the shares' market value on the last business day
immediately prior to the purchase date. Dividends and distributions received to
purchase shares in the open market will normally be invested shortly after the
dividend payment date. No interest will be paid on dividends and distributions
awaiting reinvestment. Because the market price of the shares may increase
before purchases are completed, the average purchase price per share may exceed
the market price at the time of valuation, resulting in the acquisition of fewer
shares than if the dividend or distribution had been paid in shares issued by
the Fund. A pro rata portion of any applicable brokerage commissions on open
market purchases will be paid by Plan participants. These commissions usually
will be lower than those charged on individual transactions.


                                       72


FLEXIBLE

You may change your distribution option or withdraw from the Plan at any time,
should your needs or situation change. Should you withdraw, you can receive a
certificate for all whole shares credited to your reinvestment account and cash
payment for fractional shares, or cash payment for all reinvestment account
shares, less brokerage commissions and a $2.50 service fee.

You can reinvest whether your shares are registered in your name, or in the name
of a brokerage firm, bank, or other nominee. Ask your investment advisor if his
or her firm will participate on your behalf. Participants whose shares are
registered in the name of one firm may not be able to transfer the shares to
another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although
the Fund reserves the right to amend the Plan to include a service charge
payable by the participants, there is no direct service charge to participants
in the Plan at this time.

Glossary of
       TERMS USED IN THIS REPORT



AVERAGE ANNUAL TOTAL RETURN: This is a commonly used method to express an
investment's performance over a particular, usually multi-year time period. It
expresses the return that would have been necessary each year to equal the
investment's actual cumulative performance (including change in NAV or market
price and reinvested dividends and capital gains distributions, if any) over the
time period being considered.

AVERAGE EFFECTIVE MATURITY: The average of the number of years to maturity of
the bonds in a Fund's portfolio, computed by weighting each bond's time to
maturity (the date the security comes due) by the market value of the security.
This figure does not account for the likelihood of prepayments or the exercise
of call provisions unless an escrow account has been established to redeem the
bond before maturity. The market value weighting for an investment in an inverse
floating rate security is the value of the portfolio's residual interest in the
inverse floating rate trust, and does not include the value of the floating rate
securities issued by the trust.

INVERSE FLOATERS: Inverse floating rate securities are created by depositing a
municipal bond, typically with a fixed interest rate, into a special purpose
trust created by a broker-dealer. This trust, in turn, (a) issues floating rate
certificates typically paying short-term tax-exempt interest rates to third
parties in amounts equal to some fraction of the deposited bond's par amount or
market value, and (b) issues an inverse floating rate certificate (sometimes
referred to as an "inverse floater") to an investor (such as a Fund) interested
in gaining investment exposure to a long-term municipal bond. The income
received by the holder of the inverse floater varies inversely with the
short-term rate paid to the floating rate certificates' holders, and in most
circumstances the holder of the inverse floater bears substantially all of the
underlying bond's downside investment risk. The holder of the inverse floater
typically also benefits disproportionately from any potential appreciation of
the underlying bond's value. Hence, an inverse floater essentially represents an
investment in the underlying bond on a leveraged basis.

LEVERAGE-ADJUSTED DURATION: Duration is a measure of the expected period over
which a bond's principal and interest will be paid, and consequently is a
measure of the sensitivity of a bond's or bond Fund's value to changes when
market interest rates change. Generally, the longer a bond's or Fund's duration,
the more the price of the bond or Fund will change as interest rates change.
Leverage-adjusted duration takes into account the leveraging process for a Fund
and therefore is longer than the duration of the Fund's portfolio of bonds.

MARKET YIELD (ALSO KNOWN AS DIVIDEND YIELD OR CURRENT YIELD): An investment's
current annualized dividend divided by its current market price.

NET ASSET VALUE (NAV): A Fund's common share NAV per share is calculated by
subtracting the liabilities of the Fund (including any MuniPreferred shares
issued in order to leverage the Fund) from its total assets and then dividing
the remainder by the number of shares outstanding. Fund NAVs are calculated at
the end of each business day.

TAXABLE-EQUIVALENT YIELD: The yield necessary from a fully taxable investment to
equal, on an after-tax basis, the yield of a municipal bond investment.


                                       74

Each Fund's (i) quarterly portfolio of investments, (ii) information regarding

Nuveen Investments toll-free at (800) 257-8787 or on Nuveen's website at

CEO CERTIFICATION DISCLOSURE

For Funds listed on the New York Stock Exchange, each Fund's Chief Executive
Officer has submitted to the Exchange the annual CEO certification as required
by Section 303A.12(a) of the NYSE Listed Company Manual.

Each Fund has filed with the Securities and Exchange Commission the
certification of its Chief Executive Officer and Chief Financial Officer
required by Section 302 of the Sarbanes-Oxley Act.

INVESTMENT POLICY CHANGE

In February 2007, the Board of Trustees for Nuveen California Select Tax-Free
(NXC) and Nuveen New York Select Tax-Free (NXN) voted to remove investment
policy restrictions that limited the territorial bond holdings of these Funds to
a maximum of 10 percent of net assets. This change will give the Funds'
portfolio managers greater flexibility to achieve its investment objectives.

ITEM 2. CODE OF ETHICS.

As of the end of the period covered by this report, the registrant has adopted a
code of ethics that applies to the registrant's principal executive officer,
principal financial officer, principal accounting officer or controller, or
persons performing similar functions. There were no amendments to or waivers
from the Code during the period covered by this report. The registrant has
posted the code of ethics on its website at www.nuveen.com/etf. (To view the
code, click on the Investor Resources drop down menu box, click on Fund
Governance and then click on Code of Conduct.)

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Directors or Trustees determined that the registrant
has at least one "audit committee financial expert" (as defined in Item 3 of
Form N-CSR) serving on its Audit Committee. The registrant's audit committee
financial expert is Jack B. Evans, Chairman of the Audit Committee, who is
"independent" for purposes of Item 3 of Form N-CSR.

Mr. Evans was formerly President and Chief Operating Officer of SCI Financial
Group, Inc., a full service registered broker-dealer and registered investment
adviser ("SCI"). As part of his role as President and Chief Operating Officer,
Mr. Evans actively supervised the Chief Financial Officer (the "CFO") and
actively supervised the CFO's preparation of financial statements and other
filings with various regulatory authorities. In such capacity, Mr. Evans was
actively involved in the preparation of SCI's financial statements and the
resolution of issues raised in connection therewith. Mr. Evans has also served
on the audit committee of various reporting companies. At such companies, Mr.
Evans was involved in the oversight of audits, audit plans, and the preparation
of financial statements. Mr. Evans also formerly chaired the audit committee of
the Federal Reserve Bank of Chicago.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

                     Nuveen Select Tax-Free Income Portfolio

The following tables show the amount of fees that Ernst & Young LLP, the Fund's
auditor, billed to the Fund during the Fund's last two full fiscal years. For
engagements with Ernst & Young LLP the Audit Committee approved in advance all
audit services and non-audit services that Ernst & Young LLP provided to the
Fund, except for those non-audit services that were subject to the pre-approval
exception under Rule 2-01 of Regulation S-X (the "pre-approval exception"). The
pre-approval exception for services provided directly to the Fund waives the
pre-approval requirement for services other than audit, review or attest
services if: (A) the aggregate amount of all such services provided constitutes
no more than 5% of the total amount of revenues paid by the Fund to its
accountant during the fiscal year in which the services are provided; (B) the
Fund did not recognize the services as non-audit services at the time of the
engagement; and (C) the services are promptly brought to the Audit Committee's
attention, and the Committee (or its delegate) approves the services before the
audit is completed.

The Audit Committee has delegated certain pre-approval responsibilities to its
Chairman (or, in his absence, any other member of the Audit Committee).

(1)  "Audit Fees" are the aggregate fees billed for professional services for
     the audit of the Fund's annual financial statements and services provided
     in connection with statutory and regulatory filings or engagements.

(2)  "Audit Related Fees" are the aggregate fees billed for assurance and
     related services reasonably related to the performance of the audit or
     review of financial statements and are not reported under "Audit Fees".

(3)  "Tax Fees" are the aggregate fees billed for professional services for tax
     advice, tax compliance, and tax planning.

(4)  "All Other Fees" are the aggregate fees billed for products and services
     other than "Audit Fees", "Audit Related Fees", and "Tax Fees".

                 SERVICES THAT THE FUND'S AUDITOR BILLED TO THE
                  ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

The following tables show the amount of fees billed by Ernst & Young LLP to
Nuveen Asset Management ("NAM" or the "Adviser"), and any entity controlling,
controlled by or under common control with NAM ("Control Affiliate") that
provides ongoing services to the Fund ("Affiliated Fund Service Provider"), for
engagements directly related to the Fund's operations and financial reporting,
during the Fund's last two full fiscal years.

The tables also show the percentage of fees subject to the pre-approval
exception. The pre-approval exception for services provided to the Adviser and
any Affiliated Fund Service Provider (other than audit, review or attest
services) waives the pre-approval requirement if: (A) the aggregate amount of
all such services provided constitutes no more than 5% of the total amount of
revenues paid to Ernst & Young LLP by the Fund, the Adviser and Affiliated Fund
Service Providers during the fiscal year in which the services are provided that
would have to be pre-approved by the Audit Committee; (B) the Fund did not
recognize the services as non-audit services at the time of the engagement; and
(C) the services are promptly brought to the Audit Committee's attention, and
the Committee (or its delegate) approves the services before the Fund's audit is
completed.

(1)  The amounts reported for the Fund under the column heading "Tax Fees"
     represents amounts billed to the Adviser exclusively for the preparation
     for the Fund's tax return, the cost of which is borne by the Adviser. In
     the aggregate, for all Nuveen funds for which Ernst & Young LLP serves as
     independent registered public accounting firm, these fees amounted to
     $161,400 in 2006. Beginning with fund fiscal years ending August 31, 2006,
     Ernst & Young LLP will no longer prepare the fund tax returns.

                               NON-AUDIT SERVICES

The following table shows the amount of fees that Ernst & Young LLP billed
during the Fund's last two full fiscal years for non-audit services. The Audit
Committee is required to pre-approve non-audit services that Ernst & Young LLP
provides to the Adviser and any Affiliated Fund Services Provider, if the
engagement related directly to the Fund's operations and financial reporting
(except for those subject to the de minimis exception described above). The
Audit Committee requested and received information from Ernst & Young LLP about
any non-audit services that Ernst & Young LLP rendered during the Fund's last
fiscal year to the Adviser and any Affiliated Fund Service Provider. The
Committee considered this information in evaluating Ernst & Young LLP's
independence.

"Non-Audit Fees billed to Adviser" for both fiscal year ends represent "Tax
Fees" billed to Adviser in their respective amounts from the previous table.

Audit Committee Pre-Approval Policies and Procedures. Generally, the Audit
Committee must approve (i) all non-audit services to be performed for the Fund
by the Fund's independent accountants and (ii) all audit and non-audit services
to be performed by the Fund's independent accountants for the Affiliated Fund
Service Providers with respect to operations and financial reporting of the
Fund. Regarding tax and research projects conducted by the independent
accountants for the Fund and Affiliated Fund Service Providers (with respect to
operations and financial reports of the Fund) such engagements will be (i)
pre-approved by the Audit Committee if they are expected to be for amounts
greater than $10,000; (ii) reported to the Audit Committee chairman for his
verbal approval prior to engagement if they are expected to be for amounts under
$10,000 but greater than $5,000; and (iii) reported to the Audit Committee at
the next Audit Committee meeting if they are expected to be for an amount under
$5,000.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

The registrant's Board of Directors or Trustees has a separately designated
Audit Committee established in accordance with Section 3(a)(58)(A) of the
Securities Exchange Act of 1934, as amended (15 U.S.C. 78c(a)(58)(A)). The
members of the audit committee are Robert P. Bremner, Lawrence H. Brown, Jack B.
Evans, William J. Schneider, Eugene S. Sunshine and effective January 1, 2007,
David J. Kundert.

ITEM 6. SCHEDULE OF INVESTMENTS.

See Portfolio of Investments in Item 1.

ITEM 7.  DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

The registrant invests its assets primarily in municipal bonds and cash
management securities. On rare occasions the registrant may acquire, directly or
through a special purpose vehicle, equity securities of a municipal bond issuer
whose bonds the registrant already owns when such bonds have deteriorated or are
expected shortly to deteriorate significantly in credit quality. The purpose of
acquiring equity securities generally will be to acquire control of the
municipal bond issuer and to seek to prevent the credit deterioration or
facilitate the liquidation or other workout of the distressed issuer's credit
problem. In the course of exercising control of a distressed municipal issuer,
NAM may pursue the registrant's interests in a variety of ways, which may entail
negotiating and executing consents, agreements and other arrangements, and
otherwise influencing the management of the issuer. NAM does not consider such
activities proxy voting for purposes of Rule 206(4)-6 under the 1940 Act, but
nevertheless provides reports to the registrant's Board of Trustees on its
control activities on a quarterly basis.

In the rare event that a municipal issuer were to issue a proxy or that the
registrant were to receive a proxy issued by a cash management security, NAM
would either engage an independent third party to determine how the proxy should
be voted or vote the proxy with the consent, or based on the instructions, of
the registrant's Board of Trustees or its representative. A member of NAM's
legal department would oversee the administration of the voting, and ensure that
records were maintained in accordance with Rule 206(4)-6, reports were filed
with the SEC on Form N-PX, and the results provided to the registrant's Board of
Trustees and made available to shareholders as required by applicable rules.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

THE PORTFOLIO MANAGER

The following individual has primary responsibility for the day-to-day
implementation of the registrant's investment strategies:

NAME               FUND
Thomas Spalding    Nuveen Select Tax-Free Income Portfolio

Other Accounts Managed. In addition to managing the registrant, the portfolio
manager is also primarily responsible for the day-to-day portfolio management of
the following accounts:


                          TYPE OF ACCOUNT                       NUMBER OF
PORTFOLIO MANAGER             MANAGED                           ACCOUNTS      ASSETS
--------------------------------------------------------------------------------------------
                                                                     
Thomas Spalding    Registered Investment Company                11            $9,730 million
                   Other Pooled Investment Vehicles no change   -0-           $0
                   Other Accounts                               5             $11 million

*    Assets are as of March 31, 2007. None of the assets in these accounts are
     subject to an advisory fee based on performance.

Compensation. Each portfolio manager's compensation consists of three basic
elements--base salary, cash bonus and long-term incentive compensation. The
compensation strategy is to annually compare overall compensation, including
these three elements, to the market in order to create a compensation structure
that is competitive and consistent with similar financial services companies. As
discussed below, several factors are considered in determining each portfolio
manager's total compensation. In any year these factors may include, among
others, the effectiveness of the investment strategies recommended by the
portfolio manager's investment team, the investment performance of the accounts
managed by the portfolio manager, and the overall performance of Nuveen
Investments, Inc. (the parent company of the Adviser). Although investment
performance is a factor in determining the portfolio manager's compensation, it
is not necessarily a decisive factor The portfolio manager's performance is
evaluated in part by comparing manager's performance against a specified
investment benchmark. This fund-specific benchmark is a customized subset
(limited to bonds in each Fund's specific state and with certain maturity
parameters) of the S&P/Investortools Municipal Bond index, an index comprised of
bonds held by managed municipal bond fund customers of Standard & Poor's
Securities Pricing, Inc. that are priced daily and whose fund holdings aggregate
at least $2 million. As of April 30, 2007, the S&P/Investortools Municipal Bond
index was comprised of 50,300 securities with an aggregate current market value
of $ 985,620.

Base salary. Each portfolio manager is paid a base salary that is set at a level
determined by the Adviser in accordance with its overall compensation strategy
discussed above. The Adviser is not under any current contractual obligation to
increase a portfolio manager's base salary.

Cash bonus. Each portfolio manager is also eligible to receive an annual cash
bonus. The level of this bonus is based upon evaluations and determinations made
by each portfolio manager's supervisors, along with reviews submitted by his
peers. These reviews and evaluations often take into account a number of
factors, including the effectiveness of the investment strategies recommended to
the Adviser's investment team, the performance of the accounts for which he
serves as portfolio manager relative to any benchmarks established for those
accounts, his effectiveness in communicating investment performance to
stockholders and their representatives, and his contribution to the Adviser's
investment process and to the execution of investment strategies. The cash bonus
component is also impacted by the overall performance of Nuveen Investments,
Inc. in achieving its business objectives.

Long-term incentive compensation. Each portfolio manager is eligible to receive
bonus compensation in the form of equity-based awards issued in securities
issued by Nuveen Investments, Inc. The amount of such compensation is dependent
upon the same factors articulated for cash bonus awards but also factors in his
long-term potential with the firm.

Material Conflicts of Interest. Each portfolio manager's simultaneous management
of the Fund and the other accounts noted above may present actual or apparent
conflicts of interest with respect to the allocation and aggregation of
securities orders placed on behalf of the Fund and the other account. The
Adviser, however, believes that such potential conflicts are mitigated by the
fact that the Adviser has adopted several policies that address potential
conflicts of interest, including best execution and trade allocation policies
that are designed to ensure (1) that portfolio management is seeking the best
price for portfolio securities under the circumstances, (2) fair and equitable
allocation of investment opportunities among accounts over time and (3)
compliance with applicable regulatory requirements. All accounts are to be
treated in a non-preferential manner, such that allocations are not based upon
account performance, fee structure or preference of the portfolio manager. In
addition, the Adviser has adopted a Code of Conduct that sets forth policies
regarding conflicts of interest.

Beneficial Ownership of Securities. As of the March 31, 2007, the portfolio
manager beneficially owned the following dollar range of equity securities
issued by the Fund and other Nuveen Funds managed by NAM's municipal investment
team.
