Nuveen Investments Municipal Closed-End Funds
(NPC, NCL, NCU, NAC, NVX, NZH, NKL, NKX)

Portfolio Manager's
        COMMENTS


Portfolio manager Scott Romans discusses key investment strategies and the
six-month performance of these eight closed-end Nuveen California Funds. Scott,
who joined Nuveen in 2000, has managed NCU, NAC, NVX, NZH, NKL and NKX since
2003. He assumed portfolio management responsibility for NPC and NCL in 2005.


WHAT KEY STRATEGIES WERE USED TO MANAGE THE CALIFORNIA FUNDS DURING THE
SIX-MONTH REPORTING PERIOD ENDED FEBRUARY 28, 2007?

During this six-month period, we saw a modest increase in short-term interest
rates, while longer-term rates continued to decline, resulting in further
flattening of the yield curve. In this environment, where the yield curve
remained the dominant market factor, we continued to emphasize a disciplined
approach to duration1 management and yield curve positioning. As part of this
approach, our purchases for the Funds' portfolios focused mainly on attractively
priced bonds in the 20-year to 30-year part of the yield curve. We believed that
bonds in this part of the curve generally offered better value and reward
opportunities more commensurate with their risk levels. To help us maintain the
Funds' durations within our preferred strategic range, we also selectively sold
holdings with shorter durations, including pre-refunded bonds and bonds with
short maturities.

Our duration management strategies during this period also included the purchase
of inverse floating rate trusts, a type of derivative financial instrument, in
all eight of these California Funds. The inverse floaters had the dual benefit
of increasing the Funds' distributable income and bringing their durations
closer to our preferred strategic target. In past shareholder reports, we also
have discussed the use of other derivatives as a duration management tool. Going
into this reporting period, four of these California Funds--NPC, NCL, NAC and
NVX--were using forward interest rate swaps to help manage net asset value (NAV)
volatility. NAC also had purchased a small number of U.S. Treasury note futures
contracts. As of February 28, 2007, these four Funds continued to use these
derivatives, although we reduced the positions in NCL during this six-month
period. (NCU, NZH, NKL and NKX did not use swaps during this period because we
believed the durations of these Funds were adequately positioned relative to the
general market.)

Overall, portfolio activity was relatively light during much of this period due
to the fact that the rate environment was not advantageous for active trading.
In watching the market for opportunities to add value to our portfolios, we
focused mainly on premium


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.

coupon - typically 5% bonds priced to 10-year calls. As the bond market
continued to rally, especially in November and December 2006, we also purchased
bonds with coupons in the 4% range which typically offered higher income.

We also continued to emphasize maintaining weightings of lower credit quality
bonds in the four uninsured Funds (NCU, NAC, NVX, and NZH) and in NKL and NKX
(which can invest up to 20% of their assets in uninsured investment-grade
quality securities). We generally saw fewer attractively priced lower-rated
credit offerings in the California market. Although California remained the
largest state issuer of municipal debt in the nation, much of the new supply
during this period was insured, and we did not find many opportunities outside
the insured sector. Apart from credit, one area of the market in which we did
continue to find value was the single family housing sector, where we purchased
bonds for all four of the uninsured Funds as well as NKL.

For the six months ended February 28, 2007, the cumulative returns on NAV for
NCU, NAC and NZH outperformed the return on the Lehman Brothers California
Tax-Exempt Bond Index while NVX performed in line. The six-month returns for all
four of the Funds underperformed the average return of the Lipper California
peer group for this period. Among the insured Funds, NKL and NKX exceeded the
return on the Lehman Brothers Insured California Tax-Exempt Bond Index, while
NPC and NCL performed in line with this index return. NKX outperformed the
average return for the Lipper Insured California peer group, while NPC, NCL and
NKL trailed this group average.

Factors that influenced the Funds' returns during this period included duration
management, exposure to lower-rated credits (or credit risk) in the four
uninsured Funds, as well as NKL, and NKX, sector allocations, the relative
amount of advance refunding activity5, and the use of financial leverage.

As the yield curve continued to flatten over the course of this period, bonds
with longer duration structures, including zero coupon and non-callable bonds,
generally outperformed shorter duration bonds. Overall, these Funds were
strategically well positioned in terms of duration, as our careful approach to
duration management--including the use of inverse floaters and interest rate
swaps--kept the Funds' durations close to their preferred range.

With bonds rated BBB or lower and nonrated bonds generally outperforming other
credit quality sectors during this period, the four uninsured Funds as well as
NKL and NKX



4    The Lipper Insured California Municipal Debt Funds average is calculated
     using the returns of all closed-end funds in its category for each period
     as follows: 6 months, 13; 1 year, 13; 5 years, 8; and 10 years, 6. Fund and
     Lipper returns assume reinvestment of dividends.

5    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.


                                       6



(which can invest up to 20% of their assets in uninsured investment-grade
quality securities) benefited from their allocations to lower-quality credits.
The performance of this sector was largely the result of investor demand for the
higher yields typically associated with lower-rated bonds, which drove up their
value. (NPC and NCL, as 100% insured Funds, cannot hold any lower-rated
credits.)

Among the lower-rated holdings making contributions to the returns of NCU, NAC,
NVX, NZH, NKL and NKX were health care (including hospitals) credits and
industrial development revenue bonds, which ranked as the top performing revenue
sectors in the national Lehman Brothers Municipal Bond Index for this period.
Bonds backed by the 1998 master tobacco settlement agreement, which comprised
approximately 2% to 6% of the portfolios of these six Funds as of February 28,
2007, also performed well during this period.

We also continued to see positive contributions from advance refunding activity,
which benefited these Funds through price appreciation and enhanced credit
quality. Some of the performance differential among these eight Funds can be
attributed to the relative amounts of advance refundings they experienced during
this period, with NVX having the fewest bonds pre-refunded (as a percentage of
its portfolio) among the uninsured Funds. Among the insured Funds, NKX had more
than three times the amount of advance refundings than the other three insured
Funds.

At the same time, holdings of older, previously pre-refunded bonds tended to
underperform the general municipal market during this period, due primarily to
their shorter effective maturities and higher credit quality. Among these eight
Funds, NAC and NVX had the heaviest allocations of pre-refunded bonds entering
into this period.

Another factor in the six-month performance of these Funds, especially relative
to the performances of the unleveraged Lehman Brothers California Tax-Exempt
Bond Index and Lehman Brothers Insured California Tax-Exempt Bond Index, was the
use of financial leverage. While leverage can add volatility to a Fund's NAV and
share price, this strategy can also provide opportunities for additional income
and total return for common shareholders. Over this period, our leveraging
strategy had a positive impact on the results of these eight Funds.

All of the Funds in this report seek to pay stable dividends at rates that
reflect each Fund's past results and projected future performance. During
certain periods, each Fund may pay dividends at a rate that may be more or less
than the amount of net investment income actually earned by the Fund during the
period. If a Fund 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 Fund's NAV. Conversely, if a Fund has cumulatively paid dividends in
excess of its earnings, the excess constitutes negative UNII that is likewise
reflected in the Fund's NAV. Each Fund will, over time, pay all of its net
investment income as dividends to shareholders. As of February 28, 2007, NPC and
NCL had positive UNII balances for both financial statement and, based on our
best estimates, tax purposes, while the other six Funds had negative UNII
balances for financial statement purposes and positive UNII balances, based on
our best estimates, for tax purposes.

====================================================================================================================================
USD-LIBOR (United States Dollar-London Inter-Bank Offered Rate)

                    (1)  All percentages shown in the Portfolio of Investments
                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Optional Call Provisions: Dates (month and year) and
                         prices of the earliest optional call or redemption.
                         There may be other call provisions at varying prices at
                         later dates. Certain mortgage-backed securities may be
                         subject to periodic principal paydowns.

                    (3)  Ratings: Using the higher of Standard & Poor's or
                         Moody's rating. Ratings below BBB by Standard & Poor's
                         Group or Baa by Moody's Investor Service, Inc. are
                         considered to be below investment grade.

                    (4)  Backed by an escrow or trust containing sufficient U.S.
                         Government or U.S. Government agency securities which
                         ensure the timely payment of principal and interest.
                         Such investments are normally considered to be
                         equivalent to AAA rated securities.

                    (5)  Investment has a maturity of more than one year, but
                         has variable rate and demand features which qualify it
                         as a short-term investment. The rate disclosed is that
                         in effect at the end of the reporting period. This rate
                         changes periodically based on market conditions or a
                         specified market index.

                    (6)  Effective date represents the date on which both the
                         Fund and counterparty commence interest payment
                         accruals on each forward swap contract.

                    (7)  Portion of investments, with an aggregate market value
                         of $93,333 has been pledged to collateralize the net
                         payment obligations under futures contracts.

USD-LIBOR (United States Dollar-London Inter-Bank Offered Rate)

                    (1)  All percentages shown in the Portfolio of Investments
                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Optional Call Provisions: Dates (month and year) and
                         prices of the earliest optional call or redemption.
                         There may be other call provisions at varying prices at
                         later dates. Certain mortgage-backed securities may be
                         subject to periodic principal paydowns.

                    (3)  Ratings: Using the higher of Standard & Poor's or
                         Moody's rating. Ratings below BBB by Standard & Poor's
                         Group or Baa by Moody's Investor Service, Inc. are
                         considered to be below investment grade.

                    (4)  Backed by an escrow or trust containing sufficient U.S.
                         Government or U.S. Government agency securities which
                         ensure the timely payment of principal and interest.
                         Such investments are normally considered to be
                         equivalent to AAA rated securities.

                    (5)  Effective date represents the date on which both the
                         Fund and counterparty commence interest payment
                         accruals on each forward swap contract.

                         has variable rate and demand features which qualify it

                         in effect at the end of the reporting period. This rate
                         changes periodically based on market conditions or a
                         specified market index.

                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Optional Call Provisions: Dates (month and year) and
                         prices of the earliest optional call or redemption.
                         There may be other call provisions at varying prices at
                         later dates. Certain mortgage-backed securities may be
                         subject to periodic principal paydowns.

                    (3)  Ratings: Using the higher of Standard & Poor's or
                         Moody's rating. Ratings below BBB by Standard & Poor's
                         Group or Baa by Moody's Investor Service, Inc. are
                         considered to be below investment grade.

                    (4)  Backed by an escrow or trust containing sufficient U.S.
                         Government or U.S. Government agency securities which
                         ensure the timely payment of principal and interest.
                         Such investments are normally considered to be
                         equivalent to AAA rated securities.

                    (5)  Investment has a maturity of more than one year, but
                         has variable rate and demand features which qualify it
                         as a short-term investment. The rate disclosed is that
                         in effect at the end of the reporting period. This rate
                         changes periodically based on market conditions or a
                         specified market index.

                    N/R  Not rated.

                  WI/DD  Purchased on a when-issued or delayed delivery basis.

                   (UB)  Underlying bond of an inverse floating rate trust

                         provisions of SFAS No. 140.

1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

The California funds (the "Funds") covered in this report and their
corresponding Common share stock exchange symbols are Nuveen Insured California
Premium Income Municipal Fund, Inc. (NPC), Nuveen Insured California Premium
Income Municipal Fund 2, Inc. (NCL), Nuveen California Premium Income Municipal
Fund (NCU), Nuveen California Dividend Advantage Municipal Fund (NAC), Nuveen
California Dividend Advantage Municipal Fund 2 (NVX), Nuveen California Dividend
Advantage Municipal Fund 3 (NZH), Nuveen Insured California Dividend Advantage
Municipal Fund (NKL) and Nuveen Insured California Tax-Free Advantage Municipal
Fund (NKX). Common shares of Insured California Premium Income (NPC), Insured
California Premium Income 2 (NCL) and California Dividend Advantage (NAC) are
traded on the New York Stock Exchange while Common shares of California Premium
Income (NCU), California Dividend Advantage 2 (NVX), California Dividend
Advantage 3 (NZH), Insured California Dividend Advantage (NKL) and Insured
California Tax-Free Advantage (NKX) are traded on the American Stock Exchange.
The Funds are registered under the Investment Company Act of 1940, as amended,
as closed-end management investment companies.

Each Fund seeks to provide current income exempt from both regular federal and
California state income taxes, and in the case of Insured California Tax-Free
Advantage (NKX) the alternative minimum tax applicable to individuals, by
investing primarily in a diversified portfolio of municipal obligations issued
by state and local government authorities within the state of California or
certain U.S. territories.

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 Directors/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. Prices of forward swap contacts are also provided by an independent
pricing service approved by each Fund's Board of Directors/Trustees. Futures
contracts are valued using the closing settlement price, or, in the absence or
such a price, at the mean of the bid and asked prices. If the pricing service is
unable to supply a price for a municipal bond, forward swap contract or futures
contact, 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 Directors/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 February 28, 2007,
California Dividend Advantage (NAC), California Dividend Advantage 3 (NZH),
Insured California Dividend Advantage (NKL) and Insured California Tax-Free
Advantage (NKX) had outstanding when-issued/delayed delivery purchase
commitments of $9,696,417, $12,793,810, $6,396,905 and $2,132,302, respectively.
There were no such outstanding purchase commitments in any of the other 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 California state
income taxes, and in the case of Insured California Tax-Free Advantage (NKX) the
alternative minimum tax applicable to individuals, 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.


                                       70



Dividends and Distributions to Common 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 Common 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.

Preferred Shares

The Funds have issued and outstanding Preferred shares, $25,000 stated value per
share, as a means of effecting financial leverage. Each Fund's Preferred shares
are issued in one or more Series. The dividend rate paid by the Funds on each
Series is determined every seven days, pursuant to a dutch auction process
overseen by the auction agent, and is payable at the end of each rate period.
The number of Preferred shares outstanding, by Series and in total, for each
Fund is as follows:

Insurance

Insured California Premium Income (NPC) and Insured California Premium Income 2
(NCL) invest only in municipal securities which are either covered by insurance
or are backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest.

Insured California Dividend Advantage (NKL) and Insured California Tax-Free
Advantage (NKX) invest at least 80% of their net assets (including net assets
attributable to Preferred shares) in municipal securities that are covered by
insurance. Each Fund may also invest up to 20% of its net assets (including net
assets attributable to Preferred shares) in municipal securities which are
either (i) backed by an escrow or trust containing sufficient U.S. Government or
U.S. Government agency securities, or (ii) rated, at the time of investment,
within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch)
or unrated but judged to be of comparable quality by the Adviser.

Each insured municipal security is covered by Original Issue Insurance,
Secondary Market Insurance or Portfolio Insurance. Such insurance does not
guarantee the market value of the municipal securities or the value of the
Funds' Common shares. Original Issue Insurance and Secondary Market Insurance
remain in effect as long as the municipal securities covered thereby remain
outstanding and the insurer remains in business, regardless of whether the Funds
ultimately dispose of such municipal securities. Consequently, the market value
of the municipal securities covered by Original Issue Insurance or Secondary
Market Insurance may reflect value attributable to the insurance. Portfolio
Insurance, in contrast, is effective only while the municipal securities are
held by the Funds. Accordingly, neither the prices used in determining the
market value of the underlying municipal securities nor the Common share net
asset value of the Funds include value, if any, attributable to the Portfolio
Insurance. Each policy of the Portfolio Insurance does, however, give the Funds
the right to obtain permanent insurance with respect to the municipal security
covered by the Portfolio Insurance policy at the time of its sale.

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


                                       71


Notes to
    FINANCIAL STATEMENTS (Unaudited) (continued)



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 six months ended February 28, 2007, each Fund invested in externally
deposited inverse floaters and/or self-deposited inverse floaters.

The average floating rate obligations outstanding and average annual interest
rate and fees related to self-deposited inverse floaters during the six months
ended February 28, 2007, were as follows:

Forward Swap Transactions

The Funds are authorized to invest in certain derivative financial instruments.
Each Fund's use of forward interest rate swap transactions is intended to help
the Fund manage its overall interest rate sensitivity, either shorter or longer,
generally to more closely align the Fund's interest rate sensitivity with that
of the broader municipal market. Forward interest rate swap transactions involve
each Fund's agreement with a counterparty to pay, in the future, a fixed or
variable rate payment in exchange for the counterparty paying the Fund a
variable or fixed rate payment, the accruals for which would begin at a
specified date in the future (the "effective date"). The amount of the payment
obligation is based on the notional amount of the forward swap contract and the
termination date of the swap (which is akin to a bond's maturity). The value of
the Fund's swap commitment would increase or decrease based primarily on the
extent to which long-term interest rates for bonds having a maturity of the
swap's termination date increases or decreases. The


                                       72



Funds may terminate a swap contract prior to the effective date, at which point
a realized gain or loss is recognized. When a forward swap is terminated, it
ordinarily does not involve the delivery of securities or other underlying
assets or principal, but rather is settled in cash on a net basis. Each Fund
intends, but is not obligated, to terminate its forward swaps before the
effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Fund upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of each Fund with a value approximately equal to the amount of any
unrealized gain above a pre-determined threshold. Reciprocally, when any of the
Funds have an unrealized loss on a swap contract, the Funds have instructed the
custodian to pledge assets of the Funds as collateral with a value approximately
equal to the amount of the unrealized loss above a pre-determined threshold.
Collateral pledges are monitored and subsequently adjusted if and when the swap
valuations fluctuate, either up or down, by at least the predetermined threshold
amount.

Futures Contracts

The Funds are authorized to invest in futures contracts. Upon entering into a
futures contract, a Fund is required to deposit with the broker an amount of
cash or liquid securities equal to a specified percentage of the contract
amount. This is known as the "initial margin." Subsequent payments ("variation
margin") are made or received by a Fund each day, depending on the daily
fluctuation of the value of the contract.

During the period the futures contract is open, changes in the value of the
contract are recognized as an unrealized gain or loss by "marking-to-market" on
a daily basis to reflect the changes in market value of the contract. When the
contract is closed or expired, a Fund records a realized gain or loss equal to
the difference between the value of the contract on the closing date and value
of the contract when originally entered into. Cash held by the broker to cover
initial margin requirements on open futures contracts, if any, is noted in the
Statement of Assets and Liabilities. Additionally, the Statement of Assets and
Liabilities reflects a receivable or payable for the variation margin when
applicable.

Risks of investments in futures contracts include the possible adverse movement
of the securities or indices underlying the contracts, the possibility that
there may not be a liquid secondary market for the contracts and/or that a
change in the value of the contract may not correlate with a change in the value
of the underlying securities or indices.

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 Directors/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 applicable to Common shares 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 February 28, 2007, the cost of investments was as follows:

Insured California Premium Income 2 (NCL) elected to defer net realized losses
from investments incurred from November 1, 2005 through August 31, 2006

Post-October losses of $18,677 were treated as having arisen on the first day of
the current fiscal year.

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.


                                       76



The annual fund-level fee, payable monthly, for each Fund is based upon the
average daily net assets (including net assets attributable to Preferred shares)
of each Fund as follows:

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

(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

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 Directors/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
Directors/Trustees has adopted a deferred compensation plan for independent
Directors/Trustees that enables Directors/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.

For the first ten years of California Dividend Advantage's (NAC) operations, the
Adviser has agreed to reimburse the Fund, as a percentage of average daily net
assets (including net assets attributable to Preferred shares), for fees and

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 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 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 August 31, 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 February 28, 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.

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
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. 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.

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.

Automatic Dividend
     REINVESTMENT PLAN

NOTICE OF AMENDMENT TO THE TERMS AND CONDITIONS

These Funds are amending the terms and conditions of their Automatic Dividend
Reinvestment Plan (the ''Plan'') as further described below effective with the
close of business on June 1, 2007. THESE CHANGES ARE INTENDED TO ENABLE PLAN
PARTICIPANTS UNDER CERTAIN CIRCUMSTANCES TO REINVEST FUND DISTRIBUTIONS AT A
LOWER AGGREGATE COST THAN IS POSSIBLE UNDER THE EXISTING PLAN. Shareholders who
do not wish to continue as participants under the amended Plan may withdraw from
the Plan by notifying the Plan Agent prior to the effective date of the
amendments. Participants should refer to their Plan document for notification
instructions, or may simply call Nuveen at (800) 257-8787.

Fund shareholders who elect to participate in the Plan are able to have Fund
distributions consisting of income dividends, realized capital gains and returns
of capital automatically reinvested in additional Fund shares. Under the Plan's
existing terms, the Plan Agent purchases Fund shares in the open market if the
Fund's shares are trading at a discount to their net asset value on the payable
date for the distribution. If the Fund's shares are trading at or above their
net asset value on the payable date for the distribution, the Plan Agent
purchases newly-issued Fund shares directly from the Fund at a price equal to
the greater of the shares' net asset value or 95% of the shares' market value.

Under the Plan's amended terms, 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. This change will permit Plan
participants under these circumstances to reinvest Fund distributions at a lower
aggregate cost than is possible under the existing Plan.

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.
