INVESTMENT ADVISER NAME CHANGE
 
Effective January 1, 2011, Nuveen Asset Management, the Funds’ investment adviser, changed its name to Nuveen Fund Advisors, Inc. (“Nuveen Fund Advisors”). Concurrently, Nuveen Fund Advisors formed a wholly-owned subsidiary, Nuveen Asset Management, LLC, to house its portfolio management capabilities.
 
NUVEEN INVESTMENTS COMPLETES STRATEGIC COMBINATION WITH FAF ADVISORS
 
On December 31, 2010, Nuveen Investments completed the strategic combination between Nuveen Asset Management, LLC, the largest investment affiliate of Nuveen Investments, and FAF Advisors. As part of this transaction, U.S. Bancorp – the parent of FAF Advisors – received cash consideration and a 9.5% stake in Nuveen Investments in exchange for the long term investment business of FAF Advisors, including investment management responsibilities for the non-money market mutual funds of the First American Funds family. 
 
The approximately $27 billion of mutual fund and institutional assets managed by FAF Advisors, along with the investment professionals managing these assets and other key personnel, have become part of Nuveen Asset Management, LLC. With these additions to Nuveen Asset Management, LLC, this affiliate now manages more than $100 billion of assets across a broad range of strategies from municipal and taxable fixed income to traditional and specialized equity investments.
 
This combination does not affect the investment objectives or strategies of the Funds in this report. Over time, Nuveen Investments expects that the combination will provide even more ways to meet the needs of investors who work with financial advisors and consultants by enhancing the multi-boutique model of Nuveen Investments, which also includes highly respected investment teams at HydePark, NWQ Investment Management, Santa Barbara Asset Management, Symphony Asset Management, Tradewinds Global Investors and Winslow Capital. Nuveen Investments managed approximately $206 billion of assets as of March 31, 2011.

Chairman’s
Letter to Shareholders
 
 
Dear Shareholders,
 
In 2010, the global economy recorded another year of recovery from the financial and economic crises of 2008, but many of the factors that caused the downturn still weigh on the prospects for continued improvement. In the U.S., ongoing weakness in housing values has put pressure on homeowners and mortgage lenders. Similarly, the strong earnings recovery for corporations and banks is only slowly being translated into increased hiring or more active lending. Globally, deleveraging by private and public borrowers has inhibited economic growth and that process is far from complete.
 
Encouragingly, constructive actions are being taken by governments around the world to deal with economic issues. In the U.S., the recent passage of a stimulatory tax bill relieved some of the pressure on the Federal Reserve to promote economic expansion through quantitative easing and offers the promise of sustained economic growth. A number of European governments are undertaking programs that could significantly reduce their budget deficits. Governments across the emerging markets are implementing various steps to deal with global capital flows without undermining international trade and investment.
 
The success of these government actions could determine whether 2011 brings further economic recovery and financial market progress. One risk associated with the extraordinary efforts to strengthen U.S. economic growth is that the debt of the U.S. government will continue to grow to unprecedented levels. Another risk is that over time there could be inflationary pressures on asset values in the U.S. and abroad, because what happens in the U.S. impacts the rest of the world economy. Also, these various actions are being taken in a setting of heightened global economic uncertainty, primarily about the supplies of energy and other critical commodities. In this challenging environment, your Nuveen investment team continues to seek sustainable investment opportunities and to remain alert to potential risks in a recovery still facing many headwinds. On your behalf, we monitor their activities to assure they maintain their investment disciplines.
 
As you will note elsewhere in this report, on December 31, 2010, Nuveen Investments completed a strategic combination with FAF Advisors, Inc., the manager of the First American Funds. The combination adds highly respected and distinct investment teams to meet the needs of investors and their advisors and is designed to benefit all fund shareholders by creating a fund organization with the potential for further economies of scale and the ability to draw from even greater talent and expertise to meet those investor needs.
 
As of the end of April, 2011, Nuveen Investments had completed the refinancing of all of the Auction Rate Preferred Securities issued by its taxable closed-end funds and 89% of the MuniPreferred shares issued by its tax-exempt closed-end funds. Please consult the Nuveen Investments web site, www.Nuveen.com, for the current status of this important refinancing program.
 
As always, I encourage you to contact your financial consultant if you have any questions about your investment in a Nuveen Fund. On behalf of the other members of your Fund Board, we look forward to continuing to earn your trust in the months and years ahead.
 
Sincerely,

Portfolio Manager’s Comments
 
Nuveen Build America Bond Fund (NBB)
Nuveen Build America Bond Opportunity Fund (NBD)
 
Portfolio manager Daniel Close discusses U.S. economic and municipal market conditions, key investment strategies and the performance of the Nuveen Build America Bond Fund (NBB) and the Nuveen Build America Bond Opportunity Fund (NBD). Dan, who joined Nuveen in 2000, has managed NBB since its inception in April 2010 and NBD since its inception in November 2010.
 
What factors affected the U.S. economy and municipal market during the reporting period ended March 31, 2011?
 
During this period, the U.S. economy demonstrated some signs of improvement, supported by the efforts of both the Federal Reserve (Fed) and the federal government. For its part, the Fed continued to hold the benchmark fed funds rate in a target range of zero to 0.25% since cutting it to this record low level in December 2008. At its April 2011 meeting (following the end of this reporting period), the central bank renewed its commitment to keeping the fed funds rate at “exceptionally low levels” for an “extended period.” The Fed also left unchanged its second round of quantitative easing, which calls for purchasing $600 billion in longer-term U.S. Treasury bonds by June 30, 2011. The goal of this plan is to lower long-term interest rates and thereby stimulate economic activity and create jobs. The federal government continued to focus on implementing the economic stimulus package passed in early 2009 aimed at providing job creation, tax relief, fiscal assistance to state and local governments and expansion of unemployment benefits and other federal social welfare programs.
 
In the first quarter of 2011, the U.S. economy, as measured by the U.S. gross domestic product (GDP), grew at an annualized rate of 1.8%, marking the seventh consecutive quarter of positive growth. The employment picture continued to improve gradually, with the national jobless rate registering 8.8% in March 2011, its lowest level since March 2009 and down from 9.7% a year earlier. While the Fed’s longer-term inflation expectations remained stable, inflation posted its largest twelve month gain since December 2009, as the Consumer Price Index (CPI) rose 2.7% year-over-year as of March 2011, driven mainly by increased prices for energy. The core CPI (which excludes food and energy) increased 1.2% over this period, staying within the Fed’s unofficial objective of 2.0% or lower for this measure. The housing market continued to be a weak spot in the economy. For the twelve months ended February 2011 (most recent data available at the time this report was prepared), the average home price in the Standard & Poor’s (S&P) Case-Shiller index of 20 major metropolitan areas lost 3.3%, with 10 of the 20 metropolitan areas hitting their lowest levels since housing prices peaked in 2006.

Looking at the overall municipal market, bond prices generally rose during this period, as the combination of strong demand and tight supply of new tax-exempt issuance created favorable market conditions. After rallying strongly over most of the period, the municipal market suffered a reversal in mid-November 2010, due largely to investor concerns about inflation, the federal deficit and the deficit’s impact on demand for U.S. Treasuries. Adding to this situation was media coverage of the strained finances of many state and local governments, which often failed to differentiate between gaps in these governments’ operating budgets and their ability to meet their debt service obligation. Toward the end of this period, we saw the environment in the municipal market improve, as crossover buyers—including hedge funds and life insurance companies—were attracted by municipal bond prices and tax-exempt yields, resulting in decreased outflows, declining yields and rising valuations.
 
What key strategies were used to manage NBB and NBD during this period?
 
The inception date for NBB was April 27, 2010, and for NBD it was November 23, 2010. Both NBB and NBD are designed to invest primarily in Build America Bonds (BABs) and other taxable municipal bonds. Bonds issued under the Build America Bond program, which ended December 31, 2010, offered municipal issuers a federal subsidy equal to 35% of a bond’s interest payments, often providing issuers with a lower-cost alternative to traditional tax-exempt debt.
 
The primary investment objective of these two Funds is to provide current income through investments in taxable municipal securities. Their secondary objective is to seek enhanced portfolio value and total return. The Funds offer strategic portfolio diversification opportunities for traditional municipal bond investors, while broadening participation to investors that have not traditionally purchased municipal bonds, including public and corporate retirement plans, endowments, life insurance companies, and sovereign wealth funds. For these investors, these Funds can offer investment-grade municipal credit, current income, and strong call protection.
 
Both NBB and NBD completed their initial investment process during this reporting period. Between April 2010, when NBB was introduced, and the end of the BAB program in December 2010, BAB issuance totaled $90.5 billion. Issuance was particularly heavy during the fourth quarter of 2010, as issuers uncertain about the extension of the BAB program sought to take advantage of the program’s terms before it expired. During this period, $44.1 billion in BABs were issued, accounting for 33% of new bonds issued in the municipal market. Within the 21 months between the first BAB issue in April 2009 and the last BAB issue in December 2010, $181.4 billion of Build America Bonds were issued. The secondary market for BABs continues to be active.
 
The ample supply of BAB issuance during the invest-up enabled us to purchase a good balance of BABs in both the primary (new issue) and secondary markets. Under the provisions of the Build America Bond program, only governmental entities could issue BABs. Issuance was heaviest in the general purpose/public improvement, education, transportation, and utilities sectors. Nonprofit 501(c)(3) organizations such as hospitals generally did not qualify as BABs issuers, limiting the availability of these bonds. Bonds with proceeds

earmarked for refundings, working capital and private activities also were not covered by the BAB program. By the end of the program, all states except Montana and Rhode Island had issued BABs, with California, New York, Texas, Illinois and Ohio at the forefront in terms of issuance, followed by New Jersey, Washington, Pennsylvania, Florida and Georgia. This enabled us to add geographic diversity to the Funds. The majority of our purchases were at the long end of the yield curve.
 
During NBB’s invest-up period, we purchased a good mix of benchmark and non-benchmark BAB issues. Benchmark BAB issues are bonds whose cusip is over $250 million in size and therefore eligible for inclusion in the Barclays Capital Build America Bond (BAB) Index. Non-benchmark BAB issues are smaller, generally lower-profile issuers that can offer the same credit quality as benchmark issues, but may require a more detailed credit review before purchase. As part of its investment strategies, NBB uses an integrated leverage and hedging strategy to seek to enhance current income and total return, while working to maintain a level of interest rate risk similar to that of the Barclays Capital BAB Index. To implement leverage, NBB uses both bank borrowings and inverse floating rate securities. Duration shortening hedges, which can include shorting U.S. Treasury futures or long LIBOR swaps, were used to reduce the leverage-adjusted portfolio duration to a level close to that of the index. NBB’s integrated leverage strategy is discussed further on page nine.
 
After the completion of NBB’s invest-up period, we focused primarily on improving the Fund’s liquidity profile by purchasing additional benchmark, or index-eligible, BAB issues. These bonds, which were in good supply in the primary market during the fourth quarter of 2010, are currently in greater demand than non-benchmark issues and should be more liquid on a going-forward basis. Purchases were funded with the proceeds from sales of non-benchmark issues. Following the end of new issue BABs, we continued to sell non-benchmark and other non-BAB bonds and purchase BABs in the secondary market, focusing on adding benchmark issues where we had favorable credit opinions while these bonds were still readily available in the market.
 
During the last half of this period, we also shifted more of NBB’s leverage from bank borrowings to inverse floating rate securities. In our opinion, these securities currently offer a less expensive form of financing. NBB’s leverage, originally implemented as approximately 65% through borrowings and 35% through inverse floaters1, was approximately 80% funded by inverse floaters as of the end of this period.
 
In NBD, the heavy supply of new BABs during the last part of 2010 enabled us to complete the invest-up of this Fund primarily with purchases of BABs, with an emphasis on benchmark issues, and also to diversify NBD in terms of sector and credit. Shortly after the invest-up period began, we bought a number of long U.S. Treasury bonds to help bring NBD’s duration profile in line with that of the Fund’s benchmark, the Barclays Capital BAB Index. Toward the end of this period, we sold most of these non-BAB holdings and reinvested the proceeds in BABs. NBD uses a leverage strategy similar to that used in NBB using inverse floating rate securities only. Following the end of the new issue calendar, we continued to make small trades in the secondary market and worked to increase NBD’s liquidity. In early 2011, following a decline in the tax-exempt municipal market, both NBB and NBD purchased tax-exempt municipal bonds at attractive prices.

Inverse floating rate securities, also known as inverse floaters, 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.

As the valuations on these bonds approached more appropriate levels near the end of this period, we sold these non-BABs at higher prices, thus benefiting the Funds.
 
During the period, the Funds also entered into interest rate and forward interest rate swap contracts to reduce the duration of each Fund’s portfolio, as well as to partially fix its interest cost of leverage.
 
Because the BAB program was not renewed at the end of December 2010, shareholders should note that both NBB and NBD have contingent term provisions stating that if there are no new issuances of BABs or similarly U.S. Treasury-subsidized taxable municipal bonds for any 24-month period ending on or before December 31, 2014, NBB and NBD will terminate on or around June 30, 2020, and December 31, 2020, respectively.

For the period between their respective inceptions and March 31, 2011, the cumulative returns on net asset value (NAV) for NBB and NBD exceeded the returns for the Barclays Capital Build America Bond (BAB) Index, which reflect the same time periods.
 
Key management factors that influenced the Funds’ returns during this period included duration and yield curve positioning, credit exposure and sector allocation. In addition, individual security selection was positive for both NBB and NBD, as heavy issuance of BABs during the fourth quarter of 2010 gave us access to a robust array of bonds with attractive features from which to choose. The Funds’ use of leverage was an important factor affecting the Funds’ performance for this period. The impact of leverage is discussed in more detail on page nine.
 
During this period, bonds with intermediate and longer maturities generally performed well. Overall, duration was a positive contributor to NBB’s performance and a negative factor in NBD. This difference can be attributed to NBB’s overweighting of an intermediate segment of the yield curve that performed particularly well during this period.
 
Both NBB and NBD were similarly weighted among the credit quality sectors, with their largest allocation in bonds rated AA, followed by A, AAA, BBB and non-rated bonds. On the whole, this credit rating exposure was negative for performance during this period.
 
The overall impact of sector exposure was positive in both NBB and NBD. The Funds’ sector allocations were well diversified, with the heaviest weightings in limited and general tax obligation bonds, utilities, transportation and water and sewer credits.

IMPACT OF THE FUNDS’ LEVERAGE STRATEGIES ON PERFORMANCE
 
One important factor impacting the returns of these Funds relative to the comparative index was the Funds’ use of leverage. These Funds use leverage because their managers believe that, over time, leveraging provides opportunities for additional income and total return for shareholders. However, use of leverage also can expose shareholders to additional volatility. For example, as the prices of securities held by a Fund decline, the negative impact of these valuation changes on net asset value and total return is magnified by the use of leverage. Conversely, leverage may enhance returns during periods when the prices of securities held by the Funds’ generally are rising. Leverage made a positive contribution to the Funds’ performance over the reporting period.

Dividend and Share Price Information
 
Introduced in April 2010, NBB declared its initial monthly distribution in June 2010 and maintained a stable monthly dividend throughout the remainder of the reporting period ended March 31, 2011. NBD, which was introduced in November 2010, declared its initial monthly dividend distribution in January 2011 and maintained a stable monthly dividend over the remainder of the period.
 
NBB and NBD seek to pay stable dividends at rates that reflect the Funds’ past results and projected future performance. During certain periods, the Funds may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Funds 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. The Funds will, over time, pay all of their net investment income as dividends to shareholders. As of March 31, 2011, both NBB and NBD had positive UNII balances for both tax and financial reporting purposes.
 
SHARE REPURCHASES AND PRICE INFORMATION
 
Since the inception of NBB’s repurchase program, NBB has not repurchased any of its outstanding shares. As of March 31, 2011, NBD is not authorized to repurchase its outstanding shares.

Nuveen Build America Bond Fund
Nuveen Build America Bond Opportunity Fund
 
We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen Build America Bond Fund and Nuveen Build America Bond Opportunity Fund (the “Funds”) as of March 31, 2011, and the related statements of operations, changes in net assets, cash flows (Nuveen Build America Bond Fund only), and the financial highlights for the periods indicated therein. 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 audits 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, 2011, 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 Build America Bond Fund and Nuveen Build America Bond Opportunity Fund at March 31, 2011, and the results of their operations, changes in their net assets, their cash flows (Nuveen Build American Bond Fund only), and the financial highlights for the periods indicated therein in conformity with U.S. generally accepted accounting principles.

(a)
Per share Net Investment Income (Loss) is calculated using the average daily shares method.
(b)
Total Return Based on Market Value is the combination of changes in the market 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. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation.
 
Total returns are not annualized.
   
 
Total Return Based on Net Asset Value is the combination of changes in net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized.
(c)
Ratios do not reflect the effect of custodian fee credits earned on the Fund’s net cash on deposit with the custodian bank, where applicable.
(d)
Each ratio includes the effect of the interest expense and fees paid on borrowings, where applicable, as described in Footnote 8 – Borrowing Arrangements, as follows:

1. General Information and Significant Accounting Policies
 
General Information
The funds covered in this report and their corresponding New York Stock Exchange (“NYSE”) symbols are Nuveen Build America Bond Fund (NBB) and Nuveen Build America Bond Opportunity Fund (NBD) (collectively, the “Funds”). The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end, registered investment companies.
 
Effective January 1, 2011, the Funds’ adviser, Nuveen Asset Management, a wholly-owned subsidiary of Nuveen Investments, Inc. (“Nuveen”), changed its name to Nuveen Fund Advisors, Inc. (the “Adviser”). Concurrently, the Adviser formed a wholly-owned subsidiary, Nuveen Asset Management, LLC (the “Sub-Adviser”), to house its portfolio management capabilities and to serve as the Funds’ sub-adviser, and the Funds’ portfolio manager became an employee of the Sub-Adviser. This allocation of responsibilities between the Adviser and the Sub-Adviser affects both of the Funds. The Adviser will compensate the Sub-Adviser for the portfolio management services it provides to the Funds from each Fund’s management fee.
 
Prior to the commencement of operations, the Funds had no operations other than those related to organizational matters, the initial capital contribution of $100,275 to each Fund by the Adviser, and the recording of the organization expense ($11,000 per Fund) and their reimbursement by the Adviser.
 
Each Fund’s primary investment objective is to provide current income through investments in taxable municipal securities. Each Fund’s secondary investment objective is to seek enhanced portfolio value and total return. The Funds seek to achieve their investment objectives by investing primarily in a diversified portfolio of taxable municipal securities known as Build America Bonds (or “BABs”), which make up 80% of their managed assets (as defined in Footnote 7 – Management Fees and Other Transactions with Affiliates). BABs are taxable municipal securities that include bonds issued by state and local governments to finance capital projects such as public schools, roads, transportation infrastructure, bridges, ports and public buildings, among others, pursuant to the American Recovery and Reinvestment Act of 2009, which offer municipal issuers a federal subsidy equal to 35% of a bond’s interest payments. Under normal circumstances, the Funds may invest 20% of their managed assets in securities other than BABs, including taxable and tax-exempt municipal securities, U.S. Treasury and other U.S. government agency securities. At least 80% of each Fund’s managed assets will be invested in securities that are investment grade quality at the time of purchase, as rated by at least one independent rating agency or judged to be of comparable quality by the Sub-Adviser. In addition, each Fund will use an integrated leverage and hedging strategy that the Fund has the potential to enhance income and risk-adjusted total return over time. Each Fund may employ leverage instruments such as borrowings, including loans from certain financial institutions, and portfolio investments that have the economic effect of leverage, including investments in inverse floating rate securities. Each Fund’s overall goal is to outperform over time the Barclays Capital Build America Bond Index, an unleveraged index representing the BABs market, while maintaining a comparable overall level of interest rate risk.
 
The BAB program expired on December 31, 2010, and was not renewed. Build America Bond (NBB) and Build American Bond Opportunity (NBD) each have contingent term provisions stating that if there are no new issuances of BABs or similarly U.S. Treasury-subsidized taxable municipal bonds for any twenty-four month period ending on or before December 31, 2014, Build America Bond (NBB) and Build American Bond Opportunity (NBD) will terminate on or around June 30, 2020, and December 31, 2020, respectively.
 
Significant Accounting Policies
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 (“U.S. GAAP”).
 
Investment Valuation
Prices of municipal bonds and swap contracts are provided by a pricing service approved by the Funds’ Board of Trustees. These securities are generally classified as Level 2 for fair value measurement purposes. When price quotes are not readily available (which is usually the case for municipal bonds) the pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer, or market activity provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs.
 
32 Nuveen Investments
 
 
 

 
 

 
Repurchase agreements are valued at contract amount plus accrued interest, which approximates market value. These securities are generally classified as Level 2.
 
Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Funds’ Board of Trustees or its designee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s net asset value (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the priority of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Funds’ Board of Trustees or its designee.
 
Refer to Footnote 2 – Fair Value Measurements for further details on the leveling of securities held by the Funds as of the end of the reporting period.
 
Investment Transactions
Investment transactions are recorded on a trade date basis. Realized gains and losses from transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. 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, 2011, the Funds had no such outstanding purchase commitments.
 
Investment Income
Investment income, which reflects the amortization of premiums and includes accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also reflects 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 of its 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.
 
For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.
 
Dividends and Distributions to Shareholders
Dividends to shareholders are declared monthly. Net realized capital gains from investment transactions, if any, are distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.
 
Distributions to shareholders 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. GAAP.
 
Inverse Floating Rate Securities
Each Fund is authorized to 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.

Notes to
Financial Statements (continued)
 
 
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”). The inverse floater held by a Fund gives the Fund the right (a) to cause the holders of the floating rate certificates to tender their notes at par, and (b) to have the broker transfer the fixed-rate bond held by the trust to the Fund, thereby collapsing the trust. An investment in an externally-deposited inverse floater is identified in the Portfolio of Investments as “(IF) – Inverse floating rate investment.” An investment in a self-deposited inverse floater is accounted for as a financing transaction. In such instances, a fixed-rate bond deposited into a special purpose trust is identified in the Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” 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 the related interest paid to the holders of the short-term floating rate certificates as a component of “Interest expense” on the Statement of Operations.
 
During the period from each Fund’s commencement of operations through March 31, 2011, each Fund invested in externally-deposited inverse floaters and/or self-deposited inverse floaters.
 
Each Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a “recourse trust” or “credit recovery swap”) (such agreements referred to herein as “Recourse Trusts”) with a broker-dealer by which a Fund agrees to reimburse the broker-dealer, in certain circumstances, for the difference between the liquidation value of the fixed-rate bond held by the trust and the liquidation value of the floating rate certificates issued by the trust plus any shortfalls in interest cash flows. Under these agreements, a Fund’s potential exposure to losses related to or on inverse floaters may increase beyond the value of a Fund’s inverse floater investments as a Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates. At period end, any such shortfall is recognized as “Unrealized depreciation on Recourse Trusts” on the Statement of Assets and Liabilities.
 
     
At March 31, 2011, each Fund’s maximum exposure to externally-deposited Recourse Trusts, was as follows:

Swap Contracts
Each Fund is authorized to enter into interest rate swap and forward interest rate swap contracts consistent with their investment objectives and policies to reduce, increase or otherwise alter its risk profile or to alter its portfolio characteristics (i.e. duration, yield curve positioning and credit quality), and is subject to interest rate risk in the normal course of pursuing its investment objectives. Each Fund’s use of interest rate swap and 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 market.
 
Interest rate swap contracts involve each Fund’s agreement with the counterparty to pay or receive a fixed rate payment in exchange for the counterparty receiving or paying a variable rate payment. Forward interest rate swap transactions involve a Fund’s agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying a 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 on a swap contract is based on the notional amount and the termination date of the swap (which is akin to a bond’s maturity). The value of a Fund’s swap commitment will 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 increase or decrease. Interest rate swap and forward interest rate swap contracts are valued daily. Upon entering into an interest rate swap (and beginning on the effective date for a forward interest rate swap), each Fund accrues the fixed rate payment expected to be paid or received and the variable rate payment expected to be received or paid on a daily basis, and recognizes the daily change in the market value of the Fund’s contractual rights and obligations under the contracts. The net amount recorded on these transactions, for each counterparty is recognized on the Statement of Assets and
 
34 Nuveen Investments
 
 
 

 
 

 
Liabilities as a component of “Unrealized appreciation or depreciation on swaps” with the change during the fiscal period recognized on the Statement of Operations as a component of “Net unrealized appreciation (depreciation) of swaps.”
 
When an interest rate swap or forward interest rate swap contract 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. Once periodic payments are settled in cash, they are combined with the net realized gain or loss recorded upon the termination of the swap contracts. For tax purposes, periodic payments are treated as ordinary income or expense. Net realized gains and losses on swap contracts during the fiscal period are recognized on the Statement of Operations as a component of “Net realized gain (loss) from swaps.”
 
The Funds entered into interest rate and forward interest rate swap transactions to reduce the duration of each Fund’s portfolio as well as to fix its interest cost of leverage. The average notional amount of swap contracts outstanding during the period from each Fund’s commencement of operations through March 31, 2011, was as follows:
 
         
 
Build

Includes both interest rate and forward interest rate swaps. The average notional amount is calculated based on the outstanding notional at the beginning of the fiscal year and at the end of each fiscal quarter within the current fiscal year.
 
Refer to Footnote 3 – Derivative instruments and Hedging Activities for further details on swap contract activity.
 
Market and Counterparty Credit Risk
In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities. Futures contracts, when applicable, expose a Fund to minimal counterparty credit risk as they are exchange traded and the exchange’s clearinghouse, which is counterparty to all exchange traded futures, guarantees the futures contracts against default.
 
Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, 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 valuations fluctuate, either up or down, by at least the predetermined threshold amount.
 
Zero Coupon Securities
Each Fund is authorized to invest in zero coupon securities. A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Tax-exempt income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.
 
Repurchase Agreements
In connection with transactions in repurchase agreements, it is each Fund’s policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the counterparty defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited.
 
Organization Expenses and Offering Costs
The Adviser has agreed to reimburse all organization expenses ($11,000 for each Fund) and pay all offering costs (other than the sales load) that exceed $.04 per share for each Fund. The Funds’ share of offering costs ($1,054,500 and $288,000, for Build America Bond (NBB) and Build America Bond Opportunity (NBD), respectively) were recorded as a reduction of the proceeds from the sale of shares.

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 net credits earned on each Fund’s cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank.
 
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. GAAP 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.
 
2. Fair Value Measurements
Fair value is defined as the price that the Funds would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad levels listed below:
 
Level 1 – Quoted prices in active markets for identical securities.
Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3 – Significant unobservable inputs (including management’s assumptions in determining the fair value of investments).
 
The inputs or methodologies used for valuing securities are not an indication of the risk associated with investing in those securities. The following is a summary of each Fund’s fair value measurements as of March 31, 2011:

During the period from each Fund’s commencement of operations through March 31, 2011, the Funds recognized no significant transfers to/from Level 1, Level 2 or Level 3.
 
3. Derivative Instruments and Hedging Activities
The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes. For additional information on the derivative instruments in which each Fund was invested during and at the end of the reporting period, refer to the Portfolios of Investments, Financial Statements and Footnote 1 – General Information and Significant Accounting Policies.

6. 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 timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds.
 
At March 31, 2011, the cost and unrealized appreciation (depreciation) of investments (excluding investments in derivatives), as determined on a federal income tax basis, were as follows:

7. Management Fees and Other Transactions with Affiliates
Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within the Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within their Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.
 
   
The annual fund-level fee for each Fund, payable monthly, is calculated according to the following schedule: 
 
   
Average Daily Managed Assets*
Fund-Level Fee Rate
For the first $125 million 
.4500% 
For the next $125 million

For the next $500 million

For the next $1 billion

* For the fund-level and complex-level fees, managed assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen funds or assets in excess of $2 billion added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011. As of March 31, 2011, the complex-level fee rate for these Funds was .1800%.

Notes to
Financial Statements (continued)
 
The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser has entered into Sub-Advisory Agreements with the Sub-Adviser under which the Sub-Adviser manages the investment portfolios of the Funds. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser.
 
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.
 
8. Borrowing Arrangements
As part of its investment strategies, Build America Bond (NBB) uses borrowings to employ leverage. On May 26, 2010, the Fund entered into a $125 million (maximum commitment amount) committed 364-day secured line of credit (“Committed Secured Line”) with its custodian bank. Interest charged on the borrowed amount of the Committed Secured Line is calculated at a rate per annum equal to the higher of the overnight Federal Funds rate or the overnight London Inter-bank Offered Rate (LIBOR) plus 1.00%. In addition, the Fund accrues a commitment fee of .15% per annum on the maximum commitment amount, and paid a .15% one-time closing fee on the maximum commitment amount of the Committed Secured Line which was expensed during the current reporting period.
 
On June 2, 2010, Build America Bond (NBB) began to draw on the Committed Secured Line. As of March 31, 2011, the Fund’s outstanding balance on the Committed Secured Line was $44,000,000, which is recognized as “Borrowings” on the Statement of Assets and Liabilities. Interest expense and commitment and closing fees incurred on the Committed Secured Line are recognized as a component of “Interest expense” on the Statement of Operations.
 
During the period from June 2, 2010 through March 31, 2011, the Fund’s average daily balance outstanding and average annualized interest rate on the Committed Secured Line were $73,445,446 and 1.24%, respectively.
 
During May 2011, the Fund entered into a new $125 million committed 364-day secured line of credit. Interest charged on this facility will be calculated based on LIBOR plus .80%. The Fund will pay a one-time closing fee of .10% on the maximum commitment amount and will accrue a commitment fee of .15% on the maximum commitment amount.
 
9. New Accounting Pronouncement
Financial Accounting Standards Board (“FASB”) Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements.
 
On April 15, 2011, the FASB issued Accounting Standards Update No. 2011-03, (the “ASU”). The guidance in the ASU is intended to improve the accounting for repurchase and other similar agreements. Specifically, the ASU modifies the criteria for determining when these agreements would be accounted for as financing transactions (secured borrowings/lending agreements) as opposed to sale (purchase) transactions with commitments to repurchase (resell). At this time, management is evaluating the implications of this guidance and the impact it will have to the financial statement amounts or footnote disclosures, if any.

Annual Investment Management
Agreement Approval Process (Unaudited)
 
The Boards of Trustees (each, a “Board,” and each Trustee, a “Board Member”) of the Nuveen Build America Bond Fund (the “Build America Bond Fund”) and the Nuveen Build America Bond Opportunity Fund (the “Build America Bond Opportunity Fund” and, together with the Build America Bond Fund, the “Funds”) are responsible for approving advisory arrangements for the respective Fund. At a meeting held on February 26-28, 2010 (the “February Meeting”), the Board of the Build America Bond Fund was asked to approve the advisory arrangement for that Fund and, at a meeting held on September 15, 2010 (the “September Meeting”; the February Meeting and the September Meeting are each a “Meeting”), the Board of the Build America Bond Opportunity Fund was asked to approve the advisory arrangement for that Fund. At the respective Meeting, the Board Members, including the Board Members who are not parties to the advisory agreement or “interested persons” of any such parties (the “Independent Board Members”), considered and approved the investment management agreement (each, an “Advisory Agreement”) between the respective Fund and Nuveen Asset Management (the “Adviser”).
 
To assist the Board in its evaluation of the applicable Advisory Agreement at the respective Meeting, the Independent Board Members had received, in adequate time in advance of the Meeting or at prior meetings, materials which outlined, among other things:
 
·  
the nature, extent and quality of services expected to be provided by the Adviser;
 
·  
the organization of the Adviser, including the responsibilities of various depart- ments and key personnel;
 
·  
the expertise and background of the Adviser with respect to the Fund’s invest- ment strategy;
 
·  
the profitability of Nuveen Investments, Inc. (“Nuveen”) (which incorporated Nuveen’s wholly-owned affiliated sub-advisers);
 
·  
the proposed management fees of the Adviser, including comparisons of such fees with the management fees of comparable funds;
 
·  
the expected expenses of the Fund, including comparisons of the Fund’s expected expense ratio with the expense ratios of comparable funds; and
 
·  
the soft dollar practices of the Adviser, if any.
 
 
 
46 Nuveen Investments
 
 
 

 
 

 
At each Meeting, the Adviser made a presentation to and responded to questions from the Board. During each Meeting, the Independent Board Members also met privately with their legal counsel to review the Board’s duties under the Investment Company Act of 1940 (the “1940 Act”), the general principles of state law in reviewing and approving advisory contracts, the standards used by courts in determining whether investment company boards of directors have fulfilled their duties, factors to be considered in voting on advisory contracts and an adviser’s fiduciary duty with respect to advisory agreements and compensation. It is with this background that the Independent Board Members considered the Advisory Agreements. As outlined in more detail below (set forth in Section I for the Build America Bond Fund and in Section II for the Build America Bond Opportunity Fund), the Independent Board Members considered all factors they believed relevant with respect to the respective Fund including the following: (a) the nature, extent and quality of the services to be provided by the Adviser; (b) investment performance, as described below; (c) the profitability of Nuveen and its affiliates; (d) the extent to which economies of scale would be realized; and (e) whether fee levels reflect these economies of scale for the benefit of Fund investors.
 
I. NUVEEN BUILD AMERICA BOND FUND
 
A. Nature, Extent and Quality of Services
 
With respect to the Build America Bond Fund (for purposes of this Section I, such Fund is the “Fund” and the Advisory Agreement for such Fund is the “Advisory Agreement”), the Independent Board Members considered the nature, extent and quality of the Adviser’s services, including advisory services and administrative services. As the Adviser already serves as adviser to other Nuveen funds overseen by the Board Members, the Board has a good understanding of the Adviser’s organization, operations and personnel. As the Independent Board Members meet regularly throughout the year to oversee the Nuveen funds, including funds currently advised by the Adviser, the Independent Board Members have relied upon their knowledge from their meetings and any other interactions throughout the year of the Adviser and its services in evaluating the Advisory Agreement.
 
At the February Meeting and at prior meetings, the Independent Board Members reviewed materials outlining, among other things, the Adviser’s organization and business; the types of services that the Adviser or its affiliates provide to the Nuveen funds and are expected to provide to the Fund; and the experience of the Adviser with applicable investment strategies. Further, the Independent Board Members have evaluated the background, experience and track record of the Adviser’s investment personnel.
 
In addition to advisory services, the Independent Board Members considered the quality of any administrative or non-advisory services to be provided. In this regard, the Adviser is expected to provide the Fund with such administrative and other services (exclusive of, and in addition to, any such services provided by others for the Fund) and officers and other personnel as are necessary for the operations of the Fund. In addition to investment management services, the Adviser and its affiliates will provide the Fund with
 
 
 
Nuveen Investments 47
 
 
 

 
 

 
Annual Investment Management Agreement
Approval Process (Unaudited) (continued)
 
a wide range of services, including, among other things, product management, fund administration, oversight of service providers, shareholder services, administration of Board relations, regulatory and portfolio compliance and legal support.
 
In addition to the foregoing services, the Independent Board Members also noted the additional services that the Adviser or its affiliates provide to closed-end funds, including, in particular, Nuveen’s continued commitment to supporting the secondary market for the common shares of its closed-end funds through a variety of programs designed to raise investor and analyst awareness and understanding of closed-end funds. These efforts include maintaining an investor relations program to provide timely information and education to financial advisers and investors; providing advertising and marketing for the closed-end funds; maintaining websites; and providing educational seminars.
 
Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services expected to be provided to the Fund under the Advisory Agreement were satisfactory.
 
B. Investment Performance
 
At the time of the February Meeting, the Fund was new and therefore did not have its own performance history. However, the Independent Board Members were familiar with the Adviser’s performance record on other Nuveen funds.
 
C. Fees, Expenses and Profitability
1. Fees and Expenses
In evaluating the management fees and expenses that the Fund was expected to bear, the Independent Board Members considered, among other things, the Fund’s proposed management fee structure and its expected expense ratios in absolute terms as well as compared with the fees and expense ratios of comparable funds. In this regard, the Board reviewed, among other things, the management fees of leveraged municipal closed-end funds given that the Fund’s portfolio was expected to be similar in many respects to that of a tax-exempt bond fund. In addition, the Board reviewed the management fees of various general taxable bond funds.
 
In addition, the Independent Board Members noted that the Fund may make investments in certain instruments that have the economic effect of leverage, including inverse floating rate securities. The Independent Board Members recognized that assets attributable to the Fund’s use of effective leverage would be included in the amount of assets upon which the advisory fee is calculated. In this regard, the Independent Board Members noted that the advisory fee is based on a percentage of average daily “Managed Assets.” “Managed Assets” generally means the total assets of the Fund minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating effective leverage). “Total assets” for this purpose includes assets attributable to the Fund’s use of effective leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to,
 
 
 
48 Nuveen Investments
 
 
 

 
 

 
the portion of assets in special purpose trusts of which the Fund owns the inverse floater certificates that has been effectively financed by the trust’s issuance of floating rate certificates. The Board Members recognized that because a decision to increase the Fund’s leverage would have the effect, all other things being equal, of increasing Managed Assets, and, therefore, the Adviser’s management fee, the Adviser may have an incentive to increase the Fund’s use of leverage. Notwithstanding the foregoing, the Independent Board Members considered that the Adviser would seek to manage that incentive by only increasing the Fund’s use of leverage when it determines that such increase is consistent with the Fund’s investment objectives, and by periodically reviewing the Fund’s performance and use of leverage with the Board.
 
The Independent Board Members also considered the fund-level breakpoint schedule and the complex-wide breakpoint schedule (described in further detail below) and any applicable fee waivers and expense reimbursements expected to be provided. Based on their review of the fee and expense information provided, the Independent Board Members determined that the Fund’s management fees were reasonable in light of the nature, extent and quality of services to be provided to the Fund.
 
2. Comparisons with the Fees of Other Clients
Due to their experience with other Nuveen funds, the Board Members were familiar with the fees the Adviser assesses to other clients. Such other clients include separately managed accounts (both retail and institutional accounts) and funds that are not offered by Nuveen but are sub-advised by one of Nuveen’s investment management teams. In evaluating the comparisons of fees, the Independent Board Members have noted, at the February Meeting or at prior meetings, that the fee rates charged to a fund (such as the Fund) and charged to other clients vary, among other things, because of the different services involved and the additional regulatory and compliance requirements associated with registered investment companies, such as the Fund. Accordingly, the Independent Board Members have considered the differences in the product types, including, but not limited to, the services to be provided, the structure and operations, product distribution and costs thereof, portfolio investment policies, investor profiles, account sizes and regulatory requirements. The Independent Board Members have noted, in particular, that the range of services as described above to be provided to a fund (such as the Fund) is much more extensive than that provided to separately managed accounts. Given the inherent differences in the products, particularly the extensive services to be provided to the Fund, the Independent Board Members believe such facts justify the different levels of fees.
 
3. Profitability of Nuveen
In conjunction with its review of fees at prior meetings, the Independent Board Members have considered the profitability of Nuveen for its advisory activities (which incorporated Nuveen’s wholly-owned affiliated sub-advisers) and its financial
 
 
 
Nuveen Investments 49
 
 
 

 
 

 
Annual Investment Management Agreement
Approval Process (Unaudited) (continued)
 
condition. At the February Meeting or prior meetings, the Independent Board Members reviewed the revenues and expenses of Nuveen’s advisory activities, the allocation methodology used in preparing the profitability data and an analysis of the key drivers behind the changes in revenues and expenses that impacted profitability. They also reviewed the Form 8-K filed by Nuveen on January 12, 2010 and the Form 10-Q filed by Nuveen on November 12, 2009 (for the period ending September 30, 2009). The Independent Board Members have also considered, at the February Meeting or at prior meetings, Nuveen’s revenues for advisory activities, expenses, and profit margin compared to that of various unaffiliated management firms with similar amounts of assets under management and relatively comparable asset composition prepared by Nuveen.
 
In reviewing profitability, the Independent Board Members have recognized the subjective nature of determining profitability, which may be affected by numerous factors, including the allocation of expenses. Further, the Independent Board Members have recognized the difficulties in making comparisons as the profitability of other advisers generally is not publicly available and the profitability information that is available for certain advisers or management firms may not be representative of the industry and may be affected by, among other things, the adviser’s particular business mix, capital costs, types of funds managed and expense allocations. Notwithstanding the foregoing, the Independent Board Members reviewed Nuveen’s methodology and assumptions for allocating expenses across product lines to determine profitability. In reviewing profitability, the Independent Board Members recognized Nuveen’s investment in its fund business. Based on their review, the Independent Board Members concluded that Nuveen’s level of profitability for its advisory activities was reasonable in light of the services to be provided.
 
In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other amounts expected to be paid to the Adviser as well as any indirect benefits (such as soft dollar arrangements, if any) the Adviser and its affiliates are expected to receive that are directly attributable to their management of the Fund, if any. See Section E below for additional information on indirect benefits the Adviser may receive as a result of its relationship with the Fund. Based on their review of the overall fee arrangements of the Fund, the Independent Board Members determined that the advisory fees and expected expenses of the Fund were reasonable.
 
D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale
 
With respect to economies of scale, the Independent Board Members have recognized the potential benefits resulting from the costs of a fund being spread over a larger asset base, although economies of scale are difficult to measure and predict with precision, particularly on a fund-by-fund basis. The Independent Board Members therefore considered whether the Fund could be expected to benefit from any economies of scale. One

method to help ensure that shareholders share in these benefits is to include breakpoints in the advisory fee schedule. Generally, management fees for funds in the Nuveen complex are comprised of a fund-level component and a complex-level component. Accordingly, the Independent Board Members received and reviewed the schedule of proposed advisory fees for the Fund, including fund-level breakpoints thereto. In this regard, however, given that the Fund is a closed-end fund, the Independent Board Members recognized that although the Fund may from time to time make additional share offerings, the growth in its assets will occur primarily through appreciation of its investment portfolio.
 
In addition to fund-level advisory fee breakpoints, the Board also considered the Fund’s complex-wide fee arrangement. Pursuant to the complex-wide fee arrangement, the fees of the funds in the Nuveen complex, including the Fund, are generally reduced as the assets in the fund complex reach certain levels. In evaluating the complex-wide fee arrangement, the Independent Board Members have considered that the complex-wide fee arrangement seeks to provide the benefits of economies of scale to fund shareholders when total fund complex assets increase, even if assets of a particular fund are unchanged or have decreased. The approach reflects the notion that some of Nuveen’s costs are attributable to services provided to all its funds in the complex and therefore all funds benefit if these costs are spread over a larger asset base. Based on their review, the Independent Board Members concluded that the breakpoint schedules and complex-wide fee arrangement were acceptable and reflect economies of scale to be shared with the Fund’s shareholders.
 
E. Indirect Benefits
 
In evaluating fees, the Independent Board Members also considered information regarding potential “fall out” or ancillary benefits that the Adviser or its affiliates may receive as a result of its relationship with the Fund. In this regard, the Independent Board Members considered any revenues received by affiliates of the Adviser for serving as agent at Nuveen’s trading desk.
 
In addition to the above, the Independent Board Members considered whether the Adviser will receive any benefits from soft dollar arrangements whereby a portion of the commissions paid by the Fund for brokerage may be used to acquire research that may be useful to the Adviser in managing the assets of the Fund and other clients. The Independent Board Members noted that the Adviser does not currently have any soft dollar arrangements; however, to the extent certain bona fide agency transactions that occur on markets that traditionally trade on a principal basis and riskless principal transactions are considered as generating “commissions,” the Adviser intends to comply with the applicable safe harbor provisions.
 
Based on their review, the Independent Board Members concluded that any indirect benefits received by the Adviser as a result of its relationship with the Fund were reasonable and within acceptable parameters.

F. Approval
 
The Independent Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including a majority of the Independent Board Members, concluded that the terms of the Advisory Agreement were fair and reasonable, that the Adviser’s fees are reasonable in light of the services to be provided to the Fund and that the Advisory Agreement should be and was approved on behalf of the Fund.
 
II. NUVEEN BUILD AMERICA BOND OPPORTUNITY FUND
 
A. Nature, Extent and Quality of Services
 
With respect to the Build America Bond Opportunity Fund (for purposes of this Section II, such Fund is the “Fund” and the Advisory Agreement for such Fund is the “Advisory Agreement”), the Independent Board Members considered the nature, extent and quality of the Adviser’s services, including advisory services and administrative services. As the Adviser already serves as adviser to other Nuveen funds overseen by the Board Members, the Board has a good understanding of the Adviser’s organization, operations and personnel. As the Independent Board Members meet regularly throughout the year to oversee the Nuveen funds, including funds currently advised by the Adviser, the Independent Board Members have relied upon their knowledge from their meetings and any other interactions throughout the year of the Adviser and its services in evaluating the Advisory Agreement.
 
At the September Meeting and at prior meetings, the Independent Board Members reviewed materials outlining, among other things, the Adviser’s organization and business; the types of services that the Adviser or its affiliates provide to the Nuveen funds and are expected to provide to the Fund; and the experience of the Adviser with applicable investment strategies. Further, the Independent Board Members have evaluated the background, experience and track record of the Adviser’s investment personnel.
 
In addition to advisory services, the Independent Board Members considered the quality of any administrative or non-advisory services to be provided. In this regard, the Adviser is expected to provide the Fund with such administrative and other services (exclusive of, and in addition to, any such services provided by others for the Fund) and officers and other personnel as are necessary for the operations of the Fund. In addition to investment management services, the Adviser and its affiliates will provide the Fund with a wide range of services, including, among other things, product management, fund administration, oversight of service providers, shareholder services, administration of Board relations, regulatory and portfolio compliance and legal support.
 
In addition to the foregoing services, the Independent Board Members also noted the additional services that the Adviser or its affiliates provide to closed-end funds, including, in particular, Nuveen’s continued commitment to supporting the secondary market for the common shares of its closed-end funds through a variety of programs designed to raise investor and analyst awareness and understanding of closed-end funds. These
 
 
52 Nuveen Investments
 
 
 

 
 

 
efforts include maintaining an investor relations program to provide timely information and education to financial advisers and investors; providing advertising and marketing for the closed-end funds; maintaining websites; and providing educational seminars.
 
Based on their review, the Independent Board Members found that, overall, the nature, extent and quality of services expected to be provided to the Fund under the Advisory Agreement were satisfactory.
 
B. Investment Performance
 
At the time of the September Meeting, the Fund was new and therefore did not have its own performance history. The Independent Board Members, however, were familiar with the Adviser’s performance record on other Nuveen funds. Although the Adviser acts as adviser to another similar fund (the Build America Bond Fund), such fund had been trading for less than six months and, therefore, did not have an extensive performance history.
 
C. Fees, Expenses and Profitability
1. Fees and Expenses
In evaluating the management fees and expenses that the Fund was expected to bear, the Independent Board Members considered, among other things, the Fund’s proposed management fee structure and its expected expense ratios in absolute terms as well as compared with the fees and expense ratios of comparable funds. In this regard, the Board reviewed the management fees of various general taxable bond funds, recognizing that the Build America Bond Fund (which, as indicated above, is similar to the Fund) is classified in that category. The Board noted the Adviser’s proposal that the management fees for the Fund be the same as the fee schedule which applies to the Build America Bond Fund and Nuveen’s tax-exempt leveraged municipal closed-end funds.
 
In addition, the Independent Board Members noted that the Fund may make investments in certain instruments that have the economic effect of leverage, including, but not limited to, investments in inverse floating rate securities. The Independent Board Members recognized that assets attributable to the Fund’s use of financial leverage would be included in the amount of assets upon which the advisory fee is calculated. In this regard, the Independent Board Members noted that the advisory fee is based on the sum of a fund-level fee and a complex-level fee. The fund-level fee portion is based on a percentage of the Fund’s average daily “Managed Assets.” For the Fund, “Managed Assets” generally means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating financial leverage). “Total assets” for this purpose includes assets attributable to the Fund’s use of financial leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), such as, but not limited to, the portion of assets in tender option bond trusts of which the Fund owns the residual interest certificates
 
Nuveen Investments 53
 
 
 

 
 

 
Annual Investment Management Agreement
Approval Process (Unaudited) (continued)
 
that have been effectively financed by the trust’s issuance of floating rate certificates. The complex-level fee is based on the managed assets of certain funds in the Nuveen complex which generally includes assets attributable to any preferred shares that may be outstanding and any borrowings (including the issuance of commercial paper or notes) for purposes of financial leverage. The Board Members recognized that because a decision to increase the Fund’s leverage would have the effect, all other things being equal, of increasing Managed Assets, and, therefore, the Adviser’s management fee, the Adviser may have an incentive to increase the Fund’s use of leverage. Notwithstanding the foregoing, the Independent Board Members considered that the Adviser would seek to manage that incentive by only increasing the Fund’s use of leverage when it determines that such increase is consistent with the Fund’s investment objectives, and by periodically reviewing the Fund’s performance and use of leverage with the Board.
 
The Independent Board Members also considered the fund-level breakpoint schedule and the complex-wide breakpoint schedule (described in further detail below) and any applicable fee waivers and expense reimbursements expected to be provided. Based on their review of the fee and expense information provided, the Independent Board Members determined that the Fund’s management fees were reasonable in light of the nature, extent and quality of services to be provided to the Fund.
 
2. Comparisons with the Fees of Other Clients
 
Due to their experience with other Nuveen funds, the Board Members were familiar with the fees the Adviser assesses to other clients. Such other clients include separately managed accounts (both retail and institutional accounts) and funds that are not offered by Nuveen but are sub-advised by one of Nuveen’s investment management teams. In evaluating the comparisons of fees, the Independent Board Members have noted, at the September Meeting or at prior meetings, that the fee rates charged to a fund (such as the Fund) and charged to other clients vary, among other things, because of the different services involved and the additional regulatory and compliance requirements associated with registered investment companies, such as the Fund. Accordingly, the Independent Board Members have considered the differences in the product types, including, but not limited to, the services to be provided, the structure and operations, product distribution and costs thereof, portfolio investment policies, investor profiles, account sizes and regulatory requirements. The Independent Board Members have noted, in particular, that the range of services as described above to be provided to a fund (such as the Fund) is much more extensive than that provided to separately managed accounts. Given the inherent differences in the products, particularly the extensive services to be provided to the Fund, the Independent Board Members believe such facts justify the different levels of fees.

3. Profitability of Nuveen
 
In conjunction with its review of fees at prior meetings, the Independent Board Members have considered the profitability of Nuveen for its advisory activities (which incorporated Nuveen’s wholly-owned affiliated sub-advisers) and its financial condition. At the September Meeting or prior meetings, the Independent Board Members reviewed the revenues and expenses of Nuveen’s advisory activities, the allocation methodology used in preparing the profitability data and an analysis of the key drivers behind the changes in revenues and expenses that impacted profitability. In addition, they reviewed the Form 8-K filed by Nuveen on August 13, 2010 and the Form 10-K filed by Nuveen on March 31, 2010 (for the period ending December 31, 2009). The Independent Board Members have also considered, at the September Meeting or at prior meetings, Nuveen’s revenues for advisory activities, expenses, and profit margin compared to that of various unaffiliated management firms with similar amounts of assets under management and relatively comparable asset composition prepared by Nuveen.
 
In reviewing profitability, the Independent Board Members have recognized the subjective nature of determining profitability, which may be affected by numerous factors, including the allocation of expenses. Further, the Independent Board Members have recognized the difficulties in making comparisons as the profitability of other advisers generally is not publicly available and the profitability information that is available for certain advisers or management firms may not be representative of the industry and may be affected by, among other things, the adviser’s particular business mix, capital costs, types of funds managed and expense allocations. Notwithstanding the foregoing, the Independent Board Members reviewed Nuveen’s methodology and assumptions for allocating expenses across product lines to determine profitability. In reviewing profitability, the Independent Board Members recognized Nuveen’s investment in its fund business. Based on their review, the Independent Board Members concluded that Nuveen’s level of profitability for its advisory activities was reasonable in light of the services to be provided.
 
In evaluating the reasonableness of the compensation, the Independent Board Members also considered any other amounts expected to be paid to the Adviser as well as any indirect benefits (such as soft dollar arrangements, if any) the Adviser and its affiliates are expected to receive that are directly attributable to their management of the Fund, if any. See Section E below for additional information on indirect benefits the Adviser may receive as a result of its relationship with the Fund. Based on their review of the overall fee arrangements of the Fund, the Independent Board Members determined that the advisory fees and expected expenses of the Fund were reasonable.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale
 
With respect to economies of scale, the Independent Board Members have recognized the potential benefits resulting from the costs of a fund being spread over a larger asset base, although economies of scale are difficult to measure and predict with precision, particularly on a fund-by-fund basis. The Independent Board Members therefore considered whether the Fund could be expected to benefit from any economies of scale. One method to help ensure that shareholders share in these benefits is to include breakpoints in the advisory fee schedule. Generally, management fees for funds in the Nuveen complex are comprised of a fund-level component and a complex-level component. Accordingly, the Independent Board Members received and reviewed the schedule of proposed advisory fees for the Fund, including fund-level breakpoints thereto. In this regard, however, given that the Fund is a closed-end fund, the Independent Board Members recognized that although the Fund may from time to time make additional share offerings, the growth in its assets will occur primarily through appreciation of its investment portfolio.
 
In addition to fund-level advisory fee breakpoints, the Board also considered the Fund’s complex-wide fee arrangement. Pursuant to the complex-wide fee arrangement, the fees of the funds in the Nuveen complex, including the Fund, are generally reduced as the assets in the fund complex reach certain levels. In evaluating the complex-wide fee arrangement, the Independent Board Members have considered that the complex-wide fee arrangement seeks to provide the benefits of economies of scale to fund shareholders when total fund complex assets increase, even if assets of a particular fund are unchanged or have decreased. The approach reflects the notion that some of Nuveen’s costs are attributable to services provided to all its funds in the complex and therefore all funds benefit if these costs are spread over a larger asset base. Based on their review, the Independent Board Members concluded that the breakpoint schedules and complex-wide fee arrangement were acceptable and reflect economies of scale to be shared with the Fund’s shareholders.
 
E. Indirect Benefits
 
In evaluating fees, the Independent Board Members also considered information regarding potential “fall out” or ancillary benefits that the Adviser or its affiliates may receive as a result of its relationship with the Fund. In this regard, the Independent Board Members considered any revenues received by affiliates of the Adviser for serving as agent at Nuveen’s trading desk.
 
In addition to the above, the Independent Board Members considered whether the Adviser will receive any benefits from soft dollar arrangements whereby a portion of the commissions paid by the Fund for brokerage may be used to acquire research that may be useful to the Adviser in managing the assets of the Fund and other clients. The Independent Board Members noted that the Adviser does not currently have any soft dollar arrangements; however, to the extent certain bona fide agency transactions that

occur on markets that traditionally trade on a principal basis and riskless principal transactions are considered as generating “commissions,” the Adviser intends to comply with the applicable safe harbor provisions.
 
Based on their review, the Independent Board Members concluded that any indirect benefits received by the Adviser as a result of its relationship with the Fund were reasonable and within acceptable parameters.
 
F. Approval
 
The Independent Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members, including a majority of the Independent Board Members, concluded that the terms of the Advisory Agreement were fair and reasonable, that the Adviser’s fees are reasonable in light of the services to be provided to the Fund and that the Advisory Agreement should be and was approved on behalf of the Fund.

Board Approval of Sub-Advisory
Arrangements (Unaudited)
 
Since the Meetings, Nuveen has engaged in an internal restructuring (the “Restructuring”) pursuant to which the portfolio management services provided by the Adviser to the Funds were transferred to Nuveen Asset Management, LLC (“NAM LLC”), a newly-organized wholly-owned subsidiary of the Adviser and the Adviser changed its name to Nuveen Fund Advisors, Inc. (“NFA”). The Adviser, under its new name NFA, continues to serve as investment adviser to the Funds and, in that capacity, will continue to provide various oversight, administrative, compliance and other services. To effectuate the foregoing, NFA entered into sub-advisory agreements with NAM LLC on behalf of the Funds (each, a “Sub-Advisory Agreement”). Under each Sub-Advisory Agreement, NAM LLC, subject to the oversight of NFA and the Board, will furnish an investment program, make investment decisions for, and place all orders for the purchase and sale of securities for the portion of the respective Fund’s investment portfolio allocated to it by NFA. There have been no changes to the advisory fees paid by the Funds; rather, NFA will pay a portion of the investment advisory fee it receives to NAM LLC for its sub-advisory services. The Independent Board Members reviewed the allocation of fees between NFA and NAM LLC. NFA and NAM LLC do not anticipate any reduction in the nature or level of services provided to the Funds following the Restructuring. The personnel of NFA who engaged in portfolio management activities prior to the spinoff of NAM LLC are not expected to materially change as a result of the spinoff. In light of the foregoing, at a meeting held on November 16-18, 2010, the Board Members, including a majority of the Independent Board Members, approved the Sub-Advisory Agreements on behalf of the Funds. Given that the Restructuring was not expected to reduce the level or nature of services provided and the advisory fees paid by the Funds were the same, the factors considered and determinations made at the applicable Meeting in approving the respective Advisory Agreements were equally applicable to the approval of the Sub-Advisory Agreements.

Reinvest Automatically,
Easily and Conveniently
 
Nuveen makes reinvesting easy. A phone call is all it takes to set up your reinvestment account.
 
Nuveen Closed-End Funds Automatic Reinvestment Plan
 
Your Nuveen Closed-End Fund allows you to conveniently reinvest 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 compounding. Just like distributions in cash, there may be times when income or capital gains taxes may be payable on 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 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. Distributions received to purchase shares in the open market will normally be invested shortly after the distribution payment date. No interest will be paid on distributions awaiting reinvestment. Because the market price of the shares may increase before purchases are completed, the average purchase price per share may
 
 
 
 
Nuveen Investments 59
 
 
 

 
 

 
Reinvest Automatically,
Easily and Conveniently (continued)
 
 
exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the 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.
 
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
 
  
Auction Rate Bond: An auction rate bond is a security whose interest payments are adjusted periodically through an auction process, which process typically also serves as a means for buying and selling the bond. Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have “failed,” with current holders receiving a formula-based interest rate until the next scheduled auction.
 
  
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 invest- ment’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 market-value-weighted average of the effective maturity dates of the individual securities including cash. In the case of a bond that has been advance-refunded to a call date, the effective maturity is the date on which the bond is scheduled to be redeemed using the proceeds of an escrow account. In most other cases the effective maturity is the stated maturity date of the security.
 
  
Effective Leverage: Effective leverage is a Fund’s effective economic leverage, and includes both structural leverage and the leverage effects of certain derivative invest- ments in the Fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any structural leverage.
 
  
Inverse Floaters: Inverse floating rate securities, also known as inverse floaters, 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 typi- cally 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: Using borrowed money to invest in securities or other assets.

Glossary of Terms
Used in this Report (continued)
 
  
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 NAV per common share is calculated by subtracting the liabilities of the Fund from its total assets and then dividing the remainder by the number of common shares outstanding. Fund NAVs are calculated at the end of each business day.
 
  
Pre-Refunding: Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value.
 
  
Structural Leverage: Structural Leverage consists of preferred shares or debt issued by the fund. Both of these are part of a fund’s capital structure. Structural leverage is sometimes referred to as “’40 Act Leverage” and is subject to asset coverage limits set in the Investment Company Act of 1940.
 
  
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.
 
  
Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Tax-exempt income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Nuveen Build America Bond Fund

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).

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.

Nuveen Fund Advisors, Inc. is the registrant's investment adviser (also referred to as the "Adviser").  The Adviser is responsible for the selection and on-going monitoring of the Fund's investment portfolio, managing the Fund's business affairs and providing certain clerical, bookkeeping and administrative services.  The Adviser has engaged Nuveen Asset Management, LLC (“NAM” or “Sub-Adviser”) as Sub-Adviser to provide discretionary investment advisory services. The following section provides information on the portfolio managers at the Sub-Adviser:

Assets are as of March 31, 2011.  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 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 NAM). 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 December 31, 2010, the S&P/Investortools Municipal Bond index was comprised of 57,308 securities with an aggregate current market value of $1,226 billion.

Base salary. Each portfolio manager is paid a base salary that is set at a level determined by NAM in accordance with its overall compensation strategy discussed above. NAM 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 NAM’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 NAM’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.    In connection with the acquisition of Nuveen Investments, Inc., by a group of investors lead by Madison Dearborn Partners in November 2007, certain employees, including portfolio managers, received profit interests in Nuveen’s parent.  These profit interests entitle the holders to participate in the appreciation  in the value of Nuveen beyond the issue date and vest over five to seven years, or earlier in the case of a liquidity event.  In addition, in July 2009, Nuveen Investments created and funded a trust, as part of a newly-established incentive program, which purchased shares of certain Nuveen Mutual Funds and awarded such shares, subject to vesting, to certain employees, including portfolio managers.

Material Conflicts of Interest. Each portfolio manager’s simultaneous management of the registrant 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 Registrant and the other account. NAM, however, believes that such potential conflicts are mitigated by the fact that the NAM 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, NAM has adopted a Code of Conduct that sets forth policies regarding conflicts of interest.

Beneficial Ownership of Securities. As of the March 31, 2011, 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.
