Portfolio Managers’

Comments

Nushares Short-Term REIT ETF (NURE)

This Fund features portfolio management by Teachers Advisors, LLC, an affiliate of Nuveen Fund Advisors, LLC. Portfolio managers Philip James (Jim) Campagna, CFA, and Lei Liao, CFA, discuss U.S. economic and market conditions, key investment strategies and the twelve-month performance of NURE. Jim and Lei have managed NURE since its commencement of operations on December 19, 2016.

What factors affected the U.S. economy and the real estate investment trust (REIT) market during the twelve-month reporting period ended December 31, 2017?

The U.S. economy began the year at a sluggish pace but gained momentum mid-year, growing at an annualized rate above 3% in the second and third quarters of 2017. In the final three months of 2017, the economy slowed slightly to 2.6%, as reported by the Bureau of Economic Analysis “advance” estimate of fourth-quarter gross domestic product (GDP). GDP is the value of goods and services produced by the nation’s economy less the value of the goods and services used up in production, adjusted for price changes.

Although the hurricanes temporarily weakened shopping and dining out activity, consumer spending remained the main driver of demand in the economy, as consumers benefited from employment and wage gains. Business investment, which had been lackluster in the recovery so far, accelerated in 2017, and hiring continued to boost employment. As reported by the Bureau of Labor Statistics, the unemployment rate fell to 4.1% in December 2017 from 4.7% in December 2016 and job gains averaged around 171,000 per month for the past twelve months. Higher energy prices, especially gasoline, helped drive a steady increase in inflation over this reporting period. The Consumer Price Index (CPI) increased 2.1% over the twelve-month reporting period ended December 31, 2017 on a seasonally adjusted basis, as reported by the Bureau of Labor Statistics. The core CPI (which excludes food and energy) increased 1.8% during the same period, slightly below the Federal Reserve’s (Fed) unofficial longer term inflation objective of 2.0%.

The housing market also continued to improve, with historically low mortgage rates and low inventory driving home prices higher. The S&P CoreLogic Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, recorded a 6.2% annual gain in November 2017 (most recent data available at the time this report was prepared). The 10-City and 20-City Composites reported year-over-year increases of 6.1% and 6.4, respectively.

With the U.S. economy delivering a sustainable growth rate and employment strengthening, the Fed’s policy making committee raised its main benchmark interest rate in December 2016, March 2017, June 2017 and December 2017. These moves were widely expected by the markets, as were the Fed’s decisions to leave rates unchanged at the July, September and October/November 2017 meetings. (There was no August meeting.) The Fed also announced it would begin reducing its balance sheet in October 2017 by allowing a small amount of maturing Treasury and mortgage securities to roll off without reinvestment. The market expects the pace to remain moderate and predictable, with minimal market disruption.

While the markets remained comfortable with the course of monetary policy during this reporting period, the political environment was frequently a source of uncertainty. Markets were initially highly optimistic about pricing in the new administration’s “pro-growth”

Portfolio Managers’ Comments (continued)

fiscal agenda after Donald Trump won the election. After stumbling with health care reform earlier in 2017, legislators passed a major tax overhaul at the end of December, which lowered individual and corporate tax rates. While the new tax law changes are expected to be stimulative to the economy, there are some concerns that it could pose challenges to the Fed’s ability to manage interest rates in the future. Although incoming Fed Chairman Jerome Powell is expected to maintain the course established by outgoing Chair Janet Yellen, after her term expired in February 2018, markets may deem this as another source of uncertainty.

Geopolitical risks were prominent, but some concerns eased by the end of the period. Rhetoric surrounding U.S. trade with China and the renegotiation of the North American Free Trade Agreement (NAFTA) was toned down. After an uncertain start, the “Brexit” talks between the U.K. and European Union progressed to the next phase. Closely watched elections in the Netherlands, France and Germany yielded market friendly results. Tensions between the U.S. and North Korea intensified but did not have a lasting impact on the markets.

Real estate investment trusts (REITs) delivered positive performance during the reporting period, although they lagged the stronger rallies of U.S. and global equities. Industrial REITs (which the Fund does not invest in) were among the top performing REIT subsectors, as investors sought exposure to the rapid growth trends of e-commerce and digital technology. Manufactured home REITs benefited from homebuyers seeking affordable housing amid tight supply. On the contrary, mall and shopping center REITs sold off sharply during the reporting period. As competition from online retailers intensified, retailer bankruptcies and brick-and-mortar store closings have increased, weighing heavily on the outlook and performance of mall and shopping center REITs.

What key strategies were used to manage the Fund during the twelve-month reporting period and how did these strategies influence performance?

The Fund employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the Dow Jones U.S. Select Short-Term REIT Index (the “Index”). The Index is a subset of the Dow Jones U.S. Select REIT Index (the “Base Index”), which generally includes equity REITs traded on a national securities exchange in the United States that derive at least 75% of their total revenue from the ownership and operation of real estate assets and that have a minimum total market capitalization of $200 million at the time of their inclusion. The Index selects REITs from the Base Index that are classified as concentrating their holdings in apartment buildings, hotels, self-storage facilities or manufactured home properties, as REITs investing in these sectors typically have shorter lease durations than REITs investing in other sectors. Index holdings are weighted by float-adjusted market capitalization, provided that no single REIT can comprise more than 5% of the Index as of any rebalance date. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded.

The Fund attempts to replicate the Index by investing all, or substantially all, of its assets in the REITs that make up the Index, holding each REIT in approximately the same proportion as its weighting in the Index. The Fund rebalances its holdings quarterly in response to the quarterly Index rebalances.

As of December 31, 2017, 45.7% of the Fund’s net assets were invested in apartment REITs, 28.6% in hotel REITs, 16.2% in self-storage REITs and 8.8% in manufactured home REITs.

How did the Fund perform during the twelve-month reporting period ended December 31, 2017?

The table in the Fund’s Performance Overview and Expense Ratios section of this report provides the Fund’s total return performance for the one-year and since inception periods ended December 31, 2017. The Fund’s total returns at net asset value (NAV) are compared with the performance of the Index, which the Fund is designed to track. The Fund’s total return underperformed the Dow Jones U.S. Select Short-Term REIT Index during the reporting period. The relative underperformance is mainly attributable to the transaction costs related to the Fund’s acquisition of structured securities, as well as fees and expenses incurred by the Fund that are not incurred by the Index. The Dow Jones U.S. Select Short-Term REIT Index is unmanaged and therefore its returns do not reflect any fees or expenses, which would detract from its performance. You cannot invest directly in an index.

During the twelve-month reporting period, manufactured homes REITs strongly outperformed the other three REIT sectors in which the Fund invests, lifted by favorable supply-demand dynamics. The hotels, apartments and self-storage sectors delivered moderate gains during the reporting period.

Risk Considerations

and Distribution Information

Nushares Short-Term REIT ETF (NURE)

Investing involves risk; principal loss is possible. There is no guarantee the Fund’s investment objectives will be achieved. This ETF seeks to generally track the investment results of an index; however the Fund may underperform, outperform or be more volatile than the referenced index. This Fund invests in equity REITs, which invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains from the sale of appreciated properties. Equity REITs can be greatly affected by economic downturns, by changes in real estate values, rents, property taxes, and interest rates, and by revisions to tax rules or other regulations applicable to REITs. The value of equity securities may decline significantly over short or extended periods of time. The Fund’s assets will generally be concentrated in the securities of issuers in the real estate industry, and, accordingly, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry. These and other risk considerations, such as interest rate, non-diversification, and smaller company risks, are described in detail in the Fund’s prospectus.

Dividend Information

Regular dividends are declared and distributed quarterly for Nushares Short-Term REIT ETF (NURE). The Fund intends to pay out substantially all of the distributions it receives from investments in real estate investment trust (REIT) securities, less expenses, each quarter. To permit the Fund to maintain a more stable dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net investment income it actually earned during the period. If the Fund has cumulatively earned more than it has paid in dividends, it will hold the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s NAV. Conversely, if the Fund has cumulatively paid out dividends more than it has earned, the excess will constitute negative UNII that will likewise be reflected in the Fund’s NAV. The Fund will, over time, pay all of its net investment income as dividends to shareholders.

In certain instances, a portion of the Fund’s distributions may be paid from sources or comprised of elements other than ordinary income, including capital gains and/or a return of capital. This is generally due to the fact that the tax character of Fund distributions for a fiscal year is dependent upon the amount and tax character of distributions received from securities held in the Fund’s portfolio. Distributions received from certain securities in which the Fund invests, most notably REIT securities, may be characterized for tax purposes as ordinary income, long-term capital gain and/or a return of capital. The issuer of a REIT security typically reports the tax character of its distributions only once per year, generally during the first two months of the following calendar year. The full amount of the distributions received from such securities is included in the Fund’s ordinary income during the course of the year until such time the Fund is notified by the issuer of the actual tax character. To the extent that at the time of a particular distribution the Fund estimates that a portion of that distribution is attributable to a source or sources other than ordinary income, the Fund would send shareholders a notice to that effect. The final determination of the sources and tax character of all distributions for the fiscal year is made after the end of the fiscal year.

The Fund seeks to pay regular dividends at a rate that reflects the cash flow received from the Fund’s investments in portfolio securities. Fund distributions are not intended to include expected portfolio appreciation; however, the Fund invests in securities that make payments which ultimately may be fully or partially characterized for tax purposes by the securities’ issuers as gains or return of capital. While the reported sources of distributions may include capital gains and/or return of capital for tax purposes, the Fund intends to distribute only the net cash flow received as opposed to a distribution rate based on long-term total return. This tax treatment will generally “flow through” to the Fund’s distributions, but the specific tax treatment is often not known with certainty until after the end of the Fund’s tax year. As a result, certain portions of the regular distributions by the Fund throughout the year were later re-characterized for tax purposes as either long-term gains (both realized and unrealized), or as a non-taxable return of capital, as set forth in the table below.

Risk Considerations and Dividend Information (continued)

Nushares Short-Term REIT ETF (NURE) – Data as of December 31, 2017

The amounts and sources of distributions reported in this notice are for financial reporting purposes and are not being provided for tax reporting purposes. The actual amounts and character of the distributions for tax reporting purposes will be reported to shareholders on Form 1099-DIV which will be sent to shareholders shortly after calendar year-end. More details about each Fund’s distributions and the basis for these estimates are available on www.nuveen.com.

The Tax Cuts and Jobs Act

A large portion of the Fund’s portfolio holdings consist of REITs. For tax years beginning after December 31, 2017, The Tax Cuts and Jobs Act generally would allow a non-corporate taxpayer a deduction of 20% of the investor’s domestic qualified business income received from certain pass-through entities, including REITs. However, Regulated Investment Companies (RICs) such as the Fund are not explicitly given the ability to pass the deduction through to their non-corporate shareholders. Treasury has been approached to provide RICs the ability to report a portion of their distributions as qualified business income eligible for the 20% deduction. However, until such relief is provided, non-corporate investors will not be able to receive the tax benefit that they would otherwise receive investing directly in the individual REIT securities.

Expense

Examples

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares, and (2) ongoing costs, including management fees and other applicable Fund expenses. The Examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

The Examples below are based on an investment of $1,000 invested at the beginning of the period and held through the period ended December 31, 2017.

The beginning of the period is July 1, 2017.

The information under “Actual Performance,” together with the amount you invested, allows you to estimate actual expenses incurred over the reporting period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.60) and multiply the result by the cost shown for your Fund in the row entitled “Expenses Incurred During Period” to estimate the expenses incurred on your account during this period.

The information under “Hypothetical Performance” provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expense you incurred for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Nushares Short-Term REIT ETF (NURE)

Expenses are equal to the Fund’s annualized net expense ratio of 0.35% multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

Financial Statements

1. General Information and Significant Accounting Policies

General Information

Trust and Fund Information

Nushares ETF Trust (the “Trust”) is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust is comprised of Nushares Short-Term REIT ETF (NURE) (the “Fund”), as a non-diversified fund, among others. The Trust was organized as a Massachusetts business trust on February 20, 2015. Shares of the Fund are listed and traded on the Cboe BZX Exchange, Inc. (formerly, BATS BZX Exchange, Inc.) (the “Exchange”).

The end of the reporting period for the Fund is December 31, 2017, and the period covered by these Notes to Financial Statements is the fiscal year ended December 31, 2017 (the “current fiscal period”).

Investment Adviser

The Fund’s investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). The Adviser has overall responsibility for management of the Fund, oversees the management of the Fund’s portfolio, manages the Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. The Adviser has entered into a sub-advisory agreement with Teachers Advisors, LLC (the “Sub-Adviser”), an affiliate of the Adviser, under which the Sub-Adviser manages the investment portfolio of the Fund.

Investment Objectives

The Fund seeks to track the investment results, before fees and expenses, of the Dow Jones U.S. Select Short-Term REIT Index (the “Index”).

The Fund’s most recent prospectus provides further description of the Fund’s investment objective, principal investment strategies and principal risks.

Significant Accounting Policies

The Fund is an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 946 “Financial Services – Investment Companies.” The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and losses from investment transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes.

Investment Income

Dividend income is recorded on the ex-dividend date.

Professional Fees

Professional fees presented on the Statement of Operations consist of fees and expenses of legal counsel to the Fund’s Board of Trustees (the “Board”).

Dividends and Distributions to Shareholders

Dividends from net investment income, if any, are declared and distributed to shareholders quarterly.

Net realized capital gains from investment transactions, if any, are declared and 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.

The tax character of Fund distributions for a fiscal year is dependent upon the amount and tax character of distributions received from securities held in the Fund’s portfolio. Distributions received from certain securities in which the Fund invests, most notably real estate investment trust (“REIT”) securities, may be characterized for tax purposes as ordinary income, long-term capital gain and/or a return of capital. The issuer of a security reports the tax character of its distributions only once per year, generally during the first two months of the calendar year. The distribution is included in the Fund’s ordinary income until such time the Fund is notified by the issuer of the actual tax character. For financial reporting purposes, dividend income,

net realized gain (loss) and unrealized appreciation (depreciation) recognized on the Statement of Operations reflect the amounts of income, capital gain, and/or return of capital as reported by the issuers of such securities for distributions during the current fiscal period.

Compensation

The Trust pays 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 Trust from the Adviser or its affiliates. The Board 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.

Indemnifications

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust enters into contracts that provide general indemnifications to other parties. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. However, the Trust has not had prior claims or losses pursuant to these contracts and expects 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 current fiscal period. Actual results may differ from those estimates.

2. Investment Valuation and Fair Value Measurements

The fair valuation input levels as described below are for fair value measurement purposes.

Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for 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 following is a summary of the three-tiered hierarchy of valuation input levels.

Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1. Securities primarily traded on the NASDAQ National Market (“NASDAQ”) are valued at the NASDAQ Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or NASDAQ for which there were no transactions on a given day or securities not listed on a securities exchange or NASDAQ are valued at the quoted bid price and 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 Board and/or its appointee 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 an independent pricing service (“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 the Fund’s net asset value (“NAV”) (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 observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.

Notes to Financial Statements (continued)

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund’s fair value measurements as of the end of the reporting period:

The Board is responsible for the valuation process and has appointed the oversight of the daily valuation process to the Adviser’s Valuation Committee. The Valuation Committee, pursuant to the valuation policies and procedures adopted by the Board, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies and reporting to the Board. The Valuation Committee is aided in its efforts by the Adviser’s dedicated Securities Valuation Team, which is responsible for administering the daily valuation process and applying fair value methodologies as approved by the Valuation Committee. When determining the reliability of independent pricing services for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of the pricing services and monitors the quality of security prices received through various testing reports conducted by the Securities Valuation Team.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making a fair value determination, based on the facts and circumstances specific to the portfolio instrument. Fair value determinations generally will be derived as follows, using public or private market information:

The purchase price of a portfolio instrument will be used to fair value the instrument only if no other valuation methodology is available or deemed appropriate, and it is determined that the purchase price fairly reflects the instrument’s current value.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such testing and fair valuation occurrences are reported to the Board.

3. Portfolio Securities and Investments in Derivatives

The Fund is authorized to invest in certain derivative instruments. The Fund records derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Fund’s investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.

Although the Fund is authorized to invest in derivative instruments, and may do so in the future, it did not make any such investments during the current fiscal period.

Market and Counterparty Credit Risk

In the normal course of business the 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 the Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of the 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.

The 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 the Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when the Fund has an unrealized loss, the Fund has instructed the custodian to pledge assets of the Fund 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 pre-determined threshold amount.

4. Fund Shares

The Fund issues and redeems its shares on a continuous basis at NAV only in aggregations of a specified number of shares or multiples thereof (“Creation Units”). Only certain institutional investors (referred to as “Authorized Participants”) who have entered into agreements with Nuveen Securities, LLC, the Fund’s distributor, may purchase and redeem Creation Units. Once created, shares of the Fund trade on the Exchange at market prices and are only available to individual investors through their brokers.

Creation Units are purchased and redeemed in-kind for a designated portfolio of securities included in the Fund’s Index and/or a specified amount of cash. Authorized Participants are charged fixed transaction fees in connection with purchasing and redeeming Creation Units. Authorized Participants transacting in Creation Units for cash may also pay an additional variable charge to compensate the Fund for certain transaction costs (i.e., taxes on currency or other financial transactions, and brokerage costs) and market impact expenses it incurs in purchasing or selling portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” on the Statements of Changes in Net Assets.

Transactions in Fund shares during current and prior fiscal period were as follows:

5. Investment Transactions

Long-term purchases and sales (excluding in-kind transactions) during the current fiscal period were as follows:

In-kind transactions during the current fiscal period were as follows:

6. Income Tax Information

The 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 Fund 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 Fund 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.

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. 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 NAV of the Fund.

The table below presents the cost and unrealized appreciation (depreciation) of the Fund’s investment portfolio, as determined on a federal income tax basis, as of December 31, 2017.

As of December 31, 2017, the Fund’s tax year end, the Fund did not have any permanent adjustments.

The tax components of undistributed net ordinary income and net long-term capital gains as of December 31, 2017, the Fund’s tax year end, were as follows:

Notes to Financial Statements (continued)

The tax character of distributions paid during the Fund’s tax years ended December 31, 2017 and December 31, 2016, was designated for purposes of the dividends paid deduction as follows:

7. Management Fees and Other Transactions with Affiliates

Management Fees

The annual management fee, payable monthly, is 0.35% of the average daily net assets of the Fund. The Fund’s management fee compensates the Adviser for its investment advisory services to the Fund. The Sub-Adviser is compensated for its services to the Fund from the management fees paid to the Adviser. The Adviser is responsible for substantially all other expenses of the Fund, except any future distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities, fees and expenses of the independent trustees (including any trustees’ counsel fees), certain compensation expenses of the Fund’s chief compliance officer, litigation expenses and extraordinary expenses.

Other Transactions with Affiliates

The Fund is permitted to purchase or sell securities from or to certain other funds or other accounts managed by the Sub-Adviser (“inter-fund trade”) under specified conditions outlined in procedures adopted by the Board. These procedures have been designed to ensure that any inter-fund trade of securities by the Fund from or to another fund or an account that is, or could be, considered an affiliate of the Fund under certain limited circumstances by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. Each inter-fund trade is effected at the current market price, determined in accordance with the procedures. Unsettled inter-fund trades as of the end of the reporting period are recognized as a component of “Receivable for investments sold” and/or “Payable for investments purchased” on the Statement of Assets and Liabilities, when applicable.

During the current fiscal period, the Fund engaged in inter-fund trades pursuant to these procedures as follows:

As of the end of the reporting period, TIAA owned shares of the Fund as follows:

Glossary of Terms

Used in this Report

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

Dow Jones U.S. Select REIT Index: The index tracks the performance of publicly traded REITs and REIT-like securities and is designed to serve as a proxy for direct real estate investment, in part by excluding companies whose performance may be driven by factors other than the value of real estate. The index is a subset of the Dow Jones U.S. Select Real Estate Securities Index (RESI), which represents equity real estate investment trusts (REITs) and real estate operating companies (REOCs) traded in the U.S. Index returns assume reinvestment of distributions, but do not include the effects of any applicable sales charges or management fees.

Dow Jones U.S. Select Short-Term REIT Index: The Index is composed of U.S. exchange-traded equity REITs that concentrate their holdings in apartment buildings, hotels, self-storage facilities and manufactured home properties, which typically have shorter lease durations than REITs that invest in other sectors. The Index is rebalanced on a quarterly basis and uses a rules-based methodology that weights REITs by market capitalization, subject to a 5% maximum weight per constituent. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

Gross Domestic Product (GDP): The total market value of all final goods and services produced in a country/region in a given year, equal to total consumer, investment and government spending, plus the value of exports, minus the value of imports.

Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding.

Real Estate Investment Trust (REIT): A REIT is a corporation or trust that invests in residential or commercial real estate.

Trustees

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

As of the end of the period covered by this report, the registrant’s Board of Directors or Trustees (“Board”) determined that the registrant has at least one “audit committee financial expert” (as defined in Item 3 of Form N-CSR) serving on its Audit Committee. The registrant’s audit committee financial experts are Carole E. Stone and Jack B. Evans, who are “independent” for purposes of Item 3 of Form N-CSR.

Ms. Stone served for five years as Director of the New York State Division of the Budget. As part of her role as Director, Ms. Stone was actively involved in overseeing the development of the State’s operating, local assistance and capital budgets, its financial plan and related documents; overseeing the development of the State’s bond-related disclosure documents and certifying that they fairly presented the State’s financial position; reviewing audits of various State and local agencies and programs; and coordinating the State’s system of internal audit and control. Prior to serving as Director, Ms. Stone worked as a budget analyst/examiner with increasing levels of responsibility over a 30 year period, including approximately five years as Deputy Budget Director. Ms. Stone has also served as Chair of the New York State Racing Association Oversight Board, as Chair of the Public Authorities Control Board, as a Commissioner on the New York State Commission on Public Authority Reform and as a member of the Boards of Directors of several New York State public authorities. These positions have involved overseeing operations and finances of certain entities and assessing the adequacy of project/entity financing and financial reporting. Currently, Ms. Stone is on the Board of Directors of CBOE Holdings, Inc., of the Chicago Board Options Exchange, and of C2 Options Exchange.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

The following tables show the amount of fees that KPMG LLP, the Funds’ auditor, billed to the Funds’ during the Funds’ last two full fiscal years. The Audit Committee approved in advance all audit services and non-audit services that KPMG LLP provided to the Funds, 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 preapproval exception for services provided directly to the Funds 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 Funds during the fiscal year in which the services are provided; (B) the Funds 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 Fees billed to Fund” for both fiscal year ends represent “Tax Fees” and “All Other Fees” billed to Fund in their respective amounts from the previous table.

Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.

“Non-Audit Fees billed to Fund” for both fiscal year ends represent “Tax Fees” and “All Other Fees” billed to Fund in their respective amounts from the previous table.

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