SUBJECT TO COMPLETION, DATED MARCH 21, 2017

TIAA Real Estate Account

A tax-deferred variable annuity option offered by Teachers Insurance and Annuity Association of America (“TIAA”)

This prospectus tells you about the TIAA Real Estate Account, an investment option offered through individual and group variable annuity contracts issued by TIAA. Please read it carefully before investing and keep it for future reference. The Real Estate Account, which we refer to sometimes as “the Account” in this prospectus, invests primarily in real estate and real estate-related investments. TIAA, one of the largest and most experienced mortgage and real estate investors in the nation, manages the Account’s assets.

The value of your investment in the Real Estate Account will go up or down depending on how the Account performs and you could lose money. The Account’s performance depends mainly on the value of the Account’s real estate and other real estate-related investments, the income generated by those investments and the Account’s expenses. The Account’s returns could go down if, for example, real estate values or rental and occupancy rates, or the value of real estate-related securities, decrease due to general economic conditions and/or a weak market for real estate generally. Property operating costs, costs associated with leverage on the Account’s properties, and government regulations, such as zoning or environmental laws, could also affect a property’s profitability. TIAA does not guarantee the investment performance of the Account, and you will bear the entire investment risk. For a detailed discussion of the specific risks of investing in the Account, see “Risk factors.”

We take deductions daily from the Account’s net assets for the Account’s operating and investment management expenses. The Account also pays TIAA for bearing mortality and expense risks and for providing a liquidity guarantee. The current estimated annual expense deductions from the Account’s net assets over the next 12 months total _____%.

The Real Estate Account is designed as an option for retirement and tax-deferred savings plans for employees of non-profit and governmental institutions. TIAA currently offers the Real Estate Account under the following annuity contracts:

Note that state regulatory approval may be pending for certain of these contracts and these contracts may not currently be available in your state. TIAA may also offer the Real Estate Account as an investment option under additional contracts, both at the individual and plan sponsor level, in the future.

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy of the information in this prospectus. Any representation to the contrary is a criminal offense.

An investment in the Real Estate Account is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

About the TIAA Real Estate Account

The TIAA Real Estate Account (the “Account”) was established in February 1995 as a separate account of Teachers Insurance and Annuity Association of America (“TIAA”) and interests in the Account were first offered to eligible participants on October 2, 1995. The Account offers individual and group accumulating annuity contracts (with contributions made on a pre-tax or after-tax basis), as well as individual lifetime and term-certain variable payout annuity contracts (including the payment of death benefits to beneficiaries). Investors are entitled to transfer funds to or from the Account under certain circumstances. Funds invested in the Account for each category of contract are expressed in terms of units, and unit values will fluctuate depending on the Account’s performance.

Investment objective

The Account seeks favorable long-term returns primarily through rental income and appreciation of real estate and real estate-related investments owned by the Account. The Account will also invest in non-real estate-related publicly traded securities and short-term higher quality liquid investments that are easily converted to cash to enable the Account to meet participant redemption requests, purchase or improve properties or cover other expense needs.

Investment strategy

Real Estate-Related Investments. The Account intends to have between 75% and 85% of its net assets invested directly in real estate or real estate-related investments with the goal of producing favorable long-term returns primarily through rental income and appreciation. These investments may consist of:

The Account’s principal strategy is to purchase direct ownership interests in income-producing real estate, primarily office, industrial, retail and multi-family properties. The Account is targeted to hold between 65% and 80% of the Account’s net assets in such direct ownership interests at any time. Historically, at least 70% of the Account’s net assets have comprised such direct ownership interests in real estate.

In addition, while the Account is authorized to hold up to 25% of its net assets in liquid real estate-related securities, such as publicly-traded REITs and CMBS, management intends that the Account will not hold more than 10% of its net assets in such securities on a long-term basis. Traditionally, less than 10% of the Account’s net assets have been comprised of interests in these securities; although, the Account has held approximately 10% of its net assets in equity REIT securities at times. In addition, under the Account’s current investment guidelines, the

Account is authorized to hold up to 10% of its net assets in CMBS. As of December 31, 2016 , REIT securities comprised approximately 4.4% of the Account’s net assets, and the Account held no CMBS as of such date.

Non-Real Estate-Related Investments. The Account will invest the remaining portion of its assets (targeted to be between 15% and 25% of its net assets) in publicly traded, liquid investments; namely:

However, from time to time, the Account’s non-real estate-related liquid investments may comprise less than 15% (and possibly less than 10%) of its assets (on a net basis and/or a gross basis), especially during and immediately following periods of significant net participant outflows, in particular due to significant participant transfer activity. In addition, the Account, from time to time and on a temporary basis, may hold in excess of 25% of its net assets in non-real estate-related liquid investments, particularly during times of significant inflows into the Account and/or a lack of attractive real estate-related investments available in the market.

Liquid Securities Generally. Primarily due to management’s need to manage fluctuations in cash flows, in particular during and immediately following periods of significant participant net transfer activity into or out of the Account, the Account may, on a temporary basis (i) exceed the upper end of its targeted holdings (currently 35% of the Account’s net assets) in liquid securities of all types, including both publicly traded non-real estate-related liquid investments and liquid real estate-related securities, such as REITs and CMBS, or (ii) be below the low end of its targeted holdings in such liquid securities (currently 15% of the Account’s net assets).

The portion of the Account’s net assets invested in liquid investments of all types may exceed the upper end of its target, for example, if (i) the Account receives a large inflow of money in a short period of time, in particular due to significant participant transfer activity into the Account, (ii) the Account receives significant proceeds from sales or financings of direct real estate assets, (iii) there is a lack of attractive direct real estate investments available on the market, and/or (iv) the Account anticipates more near-term cash needs, including to apply to acquire direct real estate investments, pay expenses or repay indebtedness.

Foreign Investments. The Account from time to time will also make foreign real estate investments. Under the Account’s investment guidelines, investments in direct foreign real estate, together with foreign real estate-related securities and foreign non-real estate-related liquid investments, may not comprise more than 25% of the Account’s net assets. However, through the date of this prospectus, such foreign real estate-related investments have never represented more than 7.5% of the Account’s net assets and management does not intend such foreign investments to exceed 10% of the Account’s net assets. As of December 31, 2016 , the Account did not have any foreign real estate investments.

Investments Summary. At December 31, 2016 , the Account’s net assets totaled $24.3 billion . As of that date, the Account’s investments in real estate properties, real estate joint ventures, limited partnerships, loans receivable and real estate-related marketable securities, net of the fair value of mortgage loans payable on real estate, represented 83.3% of the Account’s net assets.

At December 31, 2016 , the Account held a total of 129 real estate investments (including its interests in 24 real estate-related joint ventures), representing 79.1% of the Account’s total investments, measured on a gross asset value basis (“total investments”). As of that date, the Account also held investments in government agency notes (representing 8.7% of total investments), U.S. Treasury Securities (representing 6.5% of total investments), REIT equity securities (representing 4.1% of total investments), loans receivable (representing 1.1% of total investments) and real estate limited partnerships (representing 0.5% of total investments). See the Account’s audited consolidated financial statements for more information as to the Account’s investments as of December 31, 2016 .

Borrowing. The Account is authorized to borrow money in accordance with its investment guidelines. Under the Account’s current investment guidelines, management intends to maintain the Account’s loan to value ratio at or below 30%. The Account’s “loan to value ratio” at any time is based on the outstanding principal amount of the Account’s debt to the Account’s total gross asset value. This ratio will be measured at the time of any debt incurrence and will be assessed after giving effect thereto.

As of December 31, 2016 , the Account’s loan to value ratio was approximately 15.0% .

In addition, the Account may borrow up to 70% of the then-current value of a particular property. Non-construction mortgage loans on a property will be non-recourse to the Account. Please see the section below entitled “General investment and operating policies — Other real estate-related policies — Borrowing.”

Summary of expense deductions

Expense deductions are made each valuation day from the net assets of the Account for various services to manage the Account’s investments, administer the Account and the contracts, distribute the contracts, and to cover certain risks borne by TIAA. Investment management, administration and distribution services are provided “at cost” by TIAA and TIAA Individual & Institutional Services, LLC (“Services”), a registered broker-dealer and wholly owned subsidiary of TIAA. Currently, TIAA provides investment management services and administration services for the Account, and Services provides distribution services for the Account. In addition, TIAA charges the Account a fee to bear certain mortality and expense risks, and risks associated with providing the liquidity guarantee. TIAA guarantees that in the aggregate, the expense charges will never be more than 2.50% of average net assets per year.

The estimated annual expense deduction rate that appears in the following expense table reflects an estimate of the amount we currently expect to deduct to approximate the costs that the Account will incur from May 1, 2017 through April 30, 2018 . Actual expenses may be higher or lower. The expenses identified in the following table do not include any fees which may be imposed by your employer under a plan maintained by your employer.

Type of Expense Deduction	Estimated Percent of Net Assets Annually		Services Performed
Investment Management	____%		For investment advisory, investment management, portfolio accounting, custodial and similar services, including independent fiduciary and appraisal fees
Administration	____%		For administration and operations of the Account and the contracts, including administrative services such as receiving and allocating premiums and calculating and making annuity payments
Distribution	____%		For services and expenses associated with distributing the annuity contracts
Mortality and Expense Risk	____%		For TIAA’s bearing certain mortality and expense risks
Liquidity Guarantee	____%		For TIAA’s liquidity guarantee
Total Annual Expense Deduction 1,2	____ %		Total

Please see “Expense deductions” and “Selected financial data” for additional information.

TIAA currently does not impose a fee on transfers from the Account, but reserves the right to impose a fee on transfers from the Account in the future.

Example. The following table shows you an example of the expenses you would incur on a hypothetical investment of $10,000 in the TIAA Real Estate Account over several periods. The table assumes a 5% annual return on assets and an annual expense deduction equal to ____%. These figures do not represent actual expenses or investment performance, which may differ.

Summary risk factors

The value of your investment in the Account will fluctuate based on the value of the Account’s assets and the income the assets generate. You may lose money by investing in this Account. The Account’s assets and income can be affected by many factors, and you should consider the specific risks presented in this prospectus before investing in the Account. The principal risks include the following:

changes in political or economic conditions could effect such securities, which could negatively impact the value of the securities and the Account’s ability to dispose of a security at a favorable time; and

More detailed discussions of these risks and other risk factors associated with an investment in the Account are contained in the section below entitled “Risk factors.”

Valuing the Account’s assets

The assets of the Account are valued at the close of each valuation day and the Account calculates and publishes a unit value, which is available on TIAA’s website (www.tiaa.org), for each valuation day. The values of the Account’s properties are adjusted daily to account for capital expenditures and appraisals as they occur.

With respect to the Account’s real property investments, following the initial purchase of a property or the making of a mortgage loan on a property by the Account (at which time the Account normally receives an independent appraisal on such property), each of the Account’s real properties are appraised, and mortgage loans are valued, at least once every calendar quarter. Each of the Account’s real estate properties is appraised each quarter by an independent external state-certified (or its foreign equivalent) appraiser (which we refer to in this prospectus as an “independent appraiser”) who is a member of a professional appraisal organization. In addition, TIAA’s internal appraisal staff performs a review of each of these quarterly appraisals, in conjunction with the Account’s independent fiduciary, and TIAA’s internal appraisal staff or the independent fiduciary may request an additional appraisal or valuation outside of this quarterly cycle. Any differences in the conclusions of TIAA’s internal appraisal staff and the independent appraiser will be reviewed by the independent fiduciary, which will make a final determination on the matter (which may include ordering a subsequent independent appraisal).

In general, the Account obtains appraisals of its real estate properties spread out throughout the quarter, which is intended to result in appraisal adjustments and thus adjustments to the valuations of its holdings (to the extent adjustments are made) that happen regularly throughout each quarter and not on one specific day in each period. In addition, an estimated daily equivalent of net operating income is taken into consideration and is adjusted for actual transactional activity. The remaining assets in the Account are primarily marketable securities that are priced on a daily basis and are included in the Account’s daily unit value.

As of December 31, 2016 , the Account’s net assets totaled approximately $24.3 billion . Please see the section below entitled “Valuing the Account’s assets” for more information on how each class of the Account’s investments are valued.

Past performance

The bar chart and performance table below illustrate how investment performance during the accumulation period has varied. The chart shows the Account’s total return (which includes all expenses) during the accumulation period over each of the last ten calendar years. It also shows the Account’s returns during the accumulation period for the one-, three-, five- and ten-year periods through December 31, 2016 . These returns represent the total return during each such year and reflect both the Account’s investment income and capital appreciation from the Account’s total investments during each such year.

How the Account has performed in the past is not necessarily an indication of how it will perform in the future. Please see “Risk factors” below.

Best quarter: 5.68%, for the quarter ended December 31, 2010.

Worst quarter: –13.18%, for the quarter ended December 31, 2008.

About TIAA and TIAA’s role with the Account

TIAA was founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and offers traditional annuities. In addition to the Account, TIAA also offers other variable annuities (through certain other insurance separate accounts) that invest in equity investments directly as well as in mutual funds that invest in equities and fixed-income investments.

TIAA is the companion organization of CREF, the first company in the United States to issue a variable annuity. CREF is a non-profit membership corporation established in New York State in 1952. Together, TIAA and CREF, form the principal retirement system for the nation’s education and research communities and form one of the largest pension systems in the U.S., based on assets under management. As of December 31, 2016 , TIAA’s total statutory admitted assets were approximately $282 billion; the combined assets under management for TIAA, CREF and other entities within the TIAA organization (including TIAA-sponsored mutual funds) totaled approximately $907 billion. CREF does not stand behind TIAA’s guarantees and TIAA does not guarantee CREF products.

The Account does not have officers, directors or employees. TIAA employees, under the direction and control of TIAA’s Board of Trustees (the “Board”) and its Investment Committee, manage the investment of the Account’s assets, following investment management procedures TIAA has adopted for the Account. In addition, TIAA performs administration functions for the Account (which include receiving and allocating premiums, calculating and making annuity payments and providing recordkeeping and other services). Distribution services for the Account (which include, without limitation, distribution of the annuity contracts, advising existing annuity contract owners in connection with their accumulations and helping employers implement and manage retirement plans) are performed by Services. TIAA and Services provide investment management, administration and distribution services, as applicable, to the Account on an “at-cost” basis.

With over 65 years in the real estate business and interests in properties located across the U.S. and internationally, TIAA is one of the nation’s largest and most experienced investors in mortgages and real estate equity interests. As of December 31, 2016 , the TIAA General Account had a mortgage and real property portfolio (including interests in TIAA subsidiaries that hold real estate, real estate funds and joint ventures but excluding mortgage-backed securities and REIT securities) valued at approximately $29.3 billion.

Liquidity Guarantee . In the event that the Account’s level of liquidity is not sufficient to guarantee that Account participants may redeem their accumulation units (at their accumulation unit value as of the date of such redemption

request received in good order), the TIAA General Account will purchase accumulation units issued by the Account (sometimes called “liquidity units”) in accordance with its liquidity guarantee. The cost of this guarantee is embedded in the overall expense charge of the Account. This liquidity guarantee is not a guarantee of either investment performance or the value of units in the Account.

This liquidity guarantee was first exercised in December 2008 and between December 2008 and June 2009, approximately $1.2 billion in liquidity units in the aggregate were purchased. The liquidity guarantee has not been exercised since June 2009. The independent fiduciary has since completed the systematic redemption of all of the liquidity units held by the TIAA General Account. Approximately one-quarter of such units were redeemed evenly over the business days in each of June, September and December 2012, and March 2013, representing a total of $1.3 billion redeemed during this period. Please see the sections entitled “Establishing and managing the Account — The role of TIAA — Liquidity guarantee” and “— Role of the independent fiduciary.”

The contracts

TIAA offers the Account as a variable option for the annuity contracts listed on the inside cover page of this prospectus, although some employer plans may not offer the Account as an option for certain contracts. Each payment to the Account buys a number of accumulation units. Similarly, any transfer or withdrawal from the Account results in the redemption of a number of accumulation units. The price you pay for an accumulation unit, and the price you receive for an accumulation unit when you redeem accumulation units, is the accumulation unit value (“AUV”) calculated for the business day on which we receive your purchase, redemption or transfer request in good order (unless you ask for a later date for a redemption or transfer).

The Right to Cancel Your Contract. Generally, you may cancel any RA, SRA, GSRA, Classic IRA, Roth IRA, ATRA or Keogh contract in accordance with the contract’s Right to Examine provision (unless we have begun making annuity payments from it) and subject to the time period regulated by the state in which the contract is issued. Although the contract terms and state law provisions differ, you will generally have between 10 and 60 days to exercise this cancellation right.

Transfers and Withdrawals. Subject to the terms of the contracts and your employer’s plan, you can move your money to and from the Account in the following ways, among others:

Importantly, transfers out of the Account to a TIAA or CREF account or into another investment option can be executed on any business day but are limited to once per calendar quarter, although some plans may allow systematic transfers that result in more than one transfer per calendar quarter. Other limited exceptions may apply. Also, transfers to CREF accounts or to certain other options may be restricted by your employer’s plan, current tax law or by the terms of your contract.

In addition, individual participants are limited from making internal funding vehicle transfers into their Account accumulation if, after giving effect to such transfer, the total value of such participant’s Account accumulation (under all contracts issued to such participant) would exceed $150,000. Categories of transactions that TIAA deems “internal funding vehicle transfers” for purposes of this limitation are described in detail in the section below entitled “Restrictions on premiums and transfers to the Account.” As of the date of this prospectus, all jurisdictions in which the Account is offered have approved this limitation, but the effective date of the limitation as applies to an individual participant will be reflected on his or her applicable contract or endorsement form. Please see the section entitled “How to transfer and withdraw your money.”

By limiting these transfers to the Real Estate Account, as anticipated, the amount of funds going into and out of the Account has become more predictable, which we believe will continue to enhance our ability to invest and manage the Real Estate Account’s portfolio with a long-term perspective. Please see the section entitled “Management’s discussion and analysis of the Account’s financial condition and results of operations — Liquidity

and capital resources" incorporated by reference from the Account's Annual Report on Form 10-K for the fiscal year ended December 31, 2016, and filed on March 20, 2017, for a discussion of participant flow activity.

The Annuity Period . Your income payments may be paid out of the Account through a variety of income options. Ordinarily, your annuity payments begin on the date you designate as your annuity starting date, subject to the terms of your employer’s plan. Your initial income payments are based on the value of your accumulation on the last valuation day before the annuity starting date and annuity payments can change after the initial payment based on the Account’s investment experience, the income option you choose and the income change method you choose. Important tax considerations may also apply. Please see the section below entitled “When you are ready to receive annuity income”

Death Benefits . Subject to the terms of your employer’s plan, TIAA may pay death benefits if you or your annuity partner dies. When you purchase your annuity contract, you name one or more beneficiaries to receive the death benefit if you die. You can change your beneficiaries any time before you die, and, unless you instruct otherwise, your annuity partner can do the same after your death. Your choice of beneficiary for death benefits may, in some cases, be subject to the consent of your spouse and federal and state law may impose additional restrictions. If you die during the accumulation period, the death benefit is the amount of your accumulation. If you and your annuity partner die during the annuity period while payments are still due under a fixed-period annuity or for the remainder of a guaranteed period, the death benefit is the present value, based on interest at the effective annual rate of 4%, of the unit annuity payments due for the remainder of the period. Death benefits may be paid out during the accumulation period (currently under one of five available methods) or during the annuity period. Ordinarily, death benefits are subject to federal estate tax. Generally, if taken as a lump sum, death benefits would be taxed like complete withdrawals. If taken as annuity benefits, death benefits would be taxed like annuity payments. See the section below entitled “Death benefits.”

Risk factors

The value of your investment in the Account will fluctuate based on the value of the Account’s assets, the income the assets generate and the Account’s expenses. Participants can lose money by investing in the Account. The past performance of the Account is not indicative of future results . There is risk associated with an investor attempting to “time” an investment in the Account’s units, or effecting a redemption of an investor’s units. The Account’s assets and income can be affected by many factors, and you should consider the specific risks presented below before investing in the Account. In particular, for a discussion of how forward-looking statements contained in this prospectus and that are incorporated by reference from the 2016 Form 10-K are subject to uncertainties that are difficult to predict, which may be beyond management’s control and which could cause actual results to differ materially from historical experience or management’s present expectations, please refer to the subsection below in the Account's 10-K for the fiscal year ended December 31, 2016, filed on March 20, 2017 entitled “Forward-looking statements.”

Forward-looking statements

Some statements in this prospectus (including statements incorporated by reference from the Account’s 2016 Form 10-K) which are not historical facts may be “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements about management’s expectations, beliefs, intentions or strategies for the future, include the assumptions and beliefs underlying these forward-looking statements, and are based on current expectations, estimates and projections about the real estate industry, domestic and global economic conditions, including conditions in the credit and capital markets, the sectors, and markets in which the Account invests and operates, and the transactions described in this prospectus. While management believes the assumptions underlying any of its forward-looking statements and information to be reasonable, such information may be subject to uncertainties and may involve certain risks which may be difficult to predict and are beyond management’s control. These risks and uncertainties could cause actual results to differ materially from those contained in any forward-looking statement. These risks and uncertainties include, but are not limited to, the following :

Risks associated with real estate investing

General Risks of Acquiring and Owning Real Property: As referenced elsewhere in this prospectus, the substantial majority of the Account’s net assets consist of direct ownership interests in real estate. As such, the

Account is particularly subject to the risks inherent in acquiring and owning real property, including in particular the following:

The incidence of some or all of these factors could reduce occupancy, rental rates and the fair value of the Account’s real properties or interests in investment vehicles (such as limited partnerships) which directly hold real properties.

In addition, the Account owns and operates a number of properties in the Washington, DC metropolitan area and a prolonged period of significantly diminished federal expenditures could have an adverse impact on demand for office space by the U.S. government and the sectors and industries dependent upon the U.S. government in such region or other regions where the government or such related businesses are large lessees.

If any or all of these events occur, the Account’s income and performance may be adversely impacted disproportionately by deteriorating economic conditions in those areas or industry sectors in which the Account’s investments are concentrated. Also, the Account could experience a more rapid negative change in the value of its real estate investments than would be the case if its real estate investments were more diversified.

substantial expenditures for tenant improvements and other lease-up related costs, while still being obligated for any mortgage payments, real estate taxes and other expenditures related to the property.

In addition, the Account’s properties may be located close to properties that are owned by other real estate investors and that compete with the Account for tenants. These competing properties may be better located, more suitable for tenants than our properties, or have owners who may compete more aggressively for tenants, resulting in a competitive advantage for these other properties. We may also face similar competition from other properties that may be developed in the future. This competition may limit the Account’s ability to lease space, increase its costs of securing tenants, and limit our ability to maximize our rents and/or require the Account to make capital improvements it otherwise would not, in order to make its properties more attractive to prospective tenants.

uninsurable or not insurable to the full extent of the loss suffered. Moreover, any of these events could cause consumer confidence and spending to decrease or result in increased volatility in the United States, worldwide financial markets, and the global economy. Such events could also result in economic uncertainty in the United States or abroad. Adverse economic conditions resulting from terrorist activities could reduce demand for space in the Account’s properties and thereby reduce the value of the Account’s properties and therefore your investment return.

General Risks of Selling Real Estate Investments: Among the risks of selling real estate investments are:

Valuation and Appraisal Risks: Investments in the Account’s assets are stated at fair value, which is defined as the price that would be received to sell the asset in an orderly transaction between market participants at the measurement date. Determination of fair value, particularly for real estate assets, involves significant judgment. Valuation of the Account’s real estate properties (which comprise a substantial majority of the Account’s net assets) are based on real estate appraisals, which are estimates of property values based on a professional’s opinion and may not be accurate predictors of the amount the Account would actually receive if it sold a property. Appraisals can be subjective in certain respects and rely on a variety of assumptions and conditions at that property or in the market in which the property is located, which may change materially after the appraisal is conducted. Among other things, market prices for comparable real estate may be volatile, in particular if there has been a lack of recent transaction activity in such market. Any future disruptions in the macroeconomy, real estate markets and the credit markets, such as those that occurred from 2008-2011, could lead to a significant decline in real estate transaction activity in most markets and sectors in which the Account is invested.  The resulting lack of observable transaction data may make it more difficult for a property appraisal to determine the fair value of the Account’s investment in one or more real estate assets. In addition, a portion of the data used by appraisers is based on historical information at the time the appraisal is conducted, and subsequent changes to such data, after an appraiser has used such data in connection with the appraisal, may not be adequately captured in the appraised value. Also, to the extent that the Account uses a relatively small number of independent appraisers to value a significant portion of its properties, valuations may be subject to any institutional biases of such appraisers and their valuation procedures.

Further, as the Account generally obtains appraisals on a quarterly basis, there may be circumstances in the period between appraisals or interim valuation adjustments in which the true realizable value of a property is not reflected in the Account’s daily net asset value calculation or in the Account’s periodic consolidated financial statements. This disparity may be more apparent when the commercial and/or residential real estate markets experience an overall and possibly dramatic decline (or increase) in property values in a relatively short period of time between appraisals.

If the appraised values of the Account’s properties as a whole are too high, those participants who purchased accumulation units prior to (i) a downward valuation adjustment of a property or multiple properties or (ii) a property or properties being sold for a lower price than the appraised value will be credited with less of an interest than if the value had previously been adjusted downward. Also, those participants who redeem during any such period will have received more than their pro rata share of the value of the Account’s assets, to the detriment of other non-redeeming participants. In particular, appraised property values may prove to be too high (as a whole) in a rapidly declining commercial real estate market. Further, implicit in the Account’s definition of fair value is a principal assumption that there will be a reasonable time to market a given property and that the property will be exchanged between a willing buyer and willing seller in a non-distressed scenario. However, an appraised value may not reflect the actual realizable value that would be obtained in a rush sale where time was of the essence. Also, appraised values may lag actual realizable values to the extent there is significant and rapid economic deterioration in a particular geographic market or a particular sector within a geographic market.

If the appraised values of the Account’s properties as a whole are too low, those participants who redeem prior to (i) an upward valuation adjustment of a property or multiple properties or (ii) a property or properties being sold for a higher price than the appraised value will have received less than their pro rata share of the value of the Account’s assets, and those participants who purchase units during any such period will be credited with more than their pro rata share of the value of the Account’s assets.

Finally, the Account recognizes items of income (such as net operating income from real estate investments, distributions from real estate limited partnerships or joint ventures, or dividends from REIT stocks) and expense in many cases on an intermittent basis, where the Account cannot predict with certainty the magnitude or the timing of such items. As such, even as the Account estimates items of net operating income on a daily basis, the AUV for the Account may fluctuate, perhaps significantly, from day to day, as a result of adjusting these estimates for the actual recognized item of income or expense.

Investment Risk Associated with Participant Transactions: The amount the Account has available to invest in new properties and other real estate-related assets will depend, in large part, on the level of net participant transfers into or out of the Account as well as participant premiums into the Account. As noted elsewhere in this prospectus, the Account intends to hold between 15% and 25% of its net assets in publicly traded, liquid investments (other than real estate and real estate-related investments), consisting of publicly traded, liquid investments. These liquid assets are intended to be available to purchase real estate-related investments in accordance with the Account’s investment objective and strategy and are also available to meet participant redemption requests and the Account’s expense needs (including, from time to time, obligations on debt). Significant participant transaction activity into or out of the Account’s units is generally not predictable, and wide fluctuations can occur as a result of macroeconomic or geopolitical conditions, the performance of equities or fixed income securities or general investor sentiment, regardless of the historical performance of the Account or of the performance of the real estate asset class generally.

In the second half of 2008 and in 2009, the Account experienced significant net participant transfers out of the Account, eventually causing the Account’s liquid assets to comprise less than 10% of the Account’s assets (on a net and total basis) throughout all of 2009 and into early 2010. Due in large part to this activity, the TIAA liquidity guarantee was initially executed in December 2008. Please see the section below entitled “Establishing and managing the Account — The role of TIAA — Liquidity guarantee.” Among other things, this continued shortfall in the amount of liquid assets impaired management’s ability to consummate new transactions. If a significant amount of net participant transfers out of the Account were to recur, particularly in high volumes similar to those experienced in late 2008 and 2009, the Account may not have enough available liquid assets to pursue, or consummate, new investment opportunities presented to us that are otherwise attractive to the Account. This, in turn, could harm the Account’s returns. Even though net transfers out of the Account ceased in early 2010 and, as of the date of this prospectus, the Account has been in a net inflow position since such time, there is no guarantee that redemption activity will not increase again, perhaps in a significant and rapid manner.

Alternatively, periods of significant net transfer activity into the Account can result in the Account holding a higher percentage of its net assets in publicly traded liquid non-real estate-related investments than the Account’s

managers would target to hold under the Account’s long-term strategy. As of December 31, 2016 , the Account’s non-real estate-related liquid assets comprised 16.7% of its net assets. At times, the portion of the Account’s net assets invested in these types of liquid instruments may exceed 25%, particularly if the Account receives a large inflow of money in a short period of time, coupled with a lack of attractive real estate- related investments on the market. Also, large inflows from participant transactions often occur in times of appreciating real estate values and pricing, which can render it challenging to execute on some transactions at ideal prices.

In an appreciating real estate market generally, this large percentage of assets held in liquid investments and not in real estate and real estate-related investments may impair the Account’s overall returns. This scenario may be exacerbated in a low interest rate environment for U.S. Treasury securities and related highly liquid securities, such as has existed since 2009 and which may persist in the future. In addition, to manage cash flow, the Account may temporarily hold a higher percentage of its net assets in liquid real estate-related securities, such as REIT and CMBS securities, than its long-term targeted holdings in such securities, particularly during and immediately following times of significant net transfer activity into the Account. Such holdings could increase the volatility of the Account’s returns.

Risks of Borrowing: The Account acquires some of its properties subject to existing financing and from time to time borrows new funds at the time of purchase. Also, the Account may from time to time place new leverage on, increase the leverage already placed on, or refinance maturing debt on, existing properties the Account owns. Under the Account’s current investment guidelines, the Account intends to maintain its loan to value ratio at or below 30% (measured at the time of incurrence and after giving effect thereto). As of December 31, 2016 , the Account’s loan to value ratio was approximately 15.0% . Also, the Account may borrow up to 70% of the then-current value of a particular property. Non-construction mortgage loans on a property will be non-recourse to the Account.

Among the risks of borrowing money or otherwise investing in a property subject to a mortgage are:

the loan term, or otherwise obtain adequate refinancing on terms commercially acceptable to the Account or at all. The Account then may be forced to sell the property or other properties under unfavorable market conditions, restructure the loan on terms not advantageous to the Account, or default on its mortgage, resulting in the lender exercising its remedies, which may include repossession of the property, and the Account could lose the value of its investment in that property.

A general disruption in the credit markets, such as the disruption experienced in 2008 and 2009, may aggravate some or all of these risks.

Risks of Joint Ownership: Investing in joint venture partnerships or other forms of joint property ownership may involve special risks, many of which are exacerbated when the consent of parties other than the Account is required to take action.

Risks of Developing or Redeveloping Real Estate or Buying Recently Constructed Properties: If the Account chooses to develop or redevelop a property or buys a recently constructed property, it may face the following risks:

Risks with Purchase-Leaseback Transactions: To the extent the Account invested in a purchase-leaseback transaction, the major risk is that the third party lessee will be unable to make required payments to the Account. If the leaseback interest is subordinate to other interests in the real property, such as a first mortgage or other lien, the risk to the Account increases because the lessee may have to pay the senior lienholder to prevent foreclosure before it pays the Account. If the lessee defaults or the leaseback is terminated prematurely, the Account might not recover its investment unless the property is sold or leased on favorable terms.

Real Estate Regulatory Risks: Government regulation at the federal, state and local levels, including, without limitation, zoning laws, rent control or rent stabilization laws, laws regulating housing on the Account’s multi-family properties, the Americans with Disabilities Act, property taxes and fiscal, accounting, environmental or other government policies, could operate or change in a way that adversely affects the Account and its properties. For example, these regulations could raise the cost of acquiring, owning, improving or maintaining properties, present barriers to otherwise desirable investment opportunities or make it harder to sell, rent, finance, or refinance properties either on economically desirable terms, or at all, due to the increased costs associated with regulatory compliance.

Environmental Risks: The Account may be liable for damage to the environment or injury to individuals caused by hazardous substances used or found on its properties. Under various environmental regulations, the Account may also be liable, as a current or previous property owner or mortgagee, for the cost of removing or cleaning up hazardous substances found on a property, even if it did not know of and wasn’t responsible for the hazardous substances. If any hazardous substances are present or the Account does not properly clean up any hazardous substances, or if the Account fails to comply with regulations requiring it to actively monitor the business activities on its premises, the Account may have difficulty selling or renting a property or be liable for monetary penalties. Further, environmental laws may impose restrictions on the manner in which a property may be used, the tenants which may be allowed, or the manner in which businesses may be operated, which may require the Account to expend funds in order to comply with these laws. These laws may also cause the most ideal use of the property to differ from that originally contemplated and as a result could impair the Account’s returns. The cost of any required clean-up relating to a single real estate investment (including remediating contaminated property) and the Account’s

potential liability for environmental damage, including paying personal injury claims and performing under indemnification obligations to third parties, could exceed the value of the Account’s investment in a property, the property’s value, or in an extreme case, a significant portion of the Account’s assets. Finally, while the Account may from time to time acquire third-party insurance related to environmental risks, such insurance coverage may be inadequate to cover the full cost of any loss and would cause the Account to be reliant on the financial health of our third-party insurer at the time any such claim is submitted.

Uninsurable Losses: Certain catastrophic losses ( e.g. , from earthquakes, wars, terrorist acts, nuclear accidents, hurricanes, wind, floods or environmental or industrial hazards or accidents) may be uninsurable or so expensive to insure against that it is economically disadvantageous to buy insurance for them. Further, the terms and conditions of the insurance coverage the Account has on its properties, in conjunction with the type of loss actually suffered at a property, may subject the property, or the Account as a whole, to a cap on insurance proceeds that is less than the loss or losses suffered. If a disaster that we have not insured against occurs, if the insurance contains a high deductible, and/or if the aggregate insurance proceeds for a particular type of casualty are capped, the Account could lose some of its original investment and any future profits from the property. Also, the Account may not have sufficient access to internal or external sources of funding to repair or reconstruct a damaged property to the extent insurance proceeds do not cover the full loss. In addition, some leases may permit a tenant to terminate its obligations in certain situations, regardless of whether those events are fully covered by insurance. In that case, the Account would not receive rental income from the property while that tenant’s space is vacant, and any such vacancy might impact the value of that property. Finally, as with respect to all third-party insurance, we are reliant on the continued financial health of such insurers and their ability to pay on valid claims. If the financial health of an insurer were to deteriorate quickly, we may not be able to find adequate coverage from another carrier on favorable terms, which could adversely impact the Account’s returns.

Risks of investing in real estate investment trust securities

The Account invests in registered and unregistered REIT securities for diversification, liquidity management and other purposes. The Account’s investment in REITs may also increase, as a percentage of net assets, during periods in which the Account is experiencing large net inflow activity, in particular due to net participant transfers into the Account. As of December 31, 2016, REIT securities comprised approximately 4.4% of the Account’s net assets. Investments in REIT securities are part of the Account’s real estate-related investment strategy and are subject to many of the same general risks associated with direct real property ownership. In particular, equity REITs may be affected by changes in the value of the underlying properties owned by the entity, while mortgage REITs may be affected by the quality of any credit extended. In addition to these risks, because REIT investments are securities and generally publicly traded, they may be exposed to market risk and potentially significant price volatility due to changing conditions in the financial markets and, in particular, changes in overall interest rates, regardless of the value of the underlying real estate such REIT may own. Also, sales of REIT securities by the Account for liquidity management purposes may occur at times when values of such securities have declined and it is otherwise an inopportune time to sell the security. Volatility in REITs can cause significant fluctuations in the Account’s AUV on a daily basis, as they are correlated to equity markets which have experienced significant day to day fluctuations over the past few years.

REITs do not pay federal income taxes if they distribute most of their earnings to their shareholders and meet other tax requirements. Many of the requirements to qualify as a REIT, however, are highly technical and complex. Failure to qualify as a REIT results in tax consequences, as well as disqualification from operating as a REIT for a period of time. Consequently, if the Account invests in securities of a REIT that later fails to qualify as a REIT, this may adversely affect the performance of our investment.

Risks of mortgage-backed securities

The Account from time to time has invested in mortgage-backed securities and may in the future invest in such securities. Mortgage-backed securities, such as CMBS, are subject to many of the same general risks inherent in real estate investing, making mortgage loans and investing in debt securities. The underlying mortgage loans may experience defaults with greater frequency than projected when such mortgages were underwritten, which would impact the values of these securities, and could hamper our ability to sell such securities. In particular, these types of investments may be subject to prepayment risk or extension risk ( i.e., the risk that borrowers will repay the loans earlier or later than anticipated). If the underlying mortgage assets experience faster than anticipated prepayments of principal, the Account could fail to recoup some or all of its initial investment in these securities, since the original price paid by the Account was based in part on assumptions regarding the receipt of interest payments. If the

underlying mortgage assets are repaid later than anticipated, the Account could lose the opportunity to reinvest the anticipated cash flows at a time when interest rates might be rising. The rate of prepayments depends on a variety of geographic, social and other functions, including prevailing market interest rates and general economic factors. Further, it is possible that the U.S. Government may change its support of, and policies regarding, Fannie Mae and Freddie Mac and, thus, the Account may be unable to acquire agency mortgage-backed securities in the future and even if the Account so acquired them, such changes may result in a negative effect on the pricing of such securities. Other policy changes impacting Fannie Mae and Freddie Mac and/or U.S. Government programs related to mortgages that may be implemented in the future could create market uncertainty and affect the actual or perceived credit quality of issued securities, adversely affecting mortgage- backed securities through an increased risk of loss.

Importantly, the fair market value of these securities is also highly sensitive to changes in interest rates, liquidity of the secondary market and economic conditions impacting financial institutions and the credit markets generally. Note that the potential for appreciation, which could otherwise be expected to result from a decline in interest rates, may be limited by any increased prepayments. Further, volatility and disruption in the mortgage market and credit markets generally (such as was the case in 2008 and 2009) may cause there to be a very limited or even no secondary market for these securities and they therefore may be harder to sell than other securities.

Risks of U.S. government agency securities and corporate obligations

The Account invests in securities issued by U.S. government agencies and U.S. government-sponsored entities. Some of these issuers may not have their securities backed by the full faith and credit of the U.S. government, which could adversely affect the pricing and value of such securities. Also, the Account may invest in corporate obligations (such as commercial paper) and while the Account seeks out such holdings in short-term, higher-quality liquid instruments, the ability of the Account to sell these securities may be uncertain, particularly when there are general dislocations in the finance or credit markets. Any such volatility could have a negative impact on the value of these securities. Further, transaction activity may fluctuate significantly from time to time, which could impair the Account’s ability to dispose of a security at a favorable time, regardless of the credit quality of the underlying issuer. Also, inherent with investing in any corporate obligation is the risk that the credit quality of the issuer will deteriorate, which could cause the obligations to be downgraded and hamper the value or the liquidity of these securities. Finally, any further downgrades or threatened downgrades of the credit rating for U.S. government obligations generally could impact the pricing and liquidity of agency securities or corporate obligations in a manner which could impact the value of the Account’s units.

Risks of liquid investments

The Account’s investments in liquid investments (whether real estate-related, such as REITs, CMBS or some loans receivable, or non-real estate-related, such as cash equivalents and government securities, and whether debt or equity), are subject to the following general risks:

Further, to the extent that a significant portion of the Account’s net assets at any particular time consist of cash, cash equivalents and non-real estate-related liquid securities, the Account’s returns may suffer as compared to the return that could have been generated by more profitable real estate-related investments. Such a potential negative impact on returns may be exacerbated in times of low prevailing interest rates payable on many classes of liquid securities, such as is the case as of the date hereof and which may persist in the future.

Risks of foreign investments

In addition to other investment risks noted above, foreign investments present the following special risks:

Risks of investing in mortgage loans and related investments

The Account’s investment strategy includes, to a limited extent, investments in mortgage loans ( i.e., the Account serving as lender).

must rely solely on the value of a property for its security. In addition, there is a risk of delay in exercising any contractual remedies due to actions of the borrower, including, without limitation, bankruptcy or insolvency of the borrower.

Any of these circumstances may result in the Account being unable to recover some or all of its original investment.

Risks of Securities Lending

As described more fully in “Securities Lending” below, in lending its securities, the Account bears the market risk with respect to the investment of collateral and the risk the borrower or Agent may default on its contractual obligations to the Account. Each Agent bears the risk that the borrower may default on its obligation to return the loaned securities as the Agent is contractually obligated to indemnify the Account if at the time of a default by a borrower some or all of the loaned securities have not been returned.

Conflicts of interest within TIAA

General: TIAA and its affiliates (including TIAA-CREF Alternatives Advisors, LLC and Teachers Advisors, LLC, its wholly owned subsidiaries and registered investment advisers, and TH Real Estate Global, LLC ("THRE"), its wholly-owned subsidiary) have interests in other real estate programs and accounts and also engage in other business activities. As such, they will have conflicts of interest in allocating their time between the Account’s business and these other activities. Also, the Account may be buying properties at the same time as TIAA affiliates that may have similar investment objectives to those of the Account. There is also a risk that TIAA will choose a property that provides lower returns to the Account than a property purchased by TIAA and its affiliates. Further, the Account will likely acquire properties in geographic areas where TIAA and its affiliates own or manage properties. In addition, the Account may desire to sell a property at the same time another TIAA affiliate is selling a property in an overlapping market. Conflicts could also arise because some properties owned or managed by TIAA and its affiliates may compete with the Account’s properties for tenants. Among other things, if one of the TIAA entities attracts a tenant that the Account is competing for, the Account could suffer a loss of revenue due to delays in locating another suitable tenant. TIAA has adopted allocation policies and procedures applicable to the purchasing conflicts scenario, but the resolution of such conflicts may be economically disadvantageous to the Account. As a result of TIAA’s and its affiliates’ obligations to TIAA itself and to other current and potential investment vehicles sponsored by TIAA affiliates with similar objectives to those of the Account, there is no assurance that the Account will be able to take advantage of every attractive investment opportunity that otherwise is in accordance with the Account’s investment objectives.

Liquidity Guarantee: In addition, as discussed elsewhere in this prospectus, the TIAA General Account provides a liquidity guarantee to the Account. While an independent fiduciary is responsible for establishing a “trigger point” (a percentage of TIAA’s ownership of liquidity units beyond which TIAA’s ownership may be reduced at the fiduciary’s direction), there is no express cap on the amount TIAA may be obligated to fund under this guarantee. Further, the Account’s independent fiduciary oversees any redemption of TIAA liquidity units. TIAA’s ownership of liquidity units (including the potential for changes in its levels of ownership in the future) from time to time could result in the perception that TIAA is taking into account its own economic interests while serving as investment manager for the Account. In particular, the value of TIAA’s liquidity units fluctuates in the same manner as the value of accumulation units held by all participants. Any perception of a conflict of interest could cause participants to transfer accumulations out of the Account to another investment option, which could have an adverse impact on the Account’s ability to act most optimally upon its investment strategy. For a discussion of the relevant allocation policies and procedures TIAA has established, as well as a summary of other conflicts of interest which may arise as a result of TIAA’s management of the Account, see the section entitled “Establishing and managing the Account — The role of TIAA — Conflicts of interest.”

No opportunity for prior review of transactions

Investors do not have the opportunity to evaluate the economic or financial merit of the purchase, sale or financing of a property or other investment before the Account completes the transaction, so investors will need to rely solely on TIAA’s judgment and ability to select investments consistent with the Account’s investment objective and policies. Further, the Account may change its investment objective and pursue specific investments in accordance with any such amended investment objective without the consent of the Account’s investors.

Risks of registration under the Investment Company Act of 1940

The Account has not registered, and management intends to continue to operate the Account so that it will not have to register, as an “investment company” under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Generally, a company is an “investment company” and required to register under the Investment Company Act if, among other things, it holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities, or it is engaged or proposes to engage in the business of investing, reinvesting, owning, holding or trading in securities and owns or proposes to acquire investment securities having a value exceeding 40% of the value of such company’s total assets (exclusive of government securities and cash items) on an unconsolidated basis.

If the Account were obligated to register as an investment company, the Account would have to comply with a variety of substantive requirements under the Investment Company Act that impose, among other things, limitations on capital structure, restrictions on certain investments, compliance with reporting, record keeping, voting and proxy disclosure requirements and other rules and regulations that could significantly increase its operating expenses and reduce its operating flexibility. To maintain compliance with the exemptions from the Investment Company Act, the Account may be unable to sell assets it would otherwise want to sell and may be unable to purchase securities it would otherwise want to purchase, which might materially adversely impact the Account’s performance.

Cybersecurity risks

With the increased use of technologies such as the Internet to conduct business, the Account and its service providers (including, but not limited to, TIAA, Services, the independent fiduciary and the Account’s custodian and financial intermediaries) are susceptible to cybersecurity risks. In general, cyber-security attacks can result from infection by computer viruses or other malicious software or from deliberate actions or unintentional events, including gaining unauthorized access through “hacking” or other means to digital systems, networks, or devices that are used to service the Account’s operations in order to misappropriate assets or sensitive information, corrupt data, or cause operational disruption. Cybersecurity attacks can also be carried out in a manner that does not require gaining unauthorized access, including by carrying out a “denial-of-service” attack on the Account or its service providers’ websites. In addition, authorized persons could inadvertently or intentionally release and possibly destroy confidential or proprietary information stored on the Account’s systems or the systems of its service providers.

Cybersecurity failures by the Account or any of its service providers, or the issuers of any portfolio securities in which the Account invests (e.g., issuers of REIT stocks or debt securities), have the ability to result in disruptions to and impacts on business operations and may adversely affect the Account and the value of your accumulation units. Such disruptions or impacts may result in: financial losses; interference with the processing of contract transactions, including the processing of orders from TIAA’s website; interfere with the Account’s ability to calculate AUVs; barriers to trading and order processing; Account contract owners’ inability to transact business with the Account; violations of applicable federal and state privacy or other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. The Account may incur additional, incremental costs to prevent and mitigate the risks of cybersecurity attacks or incidents in the future. The Account and its contract owners could be negatively impacted by such cyber-attacks or incidents. Although the Account has established business continuity plans and risk-based processes and controls to address such cybersecurity risks, there are inherent limitations in such plans and systems in part due to the evolving nature of technology and cybersecurity attack tactics. As a result, it is possible that the Account or the Account’s service providers will not be able to adequately identify or prepare for all cybersecurity attacks. In addition, the Account cannot directly control the cybersecurity plans or systems implemented by its service providers.

About the Account’s investments — In general

Direct investments in real estate

Direct Purchase: The Account will generally buy direct ownership interests in existing or newly constructed income-producing properties, primarily office, industrial, retail, and multi-family residential properties, and, to a lesser extent, the Account will selectively buy student housing properties. The Account will invest mainly in established properties with existing rent and expense schedules or in newly constructed properties with predictable cash flows or, in very limited cases, where a seller agrees to provide certain minimum income levels. In addition, the Account will selectively invest in real estate development projects or engage in redevelopment projects, including pure ‘ground up’ developments. The Account does not directly invest in single-family residential real estate, nor does it currently invest in residential mortgage-backed securities (“RMBS”), although it may invest in such securities in the future.

Purchase-Leaseback Transactions: Although it has not yet done so, the Account can enter into purchase-leaseback transactions (leasebacks) in which it would buy land and income-producing improvements on the land (such as buildings), and simultaneously lease the land and improvements to a third party (the lessee). Leasebacks are generally for very long terms. Usually, the lessee is responsible for operating the property and paying all operating costs, including taxes and mortgage debt. The Account can also give the lessee an option to buy the land and improvements.

In some leasebacks, the Account may purchase only the land under an income-producing building and lease the land to the building owner. In those cases, the Account could seek to share (or “participate”) in any increase in property value from building improvements or in the lessee’s revenues from the building above a base amount. The Account can invest in leasebacks that are subordinated to other interests in the land, buildings, and improvements ( e.g.,  first mortgages); in that case, the leaseback interest would be subject to greater risks.

Investments in mortgages

General: The Account can originate or acquire interests in mortgage loans, generally on the same types of properties it might otherwise buy — i.e., the Account will be a creditor. These mortgage loans may pay fixed or variable interest rates or have “participating” features (as described below). Normally the Account’s mortgage loans will be secured by properties that have income-producing potential. They usually will not be insured or guaranteed by the U.S. government, its agencies or anyone else. They usually will be non-recourse, which means they won’t be the borrower’s personal obligations. Most will be first mortgage loans on existing income-producing property, with first-priority liens on the property. These loans may be amortized ( i.e., principal is paid over the course of the loan), or may provide for interest-only payments, with a balloon payment at maturity. In addition, the Account may originate a mortgage loan on a property it has recently sold (this is sometimes called “seller financing”).

Participating Mortgage Loans: The Account may make mortgage loans which permit the Account to share (have a “participation”) in the income from or appreciation of the underlying property. These participations let the Account receive additional interest, usually calculated as a percentage of the income the borrower receives from operating, selling or refinancing the property. The Account may also have an option to buy an interest in the property securing the participating loan.

Managing Mortgage Loan Investments: TIAA can manage the Account’s mortgage loans in a variety of ways, including:

Other real estate-related investments

Joint Investment Vehicles Involved in Real Estate Activities: The Account can hold interests in joint ventures, limited partnerships, limited liability companies, funds, and other commingled investment vehicles involved in real estate-related activities, including owning, financing, managing, or developing real estate. Many times, the Account will have limited voting and management rights in these commingled vehicles, including over the selection and disposition of the underlying real estate-related assets owned by the vehicle. Also, the Account’s ability to sell freely its interests in commingled vehicles may be restricted by the terms of the governing agreements. From time to time, the Account may also serve as the general partner, managing member, manager or administrator for a joint venture, for which it may earn fees and assume certain responsibilities typically associated with serving as a manager. The Account will not hold real property jointly with TIAA or its affiliates.

Real Estate Investment Trusts: The Account may invest in public and/or privately placed registered and unregistered equity investments in REITs, which are entities (usually publicly owned and traded) that lease, manage, acquire, hold mortgages on, and develop real estate. Normally the Account will attempt to replicate the holdings of widely recognized REIT indexes, but at times may gain exposure to REITs by purchasing the common or preferred stock of an individual REIT, by purchasing index funds or exchange traded funds, or by purchasing debt securities issued by a REIT. REITs seek to maximize share value and increase cash flows by acquiring and developing new real estate projects, upgrading existing properties or renegotiating existing arrangements to increase rental rates and occupancy levels. REITs must distribute at least 90% of their taxable income to shareholders in order to benefit from a special tax structure, which means they may pay high dividends. The value of a particular REIT can be affected by such factors as general economic and market conditions (in particular as to publicly traded REITs), the performance of the real estate sector in which the REIT primarily invests, cash flow, the skill of its management team, and defaults by its lessees or borrowers.

Mortgage-Backed Securities: The Account can invest in mortgage-backed securities and other mortgage-related or asset-backed instruments, including CMBS, RMBS, mortgage-backed securities issued or guaranteed by agencies or instrumentalities of the U.S. government, non-agency mortgage instruments, and collateralized mortgage obligations that are fully collateralized by a portfolio of mortgages or mortgage-related securities. Mortgage-backed securities are instruments that directly or indirectly represent a participation in, or are secured by and payable from, one or more mortgage loans secured by real estate. In most cases, mortgage-backed securities distribute principal and interest payments on the mortgages to investors. Interest rates on these instruments can be fixed or variable. Some classes of mortgage-backed securities may be entitled to receive mortgage prepayments before other classes do. Therefore, the prepayment risk for a particular instrument may be different than for other mortgage-related securities. Many classes of mortgage-backed securities experienced volatility in pricing and liquidity following the 2008 financial crisis with some volatility persisting to the present day.

Mezzanine Loan Investments: Consistent with its investment objectives, the Account may consider investments in mezzanine debt. Management believes that mezzanine lending may provide opportunities to generate returns that are commensurate with targeted returns for property acquisitions. Unlike a commercial mortgage loan, a mezzanine loan is not secured by a mortgage on a property. Rather, it is a debt investment whereby the lender typically has a security interest in an owner’s equity in an entity that owns a property. A mezzanine loan is subordinate to a first mortgage but senior to the owner’s ownership interest. If a borrower fails to make an interest payment, a mezzanine lender can foreclose on the equity of the entity that owns the property. For higher quality assets, management will selectively determine whether to enter into mezzanine loan investments with higher levels of leverage.

Stock of Companies Involved in Real Estate Activities: From time to time, the Account can invest in common or preferred stock of companies whose business involves real estate. These stocks may be listed on U.S. or foreign stock exchanges or traded over-the-counter in the U.S. or abroad.

Non-real estate-related investments

The Account can also invest in:

Foreign real estate and other foreign investments

The Account from time to time will invest in foreign real estate or real estate-related investments. It might also invest in securities or other instruments of foreign government or private issuers. Under the Account’s investment guidelines, investments in direct foreign real estate, together with foreign real estate-related securities and foreign non-real estate-related liquid investments, may not comprise more than 25% of the Account’s net assets. However, through the date of this prospectus, such foreign real estate-related investments have never represented more than 7.5% of the Account’s net assets and management does not intend such foreign investments to exceed 10% of the Account’s net assets. As of the date of this prospectus, the Account did not hold any foreign real estate investments.

Depending on investment opportunities, the Account’s foreign investments could at times be concentrated in one or two foreign countries. We will consider the special risks involved in foreign investing before investing in foreign real estate and won’t invest unless our standards are met.

General investment and operating policies

Standards for real estate investments

Buying Real Estate or Making Mortgage Loans: Before the Account purchases real estate or makes a mortgage loan, TIAA will consider such factors as:

TIAA will also analyze the fair market value of the underlying real estate, taking into account the property’s operating cash flow (based on the historical and projected levels of rental and occupancy rates and expenses), as well as the general economic conditions in the area where the property is located.

Diversification: We haven’t placed percentage limitations on the type and location of properties that the Account can buy. However, the Account seeks to diversify its investments by type of property, geographic location and tenant mix. How much the Account diversifies will depend upon whether suitable investments are available, the Account’s ability to divest of properties that are in over-concentrated locations or sectors, and how much the Account has available to invest.

Special Criteria for Making Mortgage Loans: Ordinarily, the Account will only make a mortgage loan if the loan, when added to any existing debt, will not exceed 85% of the appraised value of the mortgaged property when the loan is made, unless the Account is compensated for taking additional risk.

Selling Real Estate Investments: The Account doesn’t intend to buy and sell its real estate investments simply to make short-term profits, although proceeds from sales of real estate investments do play a role in the Account’s cash management generally. Rather, the Account’s general strategy in selling real estate investments is to dispose of those assets which management believes:

Management from time to time will evaluate the need to manage liquidity in the Account as part of its analysis as to whether to undertake a particular asset sale. The Account will reinvest any sale proceeds that management doesn’t believe it will need to pay operating expenses, fund other obligations (such as debt obligations and funding commitments under limited partnership agreements) or to meet participant redemption requests ( e.g., cash withdrawals or transfers).

Other real estate-related policies

Appraisals and Valuations of Real Estate Assets: The Account will rely on TIAA’s own analysis, normally along with an independent external appraisal, in connection with the purchase of a property by the Account. The Account will normally receive an independent external appraisal performed by a third-party appraisal firm at or before the time it buys a real estate asset, and the Account also generally obtains an independent appraisal when it makes mortgage loans.

Subsequently, each of the Account’s real properties are appraised, and mortgage loans are valued, at least once every calendar quarter. Each of the Account’s real estate properties are appraised each quarter by an independent third-party appraiser who is a member of a professional appraisal organization. In addition, TIAA’s internal appraisal staff performs a review of each independent appraisal of each real estate property as the final step in the Account’s process of determining the value, in conjunction with the Account’s independent fiduciary, and TIAA’s internal appraisal staff or the independent fiduciary may request an additional appraisal or valuation outside of this quarterly cycle. Any differences in the conclusions of TIAA’s internal appraisal staff and the independent appraiser will be reviewed by the independent fiduciary, which will make a final determination on the matter (which may include ordering a subsequent independent appraisal).

Please see the section below entitled “Valuing the Account’s assets” for more information on how each class of the Account’s investments (including assets other than real estate properties) are valued.

Borrowing: The Account is authorized to borrow money and assume or obtain a mortgage on a property — i.e., make leveraged real estate investments. Under the Account’s current investment guidelines, management intends to maintain the Account’s loan to value ratio at or below 30% (measured at the time of incurrence and after giving effect thereto). Forms of borrowing may include:

The Account’s loan to value ratio at any time is based on the ratio of the outstanding principal amount of the Account’s debt to the Account’s total gross asset value. The Account’s total gross asset value, for these purposes, is equal to the total fair value of the Account’s assets (including the fair value of the Account’s interest in joint ventures), with no reduction associated with any indebtedness on such assets.

In calculating outstanding indebtedness, we will include only the Account’s actual percentage interest in any borrowings on a joint venture investment and not that of any joint venture partner. Also, at the time the Account (or a joint venture in which the Account is a partner) enters into a revolving line of credit, management deems the maximum amount which may be drawn under that line of credit as fully incurred, regardless of whether the maximum amount available has been drawn from time to time.

As of December 31, 2016 , the aggregate principal amount of the Account’s outstanding debt (including the Account’s share of debt on its joint venture investments) was approximately $4.4 billion and the Account’s loan to value ratio was approximately 15.0% .

In times of high net inflow activity, in particular during times of high net participant transfer inflows, management may determine to apply a portion of such cash flows to make prepayments of indebtedness prior to scheduled maturity, which would have the effect of reducing the Account’s loan to value ratio. Such prepayments may require the Account to pay fees or ‘yield maintenance’ amounts to lenders.

The Account may only borrow up to 70% of the then current value of a property, although construction loans may be for 100% of costs incurred in developing a property. Except for construction loans, any mortgage loans on a property will be non-recourse to the Account, meaning that if there is a default on a loan in respect of a specific property, the lender will have recourse to ( i.e., be able to foreclose on) only the property encumbered (or the joint

venture owning the property), or to other specific Account properties that may have been pledged as security for the defaulted loan, but not to any other assets of the Account. When possible, the Account will seek to have loans mature at varying times to limit the risks of borrowing.

The Account will not obtain mortgage financing on properties it owns from TIAA or any of its affiliates. Under certain circumstances, TIAA or an affiliate may provide a loan to a third party purchaser of a property sold by the Account, but no such financing will be made with respect to a property the Account still owns. However, the Account may place an intra-company mortgage on an Account property held by a subsidiary for tax planning or other purposes. This type of mortgage will not be subject to the general limitations on borrowing described above.

When the Account assumes or obtains a mortgage on a property, it will bear the expense of mortgage payments. It will also be exposed to certain additional risks, which are described in the section above entitled “Risk factors — Risks of borrowing.”

In addition, while it has not done so through the date of this prospectus, the Account may obtain a line of credit to meet short-term cash needs, which line of credit may be unsecured and/or contain terms that may require the Account to secure a loan with one or more of its properties. Management expects the proceeds from any such short-term borrowing would be used to meet the cash flow needs of the Account’s properties and real estate-related investments, but depending on the circumstances, proceeds could be used for Account-level funding needs (including the need to honor unexpected participant withdrawal activity).

Discretion to Evict or Foreclose: TIAA may, in its discretion, evict defaulting tenants or foreclose on defaulting borrowers to maintain the value of an investment, when it decides that it is in the Account’s best interests.

Property Management and Leasing Services: The Account usually will hire a national or regional independent third-party property management company to perform the day-to-day management services for each of the Account’s properties, including supervising any on-site personnel, negotiating maintenance and service contracts, providing advice on major repairs and capital improvements and assisting the Account in ensuring compliance with environmental regulations. The property manager will also recommend changes in rent schedules and create marketing and advertising programs to attain and maintain high levels of occupancy by responsible tenants. The Account may also hire independent third-party leasing companies to perform or coordinate leasing and marketing services to fill any vacancies. The fees paid to the property management company, along with any leasing commissions and expenses, will reduce the Account’s cash flow from a property.

Insurance: We intend to arrange for, or require proof of, comprehensive insurance, including liability, fire, and extended coverage, for the Account’s real properties and properties securing mortgage loans or subject to purchase-leaseback transactions. The Account currently participates in property, casualty and other related insurance programs as part of TIAA’s property insurance programs, and the Account bears only the cost of insuring only the properties it owns. The terms and conditions of the insurance coverage the Account has on its properties, in conjunction with the type of loss actually suffered at a property, may subject the property, or the Account as a whole, to a cap on insurance proceeds that is less than the loss or losses suffered. In addition, the Account’s insurance policies on its properties currently include catastrophic coverage for wind, earthquakes and terrorist acts, but we can’t assure you that it will be adequate to cover all losses. We also can’t assure you that we will be able to obtain coverage for wind, earthquakes and terrorist acts at an acceptable cost, if at all, at the time a policy expires. While the Account will seek to have coverage placed with highly rated, financially healthy insurance carriers, the Account is reliant on the continued financial health of the third-party insurers it engages.

Other policies

Investment Company Act of 1940: The Account has not registered, and we intend to operate the Account so that it will not have to register, as an “investment company” under the Investment Company Act. This will require monitoring the Account’s portfolio so that it won’t have more than 40% of the value of its total assets, excluding U.S. government securities and cash items, in investment securities. As a result, the Account may be unable to make some potentially profitable investments, it may be unable to sell assets it would otherwise want to sell or it may be forced to sell investments in investment securities before it would otherwise want to do so.

Changing Operating Policies or Winding Down: Under the terms of the contracts and in accordance with applicable insurance law, TIAA can decide, in its sole discretion, to change the operating policies of the Account or to wind it down. If the Account is wound down, you may need to transfer your accumulations or annuity income to TIAA’s Traditional Annuity or any CREF account available under your employer’s plan. All investors in the Account will be notified in advance if we decide to change a significant policy or wind down the Account.

Securities Lending: Subject to the Account’s investment policies relating to loans of portfolio securities, the Account may lend certain of its portfolio securities (e.g., REIT stocks) to certain other financial institutions, including brokers and dealers that are not affiliated with the Account or TIAA, are registered with the SEC and are members of the Financial Industry Regulatory Authority (“FINRA”). All loans of the Account’s portfolio securities will be fully collateralized. In connection with the lending of its securities, the Account will receive as collateral cash, securities issued or guaranteed by the U.S. Government (e.g., Treasury securities), or other collateral permitted by applicable law, which at all times while the loan is outstanding will be maintained in amounts equal to at least 100% of the current market value of the outstanding loaned securities for U.S. equities (including domestic REIT stocks) and fixed-income assets and 105% for non-U.S equities (including foreign REIT stocks), or such lesser percentage as may be permitted by the SEC or the NY Department of Financial Services (“NYDFS”) (including a decline in the value of the collateral). Such percentage may not fall below 100% of the market value of the loaned securities (unless due to a decline in the value of the collateral), and all such collateral levels will be reviewed daily.

Cash collateral received by the Account will generally be invested in overnight cash deposits, U.S. Treasury repurchase agreements (or repos), or in one or more funds maintained by the Account’s securities lending agent for the purpose of investing cash collateral. During the term of the loan, the Account will continue to have investment risks with respect to the securities being loaned, as well as risk with respect to the investment of the cash collateral, and the Account may lose money as a result of the investment of such collateral. In addition, an Account could suffer loss if the loan terminates and the Account is forced to liquidate investments at a loss in order to return the cash collateral to the borrower.

By lending its securities, the Account will receive amounts equal to the interest or dividends paid on the securities loaned and, in addition, will expect to receive a portion of the income generated by the short-term investment of cash received as collateral or, alternatively, where securities or letter of credit are used as collateral, a lending fee paid directly to the Account by the borrower of the securities. Under certain circumstances, a portion of the lending fee may be paid or rebated to the borrower by the Account. Such securities loans will be terminable by the Account at any time and will not be made to affiliates of TIAA. The Account may terminate a loan of securities in order to regain record ownership of, and to exercise beneficial rights related to, the loaned securities, including, but not necessarily limited to, voting or subscription rights. The Account may also terminate a loan in the event that a vote of holders of those securities is required on a material matter. The Account may pay reasonable fees to persons unaffiliated with the Account for services, for arranging such loans, or for acting as securities lending agent (each an “Agent”). Loans of securities will be made only to firms deemed creditworthy.

Establishing and managing the Account — The role of TIAA

Establishing the Account

The Board established the Real Estate Account as a separate account of TIAA under New York law on February 22, 1995. The Account is regulated by the New York State Department of Financial Services (“NYDFS”) and the insurance departments of the other jurisdictions in which the annuity contracts are offered. Although TIAA owns the assets of the Real Estate Account, and the Account’s obligations under the contracts are obligations of TIAA, the Account’s income, investment gains, and investment losses are credited to or charged against the assets of the Account without regard to TIAA’s other income, gains, or losses. Under New York insurance law, we can’t charge the Account with liabilities incurred by any other TIAA business activities or any other TIAA separate account.

Managing the Account

TIAA employees, under the direction and control of the Board, manage the investment of the Account’s assets, following investment management procedures TIAA has adopted for the Account. The Account does not have officers, directors or employees. TIAA’s investment management responsibilities include:

In addition, TIAA performs administration functions for the Account. These functions include receiving and allocating premiums, calculating and making annuity payments and providing recordkeeping and other services. Distribution services for the Account (which include, without limitation, distribution of the annuity contracts, advising existing annuity contract owners in connection with their accumulations and helping employers implement and manage retirement plans) are performed by Services. TIAA and Services provide investment management, administration and distribution services, as applicable, on an “at-cost” basis. In the future, TIAA may retain one or more affiliated sub-advisers (e.g., one or more registered investment advisers in TIAA’s Nuveen division) to provide investment management and administration services to the Account. For more information about the charge for investment management, administration and distribution services, please see the section below entitled “Expense deductions.”

You don’t have the right to vote for TIAA Trustees. Please see the section below entitled “General matters — Voting rights.” For information about the Trustees, certain executive officers of TIAA and the Account’s portfolio management team, see Appendix A of this prospectus.

TIAA’s ERISA Fiduciary Status. To the extent that assets of a plan subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), are allocated to the Account, TIAA will be acting as an “investment manager” and a fiduciary under ERISA with respect to those assets.

Liquidity guarantee

The TIAA General Account provides the Account with a liquidity guarantee enabling the Account to have funds available to meet participant redemption, transfer or cash withdrawal requests. This guarantee is required by the NYDFS. If the Account can’t fund participant requests from the Account’s own cash flow and liquid investments, the TIAA General Account will fund such requests by purchasing accumulation units (accumulation units that are purchased by TIAA are generally referred to as “liquidity units”) issued by the Account. TIAA guarantees that you can redeem your accumulation units at their accumulation unit value next determined after your transfer or cash withdrawal request is received in good order. “Good order” means actual receipt of the transaction request along with all information and supporting legal documentation necessary to effect the transaction. Whether the liquidity guarantee is exercised is based on the cash level of the Account from time to time, as well as recent participant withdrawal activity and the Account’s expected working capital, debt service and cash needs, all subject to the oversight of the independent fiduciary. While the proceeds from liquidity unit purchases are not placed in a segregated account solely to fund participant requests, the guarantee is in place to meet participant needs. Liquidity units owned by TIAA are valued in the same manner as accumulation units owned by the Account’s participants. Importantly, however, this liquidity guarantee is not a guarantee of the investment performance of the Account or a guarantee of the value of your units. Transfers from the Account to a CREF or TIAA account, or another investment option, are limited to once every calendar quarter (except for specifically prescribed systematic transfers established in accordance with the terms of the participant’s contract and employer’s plan), and cash withdrawals may be further restricted by the terms of your plan.

TIAA’s obligation to provide Account participants liquidity through purchases of liquidity units is not subject to an express regulatory or contractual limitation, although as described under the section below entitled “Establishing and managing the Account — the role of TIAA — Role of the independent fiduciary,” the independent fiduciary may (but is not obligated to) require the reduction of TIAA’s interest through sales of assets from the Account if TIAA’s interest exceeds a predetermined trigger point. Even if this trigger point were reached and regardless of whether the independent fiduciary has required the Account to dispose of any assets, TIAA’s obligation to provide liquidity under the guarantee will continue.

Please see the section below entitled “Expense deductions.” Primarily as a result of significant net participant transfers throughout 2008 (in particular, in the second half of 2008), pursuant to this liquidity guarantee obligation, the TIAA General Account first purchased liquidity units on December 24, 2008. Between December 2008 and June 2009, the TIAA General Account paid an aggregate of approximately $1.2 billion to purchase liquidity units in a number of separate transactions, with the last such transaction occurring in June 2009. Management cannot predict whether future liquidity unit purchases will be required under the liquidity guarantee although as of the date of this prospectus, management believes such purchases are unlikely in the near term.

Redemption of Liquidity Units. The independent fiduciary is vested with oversight and approval over any redemption of TIAA’s liquidity units, acting in the best interests of the Account’s participants.

As of December 31, 2016 , TIAA did not own any liquidity units, as the independent fiduciary completed the systematic redemption of all of the liquidity units previously held by the TIAA General Account in March 2013. As a

general matter, the independent fiduciary may authorize or direct the redemption of all or a portion of liquidity units at any time and TIAA will request the approval of the independent fiduciary before any liquidity units are redeemed.

Upon termination and liquidation of the Account (wind-up), any liquidity units held by TIAA will be the last units redeemed, unless the independent fiduciary directs otherwise. Finally, TIAA may redeem its liquidity units more frequently than once per calendar quarter, subject at all times to the oversight and approval of the Account’s independent fiduciary (discussed in more detail in the subsection entitled “— Role of the independent fiduciary” immediately below).

Role of the independent fiduciary

Because TIAA’s ability to purchase and sell liquidity units raises certain technical issues under ERISA, TIAA applied for and received a prohibited transaction exemption from the U.S. Department of Labor in 1996 (PTE-96-76). In connection with the exemption, TIAA has appointed an independent fiduciary for the Real Estate Account, with overall responsibility for reviewing Account transactions to determine whether they are in accordance with the Account’s investment guidelines. RERC, LLC, a real estate consulting firm whose principal offices are located in Des Moines, IA (“RERC”), was appointed as independent fiduciary effective March 1, 2006 and currently serves as the Account’s independent fiduciary pursuant to an amended and restated letter agreement effective March 1, 2015, whose term expires on February 28, 2018.

Under the terms of PTE 96-76, RERC’s responsibilities include:

In addition, RERC has certain responsibilities with respect to the Account that it had historically undertaken or is currently undertaking with respect to TIAA’s purchase and ownership of liquidity units, including among other things, reviewing the purchases and redemption of liquidity units by TIAA to ensure the Account uses the correct unit values. In connection therewith, as set forth in PTE 96-76, the independent fiduciary’s responsibilities include:

In establishing the appropriate trigger point, including whether or not to require certain actions once the trigger point has been reached, the independent fiduciary will assess, among other things and to the extent consistent with PTE 96-76 and the independent fiduciary’s duties under ERISA, the risk that a conflict of interest could arise due to the level of TIAA’s ownership interest in the Account.

A special subcommittee consisting of five (5) independent outside members of the Investment Committee of the Board renewed the appointment of RERC as the independent fiduciary for an additional three-year term, which appointment was effective as of March 1, 2015, and continues through February 28, 2018. This subcommittee may renew the independent fiduciary appointment, remove the independent fiduciary, or appoint its successor. The independent fiduciary can be removed for cause by the vote of three (3) out of the five (5) subcommittee members and will not be reappointed if two (2) of the subcommittee members disapprove of the reappointment. The independent fiduciary can resign after providing at least 180 days’ written notice.

The Account pays the independent fiduciary directly. The investment management charge includes the costs associated with retaining the independent fiduciary. Under PTE 96-76, the independent fiduciary must receive less than 5% of its annual gross revenues (including payment for its services to the Account) from TIAA and its affiliates.

When you decide as a participant or plan fiduciary to invest in the Account, after TIAA has provided you with full and fair disclosure, including the disclosure in this prospectus, you are also acknowledging that you approve and accept RERC or any successor to serve as the Account’s independent fiduciary.

Conflicts of interest

General. Employees of TIAA that provide advice with respect to the Real Estate Account may also provide investment advice with respect to investments owned by TIAA, and investments managed by TIAA-CREF Alternatives Advisors, LLC (“TCAA”) and Teachers Advisors, LLC ("TA"), both indirect, wholly owned subsidiaries of TIAA and registered investment advisers. In addition, TIAA and its affiliates offer (and may in the future offer) other accounts and investment products that are not managed under an “at cost” expense structure. Therefore, TIAA and its employees may at times face various conflicts of interest. For example, the TIAA General Account and a privately offered core property investment fund managed by TCAA (the “core property investment fund”) may sometimes compete with the Account in the purchase of investments; however, both accounts will be subject to the allocation procedure described below. (Each of the TIAA General Account, the Account and the core property investment fund together with any other real estate accounts or funds that are established or may be established by TIAA or its affiliates in the future, are herein referred to as an “account.”)

Many of the personnel of TIAA involved in performing services to the Account will have competing demands on their time. The personnel will devote such time to the affairs of the Account as TIAA’s management determines, in its sole discretion exercising good faith, is necessary to properly service the Account. TIAA believes that it has sufficient personnel to discharge its responsibility to the Account, the General Account, the core property investment fund and other accounts to avoid conflicts of interest. TIAA or its affiliates may form and/or manage other real estate investment vehicles in the future and we will take steps to assure that those vehicles are integrated into appropriate conflict of interest policies. TIAA does not accept acquisition or placement fees for the services it provides to the Account.

Allocation Procedure. TIAA and its affiliates (including THRE and other subsidiaries of Nuveen, LLC) allocate new investments (including real property investments and commercial mortgages, but generally not real estate limited partnership investments) among the accounts (including the Account) in accordance with a written allocation procedure as adopted by TIAA and such affiliates and modified from time to time. Under the allocation procedure, an internal real estate acquisitions team adds transactions as they are identified into an internal deal pipeline. Proposed transactions in the pipeline are presented at regular internal real estate review meetings, at which the portfolio managers for each of the accounts will evaluate acquisition opportunities which conform to the investment strategy of the applicable account. If only one portfolio manager is interested in making a bid to pursue the transaction, the transaction is allocated to that account and there is no change in the rotation order. However, if more than one account expresses an interest in a transaction in a particular sector, a strict rotation system will be used so that the accounts are treated equitably and transactions are impartially allocated.

Under the rotation system, an allocations coordinator will allocate a transaction to the interested account in the top most position of the rotation for a specific real estate sector, but the Account will then drop to the bottom of the rotation for new or additional investment opportunities in that sector. This rotation system is employed on a sector-by-sector basis for each of the office, retail, industrial, multi-family, student housing and other sectors; and each sector has its own rotation. As a result, an account (including the Account) could, at any one time, be at the top or

the bottom of the rotation for new investment opportunities in any one or all five of the sectors in which the Account could invest. If an account chooses not to pursue a transaction that has been allocated to it, the acquisitions team may bring the transaction back into the main rotation. New funds or accounts with the ability to invest in transactions without a co-investor (i.e., “stand alone” accounts), will be added to the main rotation. Where such new funds or accounts are a co-investor with TIAA as a joint venture partner and the portfolio manager for TIAA or THRE affiliate does not have discretion to deploy investors’ capital for acquisitions within such mandate (i.e., a non-discretionary mandate) , such mandates will be part of a sub-rotation within the account that was allocated the transaction and will not have a separate place in the main rotation. New funds or accounts where TIAA is a joint venture partner and the portfolio manager for TIAA or THRE affiliate does have discretion to deploy investors’ capital for acquisitions within such mandate (i.e., a fully discretionary mandate), regardless of the ownership percentage, are added to the main rotation.

Also, there may be circumstances where multiple properties are presented to TIAA for sale as a single acquisition opportunity, and the proposed price is inclusive of all the properties. If more than one account has interest in all or a portion of such bundled acquisition opportunity, the acquisitions team will investigate with the seller whether the properties can be unbundled and offered to the accounts on an individual basis and the sector-based rotation system described above will apply to the allocation of such unbundled properties.

The allocation procedure contains substantive requirements for proceeding through the different stages of the bidding process prior to allocation to preserve the fairness, equitability and transparency of the transaction. The procedure also provides a process for handling exceptions to the allocation process when requested by a portfolio manager for the accounts.

The allocation procedure is overseen and monitored by senior officers of TIAA and its affiliates, including THRE and other subsidiaries of Nuveen, LLC ("Nuveen"), pursuant to Nuveen's existing compliance policies and processes.

Leasing Conflicts. Conflicts could also arise because some properties in the TIAA General Account, the core property investment fund and other accounts may compete for tenants with the Account’s properties. Management believes the potential for leasing conflicts are minimized by the unique characteristics of each property, including location, submarket, physical characteristics, amenities and lease rollover schedules. Management believes the differing business strategies of the accounts also reduce potential conflicts. If a conflict arises, as appropriate, the competing accounts will arrange that different property managers and leasing brokers are engaged, each charged with using their best efforts to support the property management and leasing activity for each particular property and an ethical screen will be placed between the internal asset managers for the respective properties.

Sales Conflicts. Conflicts could also potentially arise when two TIAA accounts attempt to sell properties located in the same market or submarket, especially if there are a limited number of potential purchasers and/or if such purchaser has an ongoing business relationship with TIAA or one of its specific accounts.

Liquidity Guarantee. TIAA’s ownership of liquidity units (including potential changes in future ownership levels) could result in the perception that TIAA is taking into account its own economic interests while serving as investment manager for the Account. In particular, there is the concern that TIAA could make investment decisions (and other management decisions) with respect to the Account which serves the interest of the TIAA General Account, at the expense of those participants that have chosen the Account as an investment option. This could manifest itself, among other ways, by the Account disposing its properties solely to raise liquidity in avoidance of having a need for the liquidity guarantee, or by foregoing otherwise attractive investment opportunities so as not to impair liquid asset levels.

Management believes that any conflict (or potential conflict) is mitigated by, among other things, the detailed valuation procedure for the Account’s properties, which includes independent appraisals and the oversight of the independent fiduciary. Also, the independent fiduciary oversees the execution of the liquidity guarantee to ensure the proper unit values are applied, and the independent fiduciary will oversee any liquidity unit redemptions. Further, the independent fiduciary is vested with the right to establish a trigger point, which is a level of ownership at which the fiduciary is empowered, but not required, to reduce TIAA’s ownership interest (with the goal to mitigate any potential conflict of interest) through the means described in the immediately preceding section. For example, the independent fiduciary could perceive a conflict of interest if it believed that management directed the sale of properties solely to increase liquidity (not in accordance with the Account’s investment guidelines or at “fire sale” prices) with the sole goal of avoiding the need for further TIAA liquidity unit purchases under the liquidity guarantee. In such case, the independent fiduciary would be authorized to adjust the trigger point, at which time the fiduciary would have control over the sales of properties (including the timing and pricing) to ensure such sales are in the best interests of the Account.

While it retains the oversight over the Account’s investment guidelines, valuation and appraisal matters and the liquidity guarantee as described in “— Role of the independent fiduciary,” the independent fiduciary’s authority to override investment management decisions made by TIAA’s managers acting on behalf of the Account is limited to those circumstances after which the trigger point has been reached or during a wind-down of the Account.

Indemnification

The Account has agreed to indemnify TIAA and its affiliates, including its officers and trustees, against certain liabilities to the extent permitted by law, including liabilities under the Securities Act of 1933. The Account may make such indemnification out of its assets. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to TIAA and its affiliates, the Account has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.

Summary of the Account’s properties

The properties — In general

At December 31, 2016 , the Account owned a total of 129 real estate investments ( 105 of which were wholly owned and 24 of which were held in real estate-related joint ventures), representing 79.1% of the Account’s total investment portfolio (on a gross asset value basis). At December 31, 2016 , the real estate portfolio included:

Of the 129 real estate investments, 33 were subject to mortgages (including 13 joint venture property investments).

Additional detailed information regarding the Account’s properties, including its commercial (non-residential) and residential property investments, as well as the Account’s ten largest tenants, as of December 31, 2016 can be found in the Account’s 2016 Form 10-K and is incorporated by reference in this prospectus. The Account’s investments include both properties that are wholly owned by the Account and properties owned by the Account’s joint venture investments. Certain property investments are comprised of a portfolio of properties.

Recent transactions

The following describes property and financing transactions by the Account since February 23, 2017, the date of the Account’s most recent prospectus supplement (comprising a part of Registration Statement No. 333-210139). Except as noted, the expenses for operating the properties purchased are either borne or reimbursed, in whole or in part, by the property tenants, although the terms vary under each lease. The Account is responsible for operating expenses not reimbursed under the terms of a lease.

Purchases

Matsil Building - Long Island City, NY

On March 8, 2017, the Account purchased a 97.5% interest in a joint venture investment, which holds an industrial property located in Long Island City, New York. The Account purchased its interest for $54.3 million.

Financings

DDR Joint Venture - Various, USA

On March 1, 2017, the Account’s DDR joint venture investment, in which the Account holds an 85% interest, extinguished $80.7 million of outstanding mortgage debt (the Account's share) secured by two retail properties.

Valuing the Account’s assets

We value the Account’s assets as of the close of each valuation day by taking the sum of:

and then reducing the sum by the Account’s liabilities, including the daily investment management, administration and distribution fees and certain other fees and expenses attributable to operating the Account. Daily estimates of net operating income are adjusted to reflect actual net operating income on a monthly basis, at which time such adjustments (if any) are reflected in the Account’s unit value. Please see the section below entitled “Expense deductions.”

Fair value for the Account’s assets is based upon quoted market prices in active exchange markets, where available. If listed prices or quotes in such markets are not available, fair value is based upon vendor-provided, evaluated prices or internally developed models that primarily use market-based or independently sourced market data, including interest rate yield curves, market spreads, and currency rates. Valuation adjustments may be made to reflect credit quality, a counterparty’s creditworthiness, the Account’s creditworthiness, liquidity, and other observable and unobservable data that are applied consistently over time.

The methods described earlier are considered to produce a fair value calculation that represents a good faith estimate as to what an unaffiliated buyer in the market place would pay to purchase the asset or receive to transfer the liability. Since fair value calculations involve significant professional judgment in the application of both observable and unobservable attributes, actual realizable values or future fair values may differ from amounts reported. Furthermore, while the Account believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments, while reasonable, could result in different estimates of fair value at the reporting date.

Valuing real estate investments

Valuing Real Property: Investments in real estate properties are stated at fair value, as determined in accordance with policies and procedures reviewed by the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole. Accordingly, the Account does not record depreciation.

Fair value for real estate properties is defined as the price that would be received to sell the asset in an orderly transaction between market participants at the measurement date. Determination of fair value involves significant levels of judgment because the actual market value of real estate can be determined only by negotiation between the parties in a sales transaction. Property and investment values are affected by, among other things, the availability of capital, occupancy rates, rental rates, and interest and inflation rates. As a result, determining real estate and investment values involves many assumptions. Amounts ultimately realized from each investment may vary significantly from the market value presented. Actual results could differ from those estimates. Please see the section above entitled “Risk factors — Risks associated with real estate investing — Valuation and appraisal risks.”

In accordance with the Account’s procedures designed to comply with Fair Value Measurements and Disclosures in U.S. Generally Accepted Accounting Principles (“GAAP”), the Account values real estate properties purchased by the Account initially based on an independent appraisal at the time of the closing of the purchase, which may result in a potential unrealized gain or loss reflecting the difference between an investment’s fair value ( i.e., exit price) and its cost basis (which is inclusive of transaction costs).

Subsequently, each property will be valued each quarter by an independent appraiser and the property value will be updated as appropriate. In general, the Account obtains independent appraisals of its real estate properties spread out throughout the quarter, which is intended to result in appraisal adjustments, and thus, adjustments to the valuations of its holdings (to the extent such adjustments are made), that happen regularly throughout each quarter and not on one specific day in each quarter.

Further, management reserves the right to order an appraisal and/or conduct another valuation outside of the normal quarterly process when facts or circumstances at a specific property change (for example, under certain circumstances a valuation adjustment could be made when bids are obtained for properties held for sale). The Account’s independent fiduciary, RERC, LLC oversees the Account’s entire appraisal process and, among other things, must approve all independent appraisers used by the Account. TIAA’s internal appraisal staff oversees the entire appraisal process and reviews each independent quarterly appraisal, in conjunction with the Account’s independent fiduciary, prior to the value reflected in that appraisal being recorded in the Account. Any differences in the conclusions of TIAA’s internal appraisal staff and the independent appraiser will be reviewed by the independent fiduciary, which will make a final determination on the matter (which may include ordering a subsequent independent appraisal).

Real estate appraisals are estimates of property values based on a professional’s opinion. All appraisals are performed in accordance with Uniform Standards of Professional Appraisal Practices, the real estate appraisal industry standards created by The Appraisal Foundation. Appraisals of properties held outside of the U.S. are performed in accordance with industry standards commonly applied in the applicable jurisdiction. Further, these independent appraisers (as well as TIAA’s internal appraisal staff) are always expected to be MAI-designated members of the Appraisal Institute (or its European equivalent, Royal Institute of Chartered Surveyors) and state certified appraisers from national or regional firms with relevant property type experience and market knowledge. Under the Account’s current procedures, each independent appraisal firm will be rotated off of a particular property at least every three years, although such appraisal firm may perform appraisals of other Account properties subsequent to such rotation.

We intend that the overarching principle and primary objective when valuing our real estate investments will be to produce a valuation that represents a fair and accurate estimate of the fair value of our investments. Implicit in our definition of fair value is the consummation of a sale as of a specified date and the passing of title from seller to buyer under conditions whereby:

The Account’s net asset value will include the value of any note receivable (an amount that someone else owes the Account) from selling a real estate-related investment. We’ll estimate the value of the note by applying a discount rate appropriate to then-current market conditions.

Development Properties. Development properties will be carried at fair value, which is anticipated initially to equal the Account’s cost, and the value will be adjusted as additional development costs are incurred. At a minimum, once a property receives a certificate of occupancy, within one year from the initial funding by the Account, or the property is substantially leased, whichever is earlier, the property will be appraised by an independent external appraiser approved by the independent fiduciary. We may also have the properties independently appraised earlier if circumstances warrant.

Property Portfolios. The Account may, at times, value individual properties together (whether or not purchased at the same time) in a portfolio as a single asset, to the extent we believe that the property may be sold as one portfolio. The Account may also realize efficiencies in property management by pooling a number of properties into

a portfolio. The value assigned to the portfolio as a whole may be more or less than the valuation of each property individually. The Account will also, from time to time, sell one or more individual properties that comprise a portfolio, with the Account retaining title to the remaining individual properties comprising that portfolio. In such a circumstance, the Account could determine to no longer designate such remaining properties as one portfolio.

Because of the nature of real estate assets and because the fair value of our investments is not reduced by transaction costs that will be incurred to sell the investments, the Account’s net asset value won’t necessarily reflect the net realizable value of its real estate assets ( i.e., what the Account would receive if it sold them). Please see the section entitled “Valuing the Account’s assets — Valuation Adjustments.”

Valuing Real Property Subject to a Mortgage: When a real estate property is subject to a mortgage, the mortgage is valued independently of the property and its fair value is reported separately. The independent fiduciary reviews and approves all mortgage valuation adjustments before such adjustments are recorded by the Account. The Account will continue to use the revised value for each real estate property and mortgage loan payable to calculate the Account’s daily net asset value until the next valuation review or appraisal.

Valuing Loans Receivable ( i.e., the Account as a creditor): Loans receivable are stated at fair value and are initially valued at the face amount of the loan funding. Subsequently, loans receivable are valued at least quarterly based on market factors, such as market interest rates and spreads for comparable loans, the liquidity for loans of similar characteristics, the performance of the underlying collateral and the credit quality of the counterparty.

Valuing Mortgage Loans Payable ( i.e. , the Account as a debtor): Mortgage loans payable are stated at fair value. The estimated fair value of mortgage loans payable is generally based on the amount at which the liability could be transferred in a current transaction, exclusive of transaction costs. Fair values are estimated based on market factors, such as market interest rates and spreads on comparable loans, the liquidity for mortgage loans of similar characteristics, the performance of the underlying collateral (such as the loan-to-value ratio and the cash flow of the underlying collateral), the maturity date of the loan, the return demands of the market, and the credit quality of the Account. Different assumptions or changes in future market conditions could significantly affect estimated fair values. At times, the Account may assume debt in connection with the purchase of real estate.

Valuing Real Estate Joint Ventures: Real estate joint ventures are stated at the fair value of the Account’s ownership interests in the underlying entities. The Account’s ownership interests are valued based on the fair value of the underlying real estate, any related mortgage loans payable, and other factors, such as ownership percentage, ownership rights, buy/sell agreements, distribution provisions and capital call obligations. In addition, any restrictions on the right of the Account to transfer its ownership interest to third-parties could adversely affect the value of the Account’s interest. Upon the disposition of all real estate investments by an investee entity, the Account will continue to state its equity in the remaining net assets of the investee entity during the wind down period, if any, which occurs prior to the dissolution of the investee entity.

Valuing Real Estate Limited Partnerships: Limited partnerships are stated at the fair value of the Account’s ownership in the partnership, which is based on the most recent net asset value of the partnership, as reported by the sponsor. Since market quotations are not readily available, the limited partnership interests are valued at fair value as determined in good faith under the direction of the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole. As circumstances warrant, prior to the receipt of financial statements of the limited partnership, the Account will estimate the value of its interests in good faith and will from time to time seek input from the issuer or the sponsor of the investment vehicle.

Net Operating Income: The Account usually receives operating income from its investments intermittently, not daily. In fairness to participants, we estimate the Account’s net operating income rather than applying it when we actually receive it, and assume that the Account has earned (accrued) a proportionate amount of that estimated amount daily. You bear the risk that, until we adjust the estimates when we receive actual items of income, the Account’s net assets could be under- or over-valued.

Every year, we prepare a month-by-month estimate of the revenues and expenses (estimated net operating income) for each of the Account’s properties. Each day, we add the appropriate fraction of the estimated net operating income for the month to the Account’s net asset value.

Every month, the Account receives a report of the actual operating results for the prior month for each property (actual net operating income). We then recognize the actual net operating income on the accounting records of the Account and adjust the outstanding daily accrued receivable accordingly. As the Account actually receives income from a property, we’ll adjust the daily accrued receivable and other accounts appropriately.

Valuation Adjustments: General. Management reserves the right to order an appraisal and/or conduct another valuation outside of the normal quarterly process when facts or circumstances at a specific property change. Also, the independent fiduciary can require additional appraisals if it believes a property’s value may have changed materially and such change is not reflected in the quarterly valuation review, or otherwise to ensure that the Account is valued appropriately. For example, under certain circumstances a valuation adjustment could be made when bids are obtained for properties held for sale by the Account. In addition, adjustments may be made for events or circumstances indicating an impairment of a tenant’s ability to pay amounts due to the Account under a lease (including due to a bankruptcy filing of that tenant). Also, adjustments may be made to reflect factors (such as sales values for comparable properties or local employment rate) bearing uniquely on a particular region in which the Account holds properties. We may not always be aware of each event that might require a valuation adjustment, and because our evaluation is based on subjective factors and we give different weight to different factors, we may not in all cases make a valuation adjustment where changing conditions could potentially affect the value of an investment.

Required Approvals. The independent fiduciary will need to approve adjustments to any valuation of one or more properties or real estate-related assets that:

Right to Change Valuation Methods: If we decide that a different valuation method would reflect the value of a real estate-related investment more accurately, we may use that method if the independent fiduciary consents. Changes in TIAA’s valuation methods could change the Account’s net asset value and change the values at which participants purchase or redeem Account interests.

Valuing other investments (including certain real estate-related investments)

Debt Securities: We value debt securities (excluding money market instruments) for which market quotations are readily available based on the most recent bid price or the equivalent quoted yield for such securities (or those of comparable maturity, quality and type). We derive these values utilizing an independent pricing service, such as FT Interactive Data Corp, Reuters and Bloomberg, except when we believe the prices do not accurately reflect the security’s fair value. Debt securities for which market quotations are not readily available are valued at fair value as determined in good faith by the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole.

Short-term Investments: Short-term investments are valued in the same manner as debt securities stated in the preceding paragraph.

Money Market Instruments: We value money market instruments at amortized cost.

Equity Securities: We value equity securities (including REITs) listed or traded on the New York Stock Exchange (or any of its constituent, affiliate or subsidiary exchanges, including NYSE Arca) at their last sale price on the valuation day. If no sale is reported that day, we use the mean of the last bid and asked prices, exclusive of transaction costs. Equity securities listed or traded on any other exchange are valued in a comparable manner on the principal exchange where traded.

We value equity securities traded on the Nasdaq Stock Market at the Nasdaq Official Closing Price on the valuation day. If no sale is reported that day, we use the mean of the last bid and asked prices, exclusive of transaction costs. Other U.S. over-the-counter equity securities are valued at the mean of the last bid and asked prices.

Mortgage-Backed Securities: We value mortgage-backed securities, including CMBS and RMBS, in the same manner in which we value debt securities, as described above.

Foreign Securities: To value equity and fixed income securities traded on a foreign exchange or in foreign markets, we use their closing values under the generally accepted valuation method in the country where traded, as of the valuation date. We convert this to U.S. dollars at the exchange rate in effect on the valuation day. Under certain circumstances (for example, if there are significant movements in the United States markets and there is an

expectation the securities traded on foreign markets will adjust based on such movements when the foreign markets open the next day), the Account may adjust the value of equity or fixed income securities that trade on a foreign exchange or market after the foreign exchange or market has closed.

Investments Lacking Current Market Quotations: We value securities or other assets for which current market quotations are not readily available at fair value as determined in good faith under the direction of the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole. In evaluating fair value for the Account’s interest in certain commingled investment vehicles, the Account will generally look to the value periodically assigned to interests by the issuer. When possible, the Account will seek to have input in formulating the issuer’s valuation methodology.

Expense deductions

Expense deductions are made each valuation day from the net assets of the Account for various services to manage the Account’s investments, administer the Account and the contracts, distribute the contracts and to cover certain risks borne by TIAA. Investment management, administration and distribution services are provided “at cost” by TIAA and Services. Currently, TIAA provides investment management services and administration services for the Account, and Services provides distribution services for the Account. In addition, TIAA charges the Account a fee to bear certain mortality and expense risks, and risks associated with providing the liquidity guarantee. TIAA guarantees that in the aggregate, the expense charges will never be more than 2.50% of average net assets per year.

The estimated annual expense deduction rate that appears in the expense table below reflects an estimate of the amount we currently expect to deduct to approximate the costs that the Account will incur from May 1, 2017 through April 30, 2018 . Actual expenses may be higher or lower. The expenses identified in the table below do not include any fees which may be imposed by your employer under a plan maintained by your employer.

Since expenses for services provided to the Account are charged to the Account at cost, they are estimates for the year based on projected expense and asset levels. Administration charges include certain costs associated with the provision by TIAA entities of recordkeeping and other services for retirement plans and other pension products in addition to the Account. A portion of these expenses are allocated to the Account in accordance with applicable allocation procedures. In limited circumstances, TIAA may pay third parties for providing certain recordkeeping services for the Account.

At the end of every quarter, we reconcile the amount deducted from the Account during that quarter as discussed above with the expenses the Account actually incurred. If there is a difference, we add it to or deduct it from the Account in equal daily installments over the remaining days in the immediately following quarter, provided that material differences may be repaid in the current calendar quarter in accordance with GAAP. Our at-cost deductions are based on projections of Account assets and overall expenses, and the size of any adjusting payments will be directly affected by how different our projections are from the Account’s actual assets or expenses. The expenses identified in the table above do not include any fees which may be imposed by your employer under a plan maintained by your employer.

The size of the Account’s assets can be affected by many factors, including changes in the value of portfolio holdings, net income earned on the Account’s investments, premium activity and participant transfers into or out of the Account and participant cash withdrawals from the Account. In addition, our operating expenses can fluctuate based on a number of factors including participant transaction volume, operational efficiency, and technological, personnel and other infrastructure costs. Historically, the adjusting payments have resulted in both upward and downward adjustments to the Account’s expense deductions for the following quarter.

The Board can revise the estimated expense rates (the daily deduction rate before the quarterly adjustment referenced above) for the Account from time to time, usually on an annual basis, to keep deductions as close as possible to actual expenses.

Currently there are no deductions from premiums, transfers or withdrawals, but we reserve the right to change this in the future. Any such deductions would only be assessed to the extent the relevant contract provided for such deductions at the time the contract was issued.

Employer plan fee withdrawals

Your employer may, in accordance with the terms of your plan, and in accordance with TIAA’s policies and procedures, withdraw amounts from your Account accumulation under your Retirement Choice or Retirement Choice Plus contract, and, on a limited basis, under your GA, GSRA, GRA or Keogh contract, to pay fees associated with the administration of the plan. These fees are separate from the expense deductions of the Account and are not included for purposes of TIAA’s guarantee that the total annual expense deduction of the Account will not exceed 2.50% of average net assets per year.

The amount and the effective date of an employer plan fee withdrawal will be in accordance with the terms of your plan. TIAA will determine all values as of the end of the effective date. An employer plan fee withdrawal cannot be revoked after its effective date. Each employer plan fee withdrawal will be made on a pro rata basis from all your available TIAA and CREF accounts. An employer plan fee withdrawal reduces the accumulation from which it is paid by the amount withdrawn.

Certain relationships with TIAA

As noted elsewhere in this prospectus, the TIAA General Account plays a significant role in operating the Account, including providing a liquidity guarantee and investment advisory, administration and other services. In addition, Services, a wholly owned subsidiary of TIAA, provides distribution services for the Account.

Liquidity Guarantee. As noted above under the section entitled “Establishing and managing the Account — The role of TIAA — Liquidity guarantee,” if the Account’s liquid assets and its cash flow from operating activities and participant transactions are insufficient to fund redemption requests, the TIAA General Account has agreed to purchase liquidity units. TIAA thereby guarantees that a participant can redeem accumulation units at their net asset value next determined.

In the years ended December 31, 2008 and December 31, 2009, TIAA purchased liquidity units in a number of separate transactions at a purchase price equal to $155.6 million and approximately $1.1 billion, respectively. Since January 1, 2010 and through the date of this prospectus, the TIAA General Account has purchased no additional liquidity units. These liquidity units are valued in the same manner as are accumulation units held by the Account’s participants.

For the years ended December 31, 2016 , December 31, 2015 and December 31, 2014 , the Account expensed $38.4 million, $31.7 million and $29.2 million, respectively, for this liquidity guarantee from TIAA through a daily deduction from the net assets of the Account.

Investment Advisory, Administration and Distribution Services/Mortality and Expense Risks Borne by TIAA. As noted above under the section entitled “Expense deductions”, deductions are made each valuation day from the net assets of the Account for various services required to manage investments, administer the Account and distribute the contracts. These services are performed at cost by TIAA and Services. Deductions are also made each valuation day to cover mortality and expense risks borne by TIAA.

For the years ended December 31, 2016 , December 31, 2015 and December 31, 2014 , the Account expensed $72.6 million, $69.3 million and $70.7 million, respectively, for investment management services and $1.2 million, $1.1 million and $0.9 million, respectively, for mortality and expense risks provided/borne by TIAA. For the same

period, the Account expensed $89.8 million, $80.8 million and $62.2 million, respectively, for administrative and distribution services provided by TIAA and Services, as applicable.

Legal proceedings

The Account is party to various claims and routine litigation arising in the ordinary course of business. As of the date of this prospectus, management of the Account does not believe that the results of any such claims or litigation, individually or in the aggregate, will have a material effect on the Account’s business, financial position or results of operations.

The contracts

TIAA offers the Real Estate Account as a variable option for the annuity contracts described below. Some employer plans may not offer the Real Estate Account as an option for RA, GA, SRA, GRA, GSRA (including institutionally owned GSRA), Retirement Choice, Retirement Choice Plus or Keogh contracts. CREF is a companion organization to TIAA. A companion CREF contract may have been issued to you when you received the TIAA contract offering the Account. For more information about the CREF annuity contracts, the TIAA Traditional Annuity, the TIAA Access variable annuity accounts, other TIAA annuities and separate accounts offered from time to time and particular funds and investment options offered under the terms of your plan, please see the applicable contracts and respective prospectuses for those investment options.

Importantly, neither TIAA nor CREF guarantee the investment performance of the Account nor do they guarantee the value of your units at any time.

RA (Retirement Annuity) and GRA (Group Retirement Annuity)

RA and GRA contracts are used mainly for employee retirement plans. RA contracts are issued directly to you. GRA contracts, which are group contracts, are issued through an agreement between your employer and TIAA.

Depending on the terms of your employer’s plan, RA premiums can be paid by your employer, you, or both. GRA premiums can only be paid by your employer (though some such premiums may be paid by your employer pursuant to a salary reduction agreement). If you’re paying some or all of the entire periodic premium, your contributions can be in either pre-tax dollars by salary reduction or after-tax dollars by payroll deduction. Your employer may offer you the option of making contributions in the form of after-tax Roth IRA-style contributions, though you won’t be able to take tax deductions for these contributions. You can also transfer accumulations from another investment choice under your employer’s plan to your contract. Your GRA premiums can be from pre-tax or after-tax contributions. Ask your employer for more information about these contracts. As with RAs, you can transfer your accumulations from another investment choice under your employer’s plan to your GRA contract.

SRA (Supplemental Retirement Annuity) and GSRA (Group Supplemental Retirement Annuity)

These are generally limited to supplemental voluntary tax-deferred annuity (“TDA”) plans and supplemental 401(k) plans. SRA contracts are issued directly to you. GSRA contracts, which are group contracts, are issued through an agreement between your employer and TIAA. Generally, your employer pays premiums in pre-tax dollars through salary reduction. Your employer may offer you the option of making contributions in the form of after-tax Roth IRA-style contributions, though you won’t be able to take tax deductions for these contributions. Although you can’t pay premiums directly, you can transfer amounts from other TDA plans subject to the terms of the plan.

Retirement Choice/Retirement Choice Plus annuities

These are very similar in operation to the GRAs and GSRAs, respectively, except that, unlike GRAs, they are issued directly to your employer or your plan’s trustee, and they may be issued to your employer directly without participant recordkeeping. Among other rights, the employer retains the right to transfer accumulations under these contracts to alternate funding vehicles.

Classic IRA and Roth IRA

Classic IRAs are individual contracts issued directly to you. You and your spouse can each open a Classic IRA with an annual contribution of up to $5,500 or by rolling over funds from another IRA or eligible retirement plan, if you meet the Account’s eligibility requirements. If you are age 50 or older, you may contribute up to $6,500. The combined limit for your contributions to a Classic IRA and a Roth IRA for a single year is $5,500, or $6,500 if you are age 50 or older, excluding rollovers. (The dollar limits listed are for 2017; different dollar limits may apply in future years.)

Roth IRAs are also individual contracts issued directly to you. You and your spouse can each open a Roth IRA with an annual contribution up to $5,500 or with a rollover from another IRA or a Classic IRA issued by TIAA if you meet the Account’s eligibility requirements, subject to rules applicable to Roth IRA conversions. If you are age 50 or older you may contribute up to $6,500. The combined limit for your contributions to a Classic IRA and a Roth IRA for a single year is $5,500, or $6,500 if you are age 50 or older, excluding rollovers. (The dollar limits listed are for 2017; different dollar limits may apply in future years.)

We can’t issue a joint Classic IRA or Roth IRA contract. Your employer may offer SEP IRAs (Simplified Employee Retirement Plans), which are subject to different rules.

Classic and Roth IRAs may together be referred to as “IRAs” in this prospectus.

GA (Group Annuity) and institutionally owned GSRAs

These are used exclusively for employer retirement plans and are issued directly to your employer or your plan’s trustee. Your employer pays premiums directly to TIAA (you can’t pay the premiums directly to TIAA) and your employer or the plan’s trustee may control the allocation of contributions and transfers to and from these contracts including withdrawing completely from the Account. If a GA or Institutionally Owned GSRA contract is issued pursuant to your plan, the rules relating to transferring and withdrawing your money, receiving any annuity income or death benefits, and the timing of payments may be different, and are determined by your plan. Ask your employer or plan administrator for more information.

Keogh contracts

TIAA offered contracts under Keogh plans. If you are a self-employed individual who owns an unincorporated business, you could, prior to 2013, use the Account’s Keogh contracts for a Keogh plan, and cover common law employees, subject to the Account’s eligibility requirements. Note, however, that while TIAA will offer new contracts for new entrants into Keogh plans established prior to 2013, it will no longer offer contracts for Keogh plans that the Account is not currently funding.

ATRA (after-tax retirement annuity)

The after-tax retirement annuities (“ATRA”) are individual non-qualified deferred annuity contracts, issued to participants who are eligible and would like to remit personal premiums under the contractual provisions of their RA contract. To be eligible, you must have an active and premium-paying or paid up RA contract.

Note that the tax rules governing these non-qualified contracts differ significantly from the treatment of qualified contracts. Please see the section below entitled “Taxes” for more information.

Eligibility for IRA and Keogh contracts

Each of you and your spouse can open a Classic or Roth IRA or a Keogh, subject to the limitations described above, if you’re a current or retired employee or trustee of an Eligible Institution, or if you own a TIAA or CREF annuity contract or a TIAA individual insurance contract. To be considered a retired employee for this purpose, an individual must be at least 55 years old and have completed at least three years of service at an Eligible Institution. In the case of partnerships, at least half the partners must be eligible individuals and the partnership itself must be primarily engaged in education or research. Eligibility may be restricted by certain income limits on opening Roth IRA contracts.

State regulatory approval

State regulatory approval may be pending for certain of these contracts, and these contracts may not currently be available in your state.

Starting out

Generally, we’ll issue you a TIAA contract when we receive a completed application or enrollment form in good order. “Good order” means actual receipt of the transaction request along with all information and supporting legal documentation necessary to effect the transaction. This information and documentation generally includes your complete application and any other information or supporting documentation we may require. With respect to purchase requests, “good order” also generally includes receipt of sufficient funds by us to effect the transaction. We may, in our sole discretion, determine whether any particular transaction request is in good order and reserve the right to change or waive any good order requirement at any time either in general or with respect to a particular plan, contract or transaction.

If your application is incomplete and we do not receive the necessary information and signed application in good order within five business days of our receipt of the initial premium, we will return the initial premium at that time.

If we receive premiums from your employer and, where applicable, a completed application from you before we receive your specific allocation instructions (or if your allocation instructions violate employer plan restrictions or do not total 100%), we will invest all premiums remitted on your behalf in the default option your employer has designated. It is possible that the default option will not be the Real Estate Account but will be another investment option available under your plan. We consider your employer’s designation of a default option to be an instruction to us to allocate your premiums to that option as described above. You should consult your plan documents or sales representative to determine your employer’s designated default option and to obtain information about that option. Further, to the extent you hold an IRA contract, the default option will be that fund or account specified in your IRA forms.

When we receive complete allocation instructions from you in good order, we’ll follow your instructions for future premiums. However, if you want the premiums previously allocated to the default option (and earnings and losses on them) to be transferred to the options identified in your instructions, you must specifically request that we transfer these amounts from the default option to your investment option choices.

Amounts may be invested in an account other than the Real Estate Account (absent a participant’s specific instructions) only in the limited circumstances identified in the paragraph immediately above and the circumstances outlined under the section below entitled “How to transfer and withdraw your money — Restrictions on premiums and transfers to the Account”, namely: (1) we receive premiums before we receive your completed application or allocation instructions, (2) a participant’s allocations violate employer plan restrictions or do not total 100%, or (3) we stop accepting premiums for and/or transfers into the Account.

TIAA doesn’t generally restrict the amount or frequency of payment of premiums to your contract, although we may in the future. Your employer’s retirement plan may limit your premium amounts. There also may be restrictions on remitting premiums on an IRA. In addition, the Code limits the total annual premiums you may invest in plans qualified for favorable tax treatment. If you want to directly contribute personal premiums under the contractual provisions of your RA contract, you will be issued an ATRA contract. Premiums and any earnings on the ATRA contract will not be subject to your employer’s retirement plan. The restrictions relating to these premiums are in the contract itself.

In most cases (subject to any restriction we may impose, as described in this prospectus), TIAA accepts premiums to a contract during your accumulation period. Once your first premium has been paid, your TIAA contract can’t lapse or be forfeited for nonpayment of premiums. However, TIAA can stop accepting premiums to the Real Estate Account at any time.

You may remit premium payments to the following address: P.O. Box 1259, Charlotte, N.C. 28201.

Note that we cannot accept money orders or travelers checks. In addition, we will not accept a third-party check where the relationship of the payor to the account owner cannot be identified from the face of the check.

You will receive a confirmation statement each time you make a transfer to, a transfer out, or a cash withdrawal from the Account. The statement will show the date and amount of each transaction. However, if you’re remitting premiums through an employer or other qualified plan, using an automatic investment plan or systematic withdrawal plan, you may instead receive a statement confirming those transactions following the end of each calendar quarter.

If you have any accumulations in the Account, you will be sent a statement in each quarter which sets forth the following information:

You also will receive reports containing the financial statements of the Account and certain information about the Account’s investments.

Important information about procedures for opening a new account

To help the U.S. government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account.

What this means for you: When you open an account, we will ask for your name, street address (not a post office box), date of birth, Social Security number and other information that will allow us to identify you, such as your home telephone number and driver’s license or certain other identifying documents. Until you provide us with the information needed, we may not be able to open an account or effect any transactions for you. Furthermore, if we are unable to verify your identity, or that of another person authorized to act on your behalf, or if it is believed that potentially criminal activity has been identified, we reserve the right to take such action as deemed appropriate, which may include closing your account.

Choosing among investment accounts

Once an account is opened on your behalf, you may allocate all or part of your premiums to the Real Estate Account, unless your employer’s plan precludes that choice. You can also allocate premiums to TIAA’s Traditional Annuity, the CREF variable investment accounts, the TIAA Access variable annuity accounts, other TIAA annuities and separate accounts offered from time to time (if available under the terms of your employer’s plan) and, in some cases, certain funds if the account or fund is available under your employer’s plan.

You can change your allocation choices for future premiums by:

The right to cancel your contract

Generally, you may cancel any RA, SRA, GSRA, Classic IRA, Roth IRA, ATRA or Keogh contract in accordance with the contract’s Right to Examine provision (unless we have begun making annuity payments from it) and subject to the time period regulated by the state in which the contract is issued. Although the contract terms and state law provisions differ, you will generally have between 10 and 60 days to exercise this cancellation right. To cancel a contract, you must mail or deliver the contract with your cancellation instructions (or signed Notice of Cancellation when such has been provided with your contract) to our home office. We’ll cancel the contract, then send either the current accumulation or the premium, depending on the state in which your contract was issued, to whomever originally submitted the premiums. Unless we are returning premiums paid as required by state law, you will bear the investment risk during this period.

Determining the value of your interest in the account — accumulation units

Each payment to the Real Estate Account buys a number of accumulation units. Similarly, any withdrawal from the Account results in the redemption of a number of accumulation units. The price you pay for accumulation units, and the price you receive for accumulation units when you redeem accumulation units, is the value of the accumulation units calculated for the business day on which we receive your purchase, redemption or transfer request in good order (unless you ask for a later date for a redemption or transfer). This date is called the “effective

date.” Therefore, if we receive your purchase, redemption or transfer request in good order before the NYSE closes, that business day will be considered the effective date of your order. If we receive your request in good order after the NYSE closes, the next business day will be considered the effective date of your order.

Payments and orders to redeem accumulation units (or adjustments thereto) may be processed after the effective date. “Processed” means when amounts are credited or debited to you in the Account. In the event there are market fluctuations between the effective date and the processing date and the price of accumulation units on the processing date is higher or lower than your price on the effective date, that difference will be paid or retained by Services, the Account’s distributor. This amount, which may be positive or negative, together with similar amounts paid or retained by Services in connection with transactions involving other investment products offered under pension plans administered by TIAA or its affiliates and the amount of interest, if any, paid by Services to participants in connection with certain delayed payments, is apportioned to the Account pursuant to an agreement with Services, under which the Account reimburses Services for the services it has provided to the Account.

The accumulation unit value reflects the Account’s investment experience ( i.e. , the real estate net operating income accrued, as well as dividends, interest and other income accrued), realized and unrealized capital gains and losses, as well as Account expense charges.

Calculating Accumulation Unit Values: We calculate the Account’s accumulation unit value at the end of each valuation day. To do that, we multiply the previous day’s value by the net investment factor for the Account. The net investment factor is calculated as A divided by B, where A and B are defined as:

How to transfer and withdraw your money

Generally, depending on the terms of your plan, contracts, tax law and applicable governing documents, TIAA allows you to move your money to and from the Real Estate Account in the following ways:

For more information regarding the transfer policies of CREF, TIAA Access, TIAA’s Traditional Annuity or another investment option listed above, please see the respective contract, prospectus or other governing instrument. These options may be limited by the terms of your employer’s plan, by current tax law, or by the terms of your contract, as set forth below.

Currently, transfers from the Real Estate Account to any TIAA annuity offered by your employer’s plan, to one of the CREF accounts or to funds offered under the terms of your plan must generally be at least $1,000 (except for systematic transfers, which must be at least $100) or your entire accumulation, if less. In the future, we may

eliminate these minimum transaction levels. Lump sum cash withdrawals from the Real Estate Account and transfers to other companies are not subject to a minimum amount. Transfers and cash withdrawals are currently free. TIAA can place restrictions on transfers or charge fees for transfers and/or withdrawals in the future.

As indicated, transfers and cash withdrawals are effective at the end of the business day we receive your request and all required documentation in good order. You can also choose to have transfers and withdrawals take effect at the close of any future valuation day. For any transfers to TIAA’s Traditional Annuity, the crediting rate will be the rate in effect at the close of business of the first day that you participate in TIAA’s Traditional Annuity, which is the next business day after the effective date of the transfer.

To request a transfer or to withdraw cash, you may:

If you are married, and all or part of your accumulation is attributable to contributions made under

You may be required to complete and return certain forms (in good order) to effect these transactions. We can limit, suspend or terminate your ability to transact by telephone, over the Internet, or by fax at any time, for any reason.

Before you transfer or withdraw cash, please make sure that you consult the terms of your employer’s plan, as it may contain additional restrictions. In addition, please make sure you understand the possible federal and other income tax consequences. Please see the section below entitled “Taxes.”

Transfers to and from other TIAA-CREF accounts and funds

Transfers from the Real Estate Account. Once every calendar quarter you can transfer some or all of your accumulation in the Real Estate Account to the following accounts if offered by your employer's plan or IRA: TIAA’s Traditional Annuity, to another TIAA annuity, to one of the CREF accounts, to a TIAA Access variable annuity account or to funds (which may include TIAA-CREF affiliated funds). Transfers to TIAA’s Traditional Annuity or other TIAA annuities or accounts, a CREF account or to certain other options may be restricted by your employer’s plan, current tax law or by the terms of your contract. In addition, there are important exceptions to this once per calendar quarter limitation, as outlined in the section below entitled “How to transfer and withdraw your money — Market timing/excessive trading policy.”

Transfers to the Real Estate Account. Currently, you can also transfer some or all of your accumulation in TIAA’s Traditional Annuity, in your CREF accounts, TIAA Access variable annuity accounts or in the funds or TIAA annuities offered under the terms of your plan to the Real Estate Account, if your employer’s plan offers the Account; subject to the terms of the plan, current tax law and the terms of your contract. Transfers from TIAA’s Traditional Annuity to the Real Estate Account under RA, GRA or Retirement Choice contracts can only be effected over a period of time (up to 10 annual installments) and may be subject to other limitations, as specified in your contract. Amounts held under an ATRA contract cannot be transferred to or from any retirement plan contract.

Currently, these transfers must generally be at least $1,000 (except for systematic transfers, which must be at least $100) or your entire accumulation, if less. Because excessive transfer activity can hurt Account performance and other participants, subject to applicable state law and the terms of your contract, we may seek to further limit how often, or in what amounts, you may make transfers, or we may otherwise modify the transfer privilege generally. Please see the section below entitled “How to transfer and withdraw your money — Restrictions on premiums and transfers to the Account.”

Transfers to other companies

Generally you may transfer funds from the Real Estate Account to a company other than TIAA or CREF, subject to certain tax restrictions. This right may be limited by your employer’s plan or the terms of your contract. If your

employer participates in our special transfer services program, we can make automatic monthly transfers from your RA or GRA contract to another company. Roth amounts in a 403(b) or 401(a) plan can only be rolled over to another Roth account under such plan or to a Roth IRA, as permitted by applicable law and the terms of the plans. IRA to IRA rollover rules have recently changed. See the section below entitled “Taxes” for more information on these developments.

Under the Retirement Choice and Retirement Choice Plus contracts, your employer could transfer monies from the Account and apply it to another account or investment option, subject to the terms of your plan, and without your consent.

Transfers from other companies/plans

Subject to your employer’s plan and federal tax law, you can usually transfer or roll over money from another 403(b), 401(a)/403(a) or governmental 457(b) retirement plan to your qualified TIAA contract. You may also roll over before-tax amounts in a Traditional IRA to 403(b) plans, 401(a)/403(a) plans or eligible governmental 457(b) plans, provided such employer plans agree to accept the rollover. Roth amounts in a 403(b) or 401(a) plan can only be rolled over to another Roth account under such plan or to a Roth IRA, as permitted by applicable law and the terms of the plans. Funds in a private 457(b) plan can be transferred to another private 457(b) plan only. Accumulations in private 457(b) plans may not be rolled over to a qualified plan ( e.g ., a 401(a) plan), a 403(b) plan, a governmental 457(b) plan or an IRA. IRA to IRA rollover rules have recently changed. See the section below entitled “Taxes” for more information on these developments.

Withdrawing cash

You may withdraw cash from your SRA, GSRA, IRA, ATRA or Keogh Real Estate Account accumulation at any time during the accumulation period, provided federal tax law and the terms of your employer’s plan permit it (see below). Normally, you can’t withdraw money from a contract if you’ve already applied that money to begin receiving lifetime annuity income. Current federal tax law restricts your ability to make cash withdrawals from your accumulation under most voluntary salary reduction agreements. In addition, if you are married, you may be required by law or your employer’s plan to show us advance written consent from your spouse before TIAA makes certain transactions on your behalf.

Withdrawals are generally available only if you reach age 59½, leave your job, become disabled, die, satisfy requirements related to qualified reservist distributions or if your employer terminates its retirement plan. If your employer’s plan permits, you may also be able to withdraw money if you encounter hardship, as defined by the IRS, but hardship withdrawals can be from contributions only, and not investment earnings. You may be subject to a 10% penalty tax if you make a withdrawal before you reach age 59½, unless an exception applies to your situation.

Under current federal tax law, you are not permitted to withdraw from 457(b) plans earlier than the calendar year in which you reach age 70½, leave your job or are faced with an unforeseeable emergency (as defined by law). There are generally no early withdrawal tax penalties if you withdraw under any of these circumstances ( i.e., no 10% tax on distributions prior to age 59½).

Special rules and restrictions apply to Classic and Roth IRAs.

If you request a withdrawal, we will send the proceeds by check to the address of record, or by electronic funds transfer to the bank account on file. A letter of instruction with a bank signature guarantee is required if the withdrawal is sent to an address other than the address of record, or to an address of record that has been changed within either the last 30 or 14 calendar days, depending on the service model applicable to your plan. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange. A notary public cannot provide a signature guarantee. Proceeds directed to a bank account not on file have similar restrictions that require completion of a verification process. Please contact us for further information. We reserve the right to require a signature guarantee on any redemption.

Systematic withdrawals and transfers

If your employer’s plan allows, you can set up a program to make cash withdrawals or transfers automatically by specifying that we withdraw from your Real Estate Account accumulation, or transfer to or from the Real Estate Account, any fixed number of accumulation units, dollar amount, or percentage of accumulation until you tell us to stop or until your accumulation is exhausted. Currently, the program must be set up so that at least $100 is automatically transferred or withdrawn at a time. In the future, we may eliminate this minimum transfer amount.

Further, a systematic plan of this type may allow pre-specified transfers or withdrawals to be made more often than quarterly, depending on the terms of your employer’s plan. Additional restrictions on systematic transfers may apply for Account participants with accumulation amounts exceeding $150,000. See "Restrictions on premiums and transfers to the Account" below.

Withdrawals to pay financial advisor fees

If permitted by your employer’s plan, you may authorize a series of systematic withdrawals to pay the fees of a financial advisor. Such systematic withdrawals are subject to all provisions applicable to systematic withdrawals, except as otherwise described in this section. One series of systematic withdrawals to pay financial advisor fees may be in effect at the same time that one other series of systematic withdrawals is also in effect. Systematic withdrawals to pay financial advisor fees must be scheduled to be made quarterly only, on the first day of each calendar quarter. The amount withdrawn from each investment account must be specified in dollars or as a percentage of accumulation, and will be in proportion to the accumulations in each account at the end of the business day prior to the withdrawal. The financial advisor may request that we stop making withdrawals. We reserve the right to determine the eligibility of financial advisors for this type of fee reimbursement. Before you set up this program, make sure you understand the possible tax consequences of these withdrawals. Please see the discussion in the section below entitled “Taxes.”

Restrictions on premiums and transfers to the Account

From time to time we may stop accepting premiums for and/or transfers into the Account. We might do so if, for example, we can’t find sufficient appropriate real estate-related investment opportunities at a particular time. Whenever reasonably possible, we will notify you before we decide to restrict premiums and/or transfers. However, because we may need to respond quickly to changing market conditions or to the liquidity needs and demands of the Account, we reserve the right (subject to the terms of some contracts) to stop accepting premiums and/or transfers at any time without prior notice.

Individual participants are limited from making internal funding vehicle transfers into their Account accumulation if, after giving effect to such transfer, the total value of such participant’s Account accumulation (under all contracts issued to such participant) would exceed $150,000.

As of the date of this prospectus, all jurisdictions in which the Account is offered have approved this limitation, but the effective date of the limitation as applies to an individual participant will be reflected on his or her applicable contract or endorsement form. These contracts or endorsements will contain important details with respect to this limitation.

Under this limitation, an internal funding vehicle transfer means the movement (or attempted movement) of accumulations from any of the following to the Account:

The following transfers are currently not subject to this limitation:

This limitation does not apply to most types of premium contributions and certain group contracts recordkept on non-TIAA platforms. Minimum Distribution Option (“MDO”) contracts will be subject to this limitation, but the limitation does not apply to other annuity pay-out contracts.

A transfer which cannot be applied pursuant to this limitation, along with any other attempted movements of funds submitted as part of a noncompliant transfer request into the Account, will be rejected in its entirety, and therefore the funds that were to be transferred will remain in the investment option from which the transfer was to be made. The Account accumulation unit values used in applying this provision will be those calculated as of the

valuation day preceding the day on which the proposed transfer is to be effective. A participant will not be required to reduce his or her accumulation to a level at or below $150,000 if the total value of the participant’s Account accumulation under all contracts exceeds $150,000 on the effective date as indicated in the contract or contract endorsement. TIAA reserves the right in the future to modify the nature of this limitation and to include categories of transactions associated with services that may be introduced in the future.

If we decide to stop accepting premiums into the Account, amounts that would otherwise be allocated to the Account will be allocated to the default option designated by your employer instead (or the default option specified on your IRA forms), unless you give us other allocation instructions. We will not transfer these amounts out of the default option designated by your employer when the restriction period is over, unless you request that we do so. However, we will resume allocating premiums to the Account on the date we remove the restrictions.

Additional limitations

Federal law requires us to obtain, verify and record information that identifies each person who opens an account. Until we receive the information we need, we may not be able to effect transactions for you. Furthermore, if we are unable to verify your identity, or that of another person authorized to act on your behalf, or if we believe that we have identified potentially criminal activity, we reserve the right to take such action as we deem appropriate, which may include closing your account.

Market timing/excessive trading policy

There are participants who may try to profit from making transactions back and forth among the CREF accounts, the Account, the TIAA Access variable account and the funds or other investment options available under the terms of your plan in an effort to “time” the market or for other reasons. As money is shifted in and out of these accounts, the accounts or funds may incur transaction costs, including, among other things, expenses for buying and selling securities. These costs are borne by all participants, including long-term investors who do not generate these costs. In addition, excessive trading can interfere with efficient portfolio management and cause dilution if traders are able to take advantage of pricing inefficiencies. Consequently, the Account is not appropriate for market timing or frequent trading and you should not invest in the Account if you want to engage in such activity.

To discourage this activity, transfers of accumulations from the Real Estate Account to a CREF or TIAA account, or another investment option, are limited to once every calendar quarter. A few limited exceptions to this once per calendar quarter limitation apply, including:

TIAA reserves the right to reject any purchase or exchange request with respect to the Account, including when it is believed that a request would be disruptive to the Account’s efficient portfolio management. TIAA also may suspend or terminate your ability to transact in the Account by telephone, fax or over the Internet for any reason, including the prevention of excessive trading. A purchase or exchange request could be rejected or electronic trading privileges could be suspended because of the timing or amount of the investment or because of a history of excessive trading by the participant. Because TIAA has discretion in applying this policy, it is possible that similar transaction activity could be handled differently because of the surrounding circumstances.

Notwithstanding such discretion, TIAA seeks to apply its excessive trading policies and procedures uniformly to all Account participants. As circumstances warrant, TIAA may request transaction data from intermediaries from time to time to verify whether the Account’s policies are being followed and/or to instruct intermediaries to take action against participants who have violated the Account’s policies. TIAA has the right to modify these policies and procedures at any time without advance notice.

The Account is not appropriate for excessive trading. You should not invest in the Account if you want to engage in excessive trading or market timing activity. Participants seeking to engage in excessive trading may deploy a variety of strategies to avoid detection, and, despite TIAA’s efforts to discourage excessive trading, there is no guarantee that TIAA or its agents will be able to identify all such participants or curtail their trading practices.

If you invest in the Account through an intermediary, including through a retirement or employee benefit plan, you may be subject to additional market timing or excessive trading policies implemented by the intermediary or plan. Please contact your intermediary or plan sponsor for more details.

When you are ready to receive annuity income

The annuity period in general

You can receive an income stream from all or part of an accumulation in the Account. Generally, once distributions are permitted to begin under your plan or contract, you may begin to receive income from a lifetime annuity. You should be at least age 59½ to begin receiving annuity income other than from a lifetime annuity. Otherwise, you may have to pay a 10% penalty tax on the taxable amount, except under certain circumstances. In addition, you cannot begin receiving income later than permitted under the minimum distribution rules of the Code. See “Taxes” for more information. Also, under the terms of the contract, you cannot begin a life annuity after age 90 or a joint life annuity after either you or your annuity partner reaches age 90.

Your income payments may be paid out from the Account through a variety of income options. You can pick a different income option for different portions of your accumulation, but once you’ve started payments you usually cannot change your income option or annuity partner for that payment stream. Usually income payments are monthly. You can choose quarterly, semiannual and annual payments as well. TIAA has the right to not make payments at any interval that would cause the initial payment to be less than $100.) We will send your payments by mail to your home address or, on your request, by mail or electronic funds transfer to your bank.

Your initial income payments are based on the value of your accumulation on the last valuation day before the annuity starting date. We calculate initial income based on:

· the amount of money you have accumulated in the Account

· the income option or options you choose; and

· an assumed annual investment return of 4% and, for life annuities, mortality assumptions for you and your annuity partner, if you have one.

On your annuity starting date, for any payout annuities denominated in annuity units, all of your accumulation units will be converted to annuity units of the Account .

There are two income change methods for annuity payments: annual and monthly. Under the annual income change method, payments change each May 1, based on the net investment results of the Account during the prior year (from the day following the last Valuation Day in March of the prior year through the last Valuation Day in March of the current year). Under the monthly income change method, payments change every month, based on the net investment results during the previous valuation period. Under this method, we value annuity units on the 20th of each month or on the preceding Business Day if the 20th is not a Business Day. The total value of your annuity payments may be more or less than your total premiums.

Impact of mortality experience on annuity payments

How much you or your beneficiary receive in annuity payments from any Account will depend in part on the mortality experience of the annuity fund (annually revalued or monthly revalued) from which the payments are made. For example, if the people receiving income from an Account’s annually revalued annuity fund live longer, as a group, than expected, the amount payable to each will be less than if they as a group die sooner than expected. So the “mortality risk” of each Account’s annuity fund falls on those who receive income from it and is not guaranteed by TIAA.

Annuity starting date

Ordinarily, annuity payments begin on the date you designate as your annuity starting date, provided we have received all documentation necessary for the income option you have picked. If something is missing, we will defer your annuity starting date until we receive the missing information. Your first annuity check may be delayed while we process your choice of income options and calculate the amount of your initial payment. You may designate any future date for your annuitization request, in accordance with our procedures and as long as it is one on which we process annuitizations.

Any premiums received within 70 days after payments begin may be used to provide additional annuity income. Premiums received after 70 days will remain in your accumulating annuity contract until you have given further instructions. Ordinarily, your first annuity payment can be made on any business day between the first and twentieth of any month.

Annuity income options

Both the number of annuity units you purchase and the amount of your income payments will depend on which income option(s) you pick. Your employer’s plan, tax law and ERISA may limit which income options you can use to receive income from an RA, GRA, SRA, GSRA, Retirement Choice, Retirement Choice Plus, or Keogh Contract. Ordinarily, you will choose your income options shortly before you want payments to begin, but you can make or change your choice any time before your annuity starting date.

All of the income options provide variable payments, and the amount of income you receive depends in part on the investment experience of the investment accounts selected by you. The current options are:

You can change your mind during the Income Test Drive, and future payments will stop when you notify us of your decision. At the end of the Income Test Drive, if you have not decided to stop payments, your

remaining accumulation applied to the Income Test Drive feature will be converted to annuity units payable under the income option you chose when you started this feature. Once the conversion to annuity units takes place, it is irrevocable. If you decide before the end of the Income Test Drive that you want to begin annuity income immediately, you may do so subject to certain election procedures. The conversion of accumulation units to annuity units may result in annuity payments that are greater or lesser than the amount of the last payment during the Income Test Drive.

State regulatory approval may be pending for the Income Test Drive and it may not currently be available in your state. We may stop providing the Income Test Drive feature at any time. For information about withdrawals from your contract, see “How to transfer and withdraw your money.”

For any of the income options described above, current federal tax law provides that your guaranteed period can’t exceed the joint life expectancy of you and your beneficiary or annuity partner. Other code stipulations may make some income options unavailable to you. If you are married at your annuity start date, you may be required by law to choose an income option that provides survivor annuity income to your spouse, unless your spouse waives the right.

Receiving Lump-Sum Payments (Retirement Transition Benefit): If your employer’s plan allows, you may be able to receive a single sum payment of up to 10% of the value of any part of an accumulation being converted to annuity income on the annuity starting date. Such employer plan and 10% limitations do not apply to IRAs . Of course, if your employer’s plan allows cash withdrawals, you can take a larger amount (up to 100%) of your accumulation as a cash payment. The retirement transition benefit will be subject to current federal income tax requirements and possible early distribution penalties. See “Taxes.”

Other income options may become available in the future, subject to the terms of your retirement plan and relevant federal and state laws. TIAA may stop offering certain income options in the future. For more information about any annuity option, please contact TIAA.

Transfers during the annuity period

After you begin receiving annuity income, you can transfer all or part of the future annuity income (which is the actuarial present value of the payments based on the applicable interest rate and the mortality basis associated with that fund at the time of the transfer) payable once each calendar quarter (i) from the Real Estate Account into a “comparable annuity” payable from a CREF or TIAA account or TIAA’s Traditional Annuity, or (ii) from a CREF or TIAA variable account into a comparable annuity payable from the Real Estate Account. Comparable annuities are those which are payable under the same income option and have the same first and second annuitant, and remaining guaranteed period.

We’ll process your transfer on the business day we receive your request in good order. You can also choose to have a transfer take effect at the close of any future business day. Transfers under the annual income payment method will affect your annuity payments beginning on the May 1 following the March 31 which is on or after the effective date of the transfer. Transfers under the monthly income payment method and all transfers into TIAA’s Traditional Annuity will affect your annuity payments beginning with the first payment due after the monthly payment valuation day that is on or after the transfer date. You can switch between the annual and monthly income change methods, and the switch will go into effect on the last valuation day of March. Although the payout streams are actuarially equivalent and there is no charge for engaging in such a transfer, it is possible that the new funds may apply different mortality or interest assumptions, and could therefore result in variation between the initial payments from the new fund and the payments that were being made out of the original fund.

Annuity payments

The amount of annuity payments we pay you or your beneficiary (annuitant) will depend upon the number and value of the annuity units payable. The number of annuity units is first determined on the day before the annuity starting date. The amount of the annuity payments will change according to the income change method chosen.

Under the annual income change method, the value of an annuity unit for payments is redetermined on March 31 of each year (or, if March 31 is not a valuation day, the immediately preceding valuation day). This date is called the “annual payment valuation day.” Annuity payments change beginning May 1. The change reflects the net investment experience of the Real Estate Account. The net investment experience for the twelve months following the annual payment valuation day will be reflected in the annuity unit value determined on the next year’s annual payment valuation day.

Under the monthly income change method, the value of an annuity unit for payments is determined on the payment valuation day, which is the 20th day of the month preceding the payment due date or, if the 20th is not a business day, the preceding business day. The monthly changes in the value of an annuity unit reflect the net investment experience of the Real Estate Account. The formulas for calculating the number and value of annuity units payable are described below.

Calculating the Number of Annuity Units Payable: When a participant or a beneficiary converts the value of all or a portion of his or her accumulation into an income-paying contract, the number of annuity units payable from the Real Estate Account under an income change method is determined by dividing the value of the Account accumulation to be applied to provide the annuity payments by the product of the annuity unit value for that income change method and an annuity factor. The annuity factor as of the annuity starting date is the value of an annuity in the amount of $1.00 per month beginning on the first day such annuity units are payable, and continuing for as long as such annuity units are payable.

The annuity factor will reflect interest assumed at the effective annual rate of 4%, and the mortality assumptions for the person(s) on whose life (lives) the annuity payments will be based. Mortality assumptions will be based on the then-current settlement mortality schedules for this Account. Annuitants bear no mortality risk under their contracts — actual mortality experience will not reduce annuity payments after they have started. TIAA may change the mortality assumptions used to determine the number of annuity units payable for any future accumulations converted to provide annuity payments.

The number of annuity units payable under an income change method under your contract will be reduced by the number of annuity units you transfer out of that income change method under your contract. The number of annuity units payable will be increased by any internal transfers you make to that income change method under your contract.

Value of Annuity Units: The Real Estate Account’s annuity unit value is calculated separately for each income change method for each valuation day. The annuity unit value for each income change method is determined by updating the annuity unit value from the previous valuation day to reflect the net investment performance of the Account for the current valuation period relative to the 4% assumed investment return. In general, your payments will increase if the performance of the Account is greater than 4% and decrease if the value is less than 4%. The value is further adjusted to take into account any changes expected to occur in the future at revaluation either once a year or once a month, assuming the Account will earn the 4% assumed investment return in the future.

The initial value of the annuity unit for a new annuitant is the value determined as of the valuation day before annuity payments start.

For participants under the annual income change method, the value of the annuity unit for payment remains level until the following May 1. For those who have already begun receiving annuity income as of March 31, the value of the annuity unit for payments due on and after the next succeeding May 1 is equal to the annuity unit value determined as of the last valuation day in March.

For participants under the monthly income change method, the value of the annuity unit for payments changes on the payment valuation day of each month for the payment due on the first of the following month.

Further, certain variable annuity payouts might not be available if issuing the payout annuity would violate state law.

TIAA reserves the right, subject to approval by the Board of Trustees, to modify the manner in which the number and/or value of annuity units is calculated in the future. No such modification will reduce any participant’s benefit once the participant’s annuitization period has commenced.

Death benefits

Choosing beneficiaries

Subject to the terms of your employer’s plan, death benefits under TIAA contracts are payable to the beneficiaries you name. When you purchase your annuity contract, you name one or more beneficiaries to receive the death benefit if you die. You can generally change your beneficiaries any time before you die, and, unless you instruct otherwise, your annuity partner can do the same after your death.

Amount of death benefit

If you die during the accumulation period, the death benefit is the amount of your accumulation. If you and your annuity partner die during the annuity period while payments are still due under a fixed-period annuity or for the remainder of a guaranteed period, the death benefit is the present value, based on an specified effective annual interest rate, of the unit annuity payments due for the remainder of the period.

Payment of death benefit

To authorize payment and pay a death benefit, we must have received all necessary forms and documentation (in good order), including proof of death and the selection of the method of payment.

Every state has some form of unclaimed property laws that impose varying legal and practical obligations on insurers and, indirectly, on contractowners, insureds, beneficiaries and other payees of proceeds. Unclaimed property laws generally provide for escheatment to the state of unclaimed proceeds under various circumstances.

Contractowners are urged to keep their own, as well as their insureds’, beneficiaries’ and other payees’, information up to date, including full names, postal and electronic media addresses, telephone numbers, dates of birth, and Social Security numbers. Such updates should be communicated in writing to TIAA at P.O. Box 1259, Charlotte, NC 28201, by calling our Automated Telephone Service (24 hours a day) at 800 842-2252 or via www.tiaa.org.

Methods of payment of death benefits

Generally, you can choose for your beneficiary the method we will use to pay the death benefit, but few participants do this. If you choose a payment method, you can also prevent your beneficiaries from changing it. Most people leave the choice to their beneficiaries. We can prevent any choice if its initial payment is less than $25. If your beneficiary does not specifically instruct us to start paying death benefits within a year of your death, we can start making payments to them over five years using the fixed-period annuity method of payment.

Payments during accumulation period : Currently, the available methods of payment for death benefits from funds in the accumulation period are:

 

 

 

 

Death benefits are usually paid monthly (unless you chose a single-sum method of payment), but your beneficiary can switch them to quarterly, semiannual or annual payments. Note that for Retirement Choice and Retirement Choice Plus contracts, beneficiaries may only receive either a single-sum payment or a one-life annuity (with or without a guaranteed benefit in the plan).

 

Payments during annuity period: If you and your annuity partner die during the annuity period, your beneficiary can choose to receive any remaining guaranteed periodic payments due under your contract. Alternatively, your beneficiary can choose to receive the commuted value of those payments in a single sum unless you have indicated otherwise. The amount of the commuted value will be different from the total of the periodic payments that would otherwise be paid.

Ordinarily, death benefits are subject to federal tax. If taken as a lump sum, death benefits would be taxed like complete withdrawals. If taken as annuity benefits, the death benefit would be taxed like annuity payments. For more information, see the discussion under “Taxes” below.

Employer plan fee withdrawals

Your employer may, in accordance with the terms of your plan, and with TIAA’s approval, withdraw amounts from your accumulations under your Retirement Choice or Retirement Choice Plus contract, and, if your certificate so

provides, on your GRA or GSRA, or GA contract, to pay fees associated with the administration of the plan. TIAA also reserves the right to suspend or reinstate its approval for a plan to make such withdrawals. The amount and the effective date of an employer plan fee withdrawal will be in accordance with the terms of your plan. TIAA will determine all values as of the end of the effective date under the plan.

An employer plan fee withdrawal cannot be revoked after its effective date under the plan. Each employer plan fee withdrawal will be made on a pro-rata basis from all your available TIAA and CREF Accounts. An employer plan fee withdrawal reduces the accumulation from which it is paid by the amount withdrawn. If allowed by your contract, your employer may also charge a fee on your Account to pay fees associated with administering the plan.

Your spouse’s rights to death benefits

In general, your choice of beneficiary for death benefits may, in some cases, be subject to the consent of your spouse. Similarly, if you are married at the time of your death, federal law may generally require a portion of the death benefit be paid to your spouse even if you have named someone else as beneficiary. If you die without having named any beneficiary, any portion of your death benefit not payable to your spouse will generally go to your estate unless your employer’s plan provides otherwise.

If you are married, and all or part of your accumulation is attributable to contributions made under:

 

 

 

Your spouse may consent to a waiver of his or her rights to these benefits.

Waiver of spouse’s rights to death benefits

If you are married, and all or part of your accumulation is attributable to contributions made under:

 

 

 

 

 

In order to waive the rights to spousal survivor benefits, we must receive, in a form satisfactory to us, your spouse’s consent, or a satisfactory verification that your spouse cannot be located. A waiver of rights with respect to an income option or a lump-sum benefit must be made in accordance with the IRC and ERISA, or the applicable provisions of your employer plan. A waiver of the survivor death benefit may not be effective if it is made prior to the earlier of the plan year in which you reach age 35 or your severance from employment of your employer.

Verification of your marital status may be required, in a form satisfactory to us, for purposes of establishing your spouse’s rights to benefits or a waiver of these rights. (For more information about the definition of a “spouse”, see “Taxes-Federal Defense of Marriage Act.”) You may revoke a waiver of your spouse’s rights to benefits at any time during your lifetime and before the annuity starting date. Your spouse may not revoke a consent to a waiver after the consent has been given.

Taxes

This section offers general information concerning federal taxes. It doesn’t cover every situation. Tax treatment varies depending on the circumstances, and state and local taxes may also be involved. For complete information on your personal tax situation, check with a qualified tax advisor.

How the Real Estate Account is treated for tax purposes

The Account is not a separate taxpayer for purposes of the Code — its earnings are taxed as part of TIAA’s operations. Although TIAA is not expected to owe any federal income taxes on the Account’s earnings, if TIAA does incur taxes attributable to the Account, it may make a corresponding charge against the Account.

Taxes in general

During the accumulation period, Real Estate Account premiums paid in before-tax dollars, employer contributions and earnings attributable to these amounts are not taxed until they’re withdrawn. Annuity payments, single-sum withdrawals, systematic withdrawals, and death benefits are usually taxed as ordinary income. Premiums paid in after-tax dollars aren’t taxable when withdrawn, but earnings attributable to these amounts are taxable unless those amounts are contributed as Roth contributions to a 401(a), 403(b) or governmental 457(b) plan and certain criteria are met before the amounts (and the income on the amounts) are withdrawn. Generally, transfers between qualified retirement plans are not taxed.

After prevailing in Bobrow v. Commissioner , T.C. Memo. 2014-21, the Internal Revenue Service announced a significant change in the longstanding position on the treatment on multiple IRA rollovers occurring in a 12 month period. Federal tax law permits only one tax-deferred rollover between IRAs of distributions taken in a 12 month period. The IRS had previously interpreted that restriction to apply separately to each IRA owned by an individual. However, in the Bobrow case the Tax Court held that the 12 month restriction period applied to all of the taxpayer’s traditional IRAs. The IRS has issued guidance expanding this new interpretation of the one-rollover- per-year rule to all types of IRAs. Please consult your qualified tax adviser for more information before making any IRA rollover.

Generally, contributions you can make under an employer’s plan are limited by federal tax law. Employee voluntary salary reduction contributions and Roth after-tax contributions to 403(b) and 401(k) plans are limited in the aggregate to $18,000 per year ($24,000 per year if you are age 50 or older). Certain long-term employees may be able to defer additional amounts to a 403(b) plan. Contributions to Classic and Roth IRAs, other than rollover contributions, cannot generally exceed $5,500 per year ($6,500 per year for taxpayers age 50 or older). The maximum contribution limit to a 457(b) non-qualified deferred compensation plan for employees of state and local governments is $18,000 ($24,000 if you are age 50 or older). Special catch-up rules may permit a higher contribution in one or more of the last three years prior to an individual’s normal retirement age under the plan.

Note that the dollar limits listed above are for 2017; different dollar limits may apply in future years.

Early distributions

If you want to withdraw funds or begin receiving income from any 401(a), 403(a), or 403(b) retirement plan or an IRA before you reach age 59½, you may have to pay a 10 percent early distribution tax on the taxable amount. Distributions from a Roth IRA generally are not taxed, except that, once aggregate distributions exceed contributions to the Roth IRA, income tax and a 10% penalty tax may apply to distributions made (1) before age 59½ (subject to certain exceptions) or (2) during the five taxable years starting with the year in which the first contribution is made to any Roth IRA. A 10% penalty tax may apply to amounts attributable to a conversion from an IRA if they are distributed during the five taxable years beginning with the year in which the conversion was made. You won’t have to pay this tax in certain circumstances. Early distributions from 457(b) plans are not subject to a 10% penalty tax unless, in the case of a governmental 457(b) plan, the distribution includes amounts rolled over to the plan from an IRA, 401(a)/403(a), or 403(b) plan. Consult your tax advisor for more information.

Minimum distribution requirements

In most cases, payments from qualified contracts must begin by April 1 of the year after the year you reach age 70½, or if later, by retirement. For Classic IRAs, and with respect to 5% or more owners of the business covered by a Keogh plan, payments must begin by April 1 of the year after you reach age 70½. Under the terms of certain retirement plans, the plan administrator may direct us to make the minimum distributions required by law even if you do not

elect to receive them. In addition, if you don’t begin distributions on time, you may be subject to a 50% excise tax on the amount you should have received but did not. Roth IRAs are generally not subject to these rules requiring minimum distributions during your lifetime. You are responsible for requesting distributions that comply with the minimum distribution rules. Please consult your tax advisor for more information.

Premium taxes

Some states assess premium taxes on the premiums paid under the contract. We will deduct the total amount of premium taxes, if any, from your accumulation based on current state insurance laws, subject to the provisions of your contract, and our status in the state. Generally, premium taxes range from 0% to 3.5%, depending on the state.

Withholding on distributions

If we pay an “eligible rollover” distribution directly to you, federal law requires us to withhold 20% from the taxable portion. On the other hand, if we roll over such a distribution directly to an IRA or employer plan, we do not withhold any federal income tax. The 20% withholding also does not apply to certain types of distributions that are not considered eligible rollovers such as payments from IRAs, hardship withdrawals, lifetime annuity payments, substantially equal periodic payments over your life expectancy or over 10 or more years, or minimum distribution payments.

For the taxable portion of non-eligible rollover distributions, we will usually withhold federal income taxes unless you tell us not to and you are eligible to avoid withholding. However, if you tell us not to withhold but we don’t have your taxpayer identification number on file, we still are required to withhold taxes. These rules also apply to distributions from governmental 457(b) plans. In general, all amounts received under a private 457(b) plan are taxable and are subject to federal income tax withholding as wages. Nonresident aliens who pay U.S. taxes are subject to different withholding rules.

Federal estate, gift, and generation-skipping transfer taxes

While no attempt is being made to discuss in detail the federal estate tax implications of the contract, a purchaser should keep in mind that the value of an annuity contract owned by a decedent and payable to a beneficiary who survives the decedent is included in the decedent’s gross estate. Depending on the terms of the contract, the value of the annuity included in the gross estate may be the value of the lump sum payment payable to the designated beneficiary or the actuarial value of the payments to be received by the beneficiary. Consult an estate planning advisor for more information.

Under certain circumstances, the Code may impose a generation-skipping (“GST”) tax when all or part of an annuity contract is transferred to, or a death benefit is paid to, an individual two or more generations younger than the contract owner. Regulations issued under the Code may require us to deduct the tax from your contract, or from any applicable payment, and pay it directly to the IRS. For 2016, the federal estate tax, gift tax, and GST tax exemptions and maximum rates are $5,450,000 and 40%, respectively. The potential application of these taxes underscores the importance of seeking guidance from a qualified adviser to help ensure that your estate plan adequately addresses your needs and those of your beneficiaries under all possible scenarios.

Federal defense of marriage act

The right of a spouse to continue the contract and all contract provisions relating to spouses and spousal continuation are available only to a person who meets the definition of “spouse” under federal law. The U.S. Supreme Court has held Section 3 of the federal Defense of Marriage Act (which did not recognize same-sex marriages, even those that were permitted under individual state laws) to be unconstitutional. Therefore, same-sex marriages recognized under state or foreign law will be recognized for federal law purposes. The U.S. Department of the Treasury and the Internal Revenue Service have determined that for federal tax purposes, same-sex spouses will be determined based on the law of the state in which the marriage was celebrated irrespective of the law of the state in which the person resides. IRS guidance provides that civil unions and similar relationships recognized under state law are not marriages unless denominated as such. Consult a qualified tax adviser for more information on this subject.

Special rules for after-tax retirement annuities

If you paid premiums directly to an RA and the premiums are not subject to your employer’s retirement plan, or if you have been issued an ATRA contract, the following general discussion describes our understanding of current federal income tax law that applies to these accumulations. This discussion does not apply to premiums paid on your behalf under the terms of your employer’s retirement plan. It also does not cover every situation and does not address all possible circumstances.

In General. These annuities are generally not taxed until distributions occur. When distributions occur, they are taxed as follows:

Required Distributions. In general, if you die after you start your annuity payments but before the entire interest in the annuity contract has been distributed, the remaining portion must be distributed at least as quickly as under the method in effect on the date of your death. If you die before your annuity payments begin, the entire interest in your annuity contract generally must be distributed within five years after your death, or be used to provide payments that begin within one year of your death and that will be made for the life of your designated beneficiary or for a period not extending beyond the life expectancy of your designated beneficiary. The “designated beneficiary” refers to a natural person you designate and to whom ownership of the contract passes because of your death. However, if the designated beneficiary is your surviving spouse, your surviving spouse can continue the annuity contract as the new owner.

Death Benefit Proceeds. Death benefit proceeds are taxed like withdrawals of the entire accumulation in the contract if distributed in a single sum and are taxed like annuity payments if distributed as annuity payments. Your beneficiary may be required to take death benefit proceeds within a certain time period.

Penalty Tax on Certain Distributions. You may have to pay a penalty tax (10% of the amount treated as taxable income) on distributions you take prior to age 59½. There are some exceptions to this rule, however. You should consult a tax advisor for information about those exceptions.

Withholding. Annuity distributions are generally subject to federal income tax withholding but most recipients can usually choose not to have the tax withheld.

Certain Designations or Exchanges. Designating an annuitant, payee or other beneficiary, or exchanging a contract may have tax consequences that should be discussed with a tax advisor before you engage in any of these transactions.

Multiple Contracts. All non-qualified deferred annuity contracts issued by us and certain of our affiliates to the same owner during a calendar year must generally be treated as a single contract in determining when and how much income is taxable and how much income is subject to the 10% penalty tax (see above).

Diversification Requirements. The investments of the Real Estate Account must be “adequately diversified” in order for the ATRA Contracts to be treated as annuity contracts for Federal income tax purposes. It is intended that Real Estate Account will satisfy these diversification requirements.

Owner Control. In certain circumstances, owners of non-qualified variable annuity contracts have been considered for Federal income tax purposes to be the owners of the assets of the separate account supporting their contracts due to their ability to exercise investment control over those assets. When this is the case, the contract owners have been currently taxed on income and gains attributable to the variable account assets. While we believe that the ATRA Contracts do not give you investment control over assets in the Real Estate Account or any other separate account underlying your ATRA Contract, we reserve the right to modify the ATRA Contracts as necessary to prevent you from being treated as an owner of the assets in the Real Estate Account.

Premium Taxes. Some states, the District of Columbia, and Puerto Rico assess premium taxes on the premiums paid under the ATRA contract. We will deduct the total amount of premium taxes, if any, from your accumulation based on current state insurance laws, subject to the provisions of your contract, and our status in the state. Generally, the premium taxes range from 0.5% to 3.5% (6% for Puerto Rico) depending on the state.

Residents of Puerto Rico

The IRS has announced that income from an annuity received by residents of Puerto Rico is U.S.-source income that is generally subject to United States federal income tax.

Annuity purchases by nonresident aliens

The discussion above provides general information regarding U.S. federal income tax consequences to annuity purchasers that are U.S. citizens or residents. Purchasers that are not U.S. citizens or residents will generally be subject to U.S. federal withholding tax on taxable distributions from annuity contracts at a 30% rate, unless a lower treaty rate applies. In addition, purchasers may be subject to state and/or municipal taxes and taxes that may be imposed by the purchaser’s country of citizenship or residence. Prospective purchasers who are nonresident aliens are advised to consult with a qualified tax adviser regarding U.S., state, and foreign taxation with respect to an annuity contract purchase.

Special rules for withdrawals to pay advisory fees

If you have arranged for us to pay advisory fees to your financial advisor from your accumulations, those partial withdrawals generally will not be treated as taxable distributions as long as:

However, withdrawals to pay advisory fees to your financial advisor from your accumulations under an ATRA contract will be treated as taxable distributions.

Foreign tax credit

The Account may be subject to foreign taxes on investments in other countries, including capital gains tax on any appreciation in value when a real estate investment in a foreign jurisdiction is eventually sold. Any potential tax impact will not be reflected in the valuation of the foreign investment and may not be fully reflected in a tax accrual by the Account. Upon payment of any foreign tax by the Account, TIAA may be eligible to receive a foreign tax credit, which (subject to certain limitations) may be available to reduce its U.S. tax burden. The Account is a segregated asset account of TIAA and incurs no material federal income tax attributable to the investment performance of the Account under the Code. As a result, the Account will not realize any tax benefit from any foreign tax credit that may be available to TIAA; however, to the extent that TIAA can utilize the foreign tax credit in its consolidated tax return, TIAA will reimburse the Account for that benefit at that time. The extent to which TIAA is able to utilize the credits when the Account incurs a foreign tax will determine the amount and timing of reimbursement from TIAA to the Account for the resulting foreign tax credit. The Account’s unit values may be adversely impacted in the future if a foreign tax is paid, and TIAA is not able to utilize (and therefore does not reimburse the Account for), either immediately or in the future, the foreign tax credit earned as a result of the foreign tax paid by the Account.

Possible tax law changes

Although the likelihood of legislative changes is uncertain, there is always the possibility that the tax treatment of your contract could change by legislation or otherwise. Consult a tax advisor with respect to legislative developments and their effect on your contract.

We have the right to modify the contract in response to legislative changes that could otherwise diminish the favorable tax treatment that annuity contract owners currently receive. We make no guarantee regarding the tax status of any contract and do not intend the above discussion as tax advice.

General matters

Making choices and changes

You may have to make certain choices or changes ( e.g ., changing your income option, making a cash withdrawal) by written notice in good order satisfactory to us and received at our home office or at some other location that we have specifically designated for that purpose. When we receive a notice of a change in beneficiary or other person named to receive payments, we’ll execute the change as of the date it was signed, even if the signer has died in the meantime. We execute all other changes as of the date received.

Telephone and internet transactions

You can use our Automated Telephone Service (“ATS”) or the TIAA Web Center’s account access feature to check your account balances, transfer to TIAA’s Traditional Annuity, TIAA Access variable annuity accounts or CREF, and/or allocate future premiums among the accounts and funds available to you through TIAA. Note that, currently, all requests to make lump-sum transfers out of the Real Estate Account to another investment option (whether or not affiliated with TIAA or CREF) may not be made by means of TIAA’s Internet website. You will be asked to enter your Personal Identification Number (“PIN”) and Social Security number for both systems. (You can establish a PIN by calling us.) Both will lead you through the transaction process and will use reasonable procedures to confirm that instructions given are genuine. If we use such procedures, we are not responsible for incorrect or fraudulent transactions. All transactions made over the ATS and Internet are electronically recorded.

To use the ATS, you need a touch-tone phone. The toll free number for the ATS is 800 842-2252. To use the Internet, go to the account access feature of the TIAA Web Center at www.tiaa.org. We can suspend or terminate your ability to transact by telephone, over the Internet, or by fax at any time, for any reason.

Voting rights

You don’t have the right to vote on the management and operation of the Account directly; however, you may send ballots to advise the TIAA Board of Overseers about voting for nominees for the TIAA Board of Trustees.

Electronic prospectus

If you received this prospectus electronically and would like a paper copy, please call 877 518-9161 and we will send it to you. Under certain circumstances where we are legally required to deliver a prospectus to you, we cannot send you a prospectus electronically unless you’ve consented.

Householding

To lower costs and eliminate duplicate documents sent to your home, we may begin mailing only one copy of the Account’s prospectus, prospectus supplements or any other required documents to your household, even if more than one participant lives there. If you would prefer to continue receiving your own copy of any of these documents, you may call us toll-free at 877 518-9161, or write us.

Miscellaneous policies

Amending the Contracts: The contract may be amended by agreement of TIAA and the contractholder without the consent of any other person, provided that such change does not reduce any benefit purchased under the contract up to that time. Any endorsement or amendment of the contract, waiver of any of its provisions, or change in rate schedule will be valid only if in writing and signed by an executive officer of TIAA.

If You’re Married: If you’re married, you may be required by law or your employer’s plan to get advance written consent from your spouse before we make certain transactions for you. If you’re married at your annuity starting date, you may also be required by law or your employer’s plan to choose an income option that provides survivor annuity income to your spouse, unless he or she waives that right in writing. There are limited exceptions to the waiver requirement.

Texas Optional Retirement Program Restrictions: If you’re in the Texas Optional Retirement Program, you or your beneficiary can redeem some or all of your accumulation only if you retire, die, or leave your job in the state’s public institutions of higher education.

Assigning Your Contract: Generally, neither you nor your beneficiaries can assign your ownership of a TIAA retirement contract to anyone else.

Overpayment of Premiums: If your employer mistakenly sends more premiums on your behalf than you’re entitled to under your employer’s retirement plan or the Code, we’ll refund them to your employer as long as we’re requested to do so (in writing) before you start receiving annuity income.

Any time there’s a question about premium refunds, TIAA will rely on information from your employer. If you’ve withdrawn or transferred the amounts involved from your accumulation, we won’t refund them.

Errors or Omissions: We reserve the right to correct any errors or omissions on any form, report, or statement that we send you.

Payment to an Estate, Guardian, Trustee, etc.: We reserve the right to pay in one sum the commuted value of any benefits due an estate, corporation, partnership, trustee, or other entity not a natural person. Neither TIAA nor the Account will be responsible for the conduct of any executor, trustee, guardian, or other third party to whom payment is made.

Benefits Based on Incorrect Information: If the amounts of benefits provided under a contract were based on information that is incorrect, benefits will be recalculated on the basis of the correct data. If the Account has overpaid or underpaid, appropriate adjustments will be made.

Proof of Survival: We reserve the right to require satisfactory proof that anyone named to receive benefits under a contract is living on the date payment is due. If we have not received this proof after we request it in writing, the Account will have the right to make reduced payments or to withhold payments entirely until such proof is received.
