PART I

ITEM 1A. 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. 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 Annual Report on 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 entitled “Forward-Looking Statements ,” which is contained in the section entitled “Management’s Discussion and Analysis of the Account’s Financial Condition and Results of Operations.”

RISKS ASSOCIATED WITH REAL ESTATE INVESTING

General Risks of Acquiring and Owning Real Property: As referenced elsewhere in this report, the substantial majority of the Account’s net assets are comprised 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.

10

				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.
•				Leasing Risk. A number of factors could cause the Account’s rental income, a key source of the Account’s revenue and investment return, to decline, which would adversely impact the Account’s results and investment returns. These factors include the following:

•				A property may be unable to attract new tenants or retain existing tenants. This situation could be exacerbated if a concentration of lease expirations occurred during any one time period or multiple tenants exercise early termination at the same time.
•				The financial condition of our tenants may be adversely impacted, particularly in a prolonged economic downturn. The Account could lose revenue if tenants do not pay rent when contractually obligated, request some form of rent relief and/or default under a lease at one of the Account’s properties. Such a default could occur if a tenant declared bankruptcy, suffered from a lack of liquidity, failed to continue to operate its business or for other reasons. In the event of any such default, we may experience a delay in, or an inability to effect, the enforcement of our rights against that tenant, particularly if that tenant filed for bankruptcy protection. Further, any disputes with tenants could involve costly and time consuming litigation.
•				In the event a tenant vacates its space at one of the Account’s properties, whether as a result of a default, the expiration of the lease term, rejection of the lease in bankruptcy or otherwise, given current market conditions, we may not be able to re-lease the vacant space either (i) for as much as the rent payable under the previous lease or (ii) at all. Also, we may not be able to re-lease such space without incurring 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 some instances, our properties may be specifically suited to and/or outfitted for the particular needs of a certain tenant based on the type of business the tenant operates. For example, many companies desire space with an open floor plan. We may have difficulty obtaining a new tenant for any vacant space in our properties, particularly if the floor plan limits the types of businesses that can use the space without major renovation, which may require us to incur substantial expense in re-planning the space. Also, upon expiration of a lease, the space preferences of our major tenants may no longer align with the space they previously rented, which could cause those tenants to not renew their lease, or may require us to expend significant sums to reconfigure the space to their needs.
•				The Account owns and operates retail properties, which, in addition to the risks listed above, are subject to specific risks, including the insolvency and/or closing of an anchor tenant. Many times, anchor tenants will be “big box” stores and other large retailers that can be particularly adversely impacted by a global recession and reduced consumer spending generally. Factors that can impact the level of consumer spending include increases in fuel and energy costs, residential and commercial real estate and mortgage conditions, labor and healthcare costs, access to credit, consumer confidence and other macroeconomic factors. Under certain circumstances, co-tenancy clauses in tenants’ leases may allow certain tenants in a retail property to terminate their leases or reduce or withhold rental payments when overall occupancy at the property falls below certain minimum levels. The insolvency and/or closing of an anchor tenant may also cause such tenants to terminate their leases, or to fail to renew their leases at expiration.

•				Competition. The Account may face competition for real estate investments from multiple sources, including individuals, corporations, insurance companies or other insurance company separate accounts, as well as real estate limited partnerships, real estate investment funds, commercial developers, pension

11

				plans, other institutional and foreign investors and other entities engaged in real estate investment activities. Some of these competitors may have similar financial and other resources as the Account, and/or they may have investment strategies and policies (including the ability to incur significantly more leverage than the Account) that allow them to compete more aggressively for real estate investment opportunities, which could result in the Account paying higher prices for investments, experiencing delays in acquiring investments or failing to consummate such purchases. Any resulting delays in the acquisition of investments, or the failure to consummate acquisitions the Account deems desirable, may increase the Account’s costs or otherwise adversely affect the Account’s investment results.
				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.
•				Operating Costs. A property’s cash flow could decrease if operating costs, such as property taxes, utilities, litigation expenses associated with a property, maintenance and insurance costs that are not reimbursed by tenants increase in relation to gross rental income, or if the property needs unanticipated repairs and renovations. In addition, the Account’s expenses of owning and operating a property are not necessarily reduced when income from a property is reduced.
•				Condemnation. A governmental agency may condemn and convert for a public use ( i.e. , through eminent domain) all or a portion of a property owned by the Account. While the Account would receive compensation in connection with any such condemnation, such compensation may not be in an amount the Account believes represents equivalent value for the condemned property. Further, a partial condemnation could impair the ability of the Account to maximize the value of the property during its operation, including making it more difficult to find new tenants or retain existing tenants. Finally, a property which has been subject to a partial condemnation may be more difficult to sell at a price the Account believes is appropriate.
•				Terrorism and Acts of War and Violence. Terrorist attacks may harm our property investments. The Account cannot assure you that there will not be further terrorist attacks against the United States, U.S. businesses or elsewhere in the world. These attacks or armed conflicts may directly or indirectly impact the value of the property we own or that secure our loans. Losses resulting from these types of events may be 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 and worldwide financial markets and 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 the investment return.

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

12

•				The Account may need to provide financing to a purchaser if no cash buyers are available, or if buyers are unable to receive financing on terms enabling them to consummate the purchase. Such seller financing introduces a risk that the counterparty may not perform its obligations to repay the amounts borrowed from the Account to complete the purchase.
•				For any particular property, the Account may be required to make expenditures for improvements to, or to correct defects in, the property before the Account is able to market and/or sell the property.
•				Interest in real estate limited partnerships tend to be, in particular, illiquid, and the Account may be unable to dispose of such investments at opportune times.

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. Recent disruptions in the macroeconomy, real estate markets and the credit markets have led to a significant decline in transaction activity in most markets and sectors and the lack of observable transaction data may have made it more difficult for an appraisal to determine the fair value of the Account’s real estate. 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

13

magnitude or the timing of such item. 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 report, the Account intends to hold between 15% and 25% of its net assets in investments other than real estate and real estate-related investments, comprised 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. See “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 report, 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, 2012, the Account’s non-real estate-related liquid assets comprised 17.4% 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, 2012, the Account’s loan to value ratio was approximately 21.0%. 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:

14

•				General Economic Conditions. General economic conditions, dislocations in the capital or credit markets generally or the market conditions then in effect in the real estate finance industry, may hinder the Account’s ability to obtain financing or refinancing for its property investments on
				favorable terms or at all, regardless of the quality of the Account’s property for which financing or refinancing is sought. Such unfavorable terms might include high interest rates, increased fees and costs and restrictive covenants applicable to the Account’s operation of the property. Longer term disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation, reduced alternatives or failures of significant financial institutions could adversely affect our access to financing necessary to make profitable real estate investments. Our failure to obtain financing or refinancing on favorable terms due to the current state of the credit markets or otherwise could have an adverse impact on the returns of the Account. The negative effects presently remaining in the marketplace from the worldwide economic slowdown following the banking crisis of 2008 and the ongoing sovereign debt and banking difficulties recently experienced in parts of the Eurozone could affect the Account’s ability to secure financing. These difficulties include tighter lending standards instituted by banks and financial institutions, the reduced availability of credit facilities and project finance facilities from banks and the fall of consumer and/or business confidence.
•				Default Risk. The property or group of encumbered properties may not generate sufficient cash flow to support the debt service on the loan, the property may fail to meet certain financial or operating covenants contained in the loan documents and/or the property may have negative equity ( i.e. , the loan balance exceeds the value of the property) or inadequate equity. In any of these circumstances, we may default on the loan, including due to the failure to make required debt service payments when due. If a loan is in default, the Account may determine that it is not economically desirable and/or in the best interests of the Account to continue to make payments on the loan (including accessing other sources of funds to support debt service on the loan), and/or the Account may not be able to otherwise remedy such default on commercially reasonable terms or at all. In either case, the lender then could accelerate the outstanding amount due on the loan and/or foreclose on the underlying property, in which case the Account could lose the value of its investment in the foreclosed property. Further, any such default or acceleration could trigger a default under loan agreements in respect of other Account properties pledged as security for the defaulted loan or other loans. Finally, any such default could increase the Account’s borrowing costs, or result in less favorable terms, with respect to financing future properties.
•				Balloon Maturities. If the Account obtains a mortgage loan that involves a balloon payment, there is a risk that the Account may not be able to make the lump sum principal payment due under the loan at the end of 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.
•				Variable Interest Rate Risk. If the Account obtains variable-rate loans, the Account’s returns may be volatile when interest rates are volatile. Further, to the extent that the Account takes out fixed-rate loans and interest rates subsequently decline, this may cause the Account to pay interest at above-market rates for a significant period of time. Any hedging activities the Account engages in to mitigate this risk may not fully protect the Account from the impact of interest rate volatility.
•				Variable Rate Demand Obligation (“VRDO”) Risk. To the extent the Account obtains financing pursuant to a variable rate demand obligation subject to periodic remarketing or similar mechanisms, the Account or the joint ventures in which it invests could face higher borrowing costs if the remarketing results in a higher prevailing interest rate. In addition, the terms of such variable rate obligations may allow the remarketing agent to cause the Account or venture to repay the loan on demand in the event insufficient market demand for such loans is present. In particular, RGM 42, LLC, a joint venture in which the Account holds a 70% interest, is the borrower under a VRDO loan program, as described in more detail in “Management’s Discussion and Analysis of the Account’s Financial Condition and Results of Operations.”
•				Valuation Risk. The market valuation of mortgage loans payable could have an adverse impact on the Account’s performance. Valuations of mortgage loans payable are generally based on the amount at

15

				which the liability could be transferred in a current transaction, exclusive of transaction costs, and such valuations are subject to a number of assumptions and factors with respect to the loan and the underlying property, a change in any of which could cause the value of a mortgage loan to fluctuate.

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 are 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:

16

•				There are risks associated with potential underperformance or nonperformance by, and/or solvency of a contractor we select or other third party vendors involved in developing or redeveloping the property.
•				If the Account were viewed as developing or redeveloping underperforming properties, suffering losses on our investments, or defaulting on any loans on our properties, our reputation could be damaged. Damage to our reputation could make it more difficult to successfully develop or acquire properties in the future and to continue to grow and expand our relationships with our lenders, venture partners and tenants.
•				Because external factors may have changed from when the project was originally conceived ( e.g., slower growth in the local economy, higher interest rates, overbuilding in the area, or changes in the regulatory and permitting environment), the property may not attract tenants on the schedule we originally planned and/or may not operate at the income and expense levels first projected.

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.

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 multifamily residential 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. 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 cleanup 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

17

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 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, 2012, REIT securities comprised approximately 9.0% 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 a REIT security 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 generally 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, continued 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 mortgage 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 are comprised 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

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

CONFLICTS OF INTEREST WITHIN TIAA

General. TIAA and its affiliates (including TIAA-CREF Alternative Advisors, LLC and Teachers Advisors, Inc., its wholly owned subsidiaries and registered investment advisers) have interests in other real estate programs and accounts and also engage in other business activities and 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 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 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

21

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 other current and potential TIAA-sponsored investment vehicles 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 report, 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 and has initiated systematic redemptions of liquidity units owned by the TIAA General Account which were purchased during the period of significant net participant transfers out of the Account in late 2008 and early 2009. TIAA’s ownership of liquidity units (including the potential for changes in its levels of ownership in the future) 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 “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.
