Accounting Policies [Abstract] | |
Organization and Significant Accounting Policies | Organization and Significant Accounting Policies Business: The TIAA Real Estate Account (“Account”) is an insurance separate account of Teachers Insurance and Annuity Association of America (“TIAA”) and was established by resolution of TIAA’s Board of Trustees (the “Board”) on February 22, 1995, under the insurance laws of the State of New York, for the purpose of funding variable annuity contracts issued by TIAA. 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, and make withdrawals from the Account on a daily basis, 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. The investment objective of the Account is to seek favorable long-term returns primarily through rental income and capital appreciation from real estate and real estate-related investments owned by the Account. The Account holds real estate properties directly and through subsidiaries wholly-owned by TIAA for the benefit of the Account. The Account also holds limited interests in real estate joint ventures and limited partnerships, as well as investments in loans receivable with commercial real estate properties as underlying collateral. Additionally, the Account invests in real estate-related and non-real estate-related publicly traded securities, cash and other instruments to maintain adequate liquidity levels for operating expenses, capital expenditures and to fund benefit payments (withdrawals, transfers and related transactions). Basis of Presentation: The accompanying Consolidated Financial Statements include the Account and those subsidiaries wholly-owned by TIAA for the benefit of the Account. All significant intercompany accounts and transactions between the Account and such subsidiaries have been eliminated. The Consolidated Financial Statements were prepared in accordance with accounting principles generally accepted in the United States of America, which requires the use of estimates made by management. Actual results may vary from those estimates and such differences may be material. The following is a summary of the significant accounting policies of the Account. The Accumulation Unit Value (“AUV”) used for financial reporting purposes may differ from the AUV used for processing transactions. The AUV used for financial reporting purposes includes security and participant transactions effective through the period end date to which this report relates. Total return is computed based on the AUV used for processing transactions. Determination of Investments at Fair Value: The Account reports all investments at fair value in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. Further in accordance with the adoption of the fair value option allowed under ASC 825, Financial Instruments , and at the election of Account management, mortgage loans payable are reported at fair value. The FASB has defined fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The following is a description of the valuation methodologies used to determine the fair value of the Account’s investments and investment related mortgage loans payable. Valuation of Real Estate Properties —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. Determination of fair value involves significant levels of judgment because the actual fair value of real estate can be determined only by negotiation between the parties in a sales transaction. The Account’s primary objective when valuing its real estate investments will be to produce a valuation that represents a reasonable estimate of the fair value of its investments. Implicit in the Account’s definition of fair value are the consummation of a sale as of a specified date and the passing of title from seller to buyer under conditions whereby: • Buyer and seller are typically motivated; • Both parties are well informed or well advised, and acting in what they consider their best interests; • A reasonable time is allowed for exposure in the open market; • Payment is made in terms of cash or in terms of financial arrangements comparable thereto; and • The price represents the normal consideration for the property sold unaffected by special or creative financing or sales concessions granted by anyone associated with the sale. 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. Key inputs and assumptions include rental income and expense amounts, related rental income and expense growth rates, capital expenditures, discount rates and capitalization rates. Valuation techniques include discounted cash flow analysis, prevailing market capitalization rates or multiples applied to earnings from the property, analysis of recent comparable sales transactions, actual sale negotiations and bona fide purchase offers received from third parties. Amounts ultimately realized from each investment may vary significantly from the fair value presented. Real estate properties owned by the Account are initially valued based on an independent third party appraisal, as reviewed by TIAA’s internal appraisal staff and as applicable by the Account’s independent fiduciary at the time of the closing of the purchase. Such initial valuation 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 is appraised each quarter by an independent third party appraiser, reviewed by TIAA’s internal appraisal staff and as applicable the Account’s independent fiduciary. 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 such adjustments are made) that happen regularly throughout each quarter and not on one specific day or month in each period. 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 the account receives a bona fide bid for the sale of a property held within the Account or one of the Account’s joint ventures. 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). Alternatively, adjustments may be made to reflect the execution or renewal of a significant lease. 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. TIAA’s internal appraisal staff oversees the entire appraisal process, in conjunction with the Account’s independent fiduciary (the independent fiduciary is more fully described in the following paragraph). 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). The independent fiduciary, RERC, LLC, has been appointed by a special subcommittee of the Investment Committee of the Board to, among other things, oversee the appraisal process. The independent fiduciary must approve all independent appraisers used by the Account. All appraisals are performed in accordance with Uniform Standards of Professional Appraisal Practices, the real estate appraisal industry standards created by The Appraisal Foundation. Real estate appraisals are estimates of property values based on a professional’s opinion. Appraisals of properties held outside of the U.S. are performed in accordance with industry standards commonly applied in the applicable jurisdiction. These independent appraisers 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. Also, the independent fiduciary can require additional appraisals if factors or events have occurred that could materially change a property’s value (including those identified above) and such change is not reflected in the quarterly valuation review, or otherwise to ensure that the Account is valued appropriately. The independent fiduciary must also approve any valuation change of real estate-related assets where a property’s value changed by more than 6% from the most recent independent annual appraisal, or if the value of the Account would change by more than 4% within any calendar quarter or more than 2% since the prior calendar month. When a real estate property is subject to a mortgage, the property is valued independently of the mortgage and the property and mortgage fair values are reported separately (see Valuation of Mortgage Loans Payable ). The independent fiduciary reviews and approves all mortgage valuation adjustments before such adjustments are recorded by the Account. The Account continues 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. Valuation of Real Estate Joint Ventures —Real estate joint ventures are stated at the fair value of the Account’s ownership interests of 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. 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. Valuation of Real Estate Limited Partnerships —Limited partnership interests are stated at the fair value of the Account’s ownership in the partnership which are recorded based upon the changes in the net asset values of the limited partnerships as determined from the financial statements of the limited partnerships when received by the Account. Prior to the receipt of the financial statements from the limited partnerships, the Account estimates the value of its interest in good faith and will from time to time seek input from the issuer or the sponsor of the investments. Since market quotations are not readily available, the limited partnership interests are valued at fair value as determined in good faith by management under the direction of the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole. Valuation of Marketable Securities —Equity securities listed or traded on any national market or exchange are valued at the last sale price as of the close of the principal securities market or exchange on which such securities are traded or, if there is no sale, at the mean of the last bid and asked prices on such market or exchange, exclusive of transaction costs. Debt securities with readily available market quotations, other than money market instruments, are generally valued at the most recent bid price or the equivalent quoted yield for such securities (or those of comparable maturity, quality and type). 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 are valued in the same manner as debt securities, as described above. Money market instruments are valued at amortized cost, which approximates fair value. Equity and fixed income securities traded on a foreign exchange or in foreign markets are valued using their closing values under the valuation methods generally accepted in the country where traded, as of the valuation date. This value is converted 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 U.S. 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. Valuation of 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 by TIAA’s internal valuation department 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 (such as the loan-to-value ratio and the cash flow of the underlying collateral) and the credit quality of the counterparty. The independent fiduciary reviews and approves all loan receivable valuation adjustments before such adjustments are recorded by the Account. The Account continues to use the revised value for each loan receivable to calculate the Account’s daily net asset value until the next valuation review. Loan origination costs are expensed as incurred. Valuation of Mortgage Loans Payable (i.e. the Account as a debtor) —Mortgage loans payable are stated at fair value. The estimated fair values of mortgage loans payable are based on the amount at which the liability could be transferred to a third party exclusive of transaction costs. Mortgage loans payable are valued internally by TIAA’s internal valuation department, as reviewed by the Account’s independent fiduciary, at least quarterly based on market factors, such as market interest rates and spreads for comparable loans, the performance of the underlying collateral (such as the loan-to-value ratio and the cash flow of the underlying collateral), the liquidity for mortgage loans of similar characteristics, the maturity date of the loan and the return demands of the market. See Note 5 — Assets and Liabilities Measured at Fair Value on a Recurring Basis for further discussion and disclosure regarding the determination of the fair value of the Account’s investments. Foreign Currency Transactions and Translation: Portfolio investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of securities, income receipts and expense payments made in foreign currencies are translated into U.S. dollars at the exchange rates prevailing on the respective dates of the transactions. The effect of any changes in foreign currency exchange rates on portfolio investments and mortgage loans payable are included in net realized and unrealized gains and losses on real estate properties and mortgage loans payable. Net realized gains and losses on foreign currency transactions include disposition of foreign currencies, and currency gains and losses between the accrual and receipt dates of portfolio investment income and between the trade and settlement dates of portfolio investment transactions. Accumulation and Annuity Funds: The accumulation fund represents the net assets attributable to participants in the accumulation phase of their investment (“Accumulation Fund”). The annuity fund represents the net assets attributable to the participants currently receiving annuity payments (“Annuity Fund”). The net increase or decrease in net assets from investment operations is apportioned between the accounts based upon their relative daily net asset values. Once an Account participant begins receiving lifetime annuity income benefits, payment levels cannot be reduced as a result of the Account’s actual mortality experience. In addition, the contracts pursuant to which the Account is offered are required to stipulate the maximum expense charge for all Account level expenses that can be assessed, which is not to exceed 2.5% of average net assets per year. The Account pays a fee to TIAA to assume mortality and expense risks. Accounting for Investments: The investments held by the Account are accounted for as follows: Real Estate Properties —Rent from real estate properties consists of all amounts earned under tenant operating leases, including base rent, recoveries of real estate taxes and other expenses and charges for miscellaneous services provided to tenants. Rental income is recognized in accordance with the billing terms of the lease agreements. The Account bears the direct expenses of the real estate properties owned. These expenses include, but are not limited to, fees to local property management companies, property taxes, utilities, maintenance, repairs, insurance, and other operating and administrative costs. An estimate of the net operating income earned from each real estate property is accrued by the Account on a daily basis and such estimates are adjusted when actual operating results are determined. Real Estate Joint Ventures —The Account has limited ownership interests in various real estate joint ventures (collectively, the “joint ventures”). The Account records its contributions as increases to its investments in the joint ventures, and distributions from the joint ventures are treated as income within income from real estate joint ventures and limited partnerships in the Account’s Consolidated Statements of Operations. Distributions that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas distributions identified as capital gains or losses are recorded as realized gains or losses. Income distributions from the joint ventures are recorded based on the Account’s proportional interest of the income distributed by the joint ventures. Income earned but not yet distributed to the Account by the joint ventures is recorded as unrealized gains and losses. Limited Partnerships —The Account has limited ownership interests in various private real estate funds (primarily limited partnerships) and a private real estate investment trust (collectively, the “limited partnerships”). The Account records its contributions as increases to the investments, and distributions from the investments are treated as income within income from real estate joint ventures and limited partnerships in the Account’s Consolidated Statements of Operations. Distributions that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas distributions identified as capital gains or losses are recorded as realized gains or losses. Unrealized gains and losses are recorded based upon the changes in the net asset values of the limited partnerships as determined from the financial statements of the limited partnerships when received by the Account. Prior to the receipt of the financial statements from the limited partnerships, the Account estimates the value of its interest in good faith and will from time to time seek input from the issuer or the sponsor of the investments. Changes in value based on such estimates are recorded by the Account as unrealized gains and losses. Marketable Securities —Transactions in marketable securities are accounted for as of the date the securities are purchased or sold (trade date). Interest income is recorded as earned. Dividend income is recorded on the ex-dividend date within dividend income. Dividends that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas dividends identified as capital gains or losses are recorded as realized gains or losses. Realized gains and losses on securities transactions are accounted for on the specific identification method. Loans Receivable —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 by TIAA’s internal valuation department with changes in fair value flowing through unrealized gain (loss). Interest income from loans receivable is recognized using the effective interest method over the expected life of the loan. All loans receivable held to date were originated directly by the Account. Realized and Unrealized Gains and Losses —Realized gains and losses are recorded at the time an investment is sold or a distribution is received in relation to an investment sale from a joint venture or limited partnership. Real estate transactions are accounted for as of the date on which the purchase or sale transactions for the real estate properties close (settlement date). The Account recognizes a realized gain on the sale of a real estate property to the extent that the contract sales price exceeds the cost-to-date of the property being sold. A realized loss occurs when the cost-to-date exceeds the sales price. Unrealized gains and losses are recorded as the fair values of the Account’s investments are adjusted, and as discussed within the Real Estate Joint Ventures and Limited Partnerships sections above. Net Assets —The Account’s net assets as of the close of each valuation day are valued by taking the sum of: • the value of the Account’s cash; cash equivalents, and short-term and other debt instruments; • the value of the Account’s other securities and other non-real estate assets; • the value of the individual real properties (based on the most recent valuation of that property) and other real estate-related investments owned by the Account; • an estimate of the net operating income accrued by the Account from its properties, other real estate-related investments and non-real estate-related investments (including short-term marketable securities) since the end of the prior valuation day; and • actual net operating income earned from the Account’s properties, other real estate-related investments and non-real estate-related investments (but only to the extent any such item of income differs from the estimated income accrued for on such investments), and then reducing the sum by liabilities held within the Account, including the daily investment management fee, administration and distribution fees, mortality and expense fee, and liquidity guarantee fee, and certain other 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. After the end of every quarter, the Account reconciles the amount of expenses deducted from the Account (which is established in order to approximate the costs that the Account will incur) with the expenses the Account actually incurred. If there is a difference, the Account adds it to or deducts it from the Account in equal daily installments over the remaining days of the following quarter. Material differences may be repaid in the current calendar quarter. The Account’s 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 the difference between management’s projections and the Account’s actual assets or expenses. Income from Securities Lending: The Account may lend securities to qualified borrowers to generate additional income. When loaning securities, the Account retains the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the securities. Cash collateral received for securities on loan is maintained exclusively in an interest-bearing deposit account. All income generated by the securities lending program is reflected within interest income on the Account's Consolidated Statements of Operations. Cash and Cash Equivalents: Cash and cash equivalents are balances held by the Account in bank deposit accounts which, at times, exceed federally insured limits. The Account’s management monitors these balances to mitigate the exposure of risk due to concentration and has not experienced any losses from such concentration. Other Assets and Other Liabilities: Other assets and other liabilities consist of operating assets and liabilities utilized and held at each individual real estate property investment. Other assets consist of, amongst other items, cash, tenant receivables and prepaid expenses; whereas other liabilities primarily consist of security deposits. Other assets also include cash collateral held for securities on loan. Federal Income Taxes: Based on provisions of the Internal Revenue Code, Section 817, the Account is taxed as a segregated asset account of TIAA and as such, the Account incurs no material federal income tax attributable to the net investment activity of the Account. The Account’s federal income tax return is generally subject to examination for a period of three years after filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed the Account’s tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Account’s Consolidated Financial Statements. The Tax Cuts and Jobs Act (the “Act”) was signed into law on December 22, 2017. The Act changes existing United States tax law and includes numerous provisions that will affect businesses. The Act reduces the U.S. corporate tax rate from 35% to 21%, includes several base broadening provisions, as well as, reform to the US international tax system. The Act does not result in any material impact to the Account. Restricted Cash: The Account held $42.3 million and $45.8 million as of December 31, 2017 and 2016 , respectively, in escrow accounts for property taxes, insurance, and various other property related matters as required by certain creditors related to outstanding mortgage loans payable collateralized by certain real estate investments. These amounts are recorded within Other Assets on the Account's Consolidated Statements of Assets and Liabilities. See Note 8—Mortgage Loans Payable for additional information regarding the Account’s outstanding mortgage loans payable. Changes in Net Assets: Premiums include premiums paid by existing accumulation unit holders in the Account and transfers into the Account. Withdrawals and death benefits include withdrawals out of the Account which include transfers out of the Account and required minimum distributions. Due to/from Investment Manager: Due to/from investment manager represents amounts that are to be paid or received by TIAA on behalf of the Account. Amounts generally are paid or received by the Account within one or two business days and no interest is contractually charged on these amounts. New Accounting Pronouncements: In May 2014, the FASB issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 supersedes all existing revenue recognition guidance and establishes a five-step model to measure and recognize revenue. ASU 2014-09 will be effective for fiscal years beginning after December 15, 2017, the Account will adopt ASU 2014-09 as of January 1, 2018 utilizing the modified retrospective adoption approach. The Account has completed its implementation analysis of ASU 2014-09 and determined it will be immaterially impacted by the adoption. In January 2016, the FASB issued ASU 2016-1 Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-1”). This ASU amends, among other items, certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. These amendments are effective for public business entities for fiscal years and interim periods within those fiscal years beginning after December 15, 2017, and the Account plans to adopt the guidance as of January 1, 2018. Management has completed its initial scoping for the adoption of the ASU 2016-01 and does not expect the guidance to materially impact the Account. In February 2016, the FASB issued ASU 2016-2 Leases (Topic 842) (“ASU 2016-2”) which will supersede Topic 840, Leases. This ASU applies to all entities that enter into a lease. Lessees will be required to report assets and liabilities that arise from leases. Lessor accounting is expected to remain unchanged except in certain circumstances. The ASU also contains certain practical expedients, which the Account plans to elect, including the practical expedient not to separate lease and non-lease components whereby both components are accounted for and recognized as lease components. In January 2018, the FASB issued a proposal for comment that would allow lessors to elect a similar practical expedient by class of underlying assets to not separate non-lease components from the lease component. The Lessor’s practical expedient election would be limited to circumstances in which (i) the timing and pattern of revenue recognition are the same for the non-lease component and the related lease component and (ii) the combined single lease component would be classified as an operating lease. If the exposed practical expedient is issued in its existing form, the Account expects to elect the practical expedient which would allow the Account the ability to combine the lease and non-lease components if the underlying asset meets the two criteria above. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, including all interim periods within those fiscal years. Management has completed its initial scoping for the adoption of the ASU 2016-2 and does not expect the adoption of such guidance to materially impact the Account. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 clarifies how to present cash receipts and cash payments for certain activity in the Statement of Cash Flows. These amendments are effective for public business entities within those fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and should be applied using a retrospective transition method to each period presented. Management has completed its initial scoping for the adoption of the ASU 2016-15 and does not expect the adoption of such guidance to materially impact the Account. The Account plans to adopt the guidance as of January 1, 2018. In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). The statement of cash flows should present beginning-of-period and end-of-period total amounts that include cash and restricted cash. Transfers between cash and restricted cash will no longer be presented as operating activities within the statement of cash flows. ASU 2016-18 is effectiv |

Management Agreements And Arrangements [Abstract] | |
Management Agreements, Arrangements and Related Party Transactions | Management Agreements, Arrangements and Related Party Transactions Investment advisory services for the Account are provided by TIAA employees, under the direction of the Board and its Investment Committee, pursuant to investment management procedures adopted by TIAA for the Account. TIAA’s investment management decisions for the Account are subject to review by the Account’s independent fiduciary. TIAA also provides various portfolio accounting and related services for the Account. The Account is a party to the Distribution Agreement for the Contracts Funded by the TIAA Real Estate Account (the “Distribution Agreement”), dated January 1, 2008, by and among TIAA, for itself and on behalf of the Account, and TIAA-CREF Individual and Institutional Services, LLC (“Services”), a wholly-owned subsidiary of TIAA, a registered broker-dealer and a member of the Financial Industry Regulatory Authority. Pursuant to the Distribution Agreement, Services performs distribution services for the Account which include, among other things, (i) distribution of annuity contracts issued by TIAA and funded by the Account, (ii) advising existing annuity contract owners in connection with their accumulations and (iii) helping employers implement and manage retirement plans. In addition, TIAA performs administrative functions for the Account, which include, among other things, (i) maintaining accounting records and performing accounting services, (ii) receiving and allocating premiums, (iii) calculating and making annuity payments, (iv) processing withdrawal requests, (v) providing regulatory compliance and reporting services, (vi) maintaining the Account’s records of contract ownership and (vii) otherwise assisting generally in all aspects of the Account’s operations. Both distribution services (pursuant to the Distribution Agreement) and administrative services are provided to the Account by Services and TIAA, as applicable, on an at cost basis. The Distribution Agreement is terminable by either party upon 60 days written notice and terminates automatically upon any assignment thereof. TIAA and Services provide investment management, administrative and distribution services at cost. TIAA and Services receive payments from the Account on a daily basis according to formulas established each year and adjusted periodically with the objective of keeping the payments as close as possible to the Account’s expenses actually incurred. Any differences between actual expenses and the amounts paid by the Account are adjusted quarterly. TIAA also provides a liquidity guarantee to the Account, for a fee, to ensure that sufficient funds are available to meet participant transfer and cash withdrawal requests in the event that the Account’s cash flows and liquid investments are insufficient to fund such requests. TIAA ensures sufficient funds are available for such transfer and withdrawal requests by purchasing accumulation units of the Account. In accordance with this liquidity guarantee obligation, TIAA guarantees that all participants in the Account may redeem their accumulation units at their accumulation unit value next determined after their transfer or cash withdrawal request is received in good order. Liquidity units owned by TIAA are valued in the same manner as accumulation units owned by the Account’s participants. Management believes that TIAA has the ability to meet its obligations under the liquidity guarantee. In accordance with a prohibited transaction exemption from the U.S. Department of Labor (PTE 96-76), the Account’s independent fiduciary, RERC, has certain responsibilities with respect to the Account that it has undertaken or is currently undertaking with respect to TIAA’s purchase of liquidity units, including among other things, reviewing the purchase and redemption of liquidity units by TIAA to ensure the Account uses the correct unit values. In addition, as set forth in PTE 96-76, the independent fiduciary’s responsibilities include: • establishing the percentage of total accumulation units that TIAA’s ownership should not exceed (the “trigger point”) and creating a method for changing the trigger point; • approving any adjustment of TIAA’s ownership interest in the Account and, in its discretion, requiring an adjustment if TIAA’s ownership of liquidity units reaches the trigger point; and • once the trigger point has been reached, participating in any program to reduce TIAA’s ownership in the Account by utilizing cash flow or liquid investments in the Account, or by utilizing the proceeds from asset sales. The independent fiduciary’s role in participating in any such asset sales program would include (i) participating in the selection of properties for sale, (ii) providing sales guidelines and (iii) approving those sales if, in the independent fiduciary’s opinion, such sales are desirable to reduce TIAA’s ownership of liquidity units. To the extent TIAA owns accumulation units issued pursuant to the liquidity guarantee, the independent fiduciary monitors and oversees, among other things, TIAA’s ownership interest in the Account and may require TIAA to eventually redeem some of its units, particularly when the Account has un-invested cash or liquid investments available. TIAA also receives a fee for assuming certain mortality and expense risks. The independent fiduciary, which has the right to adjust the trigger point, has established the trigger point at 45% of the outstanding accumulation units and it will continue to monitor TIAA’s ownership interest in the Account and provide further recommendations as necessary. TIAA and Services provide certain services to the Account on an at cost basis. See Note 9—Financial Highlights for details of the expense charge and expense ratio. |

Risks and Uncertainties [Abstract] | |
Credit Risk Concentrations | Credit Risk Concentrations Concentrations of credit risk may arise when a number of properties or tenants are located in a similar geographic region such that the economic conditions of that region could impact tenants’ obligations to meet their contractual obligations or cause the values of individual properties to decline. The Account has no significant concentrations of tenants as no single tenant has annual contract rent that makes up more than 2% of the rental income of the Account. The Account’s wholly-owned real estate investments and investments in joint ventures are located in the United States.

Fair Value Disclosures [Abstract] | |
Assets and Liabilities Measured at Fair Value on a Recurring Basis | Assets and Liabilities Measured at Fair Value on a Recurring Basis Valuation Hierarchy: The Account’s fair value measurements are grouped categorically into three levels, as defined by the FASB. The levels are defined as follows: Level 1—Valuations using unadjusted quoted prices for assets traded in active markets, such as stocks listed on the New York Stock Exchange. Active markets are defined as having the following characteristics for the measured asset or liability: (i) many transactions, (ii) current prices, (iii) price quotes not varying substantially among market makers, (iv) narrow bid/ask spreads and (v) most information regarding the issuer is publicly available. Level 1 assets held by the Account are generally marketable equity securities. Level 2—Valuations for assets and liabilities traded in less active, dealer or broker markets. Fair values are primarily obtained from third party pricing services for identical or comparable assets or liabilities. Level 2 inputs for fair value measurements are inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: a. Quoted prices for similar assets or liabilities in active markets; b. Quoted prices for identical or similar assets or liabilities in markets that are not active (that is, markets in which there are few transactions for the asset (or liability), the prices are not current, price quotations vary substantially either over time or among market makers (for example, some brokered markets), or in which little information is released publicly); c. Inputs other than quoted prices that are observable within the market for the asset (or liability) (for example, interest rates and yield curves, implied volatilities, prepayment speeds, loss severities, credit risks, and default rates that are observable at commonly quoted intervals); and d. Inputs that are derived principally from or corroborated by observable market data by correlation or other means (for example, market-corroborated inputs). Examples of securities which may be held by the Account and included in Level 2 include certificates of deposit, commercial paper, government agency notes, variable notes, United States Treasury securities, and debt securities. Level 3—Valuations for assets and liabilities that are derived from other valuation methodologies, including pricing models, discounted cash flow models and similar techniques, and are not based on market exchange, dealer, or broker-traded transactions. Level 3 valuations incorporate certain assumptions and projections that are not observable in the market, and require significant professional judgment in determining the fair value assigned to such assets or liabilities. Examples of Level 3 assets and liabilities which may be held by the Account from time to time include investments in real estate, investments in joint ventures, and loans receivable and payable. An investment’s categorization within the valuation hierarchy described above is based upon the lowest level of input that is significant to the fair value measurement. The Account’s limited partnership investments are valued using the net asset value per share as a practical expedient, which excludes the investments from the valuation hierarchy. The Account’s determination of fair value is based upon quoted market prices, where available. If listed prices or quotes 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 will be made to reflect changes in credit quality, counterparty’s creditworthiness, the Account’s creditworthiness, liquidity, and other observable and unobservable inputs that are applied consistently over time. The methods described above are considered to produce fair values that represent a good faith estimate of what an unaffiliated buyer in the marketplace would pay to purchase the asset or would 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. As discussed in Note 1 — Organization and Significant Accounting Policies in more detail, the Account generally obtains independent third party appraisals on a quarterly basis; there may be circumstances in the interim 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. The following tables show the major categories of assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 and 2016 , using unadjusted quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); significant unobservable inputs (Level 3); and Practical Expedient (in millions): Description Level 1: Quoted Prices in Active Markets for Identical Assets Level 2: Significant Other Observable Inputs Level 3: Significant Unobservable Inputs Fair Value Using Practical Expedient Total at December 31, 2017 Real estate properties $ — $ — $ 15,742.7 $ — $ 15,742.7 Real estate joint ventures — — 5,860.6 — 5,860.6 Limited partnerships — — — 142.4 142.4 Marketable securities: Real estate-related 1,238.0 — — — 1,238.0 Government agency notes — 2,872.3 — — 2,872.3 United States Treasury securities — 1,015.2 — — 1,015.2 Loans receivable — — 298.8 — 298.8 Total Investments at $ 1,238.0 $ 3,887.5 $ 21,902.1 $ 142.4 $ 27,170.0 Mortgage loans payable $ — $ — $ (2,238.3 ) $ — $ (2,238.3 ) Description Level 1: Quoted Prices in Active Markets for Identical Assets Level 2: Significant Other Observable Inputs Level 3: Significant Unobservable Inputs Fair Value Using Practical Expedient Total at December 31, 2016 Real estate properties $ — $ — $ 15,452.8 $ — $ 15,452.8 Real estate joint ventures — — 5,622.4 — 5,622.4 Limited partnerships — — — 137.5 137.5 Marketable securities: Real estate-related 1,081.5 — — — 1,081.5 Government agency notes — 2,308.9 — — 2,308.9 United States Treasury securities — 1,744.9 — — 1,744.9 Loans receivable — — 295.7 — 295.7 Total Investments at $ 1,081.5 $ 4,053.8 $ 21,370.9 $ 137.5 $ 26,643.7 Mortgage loans payable $ — $ — $ (2,332.1 ) $ — $ (2,332.1 ) The following tables show the reconciliation of the beginning and ending balances for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the years ended December 31, 2017 and 2016 (in millions): Real Estate Properties Real Estate Joint Ventures Loans Receivable Total Level 3 Investments Mortgage Loans Payable For the year ended December 31, 2017 Beginning balance January 1, 2017 $ 15,452.8 $ 5,622.4 $ 295.7 $ 21,370.9 $ (2,332.1 ) Total realized and unrealized gains included in changes in net assets 177.5 123.5 1.2 302.2 15.9 Purchases (1) 682.9 419.0 1.9 1,103.8 (17.7 ) Sales (570.5 ) — — (570.5 ) — Settlements (2) — (304.3 ) — (304.3 ) 95.6 Ending balance December 31, 2017 $ 15,742.7 $ 5,860.6 $ 298.8 $ 21,902.1 $ (2,238.3 ) Real Estate Properties Real Estate Joint Ventures Loans Receivable Total Level 3 Investments Mortgage Loans Payable For the year ended December 31, 2016 Beginning balance January 1, 2016 $ 14,606.2 $ 4,068.4 $ 100.6 $ 18,775.2 $ (1,794.4 ) Total realized and unrealized gains included in changes in net assets 311.3 242.8 0.3 554.4 15.1 Purchases (1) 786.4 1,313.6 194.8 2,294.8 (587.5 ) Sales (251.1 ) — — (251.1 ) — Settlements (2) — (2.4 ) — (2.4 ) 34.7 Ending balance December 31, 2016 $ 15,452.8 $ 5,622.4 $ 295.7 $ 21,370.9 $ (2,332.1 ) (1) Includes purchases, contributions for joint ventures, capital expenditures, lending for loans receivable and assumption of mortgage loans payable.

Significant increases (decreases) in any of those inputs in isolation would result in significantly lower (higher) fair value measurements, respectively. Mortgage Loans Payable: The significant unobservable inputs used in the fair value measurement of the Account’s mortgage loans payable are the loan-to-value ratios and the selection of certain credit spreads and weighted average cost of capital risk premiums. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value, respectively. Loans Receivable: The significant unobservable inputs used in the fair value measurement of the Account’s loans receivable are the loan-to-value ratios and the selection of certain credit spreads.

Securities Lending | Securities Lending The Account may lend securities to qualified borrowers to earn additional income. The Account receives cash collateral against the loaned securities and maintains cash collateral in an amount not less than 100% of the market value of loaned securities during the period of the loan; any additional collateral required due to changes in security values is delivered to the Account the next business day. Cash collateral received by the Account is invested exclusively in an interest-bearing deposit account. The value of the loaned securities and the liability to return the cash collateral received are reflected in the Account's Consolidated Statements of Assets and Liabilities. As of December 31, 2017, securities lending transactions are for real-estate related equity securities, and the resulting loans are continuous, can be recalled at any time, and have no set maturity. Securities lending income recognized by the Account consists of interest earned on cash collateral and lending fees, net of any rebates to the borrower and compensation to the agent. Such income is reflected within interest income on the Account's Consolidated Statements of Operations. In lending its securities, the Account bears the market risk with respect to the investment of collateral and the risk that the agent may default on its contractual obligations to the Account. The 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 loan securities have not been returned. |

Total return is computed based on the AUV used for processing transactions. |
Determination of Investments at Fair Value | Determination of Investments at Fair Value: The Account reports all investments at fair value in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. Further in accordance with the adoption of the fair value option allowed under ASC 825, Financial Instruments , and at the election of Account management, mortgage loans payable are reported at fair value. The FASB has defined fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The following is a description of the valuation methodologies used to determine the fair value of the Account’s investments and investment related mortgage loans payable. Valuation of Real Estate Properties —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. Determination of fair value involves significant levels of judgment because the actual fair value of real estate can be determined only by negotiation between the parties in a sales transaction. The Account’s primary objective when valuing its real estate investments will be to produce a valuation that represents a reasonable estimate of the fair value of its investments. Implicit in the Account’s definition of fair value are the consummation of a sale as of a specified date and the passing of title from seller to buyer under conditions whereby: • Buyer and seller are typically motivated; • Both parties are well informed or well advised, and acting in what they consider their best interests; • A reasonable time is allowed for exposure in the open market; • Payment is made in terms of cash or in terms of financial arrangements comparable thereto; and • The price represents the normal consideration for the property sold unaffected by special or creative financing or sales concessions granted by anyone associated with the sale. 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. Key inputs and assumptions include rental income and expense amounts, related rental income and expense growth rates, capital expenditures, discount rates and capitalization rates. Valuation techniques include discounted cash flow analysis, prevailing market capitalization rates or multiples applied to earnings from the property, analysis of recent comparable sales transactions, actual sale negotiations and bona fide purchase offers received from third parties. Amounts ultimately realized from each investment may vary significantly from the fair value presented. Real estate properties owned by the Account are initially valued based on an independent third party appraisal, as reviewed by TIAA’s internal appraisal staff and as applicable by the Account’s independent fiduciary at the time of the closing of the purchase. Such initial valuation 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 is appraised each quarter by an independent third party appraiser, reviewed by TIAA’s internal appraisal staff and as applicable the Account’s independent fiduciary. 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 such adjustments are made) that happen regularly throughout each quarter and not on one specific day or month in each period. 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 the account receives a bona fide bid for the sale of a property held within the Account or one of the Account’s joint ventures. 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). Alternatively, adjustments may be made to reflect the execution or renewal of a significant lease. 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. TIAA’s internal appraisal staff oversees the entire appraisal process, in conjunction with the Account’s independent fiduciary (the independent fiduciary is more fully described in the following paragraph). 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). The independent fiduciary, RERC, LLC, has been appointed by a special subcommittee of the Investment Committee of the Board to, among other things, oversee the appraisal process. The independent fiduciary must approve all independent appraisers used by the Account. All appraisals are performed in accordance with Uniform Standards of Professional Appraisal Practices, the real estate appraisal industry standards created by The Appraisal Foundation. Real estate appraisals are estimates of property values based on a professional’s opinion. Appraisals of properties held outside of the U.S. are performed in accordance with industry standards commonly applied in the applicable jurisdiction. These independent appraisers 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. Also, the independent fiduciary can require additional appraisals if factors or events have occurred that could materially change a property’s value (including those identified above) and such change is not reflected in the quarterly valuation review, or otherwise to ensure that the Account is valued appropriately. The independent fiduciary must also approve any valuation change of real estate-related assets where a property’s value changed by more than 6% from the most recent independent annual appraisal, or if the value of the Account would change by more than 4% within any calendar quarter or more than 2% since the prior calendar month. When a real estate property is subject to a mortgage, the property is valued independently of the mortgage and the property and mortgage fair values are reported separately (see Valuation of Mortgage Loans Payable ). The independent fiduciary reviews and approves all mortgage valuation adjustments before such adjustments are recorded by the Account. The Account continues 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. Valuation of Real Estate Joint Ventures —Real estate joint ventures are stated at the fair value of the Account’s ownership interests of 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. 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. Valuation of Real Estate Limited Partnerships —Limited partnership interests are stated at the fair value of the Account’s ownership in the partnership which are recorded based upon the changes in the net asset values of the limited partnerships as determined from the financial statements of the limited partnerships when received by the Account. Prior to the receipt of the financial statements from the limited partnerships, the Account estimates the value of its interest in good faith and will from time to time seek input from the issuer or the sponsor of the investments. Since market quotations are not readily available, the limited partnership interests are valued at fair value as determined in good faith by management under the direction of the Investment Committee of the Board and in accordance with the responsibilities of the Board as a whole. Valuation of Marketable Securities —Equity securities listed or traded on any national market or exchange are valued at the last sale price as of the close of the principal securities market or exchange on which such securities are traded or, if there is no sale, at the mean of the last bid and asked prices on such market or exchange, exclusive of transaction costs. Debt securities with readily available market quotations, other than money market instruments, are generally valued at the most recent bid price or the equivalent quoted yield for such securities (or those of comparable maturity, quality and type). 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 are valued in the same manner as debt securities, as described above. Money market instruments are valued at amortized cost, which approximates fair value. Equity and fixed income securities traded on a foreign exchange or in foreign markets are valued using their closing values under the valuation methods generally accepted in the country where traded, as of the valuation date. This value is converted 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 U.S. 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. Valuation of 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 by TIAA’s internal valuation department 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 (such as the loan-to-value ratio and the cash flow of the underlying collateral) and the credit quality of the counterparty. The independent fiduciary reviews and approves all loan receivable valuation adjustments before such adjustments are recorded by the Account. The Account continues to use the revised value for each loan receivable to calculate the Account’s daily net asset value until the next valuation review. Loan origination costs are expensed as incurred. Valuation of Mortgage Loans Payable (i.e. the Account as a debtor) —Mortgage loans payable are stated at fair value. The estimated fair values of mortgage loans payable are based on the amount at which the liability could be transferred to a third party exclusive of transaction costs. Mortgage loans payable are valued internally by TIAA’s internal valuation department, as reviewed by the Account’s independent fiduciary, at least quarterly based on market factors, such as market interest rates and spreads for comparable loans, the performance of the underlying collateral (such as the loan-to-value ratio and the cash flow of the underlying collateral), the liquidity for mortgage loans of similar characteristics, the maturity date of the loan and the return demands of the market. |
Foreign Currency Transactions and Translation | Foreign Currency Transactions and Translation: Portfolio investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of securities, income receipts and expense payments made in foreign currencies are translated into U.S. dollars at the exchange rates prevailing on the respective dates of the transactions. The effect of any changes in foreign currency exchange rates on portfolio investments and mortgage loans payable are included in net realized and unrealized gains and losses on real estate properties and mortgage loans payable. Net realized gains and losses on foreign currency transactions include disposition of foreign currencies, and currency gains and losses between the accrual and receipt dates of portfolio investment income and between the trade and settlement dates of portfolio investment transactions. |
Accumulation and Annuity Funds | Accumulation and Annuity Funds: The accumulation fund represents the net assets attributable to participants in the accumulation phase of their investment (“Accumulation Fund”). The annuity fund represents the net assets attributable to the participants currently receiving annuity payments (“Annuity Fund”). The net increase or decrease in net assets from investment operations is apportioned between the accounts based upon their relative daily net asset values. Once an Account participant begins receiving lifetime annuity income benefits, payment levels cannot be reduced as a result of the Account’s actual mortality experience. In addition, the contracts pursuant to which the Account is offered are required to stipulate the maximum expense charge for all Account level expenses that can be assessed, which is not to exceed 2.5% of average net assets per year. The Account pays a fee to TIAA to assume mortality and expense risks. |
Accounting for Investments | Accounting for Investments: The investments held by the Account are accounted for as follows: Real Estate Properties —Rent from real estate properties consists of all amounts earned under tenant operating leases, including base rent, recoveries of real estate taxes and other expenses and charges for miscellaneous services provided to tenants. Rental income is recognized in accordance with the billing terms of the lease agreements. The Account bears the direct expenses of the real estate properties owned. These expenses include, but are not limited to, fees to local property management companies, property taxes, utilities, maintenance, repairs, insurance, and other operating and administrative costs. An estimate of the net operating income earned from each real estate property is accrued by the Account on a daily basis and such estimates are adjusted when actual operating results are determined. Real Estate Joint Ventures —The Account has limited ownership interests in various real estate joint ventures (collectively, the “joint ventures”). The Account records its contributions as increases to its investments in the joint ventures, and distributions from the joint ventures are treated as income within income from real estate joint ventures and limited partnerships in the Account’s Consolidated Statements of Operations. Distributions that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas distributions identified as capital gains or losses are recorded as realized gains or losses. Income distributions from the joint ventures are recorded based on the Account’s proportional interest of the income distributed by the joint ventures. Income earned but not yet distributed to the Account by the joint ventures is recorded as unrealized gains and losses. Limited Partnerships —The Account has limited ownership interests in various private real estate funds (primarily limited partnerships) and a private real estate investment trust (collectively, the “limited partnerships”). The Account records its contributions as increases to the investments, and distributions from the investments are treated as income within income from real estate joint ventures and limited partnerships in the Account’s Consolidated Statements of Operations. Distributions that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas distributions identified as capital gains or losses are recorded as realized gains or losses. Unrealized gains and losses are recorded based upon the changes in the net asset values of the limited partnerships as determined from the financial statements of the limited partnerships when received by the Account. Prior to the receipt of the financial statements from the limited partnerships, the Account estimates the value of its interest in good faith and will from time to time seek input from the issuer or the sponsor of the investments. Changes in value based on such estimates are recorded by the Account as unrealized gains and losses. Marketable Securities —Transactions in marketable securities are accounted for as of the date the securities are purchased or sold (trade date). Interest income is recorded as earned. Dividend income is recorded on the ex-dividend date within dividend income. Dividends that are identified as returns of capital are recorded as a reduction to the cost basis of the investment, whereas dividends identified as capital gains or losses are recorded as realized gains or losses. Realized gains and losses on securities transactions are accounted for on the specific identification method. Loans Receivable —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 by TIAA’s internal valuation department with changes in fair value flowing through unrealized gain (loss). Interest income from loans receivable is recognized using the effective interest method over the expected life of the loan. All loans receivable held to date were originated directly by the Account. Realized and Unrealized Gains and Losses —Realized gains and losses are recorded at the time an investment is sold or a distribution is received in relation to an investment sale from a joint venture or limited partnership. Real estate transactions are accounted for as of the date on which the purchase or sale transactions for the real estate properties close (settlement date). The Account recognizes a realized gain on the sale of a real estate property to the extent that the contract sales price exceeds the cost-to-date of the property being sold. A realized loss occurs when the cost-to-date exceeds the sales price. Unrealized gains and losses are recorded as the fair values of the Account’s investments are adjusted, and as discussed within the Real Estate Joint Ventures and Limited Partnerships sections above. Net Assets —The Account’s net assets as of the close of each valuation day are valued by taking the sum of: • the value of the Account’s cash; cash equivalents, and short-term and other debt instruments; • the value of the Account’s other securities and other non-real estate assets; • the value of the individual real properties (based on the most recent valuation of that property) and other real estate-related investments owned by the Account; • an estimate of the net operating income accrued by the Account from its properties, other real estate-related investments and non-real estate-related investments (including short-term marketable securities) since the end of the prior valuation day; and • actual net operating income earned from the Account’s properties, other real estate-related investments and non-real estate-related investments (but only to the extent any such item of income differs from the estimated income accrued for on such investments), and then reducing the sum by liabilities held within the Account, including the daily investment management fee, administration and distribution fees, mortality and expense fee, and liquidity guarantee fee, and certain other 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. After the end of every quarter, the Account reconciles the amount of expenses deducted from the Account (which is established in order to approximate the costs that the Account will incur) with the expenses the Account actually incurred. If there is a difference, the Account adds it to or deducts it from the Account in equal daily installments over the remaining days of the following quarter. Material differences may be repaid in the current calendar quarter. The Account’s 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 the difference between management’s projections and the Account’s actual assets or expenses. |
Income from Securities Lending | Income from Securities Lending: The Account may lend securities to qualified borrowers to generate additional income. When loaning securities, the Account retains the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the securities. Cash collateral received for securities on loan is maintained exclusively in an interest-bearing deposit account. All income generated by the securities lending program is reflected within interest income on the Account's Consolidated Statements of Operations. |
Cash and Cash Equivalents | Cash and Cash Equivalents: Cash and cash equivalents are balances held by the Account in bank deposit accounts which, at times, exceed federally insured limits. The Account’s management monitors these balances to mitigate the exposure of risk due to concentration and has not experienced any losses from such concentration. |
Other Assets and Other Liabilities | Other Assets and Other Liabilities: Other assets and other liabilities consist of operating assets and liabilities utilized and held at each individual real estate property investment. Other assets consist of, amongst other items, cash, tenant receivables and prepaid expenses; whereas other liabilities primarily consist of security deposits. Other assets also include cash collateral held for securities on loan. |
Federal Income Taxes | Federal Income Taxes: Based on provisions of the Internal Revenue Code, Section 817, the Account is taxed as a segregated asset account of TIAA and as such, the Account incurs no material federal income tax attributable to the net investment activity of the Account. The Account’s federal income tax return is generally subject to examination for a period of three years after filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed the Account’s tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Account’s Consolidated Financial Statements. |
Restricted Cash | Restricted Cash: The Account held $42.3 million and $45.8 million as of December 31, 2017 and 2016 , respectively, in escrow accounts for property taxes, insurance, and various other property related matters as required by certain creditors related to outstanding mortgage loans payable collateralized by certain real estate investments. These amounts are recorded within Other Assets on the Account's Consolidated Statements of Assets and Liabilities. |
Changes In Net Assets | Changes in Net Assets: Premiums include premiums paid by existing accumulation unit holders in the Account and transfers into the Account. Withdrawals and death benefits include withdrawals out of the Account which include transfers out of the Account and required minimum distributions. |
Due to/from Investment Manager | Due to/from Investment Manager: Due to/from investment manager represents amounts that are to be paid or received by TIAA on behalf of the Account. Amounts generally are paid or received by the Account within one or two business days and no interest is contractually charged on these amounts. |
New Accounting Pronouncement | New Accounting Pronouncements: In May 2014, the FASB issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 supersedes all existing revenue recognition guidance and establishes a five-step model to measure and recognize revenue. ASU 2014-09 will be effective for fiscal years beginning after December 15, 2017, the Account will adopt ASU 2014-09 as of January 1, 2018 utilizing the modified retrospective adoption approach. The Account has completed its implementation analysis of ASU 2014-09 and determined it will be immaterially impacted by the adoption. In January 2016, the FASB issued ASU 2016-1 Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-1”). This ASU amends, among other items, certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. These amendments are effective for public business entities for fiscal years and interim periods within those fiscal years beginning after December 15, 2017, and the Account plans to adopt the guidance as of January 1, 2018. Management has completed its initial scoping for the adoption of the ASU 2016-01 and does not expect the guidance to materially impact the Account. In February 2016, the FASB issued ASU 2016-2 Leases (Topic 842) (“ASU 2016-2”) which will supersede Topic 840, Leases. This ASU applies to all entities that enter into a lease. Lessees will be required to report assets and liabilities that arise from leases. Lessor accounting is expected to remain unchanged except in certain circumstances. The ASU also contains certain practical expedients, which the Account plans to elect, including the practical expedient not to separate lease and non-lease components whereby both components are accounted for and recognized as lease components. In January 2018, the FASB issued a proposal for comment that would allow lessors to elect a similar practical expedient by class of underlying assets to not separate non-lease components from the lease component. The Lessor’s practical expedient election would be limited to circumstances in which (i) the timing and pattern of revenue recognition are the same for the non-lease component and the related lease component and (ii) the combined single lease component would be classified as an operating lease. If the exposed practical expedient is issued in its existing form, the Account expects to elect the practical expedient which would allow the Account the ability to combine the lease and non-lease components if the underlying asset meets the two criteria above. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, including all interim periods within those fiscal years. Management has completed its initial scoping for the adoption of the ASU 2016-2 and does not expect the adoption of such guidance to materially impact the Account. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 clarifies how to present cash receipts and cash payments for certain activity in the Statement of Cash Flows. These amendments are effective for public business entities within those fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and should be applied using a retrospective transition method to each period presented. Management has completed its initial scoping for the adoption of the ASU 2016-15 and does not expect the adoption of such guidance to materially impact the Account. The Account plans to adopt the guidance as of January 1, 2018. In November 2016, the FASB issued Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). The statement of cash flows should present beginning-of-period and end-of-period total amounts that include cash and restricted cash. Transfers between cash and restricted cash will no longer be presented as operating activities within the statement of cash flows. ASU 2016-18 is effective for annual financial statements issued for fiscal years beginning after December 15, 2017 and should be applied using a retrospective transition method to each period presented. Management expects that the impact of ASU 2016-18 will require modification to the presentation of restricted cash on the Account's Consolidated Statements of Cash Flows. The Account plans to adopt the guidance as of January 1, 2018. In January 2017, the FASB issued Accounting Standard Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 provides guidance for evaluating whether a set of transferred assets and activities is a business, which may result in certain real estate acquisitions being accounted for as asset acquisitions rather than business combinations. ASU 2017-01 will be effective for fiscal years beginning after December 15, 2017, however, this guidance will not impact the Account. In March 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. The amendments in ASU 2017-05 clarify the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales. ASU 2017-05 is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments may be either retrospectively applied to each period presented within the financial statements or by a cumulative-effect adjustment to retained earnings or net assets as of the beginning of the fiscal year of adoption. The Account will elect the modified retrospective approach upon adoption. Management has completed its initial scoping for the adoption of the ASU 2017-05 and does not expect the guidance to materially impact the Account. The Account plans to adopt the guidance as of January 1, 2018. |

Description of valuation change of real estate related assets | Also, the independent fiduciary can require additional appraisals if factors or events have occurred that could materially change a property’s value (including those identified above) and such change is not reflected in the quarterly valuation review, or otherwise to ensure that the Account is valued appropriately. The independent fiduciary must also approve any valuation change of real estate-related assets where a property’s value changed by more than 6% from the most recent independent annual appraisal, or if the value of the Account would change by more than 4% within any calendar quarter or more than 2% since the prior calendar month. When a real estate property is subject to a mortgage, the property is valued independently of the mortgage and the property and mortgage fair values are reported separately (see Valuation of Mortgage Loans Payable). The independent fiduciary reviews and approves all mortgage valuation adjustments before such adjustments are recorded by the Account. The Account continues 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. | |
