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

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

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

Alternatively, periods of significant net transfer activity into the Account can result in the Account holding a higher percentage of its net assets in publicly traded liquid non-real estate-related investments than the Account’s managers would target to hold under the Account’s long-term strategy.
