[1] Invested in the Russell Real Estate Equity Fund. Real estate investments include those in limited partnerships that invest in various domestic commercial and residential real estate projects. The fair values of real estate assets are typically determined by using income and/or cost approaches or a comparable sales approach, taking into consideration discount and capitalization rates, financial conditions, local market conditions, and the status of the capital markets, and they are thus classified within Level 3. Notwithstanding the above, the variety of valuation bases adopted and quality of management data of the underlying assets means that there are inherent difficulties in determining the value of the investments. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date.
