[2] | Real estate is valued using the NAV per unit of funds that are invested in real estate property. The investment value of the real estate property is determined quarterly using independent market appraisals as determined by the investment manager. Since the appraisals include unobservable inputs, these investments are classified as Level 3. These unobservable inputs may include items such as annual gross rents, projected vacancy rates, collection losses and recovery rates, yield rates, growth assumptions and risk adjusted discount rates. |
