[1] | The fair value of 717 N. Michigan Avenue was based on an observable contract to sell the asset, less estimated costs to sell. The Company estimated the fair value of 146 Geary Street based on a discounted cash flow analysis using a range of discount rates from 5.00% to 7.75% and a range of capitalization rates from 4.25% to 5.75%. As significant inputs to the models are unobservable, the Company determined that the value determined for these properties falls within Level 3 of the fair value reporting hierarchy.
