The properties had an estimated fair value of $89.3 million on the transfer date. Upon completion of this transfer, we recognized a gain on extinguishment of debt of $36.5 million, representing the difference between the loan and accrued interest payable extinguished over the carrying value of the properties, cash, accounts payable and accounts receivable transferred as of the transfer date and related closing costs.
[5] | The properties included in this portfolio disposition are: Corporate Center West, Farnam Executive Center, Flagship Corporate Center, Gateway Corporate Center, Miracle Hills One, Pacific Hills, Riverport, Timberlands, and Woodlands Plaza IV.
