[1] Amount represents the step-up in basis to the estimated fair value of the assets received as of the date of acquisition based on appraisals received for such assets. The stepped up basis reflects the approximate balances of certain liabilities assumed upon foreclosure including a mortgage note payable of approximately $24.7 million, a capital lease obligation of approximately $1.3 million, and accounts payable and accrued liabilities of $3.4 million at the date of acquisition. The appraised values of such assets were equal to or in excess of the new assets recorded.
