(1)	Effective weighted average interest rate for the quarter ended June 30, 2016, taking into account interest rate hedges in effect during the period.


(2)	In February 2016, we closed on the sale of 885 Third Avenue. The sale did not meet the criteria for sale accounting and as a result the property remains on our consolidated balance sheet until the criteria is met.


(3)	We own a 51.0% controlling interest in the consolidated joint venture that is the borrower on this loan.

In connection with the acquisition of a commercial real estate property, the Operating Partnership issued $4.0 million, 3.75% Series J Preferred Units of limited partnership interest, or the Series J Preferred Units, with a mandatory liquidation preference of $1,000.00 per unit. The Series J Preferred Units are accounted for as debt because they can be redeemed in cash by the Operating Partnership on the earlier of (i) the date of the sale of the property or (ii) April 30, 2051 or at the option of the unitholders as provided for in the related agreement.
