⁽¹⁾: Effective average interest rate for the year ended December 31, 2012.
⁽²⁾: We own a 51% controlling interest in the joint venture that is the borrower on this loan. This loan is non-recourse to us. In June 2011, our joint venture replaced the $219.9 million 6.87% mortgage that was due to mature in August 2011 with a $500.0 million mortgage.
⁽³⁾: This loan is secured by a portion of a preferred equity investment.
⁽⁴⁾: We increased this loan by $40.0 million in March 2011.
⁽⁵⁾: As part of an acquisition, we issued 63.9 million units of our 5.0% Series E preferred units, or the Series E units, with a liquidation preference of $1.00 per unit. As of December 31, 2012, 63.8 million Series E units had been redeemed.
⁽⁶⁾: We acquired the remaining interest in this joint venture in April 2011. As a result, we have consolidated this investment since April 2011. In April 2012, we refinanced the $447.2 million mortgage that was due in December 2014 with a $775.0 million 7-year mortgage which carries interest at the rate equal to the greater of (a) 285 basis points over 90-day LIBOR or (b) 3.6% per annum.
⁽⁷⁾: In connection with this consolidated joint venture obligation, we executed a master lease agreement. Our partner has executed a contribution agreement to reflect its pro rata share of the obligation under the master lease.
⁽⁸⁾: This loan, which was denominated in British pounds, bore interest at 250 basis points over the three-month GBP LIBOR. In November 2012, this loan was repaid in connection with the sale of the London property.
⁽⁹⁾: We assumed a $140.0 million mortgage in connection with the acquisition of the remaining partnership interest in January 2011. As a result, we consolidated this investment since January 2011. In April 2011, we refinanced the property with a new $150.0 million 2-year mortgage which carried a floating rate of interest of 200 basis points over the 30-day LIBOR. In November 2012, we sold 49.5% of our partnership interest in 521 Fifth Avenue and refinanced the property with a new $170.0 million 7-year mortgage which bears interest at 220 basis points over LIBOR. As we no longer controlled the entity, we deconsolidated this entity effective November 30, 2012 and accounted for our investment under the equity method. See Note 6, "Investments in Unconsolidated Joint Ventures."
⁽¹⁰⁾: In December 2012, we repaid the $93.3 million mortgage loan, which bore interest at a fixed rate of 5.85% per annum and was scheduled to mature in October 2013. We recognized a loss from early extinguishment of debt of approximately $3.1 million consisting mainly of prepayment penalty.

⁽¹²⁾: We took control of this property in May 2011 and assumed the mortgage as part of the transaction. This loan consists of a $65.0 million A-tranche and an $18.1 million B-tranche which was owed to us. The B-tranche does not accrue interest and is due only under certain circumstances as described in the loan agreement. In December 2012, we repaid the $65.0 million mortgage loan, which bore interest at a fixed rate of 5.81% per annum and was scheduled to mature in July 2017. There was no prepayment penalty.
⁽¹³⁾: This property was sold in February 2012 and the related mortgage, which was included in liabilities related to assets held for sale at December 31, 2011, was assumed by the purchaser.
⁽¹⁴⁾: In September 2012, we entered into a Master Repurchase Agreement, or MRA, with a financial institution, with a maximum facility capacity of $175.0 million, under which we agreed to sell certain debt investments in exchange for cash with a simultaneous agreement to repurchase the same debt investments at a certain date or on demand. The MRA's interest rate is based on 1-month LIBOR plus 300 basis points. The MRA matures in September 2013, and has a 1-year extension option.
