Redeemable partnership units on our consolidated balance sheets represent Class A units held by third parties and are comprised of Class A units not held by Vornado and Series D-10, D-11, D-14, D-15 and D-16 (collectively, “Series D”) cumulative redeemable preferred units. Redeemable partnership units on our consolidated balance sheets are recorded at the greater of their carrying amount or redemption value at the end of each reporting period. Changes in the value from period to period are charged to “partners' capital” on our consolidated balance sheet. Below is a table summarizing the activity of redeemable partnership units.

As of June 30, 2011 and December 31, 2010, the aggregate redemption value of redeemable Class A units, which are those units held by third parties, was $1,170,467,000 and $1,066,974,000, respectively.

Redeemable partnership units exclude our Series G-1 through G-4 convertible preferred units and Series D-13 cumulative redeemable preferred units, as they are accounted for as liabilities in accordance with ASC 480, Distinguishing Liabilities and Equity, because of their possible settlement by issuing a variable number of Vornado common shares. Accordingly the fair value of these units is included as a component of “other liabilities” on our consolidated balance sheets and aggregated $55,097,000 as of June 30, 2011 and December 31, 2010.

In June 2011, we redeemed 400,000 Series D-11 cumulative redeemable preferred units for $8,000,000 in cash. In March and May of 2010, we redeemed 246,153 and 553,847 Series D-12 cumulative redeemable preferred units, respectively, for an aggregate of $13,000,000 in cash.
