NOTE 3—REAL ESTATE

Effective January 1, 2014, we acquired a controlling interest in The Grove at Shrewsbury, a 187,000 square foot shopping center in Shrewsbury, New Jersey, and Brook 35, a 99,000 square foot shopping center in Sea Girt, New Jersey for a gross value of $161 million. Our effective economic interest approximates 84% and was funded by the assumption of our share of $68 million of mortgage debt, 632,000 downREIT operating partnership units, and $13 million of cash (which was in an escrow account at December 31, 2013). Approximately $1.7 million and $2.3 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases," respectively. Additionally, $71.1 million was allocated to redeemable and nonredeemable noncontrolling interests. We incurred $2.0 million of acquisition costs, of which $0.9 million were incurred in 2014 and included in "general and administrative expense" for the six months ended June 30, 2014.

We have entered into an agreement to acquire the interest of one of the noncontrolling interest holders in The Grove at Shrewsbury in 2015. As this noncontrolling interest is mandatorily redeemable, it has been classified as a liability of approximately $9 million and is included in "other liabilities and deferred credits" on the June 30, 2014 consolidated balance sheet. An additional noncontrolling interest holder has the right to require us to acquire its interests in The Grove at Shrewsbury and Brook 35 at the then current fair market value beginning on January 1, 2017.
