[1] As of March 31, 2015, the Company had Class B membership interests in The Grove at Indiana, Pennsylvania, The Grove at Greensboro, North Carolina, and The Grove at Louisville, Kentucky, of $2.7 million, $2.7 million and $1.9 million, respectively, entitling the Company to a 9.0% return on its investment upon the respective property being operational.

[2] This amount represents the aggregate difference between the Company’s carrying amount and its underlying equity in the net assets of its investments, which is typically amortized over the life of the related asset. The basis differential occurs primarily due to the other than temporary impairments recorded during 2014, the difference between the allocated value to acquired entity interests and the venture’s basis in those interests, the capitalization of additional investment in the unconsolidated entities, and the elimination of service related revenue to the extent of the Company’s percentage ownership.

[3] This amount represents the aggregate difference between the historical cost basis and the basis reflected at the entity level, which is typically amortized over the life of the related asset. The basis differential occurs primarily due to the impairment recognized during the year ended December 31, 2014 in connection with not exercising the Copper Beech purchase option, offset by the capitalization of transaction costs incurred to acquire the Company's interests in the Copper Beech entities.
