[1] Represents interest expense related to debt which finances interest-bearing assets. See Note 6, “Debt.”

[2] Net losses allocable to noncontrolling interests in CFVs have been adjusted to exclude noncontrolling interests related to IHS because the Company’s equity interest in IHS is substantial. The Company has little to no equity interest in the other CFVs including the two non-profits, the LTPPs, the LIHTC Funds and the SA Fund.
