[1] The Company recorded its investment in OHA, on a month lag. Therefore, the amounts in the Company's financial statements for the three and nine months ended September 30, 2014 and September 30, 2013 were based on balances and results from OHA for the three and nine months ended August 31, 2014 and August 31, 2013, respectively.

[2] LNR consolidates certain commercial mortgage-backed securities and collateralized debt obligation trusts that are considered VIEs (and for which it is the primary beneficiary), that have been included in the amounts presented above. Total revenue presented above includes $5.1 million and $55.5 million for the period from April 1, 2013 to April 19, 2013 and for the period from October 1, 2012 to April 19, 2013, respectively, of servicing fee revenue that is eliminated upon consolidation of the VIE's at the LNR level. This income is then added back through consolidation at the LNR level as an adjustment to income allocable to noncontrolling entities and has no net impact on net income attributable to LNR.

[3] The Company recorded its investment in LNR, which was sold in April 2013, on a one quarter lag.
