[1] Net of $35.1 million and $87.7 million of inter-segment eliminations as of December 31, 2014 and 2013, respectively.
[2] This CDO was not in compliance with its applicable over collateralization tests as of December 31, 2014. Newcastle is not receiving cash flows from this CDO (other than senior management fees and cash flows on senior classes of bonds that were repurchased), since net interest is being used to repay debt, and expects this CDO to remain out of compliance for the forseeable future.
