[1] The options outstanding were excluded from the diluted share calculation as their effect would have been anti-dilutive.
[2] Including equity in earnings of unconsolidated subsidiaries.
[3] The Income Available for Common Stockholders shown agrees with Newcastle's quarterly report(s) on Form 10-Q as filed with the Securities and Exchange Commission. However, individual line items may vary from such report(s) due to the operations of properties sold, or classified as held for sale, during subsequent periods being retroactively reclassified to Income for Discontinued Operations for all periods presented (Note 3).
[4] Operating expenses-golf includes rental expenses recorded under operating leases for carts and equipment in the amount of $5.0 million for the year ended December 31, 2014.
[5] Net of $35.1 million and $87.7 million of inter-segment eliminations as of December 31, 2014 and 2013, respectively.
[6] 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.
[7] Assets held within non-recourse structures, including all of the assets in the senior housing and CDO segments, are not available to satisfy obligations outside of such financings, except to the extent net cash flow distributions are received from such structures. Furthermore, creditors or beneficial interest holders of these structures generally have no recourse to the general credit of Newcastle. Therefore, the exposure to the economic losses from such structures generally is limited to invested equity in them and economically their book value cannot be less than zero. Therefore, impairment recorded in excess of Newcastle?s investment, which results in negative GAAP book value for a given non-recourse financing structure, cannot economically be incurred and will eventually be reversed through amortization, sales at gains, or as gains at the deconsolidation or termination of such non-recourse financing structure.
