of core earnings and core earnings per adjusted diluted common
                                                        share. This non-GAAP
measure includes adjustments for various realized and unrealized

this measure is commonly used by mortgage REITs as an indicator

ability. Please tell us if this measure is used by the registrant's
                                                        management as an
indicator of the registrant's dividend paying ability. If so, please revise
                                                        your filing to disclose
