The adjusted financial measures facilitate a meaningful analysis and allow more accurate comparisons of our ongoing business operations because they exclude items that may not be indicative of or are unrelated to Nationstar’s and our business segments’ core operating performance, and are better measures for assessing trends in our underlying businesses. These adjustments are consistent with how management views our businesses. Management uses non-GAAP financial measures in making financial, operational and planning decisions and evaluating Nationstar’s and our business segment’s ongoing performance. Adjusted pre-tax income (loss) eliminates the effects of mark-to-market adjustments which primarily reflects unrealized gains or losses based on the changes in fair value measurements of MSRs and their related financial liabilities for which a fair value accounting election was made. These adjustments which can be highly volatile and material due to changes in credit markets, are not necessarily reflective of the gains and losses that will ultimately be realized by Nationstar. Adjusted pre-tax income (loss) also eliminates, as applicable, restructuring costs, rebranding and integration costs, gain (losses) on sales of fixed assets, certain legal settlement costs that are not considered normal operational matters, and other adjustments based on facts and circumstances that would provide investors a supplemental means for evaluating Nationstar’s core operating performance. Adjusted Servicing Profitability calculated as Adjusted Pre-Tax Income divided by average portfolio UPB. Basis points ("bps") are calculated as annualized adjusted servicing pretax income $ amount/Total average UPB X 10000.Interest rate sensitivity as of 12/31/17.Excludes retail title and Real Estate Digital (sold units only) revenue.
