Results from discontinued operations for the year ended December 31, 2015 reflect a gain of $39.4, principally related to the settlement of the U.S. income tax audit. This includes a tax benefit of $38.3 from the recognition of previously unrecognized tax positions, related net interest income of $3.2, and a $13.2 receivable due from Exelis and Xylem, partially offset by net tax expense of $17.4 from unfavorable audit adjustments. Results from discontinued operations for the year ended December 31, 2014 reflect a loss of $3.9, primarily related to a settlement payment to a former ITT entity.
