Due to a change in the expectation that management may settle all future note conversions solely through shares in the year and quarter ended December 31, 2014, the diluted income from continuing operations per share calculation includes the dilutive effect of convertible debt and is offset by the exclusion of interest expense and deferred financing fees related to the convertible debt of $1.0 million, after-tax and $3.2 million, after-tax for the years ended December 31, 2016 and 2015, respectively.


(2)	In the year ended December 31, 2014, the computation of diluted net earnings per share does not include the effect of convertible debt under the if-converted method, consisting of 13.5 million shares and $5.8 million of additional income, as the effect would have been antidilutive.
