[1] The net income attributable to PBF Energy, used in the numerator of the diluted earnings per share calculation is adjusted to reflect the net income, as well as the corresponding income tax (based on a 39.1%, 39.6% and 40.2% effective tax rate for the years ended December 31, 2016, 2015 and 2014) attributable to the converted units. The potential conversion of 21,249,314 PBF LLC Series A Units for the year ended December 31, 2014 were excluded from the denominator in computing diluted net income per share because including them would have had an antidilutive effect. As the PBF LLC Series A Units were not included, the numerator used in the calculation of diluted net income per share was equal to the numerator used in the calculation of basic net income per share and does not include the net income and related income tax expense associated with the potential conversion of the PBF LLC Series A Units.

[2] Represents an adjustment to weighted-average diluted shares outstanding to assume the full exchange of common stock equivalents, including options and warrants for PBF LLC Series A Units and options for shares of PBF Energy Class A common stock. Common stock equivalents excludes the effects of options to purchase 5,701,750, 2,943,750 and 2,401,875 shares of PBF Energy Class A common stock because they are anti-dilutive for the years ended December 31, 2016, 2015 and 2014, respectively.
