[1] On December 12, 2012, PBF Energy Inc. completed an initial public offering which closed on December 18, 2012.

[2] The diluted earnings per share calculation for the year ended December 31, 2012, assumes the conversion of all outstanding PBF LLC Series A Units to Class A common stock of PBF Energy as of the date of the IPO. 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 39.5% effective tax rate) attributable to the converted units. For the year ended December 31, 2013, the potential conversion of 64,164,045 PBF LLC Series A Units was 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.

[3] 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 1,320,000 and 682,500 shares of PBF Energy Class A common stock because they are anti-dilutive for the years ended December 31, 2013 and 2012, respectively.
