NET INCOME PER SHARE
NET INCOME PER SHARE
 
Basic net income per share is calculated by dividing net income attributable to Vantiv, Inc. by the weighted-average shares of Class A common stock outstanding during the period.

Diluted net income per share is calculated assuming that Vantiv Holding is a wholly-owned subsidiary of Vantiv, Inc., therefore eliminating the impact of Fifth Third's non-controlling interest. Pursuant to the Exchange Agreement, the Class B units of Vantiv Holding ("Class B units"), which are held by Fifth Third and represent the non-controlling interest in Vantiv Holding, are convertible into shares of Class A common stock on a one-for-one basis. Based on this conversion feature, diluted net income per share is calculated assuming the conversion of the Class B units on an "if-converted" basis. Due to the Company's structure as a C corporation and Vantiv Holding's structure as a pass-through entity for tax purposes, the numerator in the calculation of diluted net income per share is adjusted accordingly to reflect the Company's income tax expense assuming the conversion of the Fifth Third non-controlling interest into Class A common stock. The adjusted effective tax rate used in the calculation was 36.0% for the three months ended March 31, 2015 and 36.5% for the three months ended March 31, 2014. As of March 31, 2015 and 2014, there were approximately 43.0 million and 48.8 million Class B units outstanding, respectively.
 
In addition to the Class B units discussed above, potentially dilutive securities during the three months ended March 31, 2015 and 2014 included restricted stock awards, the warrant held by Fifth Third which allows for the purchase of Class C units of Vantiv Holding, stock options and performance share awards.
 
The shares of Class B common stock do not share in the earnings or losses of the Company and are therefore not participating securities. Accordingly, basic and diluted net income per share of Class B common stock has not been presented.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except share data):
