As part of the adoption of Financial Accounting Standards Board (the “FASB”) Accounting Standards Update 2016-09, our excess tax benefit is no longer included in our calculation of diluted shares under the treasury stock method, resulting in an increase of 1.4 shares in the effect of dilutive securities for the three months ended March 31, 2016.

Shares outstanding and loss per share are equal on a basic and diluted basis for the three months ended March 31, 2015 because our potentially dilutive securities are antidilutive as a result of the net loss available to IPG common stockholders. Potential shares of restricted stock, stock options and other equity awards totaling 6.3 were excluded from the diluted loss per share calculation for the three months ended March 31, 2015, because the effect of including these potential shares would be antidilutive.
