Shares of common stock of approximately 0.3 million and 0.2 million at March 31, 2019 and 2018, respectively, that are issuable through the exercise of dilutive securities were not included in the computation of diluted net income per share because their effect would have been antidilutive.

Vested restricted and performance units that entitle the holders to approximately 0.5 million shares of common stock are included in the basic and diluted weighted average shares outstanding calculation because no further consideration is due related to the issuance of the underlying common shares.
