Certain common stock equivalents were not included in the computation of diluted income per share because the effect would have been anti-dilutive. These common share equivalents totaled less than 0.2 million for each of the three and nine months ended September 30, 2018. For the three and nine months ended September 30, 2019, approximately 0.3 million and 0.2 million, respectively, of common stock equivalents were excluded from the calculation of diluted income per share because they were anti-dilutive.
