(1)	For the three months ended March 31, 2019, we excluded from the calculation of diluted loss per share 3.3 million shares potentially issuable under incentive compensation plans or convertible securities, as their effect, if included, would have been anti-dilutive.

Our calculation of diluted (loss) earnings per common share excludes shares of common stock that are issuable upon exercise of stock options when the exercise price is greater than the average market price of our common stock. We also exclude unvested restricted stock awards that are antidilutive as a result of unrecognized compensation cost. Such shares averaged 5.4 million and 4.3 million for the three months ended March 31, 2019 and 2018, respectively.
