Certain of our unvested stock-based awards (including restricted stock units and restricted stock awards) are considered participating securities since these securities have non-forfeitable rights to dividends or dividend equivalents during the contractual period of the award and thus requires the two-class method of computing EPS. As of March 31, 2019, we have no material participating securities.

The calculation of EPS for common stock under the two-class method shown above excludes income attributable to the participating securities from the numerator and excludes the dilutive effect of those awards from the denominator.

We define common stock equivalents as stock-based awards and common stock related to our Convertible Notes (see Note 12 - Debt) outstanding during the period. Common stock equivalents are measured using the treasury stock method, except for the Convertible Notes, which were assessed for their effect on diluted EPS using the more dilutive of the treasury stock method or the if-converted method. Under the provisions of the if-converted method, the Convertible Notes are assumed to be converted and included in the denominator of the EPS calculation and the interest expense, net of tax, recorded in connection with the Convertible Notes is added back to the numerator.
