Note 9 – Earnings (Loss) Per Share

Earnings (loss) per share is computed using the two-class method. For periods in which the Company reports net income, diluted earnings per share is determined by using the weighted average number of common and dilutive common equivalent shares outstanding during the period, unless the effect is antidilutive. Due to the loss from continuing operations attributable to CVS Health in the three and six months ended June 30, 2018, 1.9 million and 2.3 million, respectively, of potentially dilutive common equivalent shares were excluded from the calculation of diluted earnings per share, as the impact of these shares was antidilutive. In addition, options to purchase 15.3 million and 14.3 million shares of common stock were outstanding, but were not included in the calculation of diluted earnings per share, for the three and six months ended June 30, 2018, respectively, because the exercise prices of the options were greater than the average market price of the common shares and, therefore, the effect would be antidilutive. For the same reason, options to purchase 11.0 million and 9.4 million shares of common stock were outstanding, but were not included in the calculation of diluted earnings per share, for the three and six months ended June 30, 2017, respectively.

The following is a reconciliation of basic and diluted earnings (loss) per share from continuing operations for the respective periods:
