Earnings Per Share |
13. | Earnings Per Share
The Company reports earnings per share in accordance with ASC 260, “Earnings Per Share,” which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents then outstanding. Potential common share equivalents consist of restricted stock awards and the incremental common shares issuable upon the exercise of stock options. Under the treasury stock method, unexercised “in-the-money” stock options and warrants are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. In periods when the Company has a net loss, stock awards are excluded from the calculation of earnings per share as their inclusion would have an antidilutive effect. Basic and diluted weighted average shares outstanding were as follows:

At June 30, 2020, there were outstanding options to purchase 768,904 shares of the Company’s common stock at a weighted average exercise price of $38.87 per share and 696,098 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three and six months ended June 30, 2020, 11,578 and 12,328 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore anti-dilutive. At June 30, 2019, there were outstanding options to purchase 985,266 shares of the Company’s common stock at a weighted average exercise price of $30.16 per share and 766,986 shares issuable upon the vesting of stock units. For the three and six months ended June 30, 2019 , 119,026 and 180,160 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore anti-dilutive. As provided by the terms of the indenture underlying the 2016 Notes, the Company had a choice to settle the conversion obligation for the 2016 Notes in cash, shares or any combination of the two. During the third quarter of 2019, the Company settled the remaining 2016 Notes for a total aggregate principal of $115.0 million and 2,316,200 shares of its common stock. As of March 31, 2019, the par value of the 2016 Notes is not included in the calculation of diluted earnings per share, but the dilutive effect of the conversion premium is considered in the calculation of diluted earnings per share using the treasury stock method. The dilutive impact of the 2016 Notes was based on the difference between the Company’s current period average stock price and the conversion price of the 2016 Notes, provided there was a premium. In July 2019, the Company issued $287.5 million aggregate principal amount of the 2019 Notes. As provided by the terms of the indenture underlying the 2019 Notes, conversion of the 2019 Notes will be settled in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. As of June 30, 2020, the 2019 Notes were not convertible. The Company currently intends to settle the par value of the 2019 Notes in cash and any excess conversion premium in shares. The Company applies the provisions of ASC 260, “Earnings Per Share”, Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on the 2019 Notes. Accordingly, the par value of the 2019 Notes is not included in the calculation of diluted income per share, but the dilutive effect of the conversion premium is considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the 2019 Notes is based on the difference between the Company’s current period average stock price and the conversion price of the 2019 Notes, provided there is a premium. Pursuant to this accounting standard, there is no dilution from the accreted principal of the 2019 Notes for the three and six months ended June 30, 2020.
