We use the two-class method for allocating net income to each class of our common stock. Our Class M shares did not become eligible to participate in dividends until a return of investment (ROI) condition had been met for each class. Once eligible, each class of our common stock has equal dividend rights. The ROI condition was met for Class M-2 on March 28, 2017, and for Class M-3 and Class M-4 on April 20, 2017. For purposes of calculating basic weighted average shares outstanding and the allocation of basic income, shares are deemed to be participating in earnings for only the portion of the period after the condition is met. For purposes of calculating diluted weighted average shares outstanding, shares are deemed dilutive as of the beginning of the period.
Dilutive shares are calculated using the treasury stock method. For Class A shares, this method takes into account shares that can be settled into Class A shares, net of a conversion price. The diluted EPS calculations for Class A shares excluded the following shares, restricted stock units (RSUs) and options: | | | | | | | | | | | | | | Three months ended September 30, | | Nine months ended September 30, | | 2018 | | 2017 | | 2018 | | 2017 | Antidilutive shares, RSUs and options excluded from diluted EPS calculation | 34,908,644 |
