Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share The calculation of Earnings per share (basic) is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Earnings per share (diluted) is similar to Earnings per share (basic), but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company’s common stock. The following is a reconciliation of the numerator and denominator used in the calculation of basic and diluted earnings per share available to common stockholders:

Average shares outstanding (diluted) | 58.7 |  |  | 54.2 |  |  | 59.0 |  |  | 56.8 |
Average shares outstanding (diluted) in the table above excludes share-based awards that have not satisfied performance conditions and the anti-dilutive effect of the following share-based awards:
| For the Three Months Ended June 30, |  | For the Six Months Ended June 30,

Convertible securities | — |  |  | 2.2 |  |  | — |  |  | — |
The Company may settle portions of its Affiliate equity purchases in shares of its common stock. Because it is the Company’s intent to settle these potential purchases in cash, the calculation of Average shares outstanding (diluted) excludes any potential dilutive effect from possible share settlements of Affiliate equity purchases. In the three and six months ended June 30, 2018, the Company repurchased 0.9 million and 1.7 million shares, respectively, of its common stock at an average price per share of $159.99 and $174.87, respectively.
