The following table is a reconciliation of the share amounts used in computing earnings per share:
| Years Ended December 31,
| 2013 |  | 2012 |  | 2011
Weighted average shares outstanding - Basic | 171,271,000 |  |  | 181,551,000 |  |  | 185,882,000 |
Dilutive effect of assumed exercise of employee stock options and SARs and vesting of performance shares and restricted shares | 2,276,000 |  |  | 2,442,000 |  |  | 3,005,000 |
Weighted average shares outstanding - Diluted | 173,547,000 |  |  | 183,993,000 |  |  | 188,887,000 |
Diluted per share amounts are computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and SARs, and vesting of performance shares and restricted shares, as determined using the treasury stock method. For the years ended December 31, 2013, 2012, and 2011, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 0, 2,950,000, and 1,333,000, respectively.
