11. | STOCKHOLDERS’ EQUITY
Amendment of Restated Certificate of Incorporation The Company’s Board of Directors unanimously approved an amendment to the Company’s Restated Certificate of Incorporation (Amendment) on February 14, 2018, subject to stockholder approval. At the annual meeting of stockholders of the Company held on May 2, 2018, the Company’s stockholders approved the Amendment, effective as of May 2, 2018. The Amendment increased the number of shares of common stock, par value $.01 per share, that the Company is authorized to issue from 80,000,000 shares to 120,000,000 shares. The Amendment was filed with the Delaware Secretary of State on May 2, 2018. Stock Split On May 2, 2018, the Board of Directors of the Company approved a two-for-one stock split of the Company’s common stock, par value $0.01. The stock split was in the form of a stock dividend distributed on June 18, 2018, to stockholders of record at the close of business on May 23, 2018. The stock split entitled each stockholder to receive one additional share of common stock, par value $0.01, for each share they held as of the record date. All common stock share and per share data for all periods presented in the accompanying consolidated financial statements and notes thereto have been retroactively adjusted to reflect the stock split. Earnings Per Share The following table sets forth the computation of basic and diluted earnings per share (in thousands, except share and per share data):

Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Basic weighted average shares outstanding |  |  | 58,739,670 |  |  |  | 58,785,118 |  |  |  | 58,789,118 |
Effect of dilutive securities: |  |  |  |  |  |  |  |  |  |  |  |
Stock appreciation rights |  |  | 176,700 |  |  |  | 198,642 |  |  |  | 250,238 |
Restricted stock |  |  | 150,932 |  |  |  | 167,160 |  |  |  | 185,982 |
Diluted weighted average shares outstanding |  |  | 59,067,302 |  |  |  | 59,150,920 |  |  |  | 59,225,338 |
Basic earnings per share |  | $ | 2.29 |  |  | $ | 1.62 |  |  | $ | 1.16 |
Diluted earnings per share |  | $ | 2.28 |  |  | $ | 1.61 |  |  | $ | 1.15 |
Diluted earnings per share is computed using the weighted average number of shares determined for the basic earnings per share computation plus the dilutive effect of common stock equivalents using the treasury stock method. The computation of diluted earnings per share excludes the following potentially dilutive securities because the effect would be anti-dilutive:
