Net Earnings Per Share

Basic net income per share of Class A Common Stock is computed by dividing net income attributable to the Company's earnings by the weighted average number of shares of Class A Common Stock outstanding during the period. The weighted average number of shares of Class A Common Stock outstanding used in computing basic net income per share includes fully vested restricted stock units awarded to directors that are entitled to participate in distributions to common shareholders through receipt of additional units of equivalent value to the dividends paid to Class A Common Stock holders.

Diluted net income per share of Class A Common Stock is computed similarly to basic net income per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents using the treasury method, if dilutive. The Company’s restricted LLC Units and non-qualified stock options are considered common stock equivalents for this purpose. The number of additional shares of Class A Common Stock related to these common stock equivalents and stock options are calculated using the treasury stock method.
