Incremental compensation cost   $ 9,555                
Common stock conversion basis         The convertible common stock is convertible into shares of Class B common stock (or Class A common stock if no Class B common stock is outstanding at the time of such conversion) representing the product of (i) 1.25% of the Company’s fully diluted capital stock outstanding at the time of conversion multiplied by (ii) two times the value of one minus the quotient obtained by dividing the IPO price per share of $28.00 ("IPO Price") by the stock price per share at the time of conversion. The convertible common stock is convertible at the holder’s option from the fifth anniversary of the IPO (April 17, 2031) until the tenth anniversary of the IPO (April 17, 2036), provided that the price of Class A common stock must equal at least two times the IPO Price prior to conversion. If the trading price of Class A common stock has been less than 1.5 times the IPO Price for at least 75% of trading days during the twelve-month period ending immediately prior to the 11-year anniversary of the IPO (April 17, 2037), any outstanding convertible common stock will be automatically forfeited.
