________________________

(1) As of September 30, 2020 and September 30, 2021, the Company used the treasury stock method to calculate the dilutive impact of the 2026 and 2028 Convertible Notes because at that time the Company expected to settle the principal amount of these notes in cash and any excess in shares of the Company's Class A common stock. As of September 30, 2020 and September 30, 2021, the conversion spread, calculated using the average market price of Class A common stock during the period consistent with the treasury stock method, had a dilutive impact for the 2026 Convertible Notes on diluted net income per share of Class A common stock when the average market price of the Company's Class A common stock for a given period exceeded the conversion price of $91.03 per share. As of September 30, 2021, the conversion spread for the 2028 Convertible Notes was anti-dilutive as the average market price of the Company's Class A common stock for a given period did not exceed the conversion price of $179.27 per share.
