Since the Company expects to settle the principal amount of the outstanding convertible notes maturing in 2021, 2023, 2024 and 2026 in cash, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread for each of the notes has a dilutive impact on diluted net income per share when the market price of the Company’s Class C capital stock at the end of the period exceeds the conversion price per share. The following table presents the conversion spread and conversion price per share of Class C capital stock for each of the convertible senior notes (in thousands, except per share amounts):
