Debt conversion, description												(1) during the five business day period after any five consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Holdings’ common stock and the conversion rate on each such trading day; (2) if Holdings distributes to all or substantially all stockholders (i) rights options or warrants entitling them to purchase shares at a discount to the recent average trading price of its common stock (including due to a stockholder rights plan) or (ii) Holdings’ assets or securities or rights, options or warrants to purchase the same with a per share value exceeding 10% of the trading price of Holdings’ stock; or (3) upon the occurrence of specified corporate events as described further in the indenture. Prior to May 15, 2025, holders may convert their 4.50% Convertible Senior Notes during any calendar quarter (and only during such calendar quarter), if the last reported sale price of Holdings’ common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to $18.66 per share, on each applicable trading day. The closing price of Holdings' common stock exceeded $18.66 per share (130% of the initial conversion price of $14.35 per share) during at least 20 of the last 30 trading days of the quarter ended December 31, 2024 and, therefore, the 4.50% Convertible Senior Notes will be convertible during the first quarter of 2025. Beginning May 15, 2025, holders may convert their 4.50% Convertible Senior Notes at any time prior to the close of business on the third scheduled trading day immediately preceding the maturity date. Upon conversion of the 4.50% Convertible Senior Notes, Holdings will deliver cash, shares of its common stock or a combination of cash and shares of its common stock, at its election.
