Convertible Senior Notes

On May 2, 2017, we completed a private placement of $517.5 million in aggregate principal amount of 2.25% fixed-rate convertible senior notes due May 15, 2024 (the 2024 Notes) and entered into the 2017 Indenture with respect to the 2024 Notes. Interest on the 2024 Notes was due semi-annually on May 15 and November 15 of each year.

In 2020, we repurchased $136.2 million in aggregate principal amount of the 2024 Notes for an aggregate repurchase price of $186.9 million in cash. In 2022, we repurchased $210.8 million in aggregate principal amount of the 2024 Notes for an aggregate repurchase price of $279.0 million in cash.

On or after January 15, 2024, holders of the 2024 Notes had the ability to convert the 2024 Notes at any time until the close of business on the scheduled trading day immediately preceding May 15, 2024. In January 2024, we provided notice to the holders of the 2024 Notes electing to settle all conversions of the 2024 Notes which occur on or after January 15, 2024 in cash. Consequently, the embedded conversion option of the 2024 Notes (the conversion feature) required bifurcation and separate accounting from the 2024 Notes as it no longer qualified for the equity scope exception under ASC 815, Derivatives and Hedging. Upon bifurcation of the conversion feature, we recorded a derivative liability at a fair value of $126.6 million (Level 3) and a corresponding debt discount that was accreted over the remaining term of the 2024 Notes using the straight-line method. Subsequent changes in the fair value of the derivative liability and accretion of the associated debt discount were recorded in other income (expense), net in our condensed consolidated statements of income.

During the second quarter of 2024, holders of the 2024 Notes converted $169.8 million in aggregate principal amount of the 2024 Notes for $308.2 million in cash, reflecting a conversion premium of $138.4 million calculated based on the per share volume-weighted average price (VWAP) for each of the 30 consecutive trading days during the observation period (as more fully described in the 2017 Indenture). The 2024 Notes were settled in full upon maturity on May 15, 2024.

The following table presents a summary of charges recognized in connection with the bifurcation of the conversion feature of the 2024 Notes and conversions of the 2024 Notes by holders during the first six months of 2024.
