4.0% Senior Secured Convertible Notes Due 2024 (“2024 Notes”)
The fair value of the 2024 Notes as of June 30, 2022 and December 31, 2021 was zero and $24.7 million, respectively. The contractual principal balance of the 2024 Notes as of June 30, 2022 and December 31, 2021 was zero and $27.5 million, respectively.
In April 2022, the Company exchanged the remaining $27.5 million in aggregate principal of the 2024 Notes for approximately 7.8 million shares of the Company’s common stock. The number of shares issued was calculated by dividing $29.4 million, which represented 107% of the principal amount of the notes, plus $0.3 million of interest accrued on the notes, by the average of the daily volume weighted average price for the 10 days immediately preceding April 21, 2022. The Company recognized a loss of $1.8 million in the first quarter of 2022, which included a $0.4 million adjustment to the fair value of the convertible notes to the value of the shares issued under the exchange and a $1.4 million adjustment related to the realization of the amount previously recognized in Accumulated Other Comprehensive Loss. The total loss was recorded in Interest Expense for the six months ended June 30, 2022.
Subsequent to the exchange, the Company has no convertible notes outstanding and the indenture and related security agreement under which the 2024 Notes were issued have been terminated.
Interest on the 2024 Notes was payable quarterly beginning January 15, 2021 at a rate of 4.0% per annum. The following table summarizes contractual interest expense related to the 2024 Notes for the period indicated:
