Convertible Note
On December 9, 2019, the Company issued a $41.0 million par value Convertible Note (the "Convertible Note") due November 2022, with a stated interest rate of 4.50% per annum. The Company has elected to account for the Convertible Note using the
fair value option allowed under GAAP. Interest is payable quarterly beginning February 1, 2020. The Convertible Note is initially convertible at a rate of $3.05 per share subject to change for anti-dilution adjustments or certain corporate events.
The fair value of the Convertible Note as of March 31, 2020 and December 31, 2019 was $27.6 million and $39.0 million, respectively, and the contractual principal balance as of March 31, 2020 and December 31, 2019 was $36.0 million and $40.5 million, respectively. In electing the fair value option, the Company recognizes changes in fair value related to changes in credit risk, if any, in other comprehensive income and the remaining change in fair value in interest expense. For the three months ended March 31, 2020, the fair value of the Convertible Note decreased $11.4 million which included a $1.1 million adjustment to other comprehensive income attributed to changes in credit risk and a $5.1 million adjustment to interest expense. The change related to credit risk was primarily caused by an increase in credit rating yield for comparable companies during the period.
During the three months ended March 31, 2020, $4.5 million par value of the Convertible Note was converted to 1,546,889 shares of common stock resulting in a loss of $0.9 million, which is included in interest expense.
Any principal repayment of the Convertible Note is at 112% of the par value. Beginning March 1, 2020 the holder of the Convertible Note may require the Company to redeem up to $1.5 million par value ("Redemption Payment") of the Convertible Note monthly. Subject to certain limitations, the Company at its discretion can pay some or all of Redemption Payment in cash or shares of common stock.
The Convertible Note is a senior secured obligation of the Company secured by substantially all assets of the Company and ranks senior to all unsecured debt of the Company. The Convertible Note contains certain covenants, including that we maintain at all times liquidity calculated as unrestricted, unencumbered cash and cash equivalents in a minimum of $8.0 million.
The primary reason for electing the fair value option is for simplification and cost-benefit considerations of accounting for the Convertible Note (the hybrid financial instrument) at fair value in its entirety versus bifurcation of the embedded derivatives. The significant inputs to the valuation of the Convertible Note at fair value are Level 3 inputs since they are not observable directly. The fair value was determined using a binomial lattice valuation model, which is widely used for valuing convertible notes. The significant assumptions used in the model are the credit spread and volatility of the Company's common stock.
The Convertible Note was issued with 15,459,016 warrants to purchase common stock of the Company. The exercise price is the greater of the conversion price of the Convertible Note on the day the warrants become exercisable or the weighted average 30 day price of our common stock. The initial exercise price was $3.05 per share. The warrants are only exercisable at the option of the Company following the full or partial redemption of the Convertible Note. The Convertible Note and the warrants were determined to be freestanding instruments and were accounted for separately.

Purchase Warrants

In December 31, 2018, the Company entered into a Credit Agreement (the "Credit Agreement"), with Marathon Asset Management, LP. In conjunction with entering into the Credit Agreement, the Company issued Common Stock Purchase Warrants (“Initial Warrants”) to purchase 8,053,390 shares of common stock at an exercise price of $1.25 per share. The Credit Agreement was paid in 2019, but the Initial Warrants are still outstanding. Until December 31, 2020, the Company must issue additional Warrants to the Lenders equal to 10%, in the aggregate, of any additional equity issuances on substantially the same terms and conditions of the Initial Warrants, except that (i) the expiration date shall be five years from the issuance date, (ii) the exercise price shall be equal to 110% of the issuance price per share in the relevant issuance, and (iii) the holder shall be entitled to exercise the warrant on a cashless basis at any time.

Currently the Initial Warrants are classified as liability financial instruments and required to be marked-to-market at each balance sheet date with a corresponding charge to interest expense. As of March 31, 2020 and December 31, 2019, the warrant liability for the Initial Warrants was $7.2 million and $16.3 million, respectively. Any additional warrants issued in connection with the Credit Agreement have been classified as equity instruments and are not required to be marked-to-market at each balance sheet date.
