Athyrium Credit Facility

On October 1, 2018, the Company entered into a credit agreement (the “Athyrium Credit Facility”), with Athyrium Opportunities III Acquisition LP (“Athyrium”) for up to $110.0 million. The Athyrium Credit Facility provides for a Term Loan A in the aggregate principal amount of $75.0 million (the “Term Loan A”), and a Term Loan B in the aggregate principal amount of $35.0 million (the “Term Loan B”). On October 1, 2018, the Company borrowed the entire principal amount of the Term Loan A. The Company may draw down the Term Loan B upon either (i) FDA approval of EYSUVIS for a dry eye disease indication or (ii) reaching certain net product revenues for INVELTYS, in each case, on or prior to June 30, 2020; however, the Company does not expect to satisfy either such condition on or prior to June 30, 2020 and, as a result, does not currently expect that it will be eligible to draw down any of the Athyrium Term Loan B funds. The maturity date of the Athyrium Credit Facility is October 1, 2024, the six-year anniversary of the close.

The Term Loan A bears interest at a rate of 9.875% per annum, with quarterly, interest-only payments until the fourth anniversary of the Term Loan A. The unpaid principal amount of the Term Loan A is due and payable in quarterly installments starting on the fourth anniversary of the loan. The Company may make voluntary prepayments, in whole or in part, and subject to certain exceptions, is required to make mandatory prepayments upon the occurrence of certain events of default as defined in the agreement, including but not limited to, the occurrence of a change of control. In addition, upon payment or repayment of any outstanding balance under the Athyrium Credit Facility, the Company will have to pay a 1% exit fee of the total principal payments (whether mandatory, voluntary, or at maturity) made throughout the term. The exit fee of $0.7 million based on the $75.0 million principal amount outstanding, will be accreted to the carrying amount of the debt using the effective interest method over the term of the loan.

All mandatory and voluntary prepayments of the Athyrium Credit Facility are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs prior to the second anniversary of the applicable date of issuance, an amount equal to the amount by which (a) the present value of 105% of the principal prepaid plus all interest that would have accrued on such principal through such second anniversary exceeds (b) the amount of principal prepaid, (ii) if prepayment occurs on or after the second anniversary of the applicable date of issuance but prior to the third anniversary of such issuance, an amount equal to 3% of the principal prepaid, and (iii) if prepayment occurs on or after the third anniversary of the applicable date of issuance but prior to the fourth anniversary of such issuance, an amount equal to 2% of the principal prepaid. No prepayment premium is due on any principal prepaid after the fourth anniversary of the applicable date of issuance.

The Athyrium Credit Facility includes features requiring (1) additional interest rate upon an event of default accrued at an additional 3%, or a total interest rate of 12.875%, and (2) the lender’s right to declare all outstanding principal and interest immediately payable upon an event of default. These two features were analyzed and determined to be embedded derivatives to be valued as separate financial instruments. These embedded derivatives were bundled and valued as one compound derivative in accordance with the applicable accounting guidance for derivatives and hedging transactions. The Company determined that, due to the unlikely event of default, the embedded derivatives have a de minimis value as of March 31, 2020. The derivative liability will be remeasured at fair value at each reporting date, with changes in fair value being recorded as other income (expense) in the consolidated statements of operations.

The Athyrium Credit Facility is secured by a pledge of substantially all of the Company’s assets and contains affirmative and negative covenants customary for financings of this type, including limitations on the Company’s and its subsidiaries’ ability to, among other things, incur and prepay additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, change in the nature of business, enter into sale and leaseback transactions, make distributions, and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the Athyrium Credit Facility also contains a financial covenant requiring the Company to maintain at least $10.0 million of cash and cash equivalents. As a result of this financial covenant, the Company has recorded $10.0 million as restricted cash as of March 31, 2020 and December 31, 2019.

In connection with the Athyrium Credit Facility, the Company issued a warrant (“Warrant”), to purchase up to 270,835 shares of the Company’s common stock, at an exercise price per share of $12.18456. The Warrant is immediately exercisable as to 184,660 shares and will become exercisable as to the remaining 86,175 shares only upon the Company’s draw of the Term Loan B; however, as noted above, it is unlikely the Company will satisfy either condition to draw down on the Term Loan B. The Warrant is exercisable through October 1, 2025 and is classified as an equity instrument. The Company allocated the proceeds from the Term Loan A to the Warrant using the relative fair value method. The fair value of the Warrant of $1.9 million was recognized as equity and a corresponding debt discount.

In addition, the Company paid certain fees to Athyrium and other third-party service providers. These fees paid to Athyrium were recorded as a debt discount while the fees paid to other third-party service providers were recorded as debt issuance cost. These costs, along with the fair value of the Warrant of $1.9 million are being amortized using the effective interest method over the term of the Athyrium Credit Facility. The amortization of debt discount and debt issuance cost is included in interest expense within the Condensed Consolidated Statements of Operations. As of March 31, 2020, and 2019, the effective interest rate was 11.63% and 11.42%, respectively, which takes into consideration the non-cash accretion of the exit fee and the amortization of the debt discount and issuance costs. During each of the three months ended March 31, 2020 and March 31, 2019, the Company recognized interest expense of $2.1 million, which consisted of amortization of the debt discount of $0.2 million, and the contractual coupon interest expense of $1.9 million.
