2021 Convertible Notes

On January 4, 2018, in connection with its reverse merger with Inotek Pharmaceuticals, Corporation (“Inotek”), the Company assumed the obligations of Inotek under its outstanding convertible notes, with an aggregate principal amount of $52.0 million, (the “2021 Convertible Notes”). The 2021 Convertible Notes were issued in 2016 and were scheduled to mature on August 1, 2021 (the “Maturity Date”). The 2021 Convertible Notes are unsecured and accrue interest at a rate of 5.75% per annum and interest is payable semi-annually on February 1 and August 1 of each year. Each holder of the 2021 Convertible Notes (“Holder”) has the option until the close of business on the second business day immediately preceding the Maturity Date to convert all, or any portion, of the 2021 Convertible Notes held by it at a conversion rate of 31.1876 shares of the Company’s common stock per $1.00 principal amount of 2021 Convertible Notes (the “Conversion Rate”) which is $32.08 per share. The Conversion Rate is subject to adjustment from time to time upon the occurrence of certain events, including the issuance of stock dividends and payment of cash dividends.

The Company, at its option, may redeem for cash all or any portion of the 2021 Convertible Notes if the last reported sale price of a share of the Company’s common stock is equal to or greater than 200% of the Conversion Rate for the 2021 Convertible Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending within the five trading days immediately preceding the date on which the Company provides notice of redemption, at a redemption price equal to 100% of the principal amount of the 2021 Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

The 2021 Convertible Notes are considered a hybrid financial instrument consisting of a fixed interest rate “host” and various embedded features that required evaluation as potential embedded derivatives under FASB ASC 815, Derivatives and Hedging (“ASC 815”). Based on the nature of the host instrument and the embedded features, management concluded that none of the conversion, put and redemption features required bifurcation and separate accounting from the host instrument. The Company determined that the Additional Interest was an embedded derivative that contains non-credit related events of default. As a result, the Additional Interest feature required bifurcation and separate accounting under ASC 815. Based on the amount of Additional Interest that would be owed and the likelihood of occurrence, the Company estimated the fair value of the Additional Interest feature to be insignificant upon issuance and as of March 31, 2021 and December 31, 2020. As of March 31, 2021, the stated interest rate was 5.75%, and the effective interest rate was 15.3%.

2022 Convertible Notes

On February 20, 2020 and June 5, 2020, the Company entered into separate, privately negotiated exchange agreements (the “Exchange Agreements”) with certain holders of the 2021 Convertible Notes. Pursuant to the Exchange Agreements, on February 20, 2020, the Company exchanged approximately $39.35 million aggregate principal amount of the 2021 Convertible Notes (representing approximately 76% of the aggregate outstanding principal amount of the 2021 Convertible Notes) for (a) approximately $39.35 million aggregate principal amount of 6.25% Convertible Senior Notes due August 2022 (the “2022 Convertible Notes”) (an exchange ratio equal to 1.00 2022 Convertible Note per exchanged 2021 Convertible Note) and (b) $0.1 million to pay the accrued and unpaid interest on the exchanged 2021 Convertible Notes from February 1, 2020, to February 20, 2020, the closing date of the February 20, 2020 exchange transactions. Additionally, the Company repurchased 3,000 shares of its common stock that have been retired for an aggregate amount of $71,670 from certain holders of the 2021 Convertible Notes participating in the exchange transactions in privately negotiated, private transactions.

Also pursuant to the Exchange Agreements, on June 12, 2020, the Company exchanged $7.5 million aggregate principal amount of the 2021 Convertible Notes for (a) $7.5 million aggregate principal amount of its newly issued 6.25% Convertible Senior Notes due 2022 (an exchange ratio equal to 1.00 2022 Convertible Notes per exchanged 2021 Convertible Notes) and (b) approximately $11,000 to pay the accrued and unpaid interest on the exchanged 2021 Convertible Notes from, and including, February 1, 2020, to, but excluding, the closing date of the exchange transaction, adjusted to take into account the unearned accrued interest on the 2022 Convertible Notes from, and including, February 20, 2020, to, but excluding, the closing date of the exchange transaction.

The 2022 Convertible Notes were issued in a private placement exempt from registration in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The 2022 Convertible Notes issued in the exchange transaction were issued as additional notes pursuant to the Indenture, dated as of August 5, 2016, between the Company and Wilmington Trust, National Association, as trustee, as supplemented by the Second Supplemental Indenture, dated as of February 20, 2020, governing the 2022 Convertible Notes.

The conversion rate for the 2022 Convertible Notes is initially 31.1876 shares of the Company’s common stock per 1.00 principal amount of 2022 Convertible Notes, which is equivalent to an initial conversion price of approximately $32.06 per share of common stock and is subject to adjustment under the terms of the 2022 Convertible Notes. The Company may redeem for cash all or any portion of the 2022 Convertible Notes, at its option, if the last reported sale price of its common stock is equal to or greater than 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending within the five trading days immediately preceding the date on which the Company provides written notice of redemption. The 2022 Convertible Notes Indenture contains customary terms and covenants and events of default. As of March 31, 2021, the stated interest rate was 6.25%, and the effective interest rate was 15.3%.

In December 2020, $8.5 million principal amount, representing a carrying value of $7.6 million of the 2022 Convertible Notes was converted into 298,562 shares of the Company’s common stock. On April 26, 2021, the Company called for the redemption of the remaining $38.4 million principal balance of the 2022 Convertible Notes (See Note 16) as the Company’s stock price traded above the Conversion Rate for at least 20 trading days during a 30-day consecutive trading period.
