The Company’s significant accounting policies are described in Note 2 to its audited consolidated financial statements for the year ended December 31, 2020, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC on March 5, 2021. Except as discussed below, these accounting policies have not changed during the three months ended March 31, 2021.

The carrying amount of financial instruments consisting of cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses, accrued compensation and current portion of long-term debt included in the Company’s condensed consolidated financial statements are reasonable estimates of fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, management believes the fair value of long-term debt approximates its carrying value.

Authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

The following table presents information related to the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020 (in thousands):

Equity securities with readily determinable fair values are measured at fair value with the changes in fair value recognized through net loss. Upon the filing of the Offer with the AMF in connection with the Tender Offer Agreement, the Company began purchasing outstanding EOS shares and OCEANEs on the open market. As of March 31, 2021, the Company has purchased 2,665,694 shares of EOS, representing approximately 10% of the outstanding shares of EOS, for €6.5 million ($7.6 million). The Company classified the purchased EOS shares within Level 1 of the fair value hierarchy as the shares are traded on the Euronext Paris stock exchange and have a readily determinable fair value. There was approximately $0.1 million in unrealized holding losses recorded in other income and expense on the condensed consolidated statements of operations for the three months ended March 31, 2021.

Debt securities consist of convertible debt securities that the Company does not intend to hold until maturity and are therefore classified as available-for-sale. Available-for-sale debt securities are measured at fair value with the changes in fair value recognized through other comprehensive loss. As of March 31, 2021, the Company has purchased 157,167 OCEANEs, representing approximately 4% of the outstanding OCEANEs, for €1.1 million ($1.3 million). The Company classified the purchased OCEANEs within Level 2 of the fair value hierarchy as the OCEANEs have a directly observable par value. There was approximately $0.1 million in unrealized holding losses recorded in other comprehensive loss on the condensed consolidated statement of comprehensive loss for the three months ended March 31, 2021.

On December 18, 2020, the Company entered into a foreign currency forward contract, with a notional amount of $117.9 million (€95.6 million) to mitigate the foreign currency exchange risk related to the Tender Offer Agreement, denominated in Euros ("EUR"). The contract is not designated as a hedging instrument. The Company classified the derivative liability within Level 2 of the fair value hierarchy as observable inputs are available for the full term of the derivative instrument. The fair value of the forward contract was developed using a market approach based on publicly available market yield curves and the term of the contract. On March 2, 2021, the foreign currency forward contract was settled for €95.6 million ($115.3 million). The company recognized a $1.7 million loss from the change in fair value of the contract during the three months ended March 31, 2021. The loss on the contract settlement was recorded as other expense on the condensed consolidated statement of operations and is included in investing activities in the condensed consolidated statement of cash flows for the three months ended March 31, 2021.

During the second quarter of 2019, the Company issued a liability classified equity award to one of its executive officers. The award will be earned over a 4-year vesting period and upon a specific market condition. As the award will be settled in cash, it is classified as a liability within Level 3 of the fair value hierarchy as the Company is using a probability-weighted income approach, utilizing significant unobservable inputs including the probability of achieving the specified market condition with the valuation updated at each reporting period. The full fair value of the cash settled award was $4.5 million as of March 31, 2021 and is being recognized ratably as the underlying service period is provided.

The following table provides a reconciliation of liabilities measured at fair value using significant unobservable inputs (Level 3) for the three months ended March 31, 2021 (in thousands):

As of March 31, 2021, and for the period ended, there are no recently adopted accounting pronouncements that have a material impact on the Company’s financial statements.

In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848), which refines the scope of Topic 848 and provides clarification surrounding certain optional expedients and exceptions for contract modifications and hedge accounting that apply to contracts affected by the discounting transition. Under ASU 2021-01, modifications related to reference rate reform would not be considered an event that requires reassessment of previous accounting conclusions. The guidance also amends the expedients and exceptions in Topic 848 to tailor the existing guidance towards derivative instruments impacted by the discounting transition. The amendments in ASU 2021-01 are effective immediately for all entities and entities may choose to apply the amendments retrospectively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively to new modifications from any date within an interim period that includes or is subsequent to January 7, 2021. The Company does not intend to early adopt the standard and is in the process of assessing the impact, if any, on its consolidated financial statements and related disclosures.

In August 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40), which simplifies the accounting for convertible instruments. The guidance removes certain accounting models that separate the embedded conversion features from the host contract for convertible instruments. ASU 2020-06 allows for a modified or full retrospective method of transition. This update is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years, and early adoption is permitted. The Company does not intend to early adopt the standard and is in the process of assessing the impact, if any, on its consolidated financial statements and related disclosures.
