In a dissolution event, such as a bankruptcy, the Company is entitled to receive the cash-out amount. If the SAFE is outstanding on the three-year anniversary of the Effective Date, then the SAFE will expire and the Company will be entitled to receive the cash-out amount. In the event of a qualifying equity financing, the number of shares of preferred stock received by the Company would be determined by dividing the SAFE investment amount by a discounted price per share of the preferred stock issued in the respective equity financing. The Company recorded an investment of $1 million as an investment in the SAFE on the consolidated balance sheets. Additionally, per the terms of the SAFE arrangement, the Company may be obligated to invest up to an additional $2 million into the SAFE arrangement if Canopy satisfies certain milestones prior to the expiration of the SAFE, or if an equity financing event occurs.

The Company accounted for this investment under ASC 320, Investments - Debt Securities and elected the fair value option for the SAFE investment pursuant to ASC 825, Financial Instruments, which requires financial instruments to be remeasured to fair value each reporting period, with changes in fair value recorded in the consolidated statements of operations. The fair value estimate includes significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The decision to elect the fair value option is determined on an instrument-by-instrument basis on the date the instrument is initially recognized, is applied to the entire instrument, and is irrevocable once elected. For instruments measured at fair value, embedded conversion or other features are not required to be separated from the host instrument. Issuance costs related to convertible securities carried at fair value are not deferred and are recognized as incurred on the consolidated statements of operations.
