On November 3, 2017, we acquired the controlling interest (54.5% of the common stock) in Esja, a private corporation in Reykjavik, Iceland. Subsequent to additional capital contributions, our equity ownership has increased to 56.4% as of June 30, 2024. Through Esja and its wholly-owned subsidiary, we operate the FlyOver Iceland attraction.

The minority Esja shareholders have the right to sell (or “put”) their Esja shares to us based on a multiple of 5.0x EBITDA as calculated on the trailing 12 months from the most recently completed quarter before the put option exercise. The put option is only exercisable after August 2022 (the “Reference Date”), and in the event the FlyOver Iceland attraction has earned a minimum of €3.25 million in unadjusted EBITDA during the most recent fiscal year and during the trailing 12-month period prior to exercise (the “Put Option Condition”). The put option is exercisable during a period of 12 months following the Reference Date (the “Option Period”) if the Put Option Condition has been met. If the Put Option Condition has not been met during the first Option Period, the Reference Date will be extended for an additional 12 months up to three times. If the Put Option Condition is met during any of the Option Periods, yet the shares are not exercised prior to the end of the 12-month Option Period, the put option will expire. If the FlyOver Iceland attraction has not achieved the Put Option Condition by December 31, 2024, the put option expires. As of June 30, 2024, the FlyOver Iceland attraction has not achieved the Put Option Condition and we do not anticipate the Put Option Condition to be achieved prior to expiration.

The noncontrolling interest’s carrying value is determined by the fair value of the noncontrolling interest as of the acquisition date and the noncontrolling interest’s share of the subsequent net income or loss. This value is benchmarked against the redemption value of the sellers’ put option. The carrying value is adjusted to the redemption value, provided that it does not fall below the initial carrying value, as determined by the purchase price allocation. We have made a policy election to reflect any changes caused by such an adjustment to retained earnings (accumulated deficit), rather than to current earnings (loss).

Non-redeemable noncontrolling interest represents the portion of equity in a subsidiary that is not attributable, directly or indirectly, to us. Our non-redeemable noncontrolling interest relates to the equity ownership interest that we do not own.
