We note your disclosure that the value of each share option was determined to be the value of the underlying common share less the exercise price since "recent option grants...have been deep in-the-money at their respective grant dates."

Also reconcile your disclosure here to the disclosure on page F-50 discussing inputs to the option pricing "models used." If the intrinsic value valuation applies only to "recent option grants," tell us the number of options valued using intrinsic value, the total fair value related to such option issuances, and the periods over which the compensation will be recognized.

Audited Consolidated Financial Statements of Lilium GmbH Notes to the Consolidated Financial Statements 20. Share-based Payments, page F-48 18. We note that the original terms of your share options allowed holders to settle in cash or shares only if an "exit event" occurs. We further note that the options were modified in November 2020 to give you the discretion to settle them in cash or shares. Please address the following comments related to your share options: Considering the options appear to be cash-settleable only upon a contingent event, tell us how you determined that the shares qualified for classification as cash-settled. Cite the authoritative IFRS accounting guidance you relied upon, such as IAS 37, in determining whether to classify the options as cash-settled or equity-settled. In regards to the option modification, provide the disclosures required by paragraph 47(c) of IFRS 2 in your next amendment. For the post-modification options that continue to be classified as cash-settled awards, also explain to us in sufficient detail why, consistent with your accounting policy disclosure on page F-35, it appears they have not been reclassified within equity considering you believe the exit event is not probable.
