Subsequent Events	21. Subsequent Events Icahn Enterprises Distribution On February 24, 2021, the Board of Directors of the general partner of Icahn Enterprises declared a quarterly distribution in the amount of $2.00 per depositary unit, which will be paid on or about April 28, 2021 to depositary unitholders of record at the close of business on March 26, 2021. Depositary unitholders will have until April 16, 2021 to make an election to receive either cash or additional depositary units; if a holder does not make an election, it will automatically be deemed to have elected to receive the distribution in additional depositary units. Depositary unitholders who elect to receive (or are deemed to have elected to receive) additional depositary units will receive units valued at the volume weighted average trading price of the units on Nasdaq during the 5 consecutive trading days ending April 23, 2021. No fractional depositary units will be issued pursuant to the distribution payment. Icahn Enterprises will make a cash payment in lieu of issuing fractional depositary units to any holders electing to receive depositary units. Any holders that would only be eligible to receive a fraction of a depositary unit based on the above calculation will receive a cash payment. For distributions declared by the Board in prior quarters, the default election (for holders that did not make an election) was a cash distribution. The default election (for holders that do not make an election) for the distribution to be paid on or about April 28, 2021 will be a distribution paid in additional depository units, a change from prior quarters.
