Subsequent Events	19. Subsequent Events Icahn Enterprises LP Unit Distribution On May 9, 2023, 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 June 30, 2023 to depositary unitholders of record at the close of business on May 22, 2023. Depositary unitholders will have until June 20, 2023 to make a timely election to receive either cash or additional depositary units. If a unitholder does not make a timely election, it will automatically be deemed to have elected to receive the distribution in additional depositary units. Depositary unitholders who elect to receive (or who are deemed to have elected to receive) additional depositary units will receive units valued at the volume weighted average trading price of the units during the five consecutive trading days ending June 27, 2023. Icahn Enterprises will make a cash payment in lieu of issuing fractional depositary units to any unitholders electing to receive (or who are deemed to have elected to receive) depositary units. Repurchase Authorization On May 9, 2023, the Board of Directors of the General Partner approved a repurchase program which authorizes Icahn Enterprises or affiliates of Icahn Enterprises to repurchase up to an aggregate of $500 million worth of any of our outstanding fixed-rate senior unsecured notes issued by Icahn Enterprises and Icahn Enterprises Finance Corp. and up to an aggregate of $500 million worth of the depositary units issued by Icahn Enterprises (the “Repurchase Program”). The repurchases of senior notes or depositary units may be done for cash from time to time in the open market, through tender offers or in privately negotiated transactions upon such terms and at such prices as management may determine. The authorization of the Repurchase Program is for an indefinite term and does not expire until later terminated by the Board of Directors. Investment Funds Redemption Mr. Icahn and his affiliates redeemed $867 million from the Investment segment representing a pro-rata portion of the cash in the Investment segment attributable to Mr. Icahn and his affiliates, which was paid to Mr. Icahn and his affiliates on April 14, 2023. This redemption does not change our liquidity in the Investment segment. Real Estate Subsequent to March 31, 2023, within our Real Estate segment, a significant tenant of a commercial high-rise property was notified of default for non-payment. The tenant stated they are unable to cure the default status and the lease has been terminated. We consider this default, along with other facts and circumstances, a triggering event for potential impairment and we will assess this long-lived asset for any non-cash impairment charges during the second quarter of 2023. As of March 31, 2023, this property had a net book value of $218 million and any potential impairment cannot be estimated at this time.
