Other Investments [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure	OTHER INVESTMENTSWe have investments in entities not accounted for under the equity method for which fair values are not readily available. We record these investments at cost (less impairment, if any), adjusted for observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We report the carrying value of these investments in Other assets in the non-current assets section of our consolidated balance sheets. These investments were $0.9 billion and $0.4 billion at December 31, 2021 and 2022, respectively. See Note 14 for additional information about the decrease from December 31, 2021. The cumulative net unrealized gain from adjustments related to Other Investments held at December 31, 2022 is $136 million.
