Other Investments [Abstract]
Equity Securities without Readily Determinable Fair Value	We 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.

Disclosure of accounting policy for investment in equity security without readily determinable fair value, which does not qualify for practical expedient to estimate fair value using net asset value per share. Includes, but is not limited to, information considered for determining upward and downward adjustment from observable price change.
