We have a portfolio of investments in a number of entities that are primarily focused on the development of real estate and other media and non-media businesses. No investments were individually significant for the periods presented.

We measure our investments, excluding equity method investments, at fair value or, in situations where fair value is not readily determinable, we have the option to value investments at cost plus observable changes in value, less impairment. Additionally, certain investments are measured at net asset value (“NAV”).

As of June 30, 2026 and December 31, 2025, we held $181 million and $223 million, respectively, in investments measured at fair value.
