"In any case that value was unrealized assets, so it's not like they actually had $36B in cash"

I could equally say that if they liquidated that $26B quickly they would get less than that. I would hope the $36B and $26B were fair estimations of the asset value at the time.

Yes, exactly. Both are fair, market valuations, but (as in any case when you have illiquid assets) a valuation and what you get if you were to liquidate (quickly) are very different things. Cash is King for a good reason!
