This question is finance-related and taken from the 2015 film The Big Short:

As described in the movie, Burry tried to call BoA, Goldman, and Morgan Stanley, but the call was only returned a week later and Burry complained the value of his short contracts were not still marked to the underlying asset value. What was going on at the banks side? (Hint: Later, there was another call conversation between Burry and Deeb at Goldman should explain what had occurred).
