Hollywood accounting can take several forms. In one form,
a subsidiary is formed to perform a given activity and the
parent entity will extract money out of the film's revenue
in the form of charges for certain "services". For example,
a film studio has a distribution arm as a sub-entity, which
will then charge the studio a "distribution fee" — essentially,
the studio charging itself a sum it has total control over and
hence control the profitability report of a project.

Likewise, Google USA pays billions in US ad sales profits to Google Ireland for the right to use Google tech for Google search.
When the Irish loophole closes I'm sure they'll think up another "One Weird Trick" to make taxable profits mystically transmute into untaxable expenses.
