Apple likely has more than $250 billion in its famously-large cash reserve, per the Wall Street Journal.

One fun stat: The Journal says that in late 2016 the company was accruing cash "at a rate of about $3.6 million an hour."

Why it matters: Washington may be on the verge of a debate on tax reform, and that's going to include questions about how to handle corporate cash that, like Apple's, is largely held overseas.
