At the end of 2013, nonfinancial U.S. corporations held
$1.64 trillion in cash,
a 12 percent increase from 2012. Apple's cash hoard reached $158.8
billion, or about 9.7 percent of all corporate cash assets.
Additionally, U.S. based multinationals have $1.95 trillion outside of
the country. Much of the increase in international cash balances was
driven by Microsoft, Apple, and IBM.
