In other words, Google,Microsoft, Apple, and Cisco Systems hold a large proportion of the $255 billion held in their foreign subsidiaries in US Treasuries. The tech giants can’t bring cash home and use it to help the government pay its debts – because this money would trigger a tax bill. As a result, the corporations prefer to keep it offshore.
American companies say that a "territorial" type of tax system could avoid double taxation and make sure all businesses compete on equal terms. Undoubtedly, this would also encourage companies to shift their revenues overseas.

Today there’s growing concern that the huge cash mountains held by the largest businesses worldwide may threaten global financial stability.
More than a thousand of the largest US non-financial companies hold $1.48 trillion in cash, according to Moody's, the credit rating agency. In the meantime, more than 20% of the US corporate cash pile is held by Google, Microsoft, Apple, and Cisco.
