In a note to clients — as reported by “Barron’s” ( — Moody Investor’s Service analyst Richard Lane says the “surging” pile of cash of U.S. tech companies that’s “parked overseas” reached $227.5 billion out of a total $457 billion at the end of the March quarter. And Apple is among the top “hoarders” with $74 billion — up from $64 billion in December and just $35 billion at the end of 2010.

Lane refers to SEC filings and Moody’s estimates. “Barron’s” says Microsoft is second after Apple, with $50 billion overseas, Cisco System is third with $42.3 billion, Oracle is fourth with $25.1 billion, and Qualcomm is fifth with $16.5 billion.
