Nope. They have about $10bn in cash. The rest is about $20bn in short term liquid equities, about $10bn in net receivables and vendor trade receivables (meaning money they paid to vendors in advance), about $80bn in long term marketable securities of which about 60% is non-US, almost $10bn in in property value, and another $10bn in intangible assets (including $1bn in inventory). Then there is about $10bn in deferred taxes and goodwill. So the 'cash in the bank' figure of $150bn is actually $10bn... and for a company worth north of $600bn, it's a relatively small percentage.
