Question:

The Walt Disney Company (DIS) held $3.766 billion in cash on December 31, 2011, and total assets of $73.877 billion. Although this may seem extreme, it pales in comparison with Apple Inc. (AAPL), which had $30 billion in cash and short-term investments and $139 billion in total assets. Why do you think Apple has so much cash (compared to Disney)?
