Google has too much cash

Companies whose securities comprise more than 40 percent of their assets can fall under restrictions that govern the mutual fund industry. So Google, which has increased its cash and securities to almost $10 billion since its 2004 initial public offering, asked the U.S. Securities and Exchange Commission late last month for an exemption.

At stake for Mountain View, California-based Google is the chance to move more of its money from low-yielding U.S. government bonds to investment-grade municipal and corporate debt. That would help Google match the investment returns of rivals such as Microsoft Corp., which obtained a similar exemption in 1988.
