Silicon Graphics files for $100 mln stock shelf

WASHINGTON, Nov 1 (Reuters) - Silicon Graphics Inc SGIC.O filed with regulators on Thursday to periodically sell up to $100 million in common stock.

The company said in a registration statement with the U.S. Securities and Exchange Commission that it would use the proceeds from the offering for sales and marketing, research and development, and general corporate purposes.

Under a shelf registration, a company may sell securities in one or more separate offerings with the size, price and terms to be determined at the time of sale.
