Sept 26 (Reuters) - American Greetings Corp said it received a go-private offer from a group led by its chief executive, valuing the company at about $580 million.
The offer of $17.18 per share represents a premium of nearly 20 percent to the stock’s Tuesday close of $14.34.
The company, whose brands include American Greetings, Carlton Cards and Gibson, said it will form a special committee of independent directors to consider the proposal. (Reporting by Chris Jonathan Peters in Bangalore; Editing by Saumyadeb Chakrabarty)
