Not unlike shares outstanding vs shares authorized for distribution.

EDIG has about 285 million shares outstanding but the company has authorization to issue more, up to 350 million.

If EDIG buys back 100 million, for example, the EPS is based on the actual shares held in the market...which would now be 185 million after the 100 million share buyback, not the 350 million authorized.

They may never issue those shares....but have the option.
