Whenever they say that, they mean "sale." It's typical BigCo doublespeak. In their minds, they're trying to convey the impression that they have choices, so that when they negotiate the sale they don't have their backs up against the wall. But everyone knows it means "sale."

From the actual press release:

> These alternatives could include, among others, possible joint ventures, strategic partnerships or alliances, a sale of the Company or other possible transactions.
