The government is to take over not only defaulting financial companies but those “in danger of default”. Five conditions are listed to define default and in-danger-of-default. Two are straightforward—the company will be filing for bankruptcy shortly or its board or shareholders agree to a government takeover.
The other three conditions allow the government to take over even when a company is not filing for bankruptcy and its board/shareholders do not consent. What it means is that the secretary of the Treasury can decide that a company is about to collapse even if it does not look that way to other people.
Wrap your arms around that. The Secretary of Treasury can take over any company they deem "too big to fail" and do with it as they please.
