The BB sees them safe until October. But if they go down a point in three months time this means they have to go up in the following period/s to get back to that threshold by October (or when they apply for entry into teh extended scheme). Going down would affirm a downward trend - at some point supporters will start to loose the faith and I think that downgrade would be the tipping point. And its not just one point they are up against - its been flagged it could be two.
They need to be BB to be eligible for entry into the extended scheme. They also need to be a finance business. As mentioned earlier they are now a business involved in helicopters, apples and finance - so presumaby they have to divest those interests by the time they apply. That I think makes them a distresed seller of those assets if the sale doesn't go through soon. The longer tehy leave hte cheaper teh price, the more vulnerabel they become. Best to have that BB secured in 3 months time!
Don't forget the BB is on long term rating. Their short term ratings are already at B (without a positive credit watch) which means facing major ongoing uncertainty.
